Compound Interest Explained
Compound interest is the interest on your interest. The formula used is: FV = P(1+r)ⁿ + PMT × [((1+r)ⁿ − 1) / r], where FV is the future value, P is the principal, r is the periodic interest rate, n is the total number of compounding periods, and PMT is the periodic contribution. This is a projection only — actual returns vary and past performance does not guarantee future results.
