Average credit card debt is a household-level statistic: it captures what the typical Illinois household carries on revolving credit, not what an individual owes. Total non-mortgage household debt in Illinois (which includes auto loans, student loans, and personal loans alongside credit cards) averages $44,300, 7% higher than the national average of $41,500.

Illinois consumer debt is concentrated in the Chicago metro; downstate averages run noticeably lower than the state-level figures.

At Illinois's median household income of $80,306 and the state average credit card balance of $6,726, the average debt-to-income ratio on credit card debt alone runs 8.4%. That is the share of one year's pre-tax income that the typical Illinois household has tied up in revolving consumer debt. For households over 36% total DTI (including mortgage, auto, and student debt), lender risk thresholds typically apply and refinancing or new credit becomes harder.

Paying off $6,726 of credit card debt at a typical 22% APR with a minimum-only payment takes roughly 25-30 years and costs more in interest than the original principal. Accelerating the payoff is the question every Illinois household with a balance faces. The right strategy — snowball, avalanche, or hybrid — depends on the portfolio composition, not on a one-size-fits-all rule.
