How long does it take $500 to double at 25%?

Using the Rule of 72, money doubles approximately every 3.1 years at 25% annual return. Starting with $500, you'd reach $1,000 in roughly 3.1 years. At 25% over 7 years, your money multiplies 5.65× — doubling 2.5 times.

Is 25% a realistic annual return?

25% 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.
