CAS-13: Cost of Service Cost Centre
The canteen and the store never sew a uniform, yet the tailors can’t work without them. Who pays for them, and how much?
What you will learn in CAS-13
- What a service cost centre is, and what its cost includes (§§4.13, 5)
- Sharing service cost fairly (§6)
- Normal capacity and stand-by services (§5.7)
- Services supplied to other units and outsiders (§§5.2.5–5.2.7)
Chapters
- Who pays for the canteen? · Departments that help, but never make a uniform (§§4.13, 5.1, 5.2.2, 5.3, 5.4, 5.10)
- Sharing the canteen fairly · Share each service by how much each department uses it (§§6.1–6.3, 7, 8)
- The idle van and tea for the neighbours · A half-used service, and a service sold to others (§§5.2.5–5.2.7, 5.7)
- Spot the mistakes in the canteen account · Use everything from this lesson (§§5.4, 5.9, 5.10, 6.3)
Key terms
- Service cost centre (§§4.13, 5.1, 5.2.2, 5.3, 5.4, 5.10): A department that gives support services to the rest of the business, like a canteen, store or van. Each one is costed separately: its materials, people, utilities and overheads, less money recovered. Interest and pretend costs stay out.
- Sharing service cost (§§6.1–6.3, 7, 8): Put the service cost straight on whoever used it where you can. Otherwise share it on a fair measure of use, applied the same way each time. Show each important service as its own line and say how it was shared.
Common questions
How is a service cost centre’s cost shared?
By traceability where possible, otherwise on logical usage parameters that are equitable, reasonable and consistent (paras 6.1–6.3).
On what capacity is service cost worked out?
Normal capacity or actual capacity, whichever is higher; unabsorbed cost is abnormal (para 5.7).
