This is a simple command line tool to get the cost of your Azure subscription. It uses the Azure Cost Management API to get the cost and output the results to the console, text, csv, markdown or JSON. E.g. so it can be used in a workflow to get the cost of your subscription and use it in subsequent steps.
Besides showing the accumulated cost, it can also show daily cost, extract resource (costs) and list budgets.
It can also detect anomalies and trends in the cost, which can be used to further automate reporting.
You can install this tool globally, using the dotnet tool command:
dotnet tool install --global azure-cost-cli When there is a new version available on NuGet, you can use the dotnet tool update command to upgrade:
dotnet tool update --global azure-cost-cli With a --version parameter, you can specify a specific version to install. Use the --no-cache parameter to force a re-download of the package if it cannot find the latest version.
You can invoke the tool using the azure-cost command. You can use the --help parameter to get a list of all available options. Some of the commands have additional parameters which can be shown by adding the specific command with the --help option.
azure-cost --helpWhich will show:

costByResource Show the cost details by resource
costByTag Show the cost details by the provided tag key(s)
dailyCosts Show the daily cost by a given dimension
detectAnomalies Detect anomalies and trends

regions Get the available Azure regions
When you do not specify a subscription id, it will fetch the actively selected one of the
az cliinstead.
If the application is not working properly, you can use the
--debugparameter to increase the logging verbosity and see more details.
This tool uses the Azure Cost Management API to get the cost. Not all subscriptions have access to this API. To check if your subscription has access, you can use the
az account subscription show --subscription-id yourid --query '[subscriptionPolicies.quotaId]' -o tsvcommand. Validate the resulting quota id with the ones on the Microsoft list to see if it is supported. Running the tool with the--debugparameter will also show the quota id that is used.
There is a pretty strict rate limit on the cost api; the calls are retried after a 429 is received, but it might take a while before the call succeeds as it honors the retry time out.
To make the call to the Azure cost API, you do need to run this from a user account with permissions to access the cost overview of the subscription. Further more, it needs to find the active credentials and it does so by using the ChainedTokenCredential provider which will look for the az cli token first. Make sure to run az login (with optionally the --tenant parameter) to make sure you have an active session.
You can use this tool in a GitHub workflow to get the cost of your subscription and store the results in markdown as a Job Summary. This can be used to get a quick overview of the cost of your subscription. Have a look at the workflow in this repository for an example output.

