The Eight Numbers That Run a Med Spa

Med spa KPIs are the operating numbers that show whether a practice converts the demand it already has: revenue per provider hour, rebooking rate, average ticket, consult-to-treatment rate, retail attach, membership churn, cost per new patient and review velocity. Each is decided by its definition before performance ever enters.

The published benchmarks disagree with each other by more than double, because each counts a different population and a different event. What follows is the definition each number needs, the system that holds it, and which published figure, with its provenance, a practice may honestly stand next to.

Why two published average tickets differ by more than double

Two published average tickets for this industry differ by more than double, and neither is wrong. Zenoti's 2026 Beauty and Wellness Benchmark Report, medspa edition, puts the median medspa average ticket at $216. Growth99's 2026 report, published by the American Med Spa Association, puts average visit value at $527. Each counts something different.

Zenoti's figure is aggregated, anonymized 2025 data from North American businesses on its platform, with the 75th percentile at $346 and the top decile at $484, as of October 2026; the pages do not state how many medspa locations sit behind it. Growth99's is a marketing vendor's own survey, published on AmSpa's site in January 2026, with neither sample size nor method stated. One is a platform median, the other a survey average among practices that answered.

Neither can grade a single practice, and a third caveat matters before any Charlotte comparison. AmSpa's own Medical Spa State of the Industry Report page says of the report, as of September 2026: "Report offers national data and does not drill down to individual state or city data." The operating data most likely to be comparable sits behind a paid download, so the comparison that grades a practice is its own trailing twelve months.

The eight numbers, and the definition that decides each one

Each definition has to be settled once and then left alone, because changing it mid-year destroys the only comparison that counts. The table pairs each number with the choice that decides it and the system that holds it. None of these needs software a practice is not already paying for.

The three that say whether an occupied room pays

Revenue per provider hour, average ticket and retail attach say whether an occupied room pays for itself, and the gap they expose is usually utilization rather than price. Zenoti's 2026 report puts medspa staff utilization at 38% at the median against 80% at the 90th percentile, the widest spread of any vertical it measured, as of October 2026.

A spread that wide means the lever is the calendar before the price list. Pick the denominator deliberately: hours the provider was available to be booked is the honest one, because scheduled hours flatter a quiet week and clocked hours punish a provider for admin somebody else assigned them.

Retail attach belongs per provider. A clinic-wide number averages away the only actionable fact in it, which is that one injector mentions aftercare at the end of every appointment and another does not. Dollars per visit is the more useful form, since share of visits treats a cleanser and a full regimen as the same event.

The two that say whether patients come back

Rebooking rate and membership churn decide most of the revenue, because most of it is not a first visit. Growth99's 2026 report, published by AmSpa, puts 73% of med spa revenue as likely coming from repeat patients, so a practice grading itself on new patients alone grades roughly a quarter of its income.

One rebooking is not a rhythm. Zenoti's 2026 report found that among medspa locations where guests were rebooked once, 37% of those appointments were cancelled, while guests rebooked two or more times cancelled at 4%, as of October 2026. A single yes or no cannot see that, so count the second and third return too.

Membership churn hides its largest component in billing rather than in cancellations. A patient who never cancelled but whose card expired in March is churn, and the declined-payment report is rarely anybody's job. Define churn as cancellations plus failed payments unrecovered inside 30 days, and the number stops flattering you.

The three that say whether demand is arriving

Consult-to-treatment rate, cost per new patient and review velocity measure the front of the practice, and two of them have their own guides in this cluster. The definition is the point here: the first needs a denominator chosen and held, the second needs every cost inside it, and the third is a rate, not a total.

On cost per new patient, Growth99's 2026 report, published by AmSpa, puts average new-patient acquisition at $132 against that $527 visit value. Those are the vendor's own survey figures with no method stated. The number that matters is yours, with the agency fee, the software and the staff hours in the denominator rather than the ad budget alone.

Review velocity is governed as well as measured. Under 16 CFR 465.4, as of October 2026, it is a violation to provide compensation or incentives conditioned on a review expressing a particular sentiment, so the ask is uniform to every patient at the same milestone, never gated by how the visit seemed to go. Google's Business Profile guidance says prominence rests partly on how many reviews a business has, which is why the rate beats the lifetime total.

What does this look like when the system runs it?

Med spa owners ask about automated booking systems, and the scoreboard is why that question matters beyond convenience: a booking system that records real availability, the source of each inquiry and the next appointment against the last produces four of the eight numbers above as a by-product, with no reporting project to fund.

That is the half Mirastart builds, and it runs in production for Charlotte businesses today: live-availability booking so every consult is a record rather than an email, an instant automated reply to an inquiry landing at 9pm, reminder and rebooking sequences, a review request fired at one fixed milestone for every patient, and a monthly report whose first line is kept consults. The fee is a flat monthly retainer, from $3,000 a month, never a share of ad spend, and the accounts stay in the practice's name, which is what makes next year's comparison possible at all.
