How Simple Interest Works
Simple interest is a quick, straightforward method of calculating interest charges on a monetary loan or investment deposit. Unlike compound interest, simple interest does not reinvest earned interest back into the principal balance.
The Core Formula
Interest (I) = P x R x T- P = Principal Amount ($ or ₹)
- R = Rate of Interest per year (%)
- T = Time period in years
