How to Calculate Your Break-Even Point as a Home Service Business
Most home service owners know their revenue but not whether it is enough to cover costs. The break-even calculation tells you exactly what monthly revenue you need before a single dollar of profit appears.
Key takeaways
- Break-even revenue equals fixed monthly costs divided by gross margin percentage. Below that number, every job creates a loss regardless of how busy the operation looks.
- Adding one technician at $65,000 per year raises the break-even by $10,415 per month at a 52 percent gross margin, not $5,416. The fixed cost addition compounds through the gross margin divisor.
- Gross margin percentage is the most important input in the break-even calculation. A 5-point margin improvement at $22,000 in fixed costs drops break-even by roughly $7,700 per month.
- Most home service businesses carry 40 to 55 percent gross margin. If yours is below 40 percent, the break-even problem is a pricing and cost problem before it is a revenue problem.
The break-even point is the revenue level at which the business covers all costs and produces zero profit. Below it, every job creates a loss. Above it, every job contributes to profit. Most home service owners do not know their break-even. They know revenue and hope the profit is there.
The hope strategy produces a common result: a business that looks busy, has a full schedule, generates $80,000 a month in revenue, and somehow ends every quarter short on cash. The revenue was above break-even in two months and below it in one, and nobody caught the third month because the first two felt fine.
The calculation takes about 20 minutes. Here is how to run it.
The break-even formula
Break-even monthly revenue equals fixed monthly costs divided by gross margin percentage.
Break-even = Fixed Costs / Gross Margin %
Gross margin percentage equals revenue minus direct job costs, expressed as a percentage of revenue. Direct job costs are the costs that exist only when a job runs: labor on the job, materials and parts for that job, subcontractors on that job. Nothing else.
Fixed costs are the costs that exist regardless of job volume: rent, vehicle payments, owner and admin salaries, insurance, software subscriptions, phone and utilities. These do not change whether you run 40 jobs this month or 80.
The formula produces the revenue floor. Every dollar below it is a net loss. Every dollar above it flows through at the gross margin rate.

Step 1: list your fixed costs
Fixed costs for a home service business typically include:
- Rent or shop lease
- Vehicle payments (truck loans, leases, van payments)
- Insurance premiums (general liability, commercial auto, workers comp)
- Owner salary drawn as a fixed paycheck
- Office and admin staff salaries
- Software subscriptions (CRM, scheduling, accounting, GPS tracking)
- Phone and internet
- Loan payments on equipment
- Marketing retainers (any spend that runs regardless of volume)
What is not a fixed cost: parts for jobs, job-level labor for field techs paid per job or hourly only when working, fuel on service calls, any subcontractor costs tied to specific jobs.
A two-tech HVAC or plumbing shop typically runs $18,000 to $28,000 per month in fixed costs before touching a single job. The exact number matters. Use your bookkeeping software, not an estimate. If the categories are blurred in your chart of accounts, this exercise surfaces that problem too.

Step 2: calculate gross margin
Gross margin percentage requires clean job-level cost data. For each job, the direct cost is:
- Field tech wages or billable hours on the job
- Parts and materials installed on the job
- Any subcontractor cost on the job
Gross profit per job = Revenue minus direct job cost. Gross margin % = Gross profit divided by revenue, times 100.
For a plumbing repair billed at $380 with $95 in parts and $110 in field labor: gross profit is $175, gross margin is 46 percent.
Run this across all jobs for the past 90 days and average the gross margin percentage. If your CRM and accounting system are connected, this is a report. If they are not connected, you are estimating, and estimates carry enough error to matter in the break-even calculation.
Industry ranges: residential HVAC typically runs 48 to 58 percent gross margin. Plumbing service runs 45 to 55 percent. Residential cleaning runs 35 to 50 percent. Landscaping maintenance runs 40 to 55 percent. Roofing replacement runs 35 to 48 percent. If your number is outside these ranges in either direction, the cost data may not be clean.

