Cost classification

Break-even gets more reliable when fixed overhead stays separate from job-level spending. In the first operating year, recurring overhead and $322K payroll set the monthly hurdle, while parts, fuel, software, and marketing move with service volume.

Expense	Cost	Break-Even Treatment	Common Mistake
Warehouse and office rent	Fixed	Include $4,500 per month as baseline overhead before job margin.	Treating rent as tied to each repair call.
General liability insurance	Fixed	Include $850 per month across the planning range.	Dropping it from break-even because it is not job-specific.
Payroll by staffing level	Semi-fixed	Model first-year wages at $322K per year, or about $26.8K per month, then step up when headcount increases.	Spreading payroll as a flat percentage of revenue.
Hardware and replacement parts	Variable	Apply 18.0% of revenue in the first year as direct job input.	Classifying springs, tracks, rollers, and openers as fixed overhead.
Direct consumables and fasteners	Variable	Apply 4.0% of revenue in the first year for job supplies.	Ignoring small items because each invoice amount looks minor.
Fuel and vehicle maintenance	Variable	Apply 6.0% of revenue in the first year as service volume rises.	Using one flat monthly amount even as route count changes.
Field service software fees	Variable	Apply 2.0% of revenue in the first year based on usage-linked activity.	Treating all software as fixed when fees scale with jobs.
Marketing budget and customer acquisition	Semi-variable	Plan $45K in first-year spend, then test against $125 customer acquisition cost.	Counting van purchases as monthly break-even expense instead of launch capital spend.

How does break-even shift from lean to full garage door service operations?

Scenario table

The model reaches break-even in Month 7 and payback in Month 20. Before that, fixed overhead drives the gap, so the move from lean to full changes risk more than it changes the break-even floor.

Planning assumptions only; actual results can differ.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$71K/mo	$21K/mo	$395K/mo	70%	-$345K/mo	Still below break-even; early revenue does not cover overhead.
Base operating case	$135K/mo	$39K/mo	$490K/mo	71%	-$394K/mo	Better margin, but cash burn stays high until volume catches up.
Full scale case	$312K/mo	$78K/mo	$904K/mo	75%	-$670K/mo	Highest cushion on sales mix, yet overhead still keeps it under break-even.

What pushes the garage door repair break-even plan into the red?

Stress test

The plan is most exposed to booking softness and small cost creep. At a 70% contribution margin, meaning 70% of revenue is left after direct costs, a 21% revenue drop wipes out the $149K cushion, and each extra $1K of monthly overhead adds about $14K of required revenue.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$565K	$149K cushion	Steady booking keeps the plan above water.
Revenue shortfall	Revenue falls 21% from the base plan.	$565K	$1K gap	The cushion disappears once booking slips past 21%.
Fixed-cost increase	Monthly overhead rises by $1K.	$579K	$135K cushion	Small overhead creep quickly raises the revenue bar.
Margin pressure	Job-level expenses rise 1 point, cutting contribution margin to 69%.	$573K	$141K cushion	Fuel and parts above the 30% variable base push break-even up.
Combined pressure	Revenue falls 21%, overhead rises $1K, and margin falls 1 point.	$593K	$29K gap	CAC above $125 and weaker bookings can flip the plan negative.

Can this garage door repair service hit break-even before you lock in the fleet, rent, and first hires?

Founder checklist

Do not sign the lease or buy the vans until local demand can carry the model’s Year 1 run rate and the Month 7 break-even target. The hard test is simple: enough booked work to cover the $322K payroll, $45K marketing plan, and the $663K cash trough in Month 2.

1Demand proof$857K Y1

Verify your call volume and booked jobs can support the first-year revenue run rate before you commit to vans, rent, and dispatch.

2Fixed load$35.8K/mo

Check that monthly revenue can cover rent, insurance, admin, software, and Year 1 payroll before you add more techs or overhead.

3Margin check70% CM

Hold parts, fuel, and software near the model’s 30% variable cost so hardware stays at 18% of revenue and break-even does not slip.

4Staffing ramp5 FTE Y1

Confirm this crew can handle the 45% emergency mix, 6-hour installs, and 1.5-hour maintenance calls without overtime or missed callbacks.

5Cash buffer$663K trough

Keep enough cash to survive the Month 2 low point, because capex and launch spend hit before the business reaches payback.

6Dispatch mix45% emergency

Set dispatch rules now so emergency repairs stay near the Year 1 mix, since that work type anchors early revenue and helps reach break-even faster.
