Ask a tradesperson what a job costs and you'll hear labor and materials. Both are real, both are easy to see - and together they leave out the single biggest reason busy people still end up broke. The costs of simply being in business don't attach to any one job, so they're easy to forget when you quote. Forget them long enough and they quietly eat your profit, job after job. This guide shows you how to find that number and build it into every price.
What overhead actually is
Overhead is the cost of running your business that no single job creates. You pay it whether you booked ten jobs this month or none. The clearest test:
Would you still pay it in a month with zero jobs booked? If yes, it's overhead. If it only exists because of one specific job - the materials for that job, a permit for that job - it's a direct job cost, not overhead.
For most independent tradespeople, overhead is some mix of these:
- Insurance - liability, and any tool, vehicle, or trade cover you carry.
- Vehicle - the payment or lease, fuel for getting around, servicing, tires, registration.
- Tools and equipment - the spread-out cost of buying and replacing the kit you use across every job, not consumables for one.
- Phone and internet - the line customers call and the data you run the business on.
- Software and subscriptions - invoicing, accounting, scheduling, cloud storage.
- Accounting, licenses, and fees - your bookkeeper or accountant, license renewals, bank and merchant account fees.
- Marketing - your website, listings, ads, van signage, business cards.
- Premises - if you rent a yard, unit, or storage; home-based operators may have little or none here.
Notice what's not on the list: the materials for a specific job, and the hours you spend on site. Those belong to the job itself - materials in the materials line, your time in the labor line. Overhead is everything else that keeps the lights on around the work.
Step 1: total up a year of overhead
Use a whole year, not a single month, so one-off and seasonal costs (an annual insurance premium, license renewals, a tool replacement) get averaged in instead of skewing the number. Go through your bank and card statements for the last twelve months and add up every overhead item. Here's an illustrative tally for a one-person operation:
| Liability & tool insurance | $3,000 |
|---|---|
| Vehicle (payment, fuel, servicing) | $8,400 |
| Phone & internet | $1,440 |
| Tools & equipment (replacement) | $1,800 |
| Software & subscriptions | $960 |
| Accounting, licenses & fees | $1,200 |
| Marketing | $1,200 |
| Yearly overhead | $18,000 |

Your real list will look different - that's the point. Home-based operators may have no premises cost; someone running two vans will spend far more on vehicles. Build the tally from your own statements, not this example.
Step 2: turn it into a percentage
A dollar total isn't much use when you're quoting a single job. You need a rate that scales - so a big job carries more overhead than a small one automatically, without you doing the sum each time. That's why overhead is usually applied as a percentage. Divide your yearly overhead by the total labor, materials, and travel you build your prices on across the same year:
"Yearly job costs" here means the sum of the labor, materials, and travel that go into your quotes over the year - the base your prices are built on, before overhead and profit. Say that came to about $120,000. Then:
So this business adds 15% to each job's costs to recover its overhead. Run more work through the same fixed costs and the percentage drops; carry heavy overhead on thin volume and it climbs. Either way, it's now a single number you can apply to any quote.
Your overhead percentage is a way of spreading fixed costs fairly across your jobs - it's an allocation, not an exact invoice for what a specific job "used" of your insurance. That's fine. The goal is that by year's end, the overhead collected across all your jobs adds up to the overhead you actually paid. Revisit the percentage once a year, or whenever your costs or your volume change noticeably.
Step 3: build it into the price
Overhead sits between your job costs and your profit. You total the direct costs of the job, add your overhead percentage on top to get your true cost, and only then add profit. Take a job with a $700 subtotal - that's labor, marked-up materials, and travel combined:
| Job subtotal (labor + materials + travel) | $700.00 |
|---|---|
| Overhead (15% of subtotal) | $105.00 |
| Your true cost | $805.00 |
| Profit (20% margin) | $201.25 |
| Price you quote | $1,006.25 |
Illustrative example — figures chosen to show the method, not a quote. How we source figures.
The overhead line adds $105, lifting your real cost to $805. The 20% profit margin is then a share of the final price, so the price is $805 ÷ (1 − 0.20) = $1,006.25 (that true-margin divide is covered in markup vs. margin). Skip the overhead step and you'd have priced from a $700 cost - and that missing $105 would have come straight out of your profit on every job like it.
Because it's a percentage, it scales on its own. Here's the same $700 subtotal at different overhead rates, each then priced at a 20% margin:
| Overhead % | Overhead added | True cost | Price at 20% margin |
|---|---|---|---|
| 10% | $70.00 | $770.00 | $962.50 |
| 15% | $105.00 | $805.00 | $1,006.25 |
| 20% | $140.00 | $840.00 | $1,050.00 |
| 25% | $175.00 | $875.00 | $1,093.75 |

