How the Mathematics Works

The future value of a series of equal periodic payments can be calculated with the formula:

FV = P [(1 + r)^n 1] / r

Where:

• FV = Future value of the investment
• P = Periodic payment amount
• r = Periodic interest rate (annual rate divided by number of periods per year)
• n = Total number of payments

Example: Investing $200 each month for 10 years at an annual return of 7% (0.583% per month) yields:

The power of compounding becomes more pronounced the longer the horizon, which is why early, regular investing is so effective.
