What is operating costing?• Operating costing method is one designed to ascertain
and control the costs of the undertakings which do not produce products but which render services
• Also known as service costing• Operation costing is the cost of rendering services• It is the cost of producing and maintaining a service• Industries using operating costing do not produce
tangible poducts ; but useful service is rendered; for eg-transport services, utility services like hospitals, canteens etc, distribution services like supply of electricity, gas etc.
Service CostingService or operating cost is the cost of providing service. The
term service costing is applied to describe the system used to find the cost of performing a service such as transport, gas or electricity.
• Services rendered to customers are of unique and standardised type
• Distinction between fixed cost and variable cost is of special importance as the scale of operations considerably affects the cost per unit of service rendered
• A large chunk of total capital invested in fixed assets and relatively less working capital is required
• The method of costing is different from that used in connection with production and difference lies mainly in the manner of accumulating the cost data and finally in its allocation to cost units
Cost Unit-Selection of cost unit is different in operating costing
SNONAME OF THE UNDERTAKING
COST UNIT
1 Passenger transport Passenger km/mile2 Goods transport Ton mile/km3 Hotel lodging Per bed, per person, per day4
HospitalsPer bed, per day, per operations, per patient, per test, per x-ray etc.
5 Electricity Kilowatt-hour6 Boiler house Kilograms of streams supplied7 Cinema theatre Man-show8 Canteens Meals served, cups of tea sold9 Gas works Per 100 cubic ft produced10 Water supply Per 1000 gallons
Classification of Costs1.Fixed costs or standing charges2.Semi-variable costs or manufacturing charges3.Variable costs or operating-running charges
CharacteristicsThese undertakings render unique services to their
customersThey invest large proportion of their capital in fixed
assetsThe requirement of working capital comparatively is lessThe operating cost is divided into fixed and variable and
they are of utmost importance
TRANSPORT COSTINGObjective of Transport CostingAscertaining the rates of carriage of good/passengers on the basis of operating costsAscertaining the price at which the vehicle should be hired outComparing the cost of using own motor vehicles and that of using alternative forms
of transportAscertaining what should be charged against the departments , or others, using the
service
Cost Unit
1. Absolute (Weighted Average) tonnes-kms: The sum total of tonnes-kms., arrived at by multiplying various distances by respective load quantities carried
Absolute Tonne Km = Dist1 x Qty1 + Dist2 x Qty2
2. Commercial (Simple Average) tonnes-kms : Arrived at by multiplying total distance kms., by average load quantity
Commercial Tonne Km = Total Dist x Average Qty
EXAMPLE Question:
A lorry starts with a load of 20 tonnes of goods from station A. It unloads 8 tonnes at station B and rest of goods at station C. It reaches back directly to station A after getting reloaded with 16 tonnes of goods at station C. The distance between A to B, B to C and then from C to A are 80 kms., 120 kms., and 160 kms., respectively. Compute ‘Absolute tonnes-kms.,’ and ‘Commercial tonnes-kms.
Solution:
Absolute tonnes-kms. = 20 tonnes × 80 kms + 12 tonnes × 120 kms + 16 tonnes × 160 kms. = 5,600 tonnes-kms
Commercial tonnes-kms. = Average load × total kilometres travelled 16 tonnes( i.e. (20+12+16)/3 ) × 360 kms. = 5,760 tonnes-kms
PREPARATION OF COST SHEET UNDER TRANSPORT COSTING Costs are usually accumulated for a specified period viz., a month, a quarter, or a year.
All of the accumulated costs should be classified under the following thread
1. Fixed Costs or Standing Charges(license Fee And Insurance,, Administrative Expenses, Depreciation and Tax ,Wages Of drivers, conductors and cleaners)
2. Variable Costs or Running Charges( Fuel, Oil, grease/Lubricants Etc.)
3. Semi-variable Costs or Maintenance Costs.(Supervision Salary, Repairs and Maintenance, Garage Costs, Tubes and Tyres)
Note : In the absence of information about semi-variable costs, the costs may be shown
under two heads only, i.e., fixed and variableDepreciation - Depreciation if related to effluxion of time, may be treated as
fixed. If it is related to the activity level, it may be treated as variable Interest - If information about interest is explicitly given, it may be treated as
fixed cost
EXAMPLEQuestion:- The Union Transport Company has been given a twenty kilometer
long route to ply a bus. The bus costs the company 1,00,000. It has been insured at 3% per annum. The annual road tax amounts to 2,000. Garage rent is 400 per month. Annual repair is estimated to cost 2,360 and the bus is likely to last for five year. The salaries of the driver and the conductor are 600 and 200 per month respectively in addition to 10% of the takings as commission to be shared equally by them. The manager’s salary is `1,400 per month and stationery will cost 100 per month. Petrol and oil will cost 50 per 100 kilometres. The bus will make three round trips per day carrying on an average 40 passengers in each trip. Assuming 15% profit on takings and that the bus will ply on an average 25 days in a month, prepare operating cost statement on a full year basis and also calculate the bus fare to be charged from each passenger per kilometre.
SOLUTION Union Transport Company Statement showing
operating cost of the bus per annum: A – Standing Charges: • Manager’s salary (1,400 * 12) = 16,800 • Driver’s salary (600 * 12) = 7,200 • Conductor’s salary (200 * 12) = 2,400 • Road tax = 2,000 • Insurance (3% of 1,00,000) = 3,000 • Garage rent (400 * 12) = 4,800 • Stationery (100 * 12) = 1,200 • Depreciation (1,00,000/5 years) = 20,000
CONTINUED…
B – Maintenance Costs – Repairs 2,360 C – Running charges: • Petrol and oil (36,000 km. * 50)/100= 18,000 • Total costs (A+B+C) 77,760 • Add: 10% of takings for commission of • driver and conductor • 15% Profit – desired on takings • 25% on total takings = 25,920(77760*25/75)• Total Revenue = 1,03,680(77760*100/75)
CONTINUED…
Calculation of total distance covered:
(20 km. * 2 * 3 * 25 * 12) = 36,000 km per annum
Calculation of bus fare to be charged:
Effective passenger – kilometers: (2 * 20 km * 3 trips * 40 passengers * 25 days * 12 months) = 14,40,000
Rate to be charged per km from each passenger: = 1,03,680 /14,40,000 = 0.072
POWER HOUSE/BOILER HOUSECOSTING
The costs may be considered under the following headings:
• SUPERVISION-Wages of foremen, and salary of work engineers.
• LABOUR-Wages of coal handlers, stokers and ash removers.
• MAINTENANCE-furnace repairs, renewal of the fire bars, replacement of
fire irons etc.
• INDIRECT MATERIALS-service materials and small tools.
• FUEL-coal or oil and its carriage, handling and storage.
• WATER-cost of supply , purification and softening.
• FIXED OVERHEAD-Rent ,rates , depreciation, insurance and interest on
capital.
BOILER HOUSE• Prepare a cost sheet showing the cost of generation the cost of steam per
unit.• Total units of steam generated: 1,00,000 units.
• Normal consumption of coal for generation of steam is 2 Kg for every unit of steam generated @Rs.200 per quintal.
• Interest on capital to be included in costs @ 10% per year.

• Cost of 1 metric tonne i.e 2204.62 lbs of coal =
Rs.33.06
• Therefore cost of 1.5 lbs=33.06/2,205 *1.5 =
Rs.2.25(approax)
• Cost of coal for generating 15,00,000 units of power
=(33.06*1.5*15,00,000)/2,205 = Rs.33,734(Approax)
