Checking your credit score used to mean one number, probably FICO, probably outdated. In 2026, most consumers have at least six active scores across two models. VantageScore 4.0 and FICO 10 are the newest generation of each, and they disagree with one another more often than older versions did. If a lender pulled your file tomorrow, which score would they see, and why might those two numbers be 20 points apart?
Here is the honest, plain-English breakdown.
Why Two Score Models Exist
FICO is made by Fair Isaac Corporation and has dominated lending since 1989. VantageScore launched in 2006 as a joint venture among Equifax, Experian, and TransUnion, the three credit bureaus that supply the raw data. Both models predict the likelihood you will fall 90 days behind on a payment in the next 24 months. They just get there different ways.
Lenders choose which model they pull, and many pull more than one. Mortgage lenders mostly use older FICO versions (FICO 2, 4, and 5). Credit card issuers increasingly pull FICO 8, FICO 9, FICO 10, or VantageScore 3.0 and 4.0. Auto lenders often use FICO Auto Score. The point is that "my credit score" is rarely a single number in the real underwriting world.
Monitoring both scores is not optional if you want a full picture. Services like Creditship and Dovly let you watch both model families in one dashboard.
The Shared Foundation
Before the differences, it helps to know what both models agree on.
- Both use a 300 to 850 range.
- Payment history is the single largest factor in both.
- Credit utilization, credit age, credit mix, and new credit are ingredients in both.
- Both pull from the same three bureau files. A lender who pulls FICO 10 from Experian and VantageScore 4.0 from Experian is looking at the same underlying trade lines.
Key Difference 1: Trended Credit Data
FICO 10 has a companion version called FICO 10 T. The T stands for trended, meaning the model looks at 24 months of balance history, not just the latest snapshot. A borrower who pays $500 on a $3,000 balance every month looks better than someone who makes only the minimum. FICO 10 by itself does not use trended data; FICO 10 T does.
VantageScore 4.0 uses trended credit data by default. Every application of the model looks at the 24-month arc. That is why a consumer who has been paying down balances consistently often sees their VantageScore 4.0 outpace a FICO 8 or even a FICO 10 score.
Bottom line: if you are steadily reducing balances, VantageScore 4.0 tends to reward you faster.
Key Difference 2: Medical Collections Treatment
Medical collections have been stripped out of most scoring models in recent years. VantageScore 4.0 ignores paid medical collections entirely and weights unpaid ones lightly. FICO 10 follows a similar approach, ignoring paid medical collections and sharply reducing the weight of unpaid ones. If medical debt was dragging your file, both new models should help.
Older models (FICO 8, VantageScore 3.0) still factor medical collections more heavily, which is one reason two scores pulled on the same day can vary by 30 points or more.
Key Difference 3: Rent, Utility, and Telecom Data
VantageScore 4.0 readily accepts rent, utility, and telecom payments when those are reported to the bureaus. That matters for thin-file consumers, including young adults, newcomers to the US, and anyone rebuilding after bankruptcy. Reporting 12 months of on-time rent through a service you can read about in our Boom rent reporting review can lift a VantageScore 4.0 by 20 to 40 points.
FICO 10 is more conservative. It considers alternative data only through FICO's UltraFICO product, which requires separately granting bank-account access. Most lenders pulling FICO 10 today do not look at your rent history.
Key Difference 4: How the Models Handle Thin Files
VantageScore 4.0 can score a consumer who has only one tradeline that is as little as one month old. FICO 10 requires at least six months of history and at least one account reported in the last six months. That gap makes VantageScore 4.0 friendlier to brand-new borrowers. A first-time user of the Self Visa® Credit Card may see a VantageScore weeks before a FICO score appears.
Key Difference 5: Penalty for Hard Inquiries
Hard inquiries drop both scores slightly, but VantageScore 4.0 uses a broader deduplication window. Multiple inquiries for the same loan type (say, auto) within 14 days count as one. FICO 10 uses a 45-day window for auto, mortgage, and student loans. That 45-day window is more forgiving for rate shopping, but outside those three categories FICO also counts each inquiry individually.
Key Difference 6: Credit Mix and Account Variety
Both models like a mix of installment and revolving accounts. FICO 10 weighs this category slightly heavier than VantageScore 4.0. A borrower who carries only credit cards may see a lower FICO 10 than VantageScore 4.0, all else equal.
Which Score Should You Focus On?
Practically speaking, if you are applying for a mortgage this year, the lender will pull older FICO versions (2, 4, 5). If you are applying for a credit card or an auto loan, you are more likely to be evaluated against FICO 10, FICO 8, or VantageScore 4.0. The right move is to monitor both families and not fixate on a single number.
Our guide on how to build credit from scratch covers the habits that lift both models together, because in the end the two scores reward the same fundamentals.
Bottom Line
VantageScore 4.0 is more generous to thin-file and recovering borrowers thanks to trended data and alternative-data acceptance. FICO 10 is stricter but remains the dominant choice among credit-card and auto lenders. Track both through a monitoring service, keep your utilization low, pay on time, and add one positive tradeline every six months. The rest usually takes care of itself.
Frequently Asked Questions
Do lenders actually use VantageScore 4.0?
Adoption is steadily rising, especially among fintech lenders, credit-card issuers, and some auto lenders. Major mortgage lenders are beginning to pilot VantageScore 4.0 alongside older FICO models in 2026, with broader adoption expected as regulators approve it for conforming loans.
Why is my VantageScore higher than my FICO?
Three common reasons: trended data rewarding paydowns, alternative-data inclusion like rent, and more forgiving treatment of short credit history. If you are a thin-file consumer, VantageScore almost always runs higher than FICO.
Is FICO 10 T the same as FICO 10?
No. FICO 10 is the standard version. FICO 10 T adds trended-data analysis. Lenders can choose which to pull, and different industries are adopting each at different speeds.
Can I raise both scores at the same time?
Yes. Pay every bill on time, keep revolving utilization under 10 percent, add one new tradeline at a time, and avoid unnecessary hard inquiries. These behaviors raise both VantageScore 4.0 and FICO 10 because payment history and utilization are the two largest factors in both models.
