Which expenses are fixed and which move with sales for an oxygen bar?

Cost classification

Break-even only works if overhead is kept separate from visit-level spending. Here, every dollar of revenue carries 14% variable expense before covering rent, payroll, software, cleaning, and other monthly overhead.

Expense	Cost	Break-Even Treatment	Common Mistake
Commercial rent	Fixed	Use $3,000 per month as base overhead before any visit contribution.	Spreading rent across sessions too early and hiding low-traffic risk.
Utilities	Semi-variable	Start with the $500 monthly base, then test added usage if traffic rises.	Treating the full amount as visit-level spending.
General Manager payroll	Fixed	Include 1.0 full-time equivalent at $60,000 per year as monthly overhead.	Charging management payroll to each session like a supply item.
Oxygen Bar Attendant payroll	Semi-fixed	Model staffing in steps, from 1.5 full-time equivalents in the first year to 2.0 in the second year.	Assuming labor rises perfectly with each added visit.
Disposable supplies	Variable	Apply 2% of revenue as visit-linked goods used during sessions.	Leaving supplies in overhead and overstating contribution margin.
Retail product	Variable	Apply 6% of revenue tied to upsell and retail sales.	Counting retail sales without the matching product expense.
Marketing and advertising	Variable	Use 4% of revenue because the model scales spend with sales.	Treating all marketing as fixed and understating break-even visits.
Payment processing fees	Variable	Apply 2% of revenue because card fees move with paid sessions and retail sales.	Forgetting fees on upsells and making margins look cleaner than cash.

How do lean, base, and full traffic cases change break-even at an oxygen bar?

Scenario table

More visits turn Year 1 from a thin gap into clear profit by Year 2 and Year 3. The CM ratio, or contribution margin after variable costs, stays at 86%, so break-even is mostly a volume problem.

These are planning assumptions, not guarantees; actual traffic, mix, and labor can move the result.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean traffic case	$13.8k	$1.9k	$12.3k	86%	-$0.5k	Still near break-even, but a small monthly gap remains.
Base traffic case	$25.3k	$3.5k	$14.9k	86%	$6.8k	Past break-even, with room to absorb normal swings.
Full traffic case	$38.8k	$5.4k	$16.2k	86%	$17.2k	Well above break-even, so fixed costs are covered cleanly.

What breaks the break-even plan for an oxygen bar?

Stress test

The plan is most exposed to traffic softness, higher staffing, and rent creep. A small drop in visits or a 10% jump in overhead can turn a thin cushion into a real monthly gap.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change in visits, pricing, or cost load.	$166,000	$0 gap	Baseline only works if traffic holds.
Revenue shortfall	Year 1 traffic falls from 20 to 18 visits per day.	$166,000	$17,000 gap	Slow weekday traffic starts to drag cash.
Fixed-cost pressure	Monthly overhead rises 10% from about $148,000 to $163,000.	$189,000	$23,000 gap	Rent or attendant coverage can erase the cushion.
Margin pressure	Variable expenses rise from 14% to 18%, cutting margin to 82%.	$180,000	$14,000 gap	Weak retail upsell or higher fee drag lifts the sales bar.
Combined pressure	Traffic slips to 18 visits per day while overhead rises 10% and variable costs move to 18%.	$206,000	$40,000 gap	Traffic softness plus higher labor and rent leave a wide gap.

What should you verify before signing the lease for an oxygen bar?

Founder checklist

Test paid demand, room fit, and staffing before you lock the lease. The model breaks even in Month 14, so you need about 21 paid visits per operating day and tight control on the $129K build-out and early payroll.

1Demand Test21/day

Validate about 21 paid visits per operating day before you commit, because Year 1 assumes 20 visits a day and break-even only works if traffic gets there fast.

2Space Fit$129K capex

Confirm the site can hold oxygen concentrators, seating flow, cleaning paths, and POS hardware so the $129K build-out does not need rework after the lease starts.

3Unit Margin14% variable

Check supplier and processing pricing against the 2% disposable supply, 6% retail cost, 4% marketing, and 2% payment fee assumptions so contribution stays on plan.

4Staffing3.0 FTE

Keep Year 1 staffing at one manager, 1.5 attendants, and 0.5 cleaner FTE so payroll does not outrun the 20-visit base.

5Cash Buffer$762K min

Hold enough cash to cover the slow ramp, because the model's minimum cash point is $762K in Month 24 and Year 1 EBITDA is still negative $62K.

6Launch PaceMonth 14

Verify local rules on recreational oxygen, scented add-ons, waivers, signage, and advertising claims, then avoid extra hiring or spend until the Month 14 break-even point.
