What happens when you invest $1000/month at 12% for 30 years?

If you invest $1000 per month consistently at an expected annual return of 12% for 30 years, your portfolio grows to $3,494,964. You will have contributed $360,000 of your own money, and compounding will have added $3,134,964 in growth — a 9.71x multiple on your contributions.

After a typical 0.5% annual management fee, the final value is approximately $3,129,097. The total fee cost over 30 years is $365,867 — 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 12% annual return compounded monthly. Actual investment returns vary year-to-year and cannot be guaranteed. Use the interactive calculator to model different assumptions.
