Frequently asked questions

How much will $1,000,000 grow at 7% for 10 years?

$1,000,000 invested at 7% annual return compounded monthly for 10 years grows to $2.01M. Your $1,000,000 earns $1.01M in interest — a 2.01× return. This assumes no withdrawals and full reinvestment of returns each month.

How long does it take $1,000,000 to double at 7%?

Using the Rule of 72, money doubles approximately every 10.2 years at 7% annual return. Starting with $1,000,000, you'd reach $2,000,000 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.

What is the difference between compound and simple interest on $1,000,000?

With simple interest at 7%, $1,000,000 earns $70,000 per year — $700,000 total over 10 years (final: $1.70M). With compound interest, the same principal grows to $2.01M — $309,661 more. The gap accelerates over time.
