Accounting Policies [Abstract]
Nature of Business and Basis of Presentation	Nature of Business and Basis of Presentation Nature of Business Capital Bancorp, Inc. is a Maryland corporation and bank holding company (the “Company”) for Capital Bank, N.A. (the “Bank”). The Company's primary operations are conducted by the Bank, which operates branches in Rockville, Columbia and North Bethesda, Maryland, Reston, Virginia, and the District of Columbia. The Bank is principally engaged in the business of investing in commercial, real estate, and credit card loans and attracting deposits. The Company originates residential mortgages for sale in the secondary market through Capital Bank Home Loans, our residential mortgage banking arm, and issues credit cards through OpenSky®, a secured, digitally-driven nationwide credit card platform. The Company formed Church Street Capital, LLC (“Church Street Capital”) in 2014 to provide short-term secured real estate financing to Washington, D.C. area investors and developers that may not meet all Bank credit criteria. In addition, the Company owns all of the stock of Capital Bancorp (MD) Statutory Trust I (the “Trust”). The Trust is a special purpose non-consolidated entity organized for the sole purpose of issuing trust preferred securities. In September 2018, the Company completed its initial public offering (“IPO”) of 2,563,046 shares of its common stock at a price to the public of $12.50 per share, 1,834,310 shares of which were sold by the Company and 728,736 shares of which were sold by certain of the Company’s shareholders (the “selling shareholders”). The net proceeds to the Company from the IPO were $19.8 million after deducting the underwriting discount and offering expenses of $3.2 million . The Company did not receive any proceeds from the sales of shares by the selling shareholders. Basis of Presentation The accompanying consolidated financial statements include the activity of the Company and its wholly-owned subsidiaries, the Bank and Church Street Capital. All intercompany transactions have been eliminated in consolidation. The Company reports its activities as a four business segments: commercial banking; mortgage lending; credit cards; and corporate activities. In determining the appropriateness of segment definition, the Company considers components of the business about which financial information is available and regularly evaluated relative to resource allocation and performance assessment. The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”), and conform to general practices within the banking industry. On August 15, 2018, the Company completed a four -for-one stock split of the Company's authorized, issued, and outstanding common stock, par value $.01 per share (the “Stock Split”). At the effective time of the Stock Split, each share of the Company's issued and outstanding common stock was automatically increased to four shares issued and outstanding. No fractional shares were issued in connection with the Stock Split. All share and share-related information presented in these consolidated financial statements have been retroactively adjusted to reflect the increased number of shares resulting from the Stock Split. Significant Accounting Policies: The preparation of consolidated financial statements in accordance with GAAP requires estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosures of contingent assets and liabilities. The basis of the estimates is on historical experience and on various other assumptions that are believed to be reasonable under current circumstances, results of Note 1 - Nature of Business and Basis of Presentation (continued) which form the basis for making judgments about the carrying value of certain assets and liabilities that are not readily available from other sources. Estimates are evaluated on an ongoing basis. Actual results may differ from these estimates under different assumptions or conditions. Cash and cash equivalents For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, interest bearing deposits with banks and federal funds sold. Generally, federal funds are sold for one-day periods. Investment securities Investment securities are classified as available for sale and carried at fair value with unrealized gains and losses included in stockholders’ equity on an after-tax basis. Premiums and discounts on investment securities are amortized or accreted using the interest method. Changes in the fair value of debt securities available for sale are included in stockholder’s equity as unrealized gains and losses, net of the related tax effect. Unrealized losses are periodically reviewed to determine whether the loss represents an other than temporary impairment. Any unrealized losses judged to be other than a temporary impairment will be charged to income. Loans held for sale Mortgage loans originated and intended for sale are recorded at fair value, determined individually, as of the balance sheet date. Fair value is determined based on outstanding investor commitments, or in the absence of such commitments, based on current investor yield requirements. Gains and losses on loan sales are determined by the specific-identification method. The Company’s current practice is to sell residential mortgage loans on a servicing released basis, and, therefore, it has no intangible asset recorded for the value of such servicing. Interest on loans held for sale is credited to income based on the principal amounts outstanding. Upon sale and delivery, loans are legally isolated from the Company and the Company has no ability to restrict or constrain the ability of third‑party investors to pledge or exchange the mortgage loans. The Company does not have the entitlement or ability to repurchase the mortgage loans or unilaterally cause third‑party investors to put the mortgage loans back to the Company. Unrealized and realized gains on loan sales are determined using the specific-identification method and are recognized through mortgage banking activity in the Consolidated Statements of Income. The Company elected to measure loans held for sale at fair value to better align reported results with the underlying economic changes in value of the loans on the Company’s balance sheet. Loans and the allowance for loan losses Loans are stated at the principal amount outstanding, adjusted for deferred origination fees, deferred origination costs, discounts on loans acquired, and the allowance for loan losses. Interest is accrued based on the loan principal balances and stated interest rates. Origination fees and costs are recognized as an adjustment to the related loan yield using approximate interest methods. The Company generally discontinues the accrual of interest when any portion of the principal and interest is 90 days past due and collateral is insufficient to discharge the debt in full. Generally, interest payments on nonaccrual loans are recorded as a reduction of the principal balance. Loans are considered impaired when, based on current information, management believes the Company will not collect all principal and interest payments according to contractual terms. Generally, loans are reviewed for impairment when the risk grade for a loan is downgraded to a classified asset category. The loans are evaluated for appropriate classification, accrual, impairment, and troubled debt restructure status. If collection of principal is evaluated as doubtful, all payments are applied to principal. A modification of a loan is considered a TDR when a borrower is experiencing financial difficulty and the modification constitutes a concession. The Company may consider interest rate reductions, changes to payment terms, extensions of maturities and/or principal reductions. Loans are generally charged-off in part or in full when management determines the loan to be uncollectible. Factors for charge-off that may be considered include: repayments deemed to be projected beyond reasonable time frames, client bankruptcy and lack of assets, and/or collateral deficiencies. The allowance for loan losses is estimated to adequately provide for probable future losses on existing loans. The allowance consists of specific and general components. For loans that are classified as impaired, an allowance is established when the collateral value, if the loan is collateral dependent, or the discounted cash flows of the impaired loan, is lower than the carrying value of that loan. The general component covers pools of nonclassified loans and is based on historical loss experience adjusted for qualitative factors. There may be an unallocated component of the allowance, which reflects the margin of the imprecision inherent in the underlying assumptions used in the method for estimating specific and general losses in the portfolio. Actual loan performance may differ from those estimates. A loss is recognized as a charge to the allowance when management believes that collection of the loan is unlikely. Collections of loans previously charged off are added to the allowance at the time of recovery. The components of the allowance for loan losses represent an estimation done pursuant to ASC Topic 450, “Contingencies,” or ASC Topic 310, “Receivables.” Specific allowances are established in cases where management has identified significant conditions or circumstances related to a specific credit that management believes indicate the probability that a loss may be incurred. The process for determining an appropriate allowance for loan losses is based on a comprehensive, well-documented, and consistently applied analysis of the loan portfolio. The analysis considers significant factors that affect the collectibility of the portfolio and supports the loan losses estimated by this process. It is important to recognize that the related process, methodology, and underlying assumptions require a substantial degree of judgment. Management believes that the allowance for loan losses is adequate; however, determination of the allowance is inherently subjective and requires significant estimates. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions. Evaluation of the potential effects of these factors on estimated losses involves a high degree of uncertainty, including the strength and timing of economic cycles and concerns over the effects of a prolonged economic downturn in the current cycle. In addition, various banking agencies, as an integral part of their examination process, and independent consultants engaged by the Bank, periodically review the Bank’s loan portfolio and allowance for loan losses. Such review may result in recognition of additions to the allowance based on their judgments of information available to them at the time of their examination. The review of the adequacy of the allowance for loan losses includes an assessment of the fair value adjustment for acquired loans in accordance with generally accepted accounting principles. Premises and equipment Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the related property generally over two to seven years . Leasehold improvements are amortized over the estimated term of the respective leases, which may include renewal options where management has the positive intent to exercise such options, or the estimated useful lives of the improvements, whichever is less. Expenditures for maintenance, repairs, and minor replacements are charged to noninterest expenses as incurred. The costs of major renewals and betterments are capitalized, These costs would be included as a component of premises and equipment expenses on the Consolidated Statements of Operations. Leases During the first quarter of 2019, the Company adopted Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 applies a right-of-use (“ROU”) model that requires a lessee to record, for all leases with a lease term of more than 12 months, an asset representing its right to use the underlying asset and a liability to make lease payments. The Company has elected to apply the practical expedients permitting entities to not reassess: 1) whether any expired or existing contracts are or contain leases; 2) the lease classification for any expired or existing leases; and 3) initial direct costs for any existing leases. Additionally, as provided by ASU 2016-02, the Company has elected not to apply the recognition requirements of ASC 842 to short-term leases, defined as leases with a term of 12 months or less, and to recognize the lease payments in net income on short-term leases on a straight-line basis over the lease term. We adopted the guidance using the modified retrospective approach on January 1, 2019 and elected the practical expedients