Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Critical Accounting Policies	Basis of Presentation and Critical Accounting Policies Organization and Nature of business - First Northwest Bancorp, a Washington corporation, became the holding company of First Federal Savings and Loan Association of Port Angeles on January 29, 2015, upon completion of the Bank's conversion from a mutual to stock form of organization (the "Conversion"). In connection with the Conversion, the Company issued an aggregate of 12,167,000 shares of common stock at an offering price of $10.00 per share for gross proceeds of $121.7 million . An additional 933,360 shares of Company common stock and $400,000 in cash were contributed to the First Federal Community Foundation ("Foundation"), a charitable foundation that was established in connection with the Conversion, resulting in the issuance of a total of 13,100,360 shares. The Company received $117.6 million in net proceeds from the stock offering of which $58.4 million were contributed to the Bank upon Conversion. Pursuant to the Bank's Plan of Conversion (the "Plan") adopted by its Board of Directors, and as approved by its members, the Company established an employee stock ownership plan ("ESOP"). On December 18, 2015, the ESOP completed its open market purchases, with funds borrowed from the Company, of 8% of the common stock issued in the Conversion for a total of 1,048,029 shares. First Northwest's business activities generally are limited to passive investment activities and oversight of its investment in First Federal. Accordingly, the information set forth in this report, including the consolidated unaudited financial statements and related data, relates primarily to the Bank. The Bank is a community-oriented financial institution providing commercial and consumer banking services to individuals and businesses in Western Washington State with offices in Clallam, Jefferson, Kitsap, and Whatcom counties. These services include deposit and lending transactions that are supplemented with borrowing and investing activities. Basis of presentation - The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and footnotes required by U.S. Generally Accepted Accounting Principles ("GAAP") for complete financial statements. These unaudited interim consolidated financial statements should be read in conjunction with our audited consolidated financial statements and accompanying notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2018 . In our opinion, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation of the consolidated financial statements in accordance with GAAP have been included. The Company changed its fiscal year from June 30 to December 31 effective December 31, 2017. Operating results for the three months ended March 31, 2019 , are not necessarily indicative of the results that may be expected for future periods. In preparing the unaudited interim consolidated financial statements, we are required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to a determination of the allowance for loan losses ("ALLL"), fair value of financial instruments, and deferred tax assets and liabilities. Principles of consolidation - The accompanying consolidated financial statements include the accounts of First Northwest Bancorp and its wholly owned subsidiary, First Federal. All material intercompany accounts and transactions have been eliminated in consolidation. Subsequent Events - The Company has evaluated subsequent events for potential recognition and disclosure and determined there are no such events or transactions requiring recognition or disclosure. Recently adopted accounting pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases . ASU 2016-02 is intended to increase transparency and comparability among organizations by requiring the recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements. The ASU requires a lessee to recognize on the balance sheet assets and liabilities for leases with lease terms of more than 12 months. Consistent with current GAAP, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. Unlike current GAAP, which requires that only capital leases be recognized on the balance sheet, the ASC requires that both types of leases by recognized on the balance sheet. For public companies, this update is effective for interim and annual periods beginning after December 15, 2018. The adoption of ASU No. 2016-02 effective January 1, 2019 resulted in a right-of-use asset and corresponding lease obligation liability of $3,919,000 . The Corporation chose the effective date as the date of initial application. Consequently, prior period financial information has not been updated or restated. The right-of-use asset is included in other assets and the lease obligation liability is included in other liabilities on the March 31, 2019 , consolidated balance sheet. In August 2017, FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815). This ASU was issued to provide investors better insight to an entity’s risk management hedging strategies by permitting companies to recognize the economic results of its hedging strategies in its financial statements. The amendments in this ASU permit hedge accounting for hedging relationships involving non-financial risk and interest rate risk by removing certain limitations in cash flow and fair value hedging relationships. In addition, the ASU requires an entity to present the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedged item is reported. This ASU is effective for fiscal years beginning after December 15, 2018, and early adoption is permitted. Adoption of ASU 2017-12 did not have a material impact on the Company’s consolidated financial statements. In June 2018, FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting . These amendments provide specific guidance for transactions for acquiring goods and services from nonemployees and specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (i) financing to the issuer or (ii) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers . This guidance is effective for fiscal years beginning after December 15, 2018, and interim periods beginning after December 15, 2020. Early adoption is permitted but not earlier than the adoption of Topic 606. Adoption of this ASU did not have a material effect on the Company's consolidated financial statements as it has not historically issued share-based payments in exchange for goods