How to Calculate Your Break-Even Point as a Contractor

Your break-even point is the amount of revenue you need to bring in each month just to keep the lights on without making a dime of profit. For most contractors running $1M to $3M in annual revenue, that number sits somewhere between $60K and $150K per month depending on overhead. If you don't know your number, you're flying blind on which jobs to take and how much margin you actually need to stay afloat.

Why Your Break-Even Point Matters More Than You Think

Here's the thing nobody tells you when you hang your shingle: you can be busy as hell and still go broke. I've sat with roofers who did $2.3M in revenue last year and paid themselves $47K. I've seen HVAC contractors turn down work because they were 'too busy' while their line of credit crept up every month. The problem wasn't the work. It was that they had no idea what their break-even point was, so they couldn't tell a profitable job from one that just kept them busy.

Your break-even point is the minimum revenue you need to cover your fixed costs before a single dollar goes to profit or your own pocket. It's not your sales goal. It's not what you want to make. It's the floor. Below that number, you're paying to work. Above it, you're actually making money. And most contractors I meet have never calculated it, which means they're pricing jobs based on gut feel and hoping it works out.

The math isn't complicated. But it does require you to know your actual overhead, which is where most contractors get stuck. If your books are a mess or you're not separating job costs from business costs, you can't calculate break-even accurately. That's why getting your job costing system dialed in matters so much.

What Counts as Fixed Costs (And What Doesn't)

Fixed costs are the expenses that hit your bank account whether you sell a single job or not. These are the bills you pay just to keep the business operational. For a typical specialty contractor doing $1M to $3M annually, fixed costs usually include:

• Office rent or shop lease
• Insurance (general liability, workers comp base premium, vehicle insurance)
• Truck and equipment payments
• Utilities and phone
• Software subscriptions (estimating, project management, accounting)
• Salaries for office staff or project managers who aren't tied to specific jobs
• Your own salary or owner's draw if you're pulling a consistent amount
• Marketing and advertising
• Professional fees (accountant, legal, licensing)

What doesn't count: direct job costs like materials, subcontractors, hourly labor on specific jobs, job-specific permits, or dumpsters. Those are variable costs that scale with revenue. If you don't sell a job, you don't incur those expenses. Break-even is about covering the stuff you pay no matter what.

Let's use a real example. Say you run a residential remodeling company. Your fixed monthly costs look like this: $2,500 shop rent, $3,200 insurance, $1,800 truck payments, $450 software and phones, $4,500 office manager salary, $6,000 your own draw, $800 marketing, $500 accounting. That's $19,750 per month in fixed overhead. That's your break-even revenue target assuming zero margin, which obviously doesn't work. We'll fix that in a minute.

How to Calculate Your Monthly Break-Even Revenue

Here's the formula: Break-Even Revenue = Fixed Costs ÷ Gross Profit Margin. Your gross profit margin is what's left after you pay for direct job costs but before you pay overhead. If you typically run a 30% gross margin (meaning job costs eat 70% of revenue), then your break-even revenue is your fixed costs divided by 0.30.

Using our remodeling example with $19,750 in monthly fixed costs and a 30% gross margin: $19,750 ÷ 0.30 = $65,833 per month in revenue just to break even. That means if you bill less than $65,833 in a month, you're losing money. If you bill $80,000, you're making $4,250 in net profit after covering everything. If you bill $100,000, you're making $10,250 in profit.

Most contractors don't know their actual gross margin, which makes this calculation impossible. If you're not tracking job costs separately from overhead, go back and pull the last three months of completed jobs. Add up all the direct costs (labor, materials, subs, equipment rental). Subtract that from the total revenue on those jobs. Divide the difference by the total revenue. That's your gross margin percentage. If it's below 25%, you've got a pricing problem or a job cost leak.

Here's another example for a commercial GC doing larger projects. Your fixed costs are higher: $8,500 office rent, $6,800 insurance, $2,200 vehicles, $1,200 software, $12,000 PM salaries, $10,000 owner salary, $1,500 marketing, $800 accounting. That's $43,000 per month. If you run a 22% gross margin (common for GCs with lots of sub work), your break-even is $43,000 ÷ 0.22 = $195,455 per month. That's $2.3M annually just to keep the doors open.

What to Do When You're Below Break-Even

If you run the numbers and realize you've been operating below break-even for months, don't panic. You're not alone. Most contractors go through stretches where revenue dips, especially in winter or during slow booking periods. The question is what you do about it.

First, get ruthlessly honest about your fixed costs. Are there expenses you're treating as 'necessary' that could be cut or paused? I'm not saying fire your office manager or cancel your insurance. But maybe the $800/month software you never use can go. Maybe the second truck that sits in the yard most days can be sold. Maybe your own draw can flex down for a few months while you dig out.

