Yes, a car loan counts as debt. It is a legally binding obligation that appears on your credit report as an installment account, and the monthly payment is included in the debt-to-income ratio lenders use when you apply for a mortgage or any other new credit. How much that matters depends on the size of your payment relative to your income, how long you have left on the loan, and whether you are carrying negative equity from a previous vehicle.
How a Car Payment Changes Your Debt-to-Income Ratio
Lenders calculate your debt-to-income ratio by dividing your total monthly debt payments by your gross monthly income. The car payment counts in full, no matter how much of it goes to interest versus principal. A $500 car payment on $5,000 of gross monthly income adds ten percentage points to your DTI by itself.
That number carries the most weight when you apply for a mortgage. Federal rules require mortgage lenders to make a good-faith determination that you can actually repay the loan before approving you.1eCFR. 12 CFR 1026.43 – Minimum Standards for Transactions Secured by a Dwelling The federal qualified-mortgage standard no longer sets a fixed DTI cap; it switched to a price-based threshold in 2022.2Federal Register. Qualified Mortgage Definition Under the Truth in Lending Act Regulation Z General QM Loan Definition Most lenders still apply their own internal DTI limits, commonly in the range of 43 to 50 percent. A large car payment can push you past those thresholds and shrink the mortgage amount you qualify for.
How a Car Loan Shows Up on Your Credit Report
Credit bureaus classify a car loan as an installment account: a fixed loan with a set number of payments, rather than revolving credit like a credit card. The report shows both your original balance and the current remaining balance, so scoring models can track how consistently you are paying it down. Having an active installment loan also contributes to your credit mix.
Federal law requires lenders that report to credit bureaus to provide accurate and complete information. If a lender finds that the data it submitted is wrong, it must promptly notify the bureau and correct the error.3Office of the Law Revision Counsel. 15 USC Chapter 41 Subchapter III – Credit Reporting Agencies This covers both on-time payments and missed payments or defaults.
Adverse information, such as a severely late payment that leads to collection activity, can stay on your credit report for up to seven years from the date the delinquency began.4Office of the Law Revision Counsel. 15 USC 1681c – Requirements Relating to Information Contained in Consumer Reports On the other side, consistent on-time payments build a positive payment history that helps your score for as long as the account remains on the report.
When Negative Equity Makes the Debt Bigger Than the Car
Trading in a car you still owe money on can quietly amplify the DTI problem. When the trade-in is worth less than your remaining loan balance, dealers often roll that negative equity into the new loan. A Consumer Financial Protection Bureau study found that borrowers who financed negative equity from a prior loan had average monthly payments of $626, compared to $493 for borrowers with no trade-in, roughly 27 percent higher. Those borrowers started with an average loan-to-value ratio of about 119 percent, meaning they owed more than the car was worth before driving it off the lot.5Consumer Financial Protection Bureau. Negative Equity in Auto Lending
The higher monthly payment that results from rolled-in negative equity feeds straight into your DTI ratio and can limit your borrowing ability for years. If a mortgage application is anywhere on the horizon, rolling negative equity into a new car loan is one of the common ways borrowers quietly reduce their own purchasing power.
What Happens If You Fall Behind
A car loan is secured debt, with the vehicle itself serving as collateral. If you stop making payments, the lender can repossess the vehicle without going to court first, as long as the repossession happens without a breach of the peace: no physical confrontation, no threats, no entry into a locked garage.6Cornell University Legal Information Institute (LII). UCC 9-609 – Secured Partys Right to Take Possession After Default Most auto loan contracts include a grace period of roughly 10 to 15 days after the due date before late fees apply, with the repossession process beginning sometime after that.
Repossession does not necessarily end the debt. The lender sells the vehicle, and if the sale price does not cover what you owe, including towing, storage, and sale-preparation fees, the remaining amount is called a deficiency. In most states, the lender can sue you for a deficiency judgment to collect it. If you owe $15,000 and the lender sells the car for $8,000, you could still be on the hook for $7,000 plus repossession fees.7Federal Trade Commission. Vehicle Repossession A repossession also creates a severe negative mark on your credit report that can follow you for up to seven years.4Office of the Law Revision Counsel. 15 USC 1681c – Requirements Relating to Information Contained in Consumer Reports
The Debt Counts Against a Co-Signer Too
If someone co-signs the loan, that person takes on the full legal obligation to repay the debt if you stop paying. Co-signing does not give the co-signer any ownership of the vehicle; the role is purely to guarantee the loan.8Federal Trade Commission. Cosigning a Loan FAQs Under the FTC’s Credit Practices Rule, the lender must give the co-signer a written notice plainly stating that the creditor can collect from the co-signer without first trying to collect from the primary borrower, and can use the same methods, including lawsuits and wage garnishment, against the co-signer as against the borrower.9eCFR. 16 CFR Part 444 – Credit Practices
The full monthly car payment also shows up on the co-signer’s credit report as a debt obligation. That raises their DTI when they apply for their own loans, and a default by the primary borrower will damage both parties’ credit scores because the late payments appear on both reports.
Ways to Reduce the DTI Impact
Only the monthly payment, not the total balance, feeds into DTI. Anything that lowers your required payment improves the ratio.
- Refinance to a lower interest rate or a longer term. Both reduce the monthly payment, though a longer term usually means paying more total interest.
- Make extra payments toward principal. This does not change the required monthly payment, but it shortens the loan and gets you to payoff sooner, after which the payment drops out of your DTI entirely.
- Pay off the loan before applying for a mortgage. If you are close to the end of the loan, finishing it off before the mortgage application removes the payment from your DTI calculation.
- Avoid rolling negative equity into a new loan. Pay down the old loan first, or wait until you have positive equity, so the next payment reflects only the new car.
Your contract and state law decide whether paying off the loan early carries any penalty. Some lenders include a prepayment fee to recoup lost interest, though many do not.10Consumer Financial Protection Bureau.

A New Tax Deduction for Car Loan Interest
Starting with the 2025 tax year, a new federal deduction lets you write off interest paid on a personal car loan. The provision, enacted as part of Public Law 119-21, creates a category called Qualified Passenger Vehicle Loan Interest and applies to tax years 2025 through 2028.11Federal Register. Car Loan Interest Deduction Before this law, interest on a personal car loan was not deductible at all.
To qualify, the loan must meet several conditions. The vehicle must be new, with its original use starting with you; used cars do not qualify. Final assembly must have occurred in the United States, which you can verify from the plant-of-manufacture code in the VIN or the vehicle’s label. You must expect to use the car for personal purposes more than 50 percent of the time. The loan must have been taken out after December 31, 2024, and must be secured by a first lien on the vehicle.
The maximum deduction is $10,000 per tax return per year, regardless of filing status, so a married couple filing jointly shares that single $10,000 cap. The deduction phases out based on modified adjusted gross income, shrinking by $200 for every $1,000 of income above $100,000 for single filers (or $200,000 for joint filers), and disappearing entirely at $150,000 single or $250,000 joint.11Federal Register. Car Loan Interest Deduction You must include the vehicle’s VIN on your tax return to claim it. You do not have to itemize; the deduction is available even if you take the standard deduction.
If you also use the vehicle for business, the interest allocable to business use remains deductible as a business expense, separate from the new personal-use deduction. You cannot claim the same interest under both provisions, but you can split the interest between business and personal portions if you use the vehicle for both.11Federal Register.
