Frequently asked questions

How much will $3,000 grow at 20% for 25 years?

How long does it take $3,000 to double at 20%?

Using the Rule of 72, money doubles approximately every 3.8 years at 20% annual return. Starting with $3,000, you'd reach $6,000 in roughly 3.8 years. At 20% over 25 years, your money multiplies 142.42× — doubling 7.2 times.

Is 20% a realistic annual return?

20% 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 20% to model optimistic best-case scenarios.
