Use this calculator to see the magic of compound interest.

Play with the numbers, watch the magic!

Investing in the stock market is not magic, but compound interest is. Investing long-term in a Three-Fund Portfolio or a Target Date Fund that grows at 7-9% will make you rich over time.

Gambling, trying to pick that winning stock, will not. No one beats the market long-term.

See what effect changing the amounts and time will have on your future wealth.

Starting Balance - assuming you start with zero dollars in your investment account.
Annual Gain - The rate at which the account will grow. 7% is a conservative number. 10% is the S&P500 long-term average.
Time Period - how long the snowball has been rolling.

Albert Einstein (turns out he was an investor, just like you.):

“Compound interest is the eighth wonder of the world. He who understands it, earns it; he who doesn't, pays it.”