Second, look at your margin. If your gross profit margin is 18% and your break-even requires 25%, you don't have a revenue problem—you have a pricing or cost control problem. Pull your last five jobs and compare estimated costs to actual costs. Where did the overruns happen? Materials? Labor hours? Subs who billed more than quoted? Fixing margin is faster than chasing more revenue, and it compounds on every job you sell.

Third, figure out how much revenue you actually need to hit your income goal, not just break-even. If you want to take home $120K per year after covering all costs, that's $10K per month in net profit on top of your break-even. Using our remodeling example with a 30% margin and $65,833 break-even, you'd need to add $33,333 in revenue per month to generate that $10K profit. So your target becomes $99,166 per month, or about $1.19M annually. Now you have a real sales goal, not just a guess.

How to Use Break-Even to Make Better Decisions

Once you know your break-even number, it changes how you think about every job, every hire, and every expense. Let's say you're thinking about adding a project manager at $65K per year (about $5,400/month with taxes). That increases your fixed costs by $5,400, which means your break-even revenue goes up by $18,000 per month if you're running a 30% margin. Can that PM help you sell or deliver an extra $18K per month? If yes, it's a good hire. If no, hold off.

Same logic applies to taking on a job that's lower margin than usual. Let's say your normal gross margin is 32%, but a GC offers you a commercial project that'll only net 20% because it's competitive and you need the work. If the job brings in $150K in revenue at 20% margin, that's $30K in gross profit. If your monthly fixed costs are $22K, that job covers overhead for 1.4 months. Not ideal, but if it fills a gap and keeps your crew working, it might be worth it. At least you're making the decision with your eyes open instead of hoping it works out.

You can also use break-even to stress test your business. What happens if revenue drops 20% next quarter? Run the numbers. If your break-even is $70K per month and you're currently averaging $95K, a 20% drop puts you at $76K—still above water, but barely. That tells you that you've got a thin margin for error and might want to build up cash reserves or look at trimming fixed costs before a slowdown hits.

Understanding your cash flow in relation to break-even is critical too, especially if you're dealing with retainage or slow-paying clients. You might be above break-even on paper, but if $40K of your revenue is stuck in retainage or unpaid invoices, your bank account doesn't care. This is why tracking both your P&L and your cash position matters.

The Link Between Break-Even and Pricing Strategy

Here's where this gets practical for Monday morning. If you know your break-even and your target margin, you can reverse-engineer what you need to charge on every job. Let's say you're an electrician and your break-even is $48K per month with a 35% gross margin. You typically run two project crews. That means each crew needs to generate $24K in revenue per month, or about $6K per week, just to break even.

If a job is going to take your crew three days and your break-even is $6K per week, that job needs to bring in at least $3,600 just to cover overhead, plus the direct costs of labor and materials, plus your profit margin. So if the job costs you $2,000 in materials and labor, you need to charge at least $5,600 to hit a 35% margin and cover your share of overhead. Suddenly pricing isn't a mystery. It's just math.

Most contractors underprice because they only think about direct costs. They figure materials and labor, add 20%, and call it good. But they forget that every job has to carry its share of overhead. If you're not building your fixed costs into your pricing, you're subsidizing your clients with your own profit. That's why busy contractors go broke.

When to Recalculate Your Break-Even

Your break-even isn't static. Every time your fixed costs change, your break-even changes. Hired someone? Bought a truck? Moved to a bigger shop? Recalculate. Your margin shifts over time too, especially if you're moving into different types of work or dealing with material cost swings. I recommend running this calculation quarterly, or any time you make a significant change to your cost structure.

Seasonal contractors need to think about break-even differently. If you're a roofer in the Midwest and you basically don't work January through March, your break-even calculation has to account for covering twelve months of fixed costs in nine months of revenue. That means your effective monthly break-even during working months is higher. If your annual fixed costs are $240K and you work nine months, you need to average $26,667 per month during those nine months just to break even, not the $20K you'd need if you worked year-round.

If you've never done this exercise, block an hour this week and run the numbers. Pull your P&L, separate your fixed costs from your variable costs, calculate your gross margin on recent jobs, and plug it into the formula. It's one of the highest-leverage hours you can spend in your business. And if your books are too messy to even attempt this, that's a sign you need to get your financial system cleaned up before you make any other big decisions.

The Bottom Line

Knowing your break-even point won't solve all your problems, but it'll stop you from making decisions in the dark. It's the foundation for pricing, hiring, cash planning, and figuring out whether you're actually making money or just staying busy. Most contractors never calculate it, which is why most contractors feel like they're working harder every year for the same or less money. You don't have to be most contractors. Do the math. Know your number. Make decisions accordingly.
