Q: What payment should I enter?

Enter the principal-and-interest portion of your monthly mortgage payment. Do not include taxes, insurance, or escrow.

See how extra monthly payments, one extra principal payment each year, or a one-time principal payment can shorten your mortgage and reduce interest. The calculator starts with your current balance, so you do not need the original loan amount or term.

How it works

Plan extra mortgage payments from today's balance

The calculator compares your current payment path with a plan that includes the extra monthly amount and optional one-time principal payment you enter.

Interest is estimated monthly using a fixed rate. The result shows an estimated payoff month rather than an exact payoff day.

What to enter for monthly payment

Use only the principal-and-interest portion of the mortgage payment. If your bank withdraws one amount that includes property taxes, homeowners insurance, or escrow, remove those items before entering the payment here.

Frequently asked questions

What payment should I enter?

Enter only the principal-and-interest portion of your monthly mortgage payment. Do not include taxes, insurance, or escrow.

Is this an exact mortgage payoff quote?

No. It is a month-based planning estimate. Your mortgage servicer can provide an official payoff amount for a specific date.

Can I include monthly, annual, and one-time extra payments?

Yes. Enter a recurring monthly extra amount, an extra principal payment once per year, and/or a one-time extra principal payment.

Why does the calculator show a payoff month instead of a day?

The calculator is intentionally month-based to keep consumer payoff planning simple and avoid implying servicer-specific daily-interest precision.
