When computing earnings per share for an interim period, the denominator is based on the weighted-average shares outstanding during the interim period, and not on an annualized weighted-average basis. Accordingly, the sum of the quarters' earnings per share data will not necessarily equal the year to date earnings per share data.

Accounting Policies [Abstract]
Basis of Presentation	Note 1 – Basis of Presentation General In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly Nicolet Bankshares, Inc. (the “Company”) and its subsidiaries, consolidated balance sheets, statements of income, comprehensive income, changes in stockholders’ equity and cash flows for the periods presented, and all such adjustments are of a normal recurring nature. All material intercompany transactions and balances are eliminated. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the entire year. These interim consolidated financial statements have been prepared according to the rules and regulations of the Securities and Exchange Commission and, therefore, certain information and footnote disclosures normally presented in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) have been omitted or abbreviated. These consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. Critical Accounting Policies and Estimates Preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying disclosures. These estimates are based on management’s best knowledge of current events and actions the Company may undertake in the future. Estimates are used in accounting for, among other items, the allowance for loan losses, useful lives for depreciation and amortization, fair value of financial instruments, deferred tax assets, uncertain income tax positions and contingencies. Estimates that are particularly susceptible to significant change for the Company include the determination of the allowance for loan losses, the assessment of deferred tax assets and liabilities, and the valuation of loans acquired in acquisitions; therefore, these are critical accounting policies. Factors that may cause sensitivity to the aforementioned estimates include but are not limited to: external market factors such as market interest rates and employment rates, changes to operating policies and procedures, changes in applicable banking regulations, and changes to deferred tax estimates. Actual results may ultimately differ from estimates, although management does not generally believe such differences would materially affect the consolidated financial statements in any individual reporting period presented. There have been no material changes or developments with respect to the assumptions or methodologies that the Company uses when applying what management believes are critical accounting policies and developing critical accounting estimates as disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. Recent Accounting Developments Adopted In December 2016, the Financial Accounting Standards Board (“FASB”) issued updated guidance to Accounting Standards Update (“ASU”) 2016-19 Technical Corrections and Improvements In March 2016, the FASB issued updated guidance to ASU 2016-09: Stock Compensation Improvements to Employee Share-Based Payment Activity Operating Segment While the chief decision makers monitor the revenue streams of the various products and services, and evaluate costs, balance sheet positions and quality, all such products, services and activities are directly or indirectly related to the business of community banking, with no regular, formal or material segment delineations. Operations are managed and financial performance is evaluated on a company-wide basis, and accordingly, all the financial service operations are considered by management to be aggregated in one reportable operating segment. Reclassifications Certain amounts in the 2016 consolidated financial statements have been reclassified to conform to the 2017 presentation.

