Frequently asked questions

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

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

Using the Rule of 72, money doubles approximately every 6.6 years at 11% annual return. Starting with $500, you'd reach $1,000 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.
