Understanding Snowflake Data Transfer Billing

Cloud providers apply data egress charges in either of the following use cases:

  • Data is transferred from one region to another within the same cloud provider’s network.

  • Data is transferred out of the cloud provider’s network.

To recover these expenses, Snowflake charges a per-byte fee when users unload data from your Snowflake account (on either AWS or Microsoft Azure) into a storage location (i.e. bucket or container) in another region within the same cloud provider’s network or a different network.

The amount charged per byte depends on the region where your Snowflake account is hosted. For data transfer pricing, see the pricing page (on the Snowflake website).

Note

Note that Snowflake does not charge to load data from any external storage location (i.e. on another cloud provider’s network); however, contact your cloud storage provider (AWS S3, Google Cloud Storage, or Microsoft Azure) to determine whether they apply data egress charges to copy data from their network and region of origin to the cloud provider’s network and region where your Snowflake account is hosted.
