Which microgravity research expenses are fixed, and which move with mission sales?

Cost classification

Break-even in Month 16 depends on separating monthly overhead from mission-linked spend. If launch fees or payload rework sit in overhead, contribution margin looks safer than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
Clean Room Facility Lease	Fixed	Put the $15,000 monthly lease into fixed overhead.	Spreading lease across missions and hiding baseline burn.
Compliance & Regulatory Filings	Fixed	Put the $3,000 monthly filing spend into fixed overhead.	Treating required filings as optional project spend.
Scientific Payroll	Semi-fixed	Step payroll up when mission capacity and staffing plans expand.	Modeling engineers as fully variable labor per payload.
Launch Service Access Fees	Variable	Reduce contribution margin by the revenue-linked launch fee rate.	Treating launch-linked spend like overhead.
Payload Hardware Components	Variable	Reduce contribution margin by the payload hardware percentage.	Ignoring rework tied to sample handling.
Data Processing & Cloud Storage	Variable	Reduce contribution margin as billable mission data scales.	Assuming cloud use stays flat as experiments grow.
Subcontracted Mission Support	Semi-variable	Model a base support load plus added effort for payload volume.	Using one flat rate for simple and complex missions.

How does break-even change across lean, base, and full operating scenarios for microgravity research services?

Scenario table

Break-even improves as the mix shifts from a lean Pharma Research Payload launch to a fuller book across all three service packages. Revenue grows faster than fixed overhead, so the Year 1 loss turns into a Year 3 cushion.

Planning case figures use model assumptions for package mix, hours, and rates; they are not guarantees.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean pharma-led Year 1 proxy	$114K	$33K	$141K	71%	-$60K	Below break-even; fixed load still outruns contribution.
Base mixed Year 2 proxy	$287K	$75K	$180K	74%	$33K	Near break-even now, with a small EBITDA cushion.
Full three-package Year 3 proxy	$496K	$119K	$235K	76%	$142K	Comfortably above break-even; margin can absorb more growth.

What breaks the break-even plan for microgravity research services?

Stress test

If flight slots slip or revenue falls, the plan loses its cushion fast. A 20% revenue miss, a margin drop to 66%, or 10% higher fixed costs pushes break-even up, and the combined hit leaves a wide gap before Month 16.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$1,809K	$0 gap	Base case breaks even in Month 16.
Revenue shortfall	Revenue lands at $1,447K, or 20% below target.	$1,809K	$362K gap	At 71% margin, the miss leaves a $257K operating gap.
Fixed-cost increase	Overhead rises 10%.	$1,990K	$181K gap	Support hiring ahead of contracts pushes the hurdle higher.
Margin pressure	Experiment spend cuts margin to 66%.	$1,946K	$137K gap	Rework, sample loss, or extra data handling raises the hurdle.
Combined pressure	Revenue lands at $1,447K, margin slips to 66%, and overhead rises 10%.	$2,141K	$694K gap	That mix creates a $458K operating gap and strains cash fast.

What should you verify before signing the clean room lease and ramping microgravity research spend?

Founder checklist

Before you commit to the clean room lease, make sure signed work, pricing, and cash can carry the fixed base through Month 16. If booked contracts do not cover the $38.0K monthly fixed load and the 29% variable stack, break-even slips fast.

1Signed work$1.37M

Confirm signed research contracts are in hand before you take the $15K monthly clean room lease, because the plan assumes $1.368M of Year 1 revenue and the lease starts immediately.

2Fixed base$38.0K/mo

Verify the non-payroll fixed base stays at $38.0K per month, since that burn exists even if mission timing slips.

3Variable load29%

Track launch access, hosting, payload hardware, and cloud costs so they stay near 29% of revenue; that leaves enough contribution to pay the rest.

4Staffing ramp$77.9K/mo

Don’t lock the full staffing ramp until mission cadence can absorb about $77.9K in monthly payroll from the five named roles.

5Cash runwayMonth 16

Keep cash funded through Month 16, where minimum cash bottoms at negative $629K; if reserves run short, the model misses break-even.

6CAC payback$12.5K

Hold marketing scale to a $12.5K CAC and only spend faster when booked contract revenue can pay it back through billable hours, especially with a $150K Year 1 budget.
