Enabling Cost Explorer
You can enable Cost Explorer for your account using this procedure. After you enable Cost Explorer, AWS prepares the data about your costs for the current month and the last three months, and then calculates the forecast for the next three months. The current month's data is available for viewing in about 24 hours. The rest of your data takes a few days longer. Cost Explorer updates your cost data at least once every 24 hours.
If your account is a linked account in a Consolidated Billing family, the payer account must enable Cost Explorer. For more information about Consolidated Billing, see Paying Bills for Multiple Accounts Using Consolidated Billing.
Cost Explorer is enabled for your account automatically if you are signed up to receive detailed billing report with resources and tags through programmatic billing access. Enabling Cost Explorer, however, does not enable programmatic billing access.
