Which sauna expenses are fixed, and which move with visits and sales?

Cost classification

At 60 visits/day and 350 operating days, small classification errors compound fast. Treat rent as fixed, visit-linked items as variable, and staffing as semi-fixed so the Month 4 break-even target reflects real capacity.

Expense	Cost	Break-Even Treatment	Common Mistake
Commercial Lease Rent	Fixed	Hold at $18,000 per month from Month 1 through Month 60.	Spreading rent per visit and hiding the true monthly hurdle.
Business Insurance	Fixed	Include as an $800 monthly overhead item before contribution margin.	Leaving it out because it does not change with sessions.
Utilities Electricity Water	Variable	Model at 4.0% of revenue in the first year, then apply the forecast percentages.	Treating heat, water, and power as pure fixed overhead.
Towel Laundry Service	Variable	Model at 1.5% of revenue because towel use follows visits.	Budgeting one flat laundry bill even as traffic rises.
Payment Processing Fees	Variable	Deduct 2.0% of revenue from each paid session or booking.	Counting gross sales as cash collected before card fees.
Retail Product Inventory Cost	Variable	Apply 3.0% of revenue to cover product inventory tied to retail sales.	Putting retail inventory in overhead and overstating margin.
General Manager Wages	Semi-fixed	Carry 1.0 FTE at an $85,000 annual salary before volume arrives.	Treating management payroll like a per-visit expense.
Front Desk Staff Wages	Semi-fixed	Step staffing from 2.0 FTE in the first year to 3.0 FTE by the third year.	Using one flat staffing level across all traffic volumes.

How does break-even shift from lean to full sauna demand?

Scenario table

Break-even risk falls as daily visits rise and the mix shifts toward multi-session packs. That lifts monthly revenue faster than variable costs, so the fixed lease and payroll are easier to cover.

Planning assumptions only; actual results will move with visit volume, sales mix, and cost control.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean opening-year demand	$103,250	$10,841	$43,792	89.5%	$48,617	Still above break-even, but the floor is about 28 visits a day.
Base Year 3 demand	$225,750	$23,261	$56,750	89.7%	$145,739	Break-even cushion widens as demand stays well above the floor.
Full mature-year demand	$315,000	$31,500	$57,750	90.0%	$225,750	Strong cushion; fixed costs are easy to absorb at this volume.

What pushes this sauna below break-even?

Stress test

Year 1 clears break-even, but the cushion shrinks fast if visits fall or overhead creeps up. The main risk is fixed payroll and utility pressure before demand is steady.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$48,929	$54,321 cushion	Year 1 clears break-even with room, but traffic must stay steady.
Revenue shortfall	Average daily visits fall 25% from 60 to 45.	$48,929	$28,509 cushion	A smaller visit base still covers break-even, but the buffer shrinks fast.
Fixed-cost pressure	Monthly fixed costs rise 10% to $48,171.	$53,827	$49,423 cushion	Extra rent or payroll eats cushion before sales do.
Margin pressure	Variable expenses rise to 15.0% of revenue.	$51,520	$51,730 cushion	Utility, laundry, or card fees can tighten the spread quickly.
Combined pressure	Visits fall 25%, fixed costs rise 10%, and variable expenses rise to 15.0%.	$56,672	$20,766 cushion	The model still clears break-even, but the margin is thin.

Can this sauna clear break-even before you sign the lease and start the build-out?

Founder checklist

The model reaches break-even by Month 4, but the real test is whether the lease, staffing, and launch spend still work when cash bottoms out in Month 7. If you cannot support about $48,929 in monthly break-even revenue and at least 28 visits a day, wait.

1Lease load$48.9K/mo

Check that the lease plus all fixed overhead still fits a $48,929 monthly break-even target before you sign.

2Visit floor28/day

Validate local demand can hold at least 28 daily visits in Year 1, since that is the floor needed to reach break-even volume.

3Blended yield$59/visit

Test the mix of single sessions, packs, private suites, and retail until revenue holds near $59 per visit, or margin slips fast.

4Utility load4.0%

Confirm electricity, water, and HVAC stay near the 4.0% Year 1 utility line, because sauna usage can push that cost higher.

5Launch crew$19.5K/mo

Make sure front desk, cleaning, and laundry coverage can run at about $19,542 a month, and that $4,000 of monthly marketing can still fill the opening schedule.

6Build cash$422K gap

Fund the $1.46M capex build plus the Month 7 cash gap of $422K, and lock ventilation, water filtration, security, and insurance before traffic ramps.
