Understanding the Power of Compound Returns

Compound growth occurs when the earnings generated on your principal balance are reinvested to generate their own earnings. Over 10, 20, or 30 years, compounding often generates more wealth than the total cash deposited.

The Compound Interest Formula

FV = P(1 + r/n)^(nt) + PMT × [((1 + r/n)^(nt) − 1) / (r/n)]

Where FV is future value, P is starting principal, r is annual nominal interest rate, n is compounding frequency per year, t is number of years, and PMT is regular monthly contribution.