for transition including the transition option provided in ASU 2018-11, Leases (Topic 842) Targeted Improvements, which allowed the Company to initially apply the new leases standard at the adoption date. Consequently, the reporting for the comparative periods presented continued to be in accordance with ASC Topic 840, Leases . Therefore, the 2018 financial results and disclosures have not been adjusted. The Company is largely accounting for our existing operating leases consistent with prior guidance except for the incremental balance sheet recognition for leases. The adoption of this standard resulted in the Company recognizing lease right-of-use assets and related lease liabilities totaling $5.2 million and $5.4 million , respectively, as of January 1, 2019. The difference between the lease assets and the lease liabilities was $146 thousand of deferred rent, which was reclassified to lease liabilities, and the remainder was recorded as an adjustment to retained earnings in the amount of $54 thousand . The adoption of this ASU did not have a significant impact on the Company’s consolidated statement of income. Additional information is included in Note 6 - Leases. Derivative Financial Instruments T he Company enters into commitments to fund residential mortgage loans (interest rate locks) with the intention of selling them in the secondary market. The Company also enters into forward sales agreements for certain funded loans and loan commitments. Unfunded commitments intended for loans held for sale and forward sales agreements are recorded at fair value with changes in fair value recorded as a component of mortgage banking revenue. Loans originated and intended for sale in the secondary market are carried at fair value. For pipeline loans which are not pre-sold to an investor, the Company manages the interest rate risk on rate lock commitments by entering into forward sale contracts, whereby the Company obtains the right to deliver securities to investors in the future at a specified price, Such contracts are accounted for as derivatives and are recorded at fair value as derivative assets or liabilities, with changes in fair value recorded in mortgage banking revenue. The Company accounts for derivative instruments and hedging activities according to guidelines established in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 815-10, Accounting for Derivative Instruments and Hedging Activities , as amended. The Company recognizes all derivatives as either assets or liabilities on the balance sheet and measures those instruments at fair value. Changes in fair value of derivatives designated and accounted for as cash flow hedges, to the extent they are effective as hedges, are recorded in other comprehensive income, net of deferred taxes. Any hedge ineffectiveness would be recognized in the income statement line item pertaining to the hedged item. Fair Value Measurements Fair value is the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for an asset or liability in an orderly transaction between market participants at the measurement date. The degree of management judgment involved in determining the fair value of a financial instrument is dependent upon the availability of quoted market prices or observable market inputs. For financial instruments that are traded actively and have quoted market prices or observable market inputs, there is minimal subjectivity involved in measuring fair value. However, when quoted market prices or observable market inputs are not fully available, significant management judgment may be necessary to estimate fair value. In developing our fair value estimates, we maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy defines Level 1 valuations as those based on quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 valuations include inputs based on quoted prices for similar assets or liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. Level 3 valuations are based on at least one significant assumption not observable in the market, or significant management judgment or estimation, some of which may be internally developed. Financial assets that are recorded at fair value on a recurring basis include investment securities available for sale, loans held for sale, and derivative financial instruments. Financial liabilities that are recorded at fair value on a recurring basis are comprised of derivative financial instruments. See the Fair Value note to our consolidated financial statements. Income Taxes The Company employs the asset and liability method of accounting for income taxes as required by ASC Topic 740, “ Income Taxes .” Under this method, deferred tax assets and liabilities are determined based on differences between the financial statement carrying amounts and the tax basis of existing assets and liabilities (i.e. temporary timing differences) and are measured at the enacted rates that will be in effect when these differences reverse. The Company utilizes statutory requirements for its income tax accounting, and limits risks associated with potentially problematic tax positions that may incur challenge upon audit, where an adverse outcome is more likely than not. Therefore, no provisions are necessary for either uncertain tax positions nor accompanying potential tax penalties and interest for underpayments of income taxes in the Company’s tax reserves. In accordance with ASC Topic 740, the Company may establish a valuation allowance against deferred tax assets in those cases where realization is less than certain. Earnings per share Earnings per share is computed by dividing net income available to common stockholders by the weighted average number of shares outstanding. Diluted earnings per share is computed by dividing net income by the weighted average number of common shares outstanding, adjusted for the dilutive effect of stock options and restricted stock using the treasury stock method. At December 31, 2019 and 2018 , there were 7,628 and 7,000 stock options, respectively, that were not included in the calculation as their effect would have been anti-dilutive. The following is a reconciliation of the numerators and denominators used in computing basic and diluted earnings per common share as adjusted for the Stock Split: Earnings Per Share For the Years Ended December 31, 2019 2018 (dollars in thousands, except per share information) Income Weighted Average Shares Per Share Amount Income Weighted Average Shares Per Share Amount Basic EPS Net income available to common stockholders $ 16,895 13,733,131 $ 1.23 $ 12,767 12,116,459 $ 1.05 Effect of dilutive securities — 235,454 — 345,679 Dilutive EPS per common share $ 16,895 13,968,585 $ 1.21 $ 12,767 12,462,138 $ 1.02 Comprehensive income The Company reports as comprehensive income all changes in stockholders' equity during the year from sources other than stockholders. Other comprehensive income refers to all components (income, expenses, gains, and losses) of comprehensive income that are excluded from net income. The Company's only two components of other comprehensive income are unrealized gains and losses on investment securities available for sale, net of income taxes, and unrealized gains and losses on cash flow hedges, net of income taxes. Information concerning the Company's accumulated other comprehensive income (loss) as of December 31, 2019 , and 2018 are as follows (in thousands): Comprehensive Income For the Years Ended December 31, (in thousands) 2019 2018 Unrealized gains (losses) on securities available for sale $ 18 $ (825 ) Deferred tax (expense) benefit (5 ) 227 Other comprehensive income (loss), net of tax 13 (598 ) Unrealized gains on cash flow hedges — 5 Deferred tax expense — (2 ) Other comprehensive income, net of tax — 3 Total accumulated comprehensive income (loss) $ 13 $ (595 ) Recently issued accounting pronouncements: In June 2016, the FASB issued guidance to change the accounting for loan losses and modify the impairment model for certain debt securities. In October 2019, the FASB voted to delay implementation and the new standard is now effective for fiscal years beginning after December 15, 2022, including the interim periods within those fiscal years. The Company expects the provisions of this standard to impact the Company’s consolidated financial statements, in particular, the level of the reserve for loan losses. The Company is continuing to evaluate the extent of the potential impact and expects that portfolio composition and economic conditions at the time of adoption will be a factor. The Company will apply the amendments to the ASU through a cumulative-effect adjustment to retained earnings as of the beginning of the year of adoption. While early adoption was permitted, the Company did not elect that option. In addition to our allowance for loan losses, the Company will also record an allowance for credit losses on held-to-maturity debt securities instead of applying the impairment model currently utilized. The amount of the adjustments will be impacted by each portfolio’s composition and credit quality at the adoption date as well as economic conditions and forecasts at that time. In August 2018, the FASB amended the Fair Value Measurement Topic 820 disclosure framework. These amendments include additions, removals and modifications to the fair value disclosure requirements in Topic 820, and are effective for the Company for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted on removed or modified disclosures. The Company does not expect these amendments to have a material effect on its financial statements. In April 2019, the FASB issued codification improvements to ASU Topic 326 - Financial Instruments - Credit Loss, Topic 815 - Derivatives and Hedging, and Subtopic 825-10 - Financial Instruments. This codification provides technical corrections and clarifies issues related to fair value hedges. The Company early adopted this guidance upon issuance, and it did not have a material impact on the Company’s Consolidated Financial Statements. In April 2019, the FASB issued guidance that clarifies and improves areas of guidance related to the recently issued standards on loan losses, hedging, and recognition and measurement of financial instruments. The amendments related to loan losses will be effective for the Company for reporting periods beginning after December 15, 2022. The amendments related to hedging were effective for the Company for interim and annual periods beginning after December 15, 2018. The amendments related to recognition and measurement of financial instruments were adopted by the Company during the first quarter of 2018. The Company does not expect these amendments to have a material effect on its financial statements. In November 2019, the FASB issued guidance to defer the effective dates for private companies, not-for-profit organizations, and certain smaller reporting companies applying standards on current expected loan losses (CECL). The new effective dates will be fiscal years beginning after December 15, 2022 including interim periods within those fiscal years. In addition, the FASB issued guidance that addresses issues raised by stakeholders during the implementation of ASU 2016-13, Financial Instruments-loan losses (Topic 326): Measurement of loan losses on Financial Instruments. The amendments affect a variety of Topics in the Accounting Standards Codification. For entities that have not yet adopted the amendments in ASU 2016-13, the amendments are effective for fiscal years beginning after December 15, 2022 including interim periods within those fiscal years. Early adoption is permitted in any interim period as long as an entity has adopted the amendments in ASU 2016-13. The Company does not expect these amendments to have a material effect on its financial statements. In December 2019, the FASB issued guidance to simplify accounting for income taxes by removing specific technical exceptions that often produce information investors have a hard time understanding. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The amendments are effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Early adoption is permitted. The Company does not expect these amendments to have a material effect on its financial statements. Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies are not expected to have a material impact on the Company's financial position, results of operations or cash flows. Reclassifications: Certain reclassifications have been made to the amounts reported in prior periods to conform to the current period presentation. The reclassifications had no effect on net income or total stockholders' equity.

