Frequently asked questions

How much will $5,000 grow at 20% for 10 years?

$5,000 invested at 20% annual return compounded monthly for 10 years grows to $36,341. Your $5,000 earns $31,341 in interest — a 7.27× return. This assumes no withdrawals and full reinvestment of returns each month.

How long does it take $5,000 to double at 20%?

Using the Rule of 72, money doubles approximately every 3.8 years at 20% annual return. Starting with $5,000, you'd reach $10,000 in roughly 3.8 years. At 20% over 10 years, your money multiplies 7.27× — doubling 2.9 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 $5,000?

With simple interest at 20%, $5,000 earns $1,000 per year — $10,000 total over 10 years (final: $15,000). With compound interest, the same principal grows to $36,341 — $21,341 more. The gap accelerates over time.