Business Combinations [Abstract]
Acquisitions	Note 2 – Acquisitions First Menasha Bancshares, Inc. (“First Menasha”): On April 28, 2017, the Company consummated its merger with First Menasha pursuant to the Agreement and Plan of Merger by and between the Company and First Menasha dated November 3, 2016, (the “Merger Agreement”), whereby First Menasha was merged with and into the Company, and The First National Bank-Fox Valley, the wholly owned commercial bank subsidiary of First Menasha serving the Fox Valley area of Wisconsin, was merged with and into Nicolet National Bank (the “Bank”). The system integration was completed, and five branches of First Menasha opened, on May 1, 2017, as Nicolet National Bank branches, expanding its presence into Calumet and Winnebago Counties, Wisconsin. Concurrently, Nicolet closed one of its Calumet County locations, bringing the Bank’s footprint to 38 branches as of June 30, 2017. The purpose of the merger was to continue Nicolet’s interest in strategic growth, consistent with its plan to improve profitability through efficiency, leverage the strengths of each bank across the combined customer base, and add shareholder value. With the merger, Nicolet became the leading community bank to serve the Fox Valley area of Wisconsin. Pursuant to the Merger Agreement, the final purchase price consisted of issuing 1,309,885 shares of the Company’s common stock (given the final stock-for-stock exchange ratio of 3.126 except for First Menasha shares owned by the Company immediately prior to the time of the merger), for common stock consideration of $62.2 million (based on $47.52 per share, the volume weighted average closing price of the Company’s common stock over the preceding 20 trading day period) plus cash consideration of $19.3 million. Approximately $0.2 million in direct stock issuance costs for the merger were incurred and charged against additional paid in capital. Upon consummation, the Company added $479 million in assets, $351 million in loans, $375 million in deposits, $4 million in core deposit intangible, and $40 million of goodwill. The Company accounted for the transaction under the acquisition method of accounting, and thus, the financial position and results of operations of First Menasha prior to the consummation date were not included in the accompanying consolidated financial statements. The accounting required assets purchased and liabilities assumed to be recorded at their respective estimated fair values at the date of acquisition. The estimated fair values may be subject to refinement as additional information relative to the closing date fair values becomes available through the measurement period of approximately one year from consummation. Financial advisor business acquired: During the first quarter of 2016, Nicolet agreed in a private transaction to hire a select group of financial advisors and purchase their respective books of business, as well as their operating platform, to enhance the leadership and future growth of the Company’s wealth management business. The transaction was effected in phases and completed April 1, 2016. The Company paid $4.9 million total initial consideration, including $0.8 million cash, $2.6 million of Nicolet common stock, and recorded a $1.5 million earn-out liability payable to one principal in the future (which may require adjustment based on change in initial business purchased over a period, but not contingent upon the principal’s employment). The Company initially recorded $0.4 million of goodwill, $0.2 million of fixed assets, and $4.3 million of customer relationship intangibles (a portion amortizing straight-line over 10 years and a portion over 15 years). The transaction impacts the income statement primarily within brokerage income, personnel expense, and intangibles amortization. Baylake Corp. (“Baylake”): On April 29, 2016, the Company consummated its merger with Baylake. The system integration was completed, and 21 branches of Baylake opened, on May 2, 2016, as branches of the Bank, expanding its presence into Door, Kewaunee, and Manitowoc Counties, Wisconsin. The Company closed one of its Brown County locations concurrently with the Baylake merger, and closed an additional six branches in the fourth quarter of 2016. The purpose of the Baylake merger was for strategic reasons beneficial to the Company. The acquisition was consistent with its plan to drive growth and efficiency through increased scale, leverage the strengths of each bank across the combined customer base, enhance profitability, and add liquidity and shareholder value. Baylake shareholders received 0.4517 shares of the Company’s common stock for each outstanding share of Baylake common stock (except for Baylake shares pre-owned by the Company at the time of the merger), and cash in lieu of any fractional share. Pre-existing Baylake equity awards (restricted stock units and stock options) immediately vested upon consummation of the merger. The Company issued 0.4517 shares of its common stock for each vesting Baylake restricted stock unit, and Nicolet assumed, after appropriate adjustment by the 0.4517 exchange ratio, all pre-existing Baylake stock options. As a result, the Company issued 4,344,243 shares of the Company’s common stock, for common stock consideration of $163.3 million (based on $37.58 per share, the volume weighted average closing price of the Company’s common stock over the preceding 20 trading day period) and recorded an additional $1.2 million consideration for the assumed stock options. Approximately $0.3 million in direct stock issuance costs for the merger were incurred and charged against additional paid in capital. The Company accounted for the transaction under the acquisition method of accounting, and thus, the financial position and results of operations of Baylake prior to the consummation date were not included in the accompanying consolidated financial statements. The fair value of the assets acquired and liabilities assumed on April 29, 2016 was as follows: (in millions) As recorded by Fair Value As Recorded Cash, cash equivalents and securities available for sale $ 262 $ 1 $ 263 Loans 710 (19 ) 691 Other real estate owned 3 (2 ) 1 Core deposit intangible 1 16 17 Fixed assets and other assets 71 (8 ) 63 Total assets acquired $ 1,047 $ (12 ) $ 1,035 Deposits $ 822 $ - $ 822 Junior subordinated debentures, borrowings and other liabilities 116 (1 ) 115 Total liabilities acquired $ 938 $ (1 ) $ 937 Excess of assets acquired over liabilities acquired $ 109 $ (11 ) $ 98 Less: purchase price 164 Goodwill $ 66 The following unaudited pro forma information presents the results of operations for the three and six months ended June 30, 2016, as if the Baylake acquisition had occurred January 1 of that year. These unaudited pro forma results are presented for illustrative purposes and are not intended to represent or be indicative of the actual results of operations of the combined company that would have been achieved had the acquisition occurred at the beginning of each period presented, nor are they intended to represent or be indicative of future results of operations.

