Monthly revenue Revenue is the cash pool that covers direct costs and fixed overhead. $ Low sales High sales Variable expenses These are direct project costs that rise as billings grow. $ Light direct costs Heavy direct costs

Money available to cover fixed costs $43,800 $53,800 revenue - $10,000 variable expenses

Which expenses are fixed, and which move with project volume in a BIM service?

Cost classification

Break-even is reliable only if each expense behaves the right way. In this model, Month 18 break-even depends on keeping fixed overhead separate from project delivery costs that rise with revenue.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent	Fixed	Use $3,500 per month from Month 1 through Month 60.	Flexing rent with revenue instead of treating it as monthly overhead.
Core BIM Software Licenses	Fixed	Use $1,200 per month unless licensed seats expand.	Modeling core licenses as a per-project charge too early.
Cloud Services & Data Storage	Semi-variable	Use the $300 monthly base, then add usage if model files and storage needs grow.	Ignoring storage growth as larger projects add files and revisions.
Project-Specific Software Licenses	Variable	Apply 5.0% of first-year revenue, falling to 3.0% by the fifth year.	Putting project licenses in overhead instead of delivery expense.
Third-Party Data & Content Libraries	Variable	Apply 3.0% of first-year revenue, falling to 2.0% by the fifth year.	Treating content libraries as fixed when usage follows project scope.
Project-Related Travel & Accommodation	Variable	Apply 4.0% of first-year revenue, falling to 3.0% by the fifth year.	Spreading travel evenly across months instead of tying it to active projects.
Subcontracted Specialist Services	Variable	Apply 8.0% of first-year revenue, falling to 6.0% by the fifth year.	Treating subcontractors as overhead instead of project delivery expense.
Coordinator, Project Manager, Sales, and Admin Roles	Semi-fixed	Add payroll in staffing steps as full-time equivalent levels rise after the first year.	Hiring ahead of billable utilization and pushing break-even later.

How does break-even shift from a lean founder-led setup to a base Year 1 team and a fuller Year 2 team?

Scenario table

Break-even climbs quickly as the model moves from lean, to the Year 1 base team, to the fuller Year 2 team, because fixed payroll rises faster than variable costs fall from 20.0% to 18.6%. At $110 to $144 hourly rates, signed pipeline matters more than headcount.

Planning assumptions only. Actual break-even will move with signed work, billable hours, and fee rates.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean founder-led model	$235K	$47K	$188K	80.0%	$0	Very little cushion; any slip in signed work pushes this back into loss.
Base Year 1 delivery team	$329K	$65.8K	$263.2K	80.0%	$0	This is the first realistic break-even line for the planned team, so utilization has to stay tight.
Full Year 2 staffing mix	$515K	$95.9K	$419.1K	81.4%	$0	Higher capacity only works if the pipeline stays full enough to cover the larger payroll.

What happens if revenue slips, fixed costs rise, or project margin gets squeezed?

Stress test

The plan is tight: at $329K monthly revenue and $263K fixed costs, there’s no cushion. A 10% revenue dip creates about a $26K monthly gap, while higher subcontractor, travel, and software spend can push break-even above $351K.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$329K	$0 cushion	Any slip in hours or collections turns it negative.
Revenue shortfall	Monthly revenue falls 10% to about $296K.	$329K	$26K gap	Lower project intake hits cash right away.
Fixed-cost pressure	Fixed costs rise 10% to about $289K.	$362K	$33K gap	More seats, rent, or labor raise the bar.
Margin pressure	Variable expenses rise from 20% to 25%.	$351K	$16K gap	More subcontracting and travel squeeze project margin.
Combined pressure	Revenue falls 10%, fixed costs rise 10%, and contribution margin drops to 75%.	$386K	$67K gap	Volume and margin pressure together can break cash quickly.

What should a BIM founder verify before signing the office lease or adding staff?

Founder checklist

Don’t sign the lease or add hires until you have signed or near-signed pipeline above the $329K monthly break-even line. Confirm Year 1 pricing, utilization, and QA/file control too, because break-even lands in Month 18 and payback takes 33 months.

1Pipeline Proof$329K/mo

Verify signed or near-signed work can cover the $329K monthly break-even revenue before you commit to space or headcount.

2Rate Card$110-$140/hr

Test Year 1 client acceptance of $120/hour for BIM Modeling, $130/hour for Clash Detection, $110/hour for Construction Documentation, and $140/hour for On-Demand Project Support.

3QA Workflow40 billable hrs

Verify the first-year workload can stay at 40 BIM Modeling billable hours, and lock QA and file control now so rework does not burn margin later.

4Hiring RampMonth 13

Hold the BIM Coordinator, Project Manager, and Marketing & Sales Lead until Month 13 demand is real, so new payroll follows work instead of chasing it.

5Fixed Load$6.75K/mo

Keep non-payroll fixed costs near $6,750 per month, and question the $3,500 rent if remote delivery can cover the same output.

6Cash Runway$734K

Hold enough cash for the $53.5K setup spend and the Month 18 trough, because minimum cash peaks at $734K and payback takes 33 months.
