FICO vs. VantageScore: What's the Difference and Which Matters?
FICO and VantageScore use different formulas and different scales. Here's which one lenders actually use and why your apps show different numbers.
The Two Main Credit Scores
Every "credit score" you see comes from one of two formulas: FICO or VantageScore. They use the same data (your three credit reports) but weigh it differently and can produce scores that differ by 30–80 points.
Which One Do Lenders Use?
FICO is used in over 90% of lending decisions. If you're applying for a mortgage, auto loan, or major credit card, the underwriter is pulling a FICO score — usually a specific industry version like:
- FICO Score 2, 4, or 5 for mortgages
- FICO Auto Score 8 or 9 for auto loans
- FICO Bankcard Score 8 for credit cards
VantageScore is what most free apps (Credit Karma, Chase Credit Journey, NerdWallet) display. It's the same data, just a different formula.
Why the Numbers Differ
| Factor | FICO Weight | VantageScore Weight |
|---|---|---|
| Payment History | 35% | 40% |
| Credit Utilization | 30% | 20% |
| Length of History | 15% | 21% |
| Credit Mix | 10% | 11% |
| New Credit | 10% | 5% |
VantageScore also includes rent and utility payments when reported, and penalizes high utilization less aggressively.
Why Your Credit Karma Score Doesn't Match Your Lender's
You'll often see a 720 on Credit Karma and a 680 from a mortgage lender. Three reasons:
- Different formula (VantageScore 3.0 vs. FICO Score 5)
- Different bureau (Credit Karma uses TransUnion + Equifax; mortgage uses all three middle scores)
- Different age of data
What to Watch
For the most relevant FICO scores:
- myFICO.com — paid but shows all 28 FICO versions
- Experian.com — free FICO 8
- Your bank's app — many now display FICO 8 for free
Bottom Line
Track VantageScore in free apps to watch movement, but assume your real "lender score" is 30–50 points lower than what Credit Karma shows. Plan accordingly when applying for major loans.
