Frequently asked questions

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 35 years, your money multiplies 5768.12× — doubling 12.5 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.
