Frequently asked questions
How much will $1,000,000 grow at 25% for 35 years?
$1,000,000 invested at 25% annual return compounded monthly for 35 years grows to $5768.1M. Your $1,000,000 earns $5767.1M in interest — a 5768.12× return. This assumes no withdrawals and full reinvestment of returns each month.
How long does it take $1,000,000 to double at 25%?
Using the Rule of 72, money doubles approximately every 3.1 years at 25% annual return. Starting with $1,000,000, you'd reach $2,000,000 in roughly 3.1 years. At 25% over 35 years, your money multiplies 5768.12× — doubling 12.5 times.
Is 25% a realistic annual return?
25% 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 25% to model optimistic best-case scenarios.
What is the difference between compound and simple interest on $1,000,000?
With simple interest at 25%, $1,000,000 earns $250,000 per year — $8.75M total over 35 years (final: $9.75M). With compound interest, the same principal grows to $5768.1M — $5758.4M more. The gap accelerates over time.
