Frequently asked questions
What is the compound interest formula?
A = P(1 + r/n)^(nt), where P is principal, r is the annual rate (decimal), n is compounding periods per year, and t is years. Interest = A − P.
Does more frequent compounding earn more?
Yes — monthly compounding earns slightly more than annual at the same rate, because interest starts earning interest sooner.
