Cost classification

Classification matters because break-even fails when overhead and usage-linked work get blended. In the first year, variable load is 29% of revenue, so misclassifying one major line can distort the Month 19 break-even point.

Expense	Cost	Break-Even Treatment	Common Mistake
Specialized Lab Rent	Fixed	Adds $15,000 to monthly overhead from Month 1 through Month 60, regardless of project volume.	Ignoring the lab access base load before revenue ramps.
Professional Liability Insurance	Fixed	Adds $4,500 to monthly overhead and should be covered before any contribution margin counts as profit.	Treating insurance as deal-linked when it runs every month.
Quality Management Systems	Fixed	Adds $3,000 to monthly overhead for compliance support across the operating period.	Leaving compliance overhead out of the break-even base.
Research Payroll	Semi-fixed	Steps up as staff capacity grows; first-year roles include 1 Chief Scientist, 2 Space Physiologists, and 2 Lab Technicians.	Modeling each hire as variable with revenue instead of capacity.
Lab Consumables and Reagents	Variable	Moves with project revenue at 12% in the first year, falling to 8% by the mature year.	Using a flat monthly estimate instead of tying usage to research work.
Cloud Computing and HPC Resources	Variable	Moves with analysis volume at 8% of revenue in the first year, falling to 6% by the mature year.	Treating compute usage like rent when project load drives it.
Travel and Conference Fees	Variable	Moves with commercial activity at 5% of first-year revenue, then declines to 3% by the mature year.	Locking travel into fixed overhead despite revenue-based modeling.
Subcontracted Clinical Evaluations	Variable	Moves with project revenue at 4% in the first year, falling to 2% by the mature year.	Treating subcontracted evaluations like fixed overhead.

How does break-even shift from lean to full capacity in this space medicine research service?

Scenario table

The lean case is still below fixed-cost coverage, the base case is almost flat, and full capacity turns the model positive. Contribution margin is the share left after variable costs, so higher contract volume, billable hours, and pricing improve coverage.

Planning case only: these figures use model assumptions, and actual results will vary with contract timing, billable hours, and pricing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$118.8K	$34.5K	$154.9K	71.0%	-$70.5K	Still short of fixed-cost coverage.
Base case	$290.0K	$76.9K	$214.5K	73.5%	-$1.3K	Almost flat, so small swings matter.
Full-capacity case	$500.5K	$120.1K	$278.5K	76.0%	$101.9K	Positive cushion, with overhead covered.

What breaks the break-even plan if contracts slip or costs rise?

Stress test

Month 19 is the knife edge. The model is almost at break-even now, but delayed contracts, heavier consumables, or hiring ahead of signed work can widen the cash gap fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$3,496,000	$16,000 gap	Month 19 is the knife edge.
Revenue shortfall	Revenue slips to Year 1 revenue while Year 2 overhead stays.	$3,496,000	$2,070,000 gap	Delayed contract starts leave a much larger coverage hole.
Fixed-cost increase	Year 3 staffing and marketing lift fixed overhead to about $238,500 a month.	$3,766,000	$2,240,000 cushion	Hire ahead of signed work and the break-even bar jumps.
Variable-expense pressure	Lab consumables and subcontracted clinical evaluations rise to Year 1's 29% load.	$2,911,000	$569,000 cushion	Higher wet-lab and subcontract spend cuts margin fast.
Combined pressure	Revenue slips to Year 1 levels, Year 3 overhead stays, and 29% variable load holds.	$4,641,000	$3,215,000 gap	Lower sales plus heavier staffing creates a sharp cash squeeze.

Should you sign the lab lease and hire the full scientific team yet?

Founder checklist

Not yet, unless you already have signed or near-signed work covering the first-year load. Break-even lands in Month 19, so the lease, hiring, and equipment plan should move only after the contract hours and pricing prove out.

1Demand lock-inSigned work

Confirm signed or near-signed projects before hiring the full scientific bench, because Year 1 assumes 160 contract research hours, 80 data analysis hours, and 20 consulting hours.

2Service pricing$450/$350/$600 hr

Test those hourly rates with real buyers first, since the model only works if contract research, data analysis, and consulting clear at those prices.

3Fixed load$36K/mo

Verify the lab can run at the $15,000 monthly rent plus the other fixed lines, because fixed spend is about $36,000 a month before one invoice clears.

4Staff ramp7.5→21 FTE

Hold staffing to the contract pace, since the model starts at 7.5 FTE in Year 1 and climbs to 21 FTE by Year 5.

5Capex phasing$1.615M

Phase the $450,000 mass spectrometer, $300,000 genetic sequencers, and $200,000 HPC build behind signed demand, because total capex is $1.615 million.

6Cash cushionMonth 19

Keep cash coverage through Month 19, when minimum cash bottoms at negative $1.736 million, or the business runs into a funding gap before break-even.
