Cost classification

Your break-even works only if fixed overhead and revenue-linked spend stay in the right buckets. In the first operating year, model base overhead separately from 7% software, 4% data tools, 9% commissions, and 8% ad spend.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent / Remote Stipends	Fixed	Use $2,500/month in monthly overhead.	Treating workspace spend as client-level delivery spend.
General Administrative Software	Fixed	Use $500/month in monthly overhead.	Mixing admin seats with per-client testing tools.
Legal & Compliance Fees	Fixed	Use $800/month in monthly overhead.	Adding one-time setup work to recurring break-even.
Core Year 1 Payroll	Fixed	Use about $32.1k/month for the CEO, senior specialist, analyst, and business development roles.	Treating salaried delivery capacity as fully variable.
Specialized Software Licenses	Variable	Use 7% of revenue in the first operating year.	Hiding per-client tools inside fixed subscriptions.
Third-Party Data Analysis Tools	Variable	Use 4% of revenue in the first operating year.	Forgetting data usage rises with active projects.
Sales Commissions & Performance Bonuses	Variable	Use 9% of revenue in the first operating year.	Pricing retainers before commissions are deducted.
Direct Marketing & Ad Spend	Variable	Use 8% of revenue in the first operating year.	Counting acquisition spend only as a fixed budget.

How does break-even change across lean, base, and full CRO operating models?

Scenario table

As staffing and software load rise, fixed costs climb faster than margin improves, so break-even revenue steps up in each model. The base case is the cleanest middle path for a steady agency build.

Planning-only figures; actual break-even will move with mix, pricing, and sales pace.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean founder-led CRO shop	$52.6K	$14.7K	$37.9K	72.0%	$0	Works with a small team, but the cushion stays thin.
Base agency build	$92.4K	$22.6K	$69.8K	75.5%	$0	Best middle path if the pipeline stays steady.
Full scaled delivery team	$123.9K	$27.3K	$96.6K	78.0%	$0	Needs the most volume, so underfilled capacity raises risk fast.

What breaks the break-even plan for a CRO agency?

Stress test

The plan has little shock room. A 10% revenue miss, a 10% fixed-cost jump, or a drop in contribution margin to 65% each creates a monthly gap; if two hit together, the shortfall is about $109K.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$526K	$0 gap	No cushion if any client slips.
Revenue shortfall	Monthly revenue drops 10% to $474K.	$526K	$38K gap	Slow close rates push cash below target.
Fixed-cost rise	Fixed costs rise 10% to about $417K.	$579K	$38K gap	Software overbuying and overhead raise the bar.
Margin pressure	Contribution margin falls to 65%.	$583K	$37K gap	Contractor overages before retainers are signed squeeze delivery profit.
Combined pressure	Revenue falls to $474K and margin drops to 65% while fixed costs rise to about $417K.	$642K	$109K gap	Churn before Month 19 turns the gap into a cash problem.

Is the CRO pipeline ready to support payroll, tools, and scale before you lock in break-even?

Founder checklist

Don’t commit to full hiring or platform spend until signed retainers can carry the Year 1 cost base. The test here is about 15 active client equivalents at roughly $36K each, plus enough launch cash to survive the $559K low point in Month 20.

1Client base15 x $36K

Verify the signed pipeline can reach about 15 active client equivalents at this value, because break-even stalls without enough recurring work.

2Fixed load$37.9K/mo

Check that the full office, software, compliance, training, and salary load can be covered by booked revenue, not by future growth hopes.

3Direct margin72% CM

Confirm software, data tools, commissions, and ad spend stay near the 28% direct cost stack so each dollar still leaves room for overhead.

4Hiring rampMonth 13+

Set utilization targets before adding specialist capacity, and delay the UX/UI hire until Month 13 unless revenue can justify the extra payroll.

5Cash cushion$559K / M20

Make sure launch cash can absorb the Month 20 low point, because a sales delay can force cuts before the business reaches payback.

6Growth spend$25K / $1.5K CAC

Keep Year 1 marketing tied to the $25K budget and $1,500 CAC target, so acquisition stays inside the cash plan.
