Cloudflare R2 Standard: storage $0.015 / GB-month, Class A $4.50 / million, Class B $0.36 / million, egress free. Free tier (Standard only): 10 GB-month + 1M Class A + 10M Class B / month. Infrequent Access: storage $0.01 / GB-month, Class A $9.00 / million, Class B $0.90 / million, data retrieval $0.01 / GB, egress free, no free tier, 30-day minimum storage duration. Cloudflare rounds usage up to the next billing unit — cross-check the official R2 calculator. Example (Standard, 500 GB, 1M Class A, 40M Class B): storage max(0,500−10)×$0.015 = $7.35; Class A $0; Class B $10.80; egress $0 → ~$18.15.
