What is the Simple Interest Calculator?
Simple interest is interest calculated only on the original principal, never on accumulated interest. It's used for some short-term loans and instruments.
How to Calculate
SI = P × R × T ÷ 100, and the total amount is principal plus interest.
Formula
Simple Interest = (P × R × T) ÷ 100

Frequently Asked Questions
How is simple interest different from compound?
Simple interest is charged only on the principal, so it grows linearly. Compound interest earns interest on interest, growing faster over time.
