Azure Cost Calculator
What will that Azure architecture actually cost per month? Microsoft’s own pricing calculator covers more than 600 services, but it assumes you already know your instance family, your redundancy tier and what a DTU is. This Azure cost calculator takes the faster path: configure the services most bills are made of (virtual machines, App Service, storage, SQL Database, Cosmos DB, Functions, networking and AI), pick a region and a pricing model, and get an itemized monthly and annual estimate on one screen, with a line-by-line breakdown and a comparison of what the same build costs under each commitment model.
Scope matters with cloud estimates, so here is this tool’s: it prices the whole architecture at planning level. If your question is narrower, the sibling tools go deeper: the Azure VM pricing calculator prices virtual machines only, across all six purchase models, and the Azure storage pricing calculator prices Blob Storage tiers, redundancy and operations in detail. Both are linked in the sections below. Every figure here is an estimate from a stated rate table, and the last sections explain exactly where estimates like this one break.
Quick Answer
Key takeaways
- Seven categories make up nearly every Azure bill: compute, storage, databases, serverless and messaging, networking, AI and analytics, and operations (DevOps, monitoring, security). This tool prices all seven in one pass.
- The pricing model discount applies to compute only. Reservations and Hybrid Benefit do not touch storage, egress or AI token lines, which is why a “45 percent off” model rarely cuts a real bill by 45 percent.
- Functions and Service Bus have real free tiers in the math: the first 1 million Function executions and 400,000 GB-seconds, and the first 13 million Service Bus operations, cost nothing here, matching Azure’s published allowances.
- Estimates break in predictable places: egress you did not model, support plans, Windows license premiums, autoscale spikes and AI token growth. The tool’s breakdown exists so you can find which line moved.
How the estimate is built
Each service line is a small, checkable calculation, and the total is their sum. Virtual machines are hourly rate times count times hours per day times 30, with the OS disk priced from a size table (a 128 GB premium disk is $19.09) and each data disk priced as another 128 GB unit. SQL Database is a tier rate times 730 hours, plus storage at $0.115 per GB. Cosmos DB is provisioned throughput at $0.008 per 100 RU/s per hour across 730 hours, plus $0.25 per GB stored. Egress is tiered: 5 GB free, then $0.087 per GB, stepping down at volume. The full method for the two biggest categories is documented by Microsoft in its VM pricing pages and Blob Storage pricing, and this tool’s rates are planning samples aligned to those published lists.
Two modeling choices deserve attention. First, the model multiplier touches only compute-shaped lines (VMs and SQL): a reservation cannot discount your blob storage, and any estimator that applies it to the whole bill is flattering you. Second, region is a multiplier, not a re-price: 1.00 in East US up to 1.40 in Brazil South. That is an approximation of Microsoft’s regional spread, good for planning, not a quote.
Worked example: a single-VM production build
The calculator is pre-filled with a deliberately plain build so every number can be checked by hand: one D8s v3 (8 vCPU, 32 GB) at $0.192 an hour, running 24 hours a day, a 128 GB OS disk, and 500 GB of Hot blob storage, East US, pay-as-you-go.
| Line | Math | Monthly |
|---|---|---|
| VM compute | $0.192 x 1 VM x 24h x 30 days | $138.24 |
| VM OS disk (128 GB) | Size-table price | $19.09 |
| Blob storage, Hot | 500 GB x $0.0184 | $9.20 |
| Everything else | Not configured | $0.00 |
| Total | $166.53/mo ($1,998.36/yr) |
The result panel breaks that same build down further: compute shows $157.33 (the VM plus its disk), storage $9.20, and the service summary table puts VMs at 94.5 percent of the bill. Then the pricing model cards re-price the compute under each commitment: 1-year reserved $127.82 a month (save $38.71), 3-year reserved $104.32 (save $62.21), Hybrid Benefit $138.88 (save $27.65). Notice what those savings are percentages of: the whole $166.53 shrinks by 23 to 37 percent, never by the headline 28 to 45, because disk and storage never move. The tool also generates a first optimization recommendation from the configuration itself; for this build it is the reserved-instance switch, priced at the same $38.71.
Going deeper on the two biggest categories
A whole-estimate tool trades depth for breadth on purpose, and two categories deserve a second, dedicated pass before real money moves. Virtual machines are usually the largest line and the one with the most treacherous pricing model: the Azure VM pricing calculator prices 25 sizes under all six purchase models and models the reservation commitment honestly, including the case where reserving a part-time VM costs more than pay-as-you-go. Storage is the opposite trap: cheap per GB, surprising in operations and egress. The Azure storage pricing calculator prices one workload across all four blob tiers and all redundancy options, which is how you catch an Archive tier that costs more than Hot once reads are counted.
The same discipline applies outside Azure’s meter. If the architecture serves media, the delivery side often costs more than the origin: the streaming cost calculator prices that pattern directly. And once an estimate becomes a running bill, Microsoft’s Cost Management analysis tools are where estimate-versus-actual gets reconciled, line by line, with budget alerts on the categories that drift.
