The short answer
Adjusted EBITDA is a med spa’s earnings before interest, tax, depreciation and amortisation, restated to remove costs that exist only because the current owner runs the practice. Buyers apply the multiple to this figure rather than to reported profit, which means every accepted adjustment is multiplied — and every rejected one is subtracted at the worst possible moment.
Quick answers
Six narrow questions, one sentence each. These catch conversational queries that don’t warrant reading the article. Phrased deliberately differently from the FAQ at the bottom, and not included in the FAQPage schema.
What is an add-back? A cost removed from reported earnings because a new owner would not incur it — an owner’s personal expense, a one-time cost, or compensation above market rate.
Do add-backs always increase the number? No — an owner paying themselves below market rate produces a downward adjustment, and it is not negotiable.
How much can add-backs move a valuation? By whatever the adjustment is, multiplied by the multiple, which is why a modest documentation failure becomes a large number.
Who decides which add-backs count? The buyer’s quality of earnings reviewer, testing each one individually against evidence rather than against explanation.
When should I start documenting them? Two years before a sale, contemporaneously — reconstruction during diligence is possible, slow, and rarely persuasive.
Is adjusted EBITDA the same as seller discretionary earnings? No — SDE adds back the owner’s entire compensation, adjusted EBITDA does not, and the two produce different multiples for an identical practice.
Key takeaways
- The multiple is applied to adjusted EBITDA, so every dollar of accepted add-back is worth several dollars of enterprise value — and every dollar rejected costs the same.
- Add-backs fail in diligence for lack of documentation far more often than for lack of merit.
- An owner who also injects generates two separate adjustments, and owners routinely account for only one of them.
- Adjustments run in both directions; below-market owner compensation and below-market related-party rent both reduce the figure.
- A padded schedule damages credibility across the whole transaction, including the entries that were legitimate.
Why adjusted EBITDA is the number that gets multiplied
A buyer is not purchasing your reported profit. They are purchasing an estimate of what the practice will earn under their ownership, which is a different figure and usually a larger one.
Reported profit includes costs that exist because you own the practice — your compensation above what a replacement would cost, the vehicle, the family member on payroll, the legal dispute that happened once. None of those continue for a new owner, so none of them belong in the number that gets multiplied.
Adjusted EBITDA is that restatement. It is also sometimes called normalised or pro-forma EBITDA; the terms are used interchangeably and mean the same thing.
The arithmetic that makes this worth two years of attention
The multiple compounds every adjustment.
At a 5× multiple, $120,000 of accepted add-backs is $600,000 of enterprise value. The same $120,000, rejected in a quality of earnings review because there was no invoice behind it, is $600,000 that leaves the offer.
Sofer Advisors, reviewing 2026 med spa transactions, notes that proper identification of owner add-backs, one-time expenses and above-market owner compensation commonly moves adjusted EBITDA by $50,000 to $200,000 in a mid-sized practice.
At mid-market multiples that range represents a meaningful share of the price, and it is decided almost entirely by record-keeping rather than by negotiation.
And the timing that makes it worse
Rejected add-backs do not surface early. They surface during confirmatory diligence — after the letter of intent, inside exclusivity, when the competitive process that gave you leverage has been switched off by agreement.
That is the moment a buyer discovers the schedule cannot be supported, and it is the moment you have the least room to argue about it.
What is an add-back?
An add-back is a cost removed from reported earnings on the basis that a new owner would not incur it. There are three legitimate categories: costs that are owner-specific, costs that are genuinely non-recurring, and costs recorded at something other than market rate.
Everything defensible falls into one of those three. Anything that does not is a negotiation you will lose.
Which add-backs do buyers usually accept?
Buyers accept adjustments that are documented, genuinely owner-specific or non-recurring, and supportable without explanation. The list below covers what appears most often in medical aesthetics.
Owner compensation above market
If you pay yourself $400,000 and an employed replacement would cost $220,000, the difference is added back.
Establishing what “market” means is the negotiation. Buyers reference employed-provider compensation in your region and at your volume, not your view of what you are worth.
Personal expenses run through the practice
Vehicle and travel, phone, family members on payroll who do not work in the business, conference attendance beyond what the practice requires, personal treatments taken by the owner or their family.
That last one is specific to this sector and it appears in nearly every med spa schedule. It is legitimate — the product and chair time were consumed, and a new owner would not consume them — but it needs to be quantified from treatment records rather than estimated.
One-time and non-recurring costs
A build-out. A legal dispute. A software or EMR migration. The launch campaign for a second location. Recruitment fees for a provider who is now in place.
The test is whether the cost recurs, not whether it felt exceptional.
Costs of a discontinued service line
A device modality you no longer offer, a treatment category you exited, the residual costs of a partnership that ended. Where the line is genuinely closed and the costs genuinely stopped, the adjustment holds.
Related-party rent above market
Where you own the building through a separate entity and charge the practice above market rent, the excess is added back.
Note that this one is symmetrical, which brings us to the section owners like least.
The add-backs that run against you
Not every adjustment increases the number. Three run the other way, and buyers apply them whether or not the seller raises them.
Owner compensation below market
If you have been paying yourself little and reinvesting, a buyer subtracts a market salary — because they will have to employ somebody to do what you have been doing for free.
This surprises owners consistently, and it is not negotiable. The practice’s earnings have been flattered by unpaid labour, and the correction is arithmetic rather than opinion.
Related-party rent below market
Same mechanism, opposite direction. Below-market rent between related parties inflates earnings, and it is normalised to market during diligence.
