Azure Pricing Calculator and TCO Calculator

Deploying cloud resources without estimating costs first can lead to bill shock — an invoice far larger than expected. Azure provides two free web-based tools to help you predict costs before committing. The Azure Pricing Calculator estimates the monthly cost of a proposed Azure architecture. The Total Cost of Ownership (TCO) Calculator builds a business case for migrating from on-premises by comparing your current infrastructure cost with the projected Azure cost.

The Azure Pricing Calculator (azure.microsoft.com/pricing/calculator) is a free, web-based tool where you add Azure products to a scenario and configure their parameters — region, SKU, usage hours per month, redundancy level — and the tool calculates an estimated monthly cost. You can save estimates, share them with colleagues, and export them to Excel for inclusion in budget proposals.

To build an estimate, search for or browse to each Azure service you plan to use and click Add to estimate. Configure each service's parameters: for a VM, set the region, operating system, instance type, and how many hours per month it runs (730 for always-on). For storage, set the amount of data stored and the redundancy tier. The calculator updates the monthly total in real time as you adjust settings.

The Pricing Calculator lets you compare pricing models side by side for each resource. For VMs, you can toggle between Pay-As-You-Go, 1-Year Reserved, and 3-Year Reserved to see the cost difference immediately. You can also apply Azure Hybrid Benefit for Windows/SQL licences with a checkbox. This makes it easy to model the cost impact of commitment discounts before making purchasing decisions.

The TCO Calculator (azure.microsoft.com/pricing/tco) helps organisations build a financial justification for migrating from on-premises to Azure. You input your current on-premises infrastructure — servers, storage, networking, databases — and the tool models the equivalent Azure deployment cost, factoring in electricity, cooling, datacenter floor space, IT labour, and hardware refresh cycles that cloud eliminates.

In the first step of the TCO Calculator, you define your current on-premises workloads. For servers, you specify the number of physical or virtual servers, their CPU/RAM profile, OS, and SQL Server licences. For databases, you specify the engine and size. For storage, the capacity and type. For networking, the monthly outbound bandwidth. Each entry maps to an equivalent Azure service for cost comparison.

The second step lets you adjust the cost assumptions the calculator uses for your on-premises environment: electricity cost per kWh, hardware costs, software licensing, IT administrator salary, and virtualisation ratio. The defaults are industry averages, but entering your organisation's actual costs produces a more accurate comparison. Adjusting these inputs significantly affects the calculated savings from moving to Azure.

The third step presents a detailed comparison report covering a 5-year time horizon. It shows your projected on-premises costs (hardware, software, electricity, cooling, labour) versus the equivalent Azure costs. The report provides a total cost saving and a percentage reduction, broken down by category. You can download the report as a PDF or PowerPoint slide to present to management and finance as part of a cloud migration business case.

The two calculators serve different audiences. Use the Pricing Calculator when you already know you are deploying on Azure and need to estimate the monthly cost of a specific architecture — useful for architects and developers planning a new project. Use the TCO Calculator when you need to persuade stakeholders to approve a cloud migration by showing total cost savings over several years compared with staying on-premises.

Both calculators support saving and sharing estimates. In the Pricing Calculator, click Save and sign in with a Microsoft account to save the estimate; click Share to get a URL to send to colleagues. You can also click Export to download the estimate as an Excel workbook, which many project managers and finance teams prefer for budget approval workflows. Exported workbooks include a breakdown by service and month.

For infrastructure-as-code users, you can also estimate costs programmatically. The Azure Cost Management APIs and the What-If analysis in Azure Resource Manager can show you what resources an ARM template or Bicep file would create before deploying it. Third-party tools like Infracost integrate with Terraform to provide cost estimates in CI/CD pipeline pull requests, helping teams catch expensive configurations early in the development process.

In this lesson you learned: the Azure Pricing Calculator estimates monthly costs for a proposed Azure architecture, the TCO Calculator builds a migration business case by comparing on-premises versus Azure costs over five years, and both calculators support saving, sharing, and exporting estimates for stakeholder review.
