You check a free credit app and it says 740. You apply for a mortgage and the lender pulls your credit and says 690. Same person, same month, 50-point gap. How?
It's not a mistake. You're looking at two different scoring models. Here's why that matters and which one actually counts.
Two different score models
There isn't one single "credit score." Your score is generated by a scoring model applied to the data in your credit file. The two big ones:
- FICO — the original, created in 1989. Used by 90% of top lenders for lending decisions, including most mortgages, auto loans, and credit cards.
- VantageScore — created in 2006 by the three credit bureaus themselves (Equifax, Experian, TransUnion) as a competitor to FICO. Commonly shown in free credit-monitoring apps and bank dashboards.
They use the same underlying credit report data, but they weigh it differently and have different rules. That's why the same file can produce two different numbers.
Key differences
| Feature | FICO | VantageScore |
|---|---|---|
| Used by most lenders | Yes (90%+) | Less often |
| Requires credit history | 6+ months | 1 month |
| Counts paid collections | Still hurts (newer models less) | Ignored |
| Low utilization | Big positive | Big positive |
| Trended data (over time) | Limited | Heavy focus |
Why VantageScore usually looks higher
Free apps tend to show VantageScore because it's cheaper for them to provide and it's more forgiving — it ignores paid collections, it scores with less history, and it can reward trended data (your trajectory over time) more generously. So people often see a higher, friendlier number on their bank app than what a lender sees when they pull FICO.
The score that decides your loan approval and interest rate is almost always FICO — not the number in your free app.
There's also more than one FICO
To make it more confusing, there isn't just one FICO score either. FICO has many versions — FICO 8, FICO 9, FICO 10, plus industry-specific scores like FICO Auto Score and FICO Bankcard Score. Different lenders use different versions, and they can each show a slightly different number for the same file.
For mortgages specifically, most lenders still use older FICO models (FICO 2, 5, 4 — one per bureau) required by Fannie Mae and Freddie Mac. So the mortgage score you see at application can differ from a FICO 8 you'd see elsewhere.
What it means for you
- Don't obsess over the free-app number. It's a useful trend indicator, not the number a lender will see. Use it to track direction, not as gospel.
- Focus on the inputs, not the score. All models reward the same fundamentals: on-time payments, low utilization, long history, few inquiries. Nail those and every model rises together.
- Before a big application, check your real scores. If you're applying for a mortgage, ask the lender which FICO model they'll pull, or get your 3-bureau FICO scores through a paid service that shows them.
- Build for all models at once by never missing a payment and keeping utilization low — that helps you everywhere regardless of the model.
