Cost means “the price paid for something”

Cost ascertainment is computation of actual costs incurred

Units of services such as passenger miles, consulting hours, room per day, bed per day

Methods of costing

It refers to the techniques and processes employed in the ascertainment of costs

Choice of the method depends upon the type and nature of manufacturing activity

Types: Broadly,

Job costing or job order costing

Process Costing

Other methods are variations of one of these methods.

Methods of costing - Types

Job Order Costing – Applies where work is undertaken to customers special requirements.

Contract Costing or Terminal Costing: It is same as Job order costing; however, job is small and contract is big contract. Contract is of long duration and may continue for more than a financial year.

Batch costing: Cost of a batch or group of identical products is ascertained; each batch of products is a cost unit for which costs are ascertained.

Methods of costing –Types….. Process Costing – Applies to a context where there is a continuous process. Costs are accumulated for each process. And then total cost of a process is divided by the number of units produced to arrive at cost per unit.

Operations Costing: Involves cost ascertainment for each operation.

Operating or services costing: It is applied to services; cost units are passenger –kilometer, room per day, bed per day.

Methods of costing –Types…..

Multiple or composite costing – Application of more than one method of costing in respect of the same product. Used in industries where a number of components are separately manufactured and then assembled into a final product.

Single, output or unit costing: Applied to a context where output produced are identical, the cost per unit is found by dividing the total cost by the number of units produced. E.g. Steel output is identical but differentiated by grades.

Techniques of costing –Types….. Standard costing – Standard cost is

predetermined as target of performance and actual performance is measured against the standard.

Budgetary control: By comparing actual with planned / budgeted performance

Marginal costing: Only variable cost is allocated to individual cost centers or cost units

Techniques of costing –Types….. Total Absorption costing – Both fixed and variable

costs are charged to products.

Uniform Costing: It is not a technique but a situation wherein several undertakings use the same costing principle and practices.
