Cost classification

Break-even is only reliable if $242,000 of monthly plant overhead stays fixed while materials, commissions, and logistics move with units sold. Misclassifying lease or launch payroll as unit costs can make Month 1 break-even look cleaner than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
Factory Lease	Fixed	Include $150,000 per month in fixed overhead from Month 1 through Month 60.	Spreading the lease across each turbine and hiding idle plant risk.
Insurance Premiums	Fixed	Include $25,000 per month regardless of whether production is 16 units or higher volume.	Reducing insurance when unit volume dips, which understates the break-even hurdle.
Blades & Hub	Variable	Apply per unit produced, from $100,000 for an Onshore 3MW Turbine to $450,000 for an Offshore 15MW Turbine.	Using one blended materials rate and missing product mix swings.
Sales Commissions	Variable	Apply as a percentage of revenue, starting at 3.0% in the first year and stepping down in later years.	Modeling commissions as fixed payroll instead of sales-linked expense.
Shipping & Logistics	Variable	Apply as a percentage of revenue, starting at 2.0% in the first year and falling to 1.5% by the mature year.	Treating freight as flat even though turbine size and sales volume drive spend.
Facility Utilities	Semi-variable	Use the product revenue rate in manufacturing overhead, such as 0.7% for the Onshore 3MW Turbine and 0.5% for the Offshore 10MW Turbine.	Combining production utilities with the fixed $12,000 administrative utilities line.
Indirect Factory Labor	Semi-variable	Apply the revenue-linked overhead rate by product, ranging from 1.1% to 2.0% in the model.	Counting all factory labor as direct unit labor and overstating contribution margin.
Manufacturing Technicians	Semi-fixed	Add capacity in staffing steps, from 5.0 FTE in the first year to 20.0 FTE in the stabilized period.	Treating technician payroll as perfectly variable with each turbine shipped.

How does break-even change from lean to full production in wind turbine manufacturing?

Scenario table

Break-even stays strong as output scales because selling prices stay far above direct unit cost. The real risk is cash timing, since fixed overhead and capex land before customer cash does.

Planning assumptions only; cash can still swing with deposits, supplier terms, warranty reserves, and capex timing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean Year 1 mix	$7.0M	$1.2M	$385K	82.6%	$5.4M	Clear cushion; prices sit far above direct cost.
Base Year 3 mix	$94.5M	$15.4M	$513K	83.6%	$78.6M	Still well above break-even, with stronger scale.
Full Year 5 mix	$354.9M	$57.0M	$552K	83.9%	$297.3M	Very strong margin, but cash timing still matters.

What breaks the break-even plan for wind turbine manufacturing?

Stress test

Year 1 has a wide cushion above break-even. The main downside risk is a 20% order drop, higher plant overhead, or margin compression from steel, composites, freight, rework, and warranty claims.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$466K	$6.58M cushion	Strong cushion, so launch timing matters more than survival.
Revenue shortfall	Monthly revenue falls 20% while margin holds.	$466K	$5.17M cushion	Delayed purchase orders can still cut profit fast.
Fixed-cost pressure	Monthly fixed overhead rises 15%.	$536K	$6.51M cushion	Factory and headcount overhead can outrun sales growth.
Margin pressure	Contribution margin drops from 82.6% to 77.6%.	$497K	$6.54M cushion	Steel, composites, freight, rework, or warranty claims can squeeze margin.
Combined pressure	Revenue falls 20%, fixed costs rise 15%, and margin slips to 77.6%.	$571K	$6.47M cushion	Backlog softness and input inflation hit the cushion at the same time.

What should you verify before signing the factory lease and buying heavy tooling?

Founder checklist

The model shows breakeven in Month 1, but only if signed orders, supplier quotes, and staffing line up. With $242K in monthly fixed costs, $1.72M in Year 1 payroll, and a $2.692M cash trough in Month 6, don’t commit on hope.

1Demand proof36 units

Verify signed orders or funded milestones can support the Year 1 mix of 10 onshore 3MW, 5 onshore 5MW, 1 offshore 10MW, 0 offshore 15MW, and 20 component kits before you lock the plant.

2Factory fit$242K/mo

Check crane access, floor load, yard space, heavy haul routes, and utility capacity before you sign the $150K monthly lease, because the full fixed base is $242K each month.

3Tooling plan$34M capex

Stage the $15M buildout, $8M machinery, $3M R&D lab equipment, and $2.5M testing gear against signed orders or funded milestones, because the plant ties up a lot of cash before steady output.

4Margin stack82.7% CM

Here’s the quick math: $84.5M of Year 1 revenue leaves about $69.8M after product COGS, sales commissions, and shipping, so lock supplier quotes before you spend on the line.

5Payroll ramp$1.72M

Year 1 staffing costs $1.72M and totals 12.5 FTE, so keep hiring tied to backlog and do not add technicians ahead of purchase orders.

6Cash cushionMonth 6

Match customer deposits, supplier terms, and logistics timing to the long build cycle, because the model bottoms at negative $2.692M in Month 6.
