Cost classification

Break-even is only useful if fixed overhead and job costs stay in their lanes. This model reaches break-even in Month 9, so misclassifying 18.0% materials or about $22,300/month first-year payroll can move the target fast.

Expense	Cost	Break-Even Treatment	Common Mistake
Office/Warehouse Rent	Fixed	Use $2,500/month in fixed overhead from Month 1 through Month 60.	Treating rent as a job-level expense.
Vehicle Leases/Payments	Fixed	Use $1,800/month as capacity overhead before job-level fuel and maintenance.	Mixing lease payments with trip fuel.
Year 1 Payroll	Semi-fixed	Use about $22,300/month in the first year, then step up as electrician and admin FTEs increase.	Ignoring owner pay in monthly fixed payroll.
Annual Marketing Budget	Fixed	Spread $15,000/year as about $1,250/month in first-year demand generation.	Treating committed budget as CAC on each job.
Electrical Materials & Parts	Variable	Apply 18.0% of revenue in the first year; this is direct job consumption.	Treating project materials as overhead.
Subcontractor Labor Project-Specific	Variable	Apply 3.0% of revenue in the first year when outside labor is tied to jobs.	Budgeting project subcontractors as standing payroll.
Fleet Fuel & Maintenance Project-Related	Variable	Apply 4.0% of revenue in the first year for job-linked trips and service use.	Burying route-driven spend in fixed vehicle costs.
Project-Specific Permits & Fees	Variable	Apply 2.0% of revenue in the first year when jobs require permits or local fees.	Forgetting permit-heavy jobs reduce contribution margin.

How does break-even change from a lean launch to a full multi-crew electrical contractor?

Scenario table

Here’s the quick math: as the contractor adds crews, marketing, and overhead, break-even revenue climbs from about $407K to about $1.04M a month. Margin stays strong, but only if billed hours keep pace.

Planning assumptions only; actual break-even moves with crew mix, pricing, and job size.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch: residential and small commercial	$407K	$110K	$297K	73%	$0	Early work breaks even only if crews stay highly utilized.
Base scale-up: larger crew and marketing	$770K	$191K	$579K	75.2%	$0	This is the first steady scale point, but overhead is still tight.
Full buildout: multi-crew commercial and smart home	$1.04M	$228K	$808K	78%	$0	More volume can support growth, but idle time quickly eats the cushion.

What breaks the break-even plan for an electrical contractor?

Stress test

Base break-even is about $407K a month against roughly $297K in fixed monthly costs. Slower jobs, higher overhead, and margin squeeze from materials, labor, and truck repairs are the main risks.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change to the base case.	$407K	$0 gap	The model only clears the line at the base target.
Revenue shortfall	Monthly revenue falls 10% to about $367K.	$407K	$40K gap	Fewer service calls or delayed starts hit fast.
Fixed-cost increase	Fixed costs rise 10% from rent, insurance, or fleet spend.	$448K	$41K gap	Higher overhead pushes the floor up.
Margin pressure	Variable expenses rise to 320% and squeeze contribution margin.	$437K	$30K gap	Material price jumps and overtime eat the cushion.
Combined pressure	Revenue falls 10%, fixed costs rise 10%, and variable expenses rise to 320%.	$445K	$78K gap	Slow work, higher overhead, and squeezed margins turn break-even into a loss.

What should an electrical contractor prove before signing the lease, hiring the next tech, or buying another van?

Founder checklist

Before you lock in more space, a second vehicle, or more hires, prove Year 1 demand can carry the fixed load and still leave cash after a slow ramp. In this model, break-even only holds if bookings, crew hours, and acquisition cost stay near plan.

1Demand Proof$407K/mo

Verify service area demand can support at least $407K in monthly Year 1 revenue before you add fixed costs.

2Fixed Load$90K/yr + $6.2K/mo

Make sure the $90K owner pay and the $6.2K monthly non-pay base are in the plan before you commit to rent or vehicles.

3Contribution73% CM

Check that materials, subcontractors, fuel, and permits stay near a 73% contribution margin so each job still helps cover overhead.

4Crew Ramp4.0 FTE

Confirm the Year 1 crew of 4.0 FTE can handle booked work without overtime spikes, because labor pressure can erase margin fast.

5Cash Cushion$697K by Month 16

Hold enough cash to survive the $80K Year 1 EBITDA loss and the Month 16 cash trough before you scale the business.

6Launch Spend$15K, $150 CAC

Keep Year 1 marketing at $15K and test whether CAC stays near $150 before adding another van or more hires.