Pay-as-you-go versus commitments, honestly
The model choice is a bet about stability. This is the trade as the tool’s own multipliers frame it:
Staying pay-as-you-go
- Full flexibility: resize, move region or delete tomorrow at no penalty.
- The right default while the architecture is still changing, and for genuinely part-time workloads.
- You pay list for every compute hour, forever, including the steady production VMs that will not change for years.
Committing (reserved, savings plans, Hybrid)
- Real discounts on compute: 0.72x for one year and 0.55x for three years in this tool’s model, with Hybrid Benefit at 0.80x where licenses apply.
- The discount never reaches storage, networking or AI lines, so whole-bill savings land well below the headline rate.
- A wrong commitment is a sunk cost: the reservation outlives the architecture decision that justified it if the team migrates instance families mid-term.
Spot pricing sits outside this trade: at 0.30x in the model it is the cheapest compute in the tool, and it is priced for interruption. Batch jobs, render queues and dev/test fleets that survive eviction keep the saving; anything a customer touches mid-transaction should never be there.
What breaks Azure estimates
Estimates fail in recurring places, and naming them is more useful than another decimal place. Egress is the classic: data leaving Azure is metered, and a chatty architecture can ship more gigabytes than anyone sketched. Support plans are absent from most calculators, including this one, and a production support tier can rival a small VM fleet. The Windows premium surprises Linux-first teams: Windows VMs carry a license cost inside their rate that Hybrid Benefit only removes for license holders. Autoscale adds instances during the spikes nobody modeled, then forgets to remove all of them. And AI lines grow by adoption: token spend doubles when a feature succeeds, prompts bloat, and agents retry. The defense is the breakdown: when the invoice lands, compare it line by line against an estimate built like this one, and the drifting category identifies itself.
What competing calculators miss
We reviewed the top-ranking Azure cost pages for this search before rebuilding this page. Microsoft’s official calculator is authoritative and complete, and it is also a 600-service maze that evaluates one configuration at a time and assumes you know what a DTU is. The strongest editorial competitor prices three scenarios well in static tables, but offers no working tool: you cannot put your architecture into it. Multi-cloud estimators cover Azure as one tab among three and price it shallowly, with storage figures in their own worked examples that do not match published Azure rates.
Winning move 1: a working whole-estimate tool. Thirty-eight inputs across seven categories, priced in one pass, with the free tiers (Functions executions, Service Bus operations, Log Analytics ingestion) modeled rather than ignored.
Winning move 2: commitment cards from your configuration. The model comparison is generated from the build you entered, with savings stated against your total, so the gap between headline discount and whole-bill discount is visible instead of discovered.
Winning move 3: stated limits. The D-series rates in the table are planning samples (the D2s v3 rate in particular runs below some published lists), region is a multiplier rather than a re-price, and support plans are excluded. Each limit is named here and in the tool, with the official calculator linked for the binding quote.
Frequently asked questions
It depends on size, operating system, region and commitment. In this tool’s rate table, a B1s (1 vCPU, 1 GB) runs $3.74 a month on pay-as-you-go in East US at 24 hours a day, a D8s v3 is $138.24 at the same schedule, and a 1-year reservation cuts roughly 28 percent off the compute line. Enter your size and hours in the estimator for your configuration.
Spot VMs, modeled here at about 70 percent off compute, for workloads that survive eviction: batch jobs, dev and test, stateless workers. For steady production, 1-year or 3-year reservations or savings plans are the standard answer. B-series burstable VMs are the cheapest way to run small always-on workloads that do not need full CPU around the clock.
Compute charges stop when a VM is stopped and deallocated, but disks, static IPs and attached services keep billing. Disks are the usual surprise: a stopped VM’s OS and data disks accrue charges until they are deleted, which is why this estimator prices disks as their own lines rather than folding them into the VM.
In the rate table used here, Hot is $0.0184 per GB-month in East US, Cool $0.01, Cold $0.0036 and Archive $0.00099, before operations, retrieval and egress. The tier you pick in an estimate is rarely the whole story by month six, so set lifecycle policies to move aging data down, and price operations in the dedicated storage calculator before choosing Archive.
A program for customers with existing on-premises Windows Server or SQL Server licenses with Software Assurance, letting those licenses cover Azure VMs and SQL services. This tool models it at 0.80 times the compute lines as a planning approximation; the actual saving depends on your license position, and the VM-focused calculator on this site models the license removal exactly for Windows VMs.
The usual reasons: egress that was never modeled, a support plan that no calculator included, a Windows license premium that was not selected, autoscale adding instances during spikes, orphaned resources nobody deleted, and AI token growth after a successful launch. Compare the invoice line by line in Cost Management against an itemized estimate and set budget alerts on the categories that moved.
Yes. Microsoft’s official calculator is free and needs no Azure account for basic estimates, and estimates can be exported or shared by link. This page’s estimator is also free, and exists for the earlier step: a quick multi-service estimate before you build the detailed official one.
No. It is a planning estimator built on a published sample rate table, with region handled as a multiplier and agreement discounts excluded. Use it to shape the architecture and catch the expensive mistakes early, then confirm the final numbers in Microsoft’s official calculator, which applies your agreement pricing exactly.
