How Overhead Allocation Affects Construction Job Costing and Profitability

Writer: Cost Construction Accounting Cost Construction Accounting

Maintaining control of spending is absolutely vital while running a building company. Many builders concentrate on direct expenses, such as labor and supplies, but they sometimes ignore a major consideration—overhead allocation. The financial success of a project can be either made or broken depending on how overhead expenses affect building job costing and general profitability. 

Overhead Allocation

What is Overhead Allocation?

Expenses supporting the company but not directly related to a specific project are known as overhead costs. These cover rent, office pay, insurance, equipment upkeep, even utilities. These costs must be distributed among several jobs since they do not fit only one project; this is known as overhead allocation.

Should improper overhead allocation be done, your projects may underprice themselves, resulting in profit losses, or overpriced them, so reducing the competitiveness of your bids.

Why is Overhead Allocation Important in Construction?

Many contractors don't correctly account for overhead costs, which causes them to lose money they didn't expect to. If you don't account for overhead costs, you'll get inaccurate job costing reports, which will hurt your ability to make money in building.

This is why good allocation is important:

  • It helps figure out how much each job really costs.

  • It keeps prices from being too low, which can cause losses.

  • It makes sure that the profit margins are determined correctly.

  • It helps with setting prices and buying strategically.

How Overhead Allocation Affects Job Costing

In construction, job costing is the process of tracking the costs associated with a specific project. This includes direct costs like labor, materials, and subcontractor fees, as well as overhead costs. How you allocate overhead can significantly impact the accuracy of your job costing and, ultimately, your project profitability.

Direct vs. Indirect Costs

It's crucial to distinguish between direct and indirect costs.

  • Direct costs are directly related to the production or completion of a project. For example, material and labor costs are direct costs because they are directly involved in the project's construction.

  • Indirect costs (overhead costs) are not directly related to the construction process but are required for commercial operations. Examples include office rent, utility bills, and administrative wages.

Allocating overhead expenditures effectively to each project guarantees that you have an accurate understanding of your profit margin for each work. If overhead is not appropriately allocated, job costs may be artificially low, making the project appear more profitable than it is.

Methods of Overhead Allocation

There are several ways to allocate overhead costs in construction, and the method you choose will depend on your business needs and structure. Here are some common methods:

1. Percentage of Direct Costs

This method applies overhead as a percentage of direct costs, such as labor and materials. For example, if direct costs total $100,000 and your overhead rate is 15%, you allocate $15,000 in overhead expenses to the project.

Pros: Simple to use

Cons: Can be inaccurate if projects have varying labor/material ratios

2. Labor Hour Method

Allocating overhead based on labor hours involves dividing total overhead by total labor hours worked. If your annual overhead expenses are $500,000 and your team logs 10,000 hours, the overhead rate is $50 per labor hour.

Pros: Works well for labor-intensive businessesCons: May not be suitable for material-heavy projects

3. Revenue-Based Allocation

Some contractors allocate overhead costs based on a percentage of total revenue. If your annual revenue is $5 million and overhead expenses are $500,000, you apply a 10% overhead rate to each job.

Pros: Ideal for companies with stable profit marginsCons: May not reflect actual job costs accurately

4. Activity-Based Costing (ABC)

This advanced method assigns overhead costs based on specific business activities, such as equipment usage or project management time.

Pros: Most precise methodCons: Requires detailed tracking

The Impact on Construction Profitability

Proper overhead allocation can have a significant impact on your construction profitability. Here's how:

1. Accurate Profit Margin Calculation

By appropriately assigning overhead, you receive a true view of the expenses associated with executing a project. This enables you to compute more accurate profit margins for each job. Without correct overhead allocation, your profit margins may appear bigger than they actually are, resulting in poor decision-making. 

2. Better Budgeting and Cost Control

When you understand how to correctly distribute overhead costs, you can build more precise construction budgets and predictions. This helps to prevent cost overruns by preparing you to successfully manage both direct and indirect costs.

3. Improved Decision Making

When you properly divide up your fees, you can see which projects make you the most money and which ones might need price changes or tighter cost control. You can make better business choices and change your plans for projects that will make you more money now that you know these things.