or services to be consumed within its operations. In July 2018, FASB issued ASU No. 2018-09, Codification Improvements . These amendments provide clarifications and corrections to certain ASC subtopics including the following: 220-10 (Income Statement - Reporting Comprehensive Income - Overall), 470-50 (Debt - Modifications and Extinguishments), 480-10 (Distinguishing Liabilities from Equity - Overall), 718-740 (Compensation - Stock Compensation - Income Taxes), 805-740 (Business Combinations - Income Taxes), 815-10 (Derivatives and Hedging - Overall), and 820-10 (Fair Value Measurement - Overall). Some of the amendments in ASU 2018-09 do not require transition guidance and will be effective upon issuance; however, many of the amendments do have transition guidance with effective dates for annual periods beginning after December 15, 2018. Adoption of ASU 2018-09 did not have a material impact on the Company's consolidated financial statements. In October 2018, the FASB issued ASU No. 2018-16 Derivatives and Hedging (Topic 815), Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes . The amendments in this ASU permit use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to the interest rates on direct Treasury obligations of the U.S. government, the London Interbank Offered Rate (LIBOR) swap rate, the Overnight Index Swap (OIS) Rate based on the Fed Funds Effective Rate and the Securities Industry and Financial Markets Association (SIFMA) Municipal Swap Rate. The amendments in this ASU are required to be adopted concurrently with the amendments in ASU 2017-12. For public companies, this would be for fiscal years, and interim periods within those fiscal years beginning after December 15, 2018. Adoption of ASU 2018-16 did not have a material impact on the Company's consolidated financial statements. Recently adopted regulatory rule In August 2018, the Securities and Exchange Commission issued a final rule that amends certain of its disclosure requirements. The rule simplifies various disclosure requirements for public companies including primarily that it (i) eliminates the requirement for public companies to disclose in their filings a schedule of earnings to fixed charges, (ii) requires an analysis of changes in stockholders’ equity for the current and comparative year-to-date interim periods in interim reports, and (iii) reduces the requirements for market price information disclosures in annual reports. These changes are effective for public companies beginning on November 5, 2018. The Company will be complying with these new requirements beginning with the Quarterly Report for the period ended March 31, 2019, on Form 10-Q. Recently issued accounting pronouncements In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Loss , which updates the guidance on recognition and measurement of credit losses for financial assets. The new requirements, known as the current expected credit loss model (CECL) will require entities to adopt an impairment model based on expected losses rather than incurred losses. ASU No. 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Upon adoption, the Company will change processes and procedures to calculate the allowance for loan losses, including changes in assumptions and estimates to consider expected credit losses over the life of the loan versus the current accounting practice that utilizes the incurred loss model. In addition, the current accounting policy and procedures for other-than-temporary impairment on investment securities available for sale will be replaced with an allowance approach. At this time, we cannot reasonably estimate the impact the implementation of this ASU will have on the Company's consolidated financial statements. The Company's internal project management team continues to review models, work with our third-party vendor, and discuss changes to processes and procedures to ensure the Company is fully compliant with the amendments at the adoption date. In August 2018, FASB issued ASU No. 2018-13, Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement which removes, modifies, and adds certain disclosure requirements related to fair value measurements in ASC 820. This guidance eliminates certain disclosure requirements for fair value measurements: the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, an entity’s policy for the timing of transfers between levels of the fair value hierarchy and an entity’s valuation processes for Level 3 fair value measurements. This guidance also adds new disclosure requirements for public entities: changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements of instruments held at the end of the reporting period, and the range and weighted average of significant unobservable inputs used to develop recurring and nonrecurring Level 3 fair value measurements, including how the weighted average is calculated. Furthermore, this guidance modifies certain requirements which will involve disclosing: transfers into and out of Level 3 of the fair value hierarchy, purchases and issuances of Level 3 assets and liabilities, and information about the measurement uncertainty of Level 3 fair value measurements as of the reporting date. This guidance is effective for public companies in fiscal years beginning after December 15, 2019, with early adoption permitted. This ASU is not expected to have a material impact on the Company's consolidated financial statements. In August 2018, FASB issued ASU No. 2018-15 Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract to provide guidance on implementation costs incurred in a cloud computing arrangement that is a service contract. The ASU aligns the accounting for such costs with the guidance on capitalizing costs associated with developing or obtaining internal-use software. Specifically, the ASU amends ASC 350 to include in its scope implementation costs of such arrangements that are service contracts and clarifies that a customer should apply ASC 350-40 to determine which implementation costs should be capitalized. This ASU, which is effective for fiscal years beginning after December 15, 2019, is not expected to have a material impact on the Company’s financial statements. Reclassifications - Certain amounts in the unaudited interim consolidated financial statements for prior periods have been reclassified to conform to the current unaudited financial statement presentation with no effect on net income or shareholders' equity.