Receivables [Abstract]
Loans Receivable	Major categories of loans are as follows: Loan Categories December 31, (in thousands) 2019 2018 Real estate: Residential $ 427,926 $ 407,844 Commercial 348,091 278,691 Construction 198,702 157,586 Commercial 151,109 122,264 Credit card 46,412 34,673 Other consumer 1,285 1,202 1,173,525 1,002,260 Deferred origination fees, net (2,404 ) (1,992 ) Allowance for loan losses (13,301 ) (11,308 ) Loans receivable, net $ 1,157,820 $ 988,960 The Company makes loans to customers located primarily in the Washington, D.C. metropolitan area. Although the loan portfolio is diversified, its performance will be influenced by the regional economy. The Company’s loan categories are described below. Residential Real Estate Loans . One-to-four family mortgage loans are primarily on owner-occupied primary residences and, to a lesser extent, investor owned residences. Residential loans are originated through the commercial sales teams and Capital Bank Home Loan division. Residential loans also include home equity lines of credit. Owner-occupied residential real estate loans usually have fixed rates for five or seven years and adjust on an annual basis after the initial term based on a typical maturity of 30 years. Investor residential real estate loans are generally based on 25 -year terms with a balloon payment due after five years. Generally, the required minimum debt service coverage ratio is 1.15 . Residential real estate loans have represented a stable and growing portion of the loan portfolio. Commercial Real Estate Loans . Commercial real estate loans are originated on owner-occupied and non-owner-occupied properties. These loans may be more adversely affected by conditions in the real estate markets or in the general economy. Commercial loans that are secured by owner-occupied commercial real estate and primarily collateralized by operating cash flows are also included in this category of loans. As of December 31, 2019 , there were approximately $165.4 million of owner-occupied commercial real estate loans, representing approximately 47.5% of the commercial real estate portfolio. Commercial real estate loan terms are generally extended for 10 years or less and amortize generally over 25 years or less. The interest rates on commercial real estate loans have initial fixed rate terms that adjust typically at 5 years and origination fees are routinely charged for services. Personal guarantees from the principal owners of the business are generally required, supported by a review of the principal owners’ personal financial statements and global debt service obligations. The properties securing the portfolio are generally diverse in terms and type. This diversity helps reduce the exposure to adverse economic events that affect any single industry. Construction Loans . Construction loans are offered within the Company’s Washington, D.C. and Baltimore, Maryland metropolitan operating areas to builders primarily for the construction of single-family homes and condominium and townhouse conversions or renovations and, to a lesser extent, to individuals. Construction loans typically have terms of 12 to 18 months, the Company generally transitions the end purchaser to permanent financing or re-underwriting and selling into the secondary market through Capital Bank Home Loan. According to underwriting standards, the ratio of loan principal to collateral value, as established by an independent appraisal, cannot exceed 75% for investor-owned and 80% for owner-occupied properties. Semi-annual stress testing of the construction loan portfolio is conducted, and underlying real estate conditions are closely monitored as well as the borrower’s trends of sales valuations as compared to underwriting valuations as part of the ongoing risk management efforts. The borrowers’ progress in construction buildout is closely monitored and the original underwriting guidelines for construction milestones and completion timelines are strictly enforced. Commercial Business Loans . In addition to other loan products, general commercial loans, including commercial lines of credit, working capital loans, term loans, equipment financing, letters of credit and other loan products are offered, primarily in target markets, and underwritten based on each borrower’s ability to service debt from income. These loans are primarily made based on the identified cash flows of the borrower and secondarily, on the underlying collateral provided by the borrower. Most commercial business loans are secured by a lien on general business assets including, among other things, available real estate, accounts receivable, promissory notes, inventory and equipment, and personal guaranties from the borrower or other principal are generally obtained. Credit Cards . Through the OpenSky® credit card division, the Company offers credit cards on a nationwide basis to under-banked populations and those looking to rebuild their credit scores are provided through a fully digital and mobile platform. Substantially all of the lines of credit are secured by a noninterest bearing demand account at the Bank in an amount equal to the full credit limit of the credit card. In addition, using a proprietary scoring model, which considers credit score and repayment history (typically a minimum of six months of on-time repayments, but ultimately determined on a case-by-case basis), the Bank has recently begun to offer certain customers an unsecured line in excess of their secured line of credit. Approximately $43.3 million and $32.5 million of the credit card balances were secured by savings deposits held by the Bank as of December 31, 2019 and 2018 , respectively. Other Consumer Loans . To a very limited extent and typically as an accommodation to existing customers, personal consumer loans such as term loans, car loans or boat loans are offered. Loans acquired through acquisitions are recorded at estimated fair value on their purchase date with no carryover of the related allowance for loan losses. In estimating the fair value of loans acquired, certain factors were considered, including the remaining lives of the acquired loans, payment history, estimated prepayments, estimated loss ratios, estimated value of the underlying collateral, and the net present value of cash flows expected. Discounts on loans that were not considered impaired at acquisition were recorded as an accretable discount, which will be recognized in interest income over the terms of the related loans. For loans considered to be impaired, the difference between the contractually required payments and expected cash flows was recorded as a nonaccretable discount. The remaining nonaccretable discounts on loans acquired were $285 thousand and $354 thousand as of December 31, 2019 and 2018 , respectively. Loans with nonaccretable discounts had a carrying value of $1.1 million and $1.3 million as of December 31, 2019 and 2018 , respectively. The activity in the accretable discounts on loans acquired was as follows: Accretable Discounts on Loans Acquired December 31, (in thousands) 2019 2018 Accretable discount at beginning of period $ 438 $ 543 Accretion and payoff of loans (9 ) (105 ) Accretable discount at end of period $ 429 $ 438 The allowance for loan losses consists of specific and general components. The specific component relates to loans that are individually classified as impaired. The general component covers non-impaired loans and is based on historical loss experience adjusted for current economic factors. The following tables present, by class and reserving methodology, the allocation of the allowance for loan losses and the gross investment in loans as of December 31, 2019 and 2018 .

