    If your Credit Karma score says one thing and a lender or card issuer shows another, you are probably looking at two different scoring models. This guide explains the difference in plain English, using official FICO, VantageScore, and CFPB material, and gives you a short checklist for when your Credit Karma score drops.

    What FICO and VantageScore are

    FICO and VantageScore are companies that build credit scoring models. A model is a formula that turns the information in one credit report into a number.

    FICO describes its scores as based on five categories of credit report information: payment history, amounts owed, length of credit history, new credit, and credit mix. VantageScore describes similar factors, such as payment history, credit utilization, and credit age, and explains them by level of influence.

    Each company has released several versions over time. A FICO Score 8 and a FICO Score 10 are different, just as VantageScore 3.0 and 4.0 are different. For FICO's versions, see FICO score versions explained. For a deeper model comparison, see our FICO vs. VantageScore comparison.

    Why your Credit Karma score is different from FICO

    Different model: Credit Karma's own product pages say it offers VantageScore 3.0 scores. A lender may use a FICO Score instead.

    Different bureau: Credit Karma uses TransUnion and Equifax data. A lender may use Experian, or all three. Not every creditor reports to every bureau.

    Different date: Each score reflects the report on the day it was calculated. A card balance that reported last week can change the number.

    Different purpose: Lenders may use industry-specific scores, such as scores built for auto or card lending. The CFPB notes that scores vary depending on the model and data used.

    My Credit Karma score dropped—what should I check?

    A score change usually means something in the report changed. Open the report behind the score that dropped (TransUnion or Equifax) and look for what's new.

    Common things to check: a higher reported card balance, a new account, a new hard inquiry, a late payment, a collection, or a closed account. Our why did my credit score drop guide covers these in more detail.

    If you see something you don't recognize or believe is wrong, compare all three reports from AnnualCreditReport.com, then consider a dispute. See how to dispute something you see on Credit Karma.

    Which score should you care about?

    The one the lender will use. If you're applying for something, ask the lender which score and which bureau it uses.

    If you are denied or offered worse terms because of a credit score, the lender's notice can include the score used and the bureau that provided the report. That is the most reliable way to know which score affected a decision.

    Since every score comes from report data, keeping your reports accurate helps no matter which model is used. You can scan my credit report with a free, step-by-step review that helps you find entries worth a closer look.

    Frequently asked questions

    They are competing scoring models from different companies. Both use your credit report, but they weigh and describe factors differently and come in multiple versions, so the same report can produce different numbers.

    Credit Karma shows VantageScore 3.0 from TransUnion and Equifax. A FICO Score uses a different formula and may use a different bureau or date, so the numbers often differ.

    Neither is the one true score. Each is an accurate output of its own formula. What matters is which score the lender you care about uses, and whether the report data is correct.

    Usually because something on your TransUnion or Equifax report changed, such as a higher balance, a new inquiry or account, or a late payment. Review the report behind the score that dropped.

    Some do. Lenders choose their own models, and many use FICO Scores. Ask the lender, or read the notice it sends if you're denied.

    What to gather first

    • A current copy of each credit report you want to review (Equifax, Experian, TransUnion) from AnnualCreditReport.com.
    • Government-issued photo ID and proof of current address, which bureaus commonly request with a mailed dispute.
    • Account statements, payment records, or letters that relate to the item you believe is inaccurate or incomplete.
    • The exact account name, partial account number, and the reason you believe the entry is inaccurate or incomplete.
    • A way to keep records: copies of what you send and, if mailing, proof of delivery.

    Common mistakes to avoid

    • Disputing information you know is accurate — that wastes the process and does not help you.
    • Sending a vague dispute. Identify the specific item and explain what is inaccurate or incomplete.
    • Disputing with only one bureau when the same entry appears on more than one report.
    • Keeping no copies of what you sent, so you cannot show what was disputed or when.
    • Paying a company that promises deletions or score increases — no one can promise those outcomes.

    When to get additional help

    Consider additional help if a bureau or furnisher does not respond, if an entry you believe is inaccurate stays on your report after a reinvestigation, if you may be affected by identity theft, or if you have questions about your legal rights.

    How this free tool can help

    A free, AI-assisted report scan reviews a credit report you upload and highlights entries that may be inconsistent, incomplete, or worth a closer look. If you decide an item may be inaccurate or incomplete, it can draft a dispute letter you can review, edit, and send yourself.

    This tool is not a law firm, credit bureau, lender, or credit-repair organization. It does not provide legal advice and does not guarantee deletions, dispute outcomes, or changes to your credit scores. You decide what to dispute and you send every letter.

    Important limitation

    Credit reporting disputes should be based on information you believe may be inaccurate, incomplete, unfamiliar, or improperly reported. Do not dispute information you know is accurate. A dispute does not guarantee a deletion, correction, score change, or other result.
