GCP egress cost calculator
Enter your monthly data transfer out and get the exact Google Cloud egress cost, tier by tier. Premium Tier rates are $0.12/GB for the first 1 TB after a 1 GB free allowance, dropping to $0.08/GB above 10 TB. Every figure is recomputed from the published GCP network pricing tiers.

[01]The tiers the calculator uses
GCP internet egress is volume-tiered: every GB is billed at the rate of the band it falls into, so your effective rate falls as monthly volume rises. These are the Premium Tier rates to North American destinations. Official GCP source →

[02]What the headline rate leaves out
The calculator models Premium Tier internet egress. A real GCP bill shifts once you account for cross-zone traffic, Cloud CDN, and the choice between Premium and Standard Tier.
Compare GCP against AWS, Azure, and zero-egress alternatives
GCP Premium Tier is the priciest hyperscaler at entry volume; Cloudflare R2 is zero egress at every volume. Run the same number across all providers, or read the full GCP reference for the Standard Tier advantage and Cloud CDN.
[03]Frequently asked
Q.01How do I calculate GCP egress cost?
›
Subtract the 1 GB monthly free allowance from your data transfer out, then bill the remainder against Google Cloud Premium Tier internet egress tiers: $0.12/GB for the first 1 TB, $0.11/GB for the next 9 TB (1-10 TB), and $0.08/GB above 10 TB. So 1 TB/month costs $122.76, 10 TB costs $1,136.53, 50 TB costs $4,413.36, and 100 TB costs $8,509.36 in base Premium Tier egress. The calculator above does this tier math automatically.
Q.02How much does 1 TB of GCP egress cost?
›
1 TB (1,024 GB) of internet data transfer out of Google Cloud at Premium Tier costs $122.76 per month to North American destinations. After the 1 GB free allowance, 1,023 GB is billed at the first-tier rate of $0.12/GB. That is GCP's headline networking, the most expensive of the three hyperscalers at entry volume. Standard Tier (public-internet routing, for non-latency-sensitive traffic) is cheaper at $0.085/GB after a 200 GB free allowance.
Q.03Is GCP egress cheaper than AWS?
›
Not at Premium Tier. GCP charges $0.12/GB versus AWS's $0.09/GB for the first 1 TB, so at low volume GCP is the most expensive hyperscaler. At 10 TB/month, Premium Tier GCP costs $1,136.53 versus $912.60 on AWS. GCP's real edge is Standard Tier networking at $0.085/GB, slightly under AWS's $0.09/GB, available for workloads that tolerate public-internet routing rather than Google's private backbone.
Q.04What costs does this GCP egress calculator not include?
›
It models standard Premium Tier internet egress to North American destinations on the tiered rates. It does not add cross-zone (within-region) traffic at $0.01/GB each way, Cloud CDN cache-fill and lookup fees, Cloud Interconnect or peering charges, or the cheaper Standard Tier rates. It also does not model the higher per-GB rates to Asia-Pacific, Australia, or China destinations. See the full breakdown on the GCP egress reference.
