Frequently asked questions

How much will $200,000 grow at 15% for 10 years?

How long does it take $200,000 to double at 15%?

Using the Rule of 72, money doubles approximately every 5.0 years at 15% annual return. Starting with $200,000, you'd reach $400,000 in roughly 5.0 years. At 15% over 10 years, your money multiplies 4.44× — doubling 2.2 times.

Is 15% a realistic annual return?

15% 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 15% to model optimistic best-case scenarios.
