Simple interest is interest calculated only on the original principal amount, not on accumulated interest. Formula: SI = P × r × t / 100, where P = principal, r = annual rate (%), t = time in years.
SI = (P × R × T) / 100. Total Amount = P + SI. Where: P = principal amount, R = annual interest rate in percent, T = time period in years.
Simple interest is calculated only on the principal and stays the same every year. Compound interest is calculated on principal plus previously earned interest, so it grows faster over time.
