Cardholder Agreement: APR, Fees, Disputes, and Arbitration

A cardholder agreement is the binding contract between you and your credit card issuer, and you accept its terms the moment you activate or use the card. It controls every interest charge, every fee, every right you have when a charge is wrong, and whether you can take the issuer to court at all. Federal law dictates much of what has to be in the document and how it must be presented, but issuers fill in the details, and a few clauses buried past the headline rates quietly set the outer limits of your financial exposure on the account.

What the Agreement Has to Show You Up Front

Federal regulations require issuers to present key terms in a standardized summary table known as the Schumer Box, named for the law’s chief sponsor.¹ It appears in application materials and account-opening disclosures and gives you a snapshot of interest rates, fees, and grace-period terms before you read the rest.²

The rest of the agreement fills in what the summary leaves out: how interest is calculated, when rates can change, what happens if you default, whether you’ve agreed to arbitration, and what the issuer can do to modify or close the account. None of it is thrilling reading. All of it is enforceable.

Interest Rates

Your agreement lists several APRs, each tied to a specific type of transaction. The purchase APR covers everyday spending. The cash advance APR applies to cash withdrawals, typically runs several points higher, and has no grace period, so interest starts accruing the day you pull cash. A balance transfer APR covers debt you move from another card, sometimes at a promotional rate that expires on a set date.

Most card rates are variable, meaning they’re pegged to an index like the prime rate and move when the index moves.³ An issuer doesn’t need to warn you before a variable rate rises because the index did the raising. Fixed rates can only change after the issuer gives you a 45-day notice.

Penalty APR

If you fall more than 60 days behind on a minimum payment, the issuer can impose a penalty APR, which frequently lands around 29.99% and can apply to both your existing balance and new purchases.⁴ It isn’t permanent by default. The issuer must reevaluate the increase at least every six months, and if your payment history warrants it, the rate has to come back down.⁵ If you make on-time minimum payments for six consecutive months after the penalty rate kicks in, the issuer must terminate the increase on your existing balance entirely.

First-Year Protections

During the first year after you open an account, the CARD Act generally prohibits the issuer from raising your APR or fees. The exceptions are narrow: a variable rate rising because its index rose, a disclosed promotional rate ending on schedule, your account going more than 60 days delinquent, or the completion of a workout or hardship arrangement.³ After the first year, the issuer can raise rates on new purchases with 45 days’ notice, but it still can’t retroactively raise the rate on an existing balance unless you’re more than 60 days late.

Fees

Late Fees

Federal regulations cap late fees through a safe-harbor system. The issuer can charge a set amount for a first offense and a higher amount for a second missed payment of the same type within six billing cycles, with the dollar amounts adjusted annually for inflation.⁶ After recent CPI adjustments, first-offense amounts sit in the low-$30 range and subsequent-offense amounts in the low-$40 range.⁷ Whatever the safe-harbor figure, a late fee can never exceed the minimum payment that was due.

Over-Limit Fees

An issuer cannot charge you for exceeding your credit limit unless you’ve affirmatively opted in to over-limit coverage. The opt-in has to be a separate, documented decision, and you can revoke it at any time.⁸ If you never opted in, the transaction may simply be declined at the register, which is usually the better outcome anyway.

Foreign Transaction Fees

Purchases in a foreign currency or routed through a foreign bank often carry a fee of 1% to 3% of the transaction. Some cards waive it, and the waiver shows up in the Schumer Box. If your card charges the fee, it applies to every qualifying purchase, so costs add up quickly on a trip abroad.

Annual and Balance Transfer Fees

Annual fees range from zero on basic cards to well over $500 on premium rewards cards. Whether paying one makes sense depends on whether the card’s benefits actually offset the cost for how you use it. Balance transfer fees typically run 3% to 5% of the transferred amount. A 3% fee on a $5,000 transfer adds $150 the day the transfer posts, so do that math before assuming a promotional APR will save you money.

Payments, Grace Periods, and Residual Interest

Your agreement sets a minimum payment, usually a small percentage of the balance plus accrued interest and fees. There’s no federal formula, so the percentage varies by issuer, with most using somewhere between 1% and 3% of the outstanding balance. Paying only the minimum satisfies the contract and stretches your payoff timeline dramatically.

When you pay more than the minimum, the issuer must apply the excess to the balance carrying the highest interest rate first, then work down.⁹ This is one of the more consumer-friendly parts of the CARD Act, and it matters most when you’re carrying a mix of promotional and standard-rate balances.

If your card offers a grace period, the issuer must deliver your statement at least 21 days before the due date.² During that window you owe no interest on new purchases, provided you paid last month’s statement balance in full. Miss a full payment and the grace period disappears: interest accrues on new charges from the transaction date until you’re back to paying in full each cycle.

