How $2,000 grows at 9%

Compound interest earns returns on your returns — not just your original investment. At 9% per year, your money doubles every 8 years (the Rule of 72). Over 25 years, that compounds to a 8.62× multiplier.

In year 1, $2,000 earns $180 in interest. By year 25, the annual interest has grown to $1,424 — because each year's interest is calculated on a larger balance.
