Understand Your Bill for Windows Azure
The charges for Windows Azure subscriptions vary by rate plan. Some rate plans, such as Windows Azure MSDN, include an amount of service each month at no charge.
For our monetary commitment rate plans, an unused commitment balance at the end of a billing month will be rolled over as a credit to future billing months until the end of your offer term. At the end of the term or upon cancelation during the term, any unused commitment balance will be forfeited.
Some rate plans do not include any base units or an amount included with the offer. For these rate plans, you are charged for all of your monthly consumption.
For more information about consumption, usage, and rate plans, see the Windows Azure Purchase Options page.

Understand the Current Charges
The Current Charges section of the bill contains details about your monthly charges. The links are organized into the following subsections.
Recurring Charges
Recurring charges are the flat monthly charges for your base units if you purchased an offer that includes an amount of service each month at no charge. These recurring charges are billed in advance for your next month’s service. If your subscription does not include base units, you will not have any recurring charges and this section will not display.
Commitment Charges
Commitment charges are flat monthly charges of your commitment amount if you purchased a 6 or 12 month commitment offer. If you elected to pay for your entire commitment up front, then commitment charges represent the entire commitment amount for a 6 or 12 month prepaid commitment offer. The commitment charges are billed in advance for your next month’s service. The service dates are the start and end dates of your commitment period.
Discounts
Discounts show the monetary value of the discount applied to your current bill.

Miscellaneous Adjustments

Total Pre-Bill Adjustments
Total pre-bill adjustments are the total credits applied to your current bill.
Usage Charges
Usage charges are monthly charges for the usage that surpasses the amount included with your offer. You are billed in arrears for your past month’s usage. For subscriptions that have an amount included in the offer, this is also known as overage.
When you view a list of usage charges in your invoice, the following columns display the details of what you are being billed for:
Name
Identifies the top-level service for which this usage belongs. Services include:
- Access Control
- All Services
- Cache
- CDN
- Cloud Services
- Data Management
- Database Storage
- Media
- Networking
- Service Bus
- SQL Database
- SQL Reporting
- Storage
- Web Sites
The service of “All Services” is utilized for any monthly recurring fees for our commitment offers and for non-CDN data transfers that you incur. CDN data transfers are priced separately and are included under the “CDN” service. If you need a breakdown of your usage for data transfers, our daily usage reports have a separate Service field in which you can obtain this information (please refer to the Daily Usage section for more information).
Information on the other services are posted on the pricing details page.
Type
Utilized primarily to further break down Service for the following Windows Azure services:
| Service | Service Type |

| Cache | 1GB |
| Cache | 2GB |
| Cache | 4GB |
| Storage | Geo Redundant |
| Storage | Locally Redundant |
| SQL Database | Business Edition |
| SQL Database | Web Edition |
The Service Type field for Cache indicates the cache size that has been provisioned. For Storage, the Service Type field indicates the level of redundancy of your storage account. Geo redundancy is the default option where data is stored in two sub-regions within the same region. For SQL Azure database, the Service Type field indicates whether you have utilized a Business Edition or Web Edition database.

Consumed
Contains the amount of the resource that has been consumed during the billing period.
Included
Identifies the amount that is included each month with your offer. For offers that include an amount of service each month at no charge, this represents your base units. For example, if you purchased two base units for an offer that included 750 compute hours per base unit, you would have 1,500 hours included each month with your offer.
Billable
If the Consumed amount exceeds the Included amount, this column displays the difference. You are billed for this amount. For pay-as-you-go offers with no amount included with the offer, this total will be the same as the Consumed quantity.

Rate displays the rate you are charged per billable unit.
Disctounted Rate displays the rate you are charged per billable unit if you purchased a 6 or 12 month monetary commitment offer.
Value
Displays the result of multiplying the Billable column by the Rate column. If the Consumed amount does not exceed the Included amount, there will be no charge in this column.
