Frequently asked questions

How much will $1,000 grow at 25% for 10 years?

$1,000 invested at 25% annual return compounded monthly for 10 years grows to $11,874. Your $1,000 earns $10,874 in interest — a 11.87× return. This assumes no withdrawals and full reinvestment of returns each month.

How long does it take $1,000 to double at 25%?

Using the Rule of 72, money doubles approximately every 3.1 years at 25% annual return. Starting with $1,000, you'd reach $2,000 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.

With simple interest at 25%, $1,000 earns $250 per year — $2,500 total over 10 years (final: $3,500). With compound interest, the same principal grows to $11,874 — $8,374 more. The gap accelerates over time.
