How $5,000 grows at 6%

Compound interest earns returns on your returns — not just your original investment. At 6% per year, your money doubles every 12 years (the Rule of 72). Over 25 years, that compounds to a 4.29× multiplier.

In year 1, $5,000 earns $300 in interest. By year 25, the annual interest has grown to $1,215 — because each year's interest is calculated on a larger balance.
