Which expenses are fixed, and which move with sales in an animal behavior research service?

Cost classification

Break-even is only useful if overhead is separated from project-linked spend. In the first operating year, variable items total 28% of revenue before payroll and fixed overhead, so misclassifying one line can move the target fast.

Expense	Cost	Break-Even Treatment	Common Mistake
Specialized lab and office lease	Fixed	Include $12,500 per month in baseline overhead before calculating required project revenue.	Spreading rent across projects and hiding the true monthly break-even load.
Professional liability insurance	Fixed	Include $2,200 per month as recurring overhead from Month 1 through Month 60.	Treating insurance as optional until revenue ramps, even though coverage is needed before field work starts.
Cloud computing and storage	Variable	Model as 8% of revenue in the first year, falling to 6% by the mature year.	Using a flat software budget and missing usage spikes from data-heavy analysis work.
Bio-logger hardware consumables	Variable	Model as 10% of revenue in the first year, declining to 7.5% by the mature year.	Ignoring consumables and overstating contribution margin on field research projects.
Field deployment logistics	Variable	Model as 7% of revenue in the first year, tied directly to project volume and field activity.	Treating travel and deployment work as fixed when each signed project adds real spend.
Utilities and high-speed connectivity	Semi-variable	Start with the $1,800 monthly base, then watch usage as field data and computing volume rise.	Assuming connectivity stays flat while larger datasets and remote monitoring increase usage.
Senior Field Biologist staffing	Semi-fixed	Add capacity in staffing steps; the model starts with 2 FTE in the first year and grows with scale.	Hiring full teams before signed work and pushing break-even farther out.
Maintenance of field equipment	Semi-fixed	Include the $4,000 monthly base, then review step-ups as equipment fleets and project count expand.	Leaving Month 1 to Month 10 equipment purchases out of cash planning and confusing them with operating break-even.

How does break-even shift from lean advisory work to full field and model scale?

Scenario table

Break-even moves with project mix because field research, analysis, and custom models carry different margins and staffing needs. Lean work still has a wide gap, base gets close, and full scale finally creates a cushion.

Planning assumptions only; actual results can move with project mix, staffing, and utilization.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean advisory-light mix	$70.5K	$19.7K	$102K	72%	$-51.3K	Needs about $71K more revenue each month to break even.
Base mixed research-and-analysis mix	$159.3K	$40.6K	$128.1K	74.5%	$-9.4K	Almost there, with only a small monthly shortfall left.
Full fieldwork and model-development mix	$257K	$60.4K	$181.1K	76.5%	$15.5K	This mix clears break-even and adds a modest monthly cushion.

What pushes this animal behavior research service past break-even?

Stress test

Year 2 revenue runs about $159.3k a month against break-even near $171.9k, so the plan is still short. If billable hours stay under 42 per active customer, or travel and payroll run hot, the Month 21 break-even moves out.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$171,900	$12,600 gap	Billable hours need to stay above 42 per active customer.
Revenue shortfall	Monthly revenue falls 10% below Year 2 pace as fewer contracts close.	$171,900	$28,500 gap	Unsigned field access and low retainer coverage widen the gap fast.
Fixed-cost increase	Payroll rises from $740k in Year 1 to $965k in Year 2 before added overhead.	$224,100	$64,800 gap	Payroll creep can outrun revenue even before field costs rise.
Margin pressure	Fieldwork-heavy contracts push delivery and logistics costs back to 28% of revenue.	$184,000	$24,700 gap	Long travel windows and equipment downtime squeeze contribution.
Combined pressure	Revenue slips 10%, payroll rises, and travel windows stay long.	$240,000	$96,600 gap	Access delays, weak retainer coverage, and staffing creep can keep EBITDA negative.

What should this founder verify before signing the lease and hiring the first research team?

Founder checklist

Don’t lock in the lease, field team, or gear until the signed project pipeline, partner access, and cash runway line up with Month 21 break-even. The model only works if Year 1 margins hold and you can absorb the $561K cash trough by Month 29.

1Pipeline proofBefore hire-up

Confirm signed projects are in hand before you add full research staff, because Year 1 revenue is $846K and the plan only reaches break-even in Month 21.

2Site accessTravel cleared

Get partner approvals before booking field travel, because the work cannot start without access and delays here push billable hours off schedule.

3Lease load$88.7K/mo

Your fixed base is about $88.7K a month, and Year 1 variable plus COGS costs are 28% of revenue, so contribution margin is about 72%; keep the $12.5K site only if it supports billable work.

4Gear timing$420K phased

Stage the $420K core gear bundle after the pipeline is live, so drones, acoustic arrays, compute nodes, the mobile field station, and lab diagnostics don't drain cash too early.

5Utilization42 hrs

Check that 42 billable hours per active customer each month is real, or you’ll hire Senior Field Biologists, Data Scientists, and Project Managers ahead of demand.

6Cash trough-$561K

Fund the Month 29 cash low before scaling, because the model bottoms at negative $561K even after EBITDA turns positive in Year 3.
