Pricing (21)

Last updated Apr 21, 2026 Workers KV is included in both the Free and Paid Workers plans.

¹ The Workers Free plan includes limited Workers KV usage. All limits reset daily at 00:00 UTC. If you exceed any one of these limits, further operations of that type will fail with an error.

Note

Workers KV pricing for read, write and delete operations is on a per-key basis. Bulk read operations are billed by the amount of keys read in a bulk read operation.

Pricing FAQ

When writing via KV's REST API, how are writes charged?

Each key-value pair in the PUT request is counted as a single write, identical to how each call to PUT in the Workers API counts as a write. Writing 5,000 keys via the REST API incurs the same write costs as making 5,000 PUT calls in a Worker.

Do queries I issue from the dashboard or wrangler (the CLI) count as billable usage?

Yes, any operations via the Cloudflare dashboard or wrangler, including updating (writing) keys, deleting keys, and listing the keys in a namespace count as billable KV usage.

Does Workers KV charge for data transfer / egress?

No.

What operations incur operations charges?

All operations incur charges, including fetches for non-existent keys that return a null (Workers API) or HTTP 404 (REST API). These operations still traverse KV's infrastructure.
