Frequently asked questions

How much will $500,000 grow at 11% for 10 years?

$500,000 invested at 11% annual return compounded monthly for 10 years grows to $1.49M. Your $500,000 earns $994,575 in interest — a 2.99× return. This assumes no withdrawals and full reinvestment of returns each month.

How long does it take $500,000 to double at 11%?

Using the Rule of 72, money doubles approximately every 6.6 years at 11% annual return. Starting with $500,000, you'd reach $1,000,000 in roughly 6.6 years. At 11% over 10 years, your money multiplies 2.99× — doubling 1.6 times.

Is 11% a realistic annual return?

11% is an aggressive assumption — above the S&P 500's ~10% historical average. Individual stocks, sector ETFs, or leveraged positions may achieve this, but it's not reliable for planning purposes. Financial planners typically use 6–8% for retirement projections. Use 11% to model optimistic best-case scenarios.