Credit quality indicators As part of the ongoing monitoring of the credit quality of the Company’s loan portfolio, management tracks certain credit quality indicators including trends related to the risk grade of loans, the level of classified loans, net charge-offs, nonperforming loans, and the general economic conditions in the Company’s market. The Company utilizes a risk grading matrix to assign a risk grade to each of its loans. A description of the general characteristics of loans characterized as classified is as follows: Special Mention A special mention loan has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Company’s credit position at some future date. Special mention loans are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification. Borrowers may exhibit poor liquidity and leverage positions resulting from generally negative cash flow or negative trends in earnings. Access to alternative financing may be limited to finance companies for business borrowers and may be unavailable for commercial real estate borrowers. Note 4 - Loans Receivable (continued) Substandard A substandard loan is inadequately protected by the current financial condition and paying capacity of the obligor or of the collateral pledged, if any. Substandard loans have a well-defined weakness, or weaknesses, that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Borrowers may exhibit recent or unexpected unprofitable operations, an inadequate debt service coverage ratio, or marginal liquidity and capitalization. These loans require more intense supervision by Company management. Doubtful A doubtful loan has all the weaknesses inherent as a substandard loan with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. The following table presents the balances of classified loans based on the risk grade. The Company grades all credit cards loans as Pass. Classified loans include Special Mention, Substandard, and Doubtful loans: Classified Loans (in thousands) Pass (1) Special Mention Substandard Doubtful Total December 31, 2019 Real estate: Residential $ 425,661 $ — $ 2,265 $ — $ 427,926 Commercial 340,313 6,345 1,433 — 348,091 Construction 198,702 — — — 198,702 Commercial 145,178 4,505 1,426 — 151,109 Credit card 46,412 — — — 46,412 Other consumer 1,285 — — — 1,285 Total $ 1,157,551 $ 10,850 $ 5,124 $ — $ 1,173,525 December 31, 2018 Real estate: Residential $ 405,532 $ 118 $ 2,194 $ — $ 407,844 Commercial 274,247 2,958 1,486 — 278,691 Construction 154,643 843 2,100 — 157,586 Commercial 117,670 3,844 750 — 122,264 Credit card 34,673 — — — 34,673 Other consumer 1,202 — — — 1,202 Total $ 987,967 $ 7,763 $ 6,530 $ — $ 1,002,260 ________________________ (1) Pass includes loans graded exceptional, very good, good, satisfactory and pass/watch Note 4 - Loans Receivable (continued) Impaired loans also include certain loans that have been modified in troubled debt restructurings (“TDRs”) where economic concessions have been granted to borrowers who have experienced or are expected to experience financial difficulties. These concessions typically result from the Company’s loss mitigation activities and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance or other actions. Certain TDRs are classified as nonperforming at the time of restructure and may only be returned to performing status after considering the borrower’s sustained repayment performance for a reasonable period, generally six months. The status of TDRs is as follows: Troubled Debt Restructurings Number of Contracts Recorded Investment (dollars in thousands) Performing Nonperforming Total December 31, 2019 Real estate: Residential 3 $ — $ 145 $ 145 Commercial 2 — 314 314 Total 5 $ — $ 459 $ 459 Acquired loans included above 3 $ — $ 145 $ 145 December 31, 2018 Real estate: Residential 3 $ — $ 145 $ 145 Commercial 1 — 139 139 Total 4 $ — $ 284 $ 284 Acquired loans included above 3 $ — $ 145 $ 145 During the year ended December 31, 2019 , the Company added one TDR which had a recorded investment of $198 thousand . Of the five loans designated as troubled debt restructure at December 31, 2019 , two loans had a principal payment adjustment and three loans had changes in interest and payment terms. The Company had no defaulted TDR loans in the twelve months ended December 31, 2019 . Of the four loans designated as troubled debt restructured at December 31, 2018 , three loans were classified as TDR due to changes in interest rates and payment terms, and one loan was due to a change in interest rate, payment terms and a principal reduction. There were three restructured loans charged off in the amount of $291 thousand and two performing restructured loans paid off for $3.2 million during the year ended December 31, 2018 .

Lines of credit generally have variable interest rates. Such lines do not represent future cash requirements because it is unlikely that all customers will draw upon their lines in full at any time. Loan commitments generally have variable interest rates, fixed expiration dates, and may require payment of a fee. Letters of credit are conditional commitments issued us to guarantee the performance of a customer to a third party. In the event of nonperformance by the customer in accordance with the terms of the agreement with the third party, the Company would be required to fund the commitment. The Company's maximum exposure to credit loss in the event of nonperformance by the customer is the contractual amount of the credit commitment. Loan commitments and lines of credit are made on the same terms, including collateral, as outstanding loans. The Company is not aware of any accounting loss to be incurred by funding these loan commitments. As of December 31, 2019 and 2018 , respectively, the Company had an allowance for off-balance-sheet credit risk of $1.2 million and $1.1 million , recorded in other liabilities on the consolidated balance sheet. Note 4 - Loans Receivable (continued) The Company maintains a reserve for off balance sheet items such as unfunded lines of credit.

Leases [Abstract]
Lease	Leases On January 1, 2019, the Company adopted ASU 2016-02, Leases, as further explained in Note 1 - Nature of Business and Basis of Presentation. The Company’s primary leasing activities relate to certain real estate leases entered into in support of the Company’s branch operations and back office operations. As of January 1, 2019, the Company had leased five of its full service branches and five other locations for corporate/administration activities, operations, and loan production. All property leases under lease agreements have been been designated as operating leases. The Company does not have leases designated as finance leases. The Company determines if an arrangement is a lease at inception. Operating lease right-of-use (“ROU”) assets are included in premises and equipment, and operating lease liabilities are included as other liabilities in the consolidated balance sheets. ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The weighted average discount rate used was 2.24% . The operating lease ROU asset also includes any lease pre-payments. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which the Company has elected to account for separately as the non-lease component amounts are readily determinable under most leases. As of December 31, 2019 , the Company’s lease ROU assets and related lease liabilities were $3.9 million and $4.3 million , respectively, and have remaining terms ranging from 1 - 6 years , including extension options that the Company is reasonably certain will be exercised. As of December 31, 2019 , the Company had not entered into any material leases that have not yet commenced. The Company’s lease information is summarized as follows: Leases (in thousands) December 31, 2019 Lease Right of Use Asset Lease asset 5,158 Less: Accumulated amortization (1,238 ) Net lease asset 3,920 Lease Liability Lease liability $ 5,358 Less: Accumulated amortization (1,067 ) Net lease liability $ 4,291 Note 6 - Leases (continued) Future minimum payments for operating leases with initial or remaining terms of one year or more are as follows: Lease Payment Obligations (in thousands) December 31, 2019 Amounts due in: 2020 $ 1,265 2021 1,281 2022 921 2023 744 2024 420 Total lease payments $ 4,631 Operating lease and rent expense was $1.3 million and $1.5 million for the years ended December 31, 2019 and 2018 , respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments As part of its mortgage banking activities, the Company enters into interest rate lock commitments, which are commitments to originate loans whereby the interest rate on the loan is determined prior to funding and the customers have locked into that interest rate. The Company then either locks the loan and rate in with an investor and commits to deliver the loan if settlement occurs (Best Efforts) or commits to deliver the locked loan to an investor in a binding (Mandatory) delivery program. Certain loans under rate lock commitments are covered under forward sales contracts. Forward sales