Key Takeaways

• FICO® Score 9, released in 2014, ignores paid third-party collection accounts entirely — a change that can move a score on files where collections are the dominant negative.
• Unpaid medical collections still count under FICO Score 9, but carry less weight than non-medical collections.
• FICO Score 9 is the first base FICO model to factor in rental payment history, when a landlord or rent-reporting service furnishes it to the bureaus.
• The score range is unchanged at 300–850, and the five scoring factors are the same as FICO Score 8.
• Despite being more than a decade old, FICO Score 9 has not displaced FICO Score 8 as the base model most lenders use.

What Is FICO Score 9?

FICO Score 9 is a base consumer credit score released by Fair Isaac Corporation in 2014. It uses the same 300–850 scale and the same five factor categories as FICO Score 8, and predicts the same outcome: 90-day delinquency within 24 months. 

What changed is how the model reads three specific kinds of information — paid collections, medical debt, and rent.

Those three changes are narrow. For a borrower with clean payment history and moderate utilization, FICO 8 and FICO 9 will land in roughly the same place. The gap opens on damaged files, which is exactly where prequalification decisions get difficult.

The Three Changes That Matter

Here’s where FICO Score 9 differs.

Paid collections drop out entirely

Under FICO Score 8, a collection account keeps dragging on a score after it is paid. The account remains on the report for up to seven years and continues to count.

FICO Score 9 stops counting it the moment it reports as paid. The tradeline still appears on the credit report, but it no longer moves the number. On a file where collections are the primary derogatory, the difference between the two models can be substantial.

Medical collections carry less weight

FICO Score 9 separates medical collections from other collections and reduces their impact. Experian's explanation of the model points to FICO's own research: unpaid medical debt is a weaker predictor of future default than other unpaid debt.

The reasoning is straightforward. Medical debt is usually involuntary, frequently the product of a billing or insurance dispute, and often unrelated to how a person manages credit they chose to take on. FICO Score 8 treats a $2,400 emergency room bill in collections the same as a walked-away credit card.

Rent counts, when it's reported

FICO Score 9 is the first base FICO model to consider rental payment history. The catch is furnishing: most landlords do not report to the bureaus. Unless the renter uses a third-party rent-reporting service or rents from a large operator that furnishes data, there is nothing for the model to read.

For thin-file borrowers, this is the difference between a scoreable file and a manual underwrite.

The Regulatory Backdrop Lenders Should Track

Medical debt on credit reports has been contested territory, and the current state of play is not what many lenders assume.

In January 2025, the Consumer Financial Protection Bureau (CFPB) finalized a rule that would have barred consumer reporting agencies from including medical debt in reports furnished to creditors, and barred creditors from considering it. On July 11, 2025, the U.S. District Court for the Eastern District of Texas vacated that rule in Cornerstone Credit Union League v. CFPB, holding that it exceeded the Bureau's authority under the Fair Credit Reporting Act (FCRA). The rule never took effect. The CFPB's own rule page reflects the vacatur.

What does apply:

• Voluntary bureau policies. Equifax, Experian, and TransUnion removed paid medical collections regardless of amount, and medical collections under $500, beginning in 2022–2023. These remain in place and are independent of the vacated rule.
• State law. A number of states have enacted their own restrictions on medical debt reporting. Preemption questions are unsettled, so lenders operating across state lines should get jurisdiction-specific guidance rather than applying one national policy.
• FICO Score 9's treatment, which is a modeling decision by FICO, not a regulatory requirement.

Between the sub-$500 removals and FICO 9's reduced weighting, the practical impact of medical debt on a scored file is smaller today than it was five years ago. It has not disappeared.

Why FICO 9 Adoption Lagged

FICO Score 9 is more favorable to most borrowers than FICO Score 8, which raises an obvious question: why do most lenders still run FICO 8?

Switching scoring models is not a settings change. A lender who moves from FICO 8 to FICO 9 has to:

• Revalidate cutoffs
• Restate portfolio risk against a new distribution
• Update pricing tiers
• Retrain underwriters
• Adjust fair lending testing
• Re-paper vendor agreements

The model has to be measurably better to justify that, and for many portfolios, FICO 9's changes are too narrow to force the issue.

FICO 8 also has more than fifteen years of observed performance behind it. Risk teams weigh that heavily.

FICO 9 in Practice

FICO Score 9 shows up most often in card portfolios, some personal lending, and consumer-facing dashboards. It is not used for conforming mortgage lending — that remains Classic FICO (2, 4, 5), with VantageScore 4.0 now permitted for approved lenders under the FHFA's interim policy.

The operational point for brokers and lenders: Your applicant may have a FICO 9 from a card issuer's dashboard, and your funding source may pull FICO 8 or Classic FICO. If the file has paid collections, those two numbers can diverge enough to change the program the borrower qualifies for.

Pulling the right model early prevents that surprise. A full file soft pull from Soft Pull Solutions returns the same tradeline and collection detail a hard inquiry would, without an inquiry on the consumer's file, and reports can be configured to return the scoring model your lender actually uses. For teams running volume, the same data flows through the credit reporting API into your LOS.

Whichever model you use, permissible purpose and documented consumer consent are required under the FCRA before any pull, and adverse action obligations attach when you decline or offer less favorable terms based on a report. A compliance dashboard that logs consent and generates adverse action letters keeps that defensible.

Stop guessing which score your borrower will actually get. Soft Pull Solutions delivers full credit reports and FICO® Scores through a soft pull — tri-bureau data, no SSN required, no impact on the consumer's credit. Schedule a demo or call (844) 515-1550.

Frequently Asked Questions

Is FICO Score 9 better than FICO Score 8?

For borrowers, usually — it ignores paid collections, softens medical debt, and can count rent. For lenders, "better" depends on whether those changes improve rank-ordering in your portfolio. FICO 8 remains the more widely used base model.

Does FICO Score 9 ignore all collections?

No. It ignores paid third-party collections. Unpaid collections still count, and unpaid medical collections still count at reduced weight.

Will paying off a collection raise my customer's score?

Under FICO Score 9, yes — the account stops counting once it reports paid. Under FICO Score 8, paying it will not remove the impact.

Do mortgage lenders use FICO Score 9?

No. Conforming mortgage lending uses Classic FICO or, for approved lenders, VantageScore 4.0.

Can rent payments help a thin-file borrower under FICO 9?

Only if the rent is furnished to the bureaus by a landlord or rent-reporting service. Most rent is not reported.
