Break-Even Calculator for Contractors: Know Your Number

$40,000. That is the number one remodeler I know has to bill every single month just to keep the doors open, before he makes a dime of profit. He had no idea. He thought as long as jobs were coming in, he was fine. Then a slow February nearly sank him.

That number has a name. It is your break-even point, and if you run a contracting business and cannot say yours out loud right now, you are flying blind.

A break-even calculator tells you exactly how much revenue you need to bill to cover every dollar going out the door. Not profit. Survival. Use our free Break-Even Calculator to run your own numbers in under a minute, then come back and I will walk you through what they actually mean.

Quick Answer: What Is a Contractor’s Break-Even Point?

Your break-even point is the total revenue you must bill to cover all fixed and variable costs, with zero profit left over. For most small remodeling businesses, that lands somewhere between $30,000 and $60,000 a month once you add up overhead and account for your gross margin. The formula is simple: divide your monthly fixed overhead by your gross profit margin. If your overhead is $12,000 a month and your gross margin is 30 percent, you need to bill $40,000 a month to break even.

The Break-Even Formula, Plain and Simple

There is one equation you need to burn into memory:

Break-Even Revenue = Fixed Overhead ÷ Gross Margin %

Two inputs. That is it. The hard part is being honest about both of them.

• Fixed overhead is everything you pay whether or not you have a single job running. Rent, insurance, truck payments, software, your phone, the office help, advertising.
• Gross margin is the slice of each job’s revenue left after you pay the direct costs of doing that job. Materials, field labor, subs, permits, dumpster.

Most contractors get the overhead number wrong because they forget half of it. I did too, early on. I counted the truck payment and insurance and figured that was overhead. I forgot the phone, the accountant, the software subscriptions, the gas, the tools I replace every year. Add it all up and the real number is usually double what you guessed.

Step 1: Add Up Your Real Monthly Overhead

Overhead is the silent killer. It does not show up on any single job, so it is easy to ignore until a slow month exposes it.

Here is what a typical small remodeling outfit pays every month, based on field experience running this kind of shop in the Pacific Northwest. Your numbers will differ, but the categories rarely do.

Overhead Item	Typical Monthly Cost
General liability + workers comp insurance	$1,200 - $2,500
Truck payment + fuel + maintenance	$1,400 - $2,200
Office/admin help (part-time)	$1,500 - $3,000
Phone, internet, software (estimating, accounting)	$300 - $700
Advertising and lead generation	$800 - $2,500
Tools, equipment replacement, small purchases	$400 - $900
Accountant, legal, licensing, bonds	$300 - $600
Total fixed overhead	$5,900 - $12,400

Notice none of that is tied to a specific job. You pay it in January when you are slammed and you pay it in February when the phone goes quiet. That is what makes it dangerous.

Run your own categories through our Contractor Overhead Calculator to get a clean monthly number before you go any further. Garbage in, garbage out. If your overhead figure is soft, your break-even number is worthless.

Step 2: Nail Down Your Gross Margin

Gross margin is where most contractors trick themselves. They confuse markup with margin, and the two are not the same.

• Markup is what you add on top of cost. A 30 percent markup on $10,000 of cost gives you $13,000.
• Margin is what is left as a percentage of the final price. On that $13,000 job, your $3,000 profit is only a 23 percent margin.

Mix those up and your break-even math is off by thousands. I dig into the difference in detail in markup vs margin, and you can check your own numbers with the Profit Margin Calculator.

For break-even, you always use gross margin. Industry O&P (overhead and profit) markup runs 15 to 35 percent per NAHB and RSMeans benchmarks, with 25 percent being a fair midpoint for residential remodeling. That translates to a gross margin most healthy small contractors should target in the 25 to 40 percent range. If yours is sitting at 15 percent, you have a pricing problem, not a volume problem.

Step 3: Run the Break-Even Number

Now put the two together. Here are two worked examples so you can see how it plays out.

Example 1: The lean one-truck remodeler

• Monthly fixed overhead: $8,000
• Gross margin: 30 percent
• Break-even revenue = $8,000 ÷ 0.30 = $26,667 per month

That contractor needs to bill roughly $26,700 a month just to stay even. Anything above that is profit. Anything below, and he is paying to work.

