Accounting for Overhead Expenses

When quoting construction jobs, it’s important to consider not only direct costs such as materials and labor, but also indirect costs known as overhead expenses. These costs are not directly tied to a specific project but are necessary for running your construction business. Making sure to account for overhead expenses in your quotes will help ensure that you’re covering all of your costs and making a profit.

What are overhead expenses?

Overhead expenses are costs that are incurred as part of your regular business operations, but are not directly attributable to a specific project. They include expenses such as rent, utilities, insurance, office supplies, marketing, and administrative staff salaries. While these costs may not be tied to a specific job, they are essential for the smooth operation and growth of your construction business.

Calculating overhead costs

Calculating your overhead costs is an important step in accurately pricing your construction jobs. There are a few different methods you can use to calculate your overhead costs, depending on the size and complexity of your business. Here are two common methods:

  1. Fixed cost method: This method involves identifying your fixed overhead costs, which are the expenses that remain the same regardless of the volume of work. Examples of fixed overhead costs include rent, insurance premiums, and administrative salaries. You can calculate your fixed cost overhead rate by dividing your total fixed overhead costs by the total number of hours worked by your team in a given period.
  2. Activity-based costing method: This method involves identifying and allocating your overhead costs based on the activities that generate those costs. For example, if you have an office manager who spends 20% of their time on project-related tasks, you would allocate a portion of their salary and benefits to each project based on that percentage.

Incorporating overhead costs into your quotes

Once you have calculated your overhead costs, you’ll need to incorporate them into your quotes to ensure that you’re covering all of your expenses and making a profit. Here are a few common methods for including overhead costs:

  • Percentage markup: One common method is to calculate a percentage markup on your direct costs, which includes both materials and labor. This markup should be high enough to cover your overhead costs and allow for a reasonable profit margin. The percentage markup can vary depending on your business and industry, but a good rule of thumb is to aim for a 20-30% markup.
  • Separate line item: Another method is to include a separate line item in your quote for overhead expenses. This can help your clients understand the breakdown of costs and see that you are including all necessary expenses in your quote.
  • Hourly rate: If you prefer, you can also calculate your overhead costs on an hourly basis and include them as part of your labor rate. This can be especially useful if your projects vary in size and scope.


Accounting for overhead expenses is an important aspect of quoting construction jobs. By accurately calculating and including these costs in your quotes, you can ensure that you’re covering all of your expenses and making a profit. Whether you choose to use a percentage markup, separate line item, or hourly rate, make sure to communicate to your clients the value and professionalism that your construction business brings to each project.

Determining Profit Margin

Determining the profit margin is an important step in quoting construction jobs. It allows you to calculate the amount of profit you need to make to cover your costs and ensure a healthy return on investment. Here are some steps to help you determine the profit margin for your construction jobs:

1. Understand Your Costs

Before you can determine your profit margin, you need to have a clear understanding of your costs. This includes direct costs such as materials, labor, and equipment, as well as indirect costs like overhead expenses and administrative fees. Calculate all these costs to get an accurate picture of what it will take to complete the job.

2. Set a Target Profit Margin

Once you know your costs, you can set a target profit margin. This is the percentage of profit you want to make on top of your costs. Consider factors like market conditions, competition, and the complexity of the project when setting your profit margin. It should be reasonable and allow for a sufficient return on your investment.

3. Calculate the Markup

To determine the markup percentage, divide the target profit margin by 100 and add 1. For example, if your target profit margin is 20%, the markup would be 1.2. Multiply this markup by the total cost of the project to get the price you should quote to the client.

4. Review and Adjust

Once you have calculated the price, review it to ensure it covers all your costs and delivers the desired profit margin. If the price seems too high, you may need to adjust your profit margin or look for ways to optimize your costs. It’s important to strike a balance between a competitive price and a healthy profit margin.

5. Monitor and Track

After quoting the job, it’s important to monitor and track your actual costs and profits. This will help you assess the accuracy of your initial quote and make any necessary adjustments for future projects. Regularly reviewing your profit margins will ensure that you stay on top of your financial performance.

By following these steps, you can determine a fair and profitable margin for your construction jobs. Remember to regularly evaluate and adjust your profit margins to ensure sustainable business growth.

Presenting the Quote to the Client

After preparing a detailed quote for the construction job, it’s time to present it to the client. The way you present the quote can greatly impact the client’s perception of your professionalism and attention to detail. Here are some steps to effectively present the quote:
