Closing math: what happens if the date moves
The payoff total is principal plus interest up to the day funds arrive. In this example:
- Per diem: $248,316.42 × 0.0625 ÷ 365 = $42.52 per day
- Interest: 24 days × $42.52 = $1,020.48
- Payoff: $248,316.42 + $1,020.48 + $35.00 − $150.00 = $249,221.90
If closing slips 3 days to November 27, 2026, the funds arrive after the good-through date. The servicer is owed 3 × $42.52 = $127.56 more, for a payoff of about $249,349.46. A seller’s net proceeds go down by the same amount. Ask the servicer for an updated statement rather than adding the per diem to the old one yourself.

Closing adjustments math practice on RealEstateExamHQ uses the same per-day method for property tax prorations and also covers seller credits and cash to close.
What happens to the escrow balance
The escrow balance usually isn’t subtracted from the payoff. Under federal Regulation X, when you pay a mortgage in full, the servicer must refund the remaining escrow balance within 20 days, not counting weekends and legal public holidays. One exception: if you agree, a servicer can credit the balance to a new escrow account when you refinance with the same lender or servicer. Make sure the servicer has your new mailing address before you move. (12 CFR 1024.34(b))
Get your own statement
Find your servicer’s payoff phone number, portal and fax in the mortgage company directory. For example, see the Rocket Mortgage (including former Mr. Cooper loans), Pennymac and BSI Financial guides. If you need to request it in writing or authorize a title company, use the payoff request letter template.
This example is for illustration. Your servicer’s statement is the only figure to pay from.
