Cost classification

Break-even only works if unit-driven spend sits in contribution margin and plant commitments sit in fixed costs. Misclassifying rent, launch payroll, or per-vehicle materials can make Month 1 break-even look safer than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
Manufacturing Plant Rent	Fixed	Include $150,000 per month in fixed overhead from Month 1 through Month 60.	Treating plant rent like it drops when unit volume misses plan.
R&D Software Licenses	Fixed	Include $25,000 per month in fixed overhead across the planning period.	Moving licenses into unit margin even though the monthly bill is committed.
Battery Cells	Variable	Include the per-vehicle amount in contribution margin by model, from $1,500 for a Compact Sedan to $3,000 for a Luxury Sedan.	Using one blended battery amount before checking model mix.
Sales Commissions	Variable	Include as a revenue-linked expense in contribution margin, starting at 2.0% in the first year and falling to 1.5% by the fifth year.	Putting commissions in fixed overhead and overstating margin at higher sales.
Factory Utilities	Semi-variable	Model as production-linked overhead, ranging from 0.5% to 0.7% of revenue depending on vehicle model.	Treating all utilities as fixed even when production hours drive usage.
Tooling Consumables	Semi-variable	Include as production-linked overhead, ranging from 0.5% to 0.7% of revenue by model.	Ignoring wear and consumables until volume ramps.
Assembly Line Workers	Semi-fixed	Include payroll as fixed within each staffing band, stepping from 5.0 FTE in the first year to 50.0 FTE in the fifth year.	Assuming launch payroll flexes down one-for-one with missed production.
Service Technicians	Semi-fixed	Include payroll as fixed within each service capacity step, rising from 1.0 FTE in the first year to 10.0 FTE in the fifth year.	Delaying service staffing in the model while still booking vehicle sales.

How does break-even change from a lean pilot ramp to a base scale-up and a full factory run?

Scenario table

All three cases clear the first-year monthly revenue hurdle, so the main risk is cash, not demand. As volume rises, fixed costs spread faster, and the full case gives the widest cushion.

Planning assumptions only; launch timing, mix, and supplier costs can move these figures.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean pilot line	$843.8K	$146.1K	$41.2K	82.7%	$654.8K	Clears break-even, but launch cash is still tight.
Base ramp	$3.16M	$543.8K	$48.6K	82.8%	$2.56M	The normal ramp clears break-even with more cushion.
Full factory run	$150.8M	$25.4M	$73.1K	83.2%	$124.5M	Strong cushion once the plant is fully loaded.

What breaks first if electric vehicle sales slip or costs run hot?

Stress test

The first-year plan clears break-even by a wide margin, but the cushion shrinks fast if throughput slips, battery input costs rise, or plant overhead climbs. Month 9 is the cash low point, so collections and working capital need tight control.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$5.96M	$95.29M cushion	Accounting break-even is covered, but cash still bottoms at -$46.0M in Month 9.
Revenue shortfall	Revenue runs 20% below plan.	$5.96M	$75.04M cushion	Lower throughput cuts the cash buffer hard, even if break-even is still covered.
Fixed-cost increase	Annual fixed costs rise 15% to $5.68M.	$6.86M	$94.39M cushion	Plant rent, service centers, and headcount push break-even up fast.
Margin pressure	Variable expenses rise 10% to $19.06M.	$6.09M	$95.16M cushion	Battery input inflation, scrap, and rework can erode margin before EBITDA turns red.
Combined pressure	Revenue falls 20%, variable expenses rise 10%, and fixed costs rise 15%.	$7.00M	$74.00M cushion	Delayed customer collections and lower volume can turn a paper profit into a cash squeeze.

Can an electric vehicle factory survive the ramp before you sign the plant, equipment, and supplier commitments?

Founder checklist

Before you lock in leases, equipment, and hiring, test whether the first-year ramp can carry the plant through Month 9. The model needs 1,850 vehicles, a ~$54.7K blended selling price, and enough margin to cover about $411.7K a month in fixed load.

1Year 1 volume1,850 units

Verify the five-model build plan is real, because that first-year volume has to show up before the factory can absorb its fixed base.

2Launch demand$54.7K ASP

Check that the model mix holds around $101.3M of first-year revenue, or the launch price will not support the ramp.

3Contribution margin86.7% CM

Confirm battery cells, powertrain components, body and chassis materials, assembly labor, software integration, sales commissions, and logistics stay at plan levels, because this margin funds the fixed bill.

4Fixed load$411.7K/mo

Use the $300K monthly fixed expense base plus about $111.7K of Year 1 wages to test whether operating cash can hold before scale.

5Staffing ramp11 FTE

Gate hiring against production trials, quality systems, supplier contracts, logistics capacity, and service coverage so labor does not outrun output.

6Cash trough-$46.0M

Make sure funding can absorb the Month 9 drawdown while $94M of capex is staged across plant construction, robotics, battery equipment, tooling, lab setup, software, service equipment, and admin facilities.
