Cost classification

Classify costs before you trust the break-even date. If fixed payroll is modeled as project spend, the Month 6 break-even point can look safer than the cash plan really is.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent	Fixed	Include $5,000 per month in fixed overhead.	Tying rent to project count or billable hours.
Professional Liability Insurance	Fixed	Include $1,200 per month before contribution margin.	Leaving required coverage out of break-even.
Principal Architect, Senior Architect, Architectural Designer, Office Manager salaries	Semi-fixed	Model launch payroll at about $31.7K per month, then step up as staffing grows.	Treating committed salaries like project-only labor.
Specialized Project Software Licenses	Variable	Apply 4.0% of revenue in the first year, falling to 3.0% by mature scale.	Treating all software as fixed office overhead.
Third-Party Project Consultants	Variable	Apply 6.0% of revenue in the first year for outside project support.	Forgetting consultants when pricing full-service design work.
Project-Specific Travel & Site Visits	Variable	Apply 3.0% of revenue in the first year, tied to active project work.	Spreading site visit spend evenly across quiet months.
Marketing & Business Development (Project-based)	Variable	Apply 7.0% of revenue in the first year for project-linked selling activity.	Mixing project-based spend with the committed annual marketing budget.
Annual Marketing Budget	Semi-fixed	Spread the $15K first-year budget as about $1,250 per month unless campaigns are paused.	Counting it only when a new client signs.

How does break-even change across lean, base, and full-service architectural firm setups?

Scenario table

Break-even climbs as fixed payroll rises and variable load stays high. Lean is closest to Month 6 break-even; base and full-service need more signed backlog and stronger utilization to keep the same cushion.

Planning ranges only; actual break-even will move with scope, staffing, and close rate.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean studio	$518K	$104K	$415K	80%	-$1K	Near break-even; cost drift hurts fast.
Base practice	$854K	$149K	$704K	82.5%	$0	Balanced path if backlog stays signed.
Full-service firm	$1,037K	$156K	$881K	85%	$0	Best only with high utilization and close rates.

What breaks the break-even plan for an architectural firm?

Stress test

Year 1 break-even is fragile because fees, payroll, and consultant pass-throughs all sit close to the line. A 15% revenue miss creates about a $62K gap, and a 10% fixed-cost rise or 25% variable load pushes break-even above $550K.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change in the Year 1 base case.	$518K	$0 gap	The firm only clears fixed costs at plan.
Revenue shortfall	Revenue lands 15% below break-even at about $441K.	$518K	$62K gap	A delayed award quickly turns into a cash hole.
Fixed-cost increase	Fixed costs rise 10% to about $456K.	$570K	$42K gap	Higher rent or payroll pushes the line up fast.
Margin pressure	Variable expenses rise to 25% of revenue.	$553K	$27K gap	More consultant pass-throughs cut contribution margin.
Combined pressure	Revenue is 15% short, fixed costs are 10% higher, and variable expenses are 25%.	$608K	$125K gap	Discounted fees and delayed awards can blow past break-even.

Can this architectural firm lock in fixed costs and still clear break-even?

Founder checklist

Only if signed or highly probable work can reach about $50.3k in monthly sales, or about $60.3k with a 20% cushion. The model hits break-even in Month 6, so don’t lock in fixed costs until demand and cash both clear that bar.

1Demand Proof$50.3k/mo

Verify the pipeline can support this monthly run rate before you sign fixed commitments, because that is the break-even sales floor in Year 1.

2Fixed Load$40.2k/mo

Check that rent, liability insurance, telecom, admin software, office costs, and other base spend stay inside this monthly burden, since it hits before project revenue.

3Contribution Margin80% CM

Keep the 4% project software load, 6% consultant spend, 3% travel, and 7% project marketing near 20% of revenue, or the margin that funds break-even shrinks fast.

4Staffing Ramp$31.7k/mo, 80 hrs

Make sure the Year 1 team cost and the 80 billable hours per active customer are realistic, because the plan fails if headcount grows faster than workload.

5Cash Buffer$807k floor

Hold enough cash for the Month 2 trough and the $76.5k setup spend, or the firm can run out of runway before the break-even point arrives.

6Launch Demand$15k, $1.5k CAC

Use the Year 1 marketing budget to prove lead flow, and check that customer acquisition still lands near the $1,500 CAC so launch demand does not outrun payback.
