How This Calculator Works: The Formulas Behind Your Results

True job costing goes beyond just labor and materials. Your total direct cost per job includes labor (hours times your fully burdened rate), materials and parts, permits, subcontractor costs, and any other per-job expenses like equipment rental or truck stock. Your gross profit is what remains after subtracting all direct costs from your selling price.

But gross margin is only half the story. To find your real net margin, you need to subtract your monthly overhead — rent, truck payments, insurance, office staff, marketing, software — from your total gross profit. The number that is left over is what you actually take home.

For Electrical work, the typical job runs around $1,500 in revenue. At that ticket size with 3 labor hours at $38/hr burdened rate and $300 in materials, your direct cost is roughly 45-50% of revenue. The margin between direct cost and gross profit is where you absorb overhead and owner profit.

Service and repair calls run 62-70% margin, while panel upgrades and new construction jobs run 55-65% margin.

Direct Cost per Job

Direct costs are the expenses tied directly to executing a specific job:

• Field labor: 3 hours × $38/hr burdened = roughly $114 labor (varies by job complexity)
• Materials and parts: $300 average (parts, fixtures, supplies, waste)
• Subcontractor labor: if applicable, locked-in crew rates
• Permits and compliance: regulatory requirements
• Commissions: if you pay sales bonuses
• Equipment rental or consumables: per-job only

Add those up. That’s your direct cost. Subtract from revenue, and you have gross profit. That gross profit must cover overhead and owner profit.

Gross Profit and Gross Margin

Gross margin is your gross profit divided by revenue, expressed as a percentage. Most profitable electrical companies run 55-65% blended gross margins. Below 45%, and you’re likely to struggle with profitability after overhead.

Benchmark:

• 55-65% blended gross margin is the target for sustainable, growing electrical firms
• Below 45%: pricing or cost efficiency is hurting profitability
• Above 60%: either your costs are low, or you’re in a premium position

Use this calculator to stress-test your costs. If you’re hovering at 48% gross margin on a $1,500 ticket, a 2-3% price increase or a 30-minute labor efficiency gain moves you to 50-52%. That’s $300-$500 per job—multiplied by 140 jobs, it’s $4,500-$8,000 extra monthly profit.

Breakeven and Net Margin Targets

Breakeven is the monthly revenue (or job count) you need to cover your fixed overhead and earn zero net profit. Your electrical company carries roughly $42,000 in monthly overhead—rent, insurance, truck payments, office staff, software, owner salary.

At 55-65% blended gross margin and $1,500 average ticket, you need roughly 46 jobs per month just to break even. Most healthy electrical companies run 120-180% of breakeven volume, meaning 140 jobs per month nets you 2-3x breakeven profit.

Here’s the math:

• Breakeven volume: 46 jobs/month
• Your typical volume: 140 jobs/month
• Excess volume beyond breakeven: 94 jobs/month
• At 55-65% blended gross margin per excess job: $780 gross profit per excess job
• Monthly net profit: $73,320 (before owner tax)

If you’re below breakeven volume, your business is bleeding cash. If you’re at 1.5x breakeven, you have room to invest in growth, improve margins, or increase owner distributions.

Monthly Scenario Analysis

Use the calculator to run “what-if” scenarios:

• Pricing pressure: What if you drop your price by 5%? Gross profit per job drops by $75. You’d need 2-3 extra jobs just to stay even. Often, pricing is the wrong lever—focus on labor and materials first.
• Labor efficiency: What if you trim 30 minutes off each job? Direct cost drops by $19.0 (assuming $38/hr burdened). Gross margin jumps by roughly $30 per job—often the fastest margin gain.
• Overhead control: What if you cut overhead by $5,000/month (tighter spending, renegotiated contracts)? Your breakeven jobs drops from 46 to 43. Suddenly, that slow month doesn’t hurt as badly.
• Volume growth: At 140 jobs/month, you need 46 just to survive. Every job above that is nearly pure profit (after direct costs). If you can add 5-10 jobs/month through better sales or referrals, net profit jumps by $23,000-$46,000 monthly (rough estimate).

Most electrical companies we work with find the fastest margin gains by addressing labor efficiency first, then repricing underperforming job types, then overhead consolidation. The calculator helps you quantify the impact of each lever.

Frequently asked questions about electrical job costing

How do electrical service and new construction margins differ?

Service calls and emergency repairs run 62-70% gross margins—quick, high-touch, minimal materials. Panel upgrades and new construction work is lower at 55-65% due to higher material costs and more complex labor. Most successful shops blend these at 55-65%.

What is the true cost of licensing and continuing education?

Master electrician licensing, apprentice supervision, and continuing education (required every 3 years) typically cost $2,000-$4,000 per year across the team. This is overhead—allocate it monthly and price it into your service rates.

What’s the economics of a panel upgrade job?

Panel upgrades run $3,000-$8,000 depending on amp service. Materials (panel, breakers, wire) are 35-45% of the ticket. Labor is 40-50%. If you’re running below 45% gross margin on panel work, repricing or labor efficiency gains will add $500-$1,000 per job.

How many jobs per month does an electrical company need?

With $42k monthly overhead and a $1,500 average ticket at 52% gross margin, you need roughly 46 jobs to break even. At 140 jobs/month (your typical volume), you’re clearing about $42k in monthly net profit—if your labor and material costs stay in line.

How does my job costing calculator match my P&L?

The calculator shows gross margin per job. Your P&L shows net margin after overhead. If the calculator shows 52% gross but your P&L shows 10% net, your overhead is eating 42% of revenue. Run both monthly—they should align closely.

What’s the best way to improve electrical margins?

Start with labor efficiency—fewer hours per job through better planning and tech training. Then repricing (many shops underprice service calls and panel work). Finally, tackle overhead consolidation (software, insurance, office staff). Most shops gain 3-5 margin points from labor alone.
