Frequently asked questions
How much will $5,000 grow at 12% for 35 years?

How long does it take $5,000 to double at 12%?
Using the Rule of 72, money doubles approximately every 6.1 years at 12% annual return. Starting with $5,000, you'd reach $10,000 in roughly 6.1 years. At 12% over 35 years, your money multiplies 65.31× — doubling 6.0 times.
Is 12% a realistic annual return?
12% 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 12% to model optimistic best-case scenarios.
