Snowflake Data Transfer Cost Documentation (2026)

Official Snowflake documentation on data transfer costs and egress pricing.

Key facts surfaced (2026-05-05):

• Data ingestion into Snowflake: free (no ingress charge).
• Same-region data transfer: free.
• Cross-region data transfer: charged per-byte; typical range ~$20/TB (US regions) to ~$140/TB (some Asia Pacific regions).
• Charges are triggered by: COPY INTO commands exporting to external object storage, and cross-region account replication.
• Egress Cost Optimizer (ECO) launched April 2025: caches data in Snowflake-managed storage after first egress, enabling replication to additional regions at zero additional cost — up to 96% savings on cross-region replication workloads.

Relationship to existing KG nodes:

• Supports vendor.snowflake with concrete egress cost detail not currently in the node body.
• The cross-region egress cost is a meaningful constraint for CDP architectures that replicate Snowflake data across regions (e.g., EU data residency requirements). No Constraint node exists yet — drafted as a candidate in evolution-log/2026-05-05/web-refresh.md.
