Cloudflare costs $5 a month, but the bill is not capped
不追高 (@Ariella1213) writes an X article explaining that Workers Paid’s $5 is a minimum, that per-product limits and budget alerts do not cap the account bill, and how denial-of-wallet requests, write amplification, delayed stops and background retries add cost.

Key points
- The author writes that once Workers Paid usage exceeds included amounts it keeps being billed: Workers requests are listed as “No limit”, D1 bills rows scanned and written, Durable Objects bill requests, duration and storage, and R2 still bills storage, some operations and infrequent-access retrieval.
- She notes budget alerts only send email and do not pause or cap usage, and describes denial-of-wallet: valid requests that trigger paid compute, writes or model calls.
- As a worked example she computes that 10,000 calls writing 100,000 rows each would be about $950 in D1 write overage under current pricing, before indexes, reads, storage and Workers costs.
- She explains that any limit that reads usage before stopping leaves a window that is still billed, compares Vercel’s auto-pause that checks every few minutes, and notes Cloudflare rate-limit counters can lag a few seconds.
- She suggests application-level quota reservation before paid calls and checking retries and background jobs, and writes that these do not cover every cost. Rules checked against official docs on October 8, 2026.
