How $1,000 grows at 7%

Compound interest earns returns on your returns — not just your original investment. At 7% per year, your money doubles every 10.3 years (the Rule of 72). Over 10 years, that compounds to a 1.97× multiplier.

In year 1, $1,000 earns $70 in interest. By year 10, the annual interest has grown to $129 — because each year's interest is calculated on a larger balance.
