When Do You Stop Paying Interest on a Mortgage?

You stop paying interest on a mortgage the moment your principal balance reaches zero. Interest accrues daily on whatever principal is still outstanding, so the clock stops on the exact date the loan is paid in full, whether that happens through your last scheduled installment, an early payoff, the closing on a sale, or the funding of a refinance. Everything else about ending a mortgage, from payoff statements to lien releases, exists to pin down that date and prove it.

The Three Moments Interest Can Stop

A mortgage ends in one of a few ways, and each has its own cutoff.

If you ride out the amortization schedule, your final installment of a 15- or 30-year loan clears the small remaining principal plus interest for that last month. Once the payment posts, there is no balance left to charge against, and accrual ends automatically. You do not have to notify the lender or file anything to make interest stop.

If you pay the loan off early, interest stops the day the servicer receives and credits the full payoff amount. If you sell, it stops on the closing date, with the settlement agent calculating interest through that day as part of the payoff wired from sale proceeds. If you refinance, interest on the old loan stops the day the new loan funds and the old balance is retired.

In every case, the trigger is the same: zero principal. The rest of this article is about getting to that zero cleanly, on the day you intend.

Paying Off Early: Payoff Statements and Per Diem Interest

To pay a mortgage off ahead of schedule, you need a payoff statement from your servicer. It shows the exact dollar amount required to bring your balance to zero on a specific date. Federal law requires the servicer to provide this statement within seven business days of receiving your written request.¹ A loan in bankruptcy, foreclosure, or affected by a natural disaster gives the servicer more time, but it still has to respond within a reasonable period.

The payoff figure is your remaining principal plus accrued interest. Because mortgage interest is paid in arrears, meaning each month’s payment covers the prior month’s borrowing, the payoff includes interest for every day since your last payment posted. The statement also lists a per diem rate: the daily interest charge, calculated by dividing your annual interest by either 360 or 365 days depending on your loan terms. On a $300,000 balance at 6%, the per diem works out to roughly $49.32 per day using a 365-day year, or $50.00 using a 360-day year.

Payoff statements typically expire within 10 to 30 days because that per diem keeps running. If the statement expires before your funds reach the servicer, you will need a new one with updated figures. Review the statement for any administrative or processing fees before you send payment.

Getting the Final Payment There on Time

Every extra day between your statement’s “good through” date and the servicer’s receipt of funds adds another per diem charge. Most servicers require a wire transfer or certified bank check for a payoff because personal checks take days to clear. An outgoing domestic wire usually costs between $20 and $35 at major banks.

Federal law requires the servicer to credit the payment on the date it is received.¹ If funds arrive even a day after the statement’s quoted date, you will owe a small supplemental amount for the extra per diem. Once the servicer confirms a zero balance, interest stops that day.

Check for a Prepayment Penalty First

Before you send extra principal or a full payoff, confirm whether your loan carries a prepayment penalty. Federal law restricts these fees sharply. For a qualified mortgage, the category that covers most loans originated since 2014, prepayment penalties are allowed only in the first three years, capped at 2% of the outstanding balance during years one and two and 1% during year three.² After three years, no prepayment penalty is permitted on a qualified mortgage at all.

Non-qualified mortgages, including some jumbo loans, interest-only products, and loans with balloon payments, may also carry penalties, but federal law still prohibits them beyond three years from the closing date.² If you do pay a penalty, you can generally deduct it as mortgage interest on your federal return.³

When You Sell the Home

At a sale, interest stops accruing on the closing date. The settlement agent, usually a title company or attorney, calculates interest from your last monthly payment through the day of closing and includes that amount in the payoff wired to your lender from sale proceeds. You only owe interest for the days you actually owned the home during that final month.

The prorated interest appears on your settlement statement, and the payoff typically goes directly from the closing agent to your servicer. Once the servicer receives the full amount, the loan is satisfied and no further interest accrues. Any proceeds above the payoff balance and closing costs come to you.

When You Refinance

During a refinance, interest on the old loan keeps accruing until the new loan funds and the old balance is paid off. That funding date is the cutoff: the old rate stops and the new one starts. Your Closing Disclosure for the new loan itemizes the exact number of days of interest owed to the previous lender.⁴

Because mortgage interest is paid in arrears, you will also owe prepaid interest on the new loan covering the closing date through the end of that month.⁴ You briefly pay interest to both lenders: the old one for the final days of the old loan, and the new one for the opening days of the new loan. The new lender usually handles the payoff of the old loan directly to avoid a gap.

How Rescission Affects the Date Interest Stops

If you refinance your primary residence with a new lender, federal law gives you a three-day cooling-off period during which you can cancel without penalty.⁵ During those three business days the new loan typically cannot fund, so interest on the old loan keeps running until the rescission window closes and the new loan actually closes.

There is one exception. If you refinance with your current lender and take no cash out, the right of rescission does not apply, and the new loan can fund immediately.⁵ That can shave several days of per diem interest off the old loan.

Confirming the Loan Is Actually Closed

Interest stops when the balance hits zero, but a few loose ends still need to settle before the file is truly closed.

Satisfaction of Mortgage

After the servicer receives your full payoff, it is required to prepare a satisfaction of mortgage, also called a release of mortgage or reconveyance depending on your state. This document confirms that the lien on your property has been released. State deadlines for recording it with the county vary but generally fall between 30 and 60 days after payoff. The county clerk may charge a recording fee. Once recorded, the document is public notice that you own the property free and clear.

Escrow Refund

If your mortgage had an escrow account for property taxes and homeowner’s insurance, the servicer must return any remaining escrow balance to you within 20 business days after the loan is paid in full.⁶ Business days exclude weekends and federal holidays, so the calendar time may run longer.

The servicer must also send a short-year escrow statement within 60 days of receiving the payoff funds, showing the final accounting of deposits and disbursements.⁷ If a property tax or insurance bill was due around the time of payoff, confirm whether the servicer paid it. If not, you are responsible for paying those bills directly once the escrow account closes.

One exception: if you refinance with the same lender or its assignee, you can agree to transfer the remaining escrow balance to the new loan’s escrow account instead of taking a refund.⁶

Interest You Can Still Deduct the Year the Loan Ends

The year the loan ends is also the last year the mortgage interest deduction applies. You can deduct the interest paid during that calendar year up to the federal limit on eligible mortgage debt. For loans taken out after December 15, 2017, the deduction covers interest on up to $750,000 of mortgage debt, or $375,000 if married filing separately.⁸ Loans originated on or before that date remain eligible under the previous $1,000,000 limit.

If you sold the home, you can deduct interest paid up to, but not including, the date of sale. The prorated interest from the settlement statement counts toward the deduction for that year.³ Your servicer will report the total interest paid during the year on Form 1098; compare it against your payoff statement and any settlement sheet to be sure the final months of interest are captured.
