FICOvs.VantageScore

If you’ve ever seen two different credit scores for yourself and wondered which one is “real,” here’s the short answer: both are. The U.S. has two dominant scoring companies (FICO and VantageScore), and your bank, your credit card app, and a mortgage lender might each show you a different number from a different model.

Neither is fake. They’re just built by different companies, from the same underlying credit reports, with slightly different recipes.

90% of top U.S. lenders use a FICO score. But the free score in your app is often a VantageScore, which is why they can disagree.

The two models, side by side

FICO (from Fair Isaac Corporation) has been around since 1989 and is the score most lenders pull ² . FICO Score 8 is the version most widely used ³ , with FICO 9, 10, and 10T also in the market.

VantageScore is a joint venture of the three credit bureaus (Equifax, Experian, and TransUnion), created in 2006. Its 4.0 model is the one in wide use today (5.0 arrived in 2025) ⁶ , and it powers a lot of the free scores you see in banking apps.

Both run on the same 300–850 scale, and both are built to predict the same thing: how likely you are to repay.

How they weigh your file

FICO publishes exact percentage weights ¹ ; VantageScore groups the same behaviors into influence tiers rather than fixed numbers ⁵ . Two ways of describing the same thing:

The headline, either way, is the same: pay on time, keep balances low, and let your accounts age. (We break the FICO factors down further in how credit scores work.)

Where they differ in practice

The models diverge in a few specifics worth knowing:

• Thin files. VantageScore can often score a newer file (as little as one month of history), while FICO generally needs about six months and a recently reported account. If you’re brand new to credit, you may have a VantageScore before a FICO.
• Rate shopping. Both bunch multiple inquiries for the same loan into one when you shop in a window: VantageScore uses about 14 days, while newer FICO models stretch it to as much as 45.
• Collections. FICO 9 stopped counting paid collection accounts and softened the blow of unpaid medical collections ⁴ ; VantageScore’s recent models treat paid and medical collections gently too.

You don’t have one credit score. You have several, and FICO and VantageScore won’t always agree on the number.

Which one will a lender use?

It depends on the loan, and the lender chooses, not you:

Because the model isn’t up to you, there’s no point trying to “optimize for VantageScore” or game one version. The fundamentals move every model in the same direction.

So why are my two numbers different?

A few reasons stack up, and all of them are normal: the two companies use different formulas, lenders pull different versions, each bureau may hold slightly different data, and the scores are calculated on different days. The CFPB puts it plainly: you have many scores, and they won’t all match ⁷ .

Treat any single score as a snapshot, not the truth. Watch the trend, not the one decimal point of difference between apps.