At March 31, 2019 and December 31, 2018 , there were 59 and 69 investment securities in an unrealized loss position, respectively. We believe that the unrealized losses on our investment securities relate principally to the general change in interest rates and market demand, and not credit quality, that has occurred since the initial purchase, and such unrecognized losses or gains will continue to vary with general interest rate level fluctuations in the future. Certain investments in a loss position are guaranteed by government entities or government sponsored entities. The Company does not intend to sell the securities in an unrealized loss position and believes it is not likely it will be required to sell these investments prior to a market price recovery or maturity. There were no OTTI losses during the three months ended March 31, 2019 and 2018 . The amortized cost and estimated fair value of investment securities by contractual maturity are shown in the following tables at the dates indicated. Expected maturities of mortgage-backed securities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties; therefore, these securities are shown separately.

The Company maintains a general allowance for loan losses based on evaluating known and inherent risks in the loan portfolio, including management’s continuing analysis of the factors underlying the quality of the loan portfolio. These factors include changes in the size and composition of the loan portfolio, actual loan loss experience, and current and anticipated economic conditions. The reserve is an estimate based upon factors and trends identified by management at the time the financial statements are prepared.

A loan is considered impaired when First Federal has determined that it may be unable to collect payments of principal or interest when due under the contractual terms of the loan. In the process of identifying loans as impaired, management takes into consideration factors that include payment history and status, collateral value, financial condition of the borrower, and the probability of collecting scheduled payments in the future. Minor payment delays and insignificant payment shortfalls typically do not result in a loan being classified as impaired. The significance of payment delays and shortfalls is considered by management on a case-by-case basis after taking into consideration the totality of circumstances surrounding the loans and the borrowers, including payment history and amounts of any payment shortfall, length and reason for delay, and likelihood of return to stable performance. Impairment is measured on a loan-by-loan basis for all loans in the portfolio except smaller balance homogeneous loans and certain qualifying troubled debt restructuring ("TDR") loans.

Federal regulations provide for the classification of lower quality loans and other assets, such as debt and equity securities, as substandard, doubtful, or loss; risk ratings 6, 7, and 8 in our 8-point risk rating system, respectively. An asset is considered substandard if it is inadequately protected by the current net worth and pay capacity of the borrower or of any collateral pledged. Substandard assets include those characterized by the distinct possibility that First Federal will sustain some loss if the deficiencies are not corrected. Assets classified as doubtful have all the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses present make collection or liquidation in full highly questionable and improbable, on the basis of currently existing facts, conditions, and values. Assets classified as loss are those considered uncollectible and of such little value that their continuance as assets without the establishment of a specific loss reserve is not warranted. When First Federal classifies problem assets as either substandard or doubtful, it may establish a specific allowance to address the risk specifically or allow the loss to be addressed in the general allowance. General allowances represent loss allowances that have been established to recognize the inherent risk associated with lending activities but that, unlike specific allowances, have not been specifically allocated to particular problem assets. When an insured institution classifies problem assets as a loss, it is required to charge off such assets in the period in which they are deemed uncollectible. Assets that do not currently expose First Federal to sufficient risk to warrant classification as substandard or doubtful but do possess identified weaknesses are designated as either watch or special mention assets; risk ratings 4 and 5 in our risk rating system, respectively.

A TDR is a loan to a borrower who is experiencing financial difficulty that has been modified from its original terms and conditions in such a way that First Federal is granting the borrower a concession of some kind. First Federal has granted a variety of concessions to borrowers in the form of loan modifications. The modifications are generally related to the loan's interest rate, term and payment amount or a combination thereof. Upon identifying a receivable as a TDR loan, First Federal classifies the loan as impaired for purposes of determining the allowance for loan losses. This requires the loan to initially be evaluated individually for impairment, generally based on the expected cash flows under the new terms discounted at the loan’s original effective interest rates. For TDR loans that subsequently default, the method of determining impairment is generally the fair value of the collateral less estimated selling costs. TDR loans may be upgraded in their classification and placed on accrual status once there is a sustained period of repayment performance, usually six months or longer, and there is a reasonable assurance that repayment will continue. First Federal allows reclassification of a troubled debt restructuring back into the general loan pool (as a non-troubled debt restructuring) if the borrower is able to refinance the loan at then-current market rates and meet all of the underwriting criteria of First Federal required of other borrowers. The refinance must be based on the borrower’s ability to repay the debt and no special concessions of rate and/or term are granted to the borrower.

