Interest Revenue Credit or Debit is an accounting term used to describe the resulting net interest income from a loan. When a loan is taken out, any amount of interest charged above the principal amount is credited to the account as interest income. Similarly, when a loan is repaid, any interest paid on the loan is debited from the account. In this way, net interest revenue can be calculated by subtracting any interest debited from total interest income credited. By monitoring these transactions carefully, businesses can ensure their current and future financial stability.
