Understand Cost Management data
This article helps you better understand Azure cost and usage data included in Cost Management. It explains how frequently data is processed, collected, shown, and closed. You receive a bill for your Azure usage each month. 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 commitment discounts (that is, reservations and savings plans) and third-party offerings, for Enterprise Agreement (EA) and Microsoft Customer Agreement (MCA) accounts. Microsoft Online Services Agreement (MOSA) accounts only include usage from Azure and Marketplace services with applicable commitment discounts applied but don't include Marketplace or commitment discounts purchases. Support and other costs aren't included. Costs are estimated until an invoice is generated and don't factor in credits. Cost Management also includes costs associated with New Commerce products like Microsoft 365 and Dynamics 365 that are invoiced along with Azure.
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 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. Summarized data in cost analysis is only available for the last 13 months. If a subscription changes offers, costs before the offer change date aren't available.

Cost Management data only includes the usage and purchases from services and resources that are actively running. The cost data you see is based on past records. It includes resources, resource groups, and subscriptions that might be stopped, deleted, or canceled. So, it might not match with the current resources, resource groups, and subscriptions you see in tools like Azure Resource Manager or Azure Resource Graph. They only display currently deployed resources in your subscriptions. Not all resources emit usage and therefore might not be represented in the cost data. Similarly, Azure Resource Manager doesn't track some resources so they might not be represented in subscription resources.
How tags are used in cost and usage data
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 aren't implicitly inherited from the parent resource group.
- Resource tags are only supported for resources deployed to resource groups.
- Some deployed resources might not support tags or might not include tags in usage data.
- Resource tags are only included in usage data while the tag is applied – tags aren't applied to historical data.
- Resource tags are only available in Cost Management after the data is refreshed.
- Resource tags are only available in Cost Management when the resource is active/running and producing usage records. For example, when a virtual machine (VM) is deallocated.
- Managing tags requires contributor access to each resource or the tag contributor Azure role-based-access-control (RBAC) role.
- Managing tag policies requires either owner or policy contributor access to a management group, subscription, or resource group.
If you don't see a specific tag in Cost Management, consider the following questions:
- Was the tag applied directly to the resource?
- Was the tag applied more than 24 hours ago?
- Does the resource type support tags? Some resource types don't support tags in usage data. See Tags support for Azure resources for the full list of what is supported.
Here are a few tips for working with tags:
- Plan ahead and define a tagging strategy that allows you to break down costs by organization, application, environment, and so on.
- Group and allocate costs using tag inheritance to apply resource group and subscription tags to child resource usage records. If you're using Azure policy to enforce tagging for cost reporting, consider enabling the tag inheritance setting for easier management and more flexibility.
- Use the Tags API with either Query or UsageDetails to get all cost based on the current tags.
Cost and usage data updates and retention
Cost and usage data is typically available in Cost Management within 8-24 hours. Keep the following points in mind as you review costs:
- Each Azure service (such as Storage, Compute, and SQL) emits usage at different intervals – You might see data for some services sooner than others.
- 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.
- During the open month (uninvoiced) period, cost management data should be considered an estimate only. In some cases, charges might be latent in arriving to the system after the usage actually occurred.
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. There are uncommon circumstances where it might take longer than 72 hours to finalize a billing period.
- 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.
Usage charges can continue to accrue and can change until the fifth day of the month after your current billing period ends, as Azure completes processing all data. If the usage file isn't ready, you see a message on the Invoices page in the Azure portal stating Your usage and charges file is not ready
. After the usage file is available, you can download it.
When cost and usage data becomes available in Cost Management, it gets retained for at least seven years. Only the last 13 months are available from the Azure portal under Cost Management portal under Exports. It's also available in the Cost Details API. To retrieve historical data that is older than 13 months, use the Exports REST API.
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. Charges might change until the invoice is closed.
Cost rounding
Costs shown in Cost Management are rounded. Costs returned by the Query API aren't rounded. For example:
- Cost analysis in the 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.
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. The historical data (closed month data) shown in Cost Management is based on your estimated consumption charges only. For the following listed offers, Cost Management historical data doesn't include payments and credits. Additionally, price changes might affect it. The price shown on your invoice might differ from the price used for cost estimation.
For example, you get invoiced on January 5 for a service consumed in the month of December. It has a price of $86 per unit. On January 1, the unit price changed to $100. When you view your estimated charges in Cost Management, you see that your cost is the result of your consumed quantity * $100 (not $86, as shown in your invoice).
Note
The price change might result in a a price decrease, not only an increase, as explained in this example.
Historical data shown for the following offers might not match exactly with your invoice.

- 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)
