# Pricing
Last updated Oct 26, 2026|Copy as Markdown| [View as Markdown](https://developers.cloudflare.com/r2/pricing/index.md)| [Agent setup](https://developers.cloudflare.com/agent-setup/)
R2 charges based on the total volume of data stored, along with two classes of operations on that data:
1. [Class A operations](#class-a-operations) which are more expensive and tend to mutate state.
2. [Class B operations](#class-b-operations) which tend to read existing state.
For the Infrequent Access storage class, [data retrieval](#data-retrieval) fees apply. There are no charges for egress bandwidth for any storage class.
All included usage is on a monthly basis.
Note
To learn about potential cost savings from using R2, refer to the [R2 pricing calculator ↗︎](https://r2-calculator.cloudflare.com/).
## R2 pricing
| | Standard storage | Infrequent Access storage |
| --- | --- | --- |
| Storage | $0.015 / GB-month | $0.01 / GB-month |
| Class A Operations | $4.50 / million requests | $9.00 / million requests |
| Class B Operations | $0.36 / million requests | $0.90 / million requests |
| Data Retrieval (processing) | None | $0.01 / GB |
| Egress (data transfer to Internet) | Free [1](#user-content-fn-1) | Free [1](#user-content-fn-1) |
Billable unit rounding
Cloudflare rounds up your usage to the next billing unit.
For example:
- If you have performed one million and one operations, you will be billed for two million operations.
- If you have used 1.1 GB-month, you will be billed for 2 GB-month.
- If you have retrieved data (for infrequent access storage) for 1.1 GB, you will be billed for 2 GB.
### Free tier
You can use the following amount of storage and operations each month for free.
| | Free |
| --- | --- |
| Storage | 10 GB-month / month |
| Class A Operations | 1 million requests / month |
| Class B Operations | 10 million requests / month |
| Egress (data transfer to Internet) | Free [1](#user-content-fn-1) |
Caution
The free tier only applies to Standard storage, and does not apply to Infrequent Access storage.
### Storage usage
Storage is billed using gigabyte-month (GB-month) as the billing metric. A GB-month is calculated by averaging the *peak* storage per day over a billing period (30 days).
For example:
- Storing 1 GB constantly for 30 days will be charged as 1 GB-month.
- Storing 3 GB constantly for 30 days will be charged as 3 GB-month.
- Storing 1 GB for 5 days, then 3 GB for the remaining 25 days will be charged as `1 GB * 5/30 month + 3 GB * 25/30 month = 2.66 GB-month`
For objects stored in Infrequent Access storage, you will be charged for the object for the minimum storage duration even if the object was deleted or moved before the duration specified.
### Class A operations
Class A Operations include `ListBuckets`, `PutBucket`, `ListObjects`, `PutObject`, `CopyObject`, `CompleteMultipartUpload`, `CreateMultipartUpload`, `LifecycleStorageTierTransition`, `ListMultipartUploads`, `UploadPart`, `UploadPartCopy`, `ListParts`, `PutBucketEncryption`, `PutBucketCors` and `PutBucketLifecycleConfiguration`.
### Class B operations
Class B Operations include `HeadBucket`, `HeadObject`, `GetObject`, `UsageSummary`, `GetBucketEncryption`, `GetBucketLocation`, `GetBucketCors` and `GetBucketLifecycleConfiguration`.
### Free operations
Free operations include `DeleteObject`, `DeleteBucket` and `AbortMultipartUpload`.
### Data retrieval
Data retrieval fees apply when you access or retrieve data from the Infrequent Access storage class. This includes any time objects are read or copied.
### Minimum storage duration
For objects stored in Infrequent Access storage, you will be charged for the object for the minimum storage duration even if the object was deleted, moved, or replaced before the specified duration.
| Storage class | Minimum storage duration |
| --- | --- |
| Standard storage | None |
| Infrequent Access storage | 30 days |
## Basin Catalog pricing
Basin Catalog charges for catalog operations and compaction data processed, in addition to standard R2 storage and operations. For full details, refer to [Basin Catalog pricing](https://developers.cloudflare.com/basin-catalog/platform/pricing/).
## Data migration pricing
### Super Slurper
Super Slurper is free to use. You are only charged for the Class A operations that Super Slurper makes to your R2 bucket. Objects with sizes < 100MiB are uploaded to R2 in a single Class A operation. Larger objects use multipart uploads to increase transfer success rates and will perform multiple Class A operations. Note that your source bucket might incur additional charges as Super Slurper copies objects over to R2.
Once migration completes, you are charged for storage & Class A/B operations as described in previous sections.
### Sippy
Sippy is free to use. You are only charged for the operations Sippy makes to your R2 bucket. If a requested object is not present in R2, Sippy will copy it over from your source bucket. Objects with sizes < 200MiB are uploaded to R2 in a single Class A operation. Larger objects use multipart uploads to increase transfer success rates, and will perform multiple Class A operations. Note that your source bucket might incur additional charges as Sippy copies objects over to R2.
As objects are migrated to R2, they are served from R2, and you are charged for storage & Class A/B operations as described in previous sections.

## R2 billing examples
### Standard storage example
If a user writes 1,000 objects in R2 **Standard storage** for 1 month with an average size of 1 GB and reads each object 1,000 times during the month, the estimated cost for the month would be:
| | Usage | Free Tier | Billable Quantity | Price |
| --- | --- | --- | --- | --- |
| Storage | (1,000 objects) \* (1 GB per object) = 1,000 GB-months | 10 GB-months | 990 GB-months | $14.85 |
| Class A Operations | (1,000 objects) \* (1 write per object) = 1,000 writes | 1 million | 0 | $0.00 |
| Class B Operations | (1,000 objects) \* (1,000 reads per object) = 1 million reads | 10 million | 0 | $0.00 |
| Data retrieval (processing) | (1,000 objects) \* (1 GB per object) = 1,000 GB | NA | None | $0.00 |
| **TOTAL** | | | | **$14.85** |
### Infrequent access example
If a user writes 1,000 objects in R2 Infrequent Access storage with an average size of 1 GB, stores them for 5 days, and then deletes them (delete operations are free), and during those 5 days each object is read 1,000 times, the estimated cost for the month would be:
| | Usage | Free Tier | Billable Quantity | Price |
| --- | --- | --- | --- | --- |
| Storage | (1,000 objects) \* (1 GB per object) = 1,000 GB-months | NA | 1,000 GB-months | $10.00 |
| Class A Operations | (1,000 objects) \* (1 write per object) = 1,000 writes | NA | 1,000 | $9.00 |
| Class B Operations | (1,000 objects) \* (1,000 reads per object) = 1 million reads | NA | 1 million | $0.90 |
| Data retrieval (processing) | (1,000 objects) \* (1 GB per object) = 1,000 GB | NA | 1,000 GB | $10.00 |
| **TOTAL** | | | | **$29.90** |
Note that the minimal storage duration for infrequent access storage is 30 days, which means the billable quantity is 1,000 GB-months, rather than 167 GB-months.
### Asset hosting
If a user writes 100,000 files with an average size of 100 KB object and reads 10,000,000 objects per day, the estimated cost in a month would be:
| | Usage | Free Tier | Billable Quantity | Price |
| --- | --- | --- | --- | --- |
| Storage | (100,000 objects) \* (100KB per object) | 10 GB-months | 0 GB-months | $0.00 |
| Class A Operations | (100,000 writes) | 1 million | 0 | $0.00 |
| Class B Operations | (10,000,000 reads per day) \* (30 days) | 10 million | 290,000,000 | $104.40 |
| **TOTAL** | | | | **$104.40** |

## Frequently asked questions
### Will I be charged for failed requests to my R2 bucket?
Requests that fail during authentication or authorization are not charged. This includes:
- HTTP 401 ( `Unauthorized`) — missing or invalid credentials.
- HTTP 403 when caused by an authentication failure such as `SignatureDoesNotMatch`, `ExpiredRequest`, or `RequestTimeTooSkewed`.
- HTTP 403 ( `AccessDenied`) when valid credentials do not have permission to perform the operation.
Some requests that pass authentication and authorization but fail for other reasons are counted and billed according to the operation's class. For example:
- A `PutObject` returning HTTP 412 ( `PreconditionFailed`) due to a conditional header like `If-None-Match` counts as a Class A operation.
- A `PutObject` returning HTTP 400 ( `BadDigest`) due to a mismatched `Content-MD5` counts as a Class A operation.
## Footnotes
1. Egressing directly from R2, including via the [Workers API](https://developers.cloudflare.com/r2/api/workers/), [S3 API](https://developers.cloudflare.com/r2/api/s3/), and [`r2.dev` domains](https://developers.cloudflare.com/r2/buckets/public-buckets/#enable-managed-public-access) does not incur data transfer (egress) charges and is free. If you connect other metered services to an R2 bucket, you may be charged by those services. [↩](#user-content-fnref-1) [↩2](#user-content-fnref-1-2) [↩3](#user-content-fnref-1-3)