A management layer that does not exist
If nobody in the practice performs the operations, HR and finance functions that a business of your size requires, because you absorb them alongside treating patients, a buyer adds the cost of a manager.
The two-adjustment problem, and why owner-injectors get it wrong
This one is specific to medical aesthetics and it produces more disappointment than any other item on the schedule.
An owner who also injects performs two distinct roles: they run the business, and they generate treatment revenue.
Replacing you therefore requires two hires, or one hire and a revenue consequence. Owners routinely add back their entire compensation as though a single manager replaces them, and buyers routinely model it correctly — which is where the two figures diverge, usually late.
How a buyer actually models it
The management role is replaced by an employed manager at market cost. Straightforward.
The production role is replaced by an employed injector, and an employed injector is paid out of the revenue they generate. That compensation is a cost of delivering the service, not an add-back. A practice where the owner personally delivers, say, half of injectable revenue does not simply gain that revenue at full margin under new ownership — it gains the revenue and inherits the provider cost.
What that means for the schedule
Add back the management component of your compensation. Treat the production component as a cost that transfers with the role.
It is a smaller number than owners expect, and presenting it correctly is worth more than presenting the larger one and defending it unsuccessfully. A buyer who sees a schedule that already models this properly reads the rest of the file differently.
This is also, incidentally, the arithmetic behind owner dependency — the largest single discount in the sector. We cover that in what a med spa is worth.
Which add-backs do buyers reject?
Buyers reject adjustments that cannot be evidenced, that describe events which did not occur, or that relabel recurring costs as exceptional. Four patterns account for most rejections.
“Lost revenue.” Revenue from an event that did not happen — a closure, a provider departure, a slow quarter — is not an earnings adjustment. Buyers will not pay for a hypothetical.
Recurring costs relabelled as one-time. Marketing spend described as a launch campaign in three consecutive years is marketing spend. Buyers compare the schedule to the general ledger across the full period.
Anything without an invoice, a bank record, or a contract. This is the single largest cause of rejection, and it has nothing to do with the merit of the underlying claim.
Adjustments that appeared for the first time in the sale schedule. A cost identified as personal only once a buyer was involved invites the question of what else was reclassified, which is a more expensive conversation than the item itself.
How to document add-backs so they survive
The instruction is short and the discipline is not: document contemporaneously, not retrospectively.
For each adjustment you intend to claim, hold:
- The invoice or contract
- The bank or card record showing payment
- A one-line note recording why it is owner-specific or non-recurring, written at the time
- Where relevant, the comparison evidence — market compensation data, a market rent assessment
Then maintain a running schedule rather than assembling one under deadline. A schedule that has existed for two years reads entirely differently from one produced in a fortnight, and reviewers can tell the difference immediately.
The credibility multiplier
One point worth stating plainly, because it governs everything above.
A schedule padded with optimistic entries does not merely lose those entries. It causes every other figure in the file to be re-examined — including the ones that were correct. The cost of an unsupportable add-back is frequently larger than the add-back.
Present the entries you can support. Disclose the ones that need explanation before they are discovered. Both are faster and both price better.
What happens to your schedule in a quality of earnings review
A quality of earnings review is an independent accounting analysis the buyer commissions to test whether the earnings you have presented are real, recurring, and correctly stated. It is not an audit — it is targeted, and add-backs are one of its principal targets. It is standard above roughly $1 million of adjusted EBITDA.
Expect each adjustment to be examined individually, against evidence rather than against explanation. Expect revenue tested against bank deposits, related-party arrangements examined specifically, and package and membership revenue recognition tested against delivery rather than collection.
That last item is not strictly an add-back question, but it lands on the same schedule and it catches med spa sellers regularly. Package revenue collected in advance represents an obligation to deliver treatment later, and a reviewer will restate it accordingly.
Adjusted EBITDA or SDE — a note on which applies
Briefly, because it belongs to the pillar rather than to this page.
Seller discretionary earnings adds back the owner’s entire compensation and is the right basis where the owner is the practice’s principal producer. Adjusted EBITDA does not, and assumes those roles are filled by employed people at market rates.
A 3× SDE multiple and a 5× adjusted EBITDA multiple can describe an identical price for an identical practice. When a buyer quotes a multiple, establish which basis it refers to before comparing anything.
The full explanation, with the ranges by size band, is in what a med spa is worth.
Frequently asked questions
What is adjusted EBITDA for a med spa? Earnings before interest, tax, depreciation and amortisation, restated to remove costs that exist only because the current owner runs the practice — above-market owner compensation, personal expenses, one-time items, and rent recorded away from market. Buyers apply the multiple to this figure rather than to reported profit.
What are the most common med spa add-backs? Owner compensation above market, personal expenses run through the practice, one-time legal or professional fees, launch campaigns for a new location, costs of a discontinued service line, and above-market related-party rent.
Can an add-back reduce my valuation? Yes. Below-market owner compensation, below-market related-party rent, and the absence of a management layer all produce downward adjustments, and buyers apply them whether or not the seller raises them.
Why do add-backs get rejected? Most often for lack of documentation rather than lack of merit. Buyers also reject claimed revenue from events that did not occur, recurring costs relabelled as one-time, and adjustments that appeared for the first time in the sale schedule.
How far in advance should I document add-backs? Two years, contemporaneously. Retrospective reconstruction during diligence is possible, slow, and rarely persuasive — and it happens at the point in the process where you have least leverage.
Does a quality of earnings review examine every add-back? Individually, yes, against evidence rather than explanation. A quality of earnings review is standard above roughly $1 million of adjusted EBITDA and is where unsupportable adjustments are removed.
