Cross-region Transfer Cost Calculator

Cross-region traffic (replication, multi-region reads, DR) can generate large bills. Use this calculator to estimate monthly cross-region transfer cost using your own $/GB assumptions.

Inputs

Cross-region transfer (GB / month)
Cross-region price ($ / GB)
Enter your provider’s effective $/GB for the region/path/tier.

Results

Estimated monthly cost
$60.00
Egress
3,000 GB
Price
$0.02 / GB

Example scenario

  • If you replicate 3,000 GB/month across regions at $0.02/GB, estimated transfer cost is $60/month.

Included

  • Cross-region transfer estimate from GB/month and $/GB pricing.
  • Useful for replication, DR, and multi-region architectures.

Not included

  • Provider-specific free tiers, discounts, and tiered steps.
  • Replica storage costs (model separately).

How we calculate

  • Monthly cost = cross-region GB × price per GB.
  • Enter your provider’s cross-region transfer price for the source/destination regions.
  • This page ignores free intra-zone traffic and tiering unless you reflect it in the inputs.

FAQ

Is cross-region transfer the same as internet egress?
No. Providers often price cross-region differently than public internet egress.
Does replication count both directions?
Typically replication traffic is billed on the outbound side. Confirm the billing direction for your service.
