Percentage of Unallocated Shared CSP Cloud Cost
Definition
This measurement refers to expenses that cannot be directly attributed to a specific project, team, or department within an organization. An organization should select a cost model to distribute shared costs. Example shared cost models include, shared costs are evenly chargedback across all cloud consumers, proportionally charged back based on cloud consumption, or charged back based on another metric used to determine allocation. The goal is to reduce the percent of shared costs not being chargedback overtime.
Formula, as published

How to measure it
Shared costs are the ones no single team owns: support plans, shared networking, platform clusters, security tooling. They need a split rule (even, fixed percentages, or proportional to usage or spend) before they can be allocated.
Pair it with an apportionment check: the apportioned amounts should add back to the shared total.
