How compound interest is calculated

Compound interest pays interest on both your original deposit and the interest already earned. The more frequently interest compounds, the faster the balance grows.

A = P × (1 + r/n)^(n × t)

Where P is the principal, r is the annual rate as a decimal (rate ÷ 100), n is the number of compounding periods per year and t is the time in years. Interest earned is A − P.
