The gym kept charging after you cancelled — but not every month after your cancellation is disputable, and not every month before it is owed. The split is one piece of contract math: your cancellation proof date plus your contract notice period equals your effective cancellation date. A month billed before that date was still owed when billed; a month billed on or after it is disputable. There is no universal gym notice period — the tool takes yours from your contract — and no outcome is guaranteed. Enter your dates and get the month-by-month split, with the deadlines that actually bind each side.

Every number below is either your contract's own number, which you enter, or a law or network rule named beside it. Where a number belongs to someone else's clock, it says so.
| Clock | Who sets it | The rule |
|---|---|---|
| Effective cancellation date | Your contract | Cancellation proof date + the contract notice period in days. Billed before this date = owed; billed on or after it = disputable. A bill dated on the effective date itself counts as disputable in this checker, because the membership ends on that date. |
| FCBA written notice (credit cards) | Federal law, 15 U.S.C. 1666 | Written notice of a billing error to the creditor's billing-inquiries address within 60 days after the statement containing the error was transmitted. Runs from the statement date, not the charge date. |
| Regulation E error notice (debit) | Federal law, 12 CFR 1005.11 | Notice of an error no later than 60 days after the institution sends the periodic statement on which the error first appears. Runs from the statement date, not the charge date. |
| Network filing window | Card-network norm, not a law | About 120 days from the transaction for most dispute conditions. Labelled a norm on every use: your issuer's own deadline governs, so ask for it in writing. |
| Click-to-cancel | State law only — no federal rule in force | The FTC's 2024 click-to-cancel rule was vacated by the Eighth Circuit on July 8, 2025 (Custom Communications, Inc. v. FTC, 142 F.4th 1060) and has not been replaced. State automatic-renewal laws are the live layer: California requires online cancellation for online sign-ups (Bus. & Prof. Code 17602(d)(1)); New York and Colorado have their own automatic-renewal rules. Check your state and your contract — neither replaces the notice period. |
Two traps, both expensive. The first is disputing the wrong months: a month inside the notice period was owed when billed, and disputing it does not make it free — it hands the gym a balance it can pursue, including through collections, even if a chargeback on a genuinely post-cancellation month is won. A chargeback win does not cancel a contract. The second trap is the label: a membership you authorised and later cancelled is a cancelled-recurring dispute (Visa 13.2, Mastercard 4841), never a fraud claim. Describing an authorised charge as fraud or unauthorised can get the dispute denied outright. Dispute only the months on the disputable side of your effective date, and label them for what they are.
No universal notice period: none exists, and any page quoting one for all gyms is guessing about your contract. No gym-chain cancellation window: no chain's own terms were read for this build, so no chain is named and no chain number is printed. No collections timeline or collections law: the warning is the trap itself — a balance the gym says is owed may be pursued, including through collections — hedged to what the sources support. No state deadline, penalty or enforcement claim beyond the California, New York and Colorado existence flags above. No issuer deadline as a single number: the issuer's own deadline governs. No outcome, percentage or guarantee: the verdict bands are Owed, Disputable and Mixed only.
The month-by-month math worked through, the proof hierarchy, the state-law layer without the federal myth, and the collections trap in full — with the checker above the fold.
