How long does it take $3,000 to double at 12%?

Using the Rule of 72, money doubles approximately every 6.1 years at 12% annual return. Starting with $3,000, you'd reach $6,000 in roughly 6.1 years. At 12% over 1 years, your money multiplies 1.13× — doubling 0.2 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.
