How long does it take $200,000 to double at 9%?

Using the Rule of 72, money doubles approximately every 8.0 years at 9% annual return. Starting with $200,000, you'd reach $400,000 in roughly 8.0 years. At 9% over 10 years, your money multiplies 2.45× — doubling 1.3 times.

Is 9% a realistic annual return?

9% aligns with long-run equity market returns. The S&P 500 has historically averaged about 10% annually before inflation.
