The Universal Interest Formula
Simple interest is calculated only on the principal amount of a loan or deposit. The formula is straightforward:
Simple Interest (SI) = (P × R × T) ÷ 100
- P (Principal): The initial amount of money borrowed or invested.
- R (Rate): The annual interest rate percentage.
- T (Time): The duration in years.
Note: Unlike compound interest, simple interest does not charge or yield interest on accumulated interest.
