Frequently asked questions
How much will $100,000 grow at 11% for 25 years?
$100,000 invested at 11% annual return compounded monthly for 25 years grows to $1.54M. Your $100,000 earns $1.44M in interest — a 15.45× return. This assumes no withdrawals and full reinvestment of returns each month.
How long does it take $100,000 to double at 11%?
Using the Rule of 72, money doubles approximately every 6.6 years at 11% annual return. Starting with $100,000, you'd reach $200,000 in roughly 6.6 years. At 11% over 25 years, your money multiplies 15.45× — doubling 3.9 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 $100,000?
With simple interest at 11%, $100,000 earns $11,000 per year — $275,000 total over 25 years (final: $375,000). With compound interest, the same principal grows to $1.54M — $1.17M more. The gap accelerates over time.
