Cost classification

Break-even is only reliable if stable overhead, unit costs, revenue-linked fees, and step-up labor sit in the right buckets. Here, fixed admin overhead is $32,000/month before wages, while production costs move with units or revenue.

Expense	Cost	Break-Even Treatment	Common Mistake
Facility rent, admin utilities, insurance, software, office supplies, legal, accounting, and marketing	Fixed	Load $32,000/month from Month 1 before payroll.	Spreading these across units and hiding true monthly burn.
CEO, CTO, Head of Manufacturing, R&D, sales, quality, and HR salaries	Fixed	Model non-technician payroll as a fixed monthly commitment of $90,833 in the first year.	Treating leadership and admin payroll as if it falls when unit volume dips.
Raw materials, direct labor, wafer fabrication, assembly & test, and packaging	Variable	Apply per-unit manufacturing expense by component, from $8 to $25 per unit.	Using one blended unit amount too early and missing product mix risk.
Sales commissions	Variable	Apply 3.0% of revenue in the first year, declining to 2.0% by the fifth year.	Entering commissions as a fixed sales department line.
Shipping & Logistics	Variable	Apply 2.0% of revenue in the first year, declining to 1.5% by the fifth year.	Ignoring freight drag when sales volume scales.
Factory overhead, indirect production labor, production utilities, maintenance, and QA overhead	Semi-variable	Apply the revenue-linked portion at 3.0% of revenue based on the model inputs.	Treating all factory overhead as fixed when the model ties part of it to revenue.
Manufacturing Technician staffing	Semi-fixed	Start at 5 FTEs, or $25,000/month in the first year, then step up to 18 FTEs by the fifth year.	Assuming technician payroll rises smoothly with every extra unit.

How does break-even change from lean pilot orders to full production?

Scenario table

Break-even moves fast because unit mix, selling price, and fixed headcount absorb cost differently. At lean output you’re at the floor; by Year 5, the same plant cost is spread across far more units, so the cushion widens.

Planning-only figures. Yield and scrap rate are not fixed here, so treat them as user inputs and test them before you fund capacity.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean pilot floor	$180.3k	$32.5k	$147.8k	82.0%	$0	This is the floor; any weaker mix or yield miss pushes loss risk up.
Year 1 funded launch	$5.51M	$948.8k	$147.8k	82.8%	$4.41M	Above break-even with a wide cushion, but yield and scrap still matter.
Year 5 scaled utilization	$26.44M	$4.26M	$252.0k	83.9%	$21.93M	Scale gives a much wider cushion, so cost drift becomes the main risk.

What breaks the break-even plan if demand softens or factory costs rise?

Stress test

At a first-year run-rate near $5.51M a month, break-even is about $180K, so the base plan has a wide cushion. The real risk is a slow ramp plus scrap, overtime, utilities, or compliance costs pushing the floor up before volume settles.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	First-year monthly revenue holds at the forecast run-rate.	$180K	$5.33M cushion	Break-even sits far below the base run-rate.
Revenue shortfall	First-year monthly revenue falls 25%.	$180K	$3.95M cushion	Demand is the first swing factor, but the model still clears break-even.
Fixed-cost pressure	Fixed costs rise 25% from higher rent, admin, and overhead.	$225K	$5.28M cushion	Higher overhead lifts the floor, so watch fixed spend.
Margin pressure	Variable expense load rises from 18% to 28% on more scrap and overtime.	$205K	$5.30M cushion	Margin pressure raises break-even even if sales hold.
Combined pressure	Revenue falls 25%, fixed costs rise 25%, and variable load rises to 28%.	$257K	$3.87M cushion	Slow demand plus cost creep is the clearest cash risk.

What should you verify before committing to an electronic component manufacturing plant?

Founder checklist

Don’t lock the lease, equipment, and headcount until signed or highly qualified orders can clear the $180,284 monthly break-even target. Keep Month 1 cash at or above $224K while the build and ramp are still in motion.

1Order proof$180.3K/mo

Verify signed or highly qualified orders can cover monthly break-even before you commit to the plant build.

2Mix spread$80-$250

Check that your product mix still works if sales lean toward lower-price memory chips, not just higher-price RF transceivers.

3Fixed load$32K/mo

Hold fixed admin spend near the model level before payroll and depreciation push break-even farther out.

4Input flow4 inputs

Confirm supplier lead times for raw materials, wafers, packaging, and test inputs before you commit to volume.

5QC rampMonth 5-8

Prove quality control, metrology, and assembly-test flow before hiring beyond the first 5 manufacturing technicians.

6Cash floor$224K

Keep launch cash above the Month 1 minimum while about $15.7M of capex is being deployed.
