How long does it take $3,000 to double at 15%?

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.
