Fair Isaac Corp., maker of the popular FICO credit score used by most lenders, says its new scoring model will do a better job predicting the likelihood of a borrower defaulting on a loan. For one thing, the new model, dubbed FICO 08, will be more forgiving of occasional slips by consumers, but will take a harder line on repeat offenders. Fair Isaac predicts its new system will help lenders reduce default rates on their consumer credit by between 5% and 15%.

Consumers could start seeing the new FICO scores by the spring, though some lenders may take additional time to test the system to see how it works with their business and loan portfolios. Fair Isaac, which last revamped its scoring model earlier this decade, says it is accelerating its FICO 08 rollout, partly in response to lenders' demand for better risk-management tools.

The latest version of the FICO score will largely look and feel the same to consumers and lenders. Scores will still range from 300 to 850 -- the higher the better -- and the model will continue to look at the same factors, including consumers' level of credit indebtedness and payment histories, length of credit histories, number of recent credit openings and inquiries, and the type of credit used, to determine scores.

But the new model will more finely slice and dice the information in consumers' credit files to do a better job of separating the "good risks" from the "bad risks," particularly for subprime borrowers; those with "thin," or young, credit files; or consumers who are actively seeking new credit. "Those are the communities that lenders are most interested in" to determine credit risk, says Craig Watts, spokesman for Fair Isaac.

 

FICO 08 also aims to curtail the growing business of allowing people to polish their credit by "piggybacking" on someone else's good credit history. In recent years, credit-repair Web sites have sprung up that arrange for subprime consumers to boost their scores by becoming authorized users on accounts held by strangers with better credit. When scoring a consumer, FICO 08 won't take into consideration credit-card accounts for which that person is an authorized user. But the move also will hurt legitimate users: People who give a credit card to a child or a spouse as an authorized user to help boost their credit score.
