Understand Cost Management data
This article helps you better understand Azure cost and usage data that's included in Azure Cost Management. It explains how frequently data is processed, collected, shown, and closed. You're billed for Azure usage monthly. Although billing cycles are monthly periods, cycle start and end dates vary by subscription type. How often Cost Management receives usage data varies based on different factors. Such factors include how long it takes to process the data and how frequently Azure services emit usage to the billing system.
Cost Management includes all usage and purchases, including reservations and third-party offerings for Enterprise Agreement (EA) accounts. Microsoft Customer Agreement accounts and individual subscriptions with pay-as-you-go rates only include usage from Azure and Marketplace services. Support and other costs aren't included. Costs are estimated until an invoice is generated and don't factor in credits.
If you have a new subscription, you can't immediately use Cost Management features. It might take up to 48 hours before you can use all Cost Management features.
Supported Microsoft Azure offers
The following information shows the currently supported Microsoft Azure offers in Azure Cost Management. An Azure offer is the type of the Azure subscription that you have. Data is available in Cost Management starting on the Data available from date. If a subscription changes offers, costs before the offer change date aren't available.

Determine your offer type
If you don't see data for a subscription and you want to determine if your subscription falls under the supported offers, you can validate that your subscription is supported. To validate an Azure subscription is supported, sign in to the Azure portal. Then select All Services in the left menu pane. In the list of services, select Subscriptions. In the subscription list menu, select the subscription that you want to verify. Your subscription is shown on the Overview tab and you can see the Offer and Offer ID. The following image shows an example.
Costs included in Cost Management
The following tables show data that's included or isn't in Cost Management. All costs are estimated until an invoice is generated. Costs shown don't include free and prepaid credits.
|Azure service usage5||Support charges - For more information, see Invoice terms explained.|
|Marketplace offering usage6||Taxes - For more information, see Invoice terms explained.|
|Marketplace purchases6||Credits - For more information, see Invoice terms explained.|
|Amortization of reservation purchases7|
5 Azure service usage is based on reservation and negotiated prices.
6 Marketplace purchases are not available for MSDN and Visual Studio offers at this time.
7 Reservation purchases are only available for Enterprise Agreement (EA) and Microsoft Customer Agreement accounts at this time.
How tags are used in cost and usage data
Azure Cost Management receives tags as part of each usage record submitted by the individual services. The following constraints apply to these tags:
- Tags must be applied directly to resources and are not implicitly inherited from the parent resource group.
- Resource tags are only supported for resources deployed to resource groups.
- Some deployed resources may not support tags or may not include tags in usage data – see Tags support for Azure resources.
- Resource tags are only included in usage data while the tag is applied – tags are not applied to historical data.
- Resource tags are only available in Cost Management after the data is refreshed – see Usage data update frequency varies.
- Resource tags are only available in Cost Management when the resource is active/running and producing usage records (e.g. not when a VM is deallocated).
- Managing tags requires contributor access to each resource.
- Managing tag policies requires either owner or policy contributor access to a management group, subscription, or resource group.
If you do not see a specific tag in Cost Management, consider the following:
- Was the tag applied directly to the resource?
- Was the tag applied more than 24 hours ago? See Usage data update frequency varies
- Does the resource type support tags? The following resource types do not support tags in usage data as of December 1, 2019. See Tags support for Azure resources for the full list of what is supported.
- Azure Active Directory B2C Directories
- Azure Firewalls
- Azure NetApp Files
- Data Factory
- Load balancers
- Network Watcher
- Notification Hubs
- Service Bus
- Time Series Insights
Here are a few tips for working with tags:
- Plan ahead and define a tagging strategy that allows you to break costs down by organization, application, environment, etc.
- Use Azure Policy to copy resource group tags to individual resources and enforce your tagging strategy.
- Use the Tags API in conjunction with either Query or UsageDetails to get all cost based on the current tags.

Rated usage data refresh schedule
Cost and usage data is available in Cost Management + Billing in the Azure portal and supporting APIs. Keep the following points in mind as you review costs:
- Estimated charges for the current billing period are updated six times per day.
- Estimated charges for the current billing period can change as you incur more usage.
- Each update is cumulative and includes all the line items and information from the previous update.
- Azure finalizes or closes the current billing period up to 72 hours (three calendar days) after the billing period ends.
The following examples illustrate how billing periods could end.
Enterprise Agreement (EA) subscriptions – If the billing month ends on March 31, estimated charges are updated up to 72 hours later. In this example, by midnight (UTC) April 4.
Pay-as-you-go subscriptions – If the billing month ends on May 15, then the estimated charges might get updated up to 72 hours later. In this example, by midnight (UTC) May 19.
Whether you use the Cost Management APIs, Power BI, or the Azure portal to retrieve data, expect the current billing period's charges to get rerated, and consequently change, until the invoice is closed.
Costs shown in Cost Management are rounded. Costs returned by the Query API aren't rounded. For example:
- Cost analysis in the Azure portal - Charges are rounded using standard rounding rules: values more than 0.5 and higher are rounded up, otherwise costs are rounded down. Rounding occurs only when values are shown. Rounding doesn't happen during data processing and aggregation. For example, cost analysis aggregates costs as follows:
- Charge 1: $0.004
- Charge 2: $0.004
- Aggregate charge rendered: 0.004 + 0.004 = 0.008. The charge shown is $0.01.
- Query API - Charges are shown at eight decimal places and rounding doesn't occur.
Usage data update frequency varies
The availability of your incurred usage data in Cost Management depends on a couple of factors, including:
- How frequently Azure services (such as Storage, Compute, CDN, and SQL) emit usage.
- The time taken to process the usage data through the rating engine and cost management pipelines.
Some services emit usage more frequently than others. So, you might see data in Cost Management for some services sooner than other services that emit data less frequently. Typically, usage for services takes 8-24 hours to appear in Cost Management. Keep in mind that data for an open month gets refreshed as you incur more usage because updates are cumulative.
Historical data might not match invoice
Historical data for credit-based and pay-in-advance offers might not match your invoice. Some Azure pay-as-you-go, MSDN, and Visual Studio offers can have Azure credits and advanced payments applied to the invoice. However, the historical data shown in Cost Management is based on your estimated consumption charges only. Cost Management historical data doesn't include payments and credits. So, historical data shown for the following offers may not match exactly with your invoice.
- Azure for Students (MS-AZR-0170P)
- Azure in Open (MS-AZR-0111P)
- Azure Pass (MS-AZR-0120P, MS-AZR-0123P, MS-AZR-0125P, MS-AZR-0128P, MS-AZR-0129P)
- Free Trial (MS-AZR-0044P)
- MSDN (MS-AZR-0062P)
- Visual Studio (MS-AZR-0029P, MS-AZR-0059P, MS-AZR-0060P, MS-AZR-0063P, MS-AZR-0064P)
