Why Do I Have Different Credit Scores? FICO vs. VantageScore, and the One Your Lender Uses

Quick answer: You have different credit scores because FICO and VantageScore use different formulas, each has several versions in use, the three credit bureaus don’t hold identical information about you, and every score reflects your report on the day it was pulled. Most mortgage lenders use Classic FICO Scores 2, 4 and 5 and take the middle one, which is why your lender’s number often comes in lower than your app.

Check your credit score in three places and you’ll probably get three different numbers. One app says 742, your credit card says 715, and the lender who pulls your credit for a mortgage comes back with 688. None of them is necessarily wrong. You don’t have one credit score. You have dozens, and each one is built for a different job.

After 38 years in mortgage lending, this is the question I hear most from buyers: “Why is my lender’s score lower than my app?” This guide explains where the differences come from, which scores lenders actually use, and how to see the one that matters before you apply.

The short answer

Your scores differ for four reasons:

1. Different scoring companies. FICO and VantageScore use different formulas.
2. Different versions. Each company has several versions in use at the same time, such as FICO Score 8, FICO Score 2 and VantageScore 3.0.
3. Different credit bureaus. Experian, Equifax and TransUnion don’t always hold the same information about you.
4. Different timing. Each score reflects your report on the day it was pulled. A balance reported yesterday can move it.

Small gaps of 10 to 30 points are normal. A gap of 50 points or more usually points to a difference in your credit reports, and that’s worth checking.

Reason 1: FICO and VantageScore are different companies

FICO created the first widely used credit score in 1989, and its scores are still used in most lending decisions. VantageScore was created in 2006 by the three credit bureaus as a competing model. Most free credit apps show a VantageScore, because it costs them less to display.

Both use the same 300 to 850 range on their main scores, and both weigh the same basic things: whether you pay on time, how much of your credit limits you’re using, how long you’ve had credit, new applications, and your mix of accounts. They weigh those factors differently, though. Two examples:

• Thin credit files. FICO generally needs an account that’s at least six months old and some activity in the last six months to produce a score. VantageScore can score people with less history, so someone new to credit may have a VantageScore and no FICO Score at all.
• Paid collections. Newer versions of both models ignore collection accounts that have been paid. Older versions, including the FICO versions most mortgage lenders still use, may still count them.

Reason 2: There are many versions, and lenders use different ones

FICO and VantageScore update their models every few years, but lenders don’t have to switch. Upgrading costs money and takes testing, so many lenders keep using older versions for years. That’s why several versions are in use at once.

So when your credit card shows a FICO Score 8 and your mortgage lender pulls FICO Score 2, you’re looking at two different formulas. The mortgage versions are older and tend to be stricter, which is a big reason buyers see a lower number at the lender.

Reason 3: The three credit bureaus have different information

Lenders aren’t required to report to all three bureaus. A credit card might report to Experian and TransUnion but not Equifax. A collection might show up at one bureau only. Even when every lender reports everywhere, they report on different days of the month.

That means the same scoring model can produce three different numbers. Your FICO Score 2 from Experian, FICO Score 4 from TransUnion and FICO Score 5 from Equifax are each built from a different report. This is why mortgage lenders pull all three.

If one bureau’s score is far lower than the others, pull your free reports at AnnualCreditReport.com and compare them side by side. Look for an account that appears on only one report, a late payment you don’t recognize, or a balance that’s wrong. Errors can be disputed for free with each bureau.

Reason 4: Scores change every time your report changes

A credit score isn’t stored anywhere. It’s calculated from your report at the moment someone asks for it. If your card issuer reports a $3,000 balance on the 5th and you pay it off on the 10th, a score pulled on the 8th will look worse than one pulled on the 12th.

The biggest short-term mover is your credit utilization, the share of your card limits you’re using. Paying cards down before the statement closing date, not just before the due date, is one of the fastest ways to raise the score a lender sees.

What is your “true” credit score?

There isn’t one true score. The number that matters is the one the lender you’re applying with will use. Scores shown in apps are sometimes called “educational” scores. They’re real scores from a real model, but they may not be the model your lender uses.

Think of it like this:

• Applying for a credit card? Your FICO Score 8 or a FICO Bankcard Score is the best guide.
• Buying a car? Look at FICO Auto Scores.
• Getting a mortgage? Look at your Classic FICO Scores (2, 4 and 5), and now VantageScore 4.0 as well.

Free scores are still useful. They move in the same direction as your lender scores, so they’re a good way to track progress. Just don’t expect the numbers to match.

Which credit score do mortgage lenders use?

For most conventional, FHA, VA and USDA loans, lenders pull all three Classic FICO Scores and use the middle one. If your scores are 702, 688 and 715, your qualifying score is 702. On a joint application, lenders typically use the lower of the two borrowers’ middle scores.

Fannie Mae and Freddie Mac now also accept VantageScore 4.0 for eligible loans. FHA will accept VantageScore 4.0 and FICO Score 10T for FHA case numbers assigned on or after January 1, 2027, under HUD Mortgagee Letter 2026-11. That can help people whose rent and utility history isn’t counted by the older FICO models. Your lender decides which model to use, so ask before you apply.

Your qualifying score affects more than approval. It sets your interest rate and, on conventional loans, your mortgage insurance cost. Moving from 678 to 680 or from 738 to 740 can change your pricing. See the minimum credit scores for each loan type.

How to raise every version of your score at once

Because all the models look at the same core behavior, the same habits help every score:

• Pay every bill on time. Payment history carries the most weight in every model.
• Keep card balances low, ideally under 10% of each limit when you’re about to apply.
• Don’t close your oldest cards. They anchor the age of your credit.
• Limit new applications in the six months before a mortgage.
• Fix report errors early. Disputes can take 30 days or more.

Frequently asked questions

Why do I have different credit scores?

Because different companies (FICO and VantageScore) score you with different formulas and versions, the three bureaus may hold different data, and each score is a snapshot from a different day. Gaps of 10 to 30 points are normal; 50 or more usually means your reports differ.

Why is my Credit Karma score different from my FICO Score?

Credit Karma shows VantageScore 3.0, which uses a different formula than FICO. It also only uses your TransUnion and Equifax reports. Differences of 20 points or more between the two are common.

Why is my mortgage credit score lower than my app?

Mortgage lenders use older Classic FICO versions (2, 4 and 5) that are often stricter than the FICO 8 or VantageScore you see in apps. They also use the middle of your three scores.

How many credit scores do I have?

Dozens. Each combination of scoring model, version and credit bureau produces its own number. FICO alone has more than 25 versions in use.

Which credit score is the most accurate?

They’re all accurate for what they measure. The one that matters is the one your lender uses. For a mortgage, that’s usually your middle Classic FICO Score. Compare credit score sites here.

Does checking my own score hurt it?

No. Checking your own score is a soft inquiry and never affects your score. Only applications for new credit cause hard inquiries.
