How long does it take $1,000 to double at 10%?

Using the Rule of 72, money doubles approximately every 7.3 years at 10% annual return. Starting with $1,000, you'd reach $2,000 in roughly 7.3 years. At 10% over 5 years, your money multiplies 1.65× — doubling 0.7 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. A 10% 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.
