Frequently asked questions

How much will $500,000 grow at 25% for 10 years?

$500,000 invested at 25% annual return compounded monthly for 10 years grows to $5.94M. Your $500,000 earns $5.44M in interest — a 11.87× return. This assumes no withdrawals and full reinvestment of returns each month.

How long does it take $500,000 to double at 25%?

Using the Rule of 72, money doubles approximately every 3.1 years at 25% annual return. Starting with $500,000, you'd reach $1,000,000 in roughly 3.1 years. At 25% over 10 years, your money multiplies 11.87× — doubling 3.6 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 $500,000?

With simple interest at 25%, $500,000 earns $125,000 per year — $1.25M total over 10 years (final: $1.75M). With compound interest, the same principal grows to $5.94M — $4.19M more. The gap accelerates over time.
