How do I calculate compound interest?

Compound interest is calculated using the formula: A = P(1 + r/n)^(nt), where A is the final amount, P is the principal (initial investment), r is the annual interest rate (as a decimal), n is the number of times interest is compounded per year, and t is the number of years. Our compound interest calculator handles this complex interest calculator automatically. For example, if you invest $10,000 at 6% annual interest, compounded monthly for 10 years: n=12, r=0.06, t=10, and the future value is $18,193.97.
