Frequently asked questions

How much will $200,000 grow at 7% for 30 years?

$200,000 invested at 7% annual return compounded monthly for 30 years grows to $1.62M. Your $200,000 earns $1.42M in interest — a 8.12× return. This assumes no withdrawals and full reinvestment of returns each month.

How long does it take $200,000 to double at 7%?

Using the Rule of 72, money doubles approximately every 10.2 years at 7% annual return. Starting with $200,000, you'd reach $400,000 in roughly 10.2 years. At 7% over 30 years, your money multiplies 8.12× — doubling 3.0 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 $200,000?

With simple interest at 7%, $200,000 earns $14,000 per year — $420,000 total over 30 years (final: $620,000). With compound interest, the same principal grows to $1.62M — $1.00M more. The gap accelerates over time.