Even a full payment can leave a small charge on the next statement. That’s residual interest, sometimes called trailing interest. Interest accrues daily between the day your statement is generated and the day your payment posts, and those extra days don’t show up until the next cycle. Clearing it may require two consecutive full payments. If you want to zero out the account exactly, call the number on the back of the card and ask for a payoff amount that includes interest through the current day.

Promotional APR vs. Deferred Interest

Cardholder agreements often include promotional offers, and the difference between the two main types costs people real money.

A 0% introductory APR means no interest accrues on the promotional balance during the promotional period. If you still owe money when the period ends, interest starts accruing on the remaining balance going forward only; nothing is charged retroactively.¹⁰

A deferred interest offer uses language that looks similar: “no interest if paid in full within 12 months.” Pay off the full balance before the deadline and you owe nothing extra. Leave even a dollar unpaid, and the issuer charges all the interest that accumulated from the original purchase date, retroactively. Federal regulations explicitly treat deferred interest programs as different from grace periods, so the retroactive charge is lawful.¹⁰ This structure shows up most on store credit cards.

Disputing Charges and Unauthorized Use

Billing Error Disputes

The Fair Credit Billing Act lets you dispute specific billing errors: charges you didn’t make, charges in the wrong amount, charges for goods you never received or refused, computation errors, and payments the issuer failed to credit.¹¹

To preserve your rights, send a written dispute to the issuer’s billing inquiry address within 60 days of the statement date that first showed the error. Include your name, account number, and enough detail to identify the charge.¹¹ A phone call to customer service doesn’t satisfy the statute, though many issuers will open an investigation on one anyway. Send the letter in addition.

Once the issuer receives your written notice, it must acknowledge within 30 days and resolve the matter within two billing cycles, no more than 90 days. During the investigation you’re not required to pay the disputed amount, and the issuer can’t report it as delinquent or charge interest on it. If the issuer concludes no error occurred, it has to explain the finding in writing and provide documentation on request.¹¹

Unauthorized Use

If someone uses your card without permission, federal law caps your personal liability at $50, and only for unauthorized charges made before you notify the issuer.¹² The cap applies only if the issuer previously gave you notice of your potential liability and a way to report the problem. Most major issuers advertise zero-liability policies that waive the $50 entirely, but those are voluntary policies, not legal guarantees. The $50 is the statutory floor.

Arbitration and Class Action Waivers

Many cardholder agreements include a mandatory arbitration clause: you agree to resolve disputes through a private arbitrator rather than in court. These clauses are enforceable under the Federal Arbitration Act, which treats written arbitration provisions in commercial contracts as “valid, irrevocable, and enforceable.”¹³ Most such clauses also include a class action waiver, so you can’t join or bring a class suit against the issuer either.

The practical effect is real. Arbitration ends your right to a jury trial and usually limits discovery, which makes it harder to build a case around an issuer’s systemic practices.

Some agreements offer a narrow opt-out window, typically 30 to 60 days after you open the account, during which you can send written notice rejecting the arbitration clause while keeping the card. The deadline and address vary by issuer, so check the agreement right after opening the account. Miss the window and the clause binds you for the life of the account. Send the opt-out by a method that gives you proof of the mailing date.

Changes, Credit Limit Cuts, and Account Closure

Term Changes You Can Reject

An issuer must give you at least 45 days’ written notice before making a significant change to your account terms, such as raising a rate or adding a fee. If you reject the change, you can close the account and pay off the existing balance under a repayment method that can’t be less favorable than the options spelled out in the regulation.¹⁴

Credit Limit Reductions

Credit limit cuts don’t require 45 days’ advance notice. An issuer can reduce your limit at any time for almost any reason. If the cut pushes your balance over the new, lower limit, though, the issuer can’t charge an over-limit fee or impose a penalty rate on that basis without first giving you 45 days’ notice of the fee or rate change.¹⁴ The reduction itself can happen without warning, and it can hit your credit utilization overnight.

Closure and Rewards

Either side can close the account. Issuers sometimes close for prolonged inactivity, repeated late payments, or a decline in creditworthiness, and advance notice isn’t always required. Whoever initiates the closure, you remain responsible for any outstanding balance, which must be repaid under the existing terms.

Rewards are a separate problem. Points or cash back accrued inside the card’s own program are often forfeited at closure, though some issuers provide a short redemption window. Points tied to an outside loyalty program, like an airline or hotel, generally survive the card closure but stay subject to that program’s own inactivity rules. If you’re closing a rewards card voluntarily, redeem or transfer first. If the issuer may close it, don’t let large balances sit indefinitely waiting for a bigger redemption.
