The Historical 12-Month Billing Summary report shows the total AWS costs for each month, as well as statistics about your average AWS costs. The current month is not included in this report, only previous months (if billing data is available). The statistics in the report can be based on CloudWatch data or on your Detailed Billing Report (using Unblended costs).
NOTE: Detailed Billing Reports are only available for CloudCheckr Pro accounts and include details such as costs, credits, net bill, tags, and service type. For instructions on enabling the Detailed Billing Report within AWS, please go here: https://support.cloudcheckr.com/enable-aws-detailed-billing/
NOTE: Monitoring for your charges must be enabled within your AWS account for CloudCheckr to be able to report on your AWS bill. For instructions on enabling monitoring within AWS, please go here: https://support.cloudcheckr.com/enable-aws-billing-monitoring/
If you are using Consolidated Billing, within the Payer Account you will see a dropdown listing all the other accounts for which this account is a payer.
The Source of billing data dropdown allows you to view the report using CloudWatch data or Detailed Billing data.
Using CloudWatch data:
CloudWatch provides the capability to monitor your AWS Bill by querying the CloudWatch API. Using this CloudWatch data has some limitations. It does not provide any information on tags, credits, or break out the information other than by service. As well, updates from Amazon to CloudWatch are occasionally delayed for a day or two, resulting in lumpiness in the AWS Bill. If the AWS billing system delays your CloudWatch data for two days, the costs will all appear in the second day and the costs will be misleading.
Using Detailed Billing Reports:
We recommend you enable Detailed Billing in AWS and use the Detailed Billing Report (BETA) to provide more accurate billing reports.
AWS also provides Detailed Billing Reports which write into a file on S3 the complete details of your charges, credits, and net bill. Enable the Detailed Billing by following the directions here.
The latest billing information from AWS is often not pushed to the Detailed Billing Reports for several days, particularly at the beginning or end of the month. You will not see your AWS Billing information in the CloudCheckr Billing reports until it is updated in your Detailed Billing reports from AWS.
The Summary section provides the following information:
Average Monthly Bill – shows, on average, your AWS costs each month that CloudCheckr has billing data for.
Average Daily Bill – shows, on average, your AWS costs each day that CloudCheckr has billing data for.
Age of Billing History – shows the beginning date that CloudCheckr has billing data for.
The Monthly Bill section is a bar chart displaying the total monthly Costs, Credits, and Net Bill when using Detailed Billing. When viewing CloudWatch data, you will see the Net Bill for each month.
The bottom of the report provides a list of monthly Costs, Credit, and Net Bill for each of the past twelve months (or for however many months CloudCheckr has billing data for).
