Azure VM economics · GBP retail snapshot

Choose the machines. Then choose the commitment.

Select real Azure VM sizes, quantities, operating systems and runtime patterns. The model uses SKU-level PAYG, reservation and Savings Plan rates rather than generic discount guesses.

Find a VM from requirements

What size do you need?

Find the lowest modelled compute cost among matching sizes in the selected region.

Assumes one VM running 730 hours per month, full commitment use and an unchanged size and region. Low permits B, D, E and F; medium excludes burstable B; high checks compute optimised F only. Family is a rough workload proxy, not a benchmark. Compute only, using the dated GBP retail snapshot. Validate performance, availability and commercial rates before purchase.

One row per VM: VMname,OS,performance,vcpu,ram,disk. Replace the three sample rows in the template. Enter RAM and disk in GiB; disk means one managed disk including the OS volume. Decimal vCPU, RAM and disk values round up before sizing (302.7 GiB becomes 303 GiB, then the next Azure disk tier). Use Linux, Windows or Windows+AHB and low, medium or high. Your CSV is processed in this browser and is not sent to the site.
