Pricing by Chair Time in Facial Harmonization

Almost every price list in facial harmonization (HOF in Brazil) starts from ml: so much per ml of filler, so much per area. It is an easy language to understand and to compare. But it hides a problem: in procedures with little material and a lot of time, the ml does not pay for the work. Anyone who prices only by ml ends up selling precision procedures cheaply and volume procedures dearly, without noticing.

This guide presents pricing by chair time: calculating a minimum price from appointment minutes, adding materials, and using the difference to adjust your price list. The goal is not to replace the per-ml price, but to have a floor that protects your margin. The numbers are hypothetical, and clinical decisions must never be guided by time or price.

What chair time is

Chair time is the interval during which the practitioner and the room are dedicated to the patient: not only the application, but also the welcome, medical history, preparation, photos, anesthesia, procedure, aftercare instructions and record keeping. In many clinics, this time is longer than the practitioner imagines. Measuring it for two weeks with a simple stopwatch is usually revealing.

Step 1: calculate the clinical hour cost

Add up the clinic's monthly fixed costs (rent, permanent staff, software, accounting, utilities, your own pay) and divide by the month's productive hours, the ones with a patient in the chair. See clinical hour cost in HOF and the glossary entry clinical hour.

Hypothetical example: fixed costs and your pay add up to R$ 36,000.00 per month, and the schedule has 90 productive hours. The hour costs R$ 400.00. If occupancy improves to 110 hours, it drops to about R$ 327.27. That is why idle capacity matters: empty hours make occupied hours more expensive.

Step 2: multiply by the real time

Use the average time you measured, not the time you wish for. For a procedure with 75 minutes of chair time:

Time cost = 1.25 h × R$ 400.00 = R$ 500.00.

That is the time floor: before adding a single cent of material, the procedure already needs to bring in R$ 500.00 to cover the share of overhead and practitioner time it consumed.

Step 3: add materials and the rest

With fees and taxes of 14% and a net margin of 30%, price = R$ 1,058.33 ÷ 0.56, about R$ 1,889.88.

Step 4: compare with the per-ml price

Now comes the reveal. Suppose the procedure uses 1 ml and the clinic's price list charges R$ 1,200.00 per ml (hypothetical). The per-ml price is below the required minimum of R$ 1,889.88. The procedure is long and uses little material: by ml it looks small; by time it is heavy.

In A, the price list price (4 × R$ 1,200.00 = R$ 4,800.00) is well above the floor: there is margin to spare. In B, the price list falls short: a hidden loss. In C, the price list covers it comfortably. The clinic may be subsidizing B with the profit from A without realizing it.

Combining time and materials: the procedure fee

One way to organize this is to split the price into two parts:

1. Procedure fee: covers time, overhead, follow-up and margin.
2. Material fee: covers the product, including waste.

Price = procedure fee + (ml × material price per ml). This structure is common in health services and has an advantage: it shows the patient what they are paying for. The downside is that it requires explanation, and comparison with competitors becomes harder, which is not a problem but a consequence of having a price that reflects your cost.

See pricing by ml for the traditional logic and how to build the clinic's price list for the full structure.

The ethical limit of time

Time-based pricing carries a risk: using time to justify more procedures, more sessions or more volume. Never:

• Stretch the appointment to justify the price.
• Suggest more areas because the chair is "idle".
• Change the indication to fill an empty schedule.

Time is a tool for cost calculation, not for indication. The assessment defines what to do, the expected time follows from what was indicated, and the price follows from the calculation.

If the clinic uses Harmy

The app helps reduce wasted consultation time and keeps the plan clear. With the front-facing photo, the markings and the ml per area, the Before/After slider shows the illustrative simulation, and presentation mode lets the patient see only the slider. The PDF quote uses the per-ml price per area saved in My clinic; if you adopted a procedure fee, use the notes field to describe what is included and the discount field consistently with your policy.

Measuring occupancy to refine the calculation

The clinical hour is only accurate if occupancy is measured. If the schedule has many gaps, the occupied hour pays for the empty hour. See schedule occupancy rate in HOF and revenue per clinical hour in HOF. If occupancy rises, the hour cost falls and the floor for each procedure drops. If occupancy falls, the opposite happens.

Questions for reviewing the floor

Common mistakes

Using available hours instead of productive hours. This underestimates the cost.

Forgetting cleaning and preparation time between patients. It occupies the room and belongs in the calculation.

Calculating the floor and thinking it is the price. The floor is the minimum; the price takes the market, positioning and perceived value into account.

Not reviewing. Rent, staff and taxes change, and the clinical hour follows. See annual price adjustment in HOF.
