Credit Karma is a free credit monitoring service — a website and app that shows you your credit scores and credit reports, updates them regularly, and makes money by recommending credit cards and loans to you based on what it sees. You don't pay. Lenders do, when you take one of the recommendations.
genuinely free, genuinely useful for watching your credit report, and genuinely misleading if you treat the number on the dashboard as your credit score. Use it as a monitoring tool. Don't use it as a prediction of what a lender will say.
What does Credit Karma actually give you for free?
Everything on the dashboard is free, with no paid tier and no card required. You get credit scores from two of the three major bureaus — TransUnion and Equifax — plus the underlying credit reports, a score simulator, an "Approval Odds" estimate on card and loan offers, and identity monitoring. There is no version of this you pay for.
| What you get | Details |
|---|---|
| Credit scores | VantageScore 3.0 from TransUnion and Equifax |
| Credit reports | Full reports from those same two bureaus |
| Experian | Not included — no score, no report |
| Score updates | Refreshed regularly, at no cost |
| Score simulator | Estimates the effect of a hypothetical action |
| Approval Odds | Estimated likelihood of approval before you apply |
| Cost to you | $0, no paid upgrade |
The catch: the score you see is not the score lenders use
Here is the part most reviews skip. Credit Karma shows you VantageScore 3.0. The scores that decide most lending decisions are FICO scores, which are built by a different company on a different model. Two different scoring systems reading the same credit file will not produce the same number, and neither one is "wrong."
Mortgages are the sharpest example. For decades, loans sold to Fannie Mae and Freddie Mac had to be underwritten on classic FICO scores — FICO 2 from Equifax, FICO 4 from TransUnion, FICO 5 from Experian. Those are old models, and none of them is the number on your Credit Karma dashboard.
In 2026 that changed: the Federal Housing Finance Agency cleared VantageScore 4.0 and FICO 10T for use in mortgage underwriting, ending the classic-FICO monopoly. Read quickly, that sounds like Credit Karma's score just became the mortgage score. It didn't. Credit Karma shows VantageScore 3.0. The newly approved model is VantageScore 4.0 — a different version, built on different data, including trended data that looks at how your balances moved over roughly the previous two years.
So when your Credit Karma score reads comfortably above a lender's stated minimum and the application still comes back a "no," nothing has malfunctioned. You compared a number from one model to a threshold set on another.
What Credit Karma is actually good at
Strip out the score anxiety and there's a real tool here.
- Watching your report for things that shouldn't be there. New accounts, new hard inquiries, a collection that isn't yours. This is the highest-value thing the app does, and the score model is irrelevant to it — an account that isn't yours is a problem on every model. Next step if you find one: how to dispute a credit report error.
- Tracking direction, not altitude. VantageScore 3.0 responds to the same fundamentals every model responds to: payment history, utilization, age, mix, new credit. If your Credit Karma number is climbing month over month, your FICO is very probably climbing too. The trend is trustworthy even when the level isn't.
- Reading your report without ordering one. Both full reports sit in the app, free, for as long as you keep the account. If you've never read one line by line, start here: how to read your credit report.
- Sanity-checking before you apply. Not the Approval Odds — the report itself. Check your utilization and look for a surprise derogatory mark before you hand a lender a reason to say no.
Where it falls down
Approval Odds are marketing, and the FTC has said so. In 2022 the Federal Trade Commission took action against Credit Karma over "pre-approved" claims, and the finalized order required the company to pay $3 million and stop making them. The FTC's complaint said the company told consumers they were "pre-approved" with "90% odds" for offers many of them didn't qualify for — and that almost a third of people shown a "pre-approved" offer who went through the trouble of applying were denied. Each of those denials was a hard inquiry on a real credit report.
Experian is missing. You get two bureaus, not three. Lenders routinely pull the one you can't see, and an error sitting on your Experian file is invisible here. Your legally guaranteed free reports from all three bureaus come from AnnualCreditReport.com — the federally authorized source — not from any app.
The simulator is an estimate of an estimate. It models what VantageScore 3.0 would do, which is already not the score a lender will use. Directionally useful. Not a forecast.
What a year with it actually looks like
In February the app flags a hard inquiry she doesn't recognise. She pulls the full report, finds a store card application she never made, freezes her files and disputes it. That single catch is worth more than everything else the app does all year.
