How $50,000 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, $50,000 earns $3,000 in interest. By year 5, the annual interest has grown to $3,787 — because each year's interest is calculated on a larger balance.
