Cost classification

Break-even works only if $7,900 in monthly overhead is separated from Year 1 variable charges of 28% of revenue and semi-fixed payroll. Mix them up, and Month 6 break-even can look safer than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
Design studio lease	Fixed	Include $4,500 every month in overhead.	Signing a lease before pipeline proof.
Professional liability insurance	Fixed	Include $850 every month, even in slow months.	Treating required coverage as optional.
CAD and rendering software	Fixed	Include $600 monthly in overhead for baseline seats.	Ignoring seat creep as the team grows.
Professional portfolio photography	Fixed	Include $1,200 monthly, not just after new jobs.	Assuming it scales only with new projects.
Principal and staff salaries	Semi-fixed	Add payroll when capacity is committed; Year 1 core payroll is $317,500 annually.	Hiring before signed backlog supports the load.
Subcontractor management fees	Variable	Apply 12% of Year 1 revenue in the break-even model.	Treating delivery labor like overhead.
Direct material procurement costs	Variable	Apply 8% of Year 1 revenue and protect pass-through pricing.	Pricing projects without pass-through discipline.
Project-specific digital marketing	Variable	Apply 5% of Year 1 revenue, separate from the annual marketing budget.	Double-counting it against planned marketing spend.

How does break-even shift from a lean studio floor to a base year and full-capacity buildout?

Scenario table

The lean case sits on the edge, the base case adds a small cushion, and the full case has more profit but needs tighter staffing control. Break-even moves with signed design packages, oversight attachment, furnishing curation, and how well the team stays utilized.

Planning assumptions only; actual break-even will move with project mix, close rates, and staff use.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean studio floor	$50.6k	$14.2k	$36.4k	72%	$32	Near-zero cushion; one slow month can wipe it out.
Year 1 base case	$72.5k	$20.3k	$40.5k	72%	$11.7k	About $21.9k above break-even, so the cushion is real but not huge.
Year 5 full-capacity buildout	$533.3k	$106.7k	$80.4k	80%	$346.2k	Wide cushion if staffing and marketing stay controlled.

What could push this backyard living space design firm below break-even during ramp-up?

Stress test

Base monthly revenue of $72,500 clears the $50,600 break-even point by about $21,900. But slower deposits, extra site visits, unpaid revisions, or higher ad spend can erase that cushion fast if project timing slips.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$50,600	$21,900 cushion	The base plan clears break-even, but the cushion is not wide.
Revenue shortfall	Monthly revenue falls 20% to $58,000.	$50,600	$7,400 cushion	A 20% sales slip still covers break-even, but the cushion shrinks fast.
Fixed-cost pressure	Monthly overhead rises 10% to $40,100.	$55,700	$16,800 cushion	Lease and overhead creep eat room fast.
Margin pressure	Variable expenses rise from 28% to 35%, cutting margin to 65%.	$56,100	$16,400 cushion	More subcontractor, material, or travel cost pushes break-even higher.
Combined pressure	Revenue falls to $58,000 while variable expenses rise to 35% and overhead rises 10%.	$61,700	$3,700 gap	At $58,000, contribution misses fixed costs by about $2,400, so delay risk turns into loss.

Should you prove signed demand, margin, and cash before you commit to the studio lease?

Founder checklist

Don’t commit to the studio lease or the big showroom spend until lead flow, pricing, and cash all clear break-even. The model reaches break-even in Month 6, but only if you lock signed backlog early and keep rework from cutting the 72% contribution margin.

1Lead flow10 wins

Use the $25,000 Year 1 marketing budget and $2,500 CAC to prove you can win about 10 signed projects before you lock the lease.

2Fixed load$34.4K/mo

The lease, software, photography, utilities, admin, and Year 1 payroll add up to about $34.4K a month, so the pipeline has to cover that before you commit.

3Margin mix72% CM

Keep the 40-hour custom package at $175 per hour, 75% oversight at 60 hours and $150 per hour, and 40% furnishing at 15 hours and $125 per hour, or rework will shrink the 72% contribution margin.

4Staffing ramp3.5 FTE

Check that the principal, project manager, junior designer, and half-time admin can cover Year 1 demand at 12.5 billable hours per active customer before you add the procurement specialist in Month 13.

5Cash floor$785K

Keep enough cash to reach the Month 2 low point, since the model’s minimum cash need is $785,000 before it starts to recover.

6Launch timingMonth 6

Defer the showroom, vehicle, and visualization spend until backlog is real, keep site visits and contractor coordination on a weekly cadence, and remember the capex stack is about $116.2K with break-even landing in Month 6.
