EBITDA Add-Backs: How Owner Expenses Get Normalized Before a Sale

EBITDA add-backs are where a lot of the real negotiation in a practice sale happens — not in the multiple itself, but in what counts as a legitimate adjustment to the earnings figure the multiple gets applied to.

The basic idea

EBITDA add-backs normalize a practice's earnings by removing expenses that are specific to the current owner and wouldn't continue under new ownership. The goal is to show what the practice would earn as a standalone, professionally run business, separate from decisions the current owner made for personal or tax reasons.

The most common add-back categories

Owner compensation above market rate is usually the largest single add-back — if the owner-veterinarian's salary exceeds what hiring a replacement associate doctor would cost for the same clinical output, that difference gets added back to earnings. Personal expenses run through the practice (a vehicle, family health insurance, travel not tied to a conference or genuine business purpose) are common and generally straightforward once documented. Above-market rent paid to a related real-estate entity the owner also controls is another frequent one, adjusted down to a fair-market rate for comparable space. One-time expenses — a lawsuit settlement, a major one-off equipment repair — can also qualify if genuinely non-recurring.

A worked example

A practice shows $180,000 in reported EBITDA. The owner's salary is $220,000 against a $150,000 replacement-associate cost ($70,000 add-back). A personal vehicle lease runs $12,000 a year through the practice. Rent to a related entity runs $8,000 above comparable market rate. Adjusted EBITDA: $180,000 + $70,000 + $12,000 + $8,000 = $270,000 — a 50% increase over the reported figure, which is a meaningfully different starting point once a valuation multiple gets applied.

Why documentation matters more than the adjustment itself

Buyers scrutinize every proposed add-back, and an undocumented one is far more likely to get rejected or discounted during negotiation than a well-documented one, regardless of whether the underlying claim is legitimate. A seller who can point to a specific line item, a comparable market-rate rent quote, or a clear separation between business and personal use of a vehicle is in a much stronger negotiating position than one asserting the adjustment without backup.

Starting the process early

Practices planning a sale in the next few years benefit from starting to separate and document owner-related expenses well before a buyer conversation begins — not to change how the practice is run day to day, but so the eventual add-back list is already substantiated rather than reconstructed under deal pressure.
