Why Are My FICO and Vantage Scores Different?
Understand why your FICO and Vantage Scores often differ. Get clear insights into credit scoring models and their variations.
It is common for individuals to encounter varying credit scores from different sources, such as banking applications or credit monitoring services. These discrepancies often arise because different scoring models, primarily FICO and VantageScore, are used to evaluate credit data. Understanding the reasons behind these differences can help clarify why your scores may not always align across various platforms.
Understanding FICO and VantageScore
FICO, derived from the Fair Isaac Corporation, is the oldest and most widely adopted credit scoring model used by lenders across the United States. Introduced in 1989, FICO has become a standard in lending decisions, influencing loan approvals and interest rates.
VantageScore was developed collaboratively by the three major credit bureaus—Equifax, Experian, and TransUnion—in 2006 as an alternative to FICO. This model has seen increasing adoption, particularly by free credit monitoring services. Both FICO and VantageScore assess creditworthiness based on information in credit reports, but they use distinct algorithms that interpret and weigh data differently.
Differences in Scoring Methodologies
The core reason for variations between FICO and VantageScore lies in their differing approaches to weighing various credit factors. FICO models typically assign a weight of 35% to payment history, emphasizing timely payments. Amounts owed, or credit utilization, account for 30% of a FICO score. The length of one’s credit history contributes 15%, while new credit and credit mix each account for 10%.
In contrast, VantageScore 3.0 places a higher emphasis on payment history (40%). Depth of credit, including age and types of accounts, is 21%, and credit utilization is 20%. Balances represent 11%, recent credit accounts 5%, and available credit 3%. These different weightings mean specific actions can impact one score more significantly than the other.
Another difference is their minimum data requirements. FICO generally requires a credit report to have at least one account open for six months or more, with activity reported within the past six months. VantageScore can often generate a score with as little as one month of credit history on a single account reported within the last 24 months.
The models also treat certain credit events distinctively. VantageScore 3.0 and 4.0 disregard paid collection accounts and specifically exclude all medical collection data. While newer FICO versions (9 and 10) also ignore paid collections, FICO 8 still considers them.
For rate shopping inquiries, both models group inquiries for the same loan type within a specific timeframe. FICO’s grouping window typically ranges from 14 to 45 days, while VantageScore generally uses a 14-day window. Both FICO and VantageScore generally operate on a 300-850 scale for their most common versions.
Variations in Data and Timing
Even if FICO and VantageScore used identical scoring algorithms, differences in the underlying credit report data could still lead to varying scores. Lenders and creditors often report account activity to the three major credit bureaus—Equifax, Experian, and TransUnion—at different times or may not report to all three. This means a credit report from one bureau might contain different information than another, impacting the score generated from each.
The precise moment a credit score is generated also influences its value. If new account information is reported to a bureau between two score pulls, the later score will reflect this updated data. Creditors typically update information monthly, so a score pulled just before an update will differ from one pulled immediately after.
Both FICO and VantageScore have released multiple versions of their scoring models over time. For instance, FICO 8 is currently the most widely used FICO version, but older versions like FICO 2, 4, and 5 are still prevalent in specific sectors like mortgage lending. Similarly, VantageScore has versions such as 3.0 and 4.0 that are commonly in use. Different lenders or free credit monitoring services may utilize different versions of these models, which can result in score variations even when based on the same underlying credit report data.
Why These Differences Matter
For consumers, understanding these score differences is important due to lender preferences and practical application. Most traditional lenders, including banks and mortgage companies, predominantly rely on FICO scores for their lending decisions, especially for significant loans. While VantageScore has gained traction and is used by a growing number of financial institutions, FICO often remains the primary score for determining loan approvals and interest rates.
Free credit monitoring services frequently provide VantageScores. These are useful tools for consumers to track general credit health and monitor for changes. However, they are best utilized for overall financial awareness rather than as a precise indicator of whether a specific loan application will be approved. The score provided by a free service might not be the exact score a lender uses.
Instead of focusing on minor fluctuations between different scores, consumers should concentrate on foundational credit habits that positively influence any scoring model. Consistently making on-time payments is a significant factor across both FICO and VantageScore models. Maintaining low credit utilization also has a substantial positive impact on both scores. By responsibly managing credit, individuals can improve their overall credit profile, leading to higher scores regardless of the specific model used.