Federal Taxes on Income

Federal Taxes on Income	3 Months Ended

Income Tax Disclosure [Abstract]
Federal Taxes on Income	Federal Taxes on Income Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. These calculations are based on many complex factors including estimates of the timing of reversals of temporary differences, the interpretation of federal income tax laws, and a determination of the differences between the tax and the financial reporting basis of assets and liabilities. Actual results could differ significantly from the estimates and interpretations used in determining the current and deferred income tax assets and liabilities. Under current Federal income tax regulations, charitable contribution deductions are limited to 10% of taxable income. Due to this limitation, the Company currently has a valuation allowance of $1.2 million for financial statement reporting purposes related to its contribution to the Foundation. The contribution carryforward and related valuation allowance will expire in 2020. A valuation allowance is provided when it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company evaluates whether its deferred tax assets will be realized and adjusts the amount of its valuation allowance, if necessary. Effective January 1, 2018, the corporate U.S. statutory federal income tax rate was reduced from 35% to 21% under the Tax Cuts and Jobs Act. The Company completed its accounting under ASC 740 in December 2017 for all material deferred tax assets and liabilities with provisional amounts recorded for immaterial items. The effective tax rates were 18.7% and 18.5% for the three months ended March 31, 2019 and 2018 , respectively. The effective tax rates differ from the statutory maximum federal tax rate for 2018 and 2017 of 21% and 35%, respectively, largely due to the nontaxable earnings on bank owned life insurance and tax-exempt interest income earned on certain investment securities and loans.

Earnings Per Share [Abstract]
Earnings per Share	Earnings per Share Basic earnings per share is computed by dividing income available to common shareholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. In addition, nonvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents are considered participating securities and are included in the computation of earnings per share. The following table presents a reconciliation of the components used to compute basic and diluted earnings per share for the three months ended March 31, 2019 and 2018 . Three Months Ended March 31, 2019 2018 (In thousands, except share data) Numerator: Net income $ 2,207 $ 1,523 Denominator: Basic weighted average common shares outstanding 9,973,125 10,491,647 Dilutive restricted stock grants 77,143 113,009 Diluted weighted average common shares outstanding 10,050,268 10,604,656 Basic earnings per share $ 0.22 $ 0.15 Diluted earnings per share $ 0.22 $ 0.14 Unallocated ESOP shares are not included as outstanding for either basic or diluted earnings per share calculations. As of March 31, 2019 and 2018 , there were 833,782 and 886,671 shares in the ESOP that remain unallocated, respectively. Potential dilutive shares are excluded from the computation of EPS if their effect is anti-dilutive. There were no restricted stock award anti-dilutive shares at March 31, 2019 and 2018 , respectively.

Employee Benefits	Employee Benefits Employee Stock Ownership Plan In connection with the Conversion, the Company established an ESOP for eligible employees of the Company and the Bank. Employees of the Company and the Bank who have been credited with at least 1,000 hours of service during a 12 -month period are eligible to participate in the ESOP. Pursuant to the Plan, the ESOP purchased shares in the open market with funds borrowed from First Northwest. The Bank will make contributions to the ESOP in amounts necessary to amortize the ESOP loan payable to First Northwest over a period of 20 years, bearing estimated interest at 2.46% . The loan is secured by shares purchased with the loan proceeds and will be repaid by the ESOP with funds from the Bank's discretionary contributions to the ESOP and earnings on the ESOP assets. As shares are committed to be released from collateral, the Company reports compensation expense equal to the average daily market prices of the shares and the shares become outstanding for EPS computations. The compensation expense is accrued monthly throughout the year. Dividends on allocated ESOP shares are recorded as a reduction of retained earnings; dividends on unallocated ESOP shares are recorded as a reduction of debt and accrued interest. Compensation expense related to the ESOP for the three months ended March 31, 2019 and 2018 , was $207,000 and $220,000 , respectively. Shares issued to the ESOP as of the dates indicated are as follows: March 31, 2019 December 31, 2018 (Dollars in thousands) Allocated shares 174,584 174,584 Committed to be released shares 39,663 26,442 Unallocated shares 833,782 847,003 Total ESOP shares issued 1,048,029 1,048,029 Fair value of unallocated shares $ 12,982 $ 12,561 Stock-based Compensation On November 16, 2015 , the Company's shareholders approved the First Northwest Bancorp 2015 Equity Incentive Plan (the "2015 EIP"), which provides for the grant of incentive stock options, non-qualified stock options, restricted stock and restricted stock units to eligible participants.

