Frequently asked questions
How much will $5,000 grow at 20% for 35 years?
$5,000 invested at 20% annual return compounded monthly for 35 years grows to $5.18M. Your $5,000 earns $5.17M in interest — a 1035.16× return. This assumes no withdrawals and full reinvestment of returns each month.
How long does it take $5,000 to double at 20%?
Using the Rule of 72, money doubles approximately every 3.8 years at 20% annual return. Starting with $5,000, you'd reach $10,000 in roughly 3.8 years. At 20% over 35 years, your money multiplies 1035.16× — doubling 10.0 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 $5,000?
With simple interest at 20%, $5,000 earns $1,000 per year — $35,000 total over 35 years (final: $40,000). With compound interest, the same principal grows to $5.18M — $5.14M more. The gap accelerates over time.
