Frequently asked questions

How much will $500 grow at 20% for 5 years?

$500 invested at 20% annual return compounded monthly for 5 years grows to $1,348. Your $500 earns $848 in interest — a 2.70× return. This assumes no withdrawals and full reinvestment of returns each month.

How long does it take $500 to double at 20%?

Using the Rule of 72, money doubles approximately every 3.8 years at 20% annual return. Starting with $500, you'd reach $1,000 in roughly 3.8 years. At 20% over 5 years, your money multiplies 2.70× — doubling 1.4 times.

Is 20% a realistic annual return?

20% 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 20% to model optimistic best-case scenarios.

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

With simple interest at 20%, $500 earns $100 per year — $500 total over 5 years (final: $1,000). With compound interest, the same principal grows to $1,348 — $348 more. The gap accelerates over time.
