# Why Your Credit Karma Score Is Different From What Your Lender Sees

> You checked the app, saw a number you liked, then the lender came back lower. Nothing went wrong. The two numbers come from different formulas, and once you know which one a lender pulls, you can see it before you apply.

Your Credit Karma score is usually different from what your lender sees because they're not the same score. Credit Karma shows a VantageScore 3.0 built from your TransUnion and Equifax files. Most lenders, and nearly all mortgage lenders, pull a FICO score instead, often an older version picked for that type of loan, and sometimes from a bureau the app doesn't use at all. Same person, same history, different formula.

That's the **Credit Karma score vs lender** gap in a nutshell. What's less obvious is how big it can get, which way it tends to go, and how to see the lender's number before you apply.

For the record: Credit Karma isn't wrong. It's a useful free tool, and its scores are calculated from real bureau data. It just answers a slightly different question than the lender is asking.

## The four reasons the numbers don't match

### 1. Different model

This is the big one. VantageScore and FICO are competing scoring systems. Both read a credit report, both land on a 300 to 850 scale, and both care most about payment history and how much of your available credit you're using. But they weigh things differently, they treat some items in opposite ways, and they disagree about who can be scored at all.

A few concrete differences:

- **Thin files.** FICO generally won't score someone without an account at least six months old and some activity reported in the last six months. VantageScore 3.0 can score people with much shorter histories. If your credit is new, the app may show a number while a FICO-based lender gets "unscorable" or a low score.
- **Paid collections.** VantageScore 3.0 ignores collections that have been paid off. Older FICO models, including the ones mortgage lenders use, still count them. A paid-off collection from an old phone bill can cost you points at the bank that it doesn't cost you in the app.
- **Utilization and trends.** Both penalize high card balances, but they draw the lines in different places, so a $3,800 balance on a $5,000 limit can hit one model harder than the other.

We compare the two families in detail in [FICO vs. VantageScore](https://phonenumbercreditscore.com/blog/fico-vs-vantagescore).

### 2. Different version

"FICO score" isn't one thing either. [According to myFICO](https://www.myfico.com/credit-education/credit-scores/fico-score-versions), FICO Score 8 is the most widely used version, but mortgage lenders use FICO Score 2 from Experian, FICO Score 5 from Equifax and FICO® Score 4 from TransUnion. Auto lenders often use FICO Auto Scores, and card issuers may use FICO Bankcard Scores. Those industry versions run on a 250 to 900 scale, so a "780" from an auto lender doesn't mean the same thing as a 780 in an app.

### 3. Different bureau

Credit Karma pulls from TransUnion and Equifax. If a lender pulls Experian, it's reading a file the app has never shown you. Lenders don't have to report to all three bureaus, so it's normal for one file to be missing a card or a loan that another has. One missing paid-off auto loan can move a score noticeably.

### 4. Different day

Card balances get reported once a month, usually around the statement date. If you paid a card down on the 3rd and the app refreshed on the 1st, you and the lender are looking at different balances. Same goes for a new account that hasn't hit every file yet.

## A worked example: Marcus and the mortgage

Marcus Bell (fictional) checks his app the week before talking to a loan officer. It shows 742 on TransUnion and 736 on Equifax. He figures he's comfortably in "very good" territory.

The loan officer pulls a tri-merge report, the standard for a conventional mortgage, and gets:

| Bureau | Model | Score |
|---|---|---|
| Experian | FICO Score 2 | 701 |
| Equifax | FICO Score 5 | 712 |
| TransUnion | FICO Score 4 | 695 |

For a single borrower, mortgage lenders typically use the middle of the three, so Marcus is priced at 701. Forty points below what he expected.

Nothing sinister happened. He had a collection from an old internet bill, paid off in 2021, that VantageScore 3.0 ignores and the classic FICO models still count. His Experian file also showed a store card at 88% of its limit from before he paid it down. The other two files had already picked up the lower balance. Two ordinary quirks, stacked.

On a $320,000 loan, the gap between pricing tiers can mean a noticeably higher rate or extra points at closing. That's why we tell people to look at the score the lender uses before they shop, not after.

## Credit Karma score vs lender score: how common is a gap?

More common than you'd guess. In a 2012 study comparing the scores consumers buy with the scores lenders use, the CFPB found that [about one in five consumers would likely get a meaningfully different score](https://www.consumerfinance.gov/archive/newsroom/consumer-financial-protection-bureau-study-finds-credit-scores-used-by-consumers-and-lenders-can-differ/) than a lender would. For most people the numbers land within a band of each other. For a meaningful minority they don't, and you usually can't tell in advance which group you're in.

