Pay off the mortgage, or invest the cash flow?
Send the same monthly cash flow to extra principal, or to an investment account. After the mortgage is gone, that path invests the retired payment plus the cash flow. No distributions are taken while the accounts grow. At the desired retirement year, the calculator applies the 4% rule to the balance at that point.
