Which expenses stay fixed, and which move with client volume?

Cost classification

Break-even works only if each expense follows the right behavior. Put revenue-linked tools and subcontractors below gross margin, but keep rent, core payroll, and admin overhead in the monthly hurdle.

Expense	Cost	Break-Even Treatment	Common Mistake
Office rent	Fixed	Carry $3,500 per month from Month 1 through Month 60.	Spreading rent across projects and hiding the true monthly hurdle.
Core delivery payroll	Fixed	Include active full-time equivalent salaries: founder at $180,000, senior consultant at $150,000, and data scientist at $120,000 annually.	Treating salaried delivery staff as variable just because they bill hours.
Legal, accounting, insurance, communication, and office overhead	Fixed	Include the recurring monthly base: $1,000 legal and accounting, $300 insurance, $250 communication, plus $500 supplies and utilities.	Leaving small recurring items out because each one looks immaterial.
Cloud computing and AI platform licenses	Variable	Model at 8% of revenue in the first year, declining to 6% by the mature year.	Treating usage-based tools as fixed and overstating margin as client volume rises.
Third-party data access fees	Variable	Model at 4% of revenue in the first year, declining to 3% by the mature year.	Forgetting data fees when custom work needs paid datasets or external access.
Digital advertising and lead generation	Variable	Model at 10% of revenue in the first year, falling to 6% by the mature year as acquisition efficiency improves.	Using only the annual marketing budget and ignoring revenue-linked acquisition spend.
Project-specific subcontractor fees	Variable	Model at 5% of revenue in the first year, declining to 3% by the mature year.	Calling subcontractors fixed when they rise with complex client delivery.
Software seats, admin tools, and training	Semi-fixed	Treat as a step-up expense tied to headcount, including $400 sales tools and $750 training per month at the base level.	Holding seat-based tools flat after adding consultants and support staff.

How does break-even shift from a lean AI consulting setup to a full team?

Scenario table

As support work and custom model projects grow, revenue per client-equivalent rises, but payroll rises too. That pushes break-even from about $49.4k a month in the lean case to about $71.5k in the base case and $114.6k in the full build.

Planning case numbers use the model assumptions above; actual break-even will move with staffing mix, close rates, and delivery load.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean AI Strategy	$51.7k	$14.0k	$36.1k	73%	$1.7k	Barely above break-even; a small drop can wipe out profit.
Base AI Strategy + Data Readiness	$142.9k	$35.4k	$53.8k	75.2%	$53.7k	Healthy cushion, but payroll is now doing more of the work.
Full AI Consulting Team	$296.3k	$66.7k	$88.8k	77.5%	$140.8k	Big cushion, but it depends on high utilization and recurring work.

What breaks the Year 1 break-even plan for an AI consulting firm?

Stress test

Year 1 is balanced only if signed work lands on time and delivery stays lean. A 10% revenue miss creates about a $3,600 monthly hole, and a 10% fixed-cost bump or 5-point margin drop pushes break-even above $53k.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$49,417	$0 cushion	The model is at break-even.
Revenue shortfall	Monthly revenue falls 10% to $44,475.	$49,417	$3,600 gap	Fewer signed projects can erase the whole month's profit.
Fixed-cost increase	Fixed costs rise 10% to $39,683.	$54,359	$4,942 gap	Extra hires or tools need more revenue fast.
Margin pressure	Variable expenses rise 5 points; contribution margin falls to 68%.	$53,051	$3,634 gap	Higher subcontractor or API spend eats the cushion.
Combined pressure	Revenue falls 10%, fixed costs rise 10%, and margin falls to 68%.	$58,357	$9,500 gap	This mix puts the month well below break-even.

Have you proved enough signed work to add hires, rent, and paid lead spend?

Founder checklist

Don’t add rent, hires, or paid lead spend until signed or near-signed work can cover about $49.4K a month and the model still holds a 73% contribution margin. Keep launch setup near $72.5K, watch CAC at $2.5K in Year 1, and protect the $836K cash floor in Month 2.

1Signed Pipeline$49.4K/mo

Verify signed or near-signed work can cover this monthly revenue before you lock in office space or bigger hires.

2Fixed Base$6.7K/mo

Check the fixed base and the $72.5K launch build together, because those costs hit before break-even arrives.

3Margin Control73% CM

Hold subcontractors and usage-based tools in check so delivery stays near the 73% contribution margin.

4Team RampMonth 4-13

Add the senior consultant in Month 4, the data scientist in Month 7, and sales support in Month 13 only if demand can absorb them.

5Cash Cushion$836K

Keep reserves above the Month 2 low point and cover the $72.5K setup spend so the ramp does not force cuts.

6CAC Cap$2.5K

Track Year 1 CAC at or below this level and use clear scopes, deposits, and payment timing so paid acquisition stays profitable.
