Unknown charges from Apple

This is primarily a user-to-user support forum; other Apple users like you. We don't have access to information about charges to your account. See each of the steps in the following instructions. They include information on contacting Apple Support if the other steps don't help: If you see 'apple.com/bill' on your billing statement - Apple Support or go to Subscriptions and Billing - Official Apple Support

What am I being charged for, every month ?

Looks like iCloud+.

Check -> Go to -> Settings -> your name -> iCloud -> if you see 50 GB (or 200 GB or 2 TB) then you have an iCloud subscription.

If you have an iCloud subscription, you will receive a monthly bill from Apple, check your email box.

You pay monthly for iCloud storage.

Raicya’s response is merely a guess. There are many other equally likely possibilities, such as Apple Music or Apple News+. Read the link I provided.
