Questions fréquentes

What is the simple interest formula?

I = P × R × T ÷ 100, where P is principal, R is the annual rate as a percent, and T is time in years. Interest is not added to the principal - it does not compound.

How is simple interest different from compound interest?

Simple interest is always calculated on the original principal only. Compound interest is calculated on the growing balance (principal + previously-earned interest), so it grows faster over long periods.
