> Clarifies that Iceberg billable-bytes figures are a known Snowflake data-modeling quirk, not an actual charge, and explains the "Bytes" vs "Bytes (Billable)" fields.

## The SELECT app is showing Billable Bytes for Iceberg Tables

Rest assured you are not billed for Iceberg tables. This is a known issue due to how Snowflake has modeled the data. The field called "Bytes (Billable)" in SELECT (charts and tables) comes from the `SNOWFLAKE.ACCOUNT_USAGE.TABLE_STORAGE_METRICS` view, `ACTIVE_BYTES` field. We may choose to zero out this measure for Iceberg in the near future.

## The "Bytes" field in SELECT does not match "Bytes (Billable)" for Iceberg Tables

The "Bytes" field in the SELECT UI comes from the `SNOWFLAKE.ACCOUNT_USAGE.TABLE_STORAGE_METRICS` view, `ACTIVE_BYTES` field. Snowflake has confusingly modeled to only count the metadata storage for Iceberg. Therefore this number is always smaller for Iceberg tables.  


The "Bytes (Billable)" field in the SELECT UI comes from `SNOWFLAKE.ACCOUNT_USAGE.TABLES` view, `BYTES` field. Snowflake has modeled this data to show the total of the physical data files  + Iceberg metadata.