Earnings Per Share [Abstract]
Earnings per Common Share	Note 3 – Earnings per Common Share Basic earnings per common share are calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated by dividing net income available to common shareholders by the weighted average number of shares adjusted for the dilutive effect of common stock awards (outstanding stock options and unvested restricted stock), if any. Presented below are the calculations for basic and diluted earnings per common share.

When computing earnings per share for an interim period, the denominator is based on the weighted-average shares outstanding during the interim period, and not on an annualized weighted-average basis. Accordingly, the sum of the quarters' earnings per share data will not necessarily equal the year to date earnings per share data. There were no options outstanding at June 30, 2017 or June 30, 2016 that were excluded from the calculation of diluted earnings per common share as anti-dilutive.

Stock-based Compensation	Note 4 – Stock-based Compensation A Black-Scholes model is utilized to estimate the fair value of stock options and the market price of the Company’s stock at the date of grant is used to estimate the value of restricted stock awards. The weighted average assumptions used in the model for valuing option grants were as follows: Six months ended Year ended Dividend yield 0 % 0 % Expected volatility 25 % 25 % Risk-free interest rate 2.13 % 1.52 % Expected average life 7 years 7 years Weighted average per share fair value of options $ 15.44 $ 11.04 Activity in the Company’s Stock Incentive Plans is summarized in the following tables: Stock Options Weighted- Option Shares Weighted- Exercisable Balance – December 31, 2015 746,004 $ 21.56 325,979 Granted $ 11.04 170,500 36.86 Options assumed in acquisition 91,701 21.03 Exercise of stock options* (84,723 ) 20.98 Forfeited (1,456 ) 21.71 Balance – December 31, 2016 922,026 24.39 439,639 Granted $ 15.44 814,500 48.86 Exercise of stock options* (63,498 ) 19.46 Forfeited (400 ) 16.50 Balance – June 30, 2017 1,672,628 $ 36.49 446,278 *The terms of the stock option agreements permit having a number of shares of stock withheld, the fair market value of which as of the date of exercise is sufficient to satisfy the exercise price and/or tax withholding requirements, and accordingly 3,635 shares were surrendered during the six months ended June 30, 2017 and 10,244 shares were surrendered during the year ended December 31, 2016. These stock options were considered exercised and then surrendered and are included in the Exercise of stock option line. Options outstanding at June 30, 2017 are exercisable at option prices ranging from $9.19 to $49.30. There are 258,875 options outstanding in the range from $9.19 - $20.00, 241,665 options outstanding in the range from $20.01 - $25.00, 154,724 options outstanding in the range from $25.01 - $30.00, 202,864 options outstanding in the range from $30.01 - $40.00 and 814,500 options outstanding in the range from $40.01 - $49.30. At June 30, 2017, the exercisable options have a weighted average remaining contractual life of approximately 5 years and a weighted average exercise price of $20.53. Intrinsic value represents the amount by which the fair market value of the underlying stock exceeds the exercise price of the stock options. The total intrinsic value of options exercised in the first six months of 2017, and full year of 2016 was approximately $1.8 million and $1.3 million, respectively.

The Company recognized approximately $0.9 million and $0.7 million of stock-based employee compensation expense during the six months ended June 30, 2017 and 2016, respectively, associated with its stock equity awards. As of June 30, 2017, there was approximately $16.2 million of unrecognized compensation cost related to equity award grants. The cost is expected to be recognized over the weighted average remaining vesting period of approximately four and one half years.

As of June 30, 2017, the Company does not consider securities with unrealized losses to be other-than-temporarily impaired as the unrealized losses in each category have occurred as a result of changes in interest rates and current market conditions subsequent to purchase, not credit deterioration. The Company has the ability and intent to hold its securities to maturity. There were no other-than-temporary impairments charged to earnings during the six-month periods ending June 30, 2017 or June 30, 2016. The amortized cost and fair values of securities available for sale at June 30, 2017 by contractual maturity are shown below. Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Fair values of securities are estimated based on financial models or prices paid for the same or similar securities. It is possible interest rates could change considerably, resulting in a material change in estimated fair value .

