What Is Job Costing? Accounting Definition, System & Examples

The costs pertaining to each job are collected and recorded with reference to the job number or production order number a job cost sheet or job cost card is opened for each job. Each job is identifiable from the stage of material till its completion and delivery. The following are the features of industries and firms where job costing is usually applied. The costing method has to be adapted to suit the specific features in an industry or a firm. Job costing (project-based accounting) is an essential tool to understand the profitability of individual jobs and make informed decisions regarding resource allocation and pricing strategies.

The company can then compare this cost per unit to the selling price to determine the project’s profitability. The manufacturing overhead costs, which include rent, utilities, and equipment depreciation, are estimated to be $150,000. Then, by comparing the job cost to the estimated revenue generated by the project, you can determine the job’s profitability. The profit or loss on the job is calculated by comparing the total cost to the selling price. Job costing provides a clear view of all the direct and indirect costs and how they affect the budget.

Cost Control

The predetermined overhead rate is a calculation that estimates overhead costs per unit of activity. The calculation requires an estimated overhead amount and an estimate on the total activity you’re planning to use as a barometer. It involves calculating direct labor, material costs, and applying overhead to understand total job costs and profit. The job costing system must track the cost of the labor used on a job.

Separate cost sheet is prepared for each job to ascertain its cost and profit. The formula is entirely based on estimates, so the actual costs may vary from the estimated amount. The direct material cost for this job would include the cost of flour, sugar, butter, eggs, and other ingredients required to make the cake.

Material

CIMA definition of Job costing is “It is a form of specific order costing in which costs are attributed to individual jobs”. Thus, each ‘Job’ is treated as a distinct cost unit for which costs are accumulated. In the construction industry, for example, numerous workers and supplies are involved in each project, making detecting overspending challenging. Tracking construction expenses on a project basis allows managers to create more accurate forecasts and identify unexpected costs that could impact profits. A costing sheet is a comprehensive list of all expenditures for a project. It leverages unit pricing and uses historical data to facilitate comparisons.

Calculating Labor Costs

In process costing, costs are recorded for each stage of production and then averaged over the total number of products to determine the cost per unit. The process starts with an incoming customer order (CO) for the required items. An MRP system tracks the materials and labor for the production of the items. Manufacturing overhead is then allocated to the job, usually using a predetermined overhead rate (per labor hours or machine hours).

Additionally, if the actual cost changes by the end of the job, a clear job costing breakdown can help you explain to the customer why the final cost varied. When you break down your expenses, income, and overhead costs by job, you should better understand how, where, and why you can cut costs. You can also make sure you’re charging customers the right amount for each job. After all, if you’re charging only for hours worked without accounting for materials and overhead costs, you aren’t making money; you’re losing it. While deciding job costing vs process costing, If you need to track costs for individual projects with pinpoint accuracy, choose job costing.

• In these cases, businesses use either a rough estimate or a flat amount to approximate the costs of the job.

• Manufacturing overhead is then allocated to the job, usually using a predetermined overhead rate (per labor hours or machine hours).
• They usually work as a small team for each job code and the supervisor is responsible for their job allocation.
• The industries which manufacture articles or products or render services against specific orders, use the Job Costing method for ascertaining the cost per job or service.
• If they estimate their total overhead costs to be $200,000 and their total direct labor hours to be 5,000, their predetermined overhead rate would be $40 per direct labor hour.

This means setting a flat, steady percentage that is used to calculate the applied overhead across all jobs. It’s best to track the exact costs, but some may be difficult to track like the gas used to take a vehicle to and from the job site. In these cases, businesses use either a rough estimate or a flat amount to approximate the costs of the job. Any variance needs to investigate and make a change for the next job budget if necessary. It also has a huge impact on management decisions on setting up the price as well. Most companies use labor or machine hour as the cost driver for allocating costs to each job.

• An MRP system tracks the materials and labor for the production of the items.
• On completion of the job, add overhead charges to determine total expenditure.
• Retail Companies – It takes a lot more than having the product on hand to run a retail business.
• Like other systems, the products pass through various processes and workstations.
• If any surplus material is returned from the job to the stores, the job account is given due credit for the value of the same.
• It is maintained as per the allotted job number specifying relevant costs and elements.

Production volume, the mode of production, and the complexity of the product can all make costing a veritable challenge. A large product line further exacerbates this, making sacrifices in accuracy often inevitable when relying on manual methods. Job costing is widely used in all kinds of companies and industries that do business one specific project at a time. A common example is the construction industry, where a construction project is one cost article, albeit a complex one.
