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 35 years, your money multiplies 23.06× — doubling 4.5 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. A 9% assumption is reasonable for a diversified stock portfolio over a long horizon. Actual year-to-year returns are volatile — this models the long-run average. Does not account for fees, taxes, or inflation.
