The $8 late fee never took effect. The $17 billion did.

In 2024, credit card issuers charged Americans more than $191 billion in interest and fees — $17.0 billion of it in late fees alone, the single largest fee category and up 17% from $14.5 billion in 2022, according to the CFPB's 2025 Consumer Credit Card Market Report.▸ More than 45 million cardholders are charged a late fee in a typical year. In March 2024 the Bureau finalized a rule to cut the typical fee from $32 to $8 — then, thirteen months later, agreed to let a federal judge erase it. Now, in July 2026, the CFPB has quietly asked regulators for permission to look at the question again.

Late fees are the largest single fee line item card issuers collect, and the second-largest income source overall behind interest.▸ The CFPB's 2025 market report puts total interest and fees at more than $191 billion for 2024 (derived: $160 billion in interest plus $31.3 billion in fees), of which $17.0 billion — well over half of all fees, and the single largest fee category — was late fees specifically, up 17% from $14.5 billion in 2022. That's up from $11.3 billion in late fees in 2021 and $11.9 billion in 2020, years when issuers ran waiver programs tied to pandemic relief; late-fee volume has kept climbing since.

Nearly 4,000 issuers serve over 190 million cardholders, but the top ten issuers hold more than four-fifths of the balances — meaning the fee income is concentrated too.▸ The report found deep-subprime cardholders hold about 6% of accounts but generate 28% of late-fee volume, almost five times their share.

In March 2024 the CFPB finalized the Credit Card Penalty Fees Rule, lowering the "safe harbor" late fee — the amount issuers can charge without proving it matches their actual collection costs — from $30 (or $41 for a repeat violation within six billing cycles) to a flat $8 for issuers with a million or more open accounts, covering more than 95% of outstanding balances.▸ The Bureau projected the change would save cardholders more than $10 billion a year, an average of $220 per person for the 45+ million people who are charged a late fee.

The U.S. Chamber of Commerce, the American Bankers Association, the Consumer Bankers Association, and two Texas chambers of commerce sued within two days, arguing the CARD Act required penalty fees to be allowed to deter repeat violations, not just cover costs.▸ The case moved to the Northern District of Texas, and the rule was blocked before its effective date. After the change in administration, the CFPB stopped defending the rule; on April 15, 2025, Judge Mark T. Pittman entered a consent judgment vacating it in Chamber of Commerce of the United States of America v. CFPB, No. 4:24-cv-00213-Y — with the Bureau's own agreement that its rule had exceeded its statutory authority. The $30/$41 safe harbor, and the ~$32 average fee it produces, has applied without interruption since.

The reversal might have ended the story.▸ Instead, on July 6, 2026, the CFPB submitted a new Request for Information on "Credit Card Late Fees and Late Payments" (RIN 3170-ZA54) for interagency review — a prerule filing, not classified as economically significant, with no legal deadline attached. An RFI is typically the first procedural step toward a new rule, though the Bureau has not said what shape, if any, a second attempt would take. The document itself had not been publicly released as of this writing.

Dollar figures for 2024 late fees, total fees, and interest are drawn from the CFPB's Y-14+ panel of large issuers, not the entire market; 2022 comparison figures are the same report's own restated prior-period baseline. The combined "interest and fees" total is derived by addition because the report does not state it as a single figure for 2024. Savings estimates for the vacated rule are the CFPB's own projections and were never tested against real-world data because the rule never took effect.
