What is Job Costing? Objectives and Advantages

Job Costing Definition

Job costing is defined as a method of recording the costs of a manufacturing job, rather than process. With costing systems, a project manager or accountant can keep track of the cost of each job, maintaining data which is often more relevant to the operations of the business.

According to Eric Kohler___ “Job costing is a method of cost accounting whereby cost is compiled for a specific quantity of product, equipment, repair or other service that moves through the production process as a continuously identifiable unit, applicable material, labour, direct expenses and usually a calculated portion of the overhead being charged to job order”.Job Costing
