What Is Considered Credit Card Debt: Purchases to Unpaid Balances

Credit card debt is everything the issuer bills to your account: the purchases you make, the interest that accrues on any balance you carry, fees and penalties the issuer adds, cash you withdraw against the credit line, and balances you transfer in from another card. Because a credit card is an unsecured revolving line of credit, no collateral backs any of it, and every one of these items sits on the same statement and grows interest the same way.

Purchases

The base layer is your purchase balance, the running total of goods and services charged to the card. When you use the card, the issuing bank pays the merchant and you owe the bank that amount. Your available credit drops by the purchase and rises again as you pay, which is why these accounts are called revolving.

Nothing you buy with a credit card serves as collateral. If you fall behind, the bank can’t repossess the item you charged; its options are to keep billing you, sell the debt to a collector, or sue for a judgment.¹ Federal law requires the issuer to send a periodic statement each billing cycle showing your previous balance, new charges, payments, and the amount now owed.²

Interest and Finance Charges

Interest is the cost of borrowing, and it becomes part of the debt the moment it posts. Your card’s Annual Percentage Rate sets the amount. Most issuers calculate it daily: they divide the APR by 365 to get a daily rate, multiply by your average daily balance, and add the result to what you owe.³ As of early 2026, the average credit card APR sits around 18.71%, though rates can range from roughly 12% to over 34% depending on the card and your credit.

Because interest is calculated on the full balance, including previously accrued interest, the debt compounds. If you only make the minimum payment, most of that payment goes to interest and barely dents what you originally spent. Your statement must include a Minimum Payment Warning showing how long it would take to pay off the balance at the minimum, the total cost of doing so, and the monthly amount needed to clear the balance in 36 months.⁴

Grace Periods

A grace period is the window between the close of a billing cycle and the payment due date during which you can pay the full statement balance and avoid interest. If a card offers one, the issuer must deliver your statement at least 21 days before the grace period expires.⁵ The grace period only applies when you pay in full. Carry any balance forward and most issuers start charging interest on new purchases immediately, until you clear the account again.

When the Rate Can Change

Federal law limits when an issuer can raise the APR on money you already owe. The rate on an existing balance generally can’t be increased unless a variable-rate index moves, a disclosed promotional rate expires, or a payment is more than 60 days late.⁶ If the rate went up because of a late payment, the issuer must drop it back within six months once you make on-time payments during that period.

Fees and Penalties

Every fee that posts to your statement is part of the debt, treated exactly like a purchase. If you owe $500 and a $30 late fee posts, you now owe $530, and interest accrues on the full amount.

Late Payment Fees

A late fee is charged when you miss the minimum by the due date. Federal regulations set a safe harbor ceiling. As of the most recent adjustment, issuers can charge up to $30 for a first late payment and up to $41 for another late payment on the same type of violation within the next six billing cycles.⁷ These figures are adjusted periodically for inflation. Issuers can charge less, or perform their own cost analysis to justify a different amount, but the fee can’t exceed the minimum payment you missed.⁸

Other Fees That Land on Your Balance

Annual fees. Some cards charge a yearly membership fee that posts whether or not you use the card.
Foreign transaction fees. Purchases in a foreign currency or processed through a foreign bank often carry a surcharge, commonly around 3% of the transaction. Some cards waive it.
Over-limit fees. If your card permits transactions above your credit limit, the issuer can charge a fee each time you exceed it, but only if you opted in.
Returned payment fees. If your payment bounces, the issuer can charge a penalty fee subject to the same safe harbor limits as late fees.

Cash Advances

A cash advance is money you pull against your credit line, whether from an ATM, a convenience check, or certain cash-equivalent transactions. Advances typically carry a fee of 3% to 5% of the amount (or a flat minimum, whichever is higher) plus a separate, higher APR than purchases. And there is usually no grace period. Interest starts the day you take the money.

Withdraw $1,000 with a 5% fee and your debt jumps to $1,050 immediately, with interest accruing on the full amount from day one. The combination of the fee, the higher rate, and no grace period makes cash advances the most expensive slice of credit card debt.

Balance Transfers

A balance transfer moves debt from one credit card to another, usually to chase a lower or promotional rate. The original creditor gets paid off, but the obligation doesn’t disappear. You now owe the new issuer the transferred amount plus a balance transfer fee, typically 3% to 5% of the amount moved.

Move a $5,000 balance with a 3% fee and you owe the new card $5,150. Promotional 0% APR windows can save real interest, but the standard APR kicks in on whatever remains once the promotion ends. If the promotional rate was disclosed upfront, the issuer can apply the higher rate to the leftover balance when the window closes.⁶

Store Card Balances and Deferred Interest

Private-label store cards, the kind you can use only at a specific retailer, create the same type of unsecured revolving debt as a general-purpose credit card. The retailer or a partner bank is the creditor, and the same repayment rules apply. These accounts often carry higher APRs, sometimes above 30%. The Fair Credit Billing Act still applies, so you have the same right to dispute billing errors and unauthorized charges.

Many store cards advertise “no interest if paid in full” within 6, 12, or 18 months. That is a deferred interest offer, not a true 0% APR. With deferred interest, the issuer tracks interest from the original purchase date. Pay the full balance before the promotional period ends and the interest is waived. Leave even a small balance when it expires and you owe every dollar of interest that accrued over the whole period, not just interest going forward. Federal regulations require clear disclosure of this, and any ad using phrases like “no interest” must include “if paid in full” nearby.⁵

Who Is Legally Responsible for the Balance

The primary cardholder, the person who opened the account, is always on the hook for the full balance. Liability for anyone else attached to the account depends on their role.

Authorized users can charge purchases but are not legally obligated to pay. Only the primary cardholder is. Any private arrangement between the two doesn’t change who the bank pursues.
Joint account holders are each fully liable for the entire balance. Joint credit card accounts have become rare among major issuers but still exist.
Spouses in community property states may be liable for credit card debt incurred during the marriage even if they were not on the account. Rules vary by state.

When a cardholder dies, the balance doesn’t vanish. It becomes a claim against the deceased person’s estate, paid from estate assets during probate before any inheritance is distributed. Relatives generally aren’t personally responsible unless they co-signed, held a joint account, or live in a community property state where the debt qualifies as a marital obligation. Collectors can contact certain people, such as a spouse, parent of a minor, or the executor, but must make clear that payment is being sought from estate assets, not personal funds.⁹

What Happens if the Debt Goes Unpaid

Miss minimum payments for roughly four to six months and the issuer will typically charge off the account, an internal accounting step that marks the debt as a loss. You still owe the money. The issuer may sell the debt to a collector, and either the original creditor or a debt buyer can sue you. A court judgment can authorize wage garnishment, bank account levies, or liens on property.¹

Federal law caps how much of your paycheck a creditor can take on a credit card judgment. Garnishment can’t exceed the lesser of 25% of your disposable earnings for the week, or the amount by which your weekly disposable earnings exceed 30 times the federal minimum hourly wage.¹⁰ Some states set stricter limits, and a handful prohibit wage garnishment for credit card debt entirely.

Every state also sets a statute of limitations on how long a creditor can sue you to collect. It generally runs three to six years, though a few states allow up to ten. Once that window closes, the debt is time-barred and can no longer be enforced by lawsuit. The debt still exists and can appear on your credit report for up to seven years. Making a payment on old debt can restart the clock in some states, so check your state’s rule before paying anything on a long-dormant account.
