Frequently asked questions

How much will $1,000,000 grow at 12% for 7 years?

$1,000,000 invested at 12% annual return compounded monthly for 7 years grows to $2.31M. Your $1,000,000 earns $1.31M in interest — a 2.31× return. This assumes no withdrawals and full reinvestment of returns each month.

How long does it take $1,000,000 to double at 12%?

Using the Rule of 72, money doubles approximately every 6.1 years at 12% annual return. Starting with $1,000,000, you'd reach $2,000,000 in roughly 6.1 years. At 12% over 7 years, your money multiplies 2.31× — doubling 1.2 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.