Two mistakes that undo all this
- Counting your own time as overhead - or not at all. The hours you work on a job belong in that job's labor cost, so you're paid for them. Overhead is the business cost around the work. Blur the two and you either double-count your wage or, more often, forget to pay yourself. Count your time once, in labor, and keep overhead separate.
- Confusing overhead with profit. Overhead recovers costs you already pay; margin is profit on top of covering everything. A job that only breaks even has covered its overhead and earned you nothing. Keep them as two separate lines - see what's a good profit margin - so you always know whether a price is merely safe or actually worth doing.
Set your overhead once - it rides on every quote
TradeReady takes your overhead as a percentage and applies it to every job automatically, so the cost of being in business is always in the price without you thinking about it. It sits in the calculator between your job costs and your profit margin - exactly the order this guide describes - and feeds the break-even floor, so you can see the price that covers your overhead with nothing to spare.

The bottom line
Overhead is the cost of being in business that no single job asks for - so you have to make every job pay a share. Total a year of it, divide by the year's job costs to get a percentage, and add that percentage on top of each job's costs before you add profit. Do it once and the truck, the insurance, and the phone bill get paid by the work, instead of quietly coming out of you.
Common questions
What counts as overhead for a tradesperson?
Overhead is the cost of being in business that no single job causes: insurance, your vehicle, tools and equipment, phone and internet, software, accounting and license fees, and advertising. The test is simple. If you would still pay it in a month with no jobs booked, it is overhead. Costs tied to one specific job, like the materials for that job or a permit for it, are direct job costs, not overhead.
How do I calculate my overhead percentage?
Add up your overhead costs for a year, then divide by the total labor, materials, and travel you build your prices on over that same year. Overhead percentage = yearly overhead divided by yearly job costs. For example, 18,000 dollars of yearly overhead divided by 120,000 dollars of yearly job costs is 0.15, or 15%. That is the percentage you add to each job's costs so your overhead is recovered across all the work you do.
Is overhead a dollar amount per hour or a percentage?
You can think about overhead either way, but it is usually applied as a percentage of a job's costs, because that scales automatically with the size of the job. A big job carries more overhead than a small one without you recalculating anything. TradeReady applies overhead as a percentage of the job subtotal, not as a fixed dollar figure per hour.
Does overhead include my own wages?
It depends on how you set your business up, and it is important not to count your labor twice. In most job-costing setups, the hours you work on a job are part of that job's labor cost, not overhead, so you get paid for the time you spend on site. Overhead then covers the business costs that are not tied to any one job. Whichever way you split it, make sure your own time is paid somewhere, and only counted once.
What is a normal overhead percentage in the trades?
There is no official figure, and it varies widely with how much equipment, insurance, premises, and marketing a business carries. A one-person operation working from a home base has very different overhead from a business running several vehicles and a yard. Rather than borrow a percentage, calculate your own from your real costs. The number that matters is the one your actual business produces.
What happens if I do not include overhead in my prices?
The overhead does not disappear; it comes out of your profit instead. If you price only labor and materials, every job silently donates a share of your insurance, vehicle, and tools, and you end up busy but with far less left over than you expected. Building overhead into each price is how those costs get paid by the work that creates the need for them, rather than by you.
- The overhead tally and pricing figures above are arithmetic worked through on a sample business; the method is standard small-business job costing. See how we research these guides.
- There is no standard or "average" trade overhead percentage offered here as fact; the illustrative figures are for method only. Calculate your own from your real yearly costs and job volume.
- Overhead recovers costs, not profit; keep it separate from your profit margin, and count your own labor once, in the job's labor line.
