Job costing is an essential part of a business’s bottom line, especially for construction companies. Construction projects have many moving pieces and job costs can quickly escalate. Job costing for construction is designed to make accurate bids and turn a profit.

The construction business is known for skyrocketing job costs. Many times, original job costs will start to change, getting in the way of a completed job. Read on for more information about what construction job costing entails, estimated costs, and job costing software.

What is construction job costing?

A construction company will use job costing as a way to track, assign, and estimate project expenses on a project-by-project basis. Typically, construction job costing will estimate two different project costs: indirect costs and direct costs. These include labor hours, materials, equipment and other overhead costs.

Process Costing vs Job Costing

Construction job costing is a substitute for process costing. With process costing, the idea is the same, but the basics are different. Process costing calls on prior knowledge to make a determination of upcoming project costs. For example, if a large project costs the company $2,000, it can be assumed something half the size would be $1,000.

In the construction industry such an assumption cannot exist. Labor, materials, and equipment are broken down quite differently and a job cost is more accurate. As an example, say the use of equipment for either large or small projects will always cost $1,000—there is no use in taking on a project which pays less.

According to Inside Advisor Pro, this approach ensures that contractors can effectively allocate resources and make informed decisions about the projects they undertake, ultimately leading to increased profitability and long-term success.

How to calculate construction job costs

Breaking down job expenses into specific categories is the first step to accomplishing correct job costing. Let’s take a look at the example below.

Construction Job Costing

Example of Construction Job Costing

Though the above information is useful, construction job costing should be as detailed as possible. A further breakdown of the labor costs, material costs, and equipment costs provides more accurate job cost reports.

With a more detailed budget in hand, project managers can better prepare for a construction project, track progress, and stay within the projected costs. Calculating and tracking the total cost will help the company keep a healthy cash flow and allow for future jobs.

How to estimate project expenses: Breaking down the project

Job costing starts with breaking down the expected costs. Begin with each of the main phases of the project by reviewing the tasks required to finish the work. Construction companies will implement a cost code system to keep all of this organized. These then get separated out into three main expense types.

Labor costs

Thousands of dollars are lost every year by companies in the construction industry because of labor costs. Inaccurate reporting, mistakes during payroll, and scheduling issues all contribute toward rising costs and are notoriously hard to predict during the job costing process.

Material costs

Materials costs can be broken down into indirect materials and direct materials cost. Direct costs include items such as wood, concrete, and steel. Indirect costs include items such as nails or screws. To calculate an accurate project budget, it’s best to estimate the job cost per project, rather than using information from the past. Allow room for the cost to grow by as much as 10% to 20%.

Equipment costs

Equipment costs are some of the most straightforward with some room for a company to save. Rather than purchasing equipment, leasing might prove the best route, and vice versa. More expensive equipment or construction software could save money down the road in higher productivity and less overtime.

How to improve construction job costing

Accurate job costing starts with construction accounting software. A well-rounded accounting software will help track costs, making the entire job costing process easier and more accurate.

Time tracking

Implement an automated time-tracking system since manual time cards are often inaccurate.

Cost codes

Review cost codes for pricing and expensing to ensure there is proper alignment assisting with automated billing.

Monitor billing

Depending on the contract, a company could bill customers for construction costs, which need to be monitored closely for accuracy.

Frequently asked questions

What is the difference between process costing and construction job costing?

Construction job costing is the most accurate job costing process. Process costing uses data from past projects to determine potential job costs for a current construction job. A construction company should use construction job costing because it will use current data based on the materials, labor, and equipment needed to complete the project in order to determine the job cost.

What are the benefits of job costing?

Job costing is the key to maintaining cash flow. Construction jobs have many moving pieces causing costs, prices, and budgets to skyrocket. An accurate job costing process provides a target budget, allowing for various overhead and unexpected costs along the way without breaking the bank.
