Cost classification

Your break-even is only reliable if rent and payroll stay fixed while disposables, laundry, and amenities move with booked treatments. Misclassifying a $10,000 monthly lease or 5.0% disposable load can make Month 13 break-even look safer than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
Commercial Rent	Fixed	Use $10,000/month from Month 1 to Month 60 as baseline overhead.	Treating lease payments as volume-based.
Utilities and Water	Semi-variable	Start with the $1,800/month baseline, then watch usage as capacity rises from 60.0% to 85.0%.	Ignoring higher water use at fuller booking volume.
Single-use Tubing and Speculums	Variable	Model as 5.0% of revenue in the first year, falling to 4.0% by the mature year.	Burying treatment disposables inside general supplies.
Disposable Herbal Infusions and Probiotics	Variable	Apply 2.5% of revenue in the first year, stepping down to 1.5% by the mature year.	Pricing treatments without the add-on consumables.
Per-treatment Laundry and Cleaning	Variable	Use 1.5% of revenue in the first year, declining to 1.0% as volume improves.	Missing sanitation load per booked session.
Website Hosting and Software	Fixed	Keep $400/month in overhead from Month 1 to Month 60.	Tying software expense to each treatment.
Clinic Manager and Front Desk Receptionist	Fixed	Include $178,000/year, or about $14,833/month, before other support roles.	Assuming payroll flexes with no-shows.

How does break-even shift from a lean opening mix to a fuller clinic schedule?

Scenario table

The model reaches break-even in Month 13, not in the launch month. Lean stays tight, base builds a clear cushion, and full gives the strongest profit buffer as utilization and pricing improve.

Scenario figures are planning assumptions, not guarantees, and they can move with booking pace, staffing, and pricing mix.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean opening mix	$41.8k	$4.1k	$37.5k	90.2%	$0.1k	Close to break-even, so a small booking dip hurts.
Base year-2 mix	$85.7k	$7.9k	$40.0k	90.8%	$37.8k	Clear cushion, with room to absorb slower demand.
Full year-3 mix	$128.8k	$10.8k	$42.4k	91.6%	$75.6k	Strong cushion, so profit can grow faster than overhead.

What breaks the break-even plan if bookings slip or costs rise?

Stress test

The clinic reaches break-even in Month 13, but the cushion is thin. A 10% booking miss, higher fixed overhead, or a small margin slip can push the plan back into a monthly gap fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$416k	$0 cushion	Month 13 break-even leaves little slack.
Revenue shortfall	Year 1 monthly revenue falls 10% to about $376k.	$416k	$36k gap	No-shows or discounting can widen the gap fast.
Fixed-cost pressure	Fixed overhead rises 10% to about $413k.	$458k	$40k gap	Rent-heavy overhead needs demand proof first.
Margin pressure	Variable expenses rise from 9.8% to 12.3% of revenue.	$428k	$10k gap	Small supply and cleaning leaks still move the floor.
Combined pressure	Revenue falls 10%, variable expenses rise to 12.3%, and fixed overhead rises 10%.	$459k	$83k gap	Weak bookings and higher costs leave little room to recover.

Can this clinic clear break-even before you sign the lease?

Founder checklist

Before you lock in rent, hiring, or equipment, make sure the opening ramp can support the model’s break-even load. The plan needs about 323 paid treatments a month, with Month 13 as the payback point and a Month 12 cash low of $761K.

1Demand proof323/mo

Verify you can book about 323 paid treatments a month before you count on break-even, or the Month 13 payback slips.

2Price ladder$95-$200

Test acceptance across the junior, certified, senior, and master price points, because weak pricing at the top or bottom changes revenue fast.

3Fixed load$37.5K/mo

Do not lock a $10K rent without a booking ramp, since base salaries and overhead lift fixed cost to about $37.5K a month.

4Team ramp2-3-1-0-1

Confirm the Year 1 practitioner plan of 2 junior, 3 certified, 1 senior, 0 lead, and 1 master so capacity matches the forecast.

5Setup capex$163K

Budget the full setup stack across equipment, furniture, renovation, POS, supplies, signage, security, and computers, and lock sanitation, laundry, and supply steps before marketing spend.

6Cash floor$761K

Hold this cash through Month 12, because the model’s low point sits there and Year 1 volume is only about one treatment above calculated break-even.
