Which expenses stay fixed and which move with sales for an ESD flooring contractor?

Cost classification

Break-even is only useful if stable overhead, job-linked spend, and staffing step-ups are separated. Here’s the quick math logic: fixed items set the monthly hurdle, while variable percentages protect margin as revenue grows.

Expense	Cost	Break-Even Treatment	Common Mistake
Warehouse and Office Rent	Fixed	Include $6,500/month in base overhead for every operating month.	Allocating rent only to awarded jobs.
Professional Liability Insurance	Fixed	Include $1,200/month before job-level margin is calculated.	Treating insurance like project labor.
Utilities and Communications	Semi-variable	Start with the $850/month baseline, then add usage pressure as shop activity rises.	Modeling the full amount as purely sales-driven.
Equipment Calibration Services	Fixed	Include $500/month from Month 1, even before testing volume ramps.	Adding calibration only after revenue starts.
Direct Installation Materials	Variable	Use 18% of first-year revenue, then apply the forecast percentage by year.	Spreading materials as flat monthly overhead.
Grounding Components and Consumables	Variable	Use 4% of revenue in the first year as a job-linked input.	Burying grounding supplies in general shop expense.
Project Specific Logistics and Travel	Variable	Use 4% of first-year revenue because travel rises with awarded work.	Leaving job travel in fixed overhead.
Operating Payroll	Semi-fixed	Model salaries by role and FTE step-ups, including added technicians after Month 13.	Treating every payroll dollar as variable labor.

How does break-even shift across lean, base, and full project loads?

Scenario table

Break-even gets safer as revenue climbs and fixed costs spread over more work. The lean case sits near the line, the base case covers overhead comfortably, and the full case creates the biggest cushion.

Planning assumptions only; actual results will shift with awarded project size, prep burden, and crew use.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean breakeven load	$64k	$19k	$41k	70%	$4k	Very thin cushion; one weak month can erase it.
Base year one mix	$449k	$135k	$41k	70%	$273k	Overhead is covered and profit is solid.
Full year five mix	$1.98M	$499k	$82k	74.8%	$1.40M	Wide cushion; fixed costs are well absorbed.

What breaks the break-even plan for this flooring contractor?

Stress test

Break-even sits near $640,000 a month on the base plan, so there is no cushion. A 20% revenue miss, a 15% fixed-cost jump, or a rise in variable expense from 30% to 35% can wipe it out fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$640,000	$0 cushion	No cushion; any miss turns negative.
Revenue shortfall	Revenue falls 20% to $512,000.	$640,000	$128,000 gap	A 20% miss leaves about $90,000 short in contribution.
Fixed-cost pressure	Monthly fixed costs rise 15% to about $515,000.	$735,000	$95,000 gap	More overhead wipes out the buffer fast.
Margin pressure	Variable expense rises from 30% to 35%.	$689,000	$49,000 gap	Small direct-cost slippage lifts break-even hard.
Combined pressure	Fixed costs rise 15% and variable expense hits 35%.	$793,000	$153,000 gap	The cushion disappears if both cost lines move against you.

What should this founder prove before signing the lease, hiring installers, and buying equipment?

Founder checklist

Don't sign the lease or add installers until awarded work can cover the monthly fixed load and the Month 2 cash dip. This model breaks even by Month 3, but the pipeline has to be real.

1Booked Work$449K/mo

Year 1 revenue is $5.39M, or about $449K a month, so only lock in space if that level is backed by awarded work.

2Fixed Load$41.0K/mo

The model carries about $10.1K of non-payroll fixed costs and $371K of Year 1 payroll, or roughly $41.0K a month, so fixed spend has to stay covered before you hire.

3Margin Floor70.0% CM

Direct installation materials at 18%, grounding consumables at 4%, logistics at 4%, and sales commissions at 4% leave a 70.0% contribution margin, so pricing needs to protect that floor.

4Crew Ramp4.5 FTE

Year 1 staffing is 4.5 FTE, then it grows to 6.0 FTE in Year 2, so the backlog has to keep the first crew busy before you add installers.

5Bid Flow100 wins

A $45K Year 1 marketing budget at a $450 CAC implies about 100 wins, so hold launch spend until that flow is tied to real bids and the $126K capex plan.

6Cash Cushion$797K

Cash bottoms at $797K in Month 2, so keep that reserve untouched while you absorb equipment, hiring, and ramp costs.
