The Power of Compound Interest
Compound Interest is the addition of interest to the principal sum of a loan or deposit. It is essentially “interest on 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.
Formula: A = P(1 + r/n)^(nt)
Where A is the future value, P is principal, r is annual interest rate (decimal), n is compounding frequency, and t is time in years.
Albert Einstein reportedly called compound interest the “eighth wonder of the world.” Those who understand it, earn it; those who don’t, pay it.
