Construction Budget Template

Next, set up the Job Cost Budget sheet for your current or upcoming projects. Enter the contract value and your estimated costs by category — materials, direct labor, subcontractors, equipment rental, and permits. As costs come in during the project, update the actual figures. The sheet will show you cost variance by category in real time, so you know immediately when materials are running over estimate or when a subcontractor change order is eating into your margin. Construction profit lives and dies in job cost control, and this is where that work happens.

A well-structured construction budget addresses both layers separately. On the overhead side, the key number is your overhead rate — total overhead as a percentage of revenue. For small contractors, this typically runs 20–25%. That number needs to be built into every bid you submit; if you're marking up direct costs by 10% but your overhead rate is 22%, you're losing money on every job before profit is even considered. On the job cost side, the standard categories — materials, direct labor, subcontractors, and equipment — need to be broken out individually because they behave differently. Materials and subcontractor costs can be locked in early; labor is where overruns usually appear.
