Cost classification

Break-even is reliable only if job-linked costs move with revenue and monthly overhead stays fixed. In this model, the split matters because break-even lands in Month 6 with $669k minimum cash need.

Expense	Cost	Break-Even Treatment	Common Mistake
Equipment and hardware procurement	Variable	Model at 18.0% of revenue in the first year, falling to 16.0% by Year 5.	Treating pass-through equipment as full margin.
Direct installation materials	Variable	Apply 4.0% of revenue in the first year, declining to 3.0% by Year 5.	Burying job materials inside overhead.
Fuel and vehicle maintenance	Variable	Use 3.0% of revenue in the first year, improving to 2.2% by Year 5.	Ignoring route density and drive time.
Sales commissions	Variable	Keep at 5.0% of revenue in each forecast year.	Modeling commissions as fixed payroll.
Showroom and office lease	Fixed	Include $4,500 per month from Month 1 through Month 60.	Signing before lead flow is proven.
Liability and workers comp insurance	Fixed	Include $1,800 per month as launch overhead.	Excluding required insurance from break-even.
Utilities and internet	Semi-variable	Start with the $650 monthly baseline, then review as showroom use grows.	Assuming no change with operating activity.
Salaried team	Semi-fixed	Use about $24.7k per month in the first year, then step up with added staff.	Hiring ahead of the install backlog.

How does break-even shift from lean to base to full installation volume?

Scenario table

Lean is near the line, base clears it with a solid cushion, and full capacity gives the widest buffer. The main driver is mix: more residential elevator work lifts revenue faster than fixed overhead.

Planning assumptions only; actual break-even will move with project mix, close rates, and install timing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean ramp-up mix	$77.4k	$23.2k	$36.3k	70.0%	$17.9k	Positive, but delays can erase the cushion.
Base pipeline mix	$152.9k	$44.5k	$41.8k	70.9%	$66.6k	Healthy margin once Month 6 is reached.
Full scaled-crew mix	$370.6k	$97.1k	$66.8k	73.8%	$206.7k	Strongest cushion if higher-value jobs stay full.

What breaks the break-even plan for a home elevator installer?

Stress test

Here’s the quick math: at about $363K annual fixed overhead and a 70% contribution margin, break-even is about $518K. Year 1 revenue of $929K leaves about $411K of cushion, but permit delays, slow conversion, and callback labor are the first risks.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$518K	$411K cushion	Healthy cushion, but only if booked work starts on time.
Revenue shortfall	Year 1 revenue falls 25% to about $697K.	$518K	$179K cushion	Slow conversion cuts the cushion fast.
Fixed-cost increase	Fixed overhead rises 10% to about $399K.	$570K	$359K cushion	Lease, insurance, or showroom creep lifts the bar.
Margin pressure	Contribution margin drops 5 points to 65%.	$559K	$370K cushion	Supplier price hikes and callback labor squeeze spread.
Combined pressure	Revenue falls 20%, fixed overhead rises 15%, and margin drops to 65%.	$642K	$101K cushion	The cushion is thin, so one more miss can turn cash tight.

Can you prove this home elevator business will hit break-even before you sign the showroom lease and buy the vans?

Founder checklist

Don’t sign the showroom lease or buy the vans until the model shows at least $52K in monthly revenue and a $669K cash floor by Month 6. Then confirm the $45K Year 1 marketing plan can support a roughly $850 CAC, plus a 70% contribution margin and staffing that scales with job hours.

1Demand Path$52K/mo

Verify booked quotes and install demand can support at least $52K a month before you lock the showroom lease and open heavy spend.

2Marketing Funnel$850 CAC

Check that the $45K Year 1 marketing plan can keep customer acquisition cost near $850, or lead flow will miss the launch target.

3Fixed Load$11.6K/mo

Confirm the fixed base stays near $11.6K a month, because lease, insurance, software, and ads start hitting before installs do.

4Margin Mix70% CM

Verify equipment, materials, fuel, and sales commissions leave about 70% contribution margin, and that supplier terms do not squeeze cash too early.

5Staffing Ramp4.5 FTE

Check that the Year 1 team can cover 4.5 FTE and still hire against backlog, since payroll grows before revenue fully matures.

6Cash Reserve$669K

Keep at least $669K of cash through Month 6, because that is the model’s low point and payback does not come until Month 18.
