How $2,000 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 30 years, that compounds to a 4.32× multiplier.
In year 1, $2,000 earns $100 in interest. By year 30, the annual interest has grown to $412 — because each year's interest is calculated on a larger balance.
