Frequently asked questions

How much will $200,000 grow at 12% for 20 years?

$200,000 invested at 12% annual return compounded monthly for 20 years grows to $2.18M. Your $200,000 earns $1.98M in interest — a 10.89× return. This assumes no withdrawals and full reinvestment of returns each month.

How long does it take $200,000 to double at 12%?

Using the Rule of 72, money doubles approximately every 6.1 years at 12% annual return. Starting with $200,000, you'd reach $400,000 in roughly 6.1 years. At 12% over 20 years, your money multiplies 10.89× — doubling 3.4 times.

Is 12% a realistic annual return?

12% 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 12% to model optimistic best-case scenarios.

What is the difference between compound and simple interest on $200,000?

With simple interest at 12%, $200,000 earns $24,000 per year — $480,000 total over 20 years (final: $680,000). With compound interest, the same principal grows to $2.18M — $1.50M more. The gap accelerates over time.
