Enter your weekly job count, average job value, and real cost structure to get a full monthly profit picture for your electrical contracting business — materials, labor, vehicle, and net margin all included.
You billed $22,000 last month and the bank account says you are somehow tired and broke. The money went where it always goes in electrical work: a pallet of breakers and wire from the supply house, the helper's wages, the van payment that hits whether you ran eight jobs or fourteen. This calculator surfaces the gap between what the invoices say and what the business actually keeps. Enter Jobs Per Week, Working Weeks Per Month, Average Job Value, your Materials/Parts Cost percentage, and flat monthly costs for labor, vehicle, overhead, and marketing — and the tool returns profit per job, monthly net, and overall margin.
The Pricing Impact Analysis tab is where this tool earns its keep. Raise or lower your average job value and see exactly how monthly profit changes at your current volume and cost structure. For an electrical contractor pricing service calls, panel upgrades, and installation jobs, knowing the profit impact of a $50 change in average ticket is more useful than a generic 'raise your rates' suggestion.
How job value and materials cost interact in electrical work
Electrical work is materials-intensive. A service panel upgrade might bill out at $2,500 with $900 in breakers, wire, and conduit — a 36% materials cost. A troubleshooting call that bills at $250 with $20 in wire nuts and tape runs at 8% materials. Your average Materials/Parts Cost percentage for the month reflects the mix of job types you run, not any single job.
The calculator takes your blended materials percentage and converts it to a dollar amount against gross monthly revenue. On $22,000 gross with 22% materials cost, that is $4,840 per month going to supply houses and hardware. Seeing that in dollars — rather than as a percentage — tends to sharpen the focus on supply cost management and whether your pricing is actually covering the materials on each job type.
One useful exercise: run the calculator at your current average job value, note the net profit, then lower the materials percentage by three points and note what happens. A three-point improvement on $22,000 gross is $660 per month. That is the value of negotiating better supplier pricing, buying in bulk, or being more precise in your material estimates.
What a real electrical business P&L looks like
A solo electrician running 12 jobs per week at an average $350 job value over 4.33 weeks per month generates about $18,200 in gross monthly revenue. Materials at 24% is $4,368. Monthly labor (including the owner's wage) at $7,500. Vehicle and fuel at $1,100. Overhead — insurance, licensing, tools, software — at $800. Marketing at $400. Total costs: $14,168. Net profit: $4,032 at a 22% margin.
That is a healthy single-person operation. Adding a helper or apprentice changes the math: labor jumps by $3,000–$3,500 per month and gross revenue may increase by $4,000–$6,000 if the helper enables more jobs. The net outcome depends entirely on whether the extra capacity is filled. The calculator lets you model both scenarios — solo and with a helper — before making the hire.
The Business Verdict in the tool flags when margin falls below healthy thresholds (typically below 15% for a trade contractor) and when it is strong enough to support growth decisions. If your actual numbers come back thin, the tool surfaces which cost category is the problem.
Vehicle and fuel as a fixed cost versus a variable one
The calculator treats Monthly Vehicle/Fuel as a flat dollar amount, which is the right approach for a service van with relatively predictable costs. Loan payment, commercial auto insurance, fuel, and an amortized maintenance reserve are all real monthly commitments regardless of job volume.
A service van with a $650/month payment, $350/month in insurance, $300/month in fuel, and $200/month in amortized maintenance is a $1,500/month fixed cost. On 12 jobs per week, that is about $34 per job in vehicle cost alone. On 8 jobs per week, it is $52 per job. Volume affects whether vehicle cost is a manageable overhead or a serious margin drag.
If you are weighing a second truck, the math gets simple in the calculator: increase Monthly Vehicle/Fuel by the cost of the second vehicle, increase monthly labor by the second electrician's wages, and see at what job volume the expansion breaks even. Most electrical contractors who model this find the answer is higher than they expected — because the second truck needs to generate enough revenue to cover both the truck cost and a full year of its own share of overhead.
Pricing your service call rate against real cost
The service call rate is where most electrical businesses leave money on the table or price themselves out of work. The calculator's Pricing Impact Analysis generates a table of monthly profit at different average job values, which shows you what your breakeven job value is given your current cost structure.
At $22,000 in monthly costs (including all labor, materials, vehicle, and overhead), you need $22,000 in gross revenue to reach zero. With 52 jobs per month, that is $423 per job to break even. Every dollar above that is profit. If your average job value is $350, you are losing money at that volume. If it is $500, you are making $77 per job before marketing.
