Cost classification

Break-even works only if payroll, rent, and tools stay in overhead while project-linked costs move with revenue. In the first operating year, variable delivery costs total 28% of revenue before fixed overhead.

Expense	Cost	Break-Even Treatment	Common Mistake
Principal Anthropologist payroll	Fixed	Include $175,000 per year, or about $14,583 per month, in monthly overhead.	Treating required founder or principal salary as optional.
Senior Cultural Strategist payroll	Fixed	Include $135,000 per year for each full-time equivalent in fixed monthly overhead.	Burying employee delivery staff inside gross margin.
Lead Ethnographer payroll	Fixed	Include $95,000 per year per full-time equivalent in the fixed break-even base.	Classifying employee time as project-only labor.
Operations and Project Manager payroll	Fixed	Include the first-year 0.5 full-time equivalent at $42,500 per year, or about $3,542 per month.	Ignoring the half-time role because it is not a full hire.
Freelance Researcher Fees	Variable	Model at 12% of first-year revenue because it scales with paid client work.	Double-counting it with employee payroll.
Participant Incentives	Variable	Model at 5% of first-year revenue as a direct study delivery expense.	Parking incentives in marketing instead of delivery expense.
Fieldwork Travel and Lodging	Variable	Model at 8% of first-year revenue because travel rises with field-heavy engagements.	Treating travel like fixed studio rent.
Annual Marketing Budget	Semi-fixed	Use the planned $45,000 first-year budget as a managed spend level, not a per-project charge.	Confusing total marketing budget with customer acquisition cost.

How does break-even change from a lean launch to a full practice?

Scenario table

Break-even gets easier as the mix shifts toward higher-value advisory and workshops, but fixed staffing also rises. So the real test is whether utilization keeps pace with payroll.

Planning assumptions only; later-year allocation percentages need normalization before client-count math.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch practice	$91.3k	$25.6k	$50.0k	72%	$15.7k	Month 7 break-even leaves a small cushion.
Base scale practice	$188.2k	$48.9k	$67.8k	74%	$71.5k	Higher retained advisory mix improves cushion.
Full expanded practice	$564.0k	$118.4k	$121.1k	79%	$324.5k	The widest cushion shows up in the mature team.

What breaks the break-even plan for this consulting firm?

Stress test

At $913k in monthly revenue, a 72% contribution margin, and $538k in fixed costs, the base plan clears break-even by about $166k a month. But a 20% revenue drop or 10% overhead rise can erase most of that cushion.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change from the Year 1 base case.	$747k/month	$166k cushion	This gives room, but not much room for delays.
Revenue shortfall	Average monthly revenue falls 20% to $730k.	$747k/month	$17k gap	Slow enterprise closes can flip the plan negative.
Fixed-cost increase	Fixed overhead rises 10% to $592k a month.	$822k/month	$91k cushion	More rent, software, or legal cost trims the buffer.
Margin pressure	Variable expenses rise from 28% to 33%.	$803k/month	$110k cushion	Fieldwork overruns and subcontractors eat margin.
Combined pressure	Revenue falls 20%, variable expenses rise to 33%, and fixed costs rise 10%.	$884k/month	$154k gap	This case creates about a $103k monthly operating gap.

What should the founder verify before locking the studio, hires, and fieldwork spend?

Founder checklist

Don’t lock the studio lease or add fixed hires until you can see enough signed or near-signed work to cover the model’s Month 7 break-even and Month 6 cash dip. In this business, demand proof and delivery capacity have to show up before overhead does.

1Pipeline Coverage$747K/mo

Verify signed or near-signed work is high enough to support the fixed base before you add more overhead, or break-even slips fast.

2Fixed Stack$12.75K/mo

Keep the non-payroll fixed load near this level until revenue is steady, because rent, software, legal, insurance, and utilities hit every month.

3Margin Check72% CM

Confirm pricing and service mix still leave about 72% contribution after freelance researchers, incentives, travel, lodging, transcription, and translation.

4Team Load7 active clients

Do not add the next full-time researcher until proposal volume can support about 7 active customers at 45 billable hours each per month.

5Cash Cushion$724K M6

Keep runway through the Month 6 low point, because the model needs this cash cushion before the plan can breathe.

6Launch Demand10 customers

Validate the Year 1 marketing math first: a $45K budget at $4.5K CAC only supports about 10 customers, so lock methods, consent, data storage, and compliance before fieldwork.
