VM Count -10%: Monthly Cost $403.29

VM Count Current: Monthly Cost $440.32

VM Count +10%: Monthly Cost $477.35

Formula: Monthly cost = VM count * hourly VM rate * hours + VM count * disk GB * disk price + egress GB * egress price + fixed monthly charges.

About this Azure VM Monthly Cost Calculator

Azure VM spend depends on VM size, region, uptime, disk storage, outbound bandwidth, and support or licensing fees. This calculator makes each assumption visible.

Who this calculator is for

  • Cloud engineers estimating monthly VM spend.
  • IT managers comparing reserved and pay-as-you-go scenarios.
  • Finance teams reviewing cloud budget assumptions.

When to use it

  • Estimate steady-state VM cost.
  • Compare always-on and scheduled runtime.
  • Separate compute, storage, bandwidth, and support cost.

How to use this calculator

  1. Enter VM count and hourly price from your pricing source.
  2. Set expected monthly runtime hours.
  3. Add OS disk, data disk, egress, and fixed monthly charges.
  4. Review monthly and annual totals.

Key assumptions

  • Pricing is flat and user-entered.
  • Taxes, discounts, reservations, marketplace images, and region-specific tiers are not inferred.
  • Inputs are not stored or transmitted.

How this calculator works

Compute cost = VM count x hourly VM rate x monthly hours. Disk cost = VM count x disk GB x price per GB-month. Total monthly cost adds compute, disk, egress, and fixed charges.
Monthly cost = VM count * hourly VM rate * hours + VM count * disk GB * disk price + egress GB * egress price + fixed monthly charges.

Inputs explained

Hourly VM rate

Your entered compute price for the selected VM size, region, OS, and commitment.

Monthly hours

Expected powered-on hours per VM in the month.

Disk and egress prices

User-entered storage and outbound transfer rates from your contract or pricing page.

Understanding your results

The total monthly cost is a planning estimate. Compare compute cost against storage and egress to see which driver matters most.

Example scenarios

Small production pool

Three VMs running 730 hours with 128 GB OS disks, 512 GB data disks, and moderate egress produces a repeatable monthly cost estimate.

Key Features

  • Instant Calculation
  • Private & Secure
  • Mobile Optimized

Tips & Best Practices

  • Run a second scenario with scheduled runtime for nonproduction VMs.
  • Use the exact region and OS rate from your billing source.
  • Include backup and monitoring charges separately when they are material.

Frequently Asked Questions

Does this use live Azure prices?
No. Enter your current VM, disk, and egress rates so the estimate stays accurate when provider pricing changes.
Does this include reservations or savings plans?
Only if you enter a discounted hourly rate that already reflects those terms.
Is any infrastructure data stored?
No. The calculation runs locally in your browser and does not upload your inputs.