This is why the tool explicitly separates fixed and variable costs rather than lumping everything together. Fixed overhead does not change when you take a $200 service call versus a $2,500 panel job — but materials cost does. Knowing your true break-even per job helps you decide which jobs to take and which to decline or reprice.
Using Profit Per Job to benchmark your operation
The Profit Per Job metric at the top of the dashboard divides net monthly profit by total monthly jobs. It is a simple number, but it cuts through a lot of noise. If you are running hard and netting $35 per job after everything is paid, something in the cost structure is off — either your average job value is too low, your materials cost is too high, or your overhead is out of proportion to your volume.
Profitable electrical contractors typically target $80–$150 or more in net profit per job depending on their market and job mix. Running above that range on high-ticket commercial work is common; falling below on competitive residential service calls is also common. The calculator shows you where you actually are rather than where you feel like you should be.
Export your scenario as CSV and hand it straight to a client or partner. A clean monthly profit projection is useful not just for internal planning but for conversations with a bank, a partner, or an accountant — showing real numbers rather than estimates makes every financial conversation faster and more productive.
How to use it
- Enter Jobs Per Week and Working Weeks Per Month — use your real monthly average, including slow weeks.
- Set Average Job Value ($) to your actual effective rate per job: total monthly revenue divided by total jobs completed.
- Enter Materials/Parts Cost (%) as your blended materials percentage across all job types in a typical month.
- Fill in Monthly Labor Cost ($), Monthly Vehicle/Fuel ($), Monthly Overhead ($), and Monthly Marketing ($) as flat dollar amounts.
- Read Profit Per Job, Profit Margin, and Net Profit in the summary cards, then use the Pricing Impact tab to test rate changes.
Who it's for
- Solo electrician pricing residential service calls — Discovers that a $75 minimum service call at current volume does not cover vehicle and overhead costs per job, and uses the Pricing Impact tab to find the minimum rate that hits 20% margin.
- Two-man shop evaluating a third electrician hire — Models the increased labor cost against the additional 10 jobs per week the hire enables and finds the margin holds — but only if the new capacity is at least 80% utilized from month one.
- Electrical contractor preparing a bank line of credit application — Exports a clean monthly profit projection showing revenue, cost breakdown, and net margin to attach to a loan application instead of verbal estimates.
- Owner comparing commercial vs. residential job mix — Runs the calculator with commercial job values ($800 average) versus residential ($350 average) at the same weekly volume and sees the margin difference — $28,000 versus $15,000 in monthly gross.
Key terms
- Materials/Parts cost percentage
- The blended percentage of gross revenue spent on electrical supplies, parts, and materials. Varies significantly by job type and is the primary variable cost in electrical work.
- Profit per job
- Total monthly net profit divided by total jobs completed in that month. A quick benchmark for operational efficiency and pricing adequacy.
- Pricing impact analysis
- A scenario table showing monthly profit at different average job values while holding all other costs constant — used to find the minimum rate for a target margin.
- Fixed overhead
- Monthly costs independent of job volume — licensing, insurance not tied to vehicles, office, software, and marketing spend.
Frequently asked questions
What is a realistic materials cost percentage for electrical work?
It depends heavily on your job mix. Service calls and troubleshooting run at 5–15% materials. Rough-in and panel work can hit 30–40%. A typical residential service company running a mix of call types might average 18–26% blended materials cost. Pull your actual supply house receipts against invoiced revenue for three months to get your real number.
Should I include subcontractor costs in labor or materials?
Subcontractor costs are best entered in Monthly Labor Cost since they function like variable labor — they scale with the work. If you use subcontractors only occasionally, you can adjust the labor input month to month to reflect the actual expenditure.
What profit margin should an electrical contractor target?
For a solo or small shop doing residential and commercial service work, 15–25% net margin is a common healthy range. Larger commercial contractors with higher overhead but higher volume sometimes operate at 8–12% net. Below 12% on a service-focused operation suggests either pricing is too low or overhead is too high for the volume.
How do I account for seasonality — slow winters or slow summers?
Run the calculator separately for your peak and slow months. The difference in net profit tells you the seasonal range, which informs how much cash buffer to hold and whether to adjust staffing between seasons. Entering an average of both in one run will give you a useful annual projection but will mask the lean months.
What does Profit Per Job tell me that the margin percentage does not?
Profit per job tells you how much you net on a single ticket, which matters when you are deciding whether to take a low-value call that still fills a slot in the schedule. If your profit per job is $80 and a $200 service call generates $20 after materials but no meaningful overhead allocation, it may still be worth doing on a slow day — or it may not. The per-job figure makes that decision concrete.
