FICO vs. VantageScore: the real differences that change your number

FICO says 90% of top lenders use FICO Scores. VantageScore says its 4.0 model can “accurately assess approximately 33 million more consumers” than conventional models. Both numbers come from the companies themselves, and both are partly sales pitches. What neither tells you is why a FICO Score and a VantageScore built from the same credit report can land far apart.

Both read the same data and do different math with it. A few specific items on your report get treated very differently by each formula, and the one your lender uses decides which treatment you get.

Who makes each score

FICO is the older brand: Fair Isaac sells its scores to lenders through the three bureaus, and it maintains many versions at once: FICO 8, FICO 9, FICO 10 and 10T, the older mortgage versions, and industry-specific auto and bankcard scores. myFICO calls FICO 8 “the most widely used version.”

VantageScore launched in March 2006 as a joint product of Equifax, Experian and TransUnion. Its first two versions used a 501 to 990 scale. VantageScore 3.0 moved to 300 to 850 in 2013, and VantageScore 4.0 has been in production since 2017, according to the company. When a free app shows you a score, it’s often VantageScore 3.0.

Neither company collects data about you. Both send their formulas to the bureaus, which run them against whatever is on your file at that moment.

Side by side: where they actually differ

The scale is identical, so the differences hide in how each model treats specific items. This table compares the versions you’re most likely to meet.

Two rows deserve a closer look.

Thin files. FICO’s minimum requirements are spelled out on myFICO: at least one account opened six months or more, at least one account reported to a bureau in the past six months, and no deceased indicator. VantageScore 4.0 instead uses machine learning on files with sparse histories, so if you’re new to credit you may be able to get a VantageScore before you qualify for any FICO Score. VantageScore says this approach scores roughly 33 million people that other models can’t, a vendor figure worth reading as a claim rather than a measured fact.

Trended data. A traditional score sees one snapshot: the balance each card reported most recently. VantageScore 4.0 and FICO 10T look at the pattern over time, so someone paying balances down can look different from someone running them up, even if this month’s balances match. Our page on FICO score versions works through that example with numbers.

A worked example: the paid collection

The two families split most visibly on collections, and one paid account shows it.

Say a $900 final bill from an old cell phone contract went to a collection agency two years ago, and you paid it in full last spring. Your report now shows a collection account with a $0 balance, marked paid.

• FICO 8 and the classic mortgage FICO Scores still see a collection account. Paying it changed the balance, not the fact that it went to collections, so it keeps counting until it ages off the report.
• FICO 9 and FICO 10 treat a paid third-party collection as having no negative impact, according to myFICO.
• VantageScore 3.0 and 4.0 ignore paid collections.

Same report, same day, and one family of scores counts the account while the other doesn’t. Neither FICO nor VantageScore publishes how many points that’s worth, so anyone quoting you a precise figure is guessing. (Medical collections follow separate bureau policies; see medical debt on credit reports.)

If your app shows VantageScore 3.0 and you have a paid non-medical collection, your app score may run higher than what a lender pulling FICO 8 will see.

Which one is more accurate?

Each company says its newest model wins. VantageScore claims 4.0 identifies “up to 13% more defaults” than Classic FICO across mortgage loans. FICO says multiple independent analyses found FICO 10T to be the most predictive score available to mortgage lenders, and that more than 70 mortgage lenders had signed up for its 10T access program by July 2026. Both claims come from the vendors, and there’s no neutral referee whose findings you can check.

For you, accuracy is the wrong question. The score that matters is the one your lender pulls, because that’s the number your approval and your interest rate come from.

Which score each kind of lender pulls

Card issuers, auto lenders and mortgage lenders each lean on different scores.

• Credit cards. myFICO says card issuers commonly use FICO Bankcard Scores or FICO 8 or 9.
• Auto loans. Most auto lenders use FICO Auto Scores, which run on a 250 to 900 scale.
• Personal, student and retail loans. FICO 8 is the common choice.
• Conventional mortgages. Since September 9, 2026, every lender approved by Fannie Mae and Freddie Mac can choose either Classic FICO or VantageScore 4.0, with one catch: all borrowers on a loan must be scored with the same model, according to FHFA.
• FHA mortgages. HUD’s Mortgagee Letter 2026-11 adds VantageScore 4.0 and FICO 10T alongside Classic FICO for case numbers assigned on or after January 1, 2027.

The mortgage details, including how lenders pick one score from three, are in the credit scores mortgage lenders actually pull.

What to do with this

You can’t choose the model a lender uses, but you can stop being surprised by it.

• Read the fine print under every score you see and note the model and bureau. “VantageScore 3.0, TransUnion” and “FICO 8, Experian” are different measurements.
• Before a big application, ask the lender which score it uses. Some will tell you, and the answer changes how much weight to give your app score.
• If you have a paid collection, expect FICO 8 and the classic mortgage scores to keep counting it. Our guide to why your free score doesn’t match your lender’s covers how to see something closer to the lender’s view.
• If you’re new to credit and have a VantageScore but no FICO Score yet, give your oldest account time to pass six months. That’s FICO’s rule, and it’s one of the few in scoring that’s published down to the month.
• Check the reports themselves. Both models are only as good as the data, and you can get all three reports free every week at AnnualCreditReport.com. The glossary entry on VantageScore covers the terms you’ll see along the way.
