Understanding VM Costs

Typical Azure VM Costs (Pay-as-you-go):

VM Size vCPUs RAM Cost/Hour Daily (24hr) Monthly
Standard_B1s 1 1 GB $0.01 $0.24 $7.30
Standard_B2s 2 4 GB $0.04 $0.96 $29.20
Standard_D2s_v3 2 8 GB $0.10 $2.40 $73.00
Standard_D4s_v3 4 16 GB $0.20 $4.80 $146.00
Standard_D8s_v3 8 32 GB $0.40 $9.60 $292.00

Additional Costs: - Storage: ~\(0.05/GB/month for disks - **Network**: ~\)0.05-0.10/GB for outbound data - Bastion: ~$140/month if using Azure Bastion

Cost Reduction: - Stop VMs when not in use (saves 100% of compute) - Use Reserved Instances for long-term VMs (save 30-50%) - Use Spot Instances for dev/test (save up to 90%)

Notes

  • Costs are estimates based on Azure pay-as-you-go pricing
  • Actual costs may vary by region and Azure discounts
  • Storage costs continue even when VMs are stopped
  • Network egress charges apply for data transfer
