Cost classification

Your break-even date only holds if materials, labor, commissions, shipping, and overhead are classified cleanly. With break-even in Month 2, don’t bury per-unit production inputs inside overhead.

Expense	Cost	Break-Even Treatment	Common Mistake
Manufacturing Facility Lease	Fixed	Include $15,000 per month in the overhead base that must be covered before profit.	Treating plant rent as unit-driven when it stays flat across the monthly planning range.
Administrative Office Rent	Fixed	Include $4,000 per month in fixed operating overhead for break-even revenue.	Leaving office rent below the line and understating the monthly sales target.
R&D Software Licenses	Fixed	Include $1,200 per month as recurring overhead from Month 1 through Month 60.	Misreading the license spend as $12,000 per month instead of $1,200.
Steel and Fabrication	Variable	Charge $400 per Industrial Weld Station sold before calculating contribution margin.	Hiding steel inputs in overhead and overstating margin on each table.
Direct Assembly Labor	Variable	Apply the unit rate by product, from $2 per filter kit to $150 per lab extraction unit.	Averaging labor across products and missing which units carry the margin.
Facility Utilities	Semi-variable	Model the 1.0% of revenue proxy as production-linked usage, then separate any base utility load when actual bills arrive.	Treating all utilities as fixed and missing the power draw from higher production volume.
Factory Insurance	Semi-fixed	Use the 0.5% of revenue proxy as a capacity-linked overhead step, not a true per-unit charge.	Letting insurance rise smoothly with every sale instead of stepping with insured assets and scale.
Sales Commissions	Variable	Deduct 5.0% of first-year revenue before contribution margin; the rate falls to 3.0% by the mature year.	Booking commissions as fixed payroll and overstating break-even contribution.

How does break-even shift from lean to full production for downdraft table manufacturing?

Scenario table

Lean sits near 61% contribution margin, and it improves as volume and filter-kit mix rise. That lowers break-even risk because fixed costs spread over more revenue, but table demand still has to carry the plan.

Planning assumptions only; actual break-even will move with mix, scrap, and ramp speed.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean Year 1 ramp	$1.41M	$553k	$62.9k	60.9%	$797k	Month 2 breakeven; launch cash risk is tight.
Base Year 3 mix	$3.08M	$1.08M	$91.2k	64.9%	$1.91M	Steady cushion; overhead absorption is much better.
Full Year 5 scale	$5.80M	$1.83M	$124.2k	68.4%	$3.85M	Wide cushion; filter kits help mix, but table demand still matters.

What breaks the break-even plan for downdraft table manufacturing?

Stress test

The plan has a solid first-year cushion, but it gets thinner fast if sales slip or steel, labor, and freight costs climb together. At about $1.41M in average monthly revenue versus roughly $103K in break-even revenue, the base cushion is about $1.31M a month.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change in sales mix, variable rates, or fixed overhead.	$103K/month	$1.31M cushion	Base plan clears break-even by a wide margin.
Revenue shortfall	Year 1 revenue runs 15% below plan.	$103K/month	$1.10M cushion	Sales can soften, but the plan still holds if volume stays close.
Fixed-cost pressure	Lease, admin, and salary overhead rise 20%.	$124K/month	$1.29M cushion	Overhead creep lifts the break-even floor quickly.
Margin pressure	Steel, components, and freight push variable cost load up 5 points of revenue.	$119K/month	$1.29M cushion	Input cost pressure cuts the 61% base contribution margin.
Combined pressure	Revenue falls 15%, fixed costs rise 20%, and margin slips to 53%.	$142K/month	$1.06M cushion	One weak quarter plus cost creep still leaves room, but the cushion shrinks fast.

Can you prove Year 1 demand and cash before you lock the lease and buy the line?

Founder checklist

You're ready to sign only if booked demand, list prices, supplier quotes, and cash all support a Month 2 breakeven. With $62.9K in monthly fixed load and $685K of capex, the deal has to clear the first-year ramp without over-hiring.

1Booked demand4.9K + 5K

Confirm qualified orders cover 4,900 tables and 5,000 filter kits in Year 1, because launch demand has to exist before the fixed cost base makes sense.

2Price floor$4.5K to $250

Hold the listed prices on all five product lines, or margin slips fast once freight, commissions, and overhead hit.

3Supplier quotes≈80% GM

Lock steel, fan, filter, control, and labor quotes near the listed unit costs so the gross margin stays close to plan.

4Fixed load$62.9K/mo

Check that lease, office, software, maintenance, utilities, and the first salaried team stay near this monthly burn before you sign.

5Capex stage$685K

Stage the fabrication, press brake, conveyor, robot, coating booth, lab, forklift, and ERP spend so the build does not outrun demand.

6Cash and hires$1.096M / 5 FTE

Keep opening cash above the Month 1 floor and do not add headcount beyond the first five salaried roles until throughput is proven.
