Service Costing for CA Intermediate Cost and Management Accounting
Service costing finds the cost of a service, not a product. You pick a suitable composite cost unit (like passenger-km or patient-day), classify costs as fixed, semi-variable or variable, total them, and divide by the units to get cost per unit. Then add profit or check fares and rates.
What this chapter covers
Service Costing applies the cost sheet idea to businesses that sell services: transport, hospitals, hotels, schools, power supply and similar. There is no stock of finished goods, and the output cannot be stored. So the main task is to choose a sensible unit of service and to group costs correctly around it.
The chapter has one method repeated in different settings. Choose the cost unit, classify costs, prepare a cost statement for the period, and compute cost per unit. Transport adds operating-cost heads and unit calculations like passenger-km. Hospitals and hotels add units like bed-day or room-day, plus charges for occupancy and profit.
This chapter links to other parts of the paper. It uses cost classification and cost sheet ideas from the early chapters, and fixed and variable behaviour from marginal costing. Pricing questions here also feed into decision-making thinking. It is a short, formula-light chapter, so it is a good place to secure marks.
Service Costing is among the more predictable chapters in the paper. The calculations are simple, but marks depend on choosing the right cost unit, using the right denominator and presenting a neat cost statement. A student who practises these three habits can score well in both MCQs and written questions. MCQs often test the cost unit or a quick per-unit figure, while written questions award step marks for classification, working notes and the final rate. Because the effort needed is low compared with the marks at stake, this chapter repays a short, focused study.
Service Costing: topics in the order to study them
- 1Introduction to Service CostingStart here to learn how services differ from products and why cost per unit of service is the aim.
- 2Cost Units and Cost Classification in Service SectorChoosing the correct unit and grouping costs is the base for every numerical that follows.
- 3Transport Service CostingIt is the most tested setting, and it teaches how to compute composite units like passenger-km.
- 4Hospital, Hotel and Other Service CostingStudy it last, as it reuses the same method with new units and cost heads.
How to prepare Service Costing
Treat this chapter as one method with a few settings. Learn the method first, then practise it in each setting until the layout is automatic.
- Read the features of services in your own words: intangibility, perishability, inseparability and variability. Be ready to state them in two or three lines.
- Make a list of services and their usual cost units, for example passenger-km, tonne-km, patient-day, room-day and bed-day. Revise it until you can recall it without looking.
- Learn how to classify costs into fixed, semi-variable and variable, and how to separate running costs from standing charges in a statement.
- Solve transport questions in a fixed layout: compute total units first, then list costs under standing and running heads, then divide to get cost per unit.
- Solve hospital and hotel questions the same way, taking care over occupancy, days in the period and any charge for profit on cost or on fare.
- Do a timed set of MCQs on cost units and per-unit calculations, then one written question where you show every working note.
- Keep a one-page sheet of cost units and layouts, and revise it a day before the exam.
Common mistakes in Service Costing
Using the wrong cost unit, such as passengers instead of passenger-km.
Fix: Underline the unit asked for. Then write the unit formula as the first line of your working.
Mixing up capacity and actual load for absolute and commercial units.
Fix: Absolute units use capacity × distance. Commercial units use actual load (or actual passengers) × distance. Use whichever the question asks for, and write the basis in your working note.
Forgetting the return journey when counting distance.
Fix: Check whether the trips are round trips and whether the load differs on the return. Write the distance and load for each leg.
Mixing fixed and running costs in one lump.
Fix: Group costs under standing charges, maintenance and running costs, and give a subtotal for each, as this is where step marks sit.
Using total days in the year when the facility ran for fewer days.
Fix: List the days available and the occupancy rate in a working note, then compute the occupied units.
Confusing profit on cost with profit on fare.
Fix: For profit on fare of x%, cost is (100 − x)% of fare. Divide cost by that percentage to get fare.
Last-day revision: Service Costing
- Service costing finds cost per unit of service, usually a composite unit.
- Services are intangible, perishable, inseparable and variable, and cannot be stored as stock.
- Absolute passenger-km = passenger capacity of the vehicle × distance. Commercial passenger-km = average (actual) passengers carried × distance.
- Absolute tonne-km = load capacity of the vehicle × distance. Commercial tonne-km = average (actual) load carried × distance.
- Use whichever basis the question asks for: capacity for absolute units, actual load for commercial units.
- Bed-day and room-day depend on the number of days the facility was available or occupied, so read the question carefully.
- Occupancy affects the units: use occupied days when cost is per occupied unit.
- Classify costs as fixed, semi-variable or variable before you total them.
- Cost per unit = total cost for the period ÷ total service units for the period.
- Profit added on cost is a percentage of cost; profit on fare is a percentage of fare. Read which one is asked.
- Show working notes for units and for cost totals, since they earn step marks.
- State the final rate with its unit, such as ₹ per passenger-km.

Service Costing: frequently asked questions
What is service costing in CA Intermediate?
It is the method of finding the cost of providing a service, such as a bus trip or a hospital stay. You pick a unit of service, total the costs for the period and divide by the units. It is used in Paper 4, Cost and Management Accounting.
Is Service Costing important for the MCQs?
Yes, it can be tested in MCQs. Typical questions ask for the right cost unit for a service or a quick per-unit calculation. MCQs carry 1 or 2 marks, have no negative marking and need no reasoning.
Which topic of Service Costing should I do first?
Start with the introduction and the cost unit and classification topic. Once you know how to pick units and group costs, transport, hospital and hotel problems follow the same pattern.
How do I score step marks in service costing answers?
Show a working note for total units, then a clear cost statement with fixed and running costs grouped. End with the cost per unit and state the unit. Even if one figure is wrong, the method earns marks.
