Which steel plant expenses are fixed and which move with tons produced or sales?

Cost classification

Break-even is only useful if each expense follows its real behavior. For this plant, raw inputs move by ton, overhead moves partly with sales, and insurance and management stay fixed in the monthly planning range.

Expense	Cost	Break-Even Treatment	Common Mistake
Scrap Steel	Variable	Use the product-specific range of $38 to $50 per ton produced.	Burying raw material swings in overhead.
Electricity Direct	Variable	Apply $22 to $35 per ton based on the product run.	Mixing furnace power with Energy Overhead.
Alloying Agents	Variable	Model $8 to $100 per ton; AHSS Sheet carries the high end.	Missing margin compression when AHSS mix rises.
Direct Operating Labor	Variable	Use $14 to $30 per ton produced for line labor.	Combining hourly production labor with salaried staff.
Energy Overhead	Semi-variable	Apply 1.5% of revenue as plant-level energy load beyond direct electricity.	Double-counting direct electricity in overhead.
Plant Maintenance Overhead	Semi-variable	Use 1.2% of revenue to reflect wear tied to higher output.	Treating maintenance as flat while volume ramps.
Plant Insurance	Fixed	Include $150,000 per month from Month 1 through Month 60.	Scaling insurance with tons produced.
Plant Management	Fixed	Include the Plant Manager salary at $250,000 per year.	Loading salaried management into per-ton labor.

How does break-even change from a lean run to a full steel plant run?

Scenario table

Higher throughput spreads fixed plant costs across more tons, so profit rises as the run gets fuller. Even so, product mix and input costs still decide how much cushion is left.

Planning case values only; they are not guarantees and should be checked against live input prices, demand, and plant uptime.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean steel run	$30.3M	$6.4M	$0.6M	78.9%	$23.2M	Break-even is tight, so input spikes can erase cushion.
Base steel run	$53.9M	$10.6M	$0.7M	80.3%	$42.5M	Fixed overhead is covered well, with a healthier buffer.
Full steel run	$72.1M	$13.2M	$0.8M	81.6%	$58.1M	Highest cushion here, but mix and power costs still matter.

What breaks the break-even plan for this steel plant?

Stress test

The plant is far above break-even in the base case, but cash still turns negative in Month 9, with minimum cash around -$262.5M. If sales slide toward $0.79M or input costs rise, the safety margin disappears fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$0.79M	$29.46M cushion	Strong cushion, but cash still tightens by Month 9.
Revenue shortfall	Monthly sales fall 15%.	$0.79M	$24.92M cushion	Sales still cover break-even, but the buffer shrinks fast.
Fixed-cost pressure	Monthly fixed costs rise 25% to about $776k.	$0.99M	$29.26M cushion	Higher overhead lifts the threshold, so cash burn matters more.
Margin pressure	Scrap, power, and alloy input costs rise 20%.	$0.82M	$29.43M cushion	Margin weakens, but break-even stays well below planned sales.
Combined pressure	Sales fall 15%, fixed costs rise 25%, and variable costs rise 20%.	$1.02M	$24.69M cushion	When volume, overhead, and inputs move together, Month 9 cash risk jumps.

What should you verify before signing the steel plant lease?

Founder checklist

The plant only works if Year 1 volume, power, supply, staffing, and cash all line up before you commit to the build. The model shows Month 1 operating break-even, but the real gate is the $262.5M cash trough in Month 9 and the 24-month payback.

1Site Volume430,000 tons

Verify the site and sales plan can handle 430,000 Year 1 tons before you sign a lease, because that is the base load behind the model.

2Power Build$45M

Verify utility capacity and power delivery are real before EAF spend, since the model already sets aside $45M for power distribution infrastructure.

3Supply LockY1 inputs

Verify scrap steel, alloying agents, refractory materials, rail or truck access, and environmental controls before first production, or the first heats can slip.

4Crew Ramp1/10/8

Verify Year 1 staffing stays near 1 Plant Manager, 10 EAF Operators, and 8 Maintenance Technicians, because hiring ahead of ramp pushes costs up fast.

5Unit Economics78.3% CM

Verify the mix still clears about 78.3% contribution margin after direct costs, 5% plant overhead, logistics, and commissions, because that margin has to cover about $611.3k of monthly fixed burn.

6Cash Cushion$262.5M

Verify you can fund the Month 9 cash low of about $262.5M, and do not confuse Month 1 break-even with payback, which takes 24 months.
