Frequently asked questions

How much will $100,000 grow at 20% for 5 years?

$100,000 invested at 20% annual return compounded monthly for 5 years grows to $269,597. Your $100,000 earns $169,597 in interest — a 2.70× return. This assumes no withdrawals and full reinvestment of returns each month.

How long does it take $100,000 to double at 20%?

Using the Rule of 72, money doubles approximately every 3.8 years at 20% annual return. Starting with $100,000, you'd reach $200,000 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.

With simple interest at 20%, $100,000 earns $20,000 per year — $100,000 total over 5 years (final: $200,000). With compound interest, the same principal grows to $269,597 — $69,597 more. The gap accelerates over time.
