BREAKING DOWN 'Net Interest Margin'

For example, ABC Corp has a return on investment of $1,000,000, an interest expense of $2,000,000 and average earning assets of $10,000,000. ABC Corp's net interest margin would be -10%. This would mean that ABC Corp has lost more money due to interest expenses than was earned from investments. In this case, ABC Corp would have been better off if it had used the investment funds to pay off debts instead to making an investment.
