What happens when you invest $500/month at 10% for 30 years?
If you invest $500 per month consistently at an expected annual return of 10% for 30 years, your portfolio grows to $1,130,244. You will have contributed $180,000 of your own money, and compounding will have added $950,244 in growth — a 6.28x multiple on your contributions.
After a typical 0.5% annual management fee, the final value is approximately $1,016,518. The total fee cost over 30 years is $113,726 — 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.
