Direct answer

A cryotherapy business case rests on how many paid sessions you actually deliver and what it costs to run the room - not on how many sessions the chamber could handle. The calculator above takes a base case and a downside case, each with a 24-month ramp and a downtime allowance. Every field starts blank, so no supplier's revenue projection stands in for your demand.

Calculation rules

Delivered paid sessions = booked sessions x (1 - cancellation rate) x (1 - downtime rate)

Delivered unpaid sessions = unpaid sessions/day x open days x (1 - downtime rate)

Net receipts = delivered paid sessions x revenue after discounts x (1 - refunded revenue share)

Variable cost = (paid + unpaid delivered sessions) x (consumables + direct labor) + delivered paid sessions x retained net transaction fees

Monthly operating contribution = net receipts - variable cost - monthly energy - service - overhead - marketing

Monthly cash flow = operating contribution - monthly finance payment

Cash recovery month = first nonnegative month-end cumulative cash, starting at negative initial cash outlay

Cancellations and refunds are different. A cancellation removes the booking before the session happens. A refund comes after delivery: it reduces receipts but doesn't give back the labor, supplies or retained fees already spent. Enter retained transaction fees after any fee refunds; cancellation-fee income isn't modeled.

Unpaid sessions don't follow the ramp. Trials and training sessions use supplies and staff time without revenue, and they stay separate from the paid-demand ramp. Because the model uses monthly averages, session counts can be fractional, unlike a real booking schedule.

Financing is counted once. Initial outlay is the cash you actually pay up front. Don't add the financed purchase price on top of its installments. Irregular deposits, loan proceeds and balloon payments go in the cash worksheet.

Break-even can slip back. The first month that ends with nonnegative cumulative cash can be followed by negative months, and it doesn't show whether cash covers every payment date within a month. Tax, depreciation and accounting profit need a separate, reviewed view.

04

Sensitivity view

The sensitivity table reruns the base case at 75%, 100% and 125% of booked demand with everything else held fixed. Treat these as stress tests, not probabilities. To test price, gas, labor or service changes, put them in the downside case. Costs don't scale automatically with utilization, so give each case its own energy or gas budget.

05

Common mistakes

  • Using the chamber's theoretical capacity as forecast demand.
  • Multiplying the list price by full opening hours, with no ramp or cancellations.
  • Leaving out owner labor, marketing, downtime or maintenance.
  • Entering supplier numbers without a label and date.
  • Hiding negative months or skipping the downside case.
06

Transfer utility totals without doubling them

Enter the full monthly gas bill plus the electricity budget for the same paid and unpaid workload, with no overlap between them. If you've calculated a full-bill cost per paid session elsewhere, don't multiply it by sessions and then add the bill again. Likewise, consumables and direct labor here should exclude anything already counted in monthly energy, service or overhead.

The optional scenario record keeps the model and configuration, measurements, tariff, dates, currency, calendar and cost boundary with your results. Notes you leave blank show as unknown in the CSV and printout; they never count as supplier verification. To compare two different cooling systems, use the matched technology worksheet.
