Frequently asked questions

How much will $10,000 grow at 9% for 10 years?

$10,000 invested at 9% annual return compounded monthly for 10 years grows to $24,514. Your $10,000 earns $14,514 in interest — a 2.45× return. This assumes no withdrawals and full reinvestment of returns each month.

How long does it take $10,000 to double at 9%?

Using the Rule of 72, money doubles approximately every 8.0 years at 9% annual return. Starting with $10,000, you'd reach $20,000 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. 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.