There's no single direction, either. Some people's FICO scores come in higher than their app scores. The usual suspects for a lower FICO are thin files, paid collections, and recent lates, but it varies by file.

## What about the newer mortgage scores?

You may have read that mortgages are moving to newer models. In October 2022 the Federal Housing Finance Agency validated FICO 10T and VantageScore 4.0 for loans sold to Fannie Mae and Freddie Mac, and announced a plan to require them eventually. As of this writing, though, lenders are still pulling the classic FICO 2, 5 and 4 for conventional loans, and the transition timeline has shifted more than once. If you're applying in the near term, the classic scores are the ones that matter.

## How to know your lender's number before you apply

**Find out which score the lender uses.** Just ask. A loan officer, a dealer's finance manager or a card issuer's support line will usually tell you which model and bureau they pull. "FICO, TransUnion" is a perfectly normal answer.

**Get that specific score.** For mortgages, that means the classic FICO versions. FICO sells them directly through myFICO. You can also see the TransUnion one, FICO Score 4, through a [phone number credit lookup](https://phonenumbercreditscore.com/) on yourself. It's a soft pull, so it doesn't touch your score.

**Read your reports, not just the scores.** The free reports at [AnnualCreditReport.com](https://www.annualcreditreport.com/index.action) show what's actually on each bureau's file. If one bureau is missing an account or showing an old balance, that's often the whole explanation. Our guide to [credit report vs. credit score](https://phonenumbercreditscore.com/blog/credit-report-vs-credit-score) explains what to look for.

**Time your balances.** If you're about to apply, pay cards down before the statement date, not after, so the low balance is what gets reported. Utilization is one of the fastest things to move. See [how credit utilization works](https://phonenumbercreditscore.com/blog/credit-utilization-explained) for the details.

**Don't panic about rate shopping.** FICO treats multiple mortgage or auto inquiries within a short window as a single inquiry, so comparing a few lenders in the same couple of weeks won't stack up damage. The mechanics are in [soft pull vs. hard pull](https://phonenumbercreditscore.com/blog/soft-pull-vs-hard-pull).

## If you're the one doing the checking

Landlords, brokers and dealers hear it constantly: "But Credit Karma says I'm a 720." The applicant isn't lying. They're quoting a different score. It helps to say so plainly, and to explain which score you use and why.

That's a big part of why our lookups return FICO Score 4 specifically. It's the score TransUnion's mortgage pull produces, calculated by FICO, rather than an educational score. When a [mortgage loan officer pre-qualifies a lead](https://phonenumbercreditscore.com/blog/mortgage-loan-officer-lead-qualification) or a landlord checks an applicant, the number matches the world lenders live in. There's a side-by-side table on our [why FICO 4](https://phonenumbercreditscore.com/why-fico-4) page.

You still need a permissible purpose for every lookup, and the cleanest one is the person's written OK. If you're checking someone else, our [credit check consent template](https://phonenumbercreditscore.com/blog/consumer-consent-credit-check) makes that part easy.

## What the app is still good for

None of this means you should delete the app. Free monitoring is genuinely useful. It'll tell you when a new account opens in your name, when a balance jumps, or when a collection appears. Trends matter more than the exact number: if your VantageScore climbs 40 points over six months, your FICO scores almost certainly improved too.

Just don't walk into a mortgage application quoting it. Look up the score the lender will see, read all three reports, and fix what you can a month or two ahead. When a score surprises someone, the reason is usually sitting right there in the file.

## Frequently asked questions

### Is Credit Karma accurate?

Yes, for what it shows. Credit Karma displays VantageScore 3.0 scores calculated from your TransUnion and Equifax files. Those are real scores from real data. They just aren't the models most mortgage and many auto lenders use, so the numbers often differ from what a lender pulls.

### Is my FICO score always lower than my Credit Karma score?

No. It can be higher or lower. The direction depends on what's in your file. Thin files, paid collections and recent late payments are common reasons the FICO number comes in lower, but plenty of people see the opposite.

### Which score do mortgage lenders use?

For most conventional mortgages, lenders pull three classic FICO scores: FICO Score 2 from Experian, FICO Score 5 from Equifax and FICO Score 4 from TransUnion. For a single borrower with three scores, the middle one is usually the score used for pricing.

### Will checking my FICO score before applying hurt my credit?

No. Checking your own score is a soft inquiry and never affects it. Only the hard inquiry when you actually apply can have a small, temporary effect.
