How to Get a Lower Interest Rate on a Car Loan
May 31, 2026
The interest rate on your car loan is one of the biggest levers on what the car actually costs you. A rate a couple of points lower can save thousands over the life of the loan. The good news is that the rate you are offered is not fixed — several things within your control influence it.
1. Improve your credit before you apply
Your credit score is the single biggest factor in the rate you are offered. If your purchase is not urgent, a few months of on-time payments, paying down credit-card balances, and correcting any errors on your credit report can move you into a better tier. See how your credit score affects your auto loan rate for the typical ranges.
2. Put more money down
A larger down payment reduces the lender’s risk and the amount you finance, which can earn a better rate and certainly lowers your payment. It also reduces the time you spend owing more than the car is worth. Our guide on how much to put down covers the rule of thumb.
3. Choose a shorter term
Lenders often charge higher rates on longer loans because they carry more risk. A shorter term usually means a lower APR and far less total interest — though a higher monthly payment. Weigh the trade-off in how to choose a loan term.
4. Get preapproved and compare multiple lenders
This is the step most people skip, and it is the most powerful. Getting preapproved by several lenders — banks, credit unions, and online lenders — lets you see who offers the lowest APR. Multiple auto-loan inquiries within a short window count as a single inquiry for scoring, so shopping around does not meaningfully hurt your credit.
Credit unions in particular are often worth a look, as they frequently offer competitive auto rates to members.
5. Let the dealer compete
If you arrive with a preapproval, you can ask the dealer to beat it. Sometimes manufacturer financing can — see dealership vs. bank financing. If they cannot, you already have your loan. Either way, you win.
6. Consider the car itself
New cars usually finance at lower rates than used ones, and certified pre-owned vehicles sometimes qualify for near-new rates. If the rate gap is large, factor it into the new vs. used decision.
7. Add a creditworthy cosigner (carefully)
If your own credit is thin or low, a cosigner with strong credit can lower your rate — but make sure both of you understand the responsibility involved.
The bottom line
You influence your car-loan rate through your credit, your down payment, your term, and — above all — by comparing several lenders instead of taking the first offer. Even a one- or two-point reduction adds up to real money over the term. Model a few rate scenarios in the calculator to see the dollar difference, then shop your loan around before you sign.
