This co-report, written by John Ulzheimer, is a joint collaboration between Bloom and VantageScore as part of a new series examining credit scoring models and alternative data. The views expressed in this article are the author's own.

The most commonly used credit scoring models in the United States are built by two companies. The first is Fair Isaac or “FICO.” FICO’s credit bureau risk scores have been commercially available from all three of the major credit reporting companies since 1991, and the company has been in existence since 1956. The second is VantageScore Solutions. VantageScore’s credit bureau risk scores have been commercially available from all three of the major credit reporting companies since 2006, the same year the company was formed.

Because FICO has been around for so long they have built and subsequently redeveloped many generations of their scoring models over the span of some three decades. VantageScore has built four generations of their scoring models in the past 13 years. FICO’s most current credit score generation is commonly referred to as FICO 9. VantageScore’s most current credit score generation is referred to as VantageScore Credit Score 4.0, or VS4.

There are a number of similarities between the two commonly used scoring models. But it’s the differences that make them unique. The two scoring platforms are designed and developed by two different companies, so there are natural differences between FICO 9 and VantageScore 4.0.

Similarities Between FICO 9 and VS4

300 to 850 Score Range – The score range or “scale” of both FICO 9 and VS4 is 300 to 850. This identical scaling isn’t unique to the two company’s most current models. FICO’s credit scores have always had 300 to 850 as their range. VantageScore versions 1.0 and 2.0 had a score range of 501 to 990. VantageScore 3.0 was the first of their models to have a 300 to 850 score range.

Design Objective – Every credit scoring model has a performance definition, a design objective that is the reason it is being built. Much like a hammer is designed to drive and remove nails, credit scores too have their specific purpose.

The design objective of both FICO and VantageScore’s credit scores is to predict the likelihood that a consumer will go 90 days past due or worse in the 24 months after the score is calculated.

The various models produced by both companies weight different factors differently and have different model architectures in order for them to be optimally predictive and inclusive within the timeframe that they will likely be used.

The VantageScore 4.0 model was built using a refreshed data set from the years 2014-2016, to take into account the latest credit products and trends in consumer behavior. Development was based on anonymized consumer credit files from all three credit bureaus.

The model weights recent credit activity such as credit line management higher than other more traditional factors like age and depth of credit use. This actually helps those that are new to credit like GenZers and Millennials who aren’t active users of credit get a more accurate credit score.

Tri-Bureau Availability – There are only two scoring platforms (FICO and VantageScore) available from each of the three major credit reporting companies (CRC); Equifax, Experian and TransUnion.

Financial services companies want the flexibility to procure credit reports from any of the three CRCs. The ability for users to get either a FICO score or a VantageScore score from any of the CRCs gives them that flexibility.

VantageScore’s use by lenders has been growing significantly. Global management consulting firm Oliver Wyman studied usage of VantageScore credit scores in the 12-month period between July 1, 2017 and June 30, 2018 (consistent with its similar study one year ago) and found that nearly 10.5 billion credit scores were used by over 2,800 unique users. This represents a 20 percent increase in the number of scores used versus last year’s study. While the consulting firm found use of VantageScore across the consumer credit landscape, it found that among financial institutions, credit card issuers were the largest users of VantageScore credit scores and they accounted for approximately 4.4 billion scores used overall.

Differences Between FICO 9 and VS4

There are many nuanced differences between the two models. Here are a few of interest:

Inquiry Treatment – Both FICO 9 and VS4 will consider inquiries when calculating a credit score. But, they do not consider them the same way. For example, mortgage, auto and student loan inquiries are ignored by FICO 9, and previous FICO scores, if they are less than 30 days old. After they are older than 30 days, if they occurred within 45 days of each other then those multiple inquiries are treated by the scoring model as a single inquiry. VS4, as with previous versions of VantageScore, will treat all inquiries that are within 14 days of each other as a single inquiry.

The reason that the models “dedupe” inquiries is to encourage consumers to shop around for the best rates and terms for loans.

It’s worth noting that once an inquiry of any type becomes greater than one year old, neither scoring system will consider them in the scoring process.

The Minimum Scoring Criteria – In order for a FICO or VantageScore credit score to be calculated the consumer’s credit report must meet certain minimum standards. If the following standards are not met then the consumer’s credit report has failed the minimum scoring criteria and will not be scored.

FICO 9, and Prior Versions – The consumer must have at least one undisputed tradeline (a.k.a. credit account) that is at least six months old, and the consumer must have at least one undisputed tradeline that has been updated in the past six months. Finally, the consumer cannot have any sort of deceased indicator on their credit report.

NOTE: One account can satisfy the above criteria. For example, if the consumer has a Wells Fargo mortgage loan on their credit report that is three years old and was updated last month, the consumer’s credit report will qualify for a FICO score.

VantageScore 4.0, and Prior Versions – Consumers can be scored who have tradelines that are less than six months old or who haven’t had an update/reporting on their credit files in the past six months but have had updates that are more than six months old. This enables the model to score approximately 40 million more consumers than conventional models.

This is an important differentiator for VantageScore. The VantageScore model represents a market-based solution to a broader economic challenge: making consumer lending market more accessible to creditworthy consumers who are otherwise unscoreable while creating a corresponding opportunity for lenders.

The VantageScore model can better distinguish between consumers with a clear track record of unfavorable credit behaviors from those who are simply starting to develop, or re-develop, credit histories. Individuals in these groups typically include:

Young adults just starting their careers or who are new to credit

Recently divorced or widowed individuals with little or no credit in their own name

Newly arrived immigrants

A breakdown by ethnicity is as follows:



2018 Unscoreables - All Scores

Total: 40 million

40 million Black and Hispanic: 12.2 million

12.2 million Asian/Pacific-Islander: 1.6 million

1.6 million White: 25.7 million

2018 Unscoreables - Scores 620+

Total: 10.06 million

10.06 million Black and Hispanic: 2.4 million

2.4 million Asian/Pacific-Islander: <1 million

<1 million White: 7 million

Demonstrating this predictive performance improvement, there is nearly an identical alignment of default rates between those with limited credit histories and those who have conventional credit behaviors in the first year of a new account.

Consideration of Trended Data – Several years ago the credit reporting companies began maintaining a historical monthly record of the balances and actual payment amounts on your loans and credit cards. This is called trended data and it allows for differentiation between someone who pays their credit cards in full each month versus someone who pays less than their full balance and revolves some amount to the next month.

FICO’s scores do not consider this trended or historical payment data. VantageScore 4.0 does consider trended data. Prior versions of VantageScore do not consider trended data.

The predictive power of trended credit data is particularly evident among higher scoring consumers. That’s because very high risk consumers commonly have easily distinguishable credit behaviors that exhibit higher risk like missed payments and collection accounts.

One way lenders determine the predictive “lift” one model has versus another is to examine how many more loan applications may be approved while holding a desired default rate tolerance steady. According to VantageScore, a lender that holds its risk appetite for default rate constant at 1.5%, VantageScore 4.0 allows an incremental 5% of the prospects to be approved compared to a weaker generic static credit score.
