AWS launches support for amortization of EC2 Capacity Blocks for ML

AWS Data Exports for Cost and Usage Report (CUR) 2.0 and AWS Cost Explorer

AWS has introduced the ability to amortize the upfront fee for Amazon EC2 Capacity Blocks for ML across the duration of each reservation. This update allows users to see the amortized cost of each instance launched into a Capacity Block and the amortized cost of unused capacity. This feature helps attribute the upfront fee to the workloads that used it and identify capacity that went unused.

Previously, the upfront fee appeared as a single charge on the purchase date, making it difficult to see how that cost was spread across usage over the reservation. Now, the amortized cost appears alongside your instance usage, enabling better allocation of GPU costs to the teams, projects, and applications that ran on the reserved capacity. Additionally, users can see what share of their reservation went unused and plan future Capacity Block purchases.

In CUR 2.0, the amortized costs appear in the reservation_amortized_upfront_fee_for_billing_period and reservation_effective_cost columns, and reservation_net_effective_cost shows the amortized cost after discounts. In Cost Explorer, select the amortized cost view to see Capacity Block costs allocated for the reservation.

Amortization for Capacity Blocks is available at no additional charge in all AWS Regions except the AWS GovCloud (US) Regions and the China Regions.
