The Wall Street Journal: New FICO changes could lower your credit score

Changes in how the most widely used credit score in the U.S. is calculated will likely make it harder for many Americans to get loans.

Fair Isaac Corp., FICO, +1.00% creator of FICO scores, will soon start scoring consumers with rising debt levels and those who fall behind on loan payments more harshly. It will also flag certain consumers who sign up for personal loans, a category of unsecured debt that has surged in recent years.

The changes will create a bigger gap between consumers deemed to be good and bad credit risks, the company says. Consumers with already-high FICO scores of about 680 or higher who continue to manage loans well will likely get a higher score than under previous FICO versions. Those with already-low scores below 600 who continue to miss payments or accumulate other black marks will experience bigger score declines than under previous models.

The changes are an about-face from recent years, when FICO and credit-reporting companies made changes that helped increase scores for some consumers, such as removing some negative information, including civil judgments, from credit reports.
