Why your mortgage payoff is higher than your statement balance

By Brendan Lawrence · Updated August 21, 2026

You're working out what you'd walk away with, you pull up your mortgage statement, and you type the balance into the box. For this purpose that number is wrong, and it's wrong in the direction that flatters you.

The balance on your statement is what you owed at a moment that has already passed. The payoff is what it takes to close the loan out on a specific future day. Interest keeps running in between, and a few other things can ride along. Whether the difference is a rounding error or real money depends on your balance, your rate, and how many days pass before the funds land. That's what the calculator below is for.

Use the "principal balance" or "unpaid principal balance" line. Not the "amount due", not the "total payment", and not the payoff figure if your statement happens to show one.

The note rate on the mortgage, not the APR. It's on your statement and on your Note. Second mortgage or HELOC? Run those separately and add them.

Mortgage interest is typically paid in arrears, so your last payment covered the month that just ended. Count from the due date of that payment (usually the first of the month), not from the date printed on your statement, through to the day the payoff money actually reaches your servicer. Then add a few days of cushion: wires don't always land the day they're sent, and closing dates move. If another monthly payment posts before closing, your balance drops and this figure will run high.

Optional. Taxes and insurance your servicer is holding. Leave it at 0 if you're not sure. It doesn't reduce the payoff below, and that's deliberate: federal rule generally requires the servicer to return whatever is left in escrow within 20 days (not counting weekends and legal public holidays) after the loan is paid in full, so for many sellers it arrives after closing, separately. If your payoff statement nets it against the amount due instead, use the statement's number.

Your estimated payoff

$313,948

Here is the arithmetic

The daily figure is rounded to the cent, and every line after it uses that rounded figure, so this reconciles if you check it by hand. The 365-day year is this calculator's assumption. Servicers differ, and some use a 360-day year, which makes the daily figure slightly larger. If your payoff statement names the per diem it used, that's the number that governs.

This is an estimate built from the numbers you entered. It doesn't include unpaid late fees, a prepayment penalty if your loan has one, an escrow shortage, or any recording or delivery charges your lender adds. Only your lender's official payoff statement, quoted good through a specific date, governs what actually pays off the loan.

Why the payoff is higher

Three things, in roughly the order they matter.

Interest that's accrued since your last payment. Mortgage interest is typically paid in arrears. The CFPB puts it this way: "Typically, mortgage interest is paid one month in arrears, meaning that, for example, if the first scheduled periodic payment due is on November 1st, it will cover interest accrued in the preceding month of October." So the payment you made on the first covered the month that just ended, not the month you're in now. From that payment's due date, interest started accumulating on the balance again, day by day, and none of it shows on your statement. This is usually the largest part of the gap.

Fees you haven't paid yet. The CFPB again: your payoff amount "includes the payment of any interest due through the day you intend to pay off your loan," and "may also include other fees you have been charged and have not yet paid." A late fee from eighteen months ago you'd forgotten about counts.

A prepayment penalty, if your loan has one. Not all mortgages have one, and the rules narrowed them considerably for loans written since 2014. Some sellers still have one. There's a section on how to tell below.

The arithmetic, so you can check it

Interest accrues daily on the outstanding principal. The daily figure is called the per diem:

principal balance × annual rate ÷ 365 = interest per day

Say your statement shows a principal balance of $312,480 at 6.125%, and 28 days of interest will run before the payoff funds reach your servicer. Those are example numbers, not data about anything:

Run yours in the calculator above.

Two caveats on how that arithmetic gets done in the real world. First, count your days from the date through which interest has already been paid, which for a standard monthly mortgage is the due date of your most recent payment. That's usually a few days before the date printed on your statement, and counting from the statement date understates what you owe. Second, the 365-day year is this page's assumption, not a universal rule. Servicers differ, and some use a 360-day year, which makes the daily figure slightly larger. If your payoff statement names the per diem it used, that's the number that governs, not this one.

Why the quote comes with an expiry date

A payoff is only correct for the day it's quoted for. Regulation Z requires a statement of what it takes to pay the loan in full "as of a specified date," so every payoff statement is tied to a date, usually printed as a "good through" date. Past it, the per diem has kept running and the figure is stale.

Two practical consequences. First, ask for the quote to run to your target closing date plus a cushion, because wires don't always land the day they're sent and closing dates move. Second, if closing slips past the good-through date, someone has to order a fresh statement. Work out who that someone is before it becomes urgent.

How far ahead a servicer will quote varies, so read the date printed on yours rather than assuming you have a month.

What a payoff statement is and how to get one

It's the lender's official, dated answer to "what does it take to close this loan out." You may also see it called a payoff demand or a demand statement.

For a consumer credit transaction secured by a dwelling, Regulation Z says a creditor, assignee or servicer "must provide an accurate statement of the total outstanding balance that would be required to pay the consumer's obligation in full as of a specified date," and that the statement "shall be sent within a reasonable time, but in no case more than seven business days, after receiving a written request from the consumer or any person acting on behalf of the consumer." The rule allows longer where a loan is in bankruptcy or foreclosure, where it's a reverse mortgage or shared appreciation mortgage, or because of natural disasters or similar circumstances.

Two things about that clock. It runs from a written request. And the official commentary lets the servicer "specify reasonable requirements for making payoff requests, such as requiring requests to be directed to a mailing address, email address, or fax number specified by" them. So find your servicer's payoff request instructions, on your statement or in your online account, and follow them exactly rather than emailing whoever you last spoke to.

