Which sauna studio expenses are fixed and which move with sales?

Cost classification

Break-even gets unreliable when fixed rent, usage-driven fees, and step-up staffing are treated the same. Classify each expense by how it behaves as visits rise from 35 per day in the first year to 95 by Year 5.

Expense	Cost	Break-Even Treatment	Common Mistake
Commercial Rent	Fixed	Use $7,500 per month in the fixed overhead base.	Spreading rent per visit and making break-even look easier at low volume.
Utilities Electricity	Semi-variable	Model the $2,500 monthly amount as fixed, then stress test higher usage as visits climb.	Treating all power use as fixed when sauna room hours can rise with demand.
Retail Product Cost	Variable	Apply the product cost percentage to sales tied to retail purchases.	Putting retail margin into revenue without matching the product cost.
Session Amenities	Variable	Apply the amenities percentage to session revenue because towels and supplies follow visits.	Budgeting one flat monthly supply number while visits rise each year.
Payment Processing Fees	Variable	Apply 2.5% to processed revenue in every forecast year.	Leaving card fees out of contribution margin and overstating break-even progress.
Marketing Spend	Variable	Use the forecast percentage of revenue, from 8.0% in the first year to 4.0% in Year 5.	Keeping marketing flat even though the model ties it to revenue.
Sauna Attendant Staffing	Semi-fixed	Step labor up as coverage rises from 1.5 attendant FTE in the first year to 4.0 by Year 5.	Modeling attendants as fully variable per session instead of adding people in staffing steps.
Owner Operator Salary	Fixed	Include the $70,000 annual salary as recurring operating overhead.	Treating owner time as free labor and understating the true break-even point.

How does break-even shift from a lean launch to a base ramp and full-demand case?

Scenario table

Higher visit volume spreads rent, staffing, and software across more sessions, so the cushion widens fast. A bigger membership mix also keeps variable costs low.

Planning cases only; actual results will move with traffic, pricing, staffing, and cost control.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$490K	$69K	$271K	86%	$150K	Near break-even, but the cushion is thin.
Base ramp case	$700K	$95K	$296K	86.5%	$310K	This is the cleanest planning case for steady cushion.
Full-demand case	$1.03M	$131K	$329K	87.3%	$568K	Strong cushion here; break-even risk drops fast.

What breaks the sauna studio's break-even plan?

Stress test

The plan clears break-even in the first year, but the cushion is sensitive to a sales miss, higher rent, and rising power or payroll. A 20% revenue drop or a 5-point margin hit trims the buffer fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$316K	$151K cushion	Healthy cushion, but traffic still has to land.
Revenue shortfall	Revenue falls 20% to $392K.	$316K	$66K cushion	A 20% sales miss cuts the buffer fast.
Fixed-cost pressure	Fixed costs rise 10% to $298K.	$347K	$123K cushion	Rent and payroll creep push break-even higher.
Margin pressure	Variable expenses rise 5 points to about 19% of revenue.	$335K	$126K cushion	Higher electricity or amenity costs erode margin.
Combined pressure	Revenue falls 20%, fixed costs rise 10%, and variable expenses rise 5 points.	$368K	$20K cushion	Below 23 visits per operating day, the plan gets tight.

What should you verify before you sign the lease and open an infrared sauna studio?

Founder checklist

Treat this as a go or no-go check on cost, traffic, and cash. If the lease, staffing, and opening spend do not clear break-even on paper, the studio can look busy and still lose money.

1Opening Spend$257.5K

Verify the full launch bill for buildout, sauna suites, HVAC and electrical work, furnishings, laundry, initial retail stock, security, and booking setup stays near this level, because that cash leaves before revenue can smooth it out.

2Fixed Load$12.7K/mo

Verify rent, electricity, water, gas, insurance, software, cleaning, and supplies stay near this monthly base, because fixed costs hit every month no matter how full the schedule is.

3Throughput23/day

Verify the room plan and booking flow can support at least 23 visits per operating day, because the model starts at 35 visits a day and you want room if show rates slip.

4Margin Check86% CM

Here’s the quick math: retail cost, session amenities, marketing, and payment fees total about 14% of sales, so the studio keeps roughly 86% before fixed costs.

5Staffing Ramp$172.5K/yr

Lock the first-year staffing plan to a studio manager, one full-time attendant, one half-time attendant, and owner salary, because that is $172.5K a year before any growth hire.

6Cash Reserve$691K

The model reaches breakeven in Month 5, but cash still bottoms out at $691K in Month 6, so you need reserve money in place before opening.
