How $2,000 grows at 8%
Compound interest earns returns on your returns — not just your original investment. At 8% per year, your money doubles every 9 years (the Rule of 72). Over 25 years, that compounds to a 6.85× multiplier.
In year 1, $2,000 earns $160 in interest. By year 25, the annual interest has grown to $1,015 — because each year's interest is calculated on a larger balance.
