Using the Rule of 72, money doubles approximately every 9.0 years at 8% annual return. Starting with $200,000, you'd reach $400,000 in roughly 9.0 years. At 8% over 35 years, your money multiplies 16.29× — doubling 4.0 times.
Is 8% a realistic annual return?
8% aligns with long-run equity market returns. The S&P 500 has historically averaged about 10% annually before inflation. A 8% 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.
