How $50,000 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 5 years, that compounds to a 1.28× multiplier.

In year 1, $50,000 earns $2,500 in interest. By year 5, the annual interest has grown to $3,039 — because each year's interest is calculated on a larger balance.
