Job Costing: Definition and Meaning

Definition

Job costing is a method of assigning and tracking costs by individual job, project, contract, or customer engagement.

Why It Matters

For construction companies, job costing can help management understand project profitability, compare actual costs with estimates, identify cost overruns, improve future estimating, and support work-in-progress reporting. It may include direct labor, materials, subcontractors, equipment, permits, and other costs assigned to a specific project.

Job costing is most useful when information is timely, codes are applied consistently, and project-management and accounting systems communicate effectively.

Example

A contractor assigns labor hours, material purchases, subcontractor invoices, and equipment costs to a specific project to evaluate that job’s profitability.
