Frequently asked questions

How much will $30,000 grow at 20% for 5 years?

How long does it take $30,000 to double at 20%?

Using the Rule of 72, money doubles approximately every 3.8 years at 20% annual return. Starting with $30,000, you'd reach $60,000 in roughly 3.8 years. At 20% over 5 years, your money multiplies 2.70× — doubling 1.4 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.
