How to avoid charged for customer master keys (CMKs) by Raj Gupta

Customer master keys (CMKs) are used with the AWS Key Management Service (AWS KMS).You are billed for all active or disabled CMKs on your account.

To see a list of the CMKs on your account, choose Customer managed keys in the AWS KMS console. To stop the charges for the CMK delete the CMK.

Note:- you need to schedule the deletion of CMKs once you schedule for deletion then you are not going to charge but if you cancel the deletion schedule before deletion of key then it will again charge you.


Any services that you configured that use the CMK as part of their function will be affected if you are going to delete the CMKs.

schedule period :-  Min:- 7 days to Max:- 30 days, default period is 30 days
