Frequently asked questions

How much will $15,000 grow at 20% for 5 years?

$15,000 invested at 20% annual return compounded monthly for 5 years grows to $40,440. Your $15,000 earns $25,440 in interest — a 2.70× return. This assumes no withdrawals and full reinvestment of returns each month.

How long does it take $15,000 to double at 20%?

Using the Rule of 72, money doubles approximately every 3.8 years at 20% annual return. Starting with $15,000, you'd reach $30,000 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 $15,000?

With simple interest at 20%, $15,000 earns $3,000 per year — $15,000 total over 5 years (final: $30,000). With compound interest, the same principal grows to $40,440 — $10,440 more. The gap accelerates over time.
