Contractor Break-Even Calculator
Break-even is not a revenue figure you guess at in January. It is the point where the gross profit your jobs produce finally covers the costs that run whether you sell work or not.
This contractor break-even calculator takes your fixed costs, your gross margin and your average job size, then returns the revenue you have to book to stay level, the number of jobs that represents, and what the target becomes once you add the profit you actually want to earn.
How break-even is actually calculated
- Fixed costs firstRent, insurance, office wages, your own salary
- Gross margin, not markupMargin is profit divided by price, not by cost
- Contribution margin per jobAverage job price multiplied by gross margin
- Break-even revenueFixed costs divided by gross margin
- Break-even jobsFixed costs divided by contribution per job
- Profit goes in lastFixed costs plus target profit, divided by margin
Fixed costs stay the same whatever you sell; variable costs move with the work and are already inside gross margin. Worked through: $12,000 a month in fixed costs, a $20,000 average job at a 30% gross margin. Each job contributes $6,000, so two jobs a month is break-even and the third is the first one that pays you anything.
Your break-even point, by the month and by the year
Enter your own fixed costs, gross margin and average job size. This is a break-even analysis for a construction or remodeling business, so the calculator returns break-even revenue, the job count behind it, and the revenue a stated profit target requires.
Three places contractors get break-even wrong
The formula is simple arithmetic. The inputs are where companies quietly build a break-even that is lower than reality, then wonder where a busy year went.
Your own pay is a fixed cost
A break-even that assumes you work free is not break-even, it is a loss you are personally financing. Put a market-rate salary for the role you actually perform into fixed costs before you calculate, the same way you would for an office manager, and let profit be whatever survives after it.
Divide by margin, not by the job price
Each job pays your fixed costs only with its gross profit, not with its invoice total. That figure is the contribution margin: a $20,000 job at a 30% gross margin contributes $6,000, so it takes two of them to carry $12,000 of monthly overhead. Divide by the price instead and you will believe one job a month is enough.
Convert the revenue into bids
A revenue target is not something a crew can act on. Divide it by average job size for the job count, then divide that by your own closing percentage for the number of estimates you have to produce. Estimating time is overhead you pay whether the job sells or not, and what each of those bids costs to generate is your cost per lead.
The break-even point formula, run three ways:
The margin your break-even depends on
Break-even moves with one number more than any other, and it is not your overhead. It is the gross margin every job contributes. Here is what the published survey figures look like for remodelers.
29.9%
Average gross profit margin for remodelers on fiscal 2024 revenue, per the NAHB Remodelers' Cost of Doing Business Study. That is the share of each job that is available to pay fixed costs, which makes it the denominator in your break-even revenue.
6.3%
Net profit margin for the same group, after operating expenses of 23.6% of revenue. If your own break-even shows you need every job running at industry-average net simply to stay level, there is no cushion in the year for one bad job.
4.7%
Net margin remodelers reported for 2021, against 5.2% in 2018. NAHB called the 2024 figure the highest it has recorded since 1996, which tells you that the good year is 6.3% and the normal year is closer to five.
Do not build your break-even on any of these three. They are survey averages across company sizes, trade mixes and markets, and a one-truck operation and a company with an office and six vans do not share a gross margin. Use them to sanity-check the number your own books produce, then use your own number.

Break-even questions, answered
How many jobs a month do I need to cover my fixed costs?
Divide monthly fixed costs by the gross profit an average job produces, not by the job's price. At $12,000 in monthly overhead and a typical $20,000 job at a 30% gross margin, each job contributes $6,000 of contribution margin, so two closed jobs a month is break-even. NAHB reported remodelers averaging a 29.9% gross margin on fiscal 2024 revenue, which is a reasonable sanity check on your own figure.
Do I include my own pay in break-even?
Yes, and it goes in fixed costs before you calculate anything. A break-even that assumes you work free is not break-even, it is a loss you are financing personally. If the resulting revenue target looks impossible for your crew size, the problem is your price or your capacity, and a spreadsheet in January is a cheaper place to find that out than a bank balance in March.
Is break-even the same for service work and bid work?
The method is identical, the inputs are not. Service carries more trucks, more windshield time and fewer billable hours per paid hour, so fixed costs and break-even revenue run higher per technician. Bid work and new construction spread a leaner overhead across longer runs of billable field hours. Run the calculator once per division rather than blending a service van and a framing crew into one average.
How does my close rate change the number?
It converts a revenue target into a workload. Whatever your rate is, it sets how many estimates you must produce to reach break-even, and estimating time is overhead you pay on every bid that does not sell. Track closed jobs divided by bids issued over the last twelve months and use your own figure; no published bid-to-close average for residential contractors survives a look at its sourcing.
How do I set a revenue target that leaves an actual profit?
Add the profit you want to the fixed-cost line and solve the same equation. Required revenue equals annual fixed costs plus target profit, divided by gross margin. At $150,000 in fixed costs, a $60,000 profit target and a 30% gross margin, you need $700,000 in volume. Margin has more leverage than either of the other two inputs, which is why price discipline beats chasing volume.
What is a normal net profit for a remodeling company?
Remodelers averaged 6.3% net profit on fiscal 2024 revenue, against 4.7% in 2021 and 5.2% in 2018. NAHB describes 2024 as the highest it has recorded since 1996. That is after the owner's salary in a properly built P&L, so a company paying its owner out of profit is not comparing like with like when it measures itself against the figure.
Knowing the number is the easy half
The calculator tells you how many jobs a month keep you level. Whether enough qualified people are asking you to bid is a demand problem, and it is the one that decides whether the number is reachable.
