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, King, 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, 2019 . 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 end from June 30 to December 31 effective December 31, 2017. Operating results for the three months ended March 31, 2020 , 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 has included additional information where appropriate. Recently adopted accounting pronouncements 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 did not 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, did not have a material impact on the Company’s financial statements. In March 2020, the FASB issued ASU No. 2020-03, Codification Improvements to Financial Instruments . The amendments represent clarification and improvements to the codification and correct unintended application. This standard was effective immediately upon issuance and its adoption did not have a material effect on the Company’s financial statements. Recently issued accounting pronouncements not yet adopted Credit Losses 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. Additional updates were issued in ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging (Topic 825), Financial Instruments . This ASU clarifies and improves guidance related to the previously issued standards on credit losses, hedging and recognition and measurement of financial instruments. The amendments provide entities with various measurement alternatives and policy elections related to accounting for credit losses and accrued interest receivable balances. Entities are also able to elect a practical expedient to separately disclose the total amount of accrued interest included in the amortized cost basis as a single balance to meet certain disclosure requirements. The amendments clarify that the estimated allowance for credit losses should include all expected recoveries of financial assets and trade receivables that were previously written off and expected to be written off. The amendments also allow entities to use projections of future interest rate environments when using a discounted cash flow method to measure expected credit losses on variable-rate financial instruments. In addition, new updates were issued through ASU No. 2019-05, Financial Instruments - Credit Losses (Topic 326): Targeted Transition Relief . This amendment allows entities to elect the fair value option on certain financial instruments. On adoption, an entity is allowed to irrevocably elect the fair value option on an instrument-by-instrument basis. This alternative is available for all instruments in the scope of Subtopic 326-20 except for existing held-to-maturity debt securities. If an entity elects the fair value option, the difference between the instrument’s fair value and carrying amount is recognized as a cumulative-effect adjustment. In November 2019, the FASB issued ASU 2019-10 which defers the effective date for this guidance for smaller reporting companies from the interim and annual periods beginning after December 15, 2020 to the interim and annual periods beginning after December 15, 2022. Early adoption is permitted for interim and annual periods beginning after December 15, 2018. The Company plans to defer adoption of CECL until January 1, 2023. The Company is evaluating the provisions of ASU No. 2016-13, ASU No. 2019-04 and ASU No. 2019-05, and will closely monitor developments and additional guidance to determine the potential impact on the Company’s consolidated financial statements. At this time, we cannot reasonably estimate the impact the implementation of these ASUs 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. Other Pronouncements In December 2019, FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes . ASU 2019-12 simplifies various aspects related to accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The standard also clarifies and amends existing guidance to improve consistent application. This ASU, which is effective for fiscal years beginning after December 15, 2020, is not expected to have a material impact on the Company's financial statements. Early adoption is permitted. In January 2020, the FASB issued ASU No. 2020-01, Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)-Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 . ASU 2020-01 clarifies the interaction between accounting standards related to equity securities, equity method investments, and certain derivatives including accounting for the transition into and out of the equity method and measuring certain purchased options and forward contracts to acquire investments. The ASU, which is effective for fiscal years beginning after December 15, 2020, is not expected to have a material effect on the Company's financial statements. In March 2020, the FASB issued ASU No. 2020-04 Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting . ASU 2020-04 provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments are effective for the Company as of March 12, 2020 through December 31, 2022. The Company does not believe this standard will have a material impact on its 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, 2020 and December 31, 2019 , there were 41 and 62 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, market demand, and related volatility, rather than credit quality, that has occurred since the initial purchase, and such unrecognized losses or gains will continue to vary with general interest rate level and market 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, 2020 and 2019 . 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.

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. 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 certain 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 enough 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. Loans not otherwise classified are considered pass graded loans and are rated 1-3 in our risk rating system. Additionally, First Federal categorizes loans as performing or nonperforming based on payment activity. Loans that are more than 90 days past due and nonaccrual loans are considered nonperforming.

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.