Although the Company has a diversified loan portfolio, the credit risk in the loan portfolio is largely influenced by general economic conditions and trends of the counties and markets in which the debtors operate, and the resulting impact on the operations of borrowers or on the value of underlying collateral, if any. The allowance for loan and lease losses (“ALLL”) represents management’s estimate of probable and inherent credit losses in the Company’s loan portfolio at the balance sheet date. In general, estimating the amount of the ALLL is a function of a number of factors, including but not limited to changes in the loan portfolio, net charge-offs, trends in past due and impaired loans, and the level of potential problem loans, all of which may be susceptible to significant change. To the extent actual outcomes differ from management estimates, additional provisions for loan losses could be required that could adversely affect our earnings or financial position in future periods. Allocations to the ALLL may be made for specific loans but the entire ALLL is available for any loan that, in management’s judgment, should be charged-off or for which an actual loss is realized. The allocation methodology used by the Company includes specific allocations for impaired loans evaluated individually for impairment based on collateral values and for the remaining loan portfolio collectively evaluated for impairment primarily based on historical loss rates and other qualitative factors.

Some credits in these rating categories may require a need for monitoring but elements of concern are not severe enough to warrant an elevated rating. 5 Watch: Credits with this rating are adequately secured and performing but are being monitored due to the presence of various short-term weaknesses which may include unexpected, short-term adverse financial performance, managerial problems, potential impact of a decline in the entire industry or local economy and delinquency issues. Loans to individuals or loans supported by guarantors with marginal net worth or collateral may be included in this rating category. 6 Special Mention: Credits with this rating have potential weaknesses that, without the Company’s attention and correction may result in deterioration of repayment prospects. These assets are considered Criticized Assets. Potential weaknesses may include adverse financial trends for the borrower or industry, repeated lack of compliance with Company requests, increasing debt to net worth, serious management conditions and decreasing cash flow. 7 Substandard: Assets with this rating are characterized by the distinct possibility the Company will sustain some loss if deficiencies are not corrected. All foreclosures, liquidations, and non-accrual loans are considered to be categorized in this rating, regardless of collateral sufficiency. 8 Doubtful: Assets with this rating exhibit all the weaknesses as one rated Substandard with the added characteristic that such weaknesses make collection or liquidation in full highly questionable. 9 Loss: Assets in this category are considered uncollectible. Pursuing any recovery or salvage value is impractical but does not preclude partial recovery in the future.

For determining the adequacy of the ALLL, management defines impaired loans as nonaccrual credit relationships over $250,000, all loans determined to be troubled debt restructurings, plus additional loans with impairment risk characteristics. At the time an individual loan goes into nonaccrual status, however, management evaluates the loan for impairment and possible charge-off regardless of loan size. In determining the appropriateness of the ALLL, management includes allocations for specifically identified impaired loans and loss factor allocations for all remaining loans, with a component primarily based on historical loss rates and another component primarily based on other qualitative factors. Impaired loans are individually assessed and are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or, as a practical expedient, at the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent. Loans that are determined not to be impaired are collectively evaluated for impairment, stratified by type and allocated loss ranges based on the Company’s actual historical loss ratios for each strata, and adjustments are also provided for certain current environmental and qualitative factors. An internal loan review function rates loans using a grading system based on nine different categories. Loans with grades of seven or higher (“classified loans”) represent loans with a greater risk of loss and may be assigned allocations for loss based on specific review of the weaknesses observed in the individual credits if classified as impaired. Classified loans are constantly monitored by the loan review function to ensure early identification of any deterioration. The following tables present impaired loans as of June 30, 2017 and December 31, 2016.

In April 2017, the First Menasha merger added purchased credit impaired loans at a fair value of $5.4 million, net of an initial $5.9 million non-accretable mark. Including these credit impaired loans acquired in the First Menasha merger, total purchased credit impaired loans acquired in aggregate were initially recorded at a fair value of $42.9 million on their respective acquisition dates, net of an initial $32.0 million non-accretable mark and a zero accretable mark. At June 30, 2017, $15.8 million of the $42.9 million remain in impaired loans and $0.8 million of acquired loans have subsequently become impaired, bringing acquired impaired loans to $16.6 million.

