BANKING #6 NET INTEREST MARGIN (NIM)
Net interest margin (NIM) is a measure of the difference between interest paid and interest received, adjusted for the total amount of interest-generating assets held by the bank.
Net interest margin (NIM) reveals the amount of money that a bank is earning in interest on loans compared to the amount it is paying in interest on deposits.
NIM is one indicator of a bank’s profitability and growth.
In short, net interest margin is one indicator of a bank’s profitability and growth. It reveals how much the bank is earning in interest on its loans compared to how much it is paying out in interest on deposits.
Net interest margin is not the same as net interest income. Net interest income is the numerator in the equation for net interest margin, but the denominator is the bank’s total assets, and that can change in proportions that are not reflected in the numerator.
Net interest margin is not the same as profitability, either. Most banks also earn significant income from fees and service charges of various kinds, and those are not reflected in net interest margin.
