How to Use

This cloud migration cost estimator gives you an approximate price comparison across the three major cloud providers. Enter your infrastructure specifications — number of servers, vCPUs, RAM, and storage — along with your expected data transfer volume.

Include the labor hours you expect to spend on migration (planning, testing, reconfiguring, and cutover) and your hourly rate for engineers. The calculator shows monthly costs for each provider, an estimated on-premise comparison, the one-time migration cost, and total first-year spend.

Note that these are simplified estimates based on standard pay-as-you-go pricing. Actual costs may vary based on reserved instances, discounts, specific instance types, and additional services.

Pricing Methodology

The estimates use simplified pricing models based on standard pay-as-you-go rates:

  • AWS: (vCPUs × $30) + (RAM GB × $4) + (Storage GB × $0.10) + (Data Transfer GB × $0.09) × number of servers
  • Azure: (vCPUs × $32) + (RAM GB × $3.50) + (Storage GB × $0.08) + (Data Transfer GB × $0.087) × number of servers
  • GCP: (vCPUs × $28) + (RAM GB × $3.75) + (Storage GB × $0.12) + (Data Transfer GB × $0.12) × number of servers

On-premise costs are estimated as 30% higher than the most expensive cloud provider. First-year total includes 12 months of cloud costs plus the one-time migration labor expense.

Frequently Asked Questions

Pricing varies by workload configuration. Google Cloud typically offers the lowest compute costs with competitive pricing per vCPU. Azure tends to be more expensive for compute but offers lower storage costs. AWS provides the most flexible pricing options including spot and reserved instances. Always compare based on your specific workload.
A simple lift-and-shift of 10 servers typically costs $20,000-$50,000 in professional services and labor. More complex migrations with application rearchitecture can cost $100,000-$500,000+.
Cloud can be 20-40% cheaper than on-premise when you account for hardware replacement, power/cooling, IT staff, and capacity planning overhead. However, for predictable steady-state workloads, on-premise can sometimes be cheaper.
Lift-and-shift (rehosting) is the simplest migration strategy where you move applications and data to the cloud with minimal changes. It's faster and less risky than rearchitecting, but may not take full advantage of cloud-native features.