Fair Value Accounting and Measu

Fair Value Accounting and Measurement	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Accounting and Measurement	Fair Value Accounting and Measurement Fair value is the price to sell an asset or transfer a liability in an orderly transaction between market participants in the Company’s principal market. The Company has established and documented its process for determining the fair values of its assets and liabilities, where applicable. Fair value is based on quoted market prices, when available, for identical or similar assets or liabilities. In the absence of quoted market prices, management determines the fair value of the Company’s assets and liabilities using valuation models or third-party pricing services, both of which rely on market-based parameters when available, such as interest rate yield curves, option volatilities and credit spreads, or unobservable inputs. Unobservable inputs may be based on management’s judgment, assumptions, and estimates related to credit quality, liquidity, interest rates, and other relevant inputs. Any changes to valuation methodologies are reviewed by management to ensure they are relevant and justified. Valuation methodologies are refined as more market-based data becomes available. A three-level valuation hierarchy is used in determining fair value that is based on the transparency of the inputs used in the valuation process. The inputs used in determining fair value in each of the three levels of the hierarchy are as follows: Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 - Either: (i) quoted prices for similar assets or liabilities; (ii) observable inputs, such as interest rates or yield curves; or (iii) inputs derived principally from or corroborated by observable market data. Level 3 - Unobservable inputs. The hierarchy gives the highest ranking to Level 1 inputs and the lowest ranking to Level 3 inputs. The level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the overall fair value measurement. Qualitative disclosures of valuation techniques - Securities available for sale: where quoted prices are available in an active market, securities are classified as Level 1. Level 1 instruments include highly liquid government bonds, securities issued by the U.S. Treasury, and exchange-traded equity securities. If quoted prices are not available, management determines fair value using pricing models, quoted prices of similar securities, which are considered Level 2, or discounted cash flows. In certain cases, where there is limited activity in the market for a particular instrument, assumptions must be made to determine their fair value. Such instruments are classified as Level 3. Assets and liabilities measured at fair value on a recurring basis - Assets and liabilities are considered to be fair valued on a recurring basis if fair value is measured regularly (i.e., daily, weekly, monthly, or quarterly). The following tables show the Company’s assets measured at fair value on a recurring basis at the dates indicated: March 31, 2019 Quoted Prices in Active Markets for Identical Assets or Liabilities Significant Other Observable Inputs Significant Unobservable Inputs (Level 1) (Level 2) (Level 3) Total (In thousands) Securities available-for-sale Municipal bonds $ — $ 912 $ — $ 912 ABS agency — 25,719 — 25,719 ABS corporate — 37,074 — 37,074 Corporate debt — 9,494 — 9,494 SBA — 33,396 — 33,396 MBS agency — 141,527 — 141,527 MBS corporate — 10,354 — 10,354 $ — $ 258,476 $ — $ 258,476 December 31, 2018 Quoted Prices in Active Markets for Identical Assets or Liabilities Significant Other Observable Inputs Significant Unobservable Inputs (Level 1) (Level 2) (Level 3) Total (In thousands) Securities available-for-sale Municipal bonds $ — $ 869 $ — $ 869 ABS agency — 25,752 — 25,752 ABS corporate — 36,723 — 36,723 Corporate debt — 9,888 — 9,888 SBA — 35,670 — 35,670 MBS agency — 143,455 — 143,455 MBS corporate — 10,610 — 10,610 $ — $ 262,967 $ — $ 262,967 Assets and liabilities measured at fair value on a nonrecurring basis - Assets are considered to be fair valued on a nonrecurring basis if the fair value measurement of the instrument does not necessarily result in a change in the amount recorded on the consolidated balance sheets. Generally, nonrecurring valuation is the result of the application of other accounting pronouncements that require assets or liabilities to be assessed for impairment or recorded at the lower of cost or fair value.

Estimated fair values require subjective judgments and are approximate. The estimates of fair value in the previous table are not necessarily representative of amounts that could be realized in actual market transactions, or of the underlying value of the Company. The methods and assumptions used by the Company in estimating fair values of financial instruments as set forth below in accordance with ASC Topic 825, Financial Instruments , as amended by ASU 2016-01 requiring public entities to use the exit price notion effective January 1, 2018, are as follows: Securities - Fair values for investment securities are primarily measured using information from a third-party pricing service. The pricing service uses pricing models based on market data. In the event that limited or less transparent information is provided by the third-party pricing service, fair value is estimated using secondary pricing services or non-binding third-party broker quotes. Loans receivable, net - At March 31, 2019 , the fair value of loans is estimated by discounting the future cash flows using the current rate at which similar loans and leases would be made to borrowers with similar credit and for the same remaining maturities. Additionally, to be consistent with the requirements under FASB ASC Topic 820 for Fair Value Measurements and Disclosures, the loans were valued at a price that represents the Company’s exit price or the price at which these instruments would be sold or transferred. Mortgage servicing rights, net - The estimated fair value of mortgage servicing rights is based on market prices for comparable mortgage servicing contracts when available. If no comparable contract is available, the estimated fair value is based on a valuation model that calculates the present value of estimated future net servicing income.

