Which dry powder inhaler supply expenses are fixed and which move with sales?

Cost classification

Your break-even is reliable only if per-unit inputs, freight, and commissions move with sales while lease, certification, insurance, and base overhead stay monthly. Misclassify compliance or staffing, and Month 1 break-even can look safer than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
Medical Grade Polymer	Variable	Apply the $0.25 per-unit input to each unit produced before calculating contribution margin.	Putting material spend in overhead and overstating margin as volume rises.
Direct Assembly Labor	Variable	Model per-unit assembly labor in unit economics, from $0.30 to $2.50 depending on device type.	Blending per-unit labor with salaried technicians and hiding true unit margin.
Outbound Freight and Logistics	Variable	Charge freight as a revenue-linked expense: 2.5% in Year 1 and 1.8% in Year 5.	Using a flat monthly freight budget when shipment volume drives the spend.
B2B Sales Commissions	Variable	Deduct commissions from revenue at 3.0% in Year 1, declining to 1.5% in Year 5.	Treating commissions like fixed payroll and overstating break-even sales coverage.
Cleanroom Facility Lease	Fixed	Include $22,000 per month in fixed overhead for the full operating period.	Spreading lease expense per unit and making low-volume months look too profitable.
ISO Certification Maintenance	Fixed	Use the $3,500 monthly amount as fixed overhead from Month 1 through Month 60.	Treating all compliance as variable; regulatory compliance fees are separate at 0.5% of revenue.
Manufacturing Technicians	Semi-fixed	Model staffing in capacity steps, rising from 4 FTE in Year 1 to 12 FTE in Year 5 at $65,000 salary.	Assuming technician payroll moves smoothly with every extra unit produced.
IT and Data Management plus Cloud Infrastructure	Semi-variable	Keep the $4,000 monthly IT base separate from cloud infrastructure at 0.6% of revenue.	Calling the whole digital support stack fixed and missing connected-device usage load.

How does break-even change from lean to full production for this inhaler supply model?

Scenario table

Lean uses the break-even floor, base uses the first-year run rate, and full uses the fifth-year scale. Fixed costs rise from about $146.5K a month to $235.2K, so revenue must climb, but the cushion gets much stronger.

Planning case figures are modeled assumptions, not a guarantee of actual demand, pricing, or margin.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean pre-commitment case	$0.21M	$0.06M	$0.15M	70.5%	$0.00M	Only covers fixed cost; one miss turns it negative.
Base launch planning case	$1.62M	$0.48M	$0.15M	70.5%	$0.99M	Holds about $1.41M above break-even each month.
Full scaled distribution case	$12.91M	$3.00M	$0.24M	76.8%	$9.68M	Strong cushion, but volume has to stay on plan.

What can push this inhaler supply business off break-even?

Stress test

Year 1 revenue sits well above the $208K monthly break-even, with about $1.41M of cushion. The main risk is slower adoption plus higher freight, rework, or fixed overhead, because those three push the floor up fast and can shrink the buffer month by month.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$208K/mo	$1.41M cushion	Year 1 stays well above break-even.
Revenue shortfall	Monthly revenue comes in $100K below plan.	$208K/mo	$1.31M cushion	A slower launch still clears break-even, but the room shrinks.
Fixed-cost pressure	Monthly fixed costs rise by $100K.	$350K/mo	$1.27M cushion	Lease, compliance, or staffing creep pushes the floor up fast.
Margin pressure	Freight and rework add $100K of monthly variable cost.	$350K/mo	$1.27M cushion	Freight, commissions, or rework drift can erode the buffer.
Combined pressure	Revenue slips $100K, fixed costs rise $100K, and freight adds $100K.	$634K/mo	$884K cushion	That mix cuts the buffer by more than a third.

What should you verify before you lock the cleanroom lease and launch spend?

Founder checklist

Check the launch mix, supplier terms, and cash cushion before you lock the lease and order inventory. The model only works if you can carry $146.45K of monthly fixed load, keep at least $876K cash in Month 1, and fund the $2.375M capex separately.

1Supplier termsNet terms

Get supplier terms in writing before the first inventory order, so cash does not get tied up before sales start.

2Year 1 mix1.905M units

Confirm the opening-year volume plan is really 1.2M single-dose, 450K multi-dose, 150K pediatric, 80K high-payload, and 25K connected units, because break-even depends on that mix.

3Unit margin78.6%-85.3%

Verify that the price deck still clears unit cost, because the modeled gross margin runs from 78.6% on multi-dose to 85.3% on connected units before overhead.

4QC stack5 controls

Make sure testing, sterilization, regulatory compliance, environmental monitoring, and batch record review are in place before shipment, or revenue can get stuck behind hold-and-release delays.

5Staffing ramp10 FTE

Check that the opening team can cover engineering, QA, regulatory, sales, and manufacturing at 10.0 FTE in Year 1, because shortages here slow output and raise overtime risk.

6Fixed load$146.45K/mo

Keep at least $876K in Month 1, and do not sign the $22K lease until pipeline and regulatory readiness are clear; approve the $2.375M launch capex separately from break-even.
