Cloudflare's R2 pricing docs list Standard storage at $0.015 per GB-month, Class A operations at $4.50 per million, Class B operations at $0.36 per million, and no internet egress charges. The free monthly allowance is 10 GB-month of storage, 1 million Class A operations, and 10 million Class B operations. Infrequent Access lowers storage to $0.01 per GB-month but raises operation pricing and adds a $0.01 per GB retrieval charge.
- Cloudflare's docs say there are no egress bandwidth charges for either Standard or Infrequent Access.
- Cloudflare rounds storage, operations, and retrieval to the next billable unit, so small overages can still create cliff effects.
- Infrequent Access is not just cheaper storage; it also carries $9.00 per million Class A operations, $0.90 per million Class B operations, and retrieval charges.
- Migration tools such as Super Slurper are free to use, but the underlying Class A operations and source-bucket charges still apply.
