Consumers tacked on more than $45 billion of new debt in the fourth quarter alone, the survey said. CardHub projects that new debt will climb above $60 billion this year.
Credit card trends were not entirely glum, though, as defaults reached a six-year low in 2014. However, the average household held a $7,200 card balance at the end of the year.
