According to the analysis of Federal Reserve statistics and other government data, American households with credit card debts owed an average of $15,706 on their credit cards in August 2015. A recent random sample of 500 American households with credit card debts produced a mean credit card debt of $16,377 with a standard deviation of $3800.