Step 3: the calculation
With fixed costs and gross margin in hand:
Example: $22,000 per month in fixed costs, 52 percent gross margin.
Break-even = $22,000 / 0.52 = $42,307 per month.
Below $42,307, the business is losing money regardless of how busy it appears. A month with $38,000 in revenue and 52 percent gross margin produces $19,760 in gross profit against $22,000 in fixed costs. That is a $2,240 operating loss before owner draw and taxes.
A month at $50,000 produces $26,000 in gross profit against $22,000 in fixed costs, a $4,000 operating profit. The difference between $38,000 and $50,000 in monthly revenue is the difference between losing money and making it, and neither month feels catastrophically different from inside the schedule.

How to use break-even to make decisions
The break-even calculation is most useful when a cost or pricing decision is on the table.
Adding a technician is the most common example. A tech at $65,000 per year in base compensation adds $5,416 per month to fixed costs. At 52 percent gross margin, covering that cost requires $10,415 of additional monthly revenue ($5,416 / 0.52). That is the minimum revenue the new tech must generate before break-even is maintained. If the tech averages $8,000 per month in billed revenue, the addition is a net loss every month. If the tech averages $14,000 per month, the addition pays back the cost and contributes $1,869 to profit. The capacity side of that decision is in when to hire the next technician.
Pricing works the same direction from the other side. If gross margin drops from 52 percent to 47 percent because of a price cut or a parts cost increase, and fixed costs stay at $22,000:
New break-even = $22,000 / 0.47 = $46,808.
The 5-point margin drop raises the break-even by $4,501 per month without touching a single fixed cost. Chasing volume to compensate requires more jobs, more labor, more truck time, which adds cost and can push margin down further. The pricing levers are in how to calculate overhead and markup and how to raise prices without losing customers.
The break-even calculation is not a one-time exercise. Monthly revenue versus the break-even threshold is the most useful single number a home service owner can watch. Pair it with how to read a profit and loss for home service so the P&L matches what break-even implies.

How Clint Calculates Break-Even from Your Business Data
Clint connects to your CRM (Jobber, Housecall Pro, ServiceTitan, Workiz) and accounting system (QuickBooks, Xero) and computes gross margin from actual job-level cost records. Ask "what is my gross margin percentage this month?" and Clint returns the number calculated from real revenue and real cost data, not an estimate. Ask "what are my fixed costs this month?" and Clint pulls the overhead expense categories from your books.
The break-even question then becomes a single text: "what is my break-even revenue based on last month's fixed costs and gross margin?" Clint runs the formula and returns the threshold. You compare it to the revenue number already on the screen and know instantly whether the month is profitable or not.

Frequently Asked Questions
4 questions home service owners actually ask about this.
01What is a typical gross margin for a home service business?
Ranges vary by trade. HVAC service typically runs 48 to 58 percent. Plumbing service runs 45 to 55 percent. Residential cleaning runs 35 to 50 percent. Landscaping maintenance runs 40 to 55 percent. Roofing replacement runs 35 to 48 percent. If your gross margin is below 35 percent and you are not in roofing or excavation, pricing or cost categorization likely needs attention.
02Is owner compensation a fixed cost or not?
It depends on how it is structured. A fixed owner salary drawn every month regardless of revenue is a fixed cost and belongs in the break-even numerator. Owner distributions that vary with profit are not a fixed cost. Most break-even analyses include a market-rate owner salary as fixed, because the business needs to replace that labor regardless.
03My revenue is above break-even but I have no cash. What is happening?
Break-even is an accrual concept. Cash flow problems can exist even when the business is technically profitable if receivables are slow, if large deposits were collected and then spent before the job ran, or if the business is servicing debt that is not in the fixed cost calculation. Run the break-even analysis alongside a cash flow projection, not instead of it.
04How often should I recalculate break-even?
Recalculate every time a material fixed cost changes. Adding a tech, signing a new lease, taking on a vehicle payment, or adding a significant software cost all change the break-even threshold. Monthly is a reasonable default for a growing business. Quarterly is acceptable for a stable operation.
