Pricing

R2 charges based on the total volume of data stored, along with two classes of operations on that data:

  1. Class A operations which are more expensive and tend to mutate state.
  2. Class B operations which tend to read existing state.

There are no charges for egress bandwidth.

All included usage is on a monthly basis.

  • Storing 2 GB for 15 days will be charged as 1 GB-month.

​​ Class A operations

Class A Operations include ListBuckets, PutBucket, ListObjects, PutObject, CopyObject, CompleteMultipartUpload, CreateMultipartUpload, ListMultipartUploads, UploadPart, UploadPartCopy and PutBucketEncryption.

​​ Class B operations

Class B Operations include HeadBucket, HeadObject, GetObject, UsageSummary, GetBucketEncryption and GetBucketLocation.
