Cost classification

Break-even is only useful if fixed costs stay in the monthly base and unit-linked costs move with volume. Here, leases and insurance set the hurdle, while packs, labor, commissions, logistics, and energy move with production or revenue.

Expense	Cost	Break-Even Treatment	Common Mistake
Factory Lease	Fixed	Use $200,000/month as baseline plant overhead.	Tying the lease to vehicle count.
Showroom & Service Center Leases	Fixed	Use $150,000/month in fixed selling and service overhead.	Burying it inside variable selling expense.
Insurance General & Product	Fixed	Use $40,000/month as recurring coverage overhead.	Treating it as per-vehicle warranty expense.
Battery Pack	Variable	Apply $1,500 to $4,000 per unit by model.	Averaging battery spend before sales mix is known.
Assembly Labor	Variable	Apply $250 to $500 per unit by model produced.	Putting all assembly labor into fixed payroll.
Sales Commissions	Variable	Apply 3.0% of revenue in the first year, declining to 2.0% in Year 5.	Modeling commissions as a flat monthly amount.
Delivery Logistics	Variable	Apply 2.0% of revenue in the first year, declining to 1.5% in Year 5.	Leaving vehicle delivery out of contribution margin.
Production Line Workers	Semi-fixed	Add staffing in steps from 10 FTE in Year 1 to 50 FTE in Year 5.	Scaling headcount smoothly with every extra vehicle.

How does break-even change as production moves from a lean pilot to full capacity?

Scenario table

Break-even gets easier as volume rises because the same factory and payroll base gets spread across more vehicles. The mix also holds a strong contribution margin, so the fixed-cost cushion widens from launch to mature run-rate.

Planning assumptions only; these figures are model-based, not a promise of future results.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean pilot run	$27.1M	$4.5M	$0.7M	83.4%	$21.9M	Launch month break-even is met, but the cushion is thin if ramp slips.
Base ramp-up	$138.6M	$22.2M	$0.9M	84.0%	$115.4M	Scale covers fixed costs well and makes the plant less sensitive to demand swings.
Full-capacity assembly	$265.8M	$41.3M	$1.1M	84.5%	$223.3M	Mature volume gives the widest cushion and the strongest fixed-cost absorption.

What breaks the break-even plan for an automobile manufacturer?

Stress test

This model clears break-even easily in the base case, but the cushion shrinks fast if launch volume slips, plant overhead runs hot, or supplier and warranty costs climb. The main risk is margin pressure, not demand alone.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$846K	$26.3M cushion	Strong base-case cushion.
Revenue shortfall	Monthly revenue is $1M lower.	$846K	$25.3M cushion	A sales miss trims cushion, but not enough to break the model.
Fixed-cost increase	Monthly plant overhead rises by $100K.	$966K	$26.2M cushion	Overhead moves break-even up, so factory and staff spend matter.
Margin pressure	Revenue-based variable costs rise 1 point.	$857K	$26.3M cushion	Supplier, scrap, and warranty pressure can erode margin fast.
Combined pressure	Monthly revenue falls $1M, overhead rises $100K, and variable costs rise 1 point.	$977K	$25.1M cushion	A weak launch plus higher costs narrows the cushion quickly.

Can you prove the plant still clears break-even before you sign the factory commitment?

Founder checklist

Don’t sign the plant commitment until the model covers the full opening burn and the Month 5 cash dip. If the capex, lease, supplier, and staffing plan can’t survive that ramp, break-even is still a paper story.

1Capex gate$116M

Verify the $50M building and land, $30M machinery, $15M R&D lab, $10M tooling, $5M showroom, $3M service center, $2M IT, and $1M test fleet are funded before you rely on sales cash.

2Fixed load$705.8K/mo

Verify the $200K factory lease is not signed unless the full $705.8K monthly fixed load is already covered.

3Demand proof5,300 units

Verify Year 1 demand can absorb 2,000 sedans, 1,500 SUVs, 1,000 compact EVs, 500 luxury sedans, and 300 performance SUVs, or the launch plan is too wide.

4Margin check83.4% CM

Lock battery pack, motor, chassis, interior, assembly, sales commission, delivery, and warranty terms so contribution margin, the cash left after variable costs, stays near 83.4%.

5Staffing ramp10 FTE

Verify the line starts with 10 full-time equivalent production workers in Year 1, not the 50-worker mature plan, so headcount tracks volume.

6Cash cushionMonth 5, -$5.744M

Verify you can fund the Month 5 trough before hiring ahead of demand, because minimum cash bottoms at -$5.744M.
