The IHT service line: a payback model for a single device.

We get a version of this question every week. What does the math look like on a HypoxBreath device — not in the marketing-deck sense, but in the boring spreadsheet sense? This post is that spreadsheet.

Nothing in here is a guarantee. Member behavior at your studio will not match the studio down the street. Treat this as a model — the structure matters more than the specific numbers.

The baseline assumptions#

• Device price: $38,500 (one HypoxBreath unit, plug-and-play).
• Session length: 40 minutes, plus a 10-minute changeover.
• Operating window: 10 hours per day, 6 days per week (52 weeks).
• Max theoretical slots per device per day: ~12.
• Session price tested: $90 / $115 / $150.
• Consumables and gas: estimated $4 per session.
• Staff cost per session: estimated $6 per session at light supervision.
• Variable cost total: $10 per session.

A few notes before the math. The 12-slots-per-day number is theoretical — no studio actually books 12 slots per device per day. Realistic utilization in the studios we've seen ranges from 2 to 6 booked sessions per device per day in the first year, climbing with awareness. The model below leans toward the middle of that range.

Payback by utilization#

The payback table below shows months to recover the device cost only — ignoring the membership uplift, ancillary sales, and the impact of having an unusual modality on the menu (all real, but harder to model).

Sessions / day	Price / session	Net revenue / day	Months to payback
2	$90	$160	60.2
2	$115	$210	45.8
2	$150	$280	34.4
4	$90	$320	30.1
4	$115	$420	22.9
4	$150	$560	17.2
6	$90	$480	20.1
6	$115	$630	15.3
6	$150	$840	11.5

Months to recover $38,500 at 26 operating days per month, $10 variable cost per session.

The midline of the table — 4 sessions per day at $115 — pays back in roughly 23 months. The slightly more confident operator booking 4 sessions per day at $150 lands in the 17-month window we cite in the device deck.

Where operators actually land#

Three patterns we've seen in the field:

• Hot studios in their first quarter. New service-line launches with good marketing energy tend to land at 5–6 sessions per device per day for a few weeks, then settle to 3–4 once the launch curiosity normalizes.
• Pre-existing recovery brands. Studios that already sell sauna, cold, red-light, or compression land near the steady-state midline of the table (4 sessions per day, $115–$150) faster — usually within the first two months — because their members already understand recovery modality pricing.
• Gym add-ons. Traditional gyms layering IHT on top of a membership product sometimes underbook in the first six months. The math still works at 3 sessions per device per day, but the operator has to push awareness internally.

The honest summary: most operators we see hit payback inside two years on a single device. A subset hit it inside a year. The variability is utilization, not pricing.

Pricing isn't the lever you think it is#

A common instinct, on a service line that's underbooked, is to drop the price. The model says don't.

At 2 sessions per day at $90, you pay back in 60 months. At 4 sessions per day at $90, you pay back in 30. Booking is the lever; pricing is not.

Cutting the price 20% to grow volume by 10% is a worse trade than holding the price and investing the same effort in awareness. The members who pay $115–$150 for a sauna session will pay $115–$150 for a hypoxic session if the experience is positioned correctly.

The exception is the explicit launch offer — a discounted first session for new members to lower the trial barrier. Operators we've seen do this well keep it time-limited, capped at one per member, and structured around an introduction protocol they can deliver consistently.

What's not in this model#

Three things the table above intentionally ignores:

• Membership uplift. A new modality changes member retention and average contract value. Both are real revenue lines, and both are harder to model without studio-specific data. Operators we work with typically see the uplift inside the first two quarters.
• Bundle revenue. Three-modality recovery packages (e.g., IHT + sauna + cold) typically command a 30–40% premium over the same modalities sold individually. That revenue belongs to the bundle, not to the IHT line, but it's a real effect.
• Brand differentiation. A studio with IHT on the menu shows up differently in search, in referrals, and in PR. Hard to model; not zero.
