As organizations shift from traditional IT infrastructure to cloud environments, one question arises consistently: "How much will I really save by moving to the cloud?" 

Microsoft answers this through a powerful yet often underutilized tool — the Azure Total Cost of Ownership (TCO) Calculator. Whether you're an IT decision-maker, financial analyst, or a cloud consultant, this tool can be your first step towards justifying cloud migration with data-backed insights. 

 

What is the Azure TCO Calculator? 

The Azure TCO Calculator is a free web-based tool provided by Microsoft that helps organizations estimate the cost savings of migrating workloads from on-premises environments to Microsoft Azure. 

It allows you to: 

• Input your current on-prem infrastructure details 

• Calculate ongoing expenses (hardware, software, electricity, labor) 

• Compare those costs to equivalent Azure services 

• Generate a comprehensive report that breaks down potential savings 

 

Why Use the Azure TCO Calculator? 

Here’s why the TCO Calculator is a must-use tool in your cloud planning phase: 

✅ Cost Visibility 

It provides a clear view of what you're spending now — and what you could be saving with Azure. 

✅ Business Case Justification 

You get a downloadable report that can be presented to stakeholders or leadership to support your migration plan. 

✅ Strategic Planning 

When combined with tools like Azure Migrate, the TCO Calculator helps plan your digital transformation with precision. 

 

How to Use the Azure TCO Calculator (Step-by-Step) 

1. Visit the Calculator 

Go to https://tco.microsoft.com 

2. Add Your Workloads 

Input the number of servers, virtual machines, CPU cores, RAM, and storage currently in use in your on-prem data center. 

3. Customize Your Costs 

Include additional parameters such as: 

• Software licenses (Windows Server, SQL Server) 

• Electricity and cooling costs 

• IT labor rates 

• Networking and storage costs 

4. Review the TCO Report 

Once all data is entered, the tool generates: 

• A detailed cost comparison (On-prem vs Azure) 

• Charts for better visualization 

• Downloadable PDF report for easy sharing 

 

📊 Sample Output 

Here’s what you can expect in your TCO report: 

Category	On-Prem Cost	Azure Cost	Savings
Hardware	$120,000	$0	$120,000
Software Licensing	$80,000	$40,000	$40,000
IT Labor	$50,000	$25,000	$25,000
Power & Cooling	$30,000	$0	$30,000
Total Savings			$215,000

(Actual numbers will vary based on your inputs) 

 

Pro Tips for Accuracy 

• Always use current and realistic figures for hardware, power, and staffing costs. 

• For even better results, pair this tool with Azure Migrate to get a deeper workload discovery and performance insight. 

• Run multiple scenarios to compare different migration strategies (e.g., lift-and-shift vs. modernization). 

 

Conclusion

The Azure TCO Calculator is more than just a budgeting tool — it’s a strategic asset for anyone planning a move to the cloud. It empowers you to build a strong business case backed by numbers, understand hidden costs, and unlock the full potential of cloud efficiency. 

Before taking your next step toward Azure, take 10 minutes to run your TCO estimate. It could save your organization time, money, and a lot of surprises down the road.
