Frequently asked questions
What is the compound interest formula?
A = P(1 + r/n)^(nt), where P is principal, r the annual rate, n the compoundings per year, and t the years.
How does compounding frequency affect returns?
More frequent compounding (e.g. monthly vs annual) earns slightly more, because interest is added and itself earns interest sooner.
