Frequently asked questions

How much will $500 grow at 12% for 5 years?

$500 invested at 12% annual return compounded monthly for 5 years grows to $908. Your $500 earns $408 in interest — a 1.82× return. This assumes no withdrawals and full reinvestment of returns each month.

How long does it take $500 to double at 12%?

Using the Rule of 72, money doubles approximately every 6.1 years at 12% annual return. Starting with $500, you'd reach $1,000 in roughly 6.1 years. At 12% over 5 years, your money multiplies 1.82× — doubling 0.9 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.

What is the difference between compound and simple interest on $500?

With simple interest at 12%, $500 earns $60 per year — $300 total over 5 years (final: $800). With compound interest, the same principal grows to $908 — $108 more. The gap accelerates over time.