Example 2: The growing crew

• Monthly fixed overhead: $12,000
• Gross margin: 28 percent
• Break-even revenue = $12,000 ÷ 0.28 = $42,857 per month

Bigger overhead, slightly thinner margin, and the break-even jumps to nearly $43,000 a month. This is the trap of growth. You add a second truck and an office helper, your overhead climbs, and suddenly you have to bill 60 percent more just to stand still.

Here is the part nobody tells you. If you raise that contractor’s margin from 28 to 35 percent, his break-even drops to $34,286. Same overhead. Better pricing. That is a $8,500 a month swing from one number. Pricing beats hustle.

Per-Job Break-Even: Will This Bid Actually Pay?

Monthly break-even tells you the big picture. But you also want to know whether a single bid carries its share of the load.

Every job has to cover three things: its own direct costs, a slice of your monthly overhead, and your profit. A common method is to allocate overhead as a percentage of direct costs.

Say your direct costs on a bathroom remodel come to $14,000 (materials, labor, subs, permit, dumpster). Pull a few of those from real ranges:

• Carpenter labor: $30/hour typical (BLS 47-2031 carpenter wages)
• General labor: $22/hour typical (BLS 47-2061 construction laborer)
• Building permit: around $1,200 (Angi 2026 residential average)
• Dumpster rental: about $475/week (Angi 2026 roll-off guide)

If your overhead runs roughly 15 percent of revenue and you want a 12 percent net profit, you mark that $14,000 up enough to land near $19,000 to $20,000 to the customer. Bid it at cost plus a thin markup and you lose money the second anything goes sideways. And on a remodel, something always goes sideways.

What Wrecks Your Break-Even Math

These are the mistakes I see contractors make over and over, and the ones that burned me early on.

1. Forgetting your own pay. If you are not paying yourself a real wage as a line item, your break-even is a fantasy. Your time is a cost.
2. Counting revenue as profit. Revenue is not profit. Cash in the bank does not mean the job made money. I learned that the hard way reading The E-Myth after my second rough year.
3. Ignoring slow seasons. Your break-even is monthly, but work is lumpy. A great spring does not erase a dead winter. Average across the year.
4. Lowballing overhead. The number is always bigger than you think. When in doubt, round up.
5. Using markup when you mean margin. A 25 percent markup is only a 20 percent margin. That gap compounds across every job.

Regional Reality Check

Costs swing hard by market. Labor in Seattle or the Bay Area runs well above the national average, while rural markets sit below it. Insurance, advertising, and rent all shift with your region too. Treat every range here as a 2026 national starting point, not gospel. Pull your own real bills, get local quotes on your fixed costs, and run the math on your actual numbers. A break-even built on someone else’s overhead is just a guess in a nicer outfit.

Frequently Asked Questions

How do I calculate my break-even point as a contractor? Divide your total monthly fixed overhead by your gross profit margin expressed as a decimal. Overhead of $10,000 at a 30 percent margin means $10,000 ÷ 0.30 = $33,333 in monthly revenue to break even. Run it fast with the Break-Even Calculator instead of doing it on a napkin.

What is a good gross margin for a contractor? Most healthy small remodeling businesses target 25 to 40 percent gross margin. Below 20 percent and you have almost no cushion for the surprises that come with every remodel. NAHB and RSMeans peg standard O&P markup at 15 to 35 percent, which supports that margin range.

Is break-even the same as my hourly rate? No. Your break-even is a total revenue target for the business. Your hourly rate is what you charge per hour of labor. They connect, but they answer different questions. Figure your rate separately with a tool like the Labor Cost Calculator, then make sure your jobs collectively clear break-even.

How does break-even change when I hire my first employee? It jumps, and faster than most contractors expect. A new hire adds wages plus payroll burden (taxes, workers comp, insurance) that can run 25 to 40 percent on top of the base wage. That all lands in overhead or job cost, pushing your monthly break-even up. Price for it before you hire, not after.

Why does raising my margin lower my break-even so much? Because break-even is overhead divided by margin. A bigger margin means each dollar of revenue covers more overhead, so you need fewer total dollars. Moving from a 28 to 35 percent margin on $12,000 of overhead drops break-even by over $8,000 a month without selling a single extra job.

Stop Guessing Your Number

Knowing your break-even changes how you bid. You stop chasing every lead and start chasing the right ones. You quit taking jobs that look busy but pay nothing. You price with confidence because you know exactly where the line is.
