Using the Rule of 72, money doubles approximately every 7.3 years at 10% annual return. Starting with $200,000, you'd reach $400,000 in roughly 7.3 years. At 10% over 20 years, your money multiplies 7.33× — doubling 2.9 times.

Is 10% a realistic annual return?

10% aligns with long-run equity market returns. The S&P 500 has historically averaged about 10% annually before inflation.
