Global analytics software leader FICO (NYSE: FICO) is elevating findings from a newly released white paper by independent actuarial firm Milliman, which found that FICO® Score 10T is the most predictive credit score for evaluating mortgage default risk. The analysis was performed across all mortgages, including Fannie Mae/Freddie Mac and FHA mortgages, with consistent results across each population.

The Milliman analysis is the first independent, head‑to‑head study to evaluate the predictive performance of two new modern scores, FICO Score 10T and VantageScore 4.0, using a large historical sample of U.S. mortgage originations covering multiple distinct time periods from 2011 to 2023. According to the results of the Milliman study, FICO Score 10T produced higher measures of predictive power and, therefore, risk differentiation across multiple mortgage product types, reinforcing its value for lenders, investors, and the broader housing finance system.

Key findings from the Milliman analysis include:

• FICO® Score 10T performed better, as measured by three calculations of predictive power, across all types of mortgage loans: In an analysis of nearly 20 million mortgages, Milliman found that FICO Score 10T consistently predicted mortgage defaults more accurately than VantageScore 4.0 across all mortgages and individually for GSE and FHA loans.
• The performance advantage was strongest in FHA lending: FICO Score 10T outperformed VantageScore 4.0 by more than 8%1 in FHA lending, the segment that serves first-time homebuyers and underserved borrowers, demonstrating that the more predictive score also delivers the greatest advantage for the people for whom an accurate credit assessment can make or break a path to sustained homeownership.
• FICO Score 10T's performance advantage over VantageScore 4.0 has more than doubled since 2018: The analysis also shows that the performance difference between FICO Score 10T and VantageScore 4.0 is greatest for more recent origination years and generally populations with more observed defaults. For example, in the 2023 GSE loan vintage, FICO Score 10T outperformed by 7.4%, more than double the already impressive 3.4%2 improvement observed on the 2018 vintage. This result highlights the robustness of FICO Score 10T and the time-tested, proven FICO blueprint it is based on that has earned the trust of the mortgage industry for over 30 years.

FICO Score 10T incorporates trended credit data and rental payment information when available in the credit bureau file, offering a more complete view of borrower behavior while avoiding model features of the alternate credit score that disadvantage first-time homebuyers or those without prior homeownership history.

"FICO has been a cornerstone of mortgage credit risk for decades,” said Julie May, vice president and general manager of B2B Scores at FICO. “As we enter a new chapter of credit score policy, the conversation about which score is best should be grounded in facts, specifically, an empirical comparison of the modern scores. The scores use the same data — rental, utility and trended. The difference is in how we use the data and this Milliman study confirms what more than 50 lenders have already seen in practice: our use of the data in FICO Score 10T delivers the strongest predictive performance available for mortgage lending today and can be trusted to continue to deliver that predictive performance for years to come.”

The analysis was prepared independently by Milliman as part of a consulting engagement with FICO, and reflects Milliman’s own methodology and conclusions. The full white paper is available at https://www.milliman.com/en/insight/fico-score-10t-vantagescore-4-analysis-credit-mortgage.
