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 are not included. Costs are estimated until an invoice is generated and do not factor in credits.

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 will not be 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 that 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, click on 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.

8 Resource tags are applied as usage is emitted from each service and aren't available retroactively to historical usage.

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.

Rerated data

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.

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. As a result, the 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)
