FICO 8 vs FICO 9: What's Different and Which Lenders Use What
FICO 8 is the most widely used credit scoring model, in use since 2009. FICO 9 launched in 2014 with three meaningful changes that benefit most consumers: paid collections are ignored, medical collections are weighted less, and rent payments can be counted. Despite being a decade old, FICO 9 adoption has been slow — most lenders still use FICO 8 (or industry-specific FICO scores). Here's the side-by-side and what to expect from each.
The Three Big FICO 9 Changes
1. Paid collections are ignored
In FICO 8, a collection account hurt your score even after you paid it off — the mark stayed on your report and counted against you for 7 years.
In FICO 9, paid collections are ignored entirely. As soon as a collection is marked paid, it stops affecting your score. The mark still appears on your credit report (until 7 years pass), but it doesn't move the number.
For someone with paid collections, the score difference between FICO 8 and FICO 9 can be 30–60 points.
2. Medical collections are weighted less
Medical debt is often the result of insurance disputes, billing errors, or genuine emergencies — not financial irresponsibility. FICO 9 acknowledges this by treating medical collections as less severe than other collections.
Combined with the 2023–2024 industry reforms (no reporting of medical collections under $500, paid medical collections removed entirely), medical debt has become much less destructive to a credit score in 2026 than it was a decade ago.
3. Rent payments can be counted (when reported)
FICO 9 includes rent payment history when it's reported by the landlord or via a third-party rent-reporting service. FICO 8 ignores rent. For renters with thin or rebuilding credit, this can add a positive tradeline that wasn't possible before.
Which Lenders Use Which Model
Most lenders use FICO 8 by default. Mortgage lenders use older industry-specific FICO models (FICO 2, 4, and 5) due to GSE requirements at Fannie Mae and Freddie Mac — not FICO 8 OR FICO 9. Auto lenders use the FICO Auto Score 8 or 9. Credit card issuers use the FICO Bankcard Score 8 or 9.
FICO 9 adoption highlights:
- Mortgage: Mostly NOT using FICO 9. Conventional loans rely on FICO 2, 4, 5. The FHFA approved FICO 10T and VantageScore 4.0 for conventional mortgages, with rollout still in progress.
- Auto loans: Some lenders use FICO Auto 9, but FICO Auto 8 is still dominant.
- Credit cards: Mixed; many issuers use FICO Bankcard 8.
- Personal loans: Mixed; newer fintech lenders are more likely to use FICO 9 or VantageScore 4.0.
What This Means for You
- If you have paid collections: Your FICO 9 score is meaningfully higher than your FICO 8. When applying for credit, ask which model the lender uses.
- If you have medical debt: The 2026 environment is friendlier than the 2010s. New rules + FICO 9 + VantageScore 4.0 all reduce medical-debt impact.
- If you're a renter: Get your rent reported. Self-reporting via apps like Self.Inc Rent & Utility Reporting (free) or services like Piñata adds positive payment history visible to FICO 9, FICO 10T, and VantageScore 4.0.
- If you're rebuilding credit: Add positive tradelines. The Self.Inc Credit Builder Account, the Self Visa® Credit Card, the Current Build Card (no credit check), and the Kikoff Secured Credit Card all build the same payment history that FICO 8 and FICO 9 reward equally.
FICO 10 and VantageScore 4.0
FICO 10 (and FICO 10T — the trended version) launched in 2020 and adds the use of "trended data" (24-month payment patterns) for more accurate risk prediction. VantageScore 4.0 (2017) is the most consumer-friendly mainstream model and is increasingly used by free monitoring services. Both ignore paid collections like FICO 9.
Lender adoption of FICO 10 is even slower than FICO 9 — expect another 5–10 years before FICO 10 is the default in most underwriting.
Frequently Asked Questions
Does FICO 9 use the same factors as FICO 8?
Mostly yes — same five categories (payment history 35%, utilization 30%, credit age 15%, mix 10%, new credit 10%) and roughly the same weighting. The differences are in how specific events (paid collections, medical collections, rent) are scored within those categories.
Which FICO model do mortgage lenders use?
Conventional mortgages backed by Fannie Mae and Freddie Mac use FICO 2, 4, and 5 (older industry-specific models) — not FICO 8 or 9. The FHFA has approved FICO 10T and VantageScore 4.0, with adoption ramping up but still incomplete in 2026.
Why is my FICO 9 score higher than my FICO 8?
Most likely because you have paid collections that FICO 9 ignores but FICO 8 still counts. Medical collections also weigh less in FICO 9. The score gap can be 30–60 points if collections are a major factor in your file.
Where can I see my FICO 9 score?
MyFICO.com sells access to multiple FICO models, including FICO 9. Some banks and credit cards (Citi and others) also display FICO 9 in their cardmember dashboards. Free monitoring services typically show FICO 8, FICO Bankcard, or VantageScore.
