To calculate a loan payoff amount, add your current principal balance, the interest that will accrue each day until the lender receives your money, and any outstanding fees or prepayment charges. That total is almost always higher than the balance on your latest statement, because statements show what you owed on a past date and interest keeps building every day until the debt is settled.
What Goes Into the Total
Four things can appear in a payoff figure. Miss any one of them and the lender will treat your payment as a shortfall.
- Outstanding principal. The portion of the original loan you haven’t repaid. This is the largest piece and the starting point for the rest of the math.
- Accrued interest. Interest that has built up since your last payment posted. Most consumer loans, including mortgages and auto loans, use simple daily interest, meaning each day’s charge is based on the current principal rather than on previously accrued interest.1Consumer Financial Protection Bureau.

- Fees. Lenders may add administrative charges for processing the payoff or recording a lien release. Recording fees vary by county, often around $10 to $60.
- Prepayment penalties. Some agreements charge a fee for paying early. Federal rules have made these uncommon on residential mortgages and banned them outright on federal student loans. Check your loan agreement before you calculate.
Your payoff amount includes interest owed through the day you intend to pay off the loan, plus any fees not yet paid.2Consumer Financial Protection Bureau. What Is a Payoff Amount and Is It the Same as My Current Balance One thing it does not include: an escrow balance on a mortgage. Servicers aren’t required to credit escrow against the payoff. They typically refund the remaining balance by check within 20 business days after receiving your final payment.3Consumer Financial Protection Bureau. 12 CFR 1024.34 – Timely Escrow Payments and Treatment of Escrow Account Balances
Numbers You Need Before You Start
Pull these four figures from your most recent statement or online account portal.
- Current principal balance. The exact remaining balance after your last payment posted. Use the most recent figure, not one from a statement that’s several weeks old.
- Annual interest rate. This appears on your original loan agreement and usually on your current statement. Use the actual rate, not a rounded version.
- Day-count convention. Most consumer loans divide the annual rate by 365, or 366 in a leap year. Some commercial loans use a 360-day year, which produces a slightly higher daily rate. If your loan documents don’t specify, 365 is the safe assumption for mortgages, auto loans, and personal loans.
- Target payoff date. The specific date you expect the lender to receive your funds. Interest accrues until the money arrives, not when you send it. For most conventional mortgage loans, the lender charges interest up to but not including the day the payoff funds are received.4Fannie Mae. Processing Mortgage Loan Payments and Payoffs
Wired funds generally arrive the same business day. A mailed check adds several days of transit, and each of those days adds another day of interest. Pick your target date with that lag in mind.
The Formula, Step by Step
The core calculation is straightforward. You’re figuring out how much interest accumulates between now and your payoff date, then adding everything else you owe.
Step 1: Find your daily interest rate. Divide your annual rate by 365. An APR of 6% works out to 0.06 ÷ 365 = 0.00016438 per day.
Step 2: Calculate your daily interest charge. Multiply the daily rate by your current principal. On a $20,000 balance: 0.00016438 × $20,000 = $3.29 per day.
Step 3: Multiply by the days until payoff. Count from the day after your last payment posted through your target date. For 15 days: $3.29 × 15 = $49.32 in accrued interest.
Step 4: Add it all up. Principal balance + accrued interest + any fees or penalties = your payoff amount. In this example: $20,000 + $49.32 + $50 in fees = $20,099.32.
The math is simpler than it looks, but the margin for error is zero. If your payment arrives one day late, you’re short by one day’s interest and the lender won’t process it as a full payoff. Building in a buffer of a day or two on your target date is worth the few extra dollars.
Get the Lender’s Official Payoff Statement
Your own calculation is a useful estimate, but the lender’s official payoff statement is the binding number, and it catches fees or adjustments you might not know about. For mortgage loans, federal law requires the servicer to send you an accurate payoff statement within seven business days of receiving a written request.5Office of the Law Revision Counsel. 15 USC 1639g – Requests for Payoff Amounts of Home Loan The servicer can take longer only in limited circumstances, such as a loan in bankruptcy or foreclosure, a reverse mortgage, or a natural disaster.6eCFR. 12 CFR 1026.36 – Prohibited Acts or Practices and Certain Requirements for Credit Secured by a Dwelling
Most servicers accept payoff requests through an online portal, by phone, or by mail. The statement will carry a “good through” date, typically 10 to 30 days out. If your payment doesn’t arrive by that date, the statement expires and you’ll need a new one because additional interest will have accrued. The statement also provides wiring instructions or a mailing address for a physical check.
For auto loans, personal loans, and student loans, no single federal statute guarantees a turnaround time for payoff statements. Most lenders provide them within a few business days. Call and ask rather than assume.
Check Whether a Prepayment Penalty Applies
Borrowers often worry about prepayment penalties, but federal regulations have sharply limited where they can appear. For residential mortgages, CFPB rules prohibit prepayment penalties on any higher-priced mortgage loan. Even on qualifying fixed-rate mortgages where penalties are technically allowed, they’re capped at 2% of the prepaid balance during the first two years and 1% during the third year, and they’re banned after the third year.7Consumer Financial Protection Bureau. 12 CFR 1026.43 – Minimum Standards for Transactions Secured by a Dwelling A lender offering a loan with a prepayment penalty must also offer an alternative without one.
FHA, VA, and USDA mortgages prohibit prepayment penalties entirely. Federal student loans have been free of them since the Higher Education Act banned the practice. Most auto loans and personal loans don’t carry them either, though some subprime or specialty lenders still include them. The only way to know for certain is to read your loan agreement. Look for terms like “prepayment charge,” “early payoff fee,” or “yield maintenance” in the fine print, and add any applicable charge into Step 4 of the formula above.
