Definition
An auto loan is a form of financing used to purchase a vehicle, in which the borrower repays the loan amount plus interest over a fixed term, with the vehicle generally used as collateral.
How Auto Loans Work
You borrow the amount needed to purchase the vehicle, minus any down payment or trade-in value, and repay that balance through equal monthly installments that include both principal and interest. The loan term, typically ranging from three to seven years, along with your interest rate, determines your monthly payment and the total cost of the loan.
Direct Financing vs. Dealer-Arranged Financing
| Type | How It Works | Key Consideration |
|---|---|---|
| Direct Financing | You get pre-approved directly from a bank, credit union, or online lender before visiting the dealership | Provides a rate benchmark for negotiating |
| Dealer-Arranged (Indirect) Financing | The dealer submits your application to one or more lenders and may mark up the rate | Convenient, but the "buy rate" from the lender may differ from what's offered to you |
According to the CFPB, getting one or more loan quotes from a bank or credit union before visiting the dealership puts you in a stronger negotiating position, since it gives you a real rate to compare against whatever the dealer offers.
What Determines Your Auto Loan Rate
- Credit score and credit history
- Loan term — shorter terms often carry lower rates but higher monthly payments
- New vs. used vehicle — used vehicle loans often carry higher rates than new vehicle loans
- Down payment and trade-in value — a larger down payment can reduce the amount financed
- Whether financing is arranged directly or through the dealership
Understanding Total Cost, Not Just the Monthly Payment
The CFPB's auto loan guidance emphasizes calculating the total cost of a loan, not just the monthly payment, using this relationship: Formula: Total Cost of Loan = (Monthly Payment × Number of Months) + Down Payment + Trade-In Value Applied A lower monthly payment doesn't necessarily mean a better deal — according to the CFPB, it might simply mean you're paying over a longer period, which can increase the total interest paid over the life of the loan.
Avoiding Negative Equity
Negative equity occurs when you owe more on the vehicle than it's currently worth, which becomes more likely the longer your loan term runs, since vehicles typically depreciate faster than a long loan term pays down the balance. According to the CFPB, longer loan terms increase the risk of negative equity for an extended period, which can create problems if you need to sell or trade in the vehicle before the loan is paid off.
Step-by-Step: Shopping for an Auto Loan
- Check your credit report for errors before shopping for financing.
- Get one or more loan pre-approvals from a bank or credit union before visiting the dealership.
- Set a budget that includes the loan payment plus insurance, maintenance, and fuel costs.
- Compare the total cost of competing loan offers, not just the monthly payment.
- If offered a better rate at the dealership, confirm the loan term and amount financed haven't changed.
- Ask questions about anything you don't understand before signing the final paperwork.
A Real-World Example
A buyer pre-approved for a $25,000 auto loan at 7% over 60 months from their credit union visits a dealership, which offers a lower monthly payment by extending the term to 72 months at a similar rate. While the monthly payment is lower, the total interest paid over the life of the loan increases because of the longer term. Comparing the total cost of both offers, rather than just the monthly payment, reveals which option is actually less expensive over time.
Common Mistakes
- Focusing only on the monthly payment instead of the total cost of the loan.
- Not getting a pre-approval before negotiating at the dealership.
- Choosing a longer loan term without understanding the increased risk of negative equity.
- Assuming a lower monthly payment offered at the dealership means a better overall deal.
- Not reviewing the final loan documents carefully before signing.
Expert Tips
- Get pre-approved by a bank or credit union before visiting the dealership to use as a negotiating benchmark.
- Ask for the total cost of the loan, not just the monthly payment, when comparing offers.
- Consider a shorter loan term if your budget allows, to reduce total interest paid and the risk of negative equity.
- Review your credit report for errors before applying, since inaccuracies could affect your quoted rate.

Frequently Asked Questions
Is it better to get pre-approved before going to the dealership?
Yes, according to the CFPB, getting a loan quote from a bank or credit union before shopping gives you a benchmark rate, which can help you negotiate a better deal or recognize if the dealer's financing isn't competitive.
Does a lower monthly payment always mean a better auto loan deal?
Not necessarily. A lower monthly payment may simply reflect a longer loan term, which can increase the total interest you pay over the life of the loan.
What is negative equity on a car loan?
Negative equity means you owe more on the loan than the vehicle is currently worth. It becomes more likely with longer loan terms, since vehicles typically depreciate faster than a long-term loan balance decreases.
Are used car loans more expensive than new car loans?
Used vehicle loans often carry higher interest rates than new vehicle loans, partly reflecting the vehicle's lower resale value and higher perceived risk to the lender.
