Cost classification

Break-even is reliable only when monthly overhead stays separate from per-case spend. Here, launch assets are a cash need, not monthly overhead, so don’t bury capital purchases inside the operating break-even math.

Expense	Cost	Break-Even Treatment	Common Mistake
Cleanroom facility lease	Fixed	Use $18,500 per month in baseline overhead from Month 1 through Month 60.	Spreading cleanroom construction spend into monthly break-even overhead.
Cloud computing and HIPAA portal	Fixed	Use $4,500 per month as recurring platform overhead, separate from unit volume.	Treating the portal like a per-implant charge.
Insurance professional liability	Fixed	Use $6,800 per month while the business is operating within the modeled planning range.	Dropping insurance until revenue starts, which understates Month 1 cash need.
Salaried clinical, design, regulatory, sales, and software roles	Semi-fixed	Use about $112,500 per month in the first year, then step it up as full-time equivalent staffing rises.	Modeling salaries as a percent of revenue instead of hiring steps.
Titanium alloy powder	Variable	Apply per produced unit where titanium-based implants are made; for example, $320 for a cranial plate and $290 for an acetabular cup.	Averaging titanium spend across all products, including non-titanium surgical guides.
Sales commissions	Variable	Apply as a revenue-linked selling charge: 5.0% in the first year and second year, then lower rates in later years.	Counting commissions as fixed payroll and overstating contribution margin.
Factory quality control allocation	Semi-variable	Apply 1.2% of revenue as production oversight that scales with activity and compliance load.	Treating quality control as optional overhead instead of volume-linked production support.
Sterilization validation	Semi-variable	Apply 1.0% of revenue to reflect validation work tied to shipped medical device volume.	Putting sterilization equipment purchases into monthly break-even instead of separate cash planning.

How does break-even change as this implant business moves from a lean launch to full-scale production?

Scenario table

Revenue climbs faster than fixed overhead as the model moves from Year 1 to Year 5, so the break-even cushion gets wider. The catch is that demand, onboarding, and cleanroom capacity have to keep pace, or margin can stall.

Planning case figures are model assumptions, not promises.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$1.07M	$215k	$162k	80.0%	$697k	Smallest cushion, but still above break-even in Month 1.
Base case	$2.23M	$434k	$288k	80.6%	$1.51M	Healthy cushion; break-even risk stays low if volume holds.
Full-scale case	$4.21M	$765k	$456k	81.8%	$2.99M	Strong cushion, but cleanroom and design capacity become the limit.

What breaks the break-even plan if patient cases slow or costs rise?

Stress test

Here’s the quick math: Year 1 monthly revenue is about $1.074M vs. about $204k break-even, so the plan has about $870k of cushion at a 79.3% contribution margin. The squeeze points are slower onboarding, a weaker implant mix, and more rework or validation.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$204k	$870k cushion	The plan clears break-even with room to spare.
Revenue shortfall	Monthly revenue falls 30% from delayed hospital onboarding and a weaker mix of high-price implants.	$204k	$548k cushion	Cushion shrinks fast when case flow slips.
Fixed-cost pressure	Fixed overhead rises 10% as compliance staffing and admin spending climb.	$224k	$850k cushion	Payroll and compliance lift the floor before revenue moves.
Margin pressure	Variable costs rise 5 points from materials, rework, sterilization validation, shipping, commissions, and clinical travel.	$218k	$856k cushion	Quality and logistics costs hit coverage without much warning.
Combined pressure	Revenue falls 30%, fixed overhead rises 10%, and variable costs rise 5 points.	$240k	$512k cushion	This is the tightest case; delay hiring until volume proves out.

Have you verified surgeon demand and hospital onboarding before you commit to the cleanroom build?

Founder checklist

Only if Year 1 demand, pricing, and onboarding match the model. The plan depends on 3,000 units in the first year, about 250 a month, and a blended price near $4,297; if those slip, fixed costs and capex hit cash fast.

1Demand proof3,000 units

Verify surgeons can really support 3,000 units in Year 1, or about 250 a month, before you lock the buildout.

2Contribution margin79.3% CM

Check that the case mix still supports the $4,297 blended Year 1 price and leaves about 79.3% contribution margin after unit COGS, commissions, and clinical travel.

3Fixed load$161.5K/mo

Confirm the monthly fixed stack, including the lease, audit, cloud, insurance, marketing, admin, and Year 1 salaries, stays fundable at $161.5K before variable spend.

4Staffing ramp11 FTE

Hire to the 11 FTE Year 1 plan only when design, regulatory, sales, and software coverage is enough to avoid case delays.

5Production path$1.43M capex

Qualify the in-house or outsourced path before capex, because the printer, cleanroom, CNC station, scanners, and sterilization gear all need validation and quality inspection.

6Launch cash$981K / Month 1

Keep at least $981K in cash and do not commit more fixed spend unless hospital onboarding can start in Month 1.
