How $5,000 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 5 years, that compounds to a 1.40× multiplier.

In year 1, $5,000 earns $350 in interest. By year 5, the annual interest has grown to $459 — because each year's interest is calculated on a larger balance.

This is why longer holding periods matter so much. The later years do more of the heavy lifting, especially once the balance is large enough to generate bigger dollar returns each year.
