Which expenses are fixed and which move with sales in a living wall installation business?

Cost classification

Break-even is only useful if each expense behaves the way the model says it does. Here, job-linked materials and subcontractors move with revenue, while rent, insurance, fleet, software, and payroll set the monthly hurdle.

Expense	Cost	Break-Even Treatment	Common Mistake
Plants and Growing Materials	Variable	Model at 18.0% of first-year revenue, improving to 14.0% by the fifth year as sourcing and waste control improve.	Underpricing replacements, plant loss, and spoilage.
Hardware and Irrigation Systems	Variable	Model at 8.5% of first-year revenue, falling to 6.5% by the fifth year as purchasing scale improves.	Forgetting brackets, pumps, sensors, and controls.
Installation Subcontractors	Variable	Model at 12.0% of first-year revenue, declining to 7.5% by the fifth year as internal crews absorb more work.	Burying overtime and rush labor in gross margin.
Sales Commissions and Travel	Variable	Model at 5.5% of first-year revenue, easing to 3.5% by the fifth year as referrals and route density improve.	Treating site visits and proposal trips as free.
Office and Warehouse Rent	Fixed	Use $8,500 per month from Month 1 through Month 60, regardless of short-term job volume.	Signing for space before install routes are proven.
Vehicle Fleet and Fuel	Semi-fixed	Use $4,200 per month, then step up only when more routes, vans, or crews are needed.	Adding vehicles before install density supports them.
Utilities and Communications	Semi-variable	Start with the $1,200 monthly base, but watch usage as irrigation testing, storage, and field communication increase.	Letting testing, water, and storage utilities creep up.
Payroll	Semi-fixed	First-year wages run about $38,300 per month, based on $459,500 annual staffed payroll, and rise in steps as headcount grows.	Hiring ahead of signed backlog and crew utilization.

How does break-even change from a lean ramp to a full living wall buildout?

Scenario table

Higher revenue cases spread the same fixed overhead across more work, so the break-even line moves fast. At a 56% contribution margin, the full case covers overhead, the base case is still tight, and the lean case stays below cover.

Scenario figures are planning assumptions, not guarantees; use them to test volume, margin, and overhead, not to promise results.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean ramp-up case	$90k	$475k	$884k	56%	-$279k	Still below break-even; ramp needs more volume.
Base launch case	$121k	$639k	$884k	56%	-$71k	Very close, but still a small operating gap.
Full Year 1 average case	$211k	$1.1M	$884k	56%	$536k	Covers break-even and leaves a solid cushion.

What breaks the break-even plan if sales slow or costs creep up?

Stress test

The base plan breaks even at about $1.21M in annual revenue with a 56% contribution margin, meaning 56 cents of each sales dollar covers fixed costs, and $677k of fixed overhead. A 20% sales miss or a 5-point margin drop creates a six-figure gap fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$1.21M	$0 gap	No cushion until installs stay steady.
Revenue shortfall	Annual revenue runs 20% below break-even, to about $968k.	$1.21M	$135k gap	Delayed installs and weak close rates hit cash first.
Fixed-cost pressure	Fixed overhead rises 10% to about $745k a year.	$1.33M	$121k gap	Rent, fleet, and staffing creep raise the bar before scale.
Margin pressure	Variable costs rise from 44% to 49%, cutting contribution margin to 51%.	$1.33M	$119k gap	Subcontractor overtime and plant loss squeeze contribution.
Combined pressure	Revenue falls 20% below break-even, fixed overhead rises 10%, and variable costs climb to 49%.	$1.46M	$251k gap	Too much territory before route density builds widens the hole.

Can you commit to the warehouse, fleet, and crew without breaking the Month 5 path to break-even?

Founder checklist

Don’t lock the warehouse, fleet, and full crew until the Month 5 break-even path still holds. The real test is whether $75K in Year 1 marketing can feed 9 blended jobs a month without breaking the $23.2K fixed load and $350K cash cushion.

1Demand Proof$75K / $2.5K CAC

Verify that Year 1 marketing can hold customer acquisition cost (CAC) near $2.5K and keep 9 blended jobs a month coming in, or keep the territory tight.

2Fixed Load$23.2K/mo

Check that rent, vehicles, insurance, software, utilities, professional help, supplies, and events stay near this fixed base before you sign the warehouse and fleet.

3Margin Check56% CM

Use the Year 1 mix to confirm plants, hardware, subcontractors, and travel still leave about 56% contribution margin after direct costs.

4Supply Lock18% + 8.5%

Lock plant and irrigation suppliers before taking large deposits, because Year 1 assumes 18% for plants and growing materials and 8.5% for hardware.

5Crew Capacity5.5 FTE

Keep hiring at the modeled crew level until subcontractors can cover peaks, since Year 1 already uses 5.5 full-time equivalents and more hires start later.

6Cash Cushion$350K

Hold this reserve through the $563K launch capex, because cash bottoms out in Month 5 and break-even is not the same as liquidity.
