Overhead Rate Benchmarks by Business Size
Your overhead rate depends on how much fixed cost your business carries relative to the jobs you run. A solo operator working out of a truck will always have a lower rate than a company with an office, a shop, and admin staff. The table below shows typical ranges based on NAHB data and field experience.
| Business Type | Typical Overhead Rate | Common Overhead Items |
|---|---|---|
| Solo operator | 10% - 20% | Insurance, phone, fuel, basic tools |
| Small crew (2-5) | 20% - 35% | Vehicles, workers comp, equipment, marketing |
| Mid-size company (6-20) | 30% - 50% | Office rent, admin staff, fleet, software, accounting |
| Large contractor (20+) | 40% - 60% | Multiple offices, project managers, HR, legal, bonding |
If your calculated rate falls well outside the range for your business size, review your biggest expense categories. A rate that is too low usually means you are missing costs (insurance, depreciation, or your own non-billable time). A rate that is too high may signal inefficiency or low job volume spreading fixed costs too thin.
How to Use This Calculator
Enter Your Annual Overhead Costs
Add up all business expenses that are not tied to a specific job: insurance, rent, vehicle costs, tools, marketing, phone, and admin. This is your total annual overhead.
Enter Your Annual Direct Costs
Total all labor and material costs you spent on jobs last year. Direct costs are expenses you can tie to a specific project. If you are new, estimate based on your expected job volume.
Set Your Profit Margin
Choose a profit margin to add on top of your costs. Most contractors target 15-25%. This margin covers business growth, equipment replacement, and a buffer for slow months.
Price a Specific Job (Optional)
Enter the direct cost of any job to see the exact overhead amount, profit, and final bid price. Use this to build accurate bids that cover all your costs plus profit.
Contractor Overhead Rate Formulas
Overhead Rate = (Annual Overhead / Annual Direct Costs) x 100
Break-even Revenue = Direct Costs + Overhead
Required Revenue = Break-even Revenue / (1 - Profit% / 100)
Job Bid Price = (Job Direct Cost + Job Overhead) / (1 - Profit% / 100)Where:
- Annual Overhead
- = All recurring business expenses not tied to a specific job
- Annual Direct Costs
- = Total labor and material costs spent on jobs per year
- Profit%
- = Desired profit margin on top of total costs (typically 15-25%)
- Job Direct Cost
- = Labor + materials for one specific job

Frequently Asked Questions
What is a contractor overhead rate?
Your overhead rate is the percentage of your direct costs that goes toward covering business expenses not tied to any single job. It is calculated by dividing your annual overhead by your annual direct costs and multiplying by 100.
For example, if you spend $50,000 per year on overhead and $200,000 on direct job costs, your overhead rate is 25%. That means for every $1 you spend on labor and materials for a job, you need to add $0.25 to cover overhead.
What is the difference between overhead rate and markup?
Overhead rate measures overhead as a percentage of your direct costs (labor + materials). It tells you how much overhead you need to recover per dollar of direct cost.
Markup is the percentage you add on top of total cost (direct costs + overhead) to set a selling price. Markup includes both overhead recovery and profit. A markup calculator helps you set the final selling price, while the overhead rate helps you understand and control your cost structure.
What is a typical overhead rate for contractors?
Most contractors operate with an overhead rate between 20% and 35% of direct costs. Solo operators or small crews with low fixed expenses may run as low as 15%. Larger companies with office space, vehicles, and admin staff often land between 30-50%.
According to NAHB data, the average overhead and profit (O&P) markup in residential construction is about 25%. If your rate is well above 35%, look at your biggest overhead categories for savings. If it is under 15%, double-check that you are not missing expenses like insurance, vehicle depreciation, or tool replacement.
How do I lower my overhead rate?
You can lower your overhead rate two ways: reduce overhead expenses or increase direct cost volume (take on more work). Common ways to cut overhead include bundling insurance policies, sharing shop or office space, switching to lower-cost software, and reducing advertising spend on channels that do not generate leads. Increasing your job volume spreads fixed overhead across more projects, which drops the rate even if total overhead stays the same.
Should I include my salary in overhead or direct costs?
It depends on your role. If you work on job sites, the hours you spend on jobs are a direct cost. Time spent on bidding, admin, scheduling, bookkeeping, and driving between jobs is overhead. Many owner-operators split their time roughly 60% direct / 40% overhead. If you are not sure, track your time for a month and categorize it.
