Which expenses are fixed, variable, semi-variable, and semi-fixed for this medical equipment manufacturing break-even model?

Cost classification

Break-even is only reliable if each expense follows the right driver. Treat per-unit inputs and sales fees as variable, monthly departments as fixed, and capacity support as semi-fixed or semi-variable.

Expense	Cost	Break-Even Treatment	Common Mistake
Direct device materials and assembly inputs	Variable	Include in unit economics because parts, sensors, housings, labor, and software integration rise with units produced.	Using one blended bill of materials across products with very different unit inputs.
Sales Commissions	Variable	Apply as a revenue-linked selling expense, starting at 8.0% in the first year and declining to 6.0% by the fifth year.	Modeling commissions as payroll instead of a direct drag on contribution margin.
Marketing & Distribution Fees	Variable	Apply as a revenue-linked expense, starting at 5.0% in the first year and declining to 3.0% by the fifth year.	Leaving freight-out, channel fees, and distribution out of break-even contribution.
R&D Salaries Engineers	Fixed	Use $25,000 per month as fixed overhead across Month 1 through Month 60.	Spreading core engineering payroll across units and making margins look too stable.
Regulatory Affairs & QA Dept	Fixed	Use $15,000 per month as fixed overhead for compliance and quality leadership.	Treating QA staffing as a purely per-unit input; it supports the whole quality system.
Utilities & Internet	Semi-variable	Start with the $1,500 monthly base charge, then add usage when plant load and testing activity rise.	Keeping utilities flat even as production, cleanroom use, and test cycles increase.
Calibration Services	Semi-fixed	Model as a capacity support layer that steps up when more equipment, lines, or validation cycles are added.	Assuming calibration is purely per-unit; validation and calibration often move in batches.
Cleanroom Maintenance	Semi-fixed	Hold stable within a capacity band, then step up when operating scale or cleanroom support needs expand.	Linking cleanroom support only to sales volume instead of capacity and uptime needs.

How does break-even change from a lean build to a full production mix?

Scenario table

Fixed payroll and facility costs stay fairly steady, so break-even mostly moves with product mix. As higher-ticket systems enter the line, contribution rises faster than fixed cost and the cushion gets wider.

Planning case only; these are model assumptions for decision support, not a guarantee of actual results.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean break-even case	$172k	$50k	$122k	71.0%	$0	At this volume, the line just covers overhead.
Year 1 base case	$1.11m	$323k	$122k	71.0%	$668k	The model clears break-even fast and adds a solid monthly cushion.
Year 5 full mix case	$12.25m	$2.79m	$157k	77.3%	$9.31m	High-ticket systems create a wide cushion, but throughput still has to stay tight.

What breaks first if sales slip or costs rise?

Stress test

The base plan clears break-even, but the cushion shrinks fast if revenue drops or if compliance, rework, freight, or warranty reserves climb. The combined hit is the one to watch.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$172k	$941k cushion	Strong cushion, but sales timing still matters.
Revenue shortfall	Revenue is 20% below plan.	$172k	$718k cushion	Lower sales cut the cushion fast.
Fixed-cost increase	Fixed overhead is 25% higher.	$214k	$898k cushion	Added compliance overhead still leaves room.
Margin pressure	Variable expense load rises by 10 percentage points.	$200k	$913k cushion	Component price spikes, scrap, and rework hit margin.
Combined pressure	Revenue is 20% below plan, fixed overhead is 25% higher, and variable expense load rises 10 points.	$250k	$640k cushion	Order delays plus higher compliance and freight costs narrow the buffer.

What should you verify before you lock in plant space and equipment for a medical equipment line?

Founder checklist

Break-even looks strong on paper, but the real test is whether demand, supplier lead times, QA staffing, and cash hold before you sign the plant commitment. The model needs $1.041M of minimum cash in Month 1, and that is separate from $2.2M of capital spending (capex).

1Demand proof$13.35M Yr 1

Confirm you can actually sell the 1,500 pumps and 3,000 monitors in Year 1 before you lock plant space, because those two lines carry the opening revenue base.

2Fixed load$121.8K/mo

Verify you can fund about $121.8K a month of fixed operating burn from salaries and overhead, because that cost base starts before volume ramps.

3Contribution≈73% CM

Check that the Year 1 pump and monitor mix still clears about 73% contribution after the 13% sales and marketing load, so the fixed burn can be absorbed.

4Throughput ramp4,500 units

Phase hiring to the 4,500-unit Year 1 output mix, then add staff before Year 2 ultrasound and Year 3 robot work start, so labor stays tied to throughput.

5Cash cushion$1.041M

Keep at least $1.041M of cash ready in Month 1, and do not use the Month 1 break-even flag as a substitute for runway because the build also carries $2.2M of capex.

6Supplier readiness5 product lines

Validate lead times, minimum order quantities, and calibration plans for pumps, monitors, ultrasound, robot arms, and imaging systems before inventory buy-in, so launch does not slip on parts or test delays.
