Nature of Operations and Summary of Significant Account Policies
Nature of Operations	Nature of Operations Cincinnati Bancorp, Inc. (“Company”), is the savings and loan holding company for Cincinnati Federal (the “Bank”), a federally chartered stock savings and loan association that is primarily engaged in providing a full range of banking and financial services to individual and corporate customers. Our business operations are conducted in the larger Greater Cincinnati/Northern Kentucky metropolitan area which includes Hamilton, Warren, Butler and Clermont Counties in Ohio, Boone, Kenton and Campbell Counties in Kentucky, and Dearborn County, Indiana. The Company is subject to competition from other financial institutions. The Company is subject to the regulation of certain federal and state agencies and undergoes periodic examinations by those regulatory authorities.
Revenue Recognition	Revenue Recognition The Company accounts for revenues in accordance with accounting guidance that provides that an entity should recognize revenue to depict the transfer of promised goods and services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Interest income, net securities gains (losses), gains from the sale of mortgage loans and earnings on bank-owned life insurance are not covered under ASC 606 and are recognized as contractually earned. For other revenue streams including service charges on deposits and electronic banking fees, there are no significant judgments related to the amount and timing of revenue recognition. All of the Company’s revenue from contracts with customers is recognized within other noninterest income. Service charges on deposit accounts: The Company earns fees from its deposit customers for transaction-based, account maintenance and overdraft services. Transaction-based fees, which include services such as stop payment charges, statement rendering and other fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer’s account balance. Service charges are recorded in other noninterest income. Interchange income: The Company earns interchange income from cardholder transactions conducted through the various payment networks. Interchange income from cardholder transactions represent a percentage of the underlying transaction value and is recognized daily, concurrently with the transaction processing services provided to the cardholder. The gross amount of these fees is processed through noninterest income. Interchange fees are recorded in other noninterest income.
Principles of Consolidation	Principles of Consolidation The accompanying condensed consolidated financial statements as of September 30, 2022 and December 31, 2021 and for the three and nine months ended September 30, 2022 and 2021 include the accounts of the Company and the Bank. All significant intercompany items have been eliminated in consolidation.
Interim Financial Statements	Interim Financial Statements The interim condensed consolidated financial statements as of September 30, 2022, and for the three and nine months ended September 30, 2022 and 2021, are unaudited and reflect all normal recurring adjustments that are, in the opinion of management, necessary for a fair presentation of the results for the interim periods presented. Such adjustments are the only adjustments contained in these unaudited consolidated financial statements. These unaudited condensed consolidated financial statements have been prepared according to the rules and regulations of the Securities and Exchange Commission and, therefore, certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) have been omitted. The results of operations for the three and nine months ended September 30, 2022, are not necessarily indicative of the results to be achieved for the remainder of the year ending December 31, 2022, or any other period. The accompanying condensed consolidated financial statements as of September 30, 2022 and December 31, 2021 and for the three and nine months ended September 30, 2022 and 2021, should be read in conjunction with the audited consolidated financial statements as of and for the years ended December 31, 2021 and 2020 contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, loan servicing rights, lender reserve account and fair values of financial instruments.
