Cancellation guide
How to cancel Costco membership
A clear, step-by-step guide to cancelling your Costco membership membership, plus the things worth checking before you leave.
Before you cancel
- There's no fixed contract, so you can cancel anytime. Your access simply runs to the end of the period you've paid for.
- Expect to be offered a retention discount or loyalty deal to make you stay. If you're sure you want to cancel, stand your ground.
- Cancel before your next renewal date to avoid being charged for another period.
- Cancel from the account you actually pay with, and make sure you're the billing owner before you start.
- Get a confirmation (on-screen or by email) and keep it as proof of the date you cancelled.
