Try this scenarioLoads these inputs into the calculator so you can change them.

The Standard storage example writes 1,000 objects, stores them all month, and reads each one 1,000 times. The published total is $14.85.

On the Free plan this model comes to $14.85. The other plan, with the same inputs, comes to $19.85. The 30-day month is the same length R2 uses in its storage example. Daily free caps are not monthly pools.

R2 does not charge egress

Bandwidth out to the internet is free on Standard and Infrequent Access. The bill is storage, Class A, Class B, and Infrequent Access retrieval. The free tier is monthly and applies to Standard only, on both the Free and Paid Workers plans.

Read this before you trust the total

Free plan lines at $0 can still be an outage: error 1027, error 1102, or a D1 quota error. R2 above its monthly free tier is billed on both plans. Durable Object requests round up to the next million, as in Cloudflare's own Example 1, which bills 500,000 requests as 1 million.

This model

$14.85 · Free

Free quotas for Workers, KV, D1, Queues, and Durable Objects reset at 00:00 UTC. A month that averages under the cap can still fail on one busy day. R2 is different: its free tier is monthly, and usage above it is billed on both plans.

R2 storage
$14.85

1,000 used, 10 included. 990 billable, rounded up to 990. Exact charge $14.85, shown as $14.85. R2 rounds billable storage up to the next GB-month. 1.1 GB-month of billable storage is billed as 2. R2 does not charge egress bandwidth.

Assumptions

  • A 30-day month and steady traffic across it.
  • Rates as published on 2026-10-25; taxes excluded.
  • The Free plan does not bill Workers, KV, D1, Durable Objects or Queues. When a daily cap is reached, requests fail until 00:00 UTC instead of costing more.
  • R2 storage adds $14.85 (100% of the bill): you used more than the 10 included.
  • R2 is billed on both plans above its monthly free tier, which is why the Free plan is not $0 here.
  • R2 egress (bandwidth out) is free, so downloads only cost Class B reads.