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. The effective tax rates were 18.9% and 18.7% for the three months ended March 31, 2020 and 2019 , respectively. The effective tax rates differ from the statutory maximum federal tax rate for 2019 and 2018 of 21%, 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, 2020 and 2019 . Three Months Ended March 31, 2020 2019 (In thousands, except share data) Numerator: Net income $ 873 $ 2,207 Denominator: Basic weighted average common shares outstanding 9,624,727 9,973,125 Dilutive restricted stock grants 51,650 77,143 Diluted weighted average common shares outstanding 9,676,377 10,050,268 Basic earnings per share $ 0.09 $ 0.22 Diluted earnings per share $ 0.09 $ 0.22 Unallocated ESOP shares are not included as outstanding for either basic or diluted earnings per share calculations. As of March 31, 2020 and 2019 , there were 780,785 and 833,782 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 16,256 and zero restricted stock award anti-dilutive weighted-average shares for the three months ended March 31, 2020 and 2019 , respectively.

Share-based Payment Arrangement [Abstract]
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. No principal or interest was paid by the ESOP during the three months ended March 31, 2020 . 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, 2020 and 2019 , was $151,000 and $207,000 , respectively. Shares issued to the ESOP as of the dates indicated are as follows: March 31, 2020 December 31, 2019 (Dollars in thousands) Allocated shares 253,987 253,987 Committed to be released shares 13,257 — Unallocated shares 780,785 794,042 Total ESOP shares issued 1,048,029 1,048,029 Fair value of unallocated shares $ 8,487 $ 14,396 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. The cost of awards under the 2015 EIP generally is based on the fair value of the awards on their grant date. The maximum number of shares that may be utilized for awards under the 2015 EIP is 1,834,050 . The 2015 EIP provides for the use of authorized but unissued shares or shares that have been reacquired by First Northwest to fund share-based awards. At March 31, 2020 , there were 1,322,050 total shares available for grant under the 2015 EIP, including 12,014 shares available to be granted as restricted stock. During the three months ended March 31, 2020 , 35,100 shares of restricted stock were awarded and no stock options were granted. There were no shares of restricted stock awarded during the three and three months ended March 31, 2019 . Awarded shares of restricted stock vest ratably over five years from the date of grant provided the eligible participant remains in service to the Company. The Company recognizes compensation expense for the restricted stock awards based on the fair value of the shares at the grant date amortized over five years . For the three months ended March 31, 2020 and 2019 , total compensation expense for the 2015 EIP was $304,000 and $283,000 , respectively. Included in the above compensation expense for the three months ended March 31, 2020 and 2019 , directors' compensation was $85,000 and $85,000 , respectively.

The cost is expected to be recognized over the remaining weighted-average vesting period of approximately 3.46 years. Subsequent to quarter-end, on May 5, 2020, the Company's shareholders approved the First Northwest Bancorp 2020 Equity Incentive Plan (the "2020 EIP"), which provides for the grant of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock shares or restricted stock units, and performance share awards to eligible participants. The cost of awards under the 2020 EIP generally is based on the fair value of the awards on their grant date. The maximum number of shares that may be utilized for awards under the 2020 EIP is 520,000 . The 2020 EIP provides for the use of authorized but unissued shares or shares that have been reacquired by First Northwest to fund share-based awards. The 2020 EIP is separate from the 2015 EIP. The adoption of the 2020 EIP neither affects nor is affected by the continued existence of the 2015 EIP, except that after May 5, 2020, no further awards will be granted under the 2015 EIP.

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 an 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 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, 2020 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 $ — $ 52,254 $ — $ 52,254 ABS agency — 42,125 — 42,125 ABS corporate — 34,073 — 34,073 Corporate debt — 9,439 — 9,439 SBA — 25,363 — 25,363 MBS agency — 145,139 — 145,139 MBS corporate — 9,127 — 9,127 $ — $ 317,520 $ — $ 317,520 December 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 $ — $ 39,282 $ — $ 39,282 ABS agency — 28,858 — 28,858 ABS corporate — 40,855 — 40,855 Corporate debt — 9,643 — 9,643 SBA — 28,459 — 28,459 MBS agency — 160,167 — 160,167 MBS corporate — 8,316 — 8,316 $ — $ 315,580 $ — $ 315,580 Assets and liabilities measured at fair value on a nonrecurring basis - Assets are considered to be 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, 2020 , 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.

