Simple vs Compound Interest

Simple Interest

Interest is calculated only on the principal amount. It remains constant over time.

Formula: SI = (P × R × T) / 100

Compound Interest

Interest is calculated on the principal + previously accumulated interest. It grows faster ("interest on interest").

Formula: A = P(1 + r/n)^(nt)
