How long does it take $150,000 to double at 11%?
Using the Rule of 72, money doubles approximately every 6.6 years at 11% annual return. Starting with $150,000, you'd reach $300,000 in roughly 6.6 years. At 11% over 35 years, your money multiplies 46.18× — doubling 5.5 times.
Is 11% a realistic annual return?
11% 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 11% to model optimistic best-case scenarios.
