Frequently asked questions
- Does this assume end-of-month contributions?
- Yes, this uses the future value of an ordinary annuity (end-of-period payments). For beginning-of-month contributions, your actual result will be slightly higher.
- What return rate should I use?
- Historically, a diversified stock portfolio has returned about 7-10% annually before inflation. Use 5-7% for a more conservative, inflation-adjusted estimate.
