How this calculator works
Compound interest uses A = P(1 + r/n)^(nt), where P is your principal, r is the annual rate, n is how many times per year interest compounds, and t is the number of years. Unlike simple interest, each compounding period earns interest on the interest already accumulated, not just the original principal.
More frequent compounding (daily or monthly versus yearly) produces a slightly higher return for the same stated rate, since interest starts earning its own interest sooner — try switching the frequency above to see the effect for yourself.