run: dotnet tool install -g azure-cost-cli
- name: Run Azure Cost CLI
run: azure-cost accumulatedCost -o markdown --subscription ${{ github.event.inputs.az-subscription-id }} >> $GITHUB_STEP_SUMMARY
The last step output the markdown to the Job Summary. This can be used to show the cost of the subscription in the workflow summary. Use it on a schedule to get for example a daily overview. Alternatively you can use the -o json parameter to get the results in JSON format and use it for further processing.
This will retrieve the accumulated cost of the subscription. This is the total cost of the subscription since the beginning of the period specified. We will try to fetch the forecast as well and organise by location, type and resource group. You can use the different formatters to get the results in different formats.
azure-cost accumulatedCost -s 574385a9-08e9-49fe-91a2-27660d92b8f5This is the default command when you do not specify a command.
This will retrieve the cost of the subscription by resource. This will fetch the resource details including the meter information. It is up to the formatter how this is returned. Use the json formatter to get the full details.
azure-cost costByResource -s 574385a9-08e9-49fe-91a2-27660d92b8f5 -o jsonIf you are only interested in the cost of the resources, you can exclude the meter details using the --exclude-meter-details parameter.
azure-cost costByResource -s 574385a9-08e9-49fe-91a2-27660d92b8f5 --exclude-meter-detailsDo keep in mind that with the --metric you can either request the ActualCost or the AmortizedCost cost, but not both at the same time. The default is ActualCost.
A resource can be in multiple resource locations, like Intercontinental and West Europe. When you use --exclude-meter-details, the resource will be listed once and the locations will be combined.
You can parse out the resource name, group name and subscription id from the ResourceId field. The format is /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/{resourceProviderNamespace}/{resourceType}/{resourceName}.
This will retrieve the cost of the subscription by the provided tag key(s). So if you tag your resources with, e.g. a cost-center or a creator, you can retrieve the cost of the subscription by those tags. You can specify multiple tags by using the --tag parameter multiple times.
azure-cost costByTag --tag cost-center --tag creatorThe csv, json(c) and console output will render the results, either hierarchically or flattened in the case of the csv export.
If you require more formatters, let me know!
The daily overview fetches the cost of the subscription for each day in the specified period. It will show the total cost of the day and the cost per dimension. The dimension is the resource group by default, but you can specify a different one using the --dimension parameter.
For example:
azure-cost dailyCosts -s 574385a9-08e9-49fe-91a2-27660d92b8f5 --dimension ResourceLocation
The default dimension is the resource group.
azure-cost dailyCosts 
The above screenshots show the default console output, but the other formatters can also be used.
The available dimensions are: ResourceGroup,ResourceGroupName,ResourceLocation,ConsumedService,ResourceType,ResourceId,MeterId,BillingMonth,MeterCategory,MeterSubcategory,Meter,AccountName,DepartmentName,SubscriptionId,SubscriptionName,ServiceName,ServiceTier,EnrollmentAccountName,BillingAccountId,ResourceGuid,BillingPeriod,InvoiceNumber,ChargeType,PublisherType,ReservationId,ReservationName,Frequency,PartNumber,CostAllocationRuleName,MarkupRuleName,PricingModel,BenefitId,BenefitName
Based on the daily cost data, this command will try to detect anomalies and trends. It will scan for the following anomalies:
- Cost that is stopped; although it is good that the cost is stopped, it might be an indication that something is wrong.
- Cost that is appearing; the cost was not there before and is now adding to the overall cost.
- A spike in cost; a deviation from the normal cost pattern
- A gradual increase in cost; so a service is growing in cost over time.
There are a number of settings you can use to finetune the detection.
--dimension ResourceGroupName The grouping to use. E.g. ResourceGroupName, Meter, ResourceLocation, etc. Defaults to ResourceGroupName
--recent-activity-days 7 The number of days to use for recent activity. Defaults to 7
--significant-change 0,75 The significant change in cost to use. Defaults to 0.75 (75%)
--steady-growth-days 7 The number of days to use for steady growth. Defaults to 7
--threshold-cost 2 The thresshold cost to use. Values lower than this are excluded. Defaults to 2.00
All the different formatters can be used to output the data, so you can further process it with the JSON or CSV output, send it via email with the text formatter, or use the markdown formatter to include it in a GitHub workflow. The console output will render the different anomalies in different and point out the moment in time where the anomaly was detected.
azure-cost detectAnomaliesThis will retrieve the available budgets for the subscription. It will show the current status of the budget and the amount of the budget. As well as listing the configured notifications.
azure-cost budgets -s 574385a9-08e9-49fe-91a2-27660d92b8f5 Retrieve a list of available regions. Besides the location and supported compliances, it will also show the available sustainability information.
azure-cost regionsNot all the formatters are supported for this command. Let me know if there is a need.
With the --filter option you can pass in one or more properties to filter on.
azure-cost --filter "ResourceGroupName=yourresourcegroup;myresourcegroup" --filter "owner=me" In the example above, we look for resources in either yourresourcegroup or myresourcegroup and having a tag named owner with the value me.
Filters are passed along to the Cost API, so less data is retrieved. Compared to the query, where the data is queried with a JMESPATH expression and can be projected as well.
Multiple filters are combined with an and expression, while the values are split by the ; and used as an or.
Use the --query to specify a JMESPath expression. This allows you to filter the results. For example, to get the yesterday cost of the subscription, you can use the following query:
azure-cost -s 574385a9-08e9-49fe-91a2-27660d92b8f5 -o json --query "totals.yesterdayCost"Or to list only the resource groups:
azure-cost -s 574385a9-08e9-49fe-91a2-27660d92b8f5 -o json --query "ByResourceGroup[*].[ResourceGroup, Cost]"will output:
[["mindbyte-sand-api",28.94824],["rg-test",16.457219149662315],["rg-weu",0.252499694771765],["cloud-storage-westeu",0.183537445632]]For the JMESPath parsing, it uses the JMESPath.Net library. Not all constructions might be implemented yet. If you find a query that does not work, please open an issue with a reproducable path at their repo.
The default timeframe is the billing month to date. You can specify a custom timeframe using the --from and --to parameters and setting the -t custom. The timeframe is specified in the ISO 8601 format.
Other options are:
- BillingMonthToDate
- Custom
- MonthToDate
- TheLastBillingMonth
- TheLastMonth
- WeekToDate
These options are based on the types exposed by the query API.
The tool supports multiple output formats. The default is Console which will output the results to the console. You can specify a different format using the --output parameter. The different commands generate different outputs using the specified formatter. The following formats are supported:
The default output format. It will output the results to the console in a graphical way. For example the accumulated costs:
The Json format is great for further processing of the data. It will output the results in a JSON format to the console. Using the > operator, you can redirect the output to a file. Use jsonc to get a colorized output.

Since the tool operates on a single subscription only, you will need to loop over multiple subscriptions yourself. You can do this by using the az account list command and then using the --subscription parameter to switch between subscriptions.
az account list --query "[].id" -o tsv | while read -r id; do
echo "Subscription: $id"
azure-cost accumulatedCost -o markdown -s $id
doneOr using Powershell
az account list --query "[].id" -o tsv | ForEach-Object {
Write-Host "Subscription: $_"
azure-cost accumulatedCost -o markdown -s $_
}Or this snippet by @EEN421 to get the cost by resource for each subscription and append it to a single CSV file.
#Connect to Azure
Connect-AzAccount -UseDeviceAuthentication -Tenant xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx
#Pull list of Subscriptions
$ids = Get-AzSubscription -TenantId xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx| Select-Object id,name
$firstid = $ids | Select-Object -first 1
$remainingids = $ids | Select-Object -skip 1
#Create CSV for first subscription with header
$firstoutput = azure-cost costByResource -s $firstid.id -t Custom --from 2023-05-01 --to 2023-05-31 -o csv
Add-Content ".\report.csv" $firstoutput
#Loop through remaining subscriptions and append to CSV
Foreach ($id in $remainingids) {
$output = azure-cost costByResource -s($id.id) -t Custom --from 2023-05-01 --to 2023-05-31 -o csv --skipHeader
Add-Content ".\report.csv" $output
}Using the --skipHeader parameter is important here, otherwise you will get a header for each subscription which will mess up the output file as it will append the data to the same file.
No, the calls to the Azure Cost APIs are free, although there are some rate limits in place. Avoid pulling data too often as it will only be refreshed every 4 hours.