These five loans had a combined premodification balance of $1.0 million. There were no other loans which were modified and classified as troubled debt restructurings at June 30, 2017. There were no loans classified as troubled debt restructurings during the previous twelve months that subsequently defaulted as of June 30, 2017. Loans which were considered troubled debt restructurings by First Menasha and Baylake prior to acquisition are not required to be classified as troubled debt restructurings in the Company’s consolidated financial statements unless and until such loans subsequently meet criteria to be classified as such, since acquired loans were recorded at their estimated fair values at the time of the acquisition.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets and Mortgage Servicing Rights	Note 7 – Goodwill and Intangible Assets and Mortgage Servicing Rights The excess of the purchase price in an acquisition over the fair value of net assets acquired consists primarily of goodwill, core deposit intangibles and other identifiable intangibles (primarily related to customer relationships acquired). Goodwill is not amortized but is instead subject to impairment tests on at least an annual basis. Core deposit intangibles, which arise from value ascribed to the deposit base of a bank acquired, have estimated finite lives and are amortized on an accelerated basis to expense over a 10-year period. The other intangibles, which represent value ascribed to financial advisor books of business purchased in 2016 in a private transaction, have estimated finite lives and are amortized on a straight-line basis to expense over their life. Management periodically reviews the carrying value of its long-lived and intangible assets to determine if any impairment has occurred, in which case an impairment charge would be recorded as an expense in the period of impairment, or whether changes in circumstances have occurred that would require a revision to the remaining useful life which would impact expense prospectively. In making such determination, management evaluates whether there are any adverse qualitative factors indicating that an impairment may exist, as well as the performance, on an undiscounted basis, of the underlying operations or assets which give rise to the intangible. The Company’s annual assessments indicated no impairment charge on goodwill or core deposit intangible was required for 2016 or the first six months of 2017.

At each reporting date, impairment is assessed based on an estimated fair value using estimated prepayment speeds of the underlying mortgage loans serviced and stratifications based on the risk characteristics of the underlying loans serviced (predominantly loan type and note interest rate). No valuation or impairment charge was recorded for 2016 or year to date 2017. The following table shows the estimated future amortization expense for amortizing intangible assets. The projections are based on existing asset balances, the current interest rate environment and prepayment speeds as of the June 30, 2017. The actual amortization expense the Company recognizes in any given period may be significantly different depending upon acquisition or sale activities, changes in interest rates, prepayment speeds, market conditions, regulatory requirements and events or circumstances that indicate the carrying amount of an asset may not be recoverable.

