EBITDA vs. SDE: Which Veterinary Practice Valuation Metric to Use?

When preparing to transition a veterinary clinic, owners will quickly encounter two critical financial acronyms: EBITDA and SDE. While both metrics are used to measure historical profitability and cash flow, they are calculated differently and cater to entirely different types of buyers.

Choosing the wrong metric can result in unrealistic expectations or a mispriced clinic. Below is a breakdown of the differences between EBITDA and SDE, and when you should use each method.

What is Seller’s Discretionary Earnings (SDE)?

SDE represents the total financial benefit an owner derives from operating the business. To calculate SDE, you start with the net profit and "add back" interest, taxes, depreciation, amortization, non-operating expenses, and—crucially—the owner's entire compensation and benefits.

• The Buyer: Private veterinarians (Vet-to-Vet transitions).
• The Logic: An individual buyer needs to know the total cash pool available to pay themselves a living wage and service the business acquisition loan.

What is EBITDA?

EBITDA measures the operating cash flow of the clinic as an independent, standalone entity. Unlike SDE, EBITDA does not include the owner's compensation in the final number. If the owner works as a full-time veterinarian, their salary is treated as a necessary operating expense because a corporate buyer will have to hire and pay an associate veterinarian to do that job.

• The Buyer: Corporate consolidators, private equity, and multi-doctor groups.
• The Logic: Corporate buyers are not buying a job; they are buying an investment return. They need to know what cash remains after paying all necessary staff to run the hospital.

EBITDA vs. SDE Comparison

Feature	EBITDA	SDE
Owner's Salary	Subtracted (treated as a standard operating expense)	Added back to the profit pool
Target Buyer	Corporations and Private Equity	Individual Veterinarians
Multiple Size	Historically Higher	Historically Lower
Best Practice Size	Large, Multi-DVM Hospitals	Smaller, Solo-DVM Clinics

Why Multiples Differ Between the Two

It is common to see corporate EBITDA multiples that appear significantly higher than private SDE multiples. However, this does not automatically mean a corporate sale nets more cash. Because EBITDA subtracts the owner's salary, the baseline number being multiplied is much smaller than the SDE number. It is vital to test different scenarios in our veterinary valuation calculator to see how these math mechanics impact your specific enterprise value.
