FICO Score vs. VantageScore: What’s the Difference and Why Your Numbers Don’t Match

Who created FICO and VantageScore?

A credit score is a three-digit number. The bank uses it to estimate whether you will pay on time. This number is not stored at the bureau ready-made. A formula calculates it from scratch every time. This formula is called a scoring model.

FICO was created by an American company called Fair Isaac. The first FICO score for all types of credit came out in 1989. Since then, it has been the main standard for US banks. When someone at a bank says “FICO score,” this is the formula they mean.

VantageScore came out in 2006. It was created jointly by the credit bureaus themselves: Experian, Equifax and TransUnion. Its main selling point is that it can calculate a score even for people with a very short history.

The key is not to mix up the model and the bureau. A bureau is a data warehouse: your cards, payments and debts. A model is a calculator that turns that data into a number. We cover the bureaus in detail in our article on how Experian, Equifax and TransUnion differ.

Why does one person have dozens of different scores?

Picture three kitchens and several recipes. The ingredients are the same, but the dishes come out different. It is the same with scores: three bureaus and many formula versions, and one person ends up with dozens of numbers.

• Regular FICO: FICO 8 (the version banks use most often), FICO 9, FICO 10 and 10T. The scale is 300–850.
• Mortgage FICO: FICO 2 from Experian, FICO 5 from Equifax, FICO 4 from TransUnion. These versions are old, but mortgages were scored with them for years.
• Special FICO for each type of credit: FICO Auto Score for car loans, FICO Bankcard Score for credit cards. The scale is wider: 250–900.
• VantageScore 3.0 and 4.0: the scale is 300–850. These are the scores free apps show most often.

Each version is calculated for each of the three bureaus. So on the same day you can have 690, 705 and 722, and all three numbers are correct.

What is the difference between FICO and VantageScore in practice?

Both models look at the same things: how you pay, how much you owe, how old your history is and how many new applications you have. But they differ in the details. Here are four differences that move the number.

How much history you need for your first score

For your first FICO score to appear, you need at least one account that is about 6 months old or older. And the bank has to report it to the bureaus. VantageScore can give you a number much sooner, sometimes a month or two after your first card. That is why newcomers already see a score in their app, while the bank says, “You don’t have a FICO score yet.”

Paid collections

A collection is a debt that was handed over to a collection agency. Let’s say you paid it. After that, FICO 9, FICO 10/10T, VantageScore 3.0 and 4.0 stop counting it. But FICO 8 and mortgage FICO scores keep counting it. Learn more in our article on why paying off a collection doesn’t fix your credit history.

Medical debt

VantageScore 3.0 and 4.0 do not count medical collections at all, whether paid or unpaid. FICO 9 and 10 count unpaid medical debt, but less harshly than other debt. And FICO 8 and the mortgage versions treat it like any other collection. One more thing: for several years now, the bureaus themselves have not shown medical collections under $500 on credit reports.

Several checks in a row when you shop for a car or a mortgage

When you apply, the bank does a hard inquiry: it looks at your credit history. If you are shopping for a car loan or a mortgage, you may get several of these checks in a row. FICO counts them as one if they fall within a window of 14 to 45 days, depending on the version. VantageScore’s window is shorter: 14 days. Learn more in our breakdown of hard inquiries.

Which score does the bank check for a credit card, a car loan and a mortgage?

There is no single rule. Each bank chooses both the bureau and the model. In mortgages, the company that gives you the loan is usually called the lender, and it makes this choice on its own too. But some options come up most often.

The most reliable way is simply to ask. At Excalibur Credit Solutions, we recommend doing this before you apply. The bank, or the loan officer handling your mortgage, will usually tell you the model and the bureaus without any fuss. For a car loan, it helps to get a pre-approval ahead of time. How to do it without extra credit checks is covered in our guide car loan pre-approval.

Why does Credit Karma show a higher score than the bank (or a lower one)?

Credit Karma is a popular free app. It shows VantageScore 3.0 based on data from two bureaus: TransUnion and Equifax. But banks more often check FICO. And they often look at the third bureau, Experian, whose data Credit Karma does not have.

Where Credit Karma gets its data

Excalibur Credit Solutions clients often come to us asking: why does Credit Karma show one number and the bank another? Usually the reason is one of these:

• You have a paid collection. VantageScore 3.0 doesn’t see it, but FICO 8 and mortgage FICO scores do.
• Your history is short. VantageScore has already calculated a score, but FICO hasn’t yet, or it scores you more cautiously.
• Experian has an entry that the other two bureaus don’t. The app simply doesn’t show it.
• The data was updated on different days. The app updates about once a week, while the bank sees your report as of today.
• High utilization: you are using a large part of your card limits. Different models react to this more or less strongly.

A difference of a few dozen points is normal. If the gap is bigger, open your full three-bureau report and find the entry that is pulling your FICO score down.

What changed with mortgages in 2025–2026?

For many years, regular mortgages in the US were scored only with classic FICO. The rules here are set by Fannie Mae and Freddie Mac. These are two government-sponsored companies that buy a huge share of regular mortgages from banks. In 2025, the agency that oversees them allowed lenders to also use VantageScore 4.0. And starting September 9, 2026, any lender approved by Fannie Mae and Freddie Mac can use it. No separate approval is needed anymore.

• The lender picks one model for the loan: classic FICO or VantageScore 4.0.
• If there are several borrowers (for example, a married couple), everyone is scored with the same model.
• Classic FICO is not going anywhere: many lenders still use it for now.
• FHA (a government mortgage program with a down payment as low as 3.5%) will start accepting VantageScore 4.0 and FICO 10T on January 1, 2027.

For immigrants with a short history, this is potentially good news. VantageScore 4.0 can calculate a score where classic FICO still has nothing to say. But as of 2026, no one can tell you in advance which model your lender will pick. How a lender looks at your score together with your income and debts is covered in our guide mortgages and DTI.

Which score should you trust, and what should you check before applying?

You can trust all of them: each number is honestly calculated by its own formula. What matters for the decision is something else: which score the bank will check for your goal. Before a big application, go through these steps:

1. Decide what you need: a card, a car or a mortgage. The model depends on it.
2. Ask the bank or the loan officer which model and which bureaus they check.
3. Order a report with scores from all three bureaus, for example through SmartCredit, IdentityIQ or MyScoreIQ. This way you will also see the Experian data that Credit Karma doesn’t have.
4. At each bureau, check for collections, late payments and entries that aren’t yours. You can dispute an error in your report.
5. If you are applying soon, pay down your cards before the statement date so your utilization is low.
6. Don’t apply for new cards or loans for 6–12 months before a mortgage (at the very least, the last 3–4 months) and for 2–3 months before a car loan.