Subsequent Events [Abstract]
Subsequent Event	Subsequent Event As one of the first regions to experience COVID-19 infections, Washington State moved quickly to mandate business closures and implement quarantine measures. Consequently, the Company incorporated several COVID-19 pandemic measures to assist the communities we serve. We are actively assisting customers and supporting the businesses in our communities. Our loan officers are contacting borrowers who are affected by declining economic activity, offering their assistance with payment deferrals and interest only payment options. Additionally, we continue to help our small business borrowers navigate the Small Business Administration’s Paycheck Protection Program. We processed approximately $29.1 million of PPP loans for more than 377 customers in SBA PPP loan fundings as of May 7, 2020, with an average loan amount approved of approximately $77,000 . Payments by borrowers on these loans begin six months after the note date, and interest, at 1% , will continue to accrue during the six-month deferment. Loans can be forgiven in whole or part (up to full principal and any accrued interest). The success of our banking operation relies entirely on the safety and well-being of our employees and customers. On March 20, 2020, we began restricting lobby activities at all branches to appointment only and encouraged the use of drive-up services, ITM/ATM machines, digital banking applications and our contact center. On March 23, 2020, the State of Washington announced the Stay Home, Stay Healthy order for all residents, resulting in the closing of businesses or a substantial reduction in business activity. Nearly 70% of our staff are able to work remotely, and we will continue operating in this manner until the mandated Stay Home, Stay Healthy order is lifted by the State of Washington.

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, 2019 . 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 end from June 30 to December 31 effective December 31, 2017. Operating results for the three months ended March 31, 2020 , 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 has included additional information where appropriate.
Recently Adopted Accounting Policies, Regulatory Rule and Issued Accounting Pronouncements	Recently issued accounting pronouncements not yet adopted Credit Losses 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. Additional updates were issued in ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging (Topic 825), Financial Instruments . This ASU clarifies and improves guidance related to the previously issued standards on credit losses, hedging and recognition and measurement of financial instruments. The amendments provide entities with various measurement alternatives and policy elections related to accounting for credit losses and accrued interest receivable balances. Entities are also able to elect a practical expedient to separately disclose the total amount of accrued interest included in the amortized cost basis as a single balance to meet certain disclosure requirements. The amendments clarify that the estimated allowance for credit losses should include all expected recoveries of financial assets and trade receivables that were previously written off and expected to be written off. The amendments also allow entities to use projections of future interest rate environments when using a discounted cash flow method to measure expected credit losses on variable-rate financial instruments. In addition, new updates were issued through ASU No. 2019-05, Financial Instruments - Credit Losses (Topic 326): Targeted Transition Relief . This amendment allows entities to elect the fair value option on certain financial instruments. On adoption, an entity is allowed to irrevocably elect the fair value option on an instrument-by-instrument basis. This alternative is available for all instruments in the scope of Subtopic 326-20 except for existing held-to-maturity debt securities. If an entity elects the fair value option, the difference between the instrument’s fair value and carrying amount is recognized as a cumulative-effect adjustment. In November 2019, the FASB issued ASU 2019-10 which defers the effective date for this guidance for smaller reporting companies from the interim and annual periods beginning after December 15, 2020 to the interim and annual periods beginning after December 15, 2022. Early adoption is permitted for interim and annual periods beginning after December 15, 2018. The Company plans to defer adoption of CECL until January 1, 2023. The Company is evaluating the provisions of ASU No. 2016-13, ASU No. 2019-04 and ASU No. 2019-05, and will closely monitor developments and additional guidance to determine the potential impact on the Company’s consolidated financial statements. At this time, we cannot reasonably estimate the impact the implementation of these ASUs 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. Other Pronouncements In December 2019, FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes . ASU 2019-12 simplifies various aspects related to accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The standard also clarifies and amends existing guidance to improve consistent application. This ASU, which is effective for fiscal years beginning after December 15, 2020, is not expected to have a material impact on the Company's financial statements. Early adoption is permitted. In January 2020, the FASB issued ASU No. 2020-01, Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)-Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 . ASU 2020-01 clarifies the interaction between accounting standards related to equity securities, equity method investments, and certain derivatives including accounting for the transition into and out of the equity method and measuring certain purchased options and forward contracts to acquire investments. The ASU, which is effective for fiscal years beginning after December 15, 2020, is not expected to have a material effect on the Company's financial statements. In March 2020, the FASB issued ASU No. 2020-04 Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting . ASU 2020-04 provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments are effective for the Company as of March 12, 2020 through December 31, 2022. The Company does not believe this standard will have a material impact on its 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 an 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 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, 2020 , 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.