Revenue from Contract with Customer [Abstract]
Noninterest Income	Noninterest Income On January 1, 2018, the Company adopted the amendments of ASU 2014-09 Revenue from Contracts with Customers (Topic 606) and all subsequent ASUs that modified Topic 606. The Company has included the following table regarding the Company’s noninterest income for the periods presented. Three Months Ended March 31, 2019 2018 (In thousands) Noninterest income: Loan fees (1) $ 239 $ 125 Deposit fees 447 392 Debit interchange income 22 32 Credit card interchange income 402 406 Investment securities gain (loss), net (1) — 122 Gain on loan sales, net (1) 87 167 Increase in cash surrender value of BOLI (1) 143 149 Other income: Investment services revenue 48 74 Gain or loss on subsidiary (1) 14 14 Remaining other income 9 1 Total other income 71 89 Total noninterest income $ 1,411 $ 1,482 (1) Not within scope of Topic 606 The Company recognizes revenue as it is earned and noted no impact to its revenue recognition policies as a result of the adoption of ASU 2014-09. The following is a discussion of key revenues within the scope of the new revenue guidance. Deposit fees - The Company earns fees from its deposit customers for account maintenance, transaction-based activity and overdraft services. Account maintenance fees consist primarily of account fees and analyzed account fees charged on deposit accounts on a monthly basis. The performance obligation is satisfied and the fees are recognized on a monthly basis as the service period is completed. Transaction-based fees on deposit accounts are charged to deposit customers for specific services provided to the customer, such as non-sufficient funds fees, overdraft fees, and wire fees. The performance obligation is completed as the transaction occurs and the fees are recognized at the time each specific service is provided to the customer. Debit interchange income - Debit and Automated Teller Machine ("ATM") interchange income represent fees earned when a debit card issued by the Company is used. The Company earns interchange fees from debit cardholder transactions through card networks. In addition, the Company earns interchange fees for use of its ATM by customers of other banking institutions. Interchange fees are based on purchase volumes and other factors and are recognized as transactions occur. The performance obligation is satisfied and the fees are earned when the cost of the transaction is charged to the cardholder's debit card. Certain expenses directly associated with the credit and debit card are netted against interchange income. Credit card interchange income - Credit card interchange income represents fees earned when a credit card issued by the Bank through a third-party vendor is used. Similar to the debit card interchange, the Bank earns an interchange fee for each transaction made with a Bank-branded credit card. The performance obligation is satisfied and the fees are earned when the cost of the transaction is charged to the cardholder's credit card. Certain expenses directly related to the credit card interchange contract are netted against interchange income. Investment services revenue - Commissions received on the sale of investment related products is determined by a percentage of underlying instruments sold and is recognized when the sale is finalized. Sale of other real estate owned (OREO) - Gains/losses on the sale of OREO are included in non-interest expense and are generally recognized when the performance obligation is complete. This is typically at delivery of control over the property to the buyer at time of each real estate closing.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of presentation - The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and footnotes required by U.S. Generally Accepted Accounting Principles ("GAAP") for complete financial statements. These unaudited interim consolidated financial statements should be read in conjunction with our audited consolidated financial statements and accompanying notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2018 . In our opinion, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation of the consolidated financial statements in accordance with GAAP have been included. The Company changed its fiscal year from June 30 to December 31 effective December 31, 2017. Operating results for the three months ended March 31, 2019 , are not necessarily indicative of the results that may be expected for future periods. In preparing the unaudited interim consolidated financial statements, we are required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to a determination of the allowance for loan losses ("ALLL"), fair value of financial instruments, and deferred tax assets and liabilities.
Principles of Consolidation	Principles of consolidation - The accompanying consolidated financial statements include the accounts of First Northwest Bancorp and its wholly owned subsidiary, First Federal. All material intercompany accounts and transactions have been eliminated in consolidation.
Subsequent Events	Subsequent Events - The Company has evaluated subsequent events for potential recognition and disclosure and determined there are no such events or transactions requiring recognition or disclosure.
