What is cloud migration cost estimation?
Cloud migration cost estimation is the process of calculating the total investment required to move your IT infrastructure, applications, and data from on-premise environments to cloud platforms like AWS, Microsoft Azure, or Google Cloud Platform. It includes costs for migration planning, application refactoring, data transfer, cloud infrastructure provisioning, training, and the transition period where both environments run simultaneously. Thorough cost estimation prevents budget surprises and helps organizations build a realistic migration business case.
Ready to Move Forward?
Planning a migration is only the first step. Perimattic's cloud migration services handle the end-to-end process — assessment, architecture, migration execution, and post-migration optimisation — so your team stays focused on the business.

What is cloud migration cost estimation?
Cloud migration cost estimation is the process of calculating the total investment required to move your IT infrastructure, applications, and data from on-premise environments to cloud platforms like AWS, Microsoft Azure, or Google Cloud Platform.

Thorough cost estimation prevents budget surprises and helps organizations build a realistic migration business case.
How does this cloud migration cost calculator work?
This calculator evaluates your current infrastructure footprint, the number and complexity of applications to migrate, your target cloud platform, and your preferred migration strategy such as lift-and-shift, re-platforming, or re-architecting. It then applies cloud provider pricing models and migration project benchmarks to estimate total migration costs and projected ongoing cloud operating expenses. The results include a comparison of current on-premise costs versus projected cloud TCO to quantify potential savings.
Is this cloud migration calculator completely free to use?
Yes, this cloud migration cost calculator is entirely free to use, with no payment or subscription required. To view your full estimate and PDF report, you enter your name and work email; your contact details and calculator inputs are then sent to Perimattic so the team can follow up on your estimate. You can model unlimited migration scenarios across different cloud providers and migration strategies to find the most cost-effective approach. The tool is designed to provide transparent, vendor-neutral cost insights for your cloud migration planning.
What information do I need to use this calculator?
You should know the number and types of servers or workloads you plan to migrate, your current compute and storage requirements, and your target cloud provider preference. Understanding your application architecture, database sizes, network bandwidth needs, and compliance requirements will produce more accurate estimates. Current monthly or annual infrastructure spending is also helpful for generating meaningful cost comparison projections.
How accurate are the cloud migration cost estimates?
The estimates provide a realistic planning range based on published cloud provider pricing and data from real migration projects. Actual costs can vary depending on application complexity, data transfer volumes, the level of refactoring required, and hidden dependencies discovered during migration. We recommend using these estimates as a directional guide and supplementing them with detailed discovery assessments and cloud provider pricing calculators for final budgeting.
Can I download or export the cloud migration results?
Yes, you can download your cloud migration cost estimate as a detailed PDF report that includes migration cost projections, ongoing cloud operating costs, and TCO comparison charts. The report is structured for use in migration business cases, executive approvals, and cloud strategy presentations. It includes both one-time migration costs and ongoing monthly cloud expenditure forecasts.
Who should use this cloud migration cost calculator?
This tool is built for IT directors, cloud architects, infrastructure managers, and CIOs planning or evaluating a cloud migration initiative. It is also valuable for finance teams who need to model the capital expenditure to operating expenditure shift that cloud migration entails. Managed service providers and consulting firms can use it to prepare preliminary cost frameworks for client migration engagements.
What methodology does this cloud migration cost tool use?
The calculator uses a workload-based estimation methodology that maps your current infrastructure to equivalent cloud resources using right-sizing principles. It applies published pricing from major cloud providers and factors in migration-specific costs such as data egress fees, parallel running periods, and application refactoring effort. The model incorporates TCO analysis principles from Gartner and Forrester frameworks adapted for cloud-specific financial modeling.
How long does it take to complete the cloud migration cost estimation?
The estimation process takes approximately 4 to 7 minutes depending on the complexity of your infrastructure environment. You enter details about your current workloads and migration preferences through a guided interface, and results are calculated instantly. Having an inventory of your servers, storage volumes, and current infrastructure costs on hand will help you complete the process more efficiently.
How do AWS, Azure, and Google Cloud Platform migration costs compare?
Migration costs across AWS, Azure, and GCP are generally comparable for standard workloads, with differences typically within 10-20% depending on specific service selections and enterprise agreement discounts. AWS offers the broadest service portfolio and migration tooling, Azure provides advantages for organizations heavily invested in Microsoft technologies, and GCP is often price-competitive for data analytics and machine learning workloads. The most significant cost differences usually come from negotiated enterprise pricing, committed use discounts, and the specific mix of services your workloads require.
