What overhead rate is: Your overhead rate tells you how much indirect cost you incur for every unit of your allocation base. If your overhead is $50,000 and you have 1,000 labor hours, each hour carries $50 of overhead. This rate is added to direct costs when pricing jobs.
Why it matters: Without an overhead rate, you are guessing at job profitability. A job that looks profitable on direct costs alone may lose money once you factor in rent, utilities, insurance, and admin salaries. The overhead rate makes the invisible cost visible.
Choosing your allocation base: Labor hours work for service businesses (agencies, consultancies). Machine hours work for manufacturing. Revenue works for retail. The base should correlate with overhead — if more labor hours drive more overhead, use labor hours. Pick the simplest base that tells the truth.
Calculating total overhead: Add rent, utilities, insurance, depreciation, admin salaries, office supplies, software subscriptions, and any other cost that is not directly tied to a specific job. For a Denver consulting firm, this might include $2,000/month rent, $500/month utilities, $300/month software, and a $4,000/month admin salary = $6,800/month or $81,600/year.
Using the rate for pricing: When quoting a job, add (overhead rate × estimated hours) to your direct labor and material costs. If direct labor is $3,000 and overhead adds $1,500, your cost basis is $4,500. Apply your desired margin on top to set the client price.
Where it is used
A construction firm in Austin pricing a $50,000 job with 1,000 labor hours; a design studio in Chicago billing clients at overhead-adjusted rates; a manufacturing plant in Miami calculating machine-hour rates; a consulting firm in Denver setting per-diem billing; a repair shop in Seattle quoting service jobs; an agency in New York determining true cost per employee.

Frequently Asked Questions
- What should I include in overhead?
- Include all indirect costs: rent, utilities, insurance, depreciation, admin salaries, office supplies, software, and marketing. Exclude direct costs like materials and direct labor tied to specific jobs.
- How do I choose the right allocation base?
- Choose the base that best correlates with overhead consumption. Labor hours for service firms, machine hours for manufacturing, and square footage for facilities-heavy operations. Start simple and refine over time.
- Should overhead rate change over time?
- Yes — recalculate quarterly or annually. As your business grows, overhead costs shift. A firm that doubles headcount may see overhead rate drop if revenue grows faster than indirect costs.
- What is a good overhead rate?
- It varies by industry. Service firms typically run 50–100% of direct labor cost. Manufacturing runs 30–80%. The goal is to price jobs so the overhead rate is fully covered, not to minimize it.
- Can I use overhead rate for break-even analysis?
- Yes — the overhead rate tells you the minimum hourly charge needed to cover indirect costs. If your overhead rate is $50/hr and direct labor is $75/hr, you need to bill at least $125/hr before profit.
- How does this differ from markup?
- Overhead rate is a cost allocation — it tells you what overhead costs per unit. Markup is a pricing decision — it adds profit on top of cost. Apply markup after calculating overhead-adjusted cost.
