Pricing Calculators: TCO and Azure Pricing

Before you spend a dollar on Azure, use these two calculators. The Pricing Calculator estimates Azure costs. The TCO Calculator compares cloud vs on-premises.

Two calculators, two purposes

☕ Simple explanation

Think of buying a car vs keeping your old one.

Pricing Calculator = the dealership’s price configurator. “A blue sedan with leather seats and GPS costs $35,000.” It shows you what specific Azure resources will cost.

TCO Calculator = a comparison sheet. “Keeping your old car costs $8,000/year in repairs and fuel. A new electric car costs $5,000/year in charging and maintenance. You’d save $3,000/year by switching.” It compares your current on-premises costs with what Azure would cost.

Use the Pricing Calculator when you know what you want to build in Azure. Use the TCO Calculator when you’re deciding whether to move to Azure in the first place.

Azure Pricing Calculator (azure.microsoft.com/pricing/calculator/) estimates the cost of specific Azure resources. You select services, configure sizes and options, and get a monthly cost estimate. It’s used for budgeting and architecture planning.

Total Cost of Ownership (TCO) Calculator (azure.microsoft.com/pricing/tco/calculator/) compares the total cost of running workloads on-premises versus in Azure. It factors in hardware, software, electricity, labour, networking, and facility costs that are easy to overlook when comparing against cloud pricing.

The Pricing Calculator in practice

Summit Construction wants to estimate the cost of running their project portal in Azure. They configure:

ResourceConfigurationEstimated Monthly Cost
2x D2s v5 VMsLinux, Australia East$140
Azure SQL DatabaseStandard, 50 DTU$75
Blob Storage100 GB, Hot tier, LRS$2
Load BalancerStandard$18
Outbound bandwidth50 GB/month$4
Total estimate~$239/month

Key features:

  • Add multiple services to a single estimate
  • Adjust region, tier, and configuration
  • Export estimates as Excel for budget approval
  • Save and share estimates via link

The TCO Calculator in practice

Before migrating, Summit Construction’s CFO asks: “Will this actually save us money?”

The TCO Calculator compares:

Cost CategoryOn-Premises (3 Years)Azure (3 Years)
Hardware$45,000 (servers + UPS)$0 (included)
Software licences$12,000 (Windows, SQL)$8,640 (included in pricing)
Electricity$5,400$0 (included)
Cooling$2,700$0 (included)
IT labour$36,000 (part-time admin)$12,000 (reduced)
Networking$3,600$1,440
Total$104,700$22,080
Savings~$82,620 (79%)

Key exam concept: The TCO Calculator accounts for “hidden” on-premises costs that organisations often forget: electricity, cooling, physical space, IT labour, hardware lifecycle, and software licence maintenance. The true cost of on-prem is typically much higher than just the hardware price tag.

💡 Exam tip: Which calculator for which scenario?

Pricing Calculator:

  • “Estimate how much a deployment will cost” → Pricing Calculator
  • “How much will 3 VMs and a SQL database cost per month?” → Pricing Calculator

TCO Calculator:

  • “Compare on-prem vs cloud costs” → TCO Calculator
  • “Build a business case for migration” → TCO Calculator
  • “What will we save by moving to Azure?” → TCO Calculator

Don’t confuse them — the exam tests whether you know which calculator to recommend.

Question

What is the TCO Calculator used for?

Click or press Enter to reveal answer

Answer

Comparing the total cost of running workloads on-premises vs in Azure. It includes hidden costs like electricity, cooling, labour, and facility expenses that aren't obvious in a simple price comparison.

Question

What hidden costs does the TCO Calculator include that the Pricing Calculator does NOT?

Click or press Enter to reveal answer

Answer

Electricity, cooling, physical facility costs, IT labour, hardware lifecycle replacement, software licence maintenance, and networking infrastructure. These make on-premises appear cheaper than it actually is.
