Calculate interest earned on your investment
Simple interest is calculated only on the original principal, not on previously earned interest.
The basic formula is I = P × r × t, and total amount is A = P + I.
Unlike compound interest, simple interest does not grow interest-on-interest during the period.
Use it for simple loans, short-term calculations, and educational examples where the agreement specifies simple interest.
Rates and time must use compatible units, such as an annual rate with years.
Different results usually come from rate/time-unit mismatches, fees, or confusing simple interest with compound interest.
