Your credit score is one of the most important numbers in a car purchase. It determines your interest rate, which directly affects your monthly payment and the total cost of your loan. A 100-point difference can mean thousands of dollars.
Credit score tiers and approximate rates
- 720+ (Excellent) — Best rates, often 5–6%, or manufacturer 0% APR deals
- 680–719 (Good) — Slightly above average, typically 6–8%
- 640–679 (Fair) — Higher rates, 9–13%, limited promotional access
- 580–639 (Poor) — Subprime rates, 14–18%, may need a co-signer
- Below 580 (Very Poor) — Limited options, rates can exceed 20%
The real cost of a lower score
On a $30,000 loan over 60 months, the difference between 6% and 16% is roughly $8,200 in total interest. That is money going to the lender — not the car — purely because of your credit score.
What lenders actually look at
- Payment history (35%) — Late payments hurt more than anything else
- Credit utilization (30%) — Keep balances below 30% of each card limit
- Length of credit history (15%) — Longer history helps
- Credit mix (10%) — Having both cards and installment loans helps
- New inquiries (10%) — Multiple hard pulls in a short window hurt temporarily
How to get approved with bad credit
- Larger down payment — Reduces lender risk and can offset a lower score
- Co-signer — Someone with good credit co-signing can unlock better rates
- Credit unions — More flexible underwriting, especially for members
- Avoid buy-here pay-here dealers — Rates are extremely high; use only as a last resort
How to improve your score before applying
- Pay credit card balances below 30% of the limit on each card
- Do not open new credit accounts in the 3 months before applying
- Dispute errors on your credit report — check all three bureaus at AnnualCreditReport.com
- Do not close old accounts — length of history matters
- Make every payment on time in the months leading up to your purchase
Rate shopping tip
All auto loan inquiries within a 14–45 day window count as a single inquiry on your credit report. Get all your pre-approvals in the same two-week period to minimize score impact.
Check your credit before the dealer does
Pull your own report at AnnualCreditReport.com before any dealer runs your credit. Checking yourself is a soft pull — it does not affect your score. Knowing your number prevents surprises and gives you time to dispute any errors in advance.
