The payment changes the calendar.

The estimate applies the APR monthly, then subtracts the fixed monthly payment until the balance reaches zero. The optional extra payment is added to that monthly amount.

Before you use the number.

What payment is used?

The calculator adds the monthly payment and the optional extra amount, then uses that combined amount for the payoff scenario.

What if the payment does not cover interest?

The calculator flags the scenario as not reaching payoff because the payment is not reducing the balance under the selected APR.
