Definition
IT cost allocation is the process of distributing technology costs — cloud, SaaS, AI, shared platforms, telecoms, and labor — to the business units, products, or services that benefit from them, using agreed rules and metadata.
Why it matters
When IT spend stays centralized, no product owner optimizes consumption. Allocation makes spend visible on business P&Ls and enables showback, chargeback, and credible planning cycles.
Related Terms
Cloud cost allocation
Attributing cloud spend to teams, products, or environments using tags, accounts, and policies — the basis for showback and chargeback.
Showback
A cost transparency practice that reports technology costs to business units without directly charging them for consumption.
Chargeback
The accountability model — technology spend is debited to the consuming team's budget and P&L, not held centrally by IT.