contracts are recorded at fair value with changes in fair value recorded in mortgage banking revenue. Interest rate lock commitments and commitments to deliver loans to investors are considered derivatives. The market value of interest rate lock commitments and best efforts contracts are not readily ascertainable with precision because they are not actively traded in stand-alone markets. The Company determines the fair value of rate lock commitments and delivery contracts by measuring the fair value of the underlying asset, which is impacted by current interest rates and takes into consideration the probability that the rate lock commitments will close or will be funded. On January 7, 2015, the Company entered into an interest rate swap transaction with a notional amount of $2 million . The swap qualifies as a derivative and is designated as a hedging instrument. The swap fixed the interest rate the Company paid on the floating rate junior subordinated debentures for four years beginning on March 16, 2015 and matured on March 16, 2019. Based on the notional amount, the Company paid its counterparty quarterly interest at a fixed rate, and counterparty paid the Company interest at a rate of three‑month LIBOR plus 1.87% . The following table reports the commitment and fair value amounts on the outstanding derivatives: Derivatives (in thousands) December 31, 2019 December 31, 2018 Notional amount of open forward sales agreements $ 61,000 $ 25,000 Fair value of open forward delivery sales agreements (125 ) (253 ) Notional amount of open mandatory delivery commitments 22,888 4,256 Fair value of open mandatory delivery commitments 115 59 Notional amount of interest rate lock commitments 32,365 18,776 Fair value of interest rate lock commitments 122 108 Fair value of interest rate swap — 5

Junior subordinated debentures In June 2006, the Company formed Capital Bancorp (MD) Statutory Trust I (the “Trust”) and on June 15, 2006, the Trust issued 2,000 floating Rate Capital Securities (the “Capital Securities”) with an aggregate liquidation value of $2,000,000 to a third party in a private placement. Concurrent with the issuance of the Capital Securities, the Trust issued trust common securities to the Company in the aggregate liquidation value of $62,000 . The proceeds of the issuance of the Capital Securities and trust common securities were invested in the Company’s Floating Rate Junior Subordinated Deferrable Interest Debentures (the “Floating Rate Debentures”). The Floating Rate Debentures for the Trust will mature on June 15, 2036, which may be shortened if certain conditions are met (including the Company having received prior approval of the Board of Governors of the Federal Reserve System and any other required regulatory approvals). These Floating Rate Debentures, which are the only assets of the Trust, are subordinate and junior in right of payment to all present and future senior indebtedness (as defined in the Indenture dated June 15, 2006) of the Company. The Floating Rate Debentures for the Trust accrue interest at a floating rate equal to the three-month LIBOR plus 1.89% , payable quarterly. As of December 31, 2019 and 2018 , the rate for the Trust was 3.76% and 4.68% , respectively. The quarterly distributions on the Capital Securities will be paid at the same rate that interest is paid on the Floating Rate Debentures. The Company has fully and unconditionally guaranteed the Trust’s obligation under the Capital Securities. The Trust must redeem the Capital Securities when the Floating Rate Debentures are paid at maturity or upon any earlier prepayment of the Floating Rate Debentures. The Floating Rate Debentures may be prepaid if certain events occur, including a change in the tax status or regulatory capital treatment of the Capital Securities, or a change in existing laws that requires the Trust to register as an investment company. The junior subordinated debentures are treated as Tier 1 capital, to a limited extent, by the Federal Reserve. Note 10 - Borrowed Funds (Continued) Other subordinated notes On November 24, 2015, the Company issued $13.5 million of subordinated notes. The notes mature on December 1, 2025 and are all callable December 1, 2020. The notes bear interest at 6.95% for the first five years, then adjust to the three‑month LIBOR plus 5.33% adjusted on March 1, June 1, September 1, and December 1 of each year. Interest is payable quarterly. There were related debt issuance costs incurred totaling $278,231 . The costs are amortized to interest expense through the maturity date of the notes.

Capital Standards

Capital Standards	12 Months Ended
	Dec. 31, 2019
Banking and Thrift [Abstract]
Capital Standards	Capital Standards The Company and Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weighting, and other factors. Quantitative measures established and defined by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios of Total, Tier 1 and Common Equity Tier 1 capital to risk-weighted assets, and of Tier 1 capital to average assets. As of December 31, 2019 and 2018, the capital levels of the Company and the Bank substantially exceeded all applicable capital adequacy requirements. Note 14 - Capital Standards (continued) As of December 31, 2019 the most recent notification from the OCC has categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, the Bank must maintain ratios as set forth in the table. There have been no conditions or events since that notification that management believes have changed the Bank’s category. The following table presents actual and required capital ratios as of December 31, 2019 and 2018 for the Bank under the Basel III Capital Rules. The minimum required capital amounts presented include the minimum required capital levels as of December 31, 2019 and 2018 based on the phase-in provisions of the Basel III Capital Rules. Capital levels required to be considered well capitalized are based upon prompt corrective action regulations, as amended to reflect the changes under the Basel III Capital Rules. Based on recent changes to the Federal Reserve’s definition of a “Small Bank Holding Company” that increased the threshold to $3 billion in assets, the Company is not currently subject to separate minimum capital measurements. At such time as the Company reaches the $3 billion asset level, it will again be subject to capital measurements independent of the Bank.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation Compensation cost is recognized for stock options and restricted stock awards issued to employees. Compensation cost is measured as the fair value of these awards on their date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used as the fair value of restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period for stock option awards and as the restriction period for restricted stock awards. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. The expense recognition of employee stock option and restricted stock awards resulted in net expense of approximately $858 thousand and $724 thousand during the years ended December 31, 2019 and 2018 , respectively. All share and per common share amounts have been adjusted to reflect the Stock Split. Refer to Notes 1 and 20 for additional information. Stock options: The Company currently has two incentive compensation plans with outstanding stock options, the 2002 Stock Option Plan and the 2017 Stock and Incentive Compensation Plan (“the Plan”). Only the Plan, which authorizes the use of stock options, stock appreciation rights, restricted stock and/or restricted stock, is available to grant options and shares to employees and directors. At inception the Plan allowed for up to 1,120,000 shares of common stock to be issued. As of December 31, 2019 , there are 302,363 shares available for future grant. Shares of common stock related to any unexercised or unvested award granted under the Plan that terminate or expire, or are subsequently forfeited or cancelled for any reason, become available for re-grant under the Plan. Option prices are equal to or greater than the estimated fair value of the common stock at the date of grant. Options outstanding vest over a four -year period, whereby 25% of the options become exercisable on each anniversary of the grant date. Information with respect to options outstanding during the years ended December 31, 2019 and 2018 is as follows: Stock Options Outstanding 2019 2018 Shares Weighted Average Exercise Price Shares Weighted Average Exercise Price Outstanding at beginning of year 1,431,860 $ 9.38 1,363,444 $ 8.01 Add: Granted 249,300 14.29 373,750 11.44 Less: Exercised (221,710 ) 6.88 (230,894 ) 5.67 Less: Retired on exercise (141,955 ) 6.90 (37,240 ) 5.07 Less: Expired/cancelled/forfeited (9,448 ) 10.89 (37,200 ) 7.34 Outstanding at end of year 1,308,047 $ 11.00 1,431,860 $ 9.38 Exercisable at end of year 592,782 $ 9.40 643,610 $ 7.78 The weighted average fair value of options granted during the years ended December 31, 2019 and 2018 , was $4.30 and $2.56 , respectively.

