Frequently asked questions

How much will $50,000 grow at 25% for 30 years?

$50,000 invested at 25% annual return compounded monthly for 30 years grows to $83.7M. Your $50,000 earns $83.6M in interest — a 1673.95× return. This assumes no withdrawals and full reinvestment of returns each month.

How long does it take $50,000 to double at 25%?

Using the Rule of 72, money doubles approximately every 3.1 years at 25% annual return. Starting with $50,000, you'd reach $100,000 in roughly 3.1 years. At 25% over 30 years, your money multiplies 1673.95× — doubling 10.7 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%, $50,000 earns $12,500 per year — $375,000 total over 30 years (final: $425,000). With compound interest, the same principal grows to $83.7M — $83.3M more. The gap accelerates over time.
