Most people evaluating a cash-pay metabolic wellness program ask the wrong first question — "how much does it make?" — when the useful first question is "what does one enrolled patient cost to serve, and how many can this room physically hold?" This article gives you the arithmetic for both. Every variable below is left blank on purpose. We will not fill them in for you, and you should be suspicious of anyone who does.
START AT THE UNIT, NOT THE BUSINESS.
A "unit" in this model is one enrolled patient completing one program cycle — not one visit, not one product sale. Metabolic wellness is a program business: the patient enrolls for a defined span of weeks, comes in on a schedule, and consumes a predictable bundle of supplies, clinician time, and staff attention across that span.
Modeling at the visit level hides the real cost, because the expensive visits are front-loaded and the cheap ones are at the back. Modeling at the whole-business level hides it too, because you can't tell whether a weak month is a pricing problem or a volume problem. The cycle is the unit that answers both.
So define your unit precisely before you calculate anything:
- Cycle length — ___ weeks.
- Clinical touchpoints per cycle — ___ visits, of which ___ are with a licensed clinician and ___ are with support staff.
- Program price per cycle — $___ , and whether it is collected up front, monthly, or financed.
- Expected completion rate — ___ percent of enrollees finish the cycle. This one is uncomfortable and most models omit it. Don't.
THE COST STACK: SIX INPUTS.
Direct cost per cycle is the sum of six things. Get quotes for all six — real quotes, in writing, in your market — before you build any spreadsheet.
1. PRODUCT AND SUPPLY COST.
Whatever the program dispenses or administers across the cycle, at your actual landed cost including shipping, cold-chain handling if applicable, and waste. Model waste explicitly at ___ percent; single-use and short-dated items generate more of it than people expect. Note whether your supply cost is per patient or per unit purchased, because minimum order quantities turn a variable cost into a partly fixed one.
2. CLINICIAN TIME.
The binding constraint in almost every clinical services model. Price it as a fully loaded hourly figure — salary or contract rate plus payroll taxes, benefits, and malpractice allocation — then multiply by clinician minutes actually consumed per cycle. Include the minutes that don't happen in the room: chart review, orders, refills, messages, and oversight of anything delegated. If your state's scope rules require physician or NP involvement at defined points, those minutes are not optional and must appear in the model.
3. LAB AND SCAN.
Per-cycle cost of any baseline and follow-up panels, plus any body-composition or metabolic assessment the program includes. Two variables matter: your negotiated per-panel price at ___ dollars, and how many times per cycle it repeats. If a scan device is owned rather than billed per use, it belongs in fixed cost and depreciation, not here — and its per-scan cost then depends entirely on volume, which is the whole point of the capacity section below.
4. STAFF HOURS.
Intake, scheduling, insurance-free billing, follow-up calls, retention outreach, and room turnover. Fully loaded hourly rate times minutes per cycle. Support staff time is the single most under-counted line in home-built models, because it is diffuse and nobody logs it.
5. RENT AND FACILITY ALLOCATION.
Rent is a fixed cost, so it does not belong in per-unit direct cost — but you still need it allocated per room-hour to do capacity math. Take total monthly occupancy cost (base rent, CAM, utilities, insurance) divided by usable clinical room-hours available per month. That gives you a room-hour rate of $___ , which is the number you will use to compare one program against another for the same square footage.
6. MERCHANT AND FINANCING FEES.
Cash-pay means card-pay. Assume ___ percent plus a per-transaction fee on every dollar collected, higher if you accept patient financing, where discount rates on the funded amount are materially larger than card processing. Model it against gross collections, not net — and remember refunds and chargebacks cost you the fee twice.
CAPACITY MATH: ROOMS × HOURS × UTILIZATION.
Cost tells you what one cycle consumes. Capacity tells you how many cycles the physical business can hold. Every ceiling in a services business is a capacity ceiling, and there are only three levers.
The arithmetic:
- Rooms (___) × open hours per week (___) = gross room-hours per week.
- Gross room-hours × realistic utilization (___ percent) = productive room-hours.
- Productive room-hours ÷ room-hours consumed per patient cycle (___) = cycle capacity per week.
Three disciplines make this honest. First, utilization is never 100 percent and rarely close — no-shows, turnover time, lunch, and uneven demand across the day all subtract. Pick a number you can defend to a lender. Second, run the same calculation for your clinician hours, because a clinic can be room-limited or clinician-limited and the fix is completely different. Whichever produces the smaller number is your real ceiling. Third, apply your completion-rate assumption; enrollments and completed cycles are not the same quantity.
GROSS MARGIN VS. CONTRIBUTION MARGIN.
These get used interchangeably, and the difference is where most home-built models go wrong.
Gross margin is program price minus the cost of goods — product, supplies, labs. It is a useful sanity check on pricing and supply negotiation, and it is flattering, because it excludes the labor that actually delivers the service.
Contribution margin is program price minus all variable costs of serving that patient: goods plus clinician minutes, staff minutes, and merchant fees. It answers the only question that matters at the unit level — does one more enrolled patient leave anything behind after the cost of serving them?
Contribution margin is what covers fixed cost. Rent, software, insurance, base salaries, and marketing overhead do not care how many patients you saw; they are paid from the pool of contribution dollars. So the structural relationship is:
- Contribution per cycle = price − (product + labs + clinician minutes + staff minutes + merchant fee).
- Cycles required to cover fixed cost = total monthly fixed cost ÷ contribution per cycle.
- Compare that required number against your capacity ceiling from the section above. If the required number sits close to the ceiling, the model has no slack — and slack, not upside, is what carries a business through a slow quarter.
Two more mechanics worth modeling once you have the base: retention, since a second cycle from an existing patient carries no acquisition cost and often fewer intake minutes, and acquisition cost, which is marketing spend divided by new enrollments and belongs in your decision even though it sits outside contribution margin.
HOW THIS APPLIES TO A LICENSE.
Run the model twice: once with a percentage of gross revenue subtracted, once without. In many national chain structures, an ongoing royalty of roughly 6–10 percent is charged on gross revenue, not profit — which means it is deducted before your cost stack, in strong months and weak ones alike, and it raises the number of cycles required to cover fixed cost. An Atlas license charges zero ongoing royalty: the cost is front-loaded and finite, and it appears in your model as a capitalized entry cost rather than a permanent line against revenue.
That is a structural statement about where cost sits, not a claim about what any business will earn. The mechanics of the percentage are covered in What a Royalty Really Costs, and the structural comparison in Franchise vs. License.
BUILD YOUR OWN NUMBERS.
Take the six cost inputs and the three capacity levers, get real quotes in your own market, and build the model yourself — or with your accountant, which is better. Then bring it to us and we'll pressure-test the assumptions against what a buildout actually requires, including the ones that make the model look worse. Start an application, or book a fit call and bring your spreadsheet. We will not hand you a revenue number, on that call or ever — and "not a fit" remains a real possible answer in both directions.
