Frequently asked questions

How much will $40,000 grow at 25% for 5 years?

How long does it take $40,000 to double at 25%?

Using the Rule of 72, money doubles approximately every 3.1 years at 25% annual return. Starting with $40,000, you'd reach $80,000 in roughly 3.1 years. At 25% over 5 years, your money multiplies 3.45× — doubling 1.8 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.
