Cost classification

Break-even gets unreliable when plant overhead, batch inputs, and volume charges are blended together. Model unit-linked items by product, then keep true monthly obligations like the $75,000 facility lease separate.

Expense	Cost	Break-Even Treatment	Common Mistake
Raw Materials Sulfur, Salt, Brine, Natural Gas, and Ethylene	Variable	Apply per-unit COGS by product: $120, $150, $200, $250, and $400 per unit.	Using one blended materials rate across all chemicals.
Energy Consumption, Electrolysis, Synthesis, and Oxidation	Variable	Model energy by unit produced, from $70 per sulfuric acid unit to $250 per ethylene oxide unit.	Treating process energy as monthly plant overhead.
Direct Labor Production	Semi-fixed	Use per-unit labor only where output drives hours, but keep staffing floors for plant operators in payroll planning.	Assuming labor falls to zero when volume dips.
Quality Control Lab	Semi-variable	Scale with test volume; current model runs from 0.4% to 0.7% of product revenue.	Treating lab work as fully fixed at higher throughput.
Plant Utilities Overhead	Semi-variable	Split base load from production load; current model uses 0.7% to 1.0% of product revenue.	Holding utilities flat while production rises.
Environmental Compliance Admin	Semi-fixed	Keep a permit floor, then step up for higher operating activity; current model uses 0.2% to 0.4% of revenue.	Confusing permit minimums with activity-driven compliance work.
Facility Lease & Property Tax	Fixed	Carry $75,000 per month from Month 1 through Month 60 in break-even overhead.	Spreading lease expense per unit and hiding the cash floor.
Insurance Premiums	Fixed	Carry $12,000 per month from Month 1 through Month 60 unless the policy base changes.	Linking insurance to sales volume without policy support.

How does break-even change from lean to base to full output?

Scenario table

Lean output already clears fixed costs, but the cushion is thinnest at about $255K of monthly fixed cost. By Year 3 and Year 5, higher volume absorbs overhead better and lowers break-even risk.

Planning assumptions only, not guarantees; actual results will move with plant design, uptime, pricing, feedstock, and mix.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean start-up mix (Year 1)	$87.5M	$11.3M	$255K	87.1%	$76.0M	Well above break-even, but the cushion is narrowest here.
Base operating mix (Year 3)	$143.0M	$17.8M	$310K	87.5%	$124.9M	Overhead is absorbed better, so break-even risk falls.
Full run-rate mix (Year 5)	$202.3M	$24.5M	$365K	87.9%	$177.4M	Strongest cushion, but only if demand and feedstock stay steady.

What breaks first if revenue slips or plant costs run hot?

Stress test

Year 1 has a huge break-even cushion: about $875M monthly revenue against roughly $174M variable expense and $255K fixed cost. The real stress comes from slower offtake, a 5-point margin squeeze, or fixed plant overhead running 25% hot.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$318K/month	$874.7M cushion	Overhead is covered with room to spare.
Revenue shortfall	Revenue falls 20%; variable rates hold.	$318K/month	$699.7M cushion	Demand can drop hard before break-even is hit.
Fixed-cost pressure	Fixed overhead rises 25%.	$398K/month	$874.6M cushion	Plant overhead overruns move break-even, but not by much.
Margin pressure	Variable expenses rise 5 percentage points.	$340K/month	$874.7M cushion	Feedstock, logistics, or yield loss tightens the margin fast.
Combined pressure	Revenue falls 20%, variable costs rise 5 points, and fixed costs rise 25%.	$425K/month	$699.6M cushion	The model still clears overhead, but delayed offtake, utility spikes, missed batch yields, and compliance downtime are the warning signs.

What should you verify before signing the plant lease and ordering major equipment?

Founder checklist

Before you lock in the lease, equipment, or hiring, test the model against real buyers, plant readiness, and cash. The Year 1 plan only works if the opening run can support about $87.5M of average monthly revenue and you can carry the $10.239M cash floor from Month 1.

1Buyer pipeline$87.5M/mo

Verify signed or near-signed industrial buyers before you commit, because Year 1 revenue averages about $87.5M per month and the forecast needs real offtake, not hope.

2Fixed burn$255.4K/mo

Check the monthly fixed load from lease, insurance, compliance, R&D, IT, admin, safety, and payroll, because that burn starts before volume does.

3Unit margin80.1% CM

Confirm the Year 1 mix still clears about 80.1% contribution margin after unit COGS plus 3.0% sales commissions and 4.0% logistics, or the plant will struggle to fund overhead.

4Plant ramp285,000 units

Verify the site can support 100,000 sulfuric acid, 80,000 caustic soda, 50,000 chlorine gas, 40,000 ammonia, and 15,000 ethylene oxide units in Year 1, with sulfur, salt, brine, natural gas, ethylene, power, water, and gas lined up before the $4.0M utility build.

5Cash floor$10.239M

Keep the minimum cash need visible from Month 1, because the build burns cash before steady output and the model says the floor sits at $10.239M.

6Core crew14 FTE

Verify the opening team can cover operations, sales, compliance, and the plant floor from day one, because Year 1 assumes 14 full-time staff and missing safety or lab coverage slows ramp-up fast.
