Cost classification

Break-even is only reliable if monthly overhead stays separate from procedure-linked spend. In the first operating year, fixed overhead starts at $53,800 per month before payroll, while variable items run at 16.5% of revenue.

Expense	Cost	Break-Even Treatment	Common Mistake
Facility Lease	Fixed	Include the $25,000 monthly lease as overhead from Month 1 through Month 60.	Spreading rent only across completed procedures.
Utilities	Semi-fixed	Use the $4,000 monthly base load, then review capacity pressure as operating room hours expand.	Ignoring higher utility demand at higher case volume.
Medical Malpractice Insurance	Fixed	Include the $10,000 monthly premium as recurring overhead in the break-even base.	Treating coverage as a per-case charge only.
Regulatory Compliance Fees	Fixed	Include the $2,500 monthly compliance fee from Month 1 through Month 60.	Delaying compliance spend until survey work starts.
Surgical Supplies	Variable	Model at 8.0% of first-year revenue, falling to 6.0% by the mature year.	Classifying supplies as fixed inventory.
Pharmaceuticals	Variable	Model at 4.0% of first-year revenue, falling to 3.0% by the mature year.	Averaging away high-use procedure mix.
EHR Transaction Fees	Variable	Model at 1.5% of first-year revenue, separate from the $3,000 monthly subscription.	Double counting the subscription and transaction fee.
Clinical Support Staff	Semi-fixed	Step FTEs from 2.0 in the first year to 6.0 in the mature year as volume scales.	Holding staffing flat while capacity rises.

How does break-even change from lean opening to base and full capacity at this surgical center?

Scenario table

Break-even gets safer as volume and utilization rise. Fixed overhead also rises, but revenue grows faster, so the full plan carries the widest cushion.

Planning assumptions only; actual break-even will move with case mix, payer mix, and staffing execution.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean opening	$1.35M	$222.8k	$105.5k	83.5%	$1.02M	Profitable, but it carries the thinnest cushion.
Base operating plan	$1.84M	$262.8k	$123.0k	85.7%	$1.45M	Reference case; break-even is covered with room to absorb normal swings.
Full capacity plan	$2.48M	$297.0k	$140.5k	88.0%	$2.04M	Strongest cushion, since higher volume spreads fixed costs best.

What breaks this surgical center's break-even plan?

Stress test

The plan has a real cushion at the current model, but it gets thinner fast if revenue slips, fixed overhead rises, or variable costs move up. The biggest warning signs are weak payer enrollment, slower referrals, and overtime or supply inflation.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$1,263k	$798k cushion	The base plan clears break-even, but the cushion is not endless.
Revenue shortfall	Cut Year 1 revenue by 20% to $1,649k.	$1,263k	$386k cushion	Lower case flow trims the cushion fast, so referral pace matters.
Fixed-cost pressure	Raise fixed overhead 20% to $1,266k.	$1,517k	$544k cushion	Lease, staffing, and compliance cost creep push break-even up.
Margin pressure	Lift variable expenses 5 points, from 16.5% to 21.5% of revenue.	$1,344k	$717k cushion	Supply inflation and overtime can eat margin even if volume holds.
Combined pressure	Cut revenue 20% to $1,649k, raise variable expenses to 21.5%, and lift fixed overhead to $1,266k.	$1,613k	$36k cushion	A small miss in payer enrollment or referrals could push it to the line.

Can this surgical center prove Month 1 break-even before you sign the lease and hire the full team?

Founder checklist

Month 1 break-even is not proof of demand; it only works if the center can support about $1.35M a month, keep cash above $849K, and bring the team and equipment online on time.

1Payer demand$1.35M/mo

Verify case volume and payer enrollment can support the $4,500 average reimbursement, because Year 1 revenue assumes about $1.35M a month from 300 case-equivalent units.

2Fixed load$100.1K/mo

Check that the $25K lease, $10K malpractice, and $46.3K of monthly payroll fit under the launch contribution, so fixed cost does not outrun collections.

3Contribution CM83.5% CM

Confirm the 12.0% COGS plus 4.5% variable cost stays near plan, because a small hit here moves break-even fast.

4Staffing ramp2/1/4/3/3

Verify 2 surgeons, 1 anesthesiologist, 4 OR nurses, 3 surgical techs, and 3 recovery nurses can actually cover the Month 1 schedule.

5Cash floor$849K

Keep cash above the $849K minimum while you fund the $3.345M capex build-out, or the launch can stall before collections catch up.

6Equipment timing$1.35M

Line up the $800K OR equipment, $300K anesthesia machines, and $250K sterilization gear before opening, so booked cases are not delayed.
