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.

Storage usage

Storage is billed using gigabyte-month (GB-month) as the billing metric. A GB-month is calculated by recording total bytes stored for the duration of the month.

For example:

  • Storing 1 GB for 30 days will be charged as 1 GB-month.
  • 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, UploadPart, and UploadPartCopy.

Class B operations

Class B Operations include HeadBucket, HeadObject, and GetObject.

Free operations

R2 billing examples

Example 1

If a user writes 1,000 objects in R2 for 1 month and each object is 1 GB in size and requested 1,000 times per month, the estimated cost for the month would be:

UsageFree TierBillable QuantityPrice
Class B Operations(1,000 objects) * (1,000 reads per object)10,000,0000$0.00
Class A Operations(1,000 objects) * (1 write per object)1,000,0000$0.00
Storage(1,000 objects) * (1GB per object)10 GB-months990 GB-months$14.85

Example 2

If a user writes the same 1 GB object 1,000,000 times a day and the object is read 10,000,000 times a day, the estimated cost in a month would be:
