Which expenses are fixed, variable, semi-variable, or semi-fixed for virtual surgery simulation training?

Cost classification

Break-even lands in Month 2, but that only holds if fixed overhead, delivery load, and support scaling are split cleanly. Misclassifying usage-driven items as fixed will overstate margin as adoption grows.

Expense	Cost	Break-Even Treatment	Common Mistake
R and D Center Rent	Fixed	Include $12,000 per month in the fixed overhead base.	Spreading it across each client and hiding the true monthly hurdle.
Software Development Tools	Fixed	Include $3,500 per month before calculating contribution margin.	Assuming tools rise with revenue when the model treats them as stable.
Legal and Patent Maintenance	Fixed	Include $5,000 per month as recurring operating overhead.	Leaving it out because it feels non-operating.
Insurance and Liability	Fixed	Include $4,000 per month in the break-even fixed base.	Treating it as optional even though it runs from Month 1 to Month 60.
Year 1 Wages	Fixed	Use $815,000 per year, or about $67,917 per month, as core payroll overhead.	Modeling payroll only after sales when the team starts in Month 1.
Cloud Hosting and Data Storage	Variable	Apply 6% of revenue in the first year, falling to 4% by mature scale.	Calling hosting fixed and missing the load from more simulations and users.
Hardware Provisioning and Logistics	Variable	Apply 8% of revenue in the first year, falling to 6% by mature scale.	Treating headset logistics as fixed when they rise with adoption.
Medical Expert Review Fees	Variable	Apply 4% of revenue in the first year, falling to 2% by mature scale.	Locking review work into overhead instead of tying it to paid usage.

How does break-even move from lean pilots to hospital rollouts and full contract volume?

Scenario table

Break-even gets easier as the customer mix shifts from medical school pilots to hospital systems and device partner contracts. Lower variable cost share means more of each dollar stays to cover fixed overhead.

Planning view only: scenario figures use the model assumptions and are not guarantees.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean medical school pilot	$140k	$32k	$107k	77%	$0	At this scale, break-even is tight and one weak month can turn cash negative.
Base hospital rollout	$361k	$83k	$118k	77%	$160k	Year 1 clears break-even, but sales speed still matters because overhead stays heavy.
Full device partner contract case	$1.88m	$319k	$237k	83%	$1.32m	Higher margin gives a wide cushion, and break-even drops far below run-rate revenue.

What breaks the break-even plan for virtual surgery training?

Stress test

Base break-even is about $140,000 a month, driven by $107,000 in fixed overhead and a 77% contribution margin. The biggest risks are slower residency program procurement, a 5-point margin slip, and fixed-cost creep.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$140,000/month	$0 cushion	Lead flow must stay on pace.
Revenue shortfall	Monthly revenue lands 15% below target.	$140,000/month	$16,000 gap	Slow residency procurement shows up fast.
Fixed-cost increase	Fixed overhead rises 20%.	$149,000/month	$9,000 gap	Salary or facility creep raises the floor.
Margin pressure	Variable expenses rise from 23% to 28%.	$167,000/month	$27,000 gap	Heavier headset logistics or instructor support lifts the floor.
Combined pressure	Variable expenses rise to 28% and fixed overhead rises 20%.	$179,000/month	$39,000 gap	Procurement delays plus higher support costs can break the plan.

What should a founder verify before committing to the first big VR surgery training build?

Founder checklist

Don’t commit to the full build yet. Prove the buyer mix, pricing, funnel, and cost base can clear the $94.9K monthly load and the $797K cash dip before you lock in the $310K capex and heavier hiring.

1Buyer Demand3 buyer types

Ask academic, hospital, and device partner buyers if they will pay the $2,500, $5,000, or $12,000 monthly tiers and the $15K, $25K, or $50K one-time fees before you scale the platform.

2Fixed Load$94.9K/mo

Check that monthly rent, tools, legal, insurance, admin, and Year 1 salaries clear this base load, because break-even stays weak if early revenue cannot cover it fast.

3Margin Check77% CM

Confirm Year 1 cloud, hardware, sales commission, and expert review costs stay near 23% of revenue, so contribution margin holds near 77% and does not slip before payback.

4Hire Gate5-core roles

Hire against signed pipeline, not hope, and only scale past the Year 1 core team when booked deals justify the VR engineer, 3D artist, sales, and customer success ramp.

5Cash Buffer$797K low

Hold enough cash for the Month 2 low point, since the model pays back in Month 5 and that gap is where a good launch can still run out of room.

6Funnel Test$1.5K CAC

Before the $150,000 Year 1 marketing budget goes live, test whether a 5.0% visitor-to-lead rate and a 10.0% lead-to-paid rate can really support CAC near $1,500.
