On iPhone (joined in the YouTube app)

1. In the YouTube app, open Settings, then Purchases and memberships.
2. Tap your membership.
3. Tap Manage Apple Subscriptions.
4. Tap the membership, then Cancel.

Billed by Google but using an iPhone? YouTube says to cancel from a computer or another non-iOS device.

On a computer

1. Go to youtube.com/paid_memberships.
2. Click Manage membership, then Deactivate.
3. Click Continue.
4. Pick a reason, click Next, then Yes, cancel.

If Apple bills you

You can also go straight to Apple's list:

1. Open Settings on your iPhone and tap your name.
2. Tap Subscriptions.
3. Tap YouTube Premium.
4. Tap Cancel Subscription. You may need to scroll down.

No Cancel button means it is already cancelled. Apple's page: apps.apple.com/account/subscriptions

After you cancel

You keep the paid benefits until the end of the current billing period and you aren't charged again. Pausing isn't offered when Apple bills you.
