Using the Rule of 72, money doubles approximately every 10.2 years at 7% annual return. Starting with $10,000, you'd reach $20,000 in roughly 10.2 years. At 7% over 35 years, your money multiplies 11.51× — doubling 3.5 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.

Does not account for fees, taxes, or inflation.
