Microsoft Excel provides functions for the calculations of many different financial transactions, including payments of principal and interest on loans and investments. Because some loans require interest-only payments, knowing how to calculate interest payments is crucial to budgeting. Type in the principal owed on your loan or the amount of your investment in the cell for Principal, B1. 2  Divide your annual interest rate by 12 if you want to calculate interest on a monthly basis; divide by 4 if quarterly interest is to be calculated. 3  Place this in cell B2.

Interest is another Latin verb hiding in plain sight. In Latin, it means âit is important,â literally âto be between,â which might help explain its early application in English for legal and business transactions. Its general association of attention and curiosity doesnât emerge until the 1770s.
