How long does it take $1,000,000 to double at 11%?

Using the Rule of 72, money doubles approximately every 6.6 years at 11% annual return. Starting with $1,000,000, you'd reach $2,000,000 in roughly 6.6 years. At 11% over 3 years, your money multiplies 1.39× — doubling 0.5 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.
