Azure Cost Optimization Calculator

Model Azure Reservation, rightsizing, managed disk, and bandwidth savings on retail pricing. Published-list estimate only. The math runs in your browser — your numbers never leave this page.

Assumptions

Computed on your device. No accounts, no bill upload, nothing sent to a server or any vendor.

Scenario result

Budget for monitoring alongside infrastructure

Monitoring is a separate line item. Use the Datadog pricing calculator to model log, metric, trace, RUM and synthetic-check usage before comparing monitoring plans. Published-list scenarios are not an invoice or vendor quote.

Worked example

Example inputs: a fixed Microsoft Azure scenario, evaluated by the same engine used by this calculator.

The modeled baseline is $28,447.76/mo; the bounded scenario models $12,853.13/mo in savings and ends at $15,594.63/mo.

Cost classification: Modeled savings
Dominant cost driver: compute ($22,148.20/mo)
Decision rule: Commitment sized to post-rightsize compute. Committing to the original baseline would over-commit ~15% to capacity you're removing — binding for the term.
Scope / sensitivity: rightsize→storage→egress→commit so commitment is sized to real need. Commitments are binding; rates are representative scenarios, not quotes.

Signal	Result
Scenario monthly cost	$15,594.63/mo
Modeled monthly change	$12,853.13/mo savings
rightsize compute	$3,322.23/mo — compute -15% (applied first)
reduce egress	$2,282.90/mo — egress -40% (tiered recompute)
commit:reserved 3yr	$7,248.00/mo — 70% of rightsized compute @ ~55% (scenario)

Example inputs only, not a quote or your bill. Static output is generated from the real calculator engine at build date 2026-10-13 and carries the same valid-before boundary 2026-10-24. If source evidence becomes stale or the example contains an unpriced resource, this block suppresses the computed total instead of publishing a confident number.

Decision guidance

Azure cost decisions this calculator can test

This scenario models East US Linux virtual machines, managed disks, provisioned performance, bandwidth, and Azure Reservation coverage as separate billable meters. The sequence reduces removable usage before it applies a long-term commitment.

Questions it answers

How much virtual-machine spend remains after rightsizing before Azure Reservation coverage is considered?
Does moving a managed disk tier or reducing separately provisioned performance actually change the storage invoice?
How much bandwidth spend changes after the free allowance and tiered rates are recalculated?

When it returns zero or refuses a claim

Unknown VM sizes and disk products are not silently mapped to a similar SKU; the estimate is suppressed.
A disk migration cannot claim savings for capacity that is not present, and a more expensive target is rejected.
Reservation savings are calculated from the rightsized compute baseline so removed capacity is not committed for one or three years.

Verify against your invoice

Reconcile VM family, size, count, and running hours against Cost Management exports.
Check managed-disk capacity and any separately billed performance against the disk invoice lines.
Verify bandwidth by billing zone and size Reservation coverage only after operationally safe rightsizing has been completed.
