Frequently asked questions
How much will $5,000 grow at 20% for 20 years?

How long does it take $5,000 to double at 20%?
Using the Rule of 72, money doubles approximately every 3.8 years at 20% annual return. Starting with $5,000, you'd reach $10,000 in roughly 3.8 years. At 20% over 20 years, your money multiplies 52.83× — doubling 5.7 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.
