Which float tank center expenses are fixed, and which move with sales?

Cost classification

Break-even only works if fixed overhead and session-driven costs are separated cleanly. Here, $10,400 in monthly facility overhead stays fixed, while salt, filtration, and card fees reduce contribution on every booked float.

Expense	Cost	Break-Even Treatment	Common Mistake
Commercial Facility Rent	Fixed	Include $6,500 per month in fixed overhead before session volume.	Spreading rent per float and missing the occupancy risk.
Marketing and Local SEO	Fixed	Include $1,800 per month as a recurring overhead line.	Treating the full budget as sales-based acquisition spend.
Insurance and Liability	Fixed	Include $450 per month regardless of daily visit count.	Leaving it out because it feels small.
General Manager and Lead Float Facilitator	Semi-fixed	Model as baseline staffing that stays in place until operating scale changes.	Calling all payroll variable just because labor supports sessions.
Customer Service Associate staffing	Semi-fixed	Step up staffing as average visits rise from 12 to 24 per day.	Adding labor smoothly instead of in real hiring steps.
Maintenance Technician	Semi-fixed	Increase staffing when tank usage and facility workload justify more coverage.	Ignoring the jump from 0.5 FTE to 1.0 FTE.
Epsom Salt and Water Chemicals	Variable	Deduct the modeled session-linked charge before contribution margin.	Treating salt and chemicals as harmless supplies.
Utilities and Water Filtration	Variable	Deduct usage-driven filtration and utility expense as float volume rises.	Missing that every session uses water, heat, and filtration.

How does break-even change from a lean float center to a full membership-led setup?

Scenario table

Higher visits and a heavier membership mix spread rent and payroll across more sessions, so break-even moves only a little while cushion improves. The model is more sensitive to utilization than to price.

Planning cases only; actual results will shift with demand, staffing, and pricing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean float studio mix	$33.8k	$5.9k	$25.7k	82.6%	$2.2k	Only a thin cushion above break-even, so slow weeks matter.
Base membership mix	$75.9k	$8.8k	$29.1k	88.5%	$38.1k	Break-even sits well below sales, so the cushion is strong.
Full repeat-demand mix	$97.8k	$9.2k	$31.7k	90.6%	$57.0k	Best cushion here, because repeat demand covers fixed costs fast.

What breaks the break-even plan if bookings slip, costs rise, or discounts get deeper?

Stress test

Year 1 starts with about a $30,000 cushion above a $308,000 break-even point. A 10% booking drop, a $10,000 fixed-cost step-up, or a $5 discount can erase that cushion fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change in bookings, fixed costs, or pricing.	$308,000	$30,000 cushion	The base plan has room, but not much.
Revenue shortfall	Revenue falls 10% from the base plan.	$308,000	$4,000 gap	A small demand dip turns the cushion negative.
Fixed-cost pressure	Fixed costs rise by $10,000.	$320,000	$18,000 cushion	Rent, staffing, or overhead growth cuts the buffer fast.
Margin pressure	A $5 discount cuts average revenue per visit.	$325,000	$13,000 cushion	Discounts weaken session margin and raise the load.
Combined pressure	Revenue falls 10%, fixed costs add $10,000, and discounting trims $5 per visit.	$337,000	$1,000 gap	Small misses stack up and push the plan to the edge.

What should you verify before signing the lease and funding the float tank buildout?

Founder checklist

Verify the lease, buildout, and staffing can work at 12 visits a day in the opening year, not later-year volume. If the site cannot cover the roughly $25.7K monthly fixed load and the $465.5K setup, wait before you commit.

1Demand Proof12/day

Confirm local demand can support 12 visits a day in the opening year before you plan for later-year volume.

2Fixed Load$25.7K/mo

Check that the $6,500 rent plus wages and overhead can fit under month-one cash flow, because fixed costs run about $25.7K a month before variable spend.

3Session Margin$68.5/session

Test the single-session math so the $85 price leaves enough room after the listed $16.50 of variable costs to fund the fixed load.

4Turnover Flow12/day

Map staff coverage and room turnover so salt handling, towel service, cleaning, and reset time still support 12 visits a day at launch.

5Buildout Spec$465.5K setup

Verify drainage, humidity control, sound isolation, ventilation, electrical capacity, plumbing, and shower scope before the $465.5K setup, including the $125K tanks and $45K filtration.

6Cash Runway$572K / 324 mo

Make sure you can hold the $572K cash low by Month 10 and pre-sell enough memberships and packages to reach 324 monthly sessions, about 11 visits a day, before opening.