Subordinated Borrowings [Abstract]
Junior Subordinated Debentures	Note 9 – Junior Subordinated Debentures At June 30, 2017 and December 31, 2016, the Company’s carrying value of junior subordinated debentures was $29.3 million and $24.7 million, respectively. At June 30, 2017 and December 31, 2016, $28.2 million and $23.7 million, respectively, of guaranteed preferred beneficial interests (“trust preferred securities”) qualify as Tier 1 capital. In July 2004 Nicolet Bankshares Statutory Trust I (the “Statutory Trust”), issued $6.0 million of trust preferred securities that qualify as Tier 1 capital under Federal Reserve Board guidelines. All of the common securities of the Statutory Trust are owned by the Company. The proceeds from the issuance of the common securities and the trust preferred securities were used by the Statutory Trust to purchase $6.2 million of junior subordinated debentures of the Company, which pay an 8% fixed rate. Interest on these debentures is current. The debentures may be redeemed in part or in full, on or after July 15, 2009 at par plus any accrued but unpaid interest. The maturity date of the debenture, if not redeemed, is July 15, 2034. In April 2013, as part of the Mid-Wisconsin Financial Services, Inc. (“Mid-Wisconsin”) acquisition, the Company assumed $10.3 million of junior subordinated debentures issued in December 2005 by Mid-Wisconsin, related to $10.0 million of trust preferred securities issued by a statutory trust, whose common securities were wholly owned by Mid-Wisconsin. These trust preferred securities and debentures mature on December 15, 2035 and have a floating rate of the three-month LIBOR plus 1.43%, adjusted quarterly. Interest on these debentures is current. The interest rates were 2.68% and 2.39% as of June 30, 2017 and December 31, 2016, respectively. The debentures may be called at par plus any accrued but unpaid interest, in part or in full, on or after December 15, 2010. At acquisition the debentures were recorded at an initial fair market value of $5.8 million, with the initial $4.5 million discount being accreted to interest expense over the remaining life of the debentures. At June 30, 2017, the carrying value of these junior debentures was $6.7 million. As part of the 2016 acquisition of Baylake, the Company assumed $16.6 million of junior subordinated debentures related to $16.1 million of issued trust preferred securities. The trust preferred securities and the debentures mature on September 30, 2036 and have a floating rate of three-month LIBOR plus 1.35% adjusted quarterly. Interest on these debentures is current. The interest rates were 2.65% and 2.35% as of June 30, 2017 and December 31, 2016 respectively. The debentures may be redeemed on any interest payment date at par in part or in full, on or after June 30, 2011. At acquisition in April 2016 the debentures were recorded at fair value of $11.8 million, with the discount being accreted to interest expense over the remaining life of the debentures. At June 30, 2017, the carrying value of these junior debentures was $12.1 million. As part of the 2017 acquisition of First Menasha, the Company assumed $5.2 million of junior subordinated debentures related to $5.0 million of issued trust preferred securities. The trust preferred securities and the debentures mature on March 17, 2034 and have a floating rate of three-month LIBOR plus 2.79% adjusted quarterly. Interest on these debentures is current. The interest rate was 4.06% as of June 30, 2017. The debentures may be redeemed on any interest payment date at par in part or in full, on any interest payment date. At acquisition in April 2017 the debentures were recorded at fair value of $4.4 million, with the discount being accreted to interest expense over the remaining life of the debentures. At June 30, 2017, the carrying value of these junior debentures was $4.4 million. The debentures represent the sole asset of the respective statutory trusts. The statutory trusts are not included in the consolidated financial statements. The net effect of all the documents entered into with respect to the trust preferred securities is that the Company, through payment on its debentures, is liable for the distributions and other payments required on the trust preferred securities.

Subordinated Debt [Abstract]
Subordinated Notes	Note 10 – Subordinated Notes In 2015 the Company placed an aggregate of $12 million in subordinated Notes in private placements with certain accredited investors. All Notes were issued with 10-year maturities, have a fixed annual interest rate of 5% payable quarterly, are callable on or after the fifth anniversary of their respective issuances dates, and qualify for Tier 2 capital for regulatory purposes. At June 30, 2017, the carrying value of these subordinated notes was $11.9 million. The $180,000 debt issuance costs associated with the $12 million Notes are being amortized on a straight line basis over the first five years, representing the no-call periods, as additional interest expense. As of June 30, 2017 and December 31, 2016, respectively, $97,000 and $115,000, of unamortized debt issuance costs remain and are reflected as a deduction to the carrying value of the outstanding debt.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 11 – Fair Value Measurements Fair value represents the estimated price at which an orderly transaction to sell an asset or transfer a liability would take place between market participants at the measurement date under current market conditions (i.e. an exit price concept), and is a market-based measurement versus an entity-specific measurement. As provided for by accounting standards, the Company records and/or discloses financial instruments on a fair value basis. These financial assets and financial liabilities are measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the observability of the assumptions used to determine fair value. These levels are: Level 1 - quoted market prices in active markets for identical assets or liabilities that a company has the ability to access at the measurement date; Level 2 - inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly; Level 3 – significant unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the fair value measurement is based on inputs from different levels, the level within which the entire fair value measurement will be categorized is based on the lowest level input that is significant to the fair value measurement in its entirety; this assessment of the significance of an input requires management judgment. Disclosure of the fair value of financial instruments, whether recognized or not recognized in the balance sheet, is required for those instruments for which it is practicable to estimate that value, with the exception of certain financial instruments and all nonfinancial instruments as provided for by the accounting standards. For financial instruments recognized at fair value in the consolidated balance sheets, the fair value disclosure requirements also apply. Recurring basis fair value measurements: The following table presents the balances of assets and liabilities measured at fair value on a recurring basis for the periods presented. During 2017, three securities classified as Level 3 were acquired with the First Menasha acquisition in the second quarter of 2017 with a fair value of $0.2 million, and two securities classified as Level 3 had a change in fair values during the second quarter of 2017 due to pay downs.