Stock options with exercise prices greater than the estimated fair value of the stock are not included in this calculation. Total unrecognized compensation expense related to stock options to be recognized over the next five years was $1.7 million and $1.4 million at December 31, 2019 and 2018 , respectively. The intrinsic value of stock options exercised was $1.8 million and $1.3 million during the years ended December 31, 2019 and 2018 , respectively. The weighted average fair value of options granted during 2019 and 2018 were estimated using the Black-Scholes option-pricing model with the following weighted average assumptions: Stock Option Pricing Assumptions 2019 2018 Dividend yield 0.00% 0.00% Risk free interest rate 1.75% 2.53% Expected volatility 34.79% 18.94% Expected life in years 5 5 Restricted stock: The Company from time-to-time also grants shares of restricted stock to key employees. These awards help align the interests of these employees with the interests of the stockholders of the Company by providing economic value directly related to increases in the value of the Company’s stock. These awards typically hold service requirements over various vesting periods. The value of the stock awarded is established as the fair market value of the stock at the time of the grant. The Company recognizes expense, equal to the total value of such awards, ratably over the vesting period of the stock grants. All restricted stock agreements are conditioned upon continued employment. Termination of employment prior to a vesting date, as described below, would terminate any interest in non-vested shares. All restricted shares will fully vest in the event of change in control of the Company. Nonvested restricted stock for the years ended December 31, 2019 and 2018 is summarized in the following table. Restricted Stock Summary 2019 2018 Shares Weighted Average Grant-Date Fair Value Shares Weighted Average Grant-Date Fair Value Nonvested at beginning of year 38,000 $ 10.32 42,000 $ 8.66 Add: Granted — — 12,000 12.38 Less: Vested (18,500 ) 8.16 (16,000 ) 7.50 Less: Forfeited — — — — Nonvested at end of year 19,500 $ 12.38 38,000 $ 10.32 The vesting schedule of restricted shares as of December 31, 2019 is as follows: Restricted Stock Vesting Schedule Year Shares 2020 5,500 2021 5,500 2022 5,500 2023 3,000 19,500 At December 31, 2019 there was $176 thousand of total unrecognized compensation expense related to nonvested restricted stock. At December 31, 2018 , there was $230 thousand of total unrecognized compensation expense related to nonvested restricted stock.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value Generally accepted accounting principles define fair value, establish a framework for measuring fair value, recommend disclosures about fair value, and establish a hierarchy for determining fair value measurement. The hierarchy includes three levels and is based upon the valuation techniques used to measure assets and liabilities. The three levels are as follows: Level 1 - Inputs to the valuation method are quoted prices (unadjusted) for identical assets or liabilities in active markets; Level 2 - Inputs to the valuation method include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument; and Level 3 - Inputs to the valuation method are unobservable and significant to the fair value measurement. Fair value measurements on a recurring basi s Investment securities available for sale - The fair values of the Company's investment securities available for sale are provided by an independent pricing service. The fair values of the Company's securities are determined based on quoted prices for similar securities under Level 2 inputs. Loans held for sale - The fair value of loans held for sale is determined using Level 2 inputs of quoted prices for a similar asset, adjusted for specific attributes of that loan. Derivative financial instruments - Derivative instruments used to hedge residential mortgage loans held for sale and the related interest rate lock commitments include forward commitments to sell mortgage loans and are reported at fair value utilizing Level 2 inputs. The fair values of derivative financial instruments are based on derivative market data inputs as of the valuation date and the underlying value of mortgage loans for rate lock commitments. The interest rate swap is reported at fair value utilizing Level 2 inputs. The Company obtains dealer quotations to value its swap. For purposes of potential valuation adjustments to its derivative position, the Company evaluates the credit risk of its counterparty. Accordingly, the Company has considered factors such as the likelihood of default by the counterparty and the remaining contractual life, among other things, in determining if any fair value adjustment related to credit risk is required. Note 17 - Fair Value (continued) The Company has categorized its financial instruments measured at fair value on a recurring basis as of December 31, 2019 and 2018 as follows: Fair Value of Financial Instruments (in thousands) Total Level 1 Inputs Level 2 Inputs Level 3 Inputs December 31, 2019 Investment securities available for sale U.S. government-sponsored enterprises $ 999 $ — $ 999 $ — Municipal 528 — 528 — Corporate 2,565 — 2,565 — Mortgage-backed securities 56,736 — 56,736 — $ 60,828 $ — $ 60,828 $ — Loans held for sale $ 71,030 $ — $ 71,030 $ — Derivative assets $ 237 $ — $ 237 $ — Derivative liabilities $ 125 $ — $ 125 $ — December 31, 2018 Investment securities available for sale U.S. government-sponsored enterprises $ 17,360 $ — $ 17,360 $ — Municipal 501 — 501 — Corporate 2,885 — 2,885 — Mortgage-backed securities 26,186 — 26,186 — $ 46,932 $ — $ 46,932 $ — Loans held for sale $ 18,526 $ — $ 18,526 $ — Derivative assets $ 172 $ — $ 172 $ — Derivative liabilities $ 253 $ — $ 253 $ — Financial instruments recorded using FASB ASC 825-10 Under FASB ASC 825-10, the Company may elect to report most financial instruments and certain other items at fair value on an instrument-by-instrument basis with changes in fair value reported in net income. After the initial adoption, the election is made at the acquisition of an eligible financial asset, financial liability or firm commitment or when certain specified reconsideration events occur. The fair value election, with respect to an item, may not be revoked once an election is made. The following table reflects the difference between the fair value carrying amount of loans held for sale, measured at fair value under FASB ASC 825-10, and the aggregate unpaid principal amount the Company is contractually entitled to receive at maturity: Fair Value of Loans Held for Sale (in thousands) 2019 2018 Loans held for sale Aggregate fair value $ 71,030 $ 18,526 Contractual principal $ 67,118 $ 17,822 Difference $ 3,912 $ 704 Note 17 - Fair Value (continued) As of December 31, 2019 and 2018 , the Company elected to account for loans held for sale at fair value to eliminate the mismatch that would occur by recording changes in market value on derivative instruments used to hedge loans held for sale while carrying the loans at the lower of cost or market. Fair value measurements on a nonrecurring basis Impaired loans - The Company has measured impairment generally based on the fair value of the loan's collateral and discounted cash flow analysis. Fair value is generally determined based upon independent third-party appraisals of the properties, or discounted cash flows based upon the expected proceeds. These assets are included as Level 3 fair values. As of December 31, 2019 and 2018 , the fair values consist of loan balances of $4.1 million and $4.4 million , with valuation allowances of $119 thousand and $262 thousand , respectively. Foreclosed real estate - The Company's foreclosed real estate is measured at fair value less cost to sell. Fair value was determined based on offers and/or appraisals. Cost to sell the real estate was based on standard market factors. The Company has categorized its foreclosed real estate as Level 3. Fair Value of Impaired Loans and Foreclosed Real Estate (in thousands) 2019 2018 Impaired loans Level 1 Inputs $ — $ — Level 2 Inputs — — Level 3 Inputs 3,980 4,093 Total $ 3,980 $ 4,093 Foreclosed real estate Level 1 Inputs — — Level 2 Inputs — — Level 3 Inputs 2,384 142 Total $ 2,384 $ 142 The following table provides information describing the unobservable inputs used in Level 3 fair value measurements at December 31, 2019 and 2018 : Inputs Valuation Technique Unobservable Inputs General Range of Inputs Impaired Loans Appraised Value/Discounted Cash Flows Discounts to appraisals or cash flows for estimated holding and/or selling costs 0 - 25% Foreclosed Real Estate Appraised Value/Comparable Sales Discounts to appraisals for estimated holding and/or selling costs 0 - 25% Fair value of financial instruments Fair value information about financial instruments, whether or not recognized in the balance sheet, for which it is practical to estimate the value is based upon the characteristics of the instruments and relevant market information. Financial instruments include cash, evidence of ownership in an entity, or contracts that convey or impose on an entity that contractual right or obligation to either receive or deliver cash for another financial instrument. Note 17 - Fair Value (continued) The information used to determine fair value is highly subjective and judgmental in nature and, therefore, the results may not be precise. Subjective factors include, among other things, estimates of cash flows, risk characteristics, credit quality, and interest rates, all of which are subject to change. Since the fair value is estimated as of the balance sheet date, the amounts that will actually be realized or paid upon settlement or maturity on these various instruments could be significantly different. As of December 31, 2019 , the technique used by the Company to estimate the exit price of the loan portfolio consists of similar procedures to those used as of December 31, 2018 , but with added emphasis on both illiquidity risk and credit risk not captured by the previously applied entry price notion. The fair value of the Company’s loan portfolio has always included a credit risk assumption in the determination of the fair value of its loans. This credit risk assumption is intended to approximate the fair value that a market participant would realize in a hypothetical orderly transaction. The Company’s loan portfolio is initially fair valued using a segmented approach. The Company divides its loan portfolio into the following categories: variable rate loans, impaired loans, and all other loans. The results are then adjusted to account for credit risk as described above. However, under the new guidance, the Company believes a further credit risk discount must be applied through the use of a discounted cash flow model to compensate for illiquidity risk, based on certain assumptions included within the discounted cash flow model, primarily the use of discount rates that better capture inherent credit risk over the lifetime of a loan. This consideration of enhanced credit risk provides an estimated exit price for the Company’s loan portfolio. For variable-rate loans that reprice frequently and have no significant change in credit risk, fair values approximate carrying values. Fair values for impaired loans are estimated using discounted cash flow models or based on the fair value of the underlying collateral. The fair value of cash and cash equivalents, interest bearing deposits at other financial institutions, federal funds sold and restricted investments is the carrying amount. Restricted stock includes equity of the Federal Reserve and other banker’s banks. The fair value of noninterest bearing deposits and securities sold under agreements to repurchase is the carrying amount. The fair value of checking and savings deposits, and money market accounts, is the amount payable on demand at the reporting date. Fair value of fixed maturity term accounts and individual retirement accounts is estimated using rates currently offered for accounts of similar remaining maturities. The fair value of certificates of deposit in other financial institutions is estimated based on interest rates currently offered for deposits of similar remaining maturities. The fair value of borrowings is estimated by discounting the value of contractual cash flows using current market rates for borrowings with similar terms and remaining maturities. The fair value of outstanding loan commitments, unused lines of credit, and letters of credit are not included in the table since the carrying value generally approximates fair value. These instruments generate fees that approximate those currently charged to originate similar commitments.

