How $2,000 grows at 10%
Compound interest earns returns on your returns — not just your original investment. At 10% per year, your money doubles every 7.2 years (the Rule of 72). Over 25 years, that compounds to a 10.83× multiplier.
In year 1, $2,000 earns $200 in interest. By year 25, the annual interest has grown to $1,970 — because each year's interest is calculated on a larger balance.
