How $5,000 grows at 5%

Compound interest earns returns on your returns — not just your original investment. At 5% per year, your money doubles every 14.4 years (the Rule of 72). Over 25 years, that compounds to a 3.39× multiplier.

In year 1, $5,000 earns $250 in interest. By year 25, the annual interest has grown to $806 — because each year's interest is calculated on a larger balance.