Litigation	Litigation As previously reported in the Company’s quarterly report on Form 10-Q for the quarter ended March 31, 2019, the Bank, along with two other banking institutions, was a defendant in a lawsuit to which on April 9, 2019, the Bank entered into a Settlement Agreement and Joint Tortfeasor Release with the plaintiff. All amounts paid by the Bank were fully funded by its insurance carrier except for $200,000 which was accrued at March 31, 2019 and paid in April, 2019. The Settlement includes a release of all claims in the lawsuit that were or could have been brought and precludes further proceedings. In addition to the lawsuit described above, the Company is involved in legal proceedings occurring in the ordinary course of business. The aggregate effect of these, in management’s opinion, would not be material on the results of operations or financial condition of the Company.

Accounting Policies [Abstract]
Nature of operations	Nature of Business Capital Bancorp, Inc. is a Maryland corporation and bank holding company (the “Company”) for Capital Bank, N.A. (the “Bank”). The Company's primary operations are conducted by the Bank, which operates branches in Rockville, Columbia and North Bethesda, Maryland, Reston, Virginia, and the District of Columbia. The Bank is principally engaged in the business of investing in commercial, real estate, and credit card loans and attracting deposits. The Company originates residential mortgages for sale in the secondary market through Capital Bank Home Loans, our residential mortgage banking arm, and issues credit cards through OpenSky®, a secured, digitally-driven nationwide credit card platform. The Company formed Church Street Capital, LLC (“Church Street Capital”) in 2014 to provide short-term secured real estate financing to Washington, D.C. area investors and developers that may not meet all Bank credit criteria.
Basis of presentation	Basis of Presentation The accompanying consolidated financial statements include the activity of the Company and its wholly-owned subsidiaries, the Bank and Church Street Capital. All intercompany transactions have been eliminated in consolidation. The Company reports its activities as a four business segments: commercial banking; mortgage lending; credit cards; and corporate activities. In determining the appropriateness of segment definition, the Company considers components of the business about which financial information is available and regularly evaluated relative to resource allocation and performance assessment. The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”), and conform to general practices within the banking industry.
Cash and cash equivalents	Cash and cash equivalents For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, interest bearing deposits with banks and federal funds sold. Generally, federal funds are sold for one-day periods.
Investment securities	Investment securities Investment securities are classified as available for sale and carried at fair value with unrealized gains and losses included in stockholders’ equity on an after-tax basis. Premiums and discounts on investment securities are amortized or accreted using the interest method. Changes in the fair value of debt securities available for sale are included in stockholder’s equity as unrealized gains and losses, net of the related tax effect. Unrealized losses are periodically reviewed to determine whether the loss represents an other than temporary impairment. Any unrealized losses judged to be other than a temporary impairment will be charged to income.
Loans held for sale	Loans held for sale Mortgage loans originated and intended for sale are recorded at fair value, determined individually, as of the balance sheet date. Fair value is determined based on outstanding investor commitments, or in the absence of such commitments, based on current investor yield requirements. Gains and losses on loan sales are determined by the specific-identification method. The Company’s current practice is to sell residential mortgage loans on a servicing released basis, and, therefore, it has no intangible asset recorded for the value of such servicing. Interest on loans held for sale is credited to income based on the principal amounts outstanding. Upon sale and delivery, loans are legally isolated from the Company and the Company has no ability to restrict or constrain the ability of third‑party investors to pledge or exchange the mortgage loans. The Company does not have the entitlement or ability to repurchase the mortgage loans or unilaterally cause third‑party investors to put the mortgage loans back to the Company. Unrealized and realized gains on loan sales are determined using the specific-identification method and are recognized through mortgage banking activity in the Consolidated Statements of Income. The Company elected to measure loans held for sale at fair value to better align reported results with the underlying economic changes in value of the loans on the Company’s balance sheet.
Loans and Allowance for Loan Losses	Loans and the allowance for loan losses Loans are stated at the principal amount outstanding, adjusted for deferred origination fees, deferred origination costs, discounts on loans acquired, and the allowance for loan losses. Interest is accrued based on the loan principal balances and stated interest rates. Origination fees and costs are recognized as an adjustment to the related loan yield using approximate interest methods. The Company generally discontinues the accrual of interest when any portion of the principal and interest is 90 days past due and collateral is insufficient to discharge the debt in full. Generally, interest payments on nonaccrual loans are recorded as a reduction of the principal balance. Loans are considered impaired when, based on current information, management believes the Company will not collect all principal and interest payments according to contractual terms. Generally, loans are reviewed for impairment when the risk grade for a loan is downgraded to a classified asset category. The loans are evaluated for appropriate classification, accrual, impairment, and troubled debt restructure status. If collection of principal is evaluated as doubtful, all payments are applied to principal. A modification of a loan is considered a TDR when a borrower is experiencing financial difficulty and the modification constitutes a concession. The Company may consider interest rate reductions, changes to payment terms, extensions of maturities and/or principal reductions. Loans are generally charged-off in part or in full when management determines the loan to be uncollectible. Factors for charge-off that may be considered include: repayments deemed to be projected beyond reasonable time frames, client bankruptcy and lack of assets, and/or collateral deficiencies. The allowance for loan losses is estimated to adequately provide for probable future losses on existing loans. The allowance consists of specific and general components. For loans that are classified as impaired, an allowance is established when the collateral value, if the loan is collateral dependent, or the discounted cash flows of the impaired loan, is lower than the carrying value of that loan. The general component covers pools of nonclassified loans and is based on historical loss experience adjusted for qualitative factors. There may be an unallocated component of the allowance, which reflects the margin of the imprecision inherent in the underlying assumptions used in the method for estimating specific and general losses in the portfolio. Actual loan performance may differ from those estimates. A loss is recognized as a charge to the allowance when management believes that collection of the loan is unlikely. Collections of loans previously charged off are added to the allowance at the time of recovery. The components of the allowance for loan losses represent an estimation done pursuant to ASC Topic 450, “Contingencies,” or ASC Topic 310, “Receivables.” Specific allowances are established in cases where management has identified significant conditions or circumstances related to a specific credit that management believes indicate the probability that a loss may be incurred. The process for determining an appropriate allowance for loan losses is based on a comprehensive, well-documented, and consistently applied analysis of the loan portfolio. The analysis considers significant factors that affect the collectibility of the portfolio and supports the loan losses estimated by this process. It is important to recognize that the related process, methodology, and underlying assumptions require a substantial degree of judgment. Management believes that the allowance for loan losses is adequate; however, determination of the allowance is inherently subjective and requires significant estimates. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions. Evaluation of the potential effects of these factors on estimated losses involves a high degree of uncertainty, including the strength and timing of economic cycles and concerns over the effects of a prolonged economic downturn in the current cycle. In addition, various banking agencies, as an integral part of their examination process, and independent consultants engaged by the Bank, periodically review the Bank’s loan portfolio and allowance for loan losses. Such review may result in recognition of additions to the allowance based on their judgments of information available to them at the time of their examination. The review of the adequacy of the allowance for loan losses includes an assessment of the fair value adjustment for acquired loans in accordance with generally accepted accounting principles.
Premises and equipment	Premises and equipment Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the related property generally over two to seven years . Leasehold improvements are amortized over the estimated term of the respective leases, which may include renewal options where management has the positive intent to exercise such options, or the estimated useful lives of the improvements, whichever is less. Expenditures for maintenance, repairs, and minor replacements are charged to noninterest expenses as incurred. The costs of major renewals and betterments are capitalized, These costs would be included as a component of premises and equipment expenses on the Consolidated Statements of Operations.
Leases	Leases During the first quarter of 2019, the Company adopted Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 applies a right-of-use (“ROU”) model that requires a lessee to record, for all leases with a lease term of more than 12 months, an asset representing its right to use the underlying asset and a liability to make lease payments. The Company has elected to apply the practical expedients permitting entities to not reassess: 1) whether any expired or existing contracts are or contain leases; 2) the lease classification for any expired or existing leases; and 3) initial direct costs for any existing leases. Additionally, as provided by ASU 2016-02, the Company has elected not to apply the recognition requirements of ASC 842 to short-term leases, defined as leases with a term of 12 months or less, and to recognize the lease payments in net income on short-term leases on a straight-line basis over the lease term. We adopted the guidance using the modified retrospective approach on January 1, 2019 and elected the practical expedients for transition including the transition option provided in ASU 2018-11, Leases (Topic 842) Targeted Improvements, which allowed the Company to initially apply the new leases standard at the adoption date. Consequently, the reporting for the comparative periods presented continued to be in accordance with ASC Topic 840, Leases . Therefore, the 2018 financial results and disclosures have not been adjusted. The Company is largely accounting for our existing operating leases consistent with prior guidance except for the incremental balance sheet recognition for leases.
