Frequently asked questions

How much will $1,000,000 grow at 7% for 35 years?

$1,000,000 invested at 7% annual return compounded monthly for 35 years grows to $11.5M. Your $1,000,000 earns $10.5M in interest — a 11.51× 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 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. 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 — $2.45M total over 35 years (final: $3.45M). With compound interest, the same principal grows to $11.5M — $8.06M more. The gap accelerates over time.