Recently Adopted Accounting Policies, Regulatory Rule and Issued Accounting Pronouncements	Recently adopted accounting pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases . ASU 2016-02 is intended to increase transparency and comparability among organizations by requiring the recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements. The ASU requires a lessee to recognize on the balance sheet assets and liabilities for leases with lease terms of more than 12 months. Consistent with current GAAP, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. Unlike current GAAP, which requires that only capital leases be recognized on the balance sheet, the ASC requires that both types of leases by recognized on the balance sheet. For public companies, this update is effective for interim and annual periods beginning after December 15, 2018. The adoption of ASU No. 2016-02 effective January 1, 2019 resulted in a right-of-use asset and corresponding lease obligation liability of $3,919,000 . The Corporation chose the effective date as the date of initial application. Consequently, prior period financial information has not been updated or restated. The right-of-use asset is included in other assets and the lease obligation liability is included in other liabilities on the March 31, 2019 , consolidated balance sheet. In August 2017, FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815). This ASU was issued to provide investors better insight to an entity’s risk management hedging strategies by permitting companies to recognize the economic results of its hedging strategies in its financial statements. The amendments in this ASU permit hedge accounting for hedging relationships involving non-financial risk and interest rate risk by removing certain limitations in cash flow and fair value hedging relationships. In addition, the ASU requires an entity to present the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedged item is reported. This ASU is effective for fiscal years beginning after December 15, 2018, and early adoption is permitted. Adoption of ASU 2017-12 did not have a material impact on the Company’s consolidated financial statements. In June 2018, FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting . These amendments provide specific guidance for transactions for acquiring goods and services from nonemployees and specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (i) financing to the issuer or (ii) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers . This guidance is effective for fiscal years beginning after December 15, 2018, and interim periods beginning after December 15, 2020. Early adoption is permitted but not earlier than the adoption of Topic 606. Adoption of this ASU did not have a material effect on the Company's consolidated financial statements as it has not historically issued share-based payments in exchange for goods or services to be consumed within its operations. In July 2018, FASB issued ASU No. 2018-09, Codification Improvements . These amendments provide clarifications and corrections to certain ASC subtopics including the following: 220-10 (Income Statement - Reporting Comprehensive Income - Overall), 470-50 (Debt - Modifications and Extinguishments), 480-10 (Distinguishing Liabilities from Equity - Overall), 718-740 (Compensation - Stock Compensation - Income Taxes), 805-740 (Business Combinations - Income Taxes), 815-10 (Derivatives and Hedging - Overall), and 820-10 (Fair Value Measurement - Overall). Some of the amendments in ASU 2018-09 do not require transition guidance and will be effective upon issuance; however, many of the amendments do have transition guidance with effective dates for annual periods beginning after December 15, 2018. Adoption of ASU 2018-09 did not have a material impact on the Company's consolidated financial statements. In October 2018, the FASB issued ASU No. 2018-16 Derivatives and Hedging (Topic 815), Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes . The amendments in this ASU permit use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to the interest rates on direct Treasury obligations of the U.S. government, the London Interbank Offered Rate (LIBOR) swap rate, the Overnight Index Swap (OIS) Rate based on the Fed Funds Effective Rate and the Securities Industry and Financial Markets Association (SIFMA) Municipal Swap Rate. The amendments in this ASU are required to be adopted concurrently with the amendments in ASU 2017-12. For public companies, this would be for fiscal years, and interim periods within those fiscal years beginning after December 15, 2018. Adoption of ASU 2018-16 did not have a material impact on the Company's consolidated financial statements. Recently adopted regulatory rule In August 2018, the Securities and Exchange Commission issued a final rule that amends certain of its disclosure requirements. The rule simplifies various disclosure requirements for public companies including primarily that it (i) eliminates the requirement for public companies to disclose in their filings a schedule of earnings to fixed charges, (ii) requires an analysis of changes in stockholders’ equity for the current and comparative year-to-date interim periods in interim reports, and (iii) reduces the requirements for market price information disclosures in annual reports. These changes are effective for public companies beginning on November 5, 2018. The Company will be complying with these new requirements beginning with the Quarterly Report for the period ended March 31, 2019, on Form 10-Q. Recently issued accounting pronouncements In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Loss , which updates the guidance on recognition and measurement of credit losses for financial assets. The new requirements, known as the current expected credit loss model (CECL) will require entities to adopt an impairment model based on expected losses rather than incurred losses. ASU No. 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Upon adoption, the Company will change processes and procedures to calculate the allowance for loan losses, including changes in assumptions and estimates to consider expected credit losses over the life of the loan versus the current accounting practice that utilizes the incurred loss model. In addition, the current accounting policy and procedures for other-than-temporary impairment on investment securities available for sale will be replaced with an allowance approach. At this time, we cannot reasonably estimate the impact the implementation of this ASU will have on the Company's consolidated financial statements. The Company's internal project management team continues to review models, work with our third-party vendor, and discuss changes to processes and procedures to ensure the Company is fully compliant with the amendments at the adoption date. In August 2018, FASB issued ASU No. 2018-13, Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement which removes, modifies, and adds certain disclosure requirements related to fair value measurements in ASC 820. This guidance eliminates certain disclosure requirements for fair value measurements: the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, an entity’s policy for the timing of transfers between levels of the fair value hierarchy and an entity’s valuation processes for Level 3 fair value measurements. This guidance also adds new disclosure requirements for public entities: changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements of instruments held at the end of the reporting period, and the range and weighted average of significant unobservable inputs used to develop recurring and nonrecurring Level 3 fair value measurements, including how the weighted average is calculated. Furthermore, this guidance modifies certain requirements which will involve disclosing: transfers into and out of Level 3 of the fair value hierarchy, purchases and issuances of Level 3 assets and liabilities, and information about the measurement uncertainty of Level 3 fair value measurements as of the reporting date. This guidance is effective for public companies in fiscal years beginning after December 15, 2019, with early adoption permitted. This ASU is not expected to have a material impact on the Company's consolidated financial statements. In August 2018, FASB issued ASU No. 2018-15 Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract to provide guidance on implementation costs incurred in a cloud computing arrangement that is a service contract. The ASU aligns the accounting for such costs with the guidance on capitalizing costs associated with developing or obtaining internal-use software. Specifically, the ASU amends ASC 350 to include in its scope implementation costs of such arrangements that are service contracts and clarifies that a customer should apply ASC 350-40 to determine which implementation costs should be capitalized. This ASU, which is effective for fiscal years beginning after December 15, 2019, is not expected to have a material impact on the Company’s financial statements.
