Ever wonder which states have the most credit card debt? California is the highest credit card debt state by total owed while the highest credit card debt state by average balance owed per borrower is Alaska. Both states dominant each statistic. Of the $857 billion currently owed by all U.S. consumers, Californians owe a eye-popping $122.5 billion. Alaskans owe an average of $7,045 on their credit cards – ouch! Among the high balance states, Colorado ranks second after Alaska with an average credit card balance of $5,728. However, booming “Weed” sales may close that gap.
