Cost classification

Break-even is reliable only when overhead, job materials, labor capacity, and route costs are kept separate. If you treat every dollar as per-job spend, Month 7 break-even can look stronger than cash reality.

Expense	Cost	Break-Even Treatment	Common Mistake
Office and Warehouse Rent	Fixed	Carry as $4,500 per month overhead from Month 1 through Month 60.	Assigning rent to each repair job.
Business Insurance	Fixed	Carry as $2,200 per month overhead across the planning range.	Tying the full amount only to claims volume.
Vehicle Insurance	Fixed	Carry as $1,800 per month overhead, separate from route usage.	Confusing insurance with fuel and maintenance.
Auto Glass and Installation Materials	Variable	Model as 18.0% of revenue in the first year, falling to 16.0% by Year 5.	Treating stocked glass as free inventory.
Adhesives and Repair Resins	Variable	Model as 4.0% of revenue in the first year, falling to 3.2% by Year 5.	Ignoring resin use on chip repairs.
Vehicle Fuel and Maintenance	Semi-variable	Model as 5.5% of revenue in the first year, improving to 4.2% by Year 5 as route density improves.	Missing how drive time changes margin.
Payment Processing Fees	Variable	Model as 2.8% of revenue in the first year, falling to 2.4% by Year 5.	Excluding card volume from break-even.
Auto Glass Technician Salaries	Semi-fixed	Model as capacity added in hiring steps: 2.0 FTE in Year 1, rising to 6.0 FTE by Year 5.	Pricing jobs without labor coverage.

How does break-even shift from a lean launch to a full auto glass build?

Scenario table

Break-even climbs as staffing and marketing add fixed cost, even though the mix gets more efficient. Lean clears near $564k a month, base near $883k, and full near $1.26M.

Planning assumptions only; actual break-even will move with mix, pricing, and staffing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$564k	$171k	$393k	69.7%	$0	Lowest revenue floor, but a mix slip can erase cushion.
Base growth case	$883k	$247k	$636k	72.0%	$0	Better cushion from mix, though payroll still lifts the floor.
Full build case	$1.26M	$325k	$935k	74.2%	$0	Strongest margin, but the highest sales level is needed to clear overhead.

What breaks the break-even plan for an auto glass repair launch?

Stress test

Here’s the quick math: the base plan breaks even at $564k/month, but a 10% revenue miss leaves about a $39k monthly operating gap. If fixed commitments or material and rework costs climb, break-even moves to $607k-$620k fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$564k/mo	$0 gap	Delayed claim payments still strain cash.
Revenue shortfall	Revenue slips 10% to $507k/month.	$564k/mo	$39k gap	Weak route density or low demand shows up first.
Fixed-cost pressure	Fixed commitments rise 10% to $432k/month.	$620k/mo	$56k gap	Extra rent, labor, or lease load lifts the bar.
Margin pressure	Variable expenses rise from 303% to 353% of revenue.	$607k/mo	$43k gap	Supplier price hikes and warranty rework compress margin.
Combined pressure	Revenue drops 10% to $507k/month, fixed commitments rise 10% to $432k/month, and variable expenses rise to 353% of revenue.	$611k/mo	$104k gap	Low utilization plus delayed claims can tip the launch negative.

What should an auto glass repair founder verify before committing to the lease, vehicles, and equipment?

Founder checklist

Test the break-even load before you lock in space or headcount. The model needs about $564K a month in Year 1 revenue, so demand, pricing, and cash have to line up before the big spend.

1Demand proof$564K/mo

Verify booked work can hit the first-year break-even run rate before you lease space or hire more techs; at a $228 ticket, that means roughly 2,474 jobs a month.

2Launch demand$48K / $85

Check that $48K of Year 1 marketing at about $85 customer acquisition cost can fill the schedule fast enough, because idle tech time is dead cash.

3Margin check69.7% CM

Contribution margin, or the share left after direct job costs, should stay near 69.7% in Year 1: 22% materials plus 8.3% variable costs leaves room for fixed overhead.

4Fixed load$35.3K/mo

Make sure rent, insurance, software, vehicles, utilities, and the Year 1 wage plan fit under about $35.3K a month before variable costs; that is the baseline you must cover every month.

5Staffing rampMonth 7-25

Confirm the hire sequence and route radius both match volume: the customer service rep starts in Month 7, the ADAS specialist in Month 13, and the service area must stay inside the 5.5% fuel and maintenance load.

6Supply gate$25K + $45K

Secure glass and adhesive supply before the $25K inventory buy, prove advanced driver-assistance systems (ADAS) calibration demand before the $45K equipment spend, and keep cash above the Month 6 trough of $669K.