Reclassifications	Reclassifications - Certain amounts in the unaudited interim consolidated financial statements for prior periods have been reclassified to conform to the current unaudited financial statement presentation with no effect on net income or shareholders' equity.
Earnings per Share	Basic earnings per share is computed by dividing income available to common shareholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. In addition, nonvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents are considered participating securities and are included in the computation of earnings per share.
Fair Value Accounting and Measurement	Fair value is the price to sell an asset or transfer a liability in an orderly transaction between market participants in the Company’s principal market. The Company has established and documented its process for determining the fair values of its assets and liabilities, where applicable. Fair value is based on quoted market prices, when available, for identical or similar assets or liabilities. In the absence of quoted market prices, management determines the fair value of the Company’s assets and liabilities using valuation models or third-party pricing services, both of which rely on market-based parameters when available, such as interest rate yield curves, option volatilities and credit spreads, or unobservable inputs. Unobservable inputs may be based on management’s judgment, assumptions, and estimates related to credit quality, liquidity, interest rates, and other relevant inputs. Any changes to valuation methodologies are reviewed by management to ensure they are relevant and justified. Valuation methodologies are refined as more market-based data becomes available. A three-level valuation hierarchy is used in determining fair value that is based on the transparency of the inputs used in the valuation process. The inputs used in determining fair value in each of the three levels of the hierarchy are as follows: Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 - Either: (i) quoted prices for similar assets or liabilities; (ii) observable inputs, such as interest rates or yield curves; or (iii) inputs derived principally from or corroborated by observable market data. Level 3 - Unobservable inputs. The hierarchy gives the highest ranking to Level 1 inputs and the lowest ranking to Level 3 inputs. The level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the overall fair value measurement. Qualitative disclosures of valuation techniques - Securities available for sale: where quoted prices are available in an active market, securities are classified as Level 1. Level 1 instruments include highly liquid government bonds, securities issued by the U.S. Treasury, and exchange-traded equity securities. If quoted prices are not available, management determines fair value using pricing models, quoted prices of similar securities, which are considered Level 2, or discounted cash flows. In certain cases, where there is limited activity in the market for a particular instrument, assumptions must be made to determine their fair value. Such instruments are classified as Level 3. Assets and liabilities measured at fair value on a recurring basis - Assets and liabilities are considered to be fair valued on a recurring basis if fair value is measured regularly (i.e., daily, weekly, monthly, or quarterly).
Fair Value of Financial Instruments	Financial assets and liabilities other than investment securities are not traded in active markets. Estimated fair values require subjective judgments and are approximate. The estimates of fair value in the previous table are not necessarily representative of amounts that could be realized in actual market transactions, or of the underlying value of the Company. The methods and assumptions used by the Company in estimating fair values of financial instruments as set forth below in accordance with ASC Topic 825, Financial Instruments , as amended by ASU 2016-01 requiring public entities to use the exit price notion effective January 1, 2018, are as follows: Securities - Fair values for investment securities are primarily measured using information from a third-party pricing service. The pricing service uses pricing models based on market data. In the event that limited or less transparent information is provided by the third-party pricing service, fair value is estimated using secondary pricing services or non-binding third-party broker quotes. Loans receivable, net - At March 31, 2019 , the fair value of loans is estimated by discounting the future cash flows using the current rate at which similar loans and leases would be made to borrowers with similar credit and for the same remaining maturities. Additionally, to be consistent with the requirements under FASB ASC Topic 820 for Fair Value Measurements and Disclosures, the loans were valued at a price that represents the Company’s exit price or the price at which these instruments would be sold or transferred. Mortgage servicing rights, net - The estimated fair value of mortgage servicing rights is based on market prices for comparable mortgage servicing contracts when available. If no comparable contract is available, the estimated fair value is based on a valuation model that calculates the present value of estimated future net servicing income.
