What it means
FICO updates its models periodically to reflect changes in how people borrow and what the data shows about repayment. The version known as FICO Score 8 was an enhancement over earlier models and became the most commonly used base score among lenders.
Newer versions exist, but older ones often stay in use for years because lenders have built their systems and rules around them. One notable feature is its sensitivity to credit utilisation (the share of available credit being used).
It looks closely at how much of the limit is used on individual cards as well as overall. A borrower who maxes out one card can see a lower score even if their total utilisation across all cards looks acceptable.
Another feature is how it treats collection accounts. Earlier versions counted every collection, while this version ignores collections where the original balance was very small, such as under $100.
Late payments, though, still do considerable harm, and the more recent and severe they are, the greater the damage. The model is built on the same broad factors as other FICO Scores: payment history, amounts owed, length of history, new credit and credit mix.
What differs is how those factors are weighted and how particular events are interpreted. Mortgage lenders in the United States have historically used older FICO versions for conforming loans, so a consumer's score for a mortgage may differ from the version used by a card issuer.
For a non-specialist, the practical lesson is that the score you see depends on the version being used. When a lender says they use FICO 08, they mean this specific model, and tips for improving that score, such as lowering card balances, apply most clearly to it.
Lenders often pair the score with other checks, such as income verification and debt-to-income limits. A high score does not guarantee approval, and a modest score does not always lead to a decline.
The score is one piece of evidence in a wider assessment of affordability.
In practice
Real-world examples.
Example
A retail bank uses FICO 08 to pre-screen applicants for a rewards card. An applicant with one nearly maxed card is offered a lower limit than a similar applicant with balances spread evenly.
Example
A consumer has a $60 unpaid gym fee that went to collections. Because the original balance was below the small-collection threshold, the account does not reduce the FICO 08 score, though it may still appear on the credit report.
Example
A borrower preparing for a car loan pays his cards down to under 10% of each limit. He checks his score a month later and sees an increase, because the model rewards low balances on each individual card.
Formula
Calculation
The model's formula is proprietary, but its emphasis on per-card utilisation can be shown:
Card utilisation = Card balance / Card limit
A borrower has a $5,000 limit on card A with a $4,800 balance, and a $15,000 limit on card B with a $200 balance. Card A utilisation is $4,800 / $5,000 = 96%, and card B utilisation is $200 / $15,000 = 1.3%. Overall utilisation is ($4,800 + $200) / ($5,000 + $15,000) = $5,000 / $20,000 = 25%, which looks moderate, yet the 96% on one card can still weigh on the score.Case study
Seen in the real world.
Oakhaven Credit Union is an illustrative, fictional lender that used FICO 08 for its unsecured personal loan decisions. The risk manager noticed that members with one heavily used card were being declined even when their total debt was low.
She reviewed a sample of the declined applications and confirmed that high single-card utilisation was driving the scores down. The credit union began to include a short note in its decline letters, advising members to spread balances or pay down the highest card first.
In this illustrative story many of those members reapplied within a few months with improved scores, and approval rates rose without any loosening of the credit policy. The risk manager valued the model because its behaviour was predictable and explainable to members.
Watch out
Common mistakes.
- Assuming every lender uses FICO 08, when mortgage lenders and some other issuers use different versions.
- Focusing only on total utilisation and ignoring a single card that is close to its limit.
- Thinking small collections can never matter, when they may still be seen by lenders who review the full report.
Questions
People also ask.
What does the 08 stand for?
It refers to the version, FICO Score 8, which was introduced in the late 2000s.
Is FICO 08 better than newer versions?
Not necessarily; newer versions use more data and treat some items differently, but lenders move slowly and many still use this one.
Can I see my FICO 08 score?
Yes, many banks and card issuers share a FICO Score with customers, but check which version it is, since it may not be this one.
