What happens when you invest $1000/month at 10% for 30 years?
If you invest $1000 per month consistently at an expected annual return of 10% for 30 years, your portfolio grows to $2,260,488. You will have contributed $360,000 of your own money, and compounding will have added $1,900,488 in growth — a 6.28x multiple on your contributions.
After a typical 0.5% annual management fee, the final value is approximately $2,033,035. The total fee cost over 30 years is $227,453 — a reminder that low-cost index funds with fees of 0.03-0.1% preserve significantly more of your returns.
These figures assume a constant 10% annual return compounded monthly. Actual investment returns vary year-to-year and cannot be guaranteed. Use the interactive calculator to model different assumptions.
