FICO and VantageScore both use the same 300 to 850 range and the same credit report data, but they weigh factors differently, so they produce different numbers. The practical difference: FICO is what the vast majority of lenders use, especially for mortgages, while VantageScore is what you usually see free on apps like Credit Karma. Neither is more accurate; they are just different models. For real decisions like a mortgage, FICO is the one that counts. Here is what you actually need to know.
Key Takeaways
- FICO is used by most lenders, especially for mortgages; VantageScore is common in free apps.
- Both use the 300 to 850 range and the same report data, but weigh factors differently.
- Your two scores often differ by 20 to 50 points, which is normal and not a red flag.
- Improving the same habits (on-time payments, low utilization) raises both scores.
What Are the Key Differences?
| FICO Score | VantageScore | |
|---|---|---|
| Used by lenders | Vast majority of top lenders | Growing, but still a minority |
| Score range | 300-850 | 300-850 |
| Data needed to score | 1 account open 6+ months, recent activity | As little as 1 to 2 months of history |
| Free access | Experian, many bank and card dashboards | Credit Karma, Credit Sesame |
| Versions | FICO 8, 9, 10, 10T (mortgage) | VantageScore 3.0, 4.0 |
| Rental history | Not in most versions | Included in 4.0 |
Why Do Your VantageScore and FICO Score Differ?
The two often differ by 20 to 50 points, sometimes more, for a few reasons:
- Different factor weights. FICO sets payment history at 35%, while VantageScore treats payment history as even more influential.
- Different treatment of collections. FICO 9 ignores paid collections, FICO 8 still counts them, and VantageScore 4.0 ignores collections under $250.
- Different data freshness rules for how recent your activity must be to score.
- Different handling of rent and utility history, which VantageScore 4.0 can include.
Neither model is more accurate. They are different formulas producing different outputs from the same underlying data. See our guide on how your credit score is calculated.
Which Score Should You Focus On?
For monitoring trends: any score works, because changes in one generally reflect changes in all. If your Credit Karma (VantageScore) rose 30 points, your FICO scores likely improved too, even if by a different amount.
For a mortgage: FICO is what matters. Most conventional lenders have long used older versions: FICO Score 5 (Equifax), FICO Score 4 (TransUnion), and FICO Score 2 (Experian), which are older than the FICO 8 you usually see for free. In April 2026, the FHFA and HUD approved VantageScore 4.0 and FICO 10T alongside Classic FICO for conventional loans backed by Fannie Mae and Freddie Mac, but the rollout is staged: VantageScore 4.0 is available at approved lenders on a limited basis, with FICO 10T historical data expected in summer 2026 and broader adoption continuing into 2027. Many lenders still use Classic FICO during the transition.
Where Can You See Your FICO Score for Free?
Experian’s free account shows your FICO Score 8 from Experian, and many cards (Discover, Citi, Bank of America) show a free FICO Score 8 in their apps. For the exact mortgage versions (FICO 2, 4, and 5), myFICO.com charges a fee but shows what mortgage lenders will actually see. See our guide on the best free credit monitoring.
Should You Panic About Score Discrepancies?
No. Seeing a 720 on Credit Karma and a 680 on myFICO is disorienting but not a problem. The credit behavior driving both is the same, so improving your payment history and lowering utilization moves both up. Focus on building good credit habits rather than optimizing for one specific model.
FAQ
Is FICO or VantageScore more accurate?
Neither. They are different models scoring the same data with different weights. FICO simply matters more in practice because most lenders, especially mortgage lenders, use it.
Why is my Credit Karma score higher than my FICO score?
Credit Karma shows a VantageScore, which weighs factors differently and can read higher or lower than your FICO. Differences of 20 to 50 points are normal and not a sign of an error.
Which credit score do mortgage lenders use?
Conventional lenders have used Classic FICO (versions 2, 4, and 5). As of April 2026, VantageScore 4.0 and FICO 10T are also approved for Fannie and Freddie loans, but adoption is rolling out gradually through 2026 and 2027.
Should I pay for my FICO score?
Usually not. Free FICO 8 access through Experian or your card issuer is enough for tracking. Pay for myFICO only if you want the exact mortgage-version scores before applying for a home loan.
Bottom Line
FICO and VantageScore use the same range and data but different formulas, so they differ by design; FICO is the one lenders actually use, especially for mortgages. Track either score for trends, check your free FICO 8 before big applications, and remember that the same good habits raise both.
