When Do You Stop Paying Interest on a Mortgage?

You stop paying interest on a mortgage the day your principal balance reaches zero. That can happen four ways: your final scheduled payment posts, you pay the loan off early, you sell the home, or you refinance and the new loan funds. Interest accrues daily on whatever principal is still outstanding, so the cutoff is a date, not a billing cycle. Federal rules govern how that final balance is calculated, when the lender must credit your payment, and what you can still deduct in the year the loan ends.

Reaching Zero on the Original Schedule

If you follow the amortization schedule all the way through, interest stops when the last installment of your 15- or 30-year term posts. Each monthly payment splits between interest and principal, and by the final year almost all of it goes to principal. The last payment covers the small remaining principal plus interest for that final month. Once it applies to your account, there is no principal left to charge interest on, and accrual stops automatically. Nothing else is required from you.

Paying Off Early

Because interest is calculated on the outstanding principal each day, paying the loan down ahead of schedule cuts off interest sooner. To do it cleanly, you need a payoff statement from your servicer showing the exact dollar amount required to bring the balance to zero on a specific date.

The Payoff Statement and Per Diem

Federal law requires your servicer to provide a payoff statement within seven business days of receiving your written request.¹ Loans in bankruptcy, foreclosure, or affected by a natural disaster get additional time but still must be answered within a reasonable period.

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

Payoff statements typically expire within 10 to 30 days because that per diem keeps accruing. Miss the expiration and you will need a fresh statement with updated figures. Administrative preparation fees sometimes appear on the statement, so read every line.

Check for a Prepayment Penalty First

Some lenders charge a fee for paying off ahead of schedule. Federal law sharply limits when they can. For a “qualified mortgage” — the category covering most loans originated since 2014 — prepayment penalties are allowed only during the first three years, capped at 2% of the outstanding balance in the first two years and 1% in the third year.² After three years, no prepayment penalty is allowed on a qualified mortgage.

Non-qualified mortgages, including some jumbo loans, interest-only products, and loans with balloon payments, may carry a penalty, but federal law still prohibits any prepayment penalty more than three years after closing.² If you do owe a penalty and pay it, you can generally deduct that amount as mortgage interest on your federal return.³

Getting the Payment Credited

Every extra day between the payoff statement date and the servicer’s receipt adds another per diem charge, so timing matters. Most servicers require a wire transfer or certified bank check for the final payoff. Personal checks are usually not accepted because they take days to clear. An outgoing domestic wire generally costs $20 to $35 at major banks.

Federal law requires the servicer to credit your payment on the date it is received.¹ If your funds arrive after the date on the payoff statement, expect a small supplemental interest bill. Once the servicer confirms a zero balance, interest stops accruing.

If the Payoff Amount Looks Wrong

If the statement contains an error — an interest miscalculation, an unexpected fee — you can file a written notice of error with your servicer, including your name, loan account information, and a description of the specific problem. For errors involving payoff balance accuracy, the servicer must respond within seven business days (excluding weekends and federal holidays), either correcting it or explaining its findings in writing.⁴ You have up to one year after the loan is discharged to file, so keep your payoff records after closing.

Selling the Home

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

Refinancing

When you refinance, interest on the old loan continues to accrue until the day the new loan funds and pays off the old balance. The funding date is the cutoff. Your Closing Disclosure for the new loan itemizes the exact number of days of interest owed to your previous lender. You will also owe prepaid interest on the new loan covering closing day through the end of that month, so you briefly pay both lenders for adjacent stretches of the same billing period.⁵

How the Right of Rescission Affects Timing

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.⁶ The new loan typically cannot fund during those three business days, so the old loan keeps accruing interest until the period expires and closing completes.

One exception: refinancing with your current lender with no cash out does not trigger the right of rescission, and the new loan can fund immediately.⁶ That can save several days of per diem interest on the old loan.

After Interest Stops: Lien Release and Escrow Refund

Once the servicer confirms a zero balance, it must prepare a satisfaction of mortgage (also called a release of mortgage or reconveyance, depending on your state) confirming the lien on your property is gone. The recording deadline varies by state but generally falls between 30 and 60 days after payoff. The county clerk may charge a recording fee. Recording that document gives public notice that the property is yours free of the lien.

If your mortgage included an escrow account for property taxes and homeowner’s insurance, the servicer must return any remaining escrow balance to you within 20 business days of full payoff.⁷ Because business days exclude weekends and federal holidays, actual calendar time can run longer. Within 60 days of receiving the payoff, the servicer must also send a short-year escrow statement showing the final accounting of deposits and disbursements.⁸

If a tax or insurance bill was due around the time of payoff, confirm with the servicer whether it was paid from escrow. If not, you owe it directly. One exception to the refund rule: refinancing with the same lender or its assignee lets you agree to transfer the remaining escrow balance to the new loan’s escrow account instead of taking the refund.⁷

Deducting Interest in the Year the Loan Ends

The year interest stops is your last chance to claim the mortgage interest deduction on that loan. You can deduct interest paid through the payoff date, up to the limit on eligible mortgage debt. For loans taken out after December 15, 2017, the deduction applies to interest on up to $750,000 of mortgage debt ($375,000 if married filing separately).⁹ Loans originated on or before that date remain under the previous $1,000,000 limit. If you sold the home, the prorated interest on your settlement statement counts toward the deduction for that year.³

Your servicer reports the total interest paid during the calendar year on Form 1098, which you should receive by early the following year.¹⁰ If the loan closed midyear, the form reflects only interest paid through the payoff date. Any prepaid interest on a closing or settlement statement should appear as well. Cross-check the 1098 against your payoff statement and any settlement sheets so nothing deductible gets left off your return.
