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 10 years, that compounds to a 2.37× multiplier.

In year 1, $2,000 earns $180 in interest. By year 10, the annual interest has grown to $391 — because each year's interest is calculated on a larger balance.
