How much does 1% APR difference matter on a car loan?

On a $30,000 loan over 60 months, 1% APR difference costs about $780 in total extra interest (roughly $13/month). On a $50,000 loan, that same 1% difference is about $1,300 extra.

What credit score gets the best auto loan rates?

Generally, scores above 720 qualify for the best new car rates (under 5–6% APR in 2024–2025). Scores between 660–719 see rates of 6–9%, while scores below 660 often face double-digit rates.

Should I finance through the dealer or my bank?

Get pre-approved by your bank or credit union first, then compare with the dealer's offer. Dealers sometimes beat bank rates through manufacturer incentives, but may mark up rates for profit. Having an offer gives you negotiating power.

Why APR Comparison Matters for Car Loans

A seemingly small difference in APR can translate into hundreds or thousands of dollars over the life of a car loan. On a $35,000 loan over 60 months, the difference between 7.9% and 4.9% APR is over $2,700 in total interest.

Always compare the APR — not just the monthly payment — when evaluating loan offers. A longer loan term lowers monthly payments but increases total interest paid. Use this calculator to find the true cost difference between any two offers.

Getting pre-approved by your bank or credit union before visiting a dealer gives you a baseline rate to negotiate against manufacturer financing promotions.

Frequently Asked Questions

What's the difference between APR and interest rate?

APR (Annual Percentage Rate) includes the interest rate plus any fees rolled into the loan. For simple car loans with no fees, APR equals the interest rate. Always compare APRs when shopping.

When is 0% APR financing worth it?

0% APR is excellent if you would have financed anyway. However, manufacturers sometimes require full MSRP to qualify (no negotiation), so compare 0% APR at MSRP vs. a negotiated price with regular financing.
