Understanding Interest

Simple Interest

Simple interest is calculated only on the principal amount. It's the most basic type of interest calculation. Formula: I = P × R × T ÷ 100

Compound Interest

Compound interest is calculated on both the principal and accumulated interest. It grows exponentially based on how often it's compounded (annually, monthly, or daily).
