Cost classification

Break-even is reliable only when stable overhead stays separate from project-linked spend and hiring steps. In the first operating year, the model reaches break-even in Month 8, so misclassifying travel, rendering, or staff can move the target.

Expense	Cost	Break-Even Treatment	Common Mistake
Studio Rent ($6,500/month)	Fixed	Include as monthly overhead from Month 1 through the planning period.	Treating rent as project-driven when it stays due even in slow months.
Professional Liability Insurance ($1,200/month)	Fixed	Load into fixed overhead because coverage runs regardless of active project count.	Dropping it below break-even as if it only applies to signed projects.
BIM and CAD Software Licenses ($950/month)	Fixed	Model as stable monthly software overhead within the current staffing plan.	Classifying core design software as a variable project fee.
External Rendering and Visualization (8% of revenue in first year)	Variable	Apply as a revenue-linked project expense that falls to 6% by the mature year.	Locking consultant support into fixed overhead and overstating break-even risk.
Project Travel and Site Visits (5% of revenue in first year)	Variable	Tie to project volume because site work rises with active jobs and client locations.	Treating client pass-throughs and site travel as permanent fixed overhead.
Printing and Blueprint Services (3% of revenue in first year)	Variable	Calculate as a project-linked expense that declines to 1% by the mature year.	Using one flat monthly print budget even when project volume changes.
Specialized Accessibility Software Subs (4% of revenue in first year)	Semi-variable	Separate any base subscription from usage that tracks project volume and documentation needs.	Modeling the full amount as fixed when usage rises with billable work.
Project Manager salary ($85,000 annual salary; starts Month 7)	Semi-fixed	Add in steps when hiring expands delivery capacity, starting at 0.5 FTE in the first operating year.	Smoothing wages across all months instead of reflecting the Month 7 hiring step.

How does break-even shift from a lean studio month to a full-capacity project month?

Scenario table

Break-even moves fast when project mix, staff load, and overhead change. Lean months sit close to the line, the base case hits the model’s Month 8 break-even point, and fuller capacity adds a much wider cushion.

Planning cases only; actual break-even will move with scope, staffing, pricing, and project timing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean Year 1 studio month	$51K	$10.2K	$41.1K	80%	-$0.3K	Still slightly short, so small delays matter.
Base Month 8 break-even case	$54K	$10.8K	$43.2K	80%	$0	Hits the model’s Month 8 break-even line.
Full-capacity Year 5 case	$363.1K	$43.6K	$70.9K	88%	$248.6K	Strong cushion once backlog and staffing scale.

What breaks the break-even plan for an accessible design studio?

Stress test

Here’s the quick math: Year 1 margin is 80%, and fixed costs are about $493K a year, so break-even revenue is about $616K. The Year 1 plan at $612K leaves almost no cushion, and a slipped project or higher field costs can strain cash before Month 8.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change. Year 1 revenue is $612K at 80% contribution margin.	$616K	$4K gap	Cushion is thin before Month 8.
Revenue shortfall	One Year 1 project slips and revenue falls to about $438K.	$616K	$178K gap	Backlog delay quickly breaks cash.
Fixed-cost pressure	Annual fixed costs rise by $5K.	$622K	$10K gap	Higher overhead turns a small miss into a loss.
Margin pressure	Variable expenses rise from 20% to 25%, cutting contribution margin to 75%.	$657K	$45K gap	Extra site travel and printing eat the cushion.
Combined pressure	One project slips, fixed costs rise by $5K, and variable expenses rise to 25%.	$664K	$226K gap	Lower utilization and more field work hit cash before steady backlog.

Can you sign the studio lease only after the backlog and cash path clear break-even?

Founder checklist

Do not lock in fixed space until signed work can support the monthly run rate and the Month 8 cash low. The model only works if demand, pricing, and staffing all hold before rent and payroll stack up.

1Backlog$54K/mo

Verify signed work can support about $54K in monthly revenue before you commit to the lease, because fixed rent only works when demand shows up first.

2Contribution80% CM

Check that the $225 commercial, $175 residential, and $250 accessibility rates still clear the 80, 40, and 15 hour mix, so the modeled margin stays intact.

3Studio load$10.1K/mo

Keep studio rent and core overhead at this level only if the backlog can cover it before you add more fixed cost.

4Team ramp4.0 FTE

Confirm the Year 1 mix of 1.0 Principal Architect, 1.0 Senior Accessibility Designer, 1.0 Junior Architect, 0.5 Project Manager, and 0.5 Admin can handle the load before Month 7 hiring expands.

5Cash reserve$774K

Stress-test the Month 8 cash low, and do not treat booked revenue as cash in the bank, because the model still needs this reserve even with Year 1 revenue at $612K.

6Launch demand$25K / $2.5K CAC

At a $25K Year 1 marketing budget and $2.5K customer acquisition cost (CAC), you only get about 10 customer wins, so check the funnel before you commit more fixed cost.
