Net Interest Income Calculator: Measure Bank Profitability Easily

The Net Interest Income Calculator subtracts a bank’s interest expense from its interest income to reveal core profitability. For example, $1 050 000 income minus $500 000 expense equals $550 000 NII. U.S. banks earned 69 % of their revenue from NII in 2022 (S&P Global Market Intelligence, 2023).
