Frequently asked questions
How much will $1,000,000 grow at 11% for 30 years?
$1,000,000 invested at 11% annual return compounded monthly for 30 years grows to $26.7M. Your $1,000,000 earns $25.7M in interest — a 26.71× return. This assumes no withdrawals and full reinvestment of returns each month.
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 30 years, your money multiplies 26.71× — doubling 4.7 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.
What is the difference between compound and simple interest on $1,000,000?
With simple interest at 11%, $1,000,000 earns $110,000 per year — $3.30M total over 30 years (final: $4.30M). With compound interest, the same principal grows to $26.7M — $22.4M more. The gap accelerates over time.
