Frequently asked questions

How long does it take $50,000 to double at 12%?
Using the Rule of 72, money doubles approximately every 6.1 years at 12% annual return. Starting with $50,000, you'd reach $100,000 in roughly 6.1 years. At 12% over 20 years, your money multiplies 10.89× — doubling 3.4 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.
