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)
