Suppose a bank has the following financial data:

- Interest Expenses: $400,000
- Average Earning Assets: $20,000,000
The NIM would be calculated as follows:
Net Interest Income = Interest Income - Interest Expenses NIM = (Net Interest Income / Average Earning Assets) * 100 NIM = (($1,000,000 - $400,000) / $20,000,000) * 100 = 3%
