Azure Virtual Machine Cost Estimator

Estimate your monthly Azure Virtual Machine (VM) costs based on compute, operating system, reserved instance terms, and managed disk storage. This calculator provides a simplified estimate and does not include networking, backup, monitoring, or other ancillary Azure services.

Understanding Azure Virtual Machine Costs

Azure Virtual Machines (VMs) are one of the most fundamental compute services offered by Microsoft Azure. They provide on-demand, scalable computing resources without the need to purchase and maintain physical hardware. However, understanding their pricing can be complex, as it depends on several factors.

Key Factors Influencing Azure VM Costs:

1. VM Series and Size: Azure offers a wide range of VM series (e.g., B-series for burstable workloads, D-series for general purpose, E-series for memory-optimized) and sizes within each series. Each size has a different number of vCPUs, RAM, and temporary storage, directly impacting its hourly rate.
2. Operating System: The choice between Linux and Windows significantly affects cost. Linux VMs generally have a lower compute cost as they don't incur Windows Server licensing fees, which are bundled into the Windows VM hourly rate.
3. Region: Azure pricing varies by geographical region due to differences in infrastructure costs, energy prices, and local market conditions.
4. Reserved Instances (RIs): For predictable, long-running workloads, Azure Reserved Instances offer substantial discounts (up to 72% or more) compared to Pay-As-You-Go rates. You commit to a 1-year or 3-year term for a specific VM size and region.
5. Managed Disks: VMs require storage for their operating system and data. Azure Managed Disks come in various types (Standard HDD, Standard SSD, Premium SSD, Ultra SSD) with different performance characteristics and pricing models, typically charged per GB per month.
6. Networking: Data transfer (egress) out of Azure datacenters incurs costs. Ingress data transfer is generally free.
7. Other Services: Costs can also arise from backup solutions, monitoring services, public IP addresses, load balancers, and other integrated Azure services.

How This Calculator Works:

This estimator focuses on the core compute and managed disk costs for an Azure VM. It allows you to select a VM series/size, operating system (implied by the VM selection), a reserved instance term, and managed disk specifications. It then calculates an estimated monthly cost based on simplified pricing models for demonstration purposes.

• VM Series and Size: Choose from common VM configurations. The hourly rate for compute and OS is factored in.
• Reserved Instance Term: Select Pay-As-You-Go for standard hourly billing, or a 1-year or 3-year Reserved Instance for potential discounts on the compute portion.
• Managed Disk Type and Size: Specify the type and capacity of the storage disk attached to your VM.
• Monthly VM Uptime (Hours): Enter the number of hours per month your VM is expected to run. For 24/7 operation, 730 hours is a common approximation for a 30-day month.

Example Calculation:

Let's say you want to run a Standard_D2s_v3 (Linux) VM for a full month (730 hours) with a 1-Year Reserved Instance and a 128 GB Standard SSD.

• VM Hourly Rate (D2s_v3 Linux, Pay-As-You-Go): ~$0.09/hour (example rate)
• 1-Year RI Discount: ~30% (example discount)
• Discounted VM Hourly Rate: $0.09 * (1 – 0.30) = $0.063/hour
• Monthly VM Cost: $0.063/hour * 730 hours = ~$45.99
• Standard SSD Cost (128 GB): ~$0.05/GB/month * 128 GB = ~$6.40/month (example rate)
• Total Estimated Monthly Cost: $45.99 (VM) + $6.40 (Disk) = ~$52.39

This example illustrates how different selections impact the final cost. Remember that actual Azure pricing can vary and should be checked on the official Azure pricing pages for the most accurate figures.
