Which clinic expenses stay fixed, and which move with treatment volume?

Cost classification

Break-even is only useful if each expense behaves the way the model says it does. Treat rent as fixed, consumables as variable, and capacity investments separately so per-treatment margins don’t look better or worse than reality.

Expense	Cost	Break-Even Treatment	Common Mistake
Clinic Facility Rent	Fixed	Use the $12,500 monthly rent as a fixed monthly hurdle before contribution margin covers profit.	Spreading rent per treatment and hiding occupancy risk when volume drops.
Laser Equipment Maintenance Contracts	Fixed	Include the $4,500 monthly contract in fixed overhead across the relevant planning range.	Treating maintenance as if it rises with every treatment.
Medical Malpractice Insurance	Fixed	Model the $3,200 monthly premium as fixed unless the policy changes with provider count.	Linking insurance to revenue instead of coverage needs.
Medical Consumables and Laser Tips	Variable	Apply the Year 1 rate of 6.5% of revenue, falling to 5.0% by the mature year.	Forgetting that each session uses supplies even when pricing changes.
Clinical Supplies and Post Care Kits	Variable	Use the revenue-linked rate: 3.5% in the first year and 2.5% from Year 3 onward.	Budgeting kits as a flat office supply line.
Digital Marketing and Patient Acquisition	Variable	Model as a sales-linked expense, starting at 9.0% of revenue and declining to 6.0% by Year 5.	Calling marketing fixed when patient flow still depends on paid acquisition.
Merchant Fees and Financing Commissions	Variable	Apply the rate to collected revenue: 4.0% in Year 1, tapering to 3.0% by Year 5.	Leaving payment fees out of contribution margin.
Clinic Manager and Billing and Coding Officer payroll	Semi-variable	Keep the base roles in overhead, then step up when FTEs rise, such as billing moving from 1.0 to 1.5 FTE in Year 4.	Treating all payroll as fixed even when staffing changes with volume.

How does break-even change across lean, base, and full treatment schedules?

Scenario table

Break-even gets easier as volume rises because fixed costs stay fairly steady while each treatment adds high contribution dollars. The lean schedule is close to the line, but the base and full schedules cover overhead and build cushion.

Planning assumptions only; actual break-even will move with staffing, treatment mix, and patient flow.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean opening schedule	$26.3k	$6.0k	$25.5k	77.0%	-$5.3k	Still below fixed cost coverage, so launch risk stays high.
Base Year 1 plan	$137.5k	$31.6k	$25.5k	77.0%	$80.3k	Covers fixed costs in Year 1 and leaves a solid cushion.
Full Year 2 schedule	$227.8k	$47.4k	$29.3k	79.2%	$151.1k	Higher volume widens the cushion, so small price moves matter less.

What breaks the break-even cushion for a port wine stain laser clinic?

Stress test

The base plan clears break-even, but the cushion narrows fast if revenue slips or fixed payroll rises. The biggest risk is weaker referrals plus heavier paid acquisition, which push the clinic toward a $600k-plus break-even floor.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change from the base plan.	$602k	$773k cushion	Base case is comfortably above break-even.
Revenue shortfall	Revenue drops 20% to $1.1m.	$602k	$498k cushion	Demand softens, but the clinic still clears break-even.
Fixed-cost pressure	Fixed overhead plus admin payroll rises 15% to $533k.	$692k	$683k cushion	Overhead growth cuts the cushion fast.
Margin pressure	Variable expenses rise from 23% to 28%.	$644k	$731k cushion	Higher acquisition or supply costs erode margin cover.
Combined pressure	Revenue drops 20%, variable expenses rise to 28%, and fixed burden rises 15%.	$740k	$360k cushion	This is the stress case to watch; the cushion shrinks hard.

What should the founder verify before signing the lease and buying equipment for this clinic?

Founder checklist

Prove the opening volume, pricing, staffing, and cash cushion before you commit. The model shows Month 1 breakeven on paper, but that only holds if Year 1 demand lands and the Month 4 cash need is covered.

1Demand floor119/mo

Verify you can ramp to 270 average monthly treatments in Year 1, because the all-in break-even floor is 119 treatments a month and anything below that leaves the fixed base exposed.

2Price mix$509

Test the $509 average session revenue against payer mix and cash-pay pricing, because a weaker mix cuts revenue per treatment fast.

3Fixed load$24.25K/mo

The listed fixed costs total $24,250 a month, before provider pay and treatment variable cost, so the lease has to fit that load first.

4Core coverage1-1-1-1

Before launch spend, lock one lead dermatologist, one senior laser technician, one junior laser technician, and one registered nurse so the opening schedule can run.

5Room use65/50/45/40%

Check Year 1 utilization at 65%, 50%, 45%, and 40% for the lead dermatologist, senior technician, junior technician, and registered nurse, or the room plan won't support the volume target.

6Cash reserve$478K

Keep at least $478,000 through Month 4, cover the $735,000 capex across laser systems, fit-out, imaging, furniture, IT, furnishings, and safety inventory, and only market after malpractice, HIPAA, billing, coding, and referral workflows work.
