Which stretch ceiling installation expenses are fixed, and which move with sales?

Cost classification

Break-even is only useful if project costs move with revenue while monthly overhead stays fixed. Mix those up, and the Month 6 break-even point can look safer than it really is.

Expense	Cost	Break-Even Treatment	Common Mistake
Warehouse/Showroom Rent	Fixed	$3,500 monthly overhead from Month 1 through Month 60.	Treating rent as a job-level charge.
Installation Materials	Variable	19% of revenue in the first year.	Ignoring waste and rework in material use.
Integrated Component Costs	Variable	4% of revenue in the first year.	Burying specialty parts inside general supplies.
Project-Specific Subcontractors	Variable	3% of revenue in the first year.	Treating outside labor like fixed payroll.
Project Equipment & Logistics	Semi-variable	2% of revenue in the first year for project travel, setup, and equipment use.	Missing travel and setup swings by job type.
Vehicle Fleet Insurance & Maintenance	Semi-fixed	$1,200 monthly base tied to keeping the installation van operating.	Assuming every mile scales cleanly with sales.
Software Subscriptions	Fixed	$600 monthly overhead for CRM, project management, and accounting tools.	Assigning the same subscription fee to each job.
Field and Operations Payroll	Semi-fixed	$200,000 annually in the first year, or about $16,667 monthly.	Forgetting paid idle time between installations.

How does break-even change from lean to base to full utilization in stretch ceiling installation?

Scenario table

Break-even sits at the base case. At 75% of that level, the business is about $66K short each month; at 125%, it builds about a $66K cushion, assuming the 72% contribution margin holds.

Planning cases only: these figures show how break-even moves with utilization, so they are not guarantees.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean utilization case	$275K	$77K	$264K	72%	-$66K	Below break-even, so cash stays under pressure.
Base break-even case	$367K	$103K	$264K	72%	$0	At break-even, so fixed costs are fully covered.
Full-capacity planning case	$458K	$128K	$264K	72%	$66K	Above break-even, so the business has a cushion.

What breaks the break-even plan for stretch ceiling installation?

Stress test

At 72% contribution, break-even is about $367,000 against $264,000 of fixed overhead. That leaves no cushion, so discounting, rework, overtime, slow quote-to-close flow, and supplier waste can push the plan into a gap.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	Base margin and overhead hold.	$367,000	$0 cushion	There is no room for slippage.
Revenue shortfall	Revenue lands 10% below plan.	$367,000	$36,700 gap	A small booking miss quickly turns into a loss.
Fixed-cost pressure	Annual fixed overhead rises by $10,000.	$380,600	$13,900 gap	Overhead creep pushes break-even higher fast.
Margin pressure	Variable expenses rise 1 point to 29% of revenue.	$371,800	$5,200 gap	Small waste, rework, or overtime eats the cushion.
Combined pressure	Revenue is 10% light, overhead rises $10,000, and variable expenses rise 1 point.	$385,900	$55,900 gap	Separate misses stack into a material gap.

What has to be true before you sign the showroom lease and hire the first crew?

Founder checklist

At the Year 1 mix, each project averages about $2.1K in revenue and about 67% contribution, so break-even sits near 17 projects a month. Don’t sign the lease or add payroll until you can also fund the $125K startup capex and hold the Month 2 cash floor of $813K.

1Project Volume18/mo

Verify you can book at least 18 projects a month before you scale overhead, because the Year 1 mix only works if real demand matches the staffing plan.

2CAC Capacity50/yr

Check that a $25K Year 1 marketing budget at $500 CAC can really buy enough paid customers, or the pipeline will never reach break-even speed.

3Fixed Load$24.3K/mo

Keep the full fixed load close to this level, including the $3,500 showroom rent, because break-even revenue has to cover that burn every month.

4Contribution67% CM

Use the Year 1 mix only if installed material, components, subcontractors, and logistics stay near 33% of revenue, or each job pays less than the model says.

5Crew Hours387 hrs/mo

Track weekly booked hours and only add payroll against booked work, since 18 projects a month is about 387 billable hours at the current mix.

6Cash Buffer$813K

Hold this reserve through the Month 2 cash dip, cover the $125K startup capex, and confirm supplier lead times before taking deposits.
