If you've ever checked your credit score in two different apps and seen two different numbers, you're not imagining it. FICO and VantageScore are two separate scoring models, built by different companies, using slightly different formulas — and both are widely used.
What each one is
- FICO Score — created by the Fair Isaac Corporation, the older and historically more widely used model, especially for mortgage lending.
- VantageScore — created jointly by the three credit bureaus (Equifax, Experian, TransUnion) as a competing model, now common in many free credit-monitoring apps.
Key differences
| FICO Score | VantageScore | |
|---|---|---|
| Score range | 300-850 | 300-850 (current version) |
| Minimum history needed | About 6 months | As little as 1 month, with 1 reported account |
| Weighting | Payment history weighted most heavily | Similar factors, somewhat different weighting |
| Common use | Most widely used by mortgage lenders | Common in free credit-monitoring apps |
Why your score varies between apps
Which one actually matters for your application?
It depends on the lender. Mortgage lenders very commonly use specific older versions of FICO scores. Credit card issuers and auto lenders may use either model, sometimes a specific industry-tailored version of FICO. There's no single 'real' score — what matters is understanding the factors that drive both models in the same direction, which are largely the same: payment history, utilization, account age, credit mix, and new credit.
Should you worry about the difference?
For everyday purposes — tracking your progress, deciding whether you're likely to qualify for a given product — the exact model matters far less than the trend. If your VantageScore is climbing because you're paying down balances and paying on time, your FICO Score is almost certainly moving in the same direction, even if the exact numbers differ slightly.
- Use whichever free score your bank or card issuer provides to track your general trend over time.
- Don't panic over small differences between two apps — focus on the underlying habits, not the exact number.
- If you're about to apply for a mortgage specifically, ask your lender which score version they'll actually pull.
