Which advertising agency expenses are fixed, and which move with sales?

Cost classification

Break-even is Month 21, so the model has little room for sloppy cost grouping. Treat fixed overhead, headcount steps, and revenue-linked delivery costs separately or the sales target will look safer than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent	Fixed	Carry $3,500 per month in overhead from Month 1 through Month 60.	Allocating rent as a percentage of client revenue.
General Software Subscriptions	Fixed	Use $800 per month as baseline operating overhead for the planning range.	Moving all software into variable delivery expense.
Utilities & Internet	Fixed	Include $500 per month as recurring overhead before contribution margin.	Ignoring small fixed bills because they look immaterial.
Salaried Delivery Headcount	Semi-fixed	Model roles by planned FTE steps, including account manager, strategist, analyst, and creative specialist.	Treating all payroll as flexible when client work slows.
Freelance Creative Talent	Variable	Deduct as delivery COGS, starting at 8.0% of revenue in the first year.	Putting freelancers into fixed payroll instead of job-linked delivery expense.
Specialized Project Software Licenses	Variable	Apply as project-linked COGS, starting at 3.0% of revenue in the first year.	Assuming project tools stay flat as client volume grows.
Client Entertainment & Travel	Variable	Model at 5.0% of revenue in the first year, then lower as efficiency improves.	Budgeting travel as a fixed allowance with no sales link.
Remote Work Infrastructure & Tools	Semi-variable	Use the $250 monthly base, then review seat needs as client load and staffing rise.	Forgetting that tools can grow with people and active accounts.

How does break-even shift from a lean launch to a full agency setup?

Scenario table

As staffing grows, fixed payroll rises faster than the margin gain, so the revenue floor moves up. The lean model breaks even sooner; the full model has a better margin but needs much more monthly sales.

Planning figures only; actual results will move with client mix, pricing, and hiring pace.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch	$357k	$82k	$262k	77%	$13k	Stays about $16k above break-even.
Base agency	$527k	$112k	$389k	78.7%	$26k	Gives a solid cushion, but payroll lifts the floor.
Full agency	$722k	$141k	$539k	80.5%	$42k	Highest margin, but it needs the biggest revenue base.

What breaks this agency’s break-even plan?

Stress test

The plan breaks fastest if retainer sales ramp slowly, utilization stays low, or freelancers and commissions chew up gross profit. At the base case, the agency needs about $341k in annual revenue to cover $262k of fixed costs at a 77% contribution margin.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$341k	$0 cushion	Sales must hit the ramp on time.
Revenue shortfall	Revenue runs 10% below break-even.	$341k	$26k gap	Even a small miss can turn cash tight.
Fixed-cost pressure	Fixed costs increase 10%.	$375k	$34k gap	Overhead creep lifts the break-even target fast.
Margin pressure	Variable expenses rise from 23% to 28%.	$364k	$23k gap	Freelance use and commissions eat gross profit.
Combined pressure	Variable expenses rise to 28% and fixed costs increase 10%.	$401k	$60k gap	Slow sales plus higher overhead push the model out.

Is the agency ready for office rent and a bigger team?

Founder checklist

Before you commit to office rent and a bigger team, prove the agency can reach $34K-$36K in monthly revenue and keep about a 77% contribution margin. If the pipeline cannot support roughly 12 retainer-equivalent clients, or the $598K cash cushion is not real, wait.

1Revenue path$34K-$36K/mo

Verify the pipeline can support this monthly revenue so break-even does not depend on hope; that is roughly 12 Year 1 retainer-equivalent clients or an equal mix of retainers, projects, audits, and performance work.

2CAC budget$15K / $1.5K CAC

Check that $15K in Year 1 marketing can still buy qualified demand at about $1,500 per customer, or the funnel will miss the client count needed to fund the fixed base.

3Margin mix77% CM

Keep contribution near 77% after freelance creative talent, software, travel, and sales fees, because that margin is what makes the Month 21 break-even math work.

4Fixed load$6.65K/mo

Hold monthly fixed cost near $6,650, and delay the $3,500 rent if it tightens runway, since office overhead is the fastest way to turn a workable model into a cash drain.

5Staffing ramp2.0 FTE

Start with about 2.0 FTE, then add the analyst and creative specialist in Month 13 only when billings can absorb the step-up; capacity has to rise with revenue, not ahead of it.

6Cash runway$598K min

Keep at least $598K of cash available because break-even lands in Month 21 and payback takes 40 months, and the $52.5K launch setup spend is cash you need up front, not profit.