Derivative Financial Instruments	Derivative Financial Instruments T he Company enters into commitments to fund residential mortgage loans (interest rate locks) with the intention of selling them in the secondary market. The Company also enters into forward sales agreements for certain funded loans and loan commitments. Unfunded commitments intended for loans held for sale and forward sales agreements are recorded at fair value with changes in fair value recorded as a component of mortgage banking revenue. Loans originated and intended for sale in the secondary market are carried at fair value. For pipeline loans which are not pre-sold to an investor, the Company manages the interest rate risk on rate lock commitments by entering into forward sale contracts, whereby the Company obtains the right to deliver securities to investors in the future at a specified price, Such contracts are accounted for as derivatives and are recorded at fair value as derivative assets or liabilities, with changes in fair value recorded in mortgage banking revenue. The Company accounts for derivative instruments and hedging activities according to guidelines established in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 815-10, Accounting for Derivative Instruments and Hedging Activities , as amended. The Company recognizes all derivatives as either assets or liabilities on the balance sheet and measures those instruments at fair value. Changes in fair value of derivatives designated and accounted for as cash flow hedges, to the extent they are effective as hedges, are recorded in other comprehensive income, net of deferred taxes. Any hedge ineffectiveness would be recognized in the income statement line item pertaining to the hedged item.
Fair Value Measurements	Fair Value Measurements Fair value is the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for an asset or liability in an orderly transaction between market participants at the measurement date. The degree of management judgment involved in determining the fair value of a financial instrument is dependent upon the availability of quoted market prices or observable market inputs. For financial instruments that are traded actively and have quoted market prices or observable market inputs, there is minimal subjectivity involved in measuring fair value. However, when quoted market prices or observable market inputs are not fully available, significant management judgment may be necessary to estimate fair value. In developing our fair value estimates, we maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy defines Level 1 valuations as those based on quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 valuations include inputs based on quoted prices for similar assets or liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. Level 3 valuations are based on at least one significant assumption not observable in the market, or significant management judgment or estimation, some of which may be internally developed. Financial assets that are recorded at fair value on a recurring basis include investment securities available for sale, loans held for sale, and derivative financial instruments. Financial liabilities that are recorded at fair value on a recurring basis are comprised of derivative financial instruments. See the Fair Value note to our consolidated financial statements.
Income Taxes	Income Taxes The Company employs the asset and liability method of accounting for income taxes as required by ASC Topic 740, “ Income Taxes .” Under this method, deferred tax assets and liabilities are determined based on differences between the financial statement carrying amounts and the tax basis of existing assets and liabilities (i.e. temporary timing differences) and are measured at the enacted rates that will be in effect when these differences reverse. The Company utilizes statutory requirements for its income tax accounting, and limits risks associated with potentially problematic tax positions that may incur challenge upon audit, where an adverse outcome is more likely than not. Therefore, no provisions are necessary for either uncertain tax positions nor accompanying potential tax penalties and interest for underpayments of income taxes in the Company’s tax reserves. In accordance with ASC Topic 740, the Company may establish a valuation allowance against deferred tax assets in those cases where realization is less than certain.
Earnings per share	Earnings per share Earnings per share is computed by dividing net income available to common stockholders by the weighted average number of shares outstanding. Diluted earnings per share is computed by dividing net income by the weighted average number of common shares outstanding, adjusted for the dilutive effect of stock options and restricted stock using the treasury stock method.
Comprehensive income	Comprehensive income The Company reports as comprehensive income all changes in stockholders' equity during the year from sources other than stockholders. Other comprehensive income refers to all components (income, expenses, gains, and losses) of comprehensive income that are excluded from net income. The Company's only two components of other comprehensive income are unrealized gains and losses on investment securities available for sale, net of income taxes, and unrealized gains and losses on cash flow hedges, net of income taxes.
Recently issued accounting pronouncements	Recently issued accounting pronouncements: In June 2016, the FASB issued guidance to change the accounting for loan losses and modify the impairment model for certain debt securities. In October 2019, the FASB voted to delay implementation and the new standard is now effective for fiscal years beginning after December 15, 2022, including the interim periods within those fiscal years. The Company expects the provisions of this standard to impact the Company’s consolidated financial statements, in particular, the level of the reserve for loan losses. The Company is continuing to evaluate the extent of the potential impact and expects that portfolio composition and economic conditions at the time of adoption will be a factor. The Company will apply the amendments to the ASU through a cumulative-effect adjustment to retained earnings as of the beginning of the year of adoption. While early adoption was permitted, the Company did not elect that option. In addition to our allowance for loan losses, the Company will also record an allowance for credit losses on held-to-maturity debt securities instead of applying the impairment model currently utilized. The amount of the adjustments will be impacted by each portfolio’s composition and credit quality at the adoption date as well as economic conditions and forecasts at that time. In August 2018, the FASB amended the Fair Value Measurement Topic 820 disclosure framework. These amendments include additions, removals and modifications to the fair value disclosure requirements in Topic 820, and are effective for the Company for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted on removed or modified disclosures. The Company does not expect these amendments to have a material effect on its financial statements. In April 2019, the FASB issued codification improvements to ASU Topic 326 - Financial Instruments - Credit Loss, Topic 815 - Derivatives and Hedging, and Subtopic 825-10 - Financial Instruments. This codification provides technical corrections and clarifies issues related to fair value hedges. The Company early adopted this guidance upon issuance, and it did not have a material impact on the Company’s Consolidated Financial Statements. In April 2019, the FASB issued guidance that clarifies and improves areas of guidance related to the recently issued standards on loan losses, hedging, and recognition and measurement of financial instruments. The amendments related to loan losses will be effective for the Company for reporting periods beginning after December 15, 2022. The amendments related to hedging were effective for the Company for interim and annual periods beginning after December 15, 2018. The amendments related to recognition and measurement of financial instruments were adopted by the Company during the first quarter of 2018. The Company does not expect these amendments to have a material effect on its financial statements. In November 2019, the FASB issued guidance to defer the effective dates for private companies, not-for-profit organizations, and certain smaller reporting companies applying standards on current expected loan losses (CECL). The new effective dates will be fiscal years beginning after December 15, 2022 including interim periods within those fiscal years. In addition, the FASB issued guidance that addresses issues raised by stakeholders during the implementation of ASU 2016-13, Financial Instruments-loan losses (Topic 326): Measurement of loan losses on Financial Instruments. The amendments affect a variety of Topics in the Accounting Standards Codification. For entities that have not yet adopted the amendments in ASU 2016-13, the amendments are effective for fiscal years beginning after December 15, 2022 including interim periods within those fiscal years. Early adoption is permitted in any interim period as long as an entity has adopted the amendments in ASU 2016-13. The Company does not expect these amendments to have a material effect on its financial statements. In December 2019, the FASB issued guidance to simplify accounting for income taxes by removing specific technical exceptions that often produce information investors have a hard time understanding. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The amendments are effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Early adoption is permitted. The Company does not expect these amendments to have a material effect on its financial statements. Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies are not expected to have a material impact on the Company's financial position, results of operations or cash flows.

The minimum required capital amounts presented include the minimum required capital levels as of December 31, 2019 and 2018 based on the phase-in provisions of the Basel III Capital Rules. Capital levels required to be considered well capitalized are based upon prompt corrective action regulations, as amended to reflect the changes under the Basel III Capital Rules. Based on recent changes to the Federal Reserve’s definition of a “Small Bank Holding Company” that increased the threshold to $3 billion in assets, the Company is not currently subject to separate minimum capital measurements. At such time as the Company reaches the $3 billion asset level, it will again be subject to capital measurements independent of the Bank. For comparison purposes, the Company’s ratios are presented in the following table as well, all of which would have exceeded the “well-capitalized” level had the Company been subject to separate capital minimums.
