Does Refinancing Your Car Loan Hurt Your Credit?

On this page

    The short answer: a little, temporarily. Refinancing involves a hard credit inquiry prior to funding the loan which typically drops your score slightly. That dip recovers within 3–6 months. For most borrowers, the interest savings from a lower rate far outweigh the temporary impact.


    What Happens to Your Credit When You Refinance

    Step 1: Rate check - no impact

    Checking your rate with Tenet is a soft inquiry. It doesn't appear on your credit report and doesn't affect your score. You can review real offers without any credit impact.

    Step 2: Full application - small, temporary impact

    If you proceed, a full application triggers a hard inquiry. This typically reduces your score by 5–10 points and shows on your report for two years, though the score impact fades within 3–6 months.

    Step 3: Account changes

    When your refinance closes, your old loan is marked "paid in full" (positive) and a new loan account is opened (initially shortens average account age — a minor negative). The net effect is usually small and temporary.


    Rate Shopping and the 14-Day Window

    Credit scoring models treat multiple auto loan inquiries within a short window as a single inquiry. The window is typically 14–45 days. In practice: comparing offers from multiple lenders within two weeks counts as one inquiry. Concentrate your applications within that window.

    Note: Some banks do not pull credit under the auto loan code but may use a general code, this can increase the impact to your credit. It's best to check offers only with soft credit and just do a hard credit inquiry with the lender you go with.


    When the Savings Outweigh the Impact

    A borrower with a $35,000 EV loan at 9% APR refinances to 5.75% with 36 months remaining:

    • Old loan remaining interest: ~$5,100
    • New loan total interest: ~$3,050
    • Interest saved: ~$2,050
    • Credit score impact: 4–5 months

    For almost every borrower, $2,050 in savings is worth a temporary dip.

    The calculation only goes the other way if your score is at a tipping point for something important, like a mortgage application, in the next few months. In that case, wait until after the mortgage closes.


    When to Avoid Refinancing

    • Major loan application coming up in 60-90 days. Delay until after.
    • Your score is already low and close to a lender minimum. Work on improving your score first.
    • Loan remaining principal balance. Tenet's minimum financed amount is $10,000, the savings on lower balances are also smaller.

    The EV-Specific Case for Refinancing

    EV owners benefit more from refinancing than gas-car owners because loan balances are higher. A 1.5% rate reduction saves more in absolute dollars on a $40,000 EV loan than on a $25,000 gas car loan. EV owners who refinanced in Q1 2026 saved an average of $209/month.

    Frequently Asked Questions

    How many points does refinancing drop my score?

    Typically 5–10 from the hard inquiry, plus a possible additional temporary dip from the new account. Combined effect: usually 10–20 points, recovering within 3-6 months.

    Can I refinance multiple times?

    Yes, but each involves a hard inquiry. Wait at least 12 months between refinances.

    Will refinancing affect my ability to get a mortgage?

    A hard inquiry from an auto refinance is a minor factor. More significant is the new monthly payment in your debt-to-income ratio. If you're applying for a mortgage within 60–90 days, the initial credit score impact may outweigh the lower debt-to-income ratio.


    One Last Thing

    There is a credit impact to refinancing but it is small and temporary. The interest savings are immediate and persist. For most EV owners with a rate above 6.5% on a balance over $15,000, the math clearly favors refinancing.

    Checking takes two minutes and costs nothing, not even to your credit score.
