Explanation

Simple interest is calculated on original principal only: I = PRT, where P = principal, R = rate (as decimal), T = time (in years). Total amount = P + I.

Example: ₦10,000 at 5% for 3 years. I = 10,000 × 0.05 × 3 = ₦1,500. Total = ₦11,500. Interest stays constant each year (₦500 annually).

Differs from compound interest where interest earns interest. Simple interest is less realistic for long-term investments but simpler to calculate. Used in some short-term loans.
