How compound interest works

Compound interest earns returns on both your original principal and previously accumulated interest. The formula is A = P(1 + r/n)^(nt), where P is principal, r is the annual rate, n is compounding frequency, and t is time in years.

More frequent compounding (e.g. daily vs. annually) produces slightly higher returns because interest is reinvested sooner.