Where quoted market prices on securities exchanges are available, the investment is classified as Level 1. Level 1 investments primarily include exchange-traded equity securities available for sale. If quoted market prices are not available, fair value is generally determined using prices obtained from independent pricing vendors who use pricing models (with typical inputs including benchmark yields, reported trades for similar securities, issuer spreads or relationship to other benchmark quoted securities), or discounted cash flows, and are classified as Level 2. Examples of these investments include mortgage-related securities and obligations of state, county and municipals. Finally, in certain cases where there is limited activity or less transparency around inputs to the estimated fair value, investments are classified within Level 3 of the hierarchy. Examples of these include private municipal bonds and corporate debt securities, which include trust preferred security investments. At June 30, 2017 and December 31, 2016, it was determined that carrying value was the best approximation of fair value for all of the Level 3 securities, based primarily on the internal analysis on these securities. Nonrecurring basis fair value measurements: The following table presents the Company’s impaired loans and other real estate owned (“OREO”) measured at fair value on a nonrecurring basis for the periods presented.

For individually evaluated impaired loans, the amount of impairment is based upon the present value of expected future cash flows discounted at the loan’s effective interest rate, the estimated fair value of the underlying collateral for collateral-dependent loans, or the estimated liquidity of the note. For OREO, the fair value is based upon the estimated fair value of the underlying collateral adjusted for the expected costs to sell.

Accounting Policies [Abstract]
General	General In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly Nicolet Bankshares, Inc. (the “Company”) and its subsidiaries, consolidated balance sheets, statements of income, comprehensive income, changes in stockholders’ equity and cash flows for the periods presented, and all such adjustments are of a normal recurring nature. All material intercompany transactions and balances are eliminated. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the entire year. These interim consolidated financial statements have been prepared according to the rules and regulations of the Securities and Exchange Commission and, therefore, certain information and footnote disclosures normally presented in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) have been omitted or abbreviated. These consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016.
Critical Accounting Policies and Estimates	Critical Accounting Policies and Estimates Preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying disclosures. These estimates are based on management’s best knowledge of current events and actions the Company may undertake in the future. Estimates are used in accounting for, among other items, the allowance for loan losses, useful lives for depreciation and amortization, fair value of financial instruments, deferred tax assets, uncertain income tax positions and contingencies. Estimates that are particularly susceptible to significant change for the Company include the determination of the allowance for loan losses, the assessment of deferred tax assets and liabilities, and the valuation of loans acquired in acquisitions; therefore, these are critical accounting policies. Factors that may cause sensitivity to the aforementioned estimates include but are not limited to: external market factors such as market interest rates and employment rates, changes to operating policies and procedures, changes in applicable banking regulations, and changes to deferred tax estimates. Actual results may ultimately differ from estimates, although management does not generally believe such differences would materially affect the consolidated financial statements in any individual reporting period presented. There have been no material changes or developments with respect to the assumptions or methodologies that the Company uses when applying what management believes are critical accounting policies and developing critical accounting estimates as disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016.
Recent Accounting Developments Adopted	Recent Accounting Developments Adopted In December 2016, the Financial Accounting Standards Board (“FASB”) issued updated guidance to Accounting Standards Update (“ASU”) 2016-19 Technical Corrections and Improvements In March 2016, the FASB issued updated guidance to ASU 2016-09: Stock Compensation Improvements to Employee Share-Based Payment Activity
Operating Segment	Operating Segment While the chief decision makers monitor the revenue streams of the various products and services, and evaluate costs, balance sheet positions and quality, all such products, services and activities are directly or indirectly related to the business of community banking, with no regular, formal or material segment delineations. Operations are managed and financial performance is evaluated on a company-wide basis, and accordingly, all the financial service operations are considered by management to be aggregated in one reportable operating segment.

When computing earnings per share for an interim period, the denominator is based on the weighted-average shares outstanding during the interim period, and not on an annualized weighted-average basis. Accordingly, the sum of the quarters' earnings per share data will not necessarily equal the year to date earnings per share data.

[1]	Cumulative quarterly per share performance may not equal annual per share totals due to the effects of the amount and timing of capital increases. When computing earnings per share for an interim period, the denominator is based on the weighted-average shares outstanding during the interim period, and not on an annualized weighted-average basis. Accordingly, the sum of the quarters' earnings per share data will not necessarily equal the year to date earnings per share data.