One limit worth knowing. Regulation Z covers consumer credit. Credit extended primarily for a business or commercial purpose, which is how a lot of rental and investor loans are written, is exempt from Regulation Z, so this seven-day clock generally doesn't reach it. The same carve-out applies to the escrow rule below.

Often your title company or closing attorney orders the payoff for you. Whether that's how your closing works depends on your state and your closer, so ask. You can request one yourself as well, and there's no reason not to: seeing it before closing day is the only way to catch a line item you disagree with while there's still time to argue about it.

What happens to your escrow

If your servicer holds escrow for taxes and insurance, that balance doesn't vanish at closing.

Regulation X: "within 20 days (excluding legal public holidays, Saturdays, and Sundays) of a borrower's payment of a mortgage loan in full, a servicer shall return to the borrower any amounts remaining in an escrow account that is within the servicer's control." So for many sellers the escrow balance comes back separately, after closing, as its own refund. Two scope notes: Regulation X's definition of "mortgage loan" excludes open-end lines of credit, and RESPA exempts credit made primarily for a business purpose. And if you agree to it, the servicer may instead credit the balance to an escrow account on a new loan.

That's why the calculator above doesn't subtract escrow from your payoff. Subtracting it would understate what has to be wired at closing. Counting it twice, once as a reduction in payoff and again as a refund, would overstate what you end up with.

Three things to watch:

One knock-on for the net proceeds calculator on the homepage: it has no escrow field, so a refund arriving after closing isn't inside that number. Add it yourself when you're working out what actually lands in your account.

If the refund doesn't arrive, failure "to refund an escrow account balance" is one of the errors Regulation X's error-resolution procedure explicitly covers, so a written notice of error to your servicer is the route. Failure "to provide an accurate payoff balance amount" is on the same list.

Prepayment penalties: what the rules actually say

This is the part where a lot of what you'll read online is out of date.

The CFPB's Ability-to-Repay and Qualified Mortgage rule took effect on January 10, 2014. Under it, a covered transaction (broadly, a consumer credit transaction secured by a dwelling) "must not include a prepayment penalty unless" all of these hold: the penalty is otherwise permitted by law, the loan has an APR that cannot increase after consummation, the loan is a qualified mortgage under one of the specific paragraphs the rule lists, and the loan is not a higher-priced mortgage loan. On top of that, a penalty "must not apply after the three-year period following consummation," and must not exceed 2 percent of the balance prepaid during the first two years or 1 percent during the third year. The creditor also had to offer a comparable alternative loan without a penalty.

Read practically: if your mortgage dates from after January 2014 and you're more than three years into it, a prepayment penalty under that rule generally isn't in play. That's the common case, and it's why "watch out for prepayment penalties" is much weaker advice today than it was in 2007.

Four situations where it's still worth checking:

The CFPB's consumer guidance says a prepayment penalty typically applies only if you pay off the entire balance, "for example, because you sold your home or are refinancing your mortgage," within "a specific number of years (usually three or five years)." That five-year figure describes the category broadly, including loans the three-year cap above doesn't reach. It also says whether your loan carries one "must have been disclosed in your loan documents," and that "sometimes it is only disclosed in something called the 'Addendum to the Note.'" If you think you might have one, read your Note and anything with "Addendum" in the title, then ask your servicer to confirm in writing before you commit to a closing date.

The smaller line items on a payoff quote

After payoff, the lien on your house has to be released, and state property records are where you check whether that actually happened. The CFPB points you to your local Secretary of State or county recorder of deeds, notes that your lender should also return the original note to you, and warns there can be a delay between paying off the mortgage and the release. Who files what, and on what deadline, is state law and varies, so verify it yourself a few weeks after closing rather than assuming.

Recording itself is a government charge. The CFPB defines government recording charges as "fees assessed by state and local government agencies for legally recording your deed, mortgage and documents related to your home loan," and notes that "either a buyer or a seller may pay these fees." Whether a release or recording charge shows up on your payoff quote, on your closing statement, or on neither depends on your lender and your state. Some quotes also carry a wire, fax, or courier charge for delivering the funds or the statement.

If you see a fee you don't recognize, ask your servicer to point to where in your loan documents it's authorized. That's a reasonable question and asking it before closing costs you nothing.

If you have more than one lien

A second mortgage, a home equity loan, and a HELOC each have their own payoff, their own per diem, and their own good-through date. Run each one separately and add them. That total is what belongs in the homepage calculator's payoff field, which covers loans plus HELOC.

HELOCs need one extra step. A revolving line at a zero balance and a closed line aren't the same thing, and it's the closure and lien release that clears title. Ask your lender in writing what they require to close the line and release the lien, and confirm with your title company that they have what they need.

What to do with this

  1. Find the principal balance on your latest statement, not the "amount due" and not the "total payment." Regulation Z requires periodic statements for most closed-end mortgages to show "the amount of the outstanding principal balance," so it should be on there.
  2. Run the calculator above with your rate and a realistic day count, measured from the due date of your last payment, with a cushion on top.
  3. Request the official payoff statement in writing, quoted to your target closing date, following your servicer's stated request instructions. Ask your title company or closing attorney whether they're already ordering it.
  4. When it arrives, read three things: the good-through date, the per diem, and every line item you didn't expect.
  5. Put the payoff figure, not the statement balance, into the net proceeds calculator. While you're there, the cost guide covers the rest of the closing side, and the paperwork guide covers the documents around it.

None of this is legal advice and none of it is specific to your loan. Loan terms, state law, and servicer practice all vary, and neither the author nor this site is a lawyer, a licensed agent, or your servicer. Your servicer, your title company, and a local real estate attorney are the ones who can confirm your specifics.
