Which illustration expenses stay fixed, and which move with client work?

Cost classification

Break-even is only useful if each expense behaves the way the model says it does. Treat fixed commitments as fixed, and let revenue-linked items move with sales volume.

Expense	Cost	Break-Even Treatment	Common Mistake
Creative Software Subscriptions	Fixed	Carry as $150 per month from Month 1 through Month 60.	Cutting it from break-even because it feels small.
Shared Studio Space Rent	Fixed	Carry as $1,200 per month once committed.	Treating studio rent as optional after launch.
Accounting and Bookkeeping	Fixed	Carry as $250 per month across the planning period.	Leaving admin support out of the monthly hurdle.
Year 1 Marketing Budget	Semi-fixed	Model as $4,500 per first year, or about $375 per month.	Spreading spend evenly without checking lead flow.
Payment Processing Fees	Variable	Apply at 3.5% of revenue as client payments are collected.	Modeling fees as a flat monthly bill.
Project Specific Travel	Variable	Apply at 2.0% of first-year revenue when projects require travel.	Forgetting travel grows with client volume.
Freelance Artist Support	Variable	Apply at 8.0% of first-year revenue, rising with outsourced production work.	Calling support fixed even when it tracks project load.
Revision Allowance	Semi-variable	Keep a base allowance, then increase it when book scope or rounds expand.	Assuming every project uses the same revision time.

How does break-even change as this illustration service moves from lean to full staffing?

Scenario table

Break-even climbs as fixed pay and marketing rise. The lean setup carries the lightest load, the base case adds owner pay, and the full setup adds a junior illustrator, so billable capacity has to grow with payroll.

Planning assumptions only, not guarantees; client mix, billable hours, and staffing can move break-even.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean solo studio	$2,615	$405	$2,210	84.5%	$0	Lean overhead is the tightest cushion; one delayed project can swing the month.
Base owner-led studio	$10,012	$1,552	$8,460	84.5%	$0	About five blended projects cover the month, but owner pay is now the main drag.
Full studio with junior illustrator	$15,668	$2,900	$12,769	81.5%	$0	About seven projects are needed, so validate billable capacity before adding payroll.

What breaks the break-even plan for this illustration service?

Stress test

At the base plan, $10,390 of revenue leaves only a small cushion above the $10,012 break-even point. One lost project, a 5-point cost bump, or higher overhead can flip that cushion into a gap fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$10,012	$378 cushion	The base case clears break-even, but the cushion is thin.
Revenue shortfall	Lose one of five blended projects.	$10,012	$1,700 gap	One dropped project pushes the plan below break-even.
Fixed-cost pressure	Overhead rises 20% to $10,152.	$12,014	$1,624 gap	Higher studio and support costs need more booked work.
Margin pressure	Variable expenses rise 5 points to 20.5%.	$10,642	$252 gap	Small cost creep wipes out most of the cushion.
Combined pressure	Overhead rises 20% and variable expenses rise 5 points.	$12,772	$2,382 gap	Long revisions, extra travel, and slow deposits turn risky fast.

Is this illustration service ready for full-time spend, or should the founder wait until booked work clears break-even?

Founder checklist

Scale only after the portfolio proves the three offer types, deposits come in before sketching, and booked work clears the $8,460 monthly fixed load. At Year 1 rates, variable costs run about 15.5%, so contribution margin is about 84.5% and the real test is pipeline volume.

1Portfolio proof3 sample sets

Show full-book, cover, and educational samples so buyers can commit, then ask for deposits before sketching.

2Pricing margin84.5% CM

Check that Year 1 rates of $75, $90, and $70 an hour still leave room after 8.0%, 2.0%, 3.5%, and 2.0% variable costs.

3Inquiry cost$150 CAC

Keep each client win near the Year 1 acquisition cost so marketing does not outrun demand.

4Work volume5 blended/mo

Make sure booked work reaches roughly five blended projects a month before you call the model repeatable.

5Junior hireMonth 13

Delay the $50,000 junior illustrator until the lead schedule is full and overflow is steady enough to use the extra capacity.

6Cash buffer$876K

Hold enough cash for the Month 2 trough and do not add studio, gear, or marketing spend unless booked work also covers the $8,460 monthly fixed load.
