What is AWS KMS-Keys?
Last updated: April 10, 2025Each AWS KMS key that you create in AWS KMS costs $1/month (prorated hourly). The $1/month charge is the same for symmetric keys, asymmetric keys, HMAC keys, multi-Region keys (each primary and each replica multi-Region key), keys with imported key material, and KMS keys with a key origin of either AWS CloudHSM or an external key store (XKS). For KMS keys that you rotate automatically or on demand, the first and second rotation of the key adds $1/month (prorated hourly) in cost. This price increase is capped at the second rotation, and any subsequent rotations will not be billed.
