How long does it take $5,000 to double at 15%?
Using the Rule of 72, money doubles approximately every 5.0 years at 15% annual return. Starting with $5,000, you'd reach $10,000 in roughly 5.0 years. At 15% over 20 years, your money multiplies 19.72× — doubling 4.3 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.
