Costco cancels a membership through two documented channels: the membership counter at any warehouse, or Member Services at 1-800-774-2678. The Primary Member makes the request and gets a full refund of the membership fee — immediately in-warehouse, or within several business days by phone. Online you can only remove auto-renewal, which lets the membership lapse at renewal.
Menus and labels can change. If the steps below don’t match what you see, use the official help link on this page.

Call Costco Member Services at 1-800-774-2678.
Ask to speak with a live agent — the Primary Member must make the request.
Request cancellation of your membership and any household cards.

Sign in at Costco.com and verify your membership.
Under 'Account,' choose 'Renew Membership.'
Remove the Visa or Mastercard set for Auto Renew.
Do this at least two business days before the first day of your renewal month so the membership expires instead of renewing (this does not refund the current membership term).
Only official-source troubleshooting notes are included here.
Post-cancellation details like access, downgrade behavior, and refund caveats are shown only when the provider documents them.

Not for an immediate cancel-and-refund. Costco's cancellation page lists only the warehouse membership counter or the Member Services phone line. Online you can remove auto-renewal so the membership lapses at its renewal date, but that does not refund the current term.
Yes. Costco's satisfaction assurance refunds your full membership fee whenever you cancel. In-warehouse cancellations are refunded on the spot; phone or online refund requests typically take several business days. Check current pricing for your tier.
No. There is no fixed-term contract or early-termination fee, so you can cancel any time. To simply let a membership expire without an auto-renew charge, remove auto-renewal at least two business days before the first day of your renewal month.
Only the Primary Member can cancel. Bring your membership card and photo ID to the warehouse counter, or call Member Services at 1-800-774-2678 and verify your identity by phone.
