How much credit card debt do Americans owe in total?

How to get close to this number

Multiply households by balance. The country has around one hundred and thirty million households, and a household carrying a balance owes several thousand dollars on average — though many carry none. Households times an average balance gives a figure in the trillions.

The comparison in the explanation is the one that gives the figure proportion: this is small next to mortgage debt at roughly ten times the size. Credit card debt dominates public discussion of household finance while being a minority of it, because the interest rate rather than the principal is what makes it painful.

That rate is the point: average card interest above twenty-one percent, against a mortgage in the low single digits. Debt is not a single quantity but a cost of carry, and a trillion dollars at twenty-one percent generates more annual interest than several trillion at four. Always read a debt figure alongside its rate.
