How can I use Cost Explorer to analyze my spending and usage?

Cost Explorer helps you analyze AWS charges and usage, forecast future billing, and save money by purchasing the right Reserved Instances.

Before you can use Cost Explorer, you must enable it for your account:

  1. Sign in to your account and then access the Billing and Cost Management Dashboard.
  2. From the navigation pane, choose Cost Explorer.
  3. Choose Enable Cost Explorer.

After you enable Cost Explorer, you might need to wait up to 24 hours for cost and usage data to populate. Use one of the pre-configured reports in the Reports drop-down menu to analyze your costs, or create a New Report to fit your needs and save it for later use with Save as.

Here are some common uses for Cost Explorer:

  • To compare previous months' costs with the current month, use the Monthly costs by service report. By default, the chart displays the five services with the highest costs, but the table includes the costs for each service you used.
  • To see the source of a temporary spike in your billing, open the Monthly costs by service report, and under Monthly, choose Daily instead.
  • To see the costs for individual resources that make up a service, open the Service filter, choose the service, and then choose Apply Filters. Then, open Group By and choose Usage Type. For example, to see how much you're billed for data transfer for Elastic Load Balancing, choose the EC2-ELB service, group by Usage Type, and then look for data transfer.
  • To view costs by cost allocation tag, open the Group By menu and choose Tags. Note: The Tags option is not available if you don't have any cost allocation tags. When you create a new cost allocation tag, you might need to wait up to three days for the tag to appear in Cost Explorer.
  • To view unblended cost data for member accounts in an organization, open Show costs as and then choose Unblended costs.
  • To view which member accounts are paying taxes as the master account in an organization, open Group by and choose Linked account, and then open the Service filter and choose Tax.
