Frequently asked questions

How much will $1,000,000 grow at 20% for 5 years?

$1,000,000 invested at 20% annual return compounded monthly for 5 years grows to $2.70M. Your $1,000,000 earns $1.70M in interest — a 2.70× return. This assumes no withdrawals and full reinvestment of returns each month.

How long does it take $1,000,000 to double at 20%?

Using the Rule of 72, money doubles approximately every 3.8 years at 20% annual return. Starting with $1,000,000, you'd reach $2,000,000 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 $1,000,000?

With simple interest at 20%, $1,000,000 earns $200,000 per year — $1.00M total over 5 years (final: $2.00M). With compound interest, the same principal grows to $2.70M — $695,970 more. The gap accelerates over time.
