Cloudflare Pricing (2026) — Workers, KV, R2, D1 & Queues
Cloudflare's developer platform is one $5/month Workers plan plus usage-based pricing on five products. The base plan is cheap; the surprise bills come from misconfigured loops in KV writes, R2 Class A ops, or D1 scans. Each guide below has the official rates, the traps, and a calculator.
Cloudflare Workers
Cloudflare Workers pricing explained: $5/mo Paid plan, $0.30 per million requests, $0.02 per million CPU-ms with 30M included. Free-tier daily limits, real cost examples, and a free calculator.
Cloudflare Workers KV
Cloudflare Workers KV pricing: reads $0.50 per million, writes $5.00 per million, storage $0.50/GB-month. Free-tier daily limits, why write-heavy caches blow up bills, and how to catch a KV cost spike.
Cloudflare R2
Cloudflare R2 pricing: $0.015/GB-month storage, Class A ops $4.50/M, Class B ops $0.36/M, and zero egress fees. Free tier: 10 GB + 1M/10M operations. Infrequent Access rates included.
Cloudflare D1
Cloudflare D1 pricing: 25 billion rows read/month included, then $0.001 per million. 50M rows written included, then $1.00 per million. Storage $0.75/GB-month after 5 GB. How row billing actually works.
Cloudflare Queues
Cloudflare Queues pricing: 1M operations/month included, then $0.40 per million. Each message costs ~3 operations (write, read, delete). Retention, retries, batching, and the real cost-per-message math.
