Frequently asked questions

How long does it take $100,000 to double at 7%?

Using the Rule of 72, money doubles approximately every 10.2 years at 7% annual return. Starting with $100,000, you'd reach $200,000 in roughly 10.2 years. At 7% over 10 years, your money multiplies 2.01× — doubling 1.0 times.

Is 7% a realistic annual return?

7% aligns with long-run equity market returns. The S&P 500 has historically averaged about 10% annually before inflation. A 7% 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.
