T This research aims to analyze the influence of bank characteristics on bank profitability, with the dependent variable Return on Assets and the independent variables Capital Adequacy Ratio, Deposit to Asset Ratio, Loan to Asset Ratio, Loan to Deposit Ratio, Non-Performing Loan, and Bank Size. Research was also carried out on whether Non-Performing Loan can moderate the influence of Capital Adequacy Ratio on Return on Assets.The study employed secondary data obtained from open conventional banks\\\' annual financial reports that are filed with the Financial Services Authority. Purposive sampling was used to select the research sample, yielding 38 companies meeting the sample criteria. Using the Eviews program, multiple regression analysis of the data was performed to test the hypothesis. The study\\\'s findings demonstrate that Return on Assets, the dependent variable, is significantly influenced by the independent variables Deposit to Asset Ratio, Loan to Asset Ratio, Non-Performing Loan, and bank size. The study\\\'s findings support the idea that larger banks are seen as stronger and more stable by investors and customers. This helps the bank win over more business by attracting more outside capital and boosting customer confidence. To guarantee that borrowers have sufficient ability to repay loans, banks must, nevertheless, maintain a cautious credit distribution policy and conduct thorough credit analysis when dealing with large credit distributions. To lower Non-Performing Loan’s, banks must also consistently review credit performance and implement efficient payment collection strategies. Naturally, investors will find it appealing to invest when there is maximum profitability.