Over the spring she pays her two card balances down from about 60% of her limits to under 20%, and her dashboard score climbs steadily. In September she applies for the car loan, and the dealer's lender pulls a FICO score of 712 — a different number from her dashboard's 731, on a different model, in the same neighbourhood.
Total cost for the year: $0. Actual benefit: a fraudulent application caught in February, and a clear view of whether her utilization work was landing. What she did not get was a reliable prediction of the lender's number — and she didn't need one, because she was fixing fundamentals rather than chasing a threshold.
Common mistakes
- Comparing your Credit Karma score to a lender's minimum. Different model, different version. The comparison isn't meaningful. Compare it to your own score last month instead.
- Applying because the odds looked good. Every application is a hard inquiry. Odds are advertising inventory; the issuer's published criteria are not.
- Checking daily and reading noise as signal. Scores move a few points when a statement posts. Monthly is plenty.
- Assuming three bureaus are covered. Experian isn't there. Get all three free at AnnualCreditReport.com.
- Opening a card from the offers feed to "build credit." A new account lowers your average account age and adds an inquiry. If building is the goal, start with how to build credit from scratch rather than the feed.
- Ignoring the report because the score looks fine. A good score with a stranger's collection account on the file is still a problem — and a much easier one to fix early.
Edge cases
You have a thin file or no credit history. VantageScore models are generally able to score thinner files than classic FICO models, so you may see a number here when a lender sees "insufficient history." That's not a score you can spend. Your real next step is secured credit card vs. credit-builder loan.
Your income is irregular. Nothing here models income — scores don't include it. What it can do is show rising utilization early, which is the first thing that slips in a thin month. Pair it with how to lower your credit card interest rate before the balance compounds.
You're actively rebuilding after collections or default. Use it for the report, not the score: watch that disputed items actually fall off and that settled accounts update to reflect the settlement. Background: what to do when a debt goes to collections.
You're applying for a mortgage in the next six months. This is the case where the score gap matters most. Open no new accounts, and get the number from the lender rather than the dashboard.
You've frozen your credit. A freeze doesn't block your own monitoring, and freezing remains one of the cheapest anti-fraud moves available: credit freeze vs. credit lock.
Who should skip Credit Karma
Skip it if the offers feed is going to pull you into applications you wouldn't otherwise make — for some people the cost of monitoring is a card they didn't need, and that's a bad trade at any price. Skip it if you already get a free FICO score and report alerts from your bank or card issuer, since you'd be adding a second dashboard that disagrees with the first for no benefit. And skip it entirely as a source of truth if you're within a few months of a mortgage application: get the number from the lender.
For everyone else — anyone who wants to watch their credit report for errors and fraud, and track whether their habits are moving the needle — it costs nothing, it does that job, and the honest limitation is that the headline number is a reasonable estimate rather than the figure anyone will lend against.
Quick answers
Is Credit Karma really free? Yes. There's no paid tier and no charge for scores, reports or monitoring. Credit Karma earns money by recommending credit cards and loans based on your credit profile and getting paid by the lender when you take one. You're not the customer — you're the audience.
Why is my Credit Karma score different from my real credit score? Because it's a different scoring model. Credit Karma shows VantageScore 3.0 from TransUnion and Equifax; most lending decisions use a FICO score, and mortgages have historically used older classic FICO versions. Different models weigh the same credit file differently, so the numbers rarely match. Neither one is fake.
Does checking Credit Karma hurt your credit score? No. Checking your own score or report is a soft inquiry, which has no effect on your score. What does affect it is applying for credit — including applying for an offer shown inside the app, which triggers a hard inquiry whether or not you're approved.
Can I trust Credit Karma's Approval Odds? Treat them as advertising. The FTC finalized an order in 2023 requiring Credit Karma to pay $3 million and stop making deceptive "pre-approved" claims, after alleging that many consumers shown such offers were denied when they applied. Use a lender's own prequalification tool instead — it uses a soft pull.
Is Credit Karma enough, or do I need all three credit reports? Not enough on its own. It covers TransUnion and Equifax, so nothing on your Experian file shows up. Get all three free at AnnualCreditReport.com, the federally authorized source, and use Credit Karma for ongoing monitoring between those pulls.
