GCP Migration Cost Calculator
Calculate the true cost of migrating to Google Cloud Platform — including egress fees, parallel running, Kubernetes adoption cost, and the hidden GCP costs most estimates miss.
What drives GCP migration cost
Network egress to GCP
$0.08/GB from most source regions. 100 TB = ~$8,000.
Parallel running period
Both old + new environments for 3–18 months.
GKE / Kubernetes learning
Steeper curve if team is not container-native.
Cloud Interconnect fees
$0.02–$0.05/GB for dedicated private connectivity.
Staff retraining
GCP has distinct services, IAM model, and networking.
BigQuery migration
Analytics workload migration adds significant complexity.

Frequently asked questions
How much does a GCP migration typically cost?
GCP migration costs follow similar patterns to AWS and Azure. Small workload migrations cost $40,000–$180,000. Mid-enterprise migrations typically run $400,000–$3M. Large-scale GCP migrations including re-architecture, training, and Kubernetes/Anthos adoption can exceed $10M. GCP's pricing calculator only covers destination infrastructure — not the significant project costs of getting there.
What are the hidden costs of migrating to GCP?
Commonly underestimated GCP migration costs include: (1) network egress charges from your current environment to GCP ($0.08/GB for the first 1 TB from most regions), (2) Google Kubernetes Engine (GKE) learning curve for teams not yet container-native, (3) Google Cloud Interconnect setup fees for dedicated connectivity ($0.02–$0.05/GB for Dedicated Interconnect), (4) parallel running during the migration window, (5) retraining from AWS or Azure to GCP-specific services, and (6) BigQuery and data warehouse migration complexity for analytics workloads.
Does Google offer GCP migration support or credits?
Yes. Google Cloud offers several migration support programmes. Migration credits and incentive programmes are available through Google's commercial team for enterprise migrations. Google Cloud Architecture Framework and Migration Guide provide free planning resources. Google Professional Services (PSO) offers paid migration support. Google's Migrate for Compute Engine (formerly Velostrata) provides tooling to migrate VMware and other workloads to GCP at reduced cost. Contact your Google Cloud account team or a Google Cloud Partner.
Is GCP cheaper than AWS or Azure for migrations?
GCP often has competitive compute pricing and offers sustained use discounts automatically (no upfront commitment required). However, migration project costs — engineering, retraining, parallel running — are similar across all three providers. The destination cloud running cost comparison depends heavily on workload type: GCP tends to be competitive for containerised and data-heavy workloads; AWS has pricing advantages for certain managed services.
