One TB of compressed Snowflake storage costs about $23 to $40 per month, depending on cloud provider, region, and pricing agreement.
Snowflake measures storage after compression and bills the average amount stored during the month. The calculation is separate from warehouse compute credits. A warehouse can therefore add substantial compute cost even when storage remains near 1 TB.
Time Travel and Fail-safe can increase the stored volume because historical data remains available for recovery. Permanent tables include a Fail-safe period, while transient and temporary tables do not. Clones can also contribute to storage when they contain changed data.
Use storage usage views to compare the average compressed volume with the invoice period. A single day's measurement is not a monthly estimate. Snowflake documents storage costs and Time Travel storage.
