Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal sum plus previously accumulated interest.

Compound Interest Formula: A = P(1 + r/n)^(nt) + PMT×[((1 + r/n)^(nt) - 1)/(r/n)]
Where: A = Final amount, P = Principal, r = Annual interest rate, n = Compound frequency, t = Time in years, PMT = Monthly contribution
