What is a typical overhead rate for construction?

Overhead rates typically range from 20-35% of direct costs for residential contractors. Commercial general contractors often run 15-25%. Specialty subcontractors may range from 10-30% depending on their business model and scale.

Should owner salary be included in overhead?

If the owner works in the field, a portion of their salary should be allocated to direct costs based on field time. The administrative portion belongs in overhead. If the owner is purely management, their entire salary is overhead.

How often should I recalculate my overhead rate?

Recalculate at least annually with actual financial data. Update mid-year if you make significant changes like hiring office staff, moving to a larger shop, or adding vehicles.

What This Calculator Does

This calculator determines your construction company overhead rate as a percentage of direct job costs. It breaks down overhead expenses by category, calculates monthly overhead burden, and shows the minimum revenue needed to cover both direct costs and overhead before generating any profit.

The Formula

Overhead Rate = (Total Overhead / Total Direct Costs) x 100

Overhead includes all business expenses that are not directly tied to a specific job: office rent, insurance, vehicle costs, administrative salaries, utilities, and other fixed expenses. The overhead rate expresses these costs as a percentage of your direct job costs (materials, labor, subcontractors, equipment rental). A 25% overhead rate means you spend $0.25 in overhead for every $1.00 in direct costs.

Step-by-Step Example

Enter annual direct costs

Total of all materials, field labor, subcontractors, and job-specific equipment across all jobs. Example: $500,000.

Itemize overhead expenses

Enter annual costs for office rent, insurance, vehicles, utilities, admin salaries, and other overhead. Example: $156,000 total.

Enter annual revenue

Your total revenue to see overhead as a percentage of revenue as well. Example: $750,000.

Analyze your overhead rate

An overhead rate of 31.2% means every job must recover $0.31 in overhead per dollar of direct cost before any profit is earned.

Break-Even Analysis

Calculate the minimum annual revenue needed to cover all direct costs plus overhead before earning any profit.

Common Mistakes to Avoid

Not including all overhead items. Common overlooked costs include accounting fees, software subscriptions, warranty callbacks, licensing, and continuing education.
Using last year overhead rate without adjusting for growth. Adding employees, vehicles, or office space changes your overhead significantly.
Applying the same overhead rate to labor-heavy and material-heavy jobs. Some contractors allocate overhead based on labor hours for more accurate job costing.
Confusing overhead rate (based on direct costs) with overhead as a percentage of revenue. Both metrics are useful but measure different things.

Frequently Asked Questions

Accuracy and Disclaimer

Overhead rates vary significantly by company size, trade, region, and business model. Industry benchmarks are guidelines, not targets. Work with your accountant to accurately categorize expenses and calculate your specific overhead rate for bid pricing.
