How $1,000 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 5 years, that compounds to a 1.34× multiplier.

In year 1, $1,000 earns $60 in interest. By year 5, the annual interest has grown to $76 — because each year's interest is calculated on a larger balance.
