Frequently asked questions

How much will $1,000 grow at 15% for 2 years?

$1,000 invested at 15% annual return compounded monthly for 2 years grows to $1,347. Your $1,000 earns $347 in interest — a 1.35× return. This assumes no withdrawals and full reinvestment of returns each month.

How long does it take $1,000 to double at 15%?

Using the Rule of 72, money doubles approximately every 5.0 years at 15% annual return. Starting with $1,000, you'd reach $2,000 in roughly 5.0 years. At 15% over 2 years, your money multiplies 1.35× — doubling 0.4 times.

Is 15% a realistic annual return?

15% 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 15% to model optimistic best-case scenarios.

What is the difference between compound and simple interest on $1,000?

With simple interest at 15%, $1,000 earns $150 per year — $300 total over 2 years (final: $1,300). With compound interest, the same principal grows to $1,347 — $47 more. The gap accelerates over time.
