About the Cloud Migration Cost Estimator
A cloud migration cost estimator helps businesses plan their move to cloud infrastructure by comparing AWS, Azure, and GCP costs side by side. It models compute, storage, networking, data transfer, and migration labor costs.
Quick Start Guide
- Enter your values — Fill in the fields with numbers relevant to your cloud migration cost estimator calculation. Most fields include sensible defaults.
- Adjust settings — Change options like units, rates, or timeframes to match your specific scenario.
- Review results — The output shows a clear breakdown so you understand how the total was calculated.
How It Works
Uses published pricing from AWS, Azure, and GCP for comparable service tiers. Includes compute (vCPU + memory), storage (SSD/HDD by capacity), data transfer (cross-region + internet egress), and estimated migration labor (based on workload complexity).
Real-World Example
Scenario: Migrating a 50-server workload to the cloud
- Compute: 50 VMs (8 vCPU, 32GB each).
- Storage: 10 TB block storage + 5 TB object storage.
- Data transfer: 5 TB/month outbound.
- Migration labor: 200 hours engineering time.

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.
