Compound interest formula

A = P × (1 + r/n)^(n×t), where P is the principal, r the annual rate, n the number of times interest compounds per year and t the time in years. Compound interest = A − P. Because interest is added back to the principal, your money grows faster than with simple interest — and more frequent compounding means slightly more.

FAQs

What is the compound interest formula?

A = P × (1 + r/n)^(n×t). Compound interest is A − P, where n is how many times it compounds per year.

Does compounding frequency matter?

Yes — more frequent compounding (monthly vs yearly) gives slightly higher returns at the same rate.
