How to cancel Costco membership

Costco membership is cancelled at any warehouse membership counter or by phone — and Costco refunds the membership fee at any time if you're dissatisfied.

Checked in October 2026 against Costco membership’s own help pages. Costco membership typically costs about €65 a year.

Cancel on the web

Go to the membership counter at any Costco warehouse; you get the refund on the spot.
Or call Member Services on 1-800-774-2678 and ask a live agent to cancel.
Only the Primary Member can cancel.

What happens after you cancel

The membership ends when it's cancelled and refunded.

Refunds

Costco's satisfaction guarantee: it cancels and refunds your membership fee at any time if you're dissatisfied.

Watch out for

Auto-renewal charges on the first day of your renewal month. To stop it without cancelling, contact Member Services at least 72 hours before then.

Make sure the charge really stops

Track Costco membership in Cancely and mark it cancelled: the day before it would have renewed, you get a reminder to check your statement — so a cancellation that didn’t take doesn’t cost you another month.
