What is a good profit margin for a service business?

Most field service companies aim for a 15–25% net profit margin. According to IBIS World industry reports, the average profit margin for plumbing services is around 11%, and for HVAC contractors roughly 10–15%. A 20% margin is a solid starting point that covers unexpected job costs and allows for business growth. If your pricing consistently leaves you below 10%, you are likely not accounting for all your overhead.

What is the difference between markup and margin?

Markup is the percentage added to your cost to reach a selling price. Margin is the percentage of the final selling price that is profit. For example, a 25% markup on a $400 cost results in a $500 price, which is only a 20% margin. A survey by Contractor Magazine found that confusing markup with margin is one of the top 3 pricing mistakes that cost contractors thousands in lost profit each year.

Should I include overhead in my service price?

Yes. If you only price for labor and materials, you are paying your overhead out of what you think is profit. Insurance, rent, vehicle costs, and software all need to be baked into every job price.

How do I calculate overhead per job?

Add up all monthly business costs (excluding direct labor and materials). Divide that total by the number of billable hours your team works in a month to get an hourly overhead rate. Then multiply by the duration of the specific job.

How often should I update my service prices?

Review your prices at least twice a year. Material costs, fuel prices, insurance rates, and wages all change. If your costs went up but your prices did not, your profit margin is shrinking without you noticing.

How to price a service job

Pricing a job too low means you work harder for less, while pricing it too high means losing the bid. The right price covers every dollar you spend and leaves a profit that makes the work worth doing. This calculator walks you through the full cost-plus pricing formula that successful contractors use.

Here is what the calculator accounts for:

Labor cost — Number of workers, hours on the job, and their loaded hourly pay (including taxes and benefits).
Material cost — Parts, supplies, and anything purchased specifically for this job.
Overhead expenses — Your share of fixed costs like rent, insurance, vehicles, tools, and software.
Target profit — The specific margin you want on top of all costs. Set it as a percentage or a flat dollar amount.

The result is a professional service price that ensures every cost is covered while keeping your profit margin exactly where it needs to be for long-term growth.

Example: pricing a 4-hour plumbing job

Here is how a plumbing company might price a water heater installation using cost-plus pricing:

Labor	2 workers × 4 hrs × $35/hr = $280
Materials	$150
Overhead	$75
Total cost	$505
Profit (20% margin)	+$126
Service price	$631

The 20% profit margin means $126 stays in the business after labor, materials, and overhead are covered. The markup on cost is 25% ($126 ÷ $505).
