COST OPTIMIZATION EXCEL DESCRIPTION

Cost Allocation & Chargeback Model - Professional Edition is an Excel template (XLSX) available for immediate download upon purchase.

Turn raw IT and shared-services spend into defensible unit costs, transparent chargebacks, and board-ready reporting.
This professional Activity-Based Costing (ABC) model allocates the fully-loaded cost of an IT or shared-services function down to the services it delivers. It follows the classic three-stage ABC methodology – Resource Pools β†’ Activities β†’ Cost Objects – and produces clean unit costs, an internal chargeback/showback report, a live rate card, and a real-time dashboard.
Unlike simple cost-spreading spreadsheets, this model is purpose-built for IT and shared services. It handles labor pools, cloud hosting, infrastructure, and overhead separately, then drives costs through measurable activity drivers (tickets, provisioning requests, migration projects, FinOps reviews, etc.) to the business units and clients that actually consume them.

Attach a measurable volume driver to each Activity β†’ unit costs calculate automatically.
Enter how many units each Business Unit / Client consumed β†’ chargeback amounts appear.
Set internal surcharge and external margin β†’ rate card and billing summary are generated.

All downstream reports, the Dashboard, and the Pricing Snapshot stay in sync.
