Which plant expenses are fixed and which move with sales?

Cost classification

Break-even is reliable only when each expense sits in the right bucket. Materials, unit labor, freight, and commissions move with volume; lease costs stay fixed, and utilities or maintenance need mixed treatment.

Expense	Cost	Break-Even Treatment	Common Mistake
Steel Coil Raw Stock	Variable	Include as a per-unit material charge in contribution margin.	Moving steel purchases into fixed overhead and overstating break-even margin.
Precision Fabrication Labor	Variable	Treat as unit-linked labor when scheduled by production volume.	Classifying all shop labor as fixed payroll regardless of output.
Facility Power	Semi-variable	Model the usage-linked portion at 0.8% of revenue for break-even.	Treating all power as rent-like fixed overhead.
Equipment Maintenance	Semi-variable	Use 0.8% of revenue until actual service history supports a tighter split.	Ignoring maintenance until a repair bill hits cash flow.
Manufacturing Facility Lease	Fixed	Include $45,000 per month in fixed overhead.	Allocating the lease only to units sold and hiding idle capacity.
Marketing and Trade Shows	Semi-fixed	Hold at $8,500 per month until expansion adds another campaign or show cycle.	Modeling trade shows as a smooth percentage of every sale.
Freight and Logistics	Variable	Apply 6.5% of revenue in the first year, then step down per the model.	Treating freight as fixed overhead instead of shipment-linked expense.
Sales Commissions	Variable	Apply 3.0% of revenue across the modeled years.	Classifying commissions as fixed overhead and understating volume risk.

How does break-even change from lean to full production?

Scenario table

Break-even rises as the plant scales, but the bigger driver is fixed payroll, not product price. More volume spreads lease and equipment costs, yet added engineers, sales reps, and quality control staff keep pushing the break-even bar higher.

Planning case only; actual break-even will move with mix, freight, and payroll.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean ramp case	$2.73M	$1.08M	$145K	60.4%	$1.51M	Month 1 break-even holds at about $240K monthly revenue.
Base Year 3 mix	$4.77M	$1.82M	$183K	61.8%	$2.76M	Break-even moves to about $296K monthly as payroll rises.
Full Year 5 throughput	$6.98M	$2.58M	$215K	63.1%	$4.19M	Higher throughput absorbs overhead, but break-even still edges up to about $341K.

What breaks the break-even plan for a cold-formed steel plant?

Stress test

Break-even looks safe in the base case, but the buffer can shrink fast if orders slip and steel, freight, or labor costs move up. The plant’s main risk is not launch month break-even; it’s keeping margin above fixed overhead as volume mix shifts.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$240K	$2.49M cushion	Base case clears break-even by about $2.49M.
Revenue shortfall	Monthly revenue falls 20% to $2.19M; costs stay flat.	$240K	$1.95M cushion	A 20% miss still clears break-even, but the cushion thins.
Fixed-cost increase	Add $10K/month of lease, equipment, or admin overhead.	$256K	$2.48M cushion	An extra $10K/month of overhead cuts the buffer.
Margin pressure	Contribution margin slips from 60.4% to 55.0%.	$263K	$2.47M cushion	Steel, freight, and labor creep move break-even up fast.
Combined pressure	Revenue falls 20%, fixed overhead rises $10K/month, and margin slips to 55.0%.	$281K	$1.91M cushion	Small hits stack fast when volume and margin both slip.

What should you verify before you sign the lease and order the main line?

Founder checklist

Don’t sign the lease or order the main line until first-year demand, site fit, and supplier quotes all support the Month 1 break-even case. Here’s the quick math: the model still needs $710K minimum cash in Month 1, so launch readiness has to come before the full revenue ramp.

1Demand proof2.27M units

Verify signed or near-signed Year 1 orders for 1.2M studs, 400K tracks, 150K joists, 20K trusses, and 500K clips before you count on break-even volume.

2Site fit$45K/mo

Check floor space, zoning, loading bays, power, water, and security before you lock the $45K monthly lease, because a bad site can block output.

3Steel quotes$0.35-$28.00

Get firm steel quotes across the SKU mix and test them against unit input costs from $0.35 to $28.00, so margin survives at launch.

4Equipment timing$1.55M

Confirm lead times and install dates for the $850K roll forming line, $420K truss station, and $280K cutting systems, or revenue starts late.

5Payroll load$715K/yr

Staff the Year 1 salaried load of $715K, including the plant manager, two structural engineers, the sales director, three reps, and one QC tech.

6Cash cushion$710K

Hold at least $710K of cash for Month 1 and test freight lanes before you assume 65% of revenue, because shipping delays can stall collections.
