SDE vs. EBITDA in Veterinary Practice Valuation

SDE and EBITDA both start with the practice’s financial statements. They answer different buyer questions.

• SDE asks: What total financial benefit could one owner-operator receive from this business?
• Adjusted EBITDA asks: What operating earnings remain after paying the people required to run the practice, including a replacement for the selling owner’s work?

This article answers the veterinary-specific SDE-versus-EBITDA question. For the broader valuation process, see How to Value a Veterinary Practice; for the adjustments that feed the calculation, see Veterinary Practice Valuation Add-Backs.

Using the wrong measure can change an estimated value by millions of dollars because SDE is usually larger while the multiple applied to it is usually lower.

Side-by-side definition

	SDE	Adjusted EBITDA
Full name	Seller’s discretionary earnings	Adjusted earnings before interest, taxes, depreciation, and amortization
Best fit	Smaller owner-operated practice; individual buyer	Larger or management-capable practice; corporate or strategic buyer
Owner compensation	Usually added back for one owner-operator	Replaced with market-rate clinical and management cost
Personal/discretionary costs	Added back if documented and nonessential to buyer	Added back if documented and nonessential to buyer
Nonrecurring items	Adjusted when truly nonrecurring	Adjusted when truly nonrecurring
Typical buyer question	“What can I earn if I replace the seller?”	“What earnings remain if the seller is replaced?”

BizBuySell, a large small-business marketplace, defines SDE as the full economic benefit generated for an owner-operator and distinguishes it from EBITDA used by larger or professionally managed businesses (BizBuySell SDE guide). Veterinary transactions add an important complication: an owner may be doing clinical work, management work, or both.

Why owner labor must be visible

The AVMA’s 2024 Veterinary Practice Owners Survey found that owners spent more than 65% of their time with clients and patients, plus roughly 18.6% to 23.3% managing operations depending on practice type (AVMA 2025 report, p. 47).

That means an owner’s paycheck may compensate several different economic roles:

1. Producing veterinarian;
2. Medical director or lead clinician;
3. Practice manager or executive; and
4. Investor receiving a return on ownership.

A buyer cannot determine sustainable earnings until those roles are separated.

A worked veterinary example

Assume a companion-animal practice reports the following annual figures:

Item	Amount
Pretax profit after owner compensation	$250,000
Owner salary and benefits	$180,000
Interest	$20,000
Depreciation and amortization	$30,000
Documented personal vehicle expense	$10,000
Documented one-time legal expense	$15,000
Supported market replacement compensation	$150,000

Illustrative SDE

Start with pretax profit and add back one owner’s compensation, interest, depreciation and amortization, personal vehicle expense, and the one-time legal expense:

$250,000 + $180,000 + $20,000 + $30,000 + $10,000 + $15,000 = $505,000 SDE

This asks what one owner-operator might receive if that person steps into the seller’s work.

Illustrative adjusted EBITDA

Start with pretax profit, add back interest, depreciation and amortization, and the accepted discretionary/nonrecurring items. Then replace the owner’s $180,000 compensation with the supported $150,000 market cost, producing a $30,000 adjustment:

$250,000 + $20,000 + $30,000 + $10,000 + $15,000 + $30,000 = $355,000 adjusted EBITDA

This asks what earnings remain after the buyer pays someone to replace the owner’s labor.

The $150,000 replacement cost is illustrative. A real analysis should consider geography, species focus, experience, schedule, production, benefits, recruiting conditions, and management duties. As a broad reference point—not a valuation input by itself—the Bureau of Labor Statistics reported a May 2024 median annual wage of $125,510 for veterinarians and explicitly notes that pay varies by responsibility and geography (BLS: Veterinarians).

The mistake that overstates value

Suppose someone applies a corporate 10x multiple to the $505,000 SDE. The result is $5.05 million. Applying the same illustrative multiple to the $355,000 adjusted EBITDA produces $3.55 million.

The $1.5 million difference is not a sophisticated disagreement about the market. It is largely the cost of replacing the owner’s work.

This does not mean SDE is wrong. If another veterinarian plans to buy the practice and personally perform the seller’s clinical and management roles, SDE may be the more relevant way to evaluate owner economics. But that buyer will usually use a different multiple and must still test whether the resulting debt and compensation are supportable.

How to choose the right measure

Use SDE as a primary lens when:

• The practice is built around one owner-operator;
• The likely buyer is another veterinarian who will replace that owner;
• The owner performs most clinical and management work; and
• The buyer is underwriting personal income and debt service.

Use adjusted EBITDA as a primary lens when:

• The practice can operate with a paid clinical and management team;
• Several DVMs contribute production;
• The likely buyer is a group, consolidator, or investor; and
• Owner labor can be replaced at a supportable market cost.

Use both when more than one buyer path is plausible. That is often more informative than forcing one practice into one category too early.

Questions to ask about any SDE or EBITDA figure

• What exact starting line on the financial statements was used?
• Which owner’s compensation was added back?
• What replacement clinical and management costs were included?
• Are benefits and payroll taxes included in replacement cost?
• Which expenses are personal, nonrecurring, or related-party?
• Are any proposed savings not yet achieved being treated as if they already exist?
• Does the calculation reconcile to tax returns and the general ledger?
• Is the multiple based on the same earnings definition?

AAHA’s operating-profit guidance emphasizes that owner payments, related-party rent, family compensation, and personal expenses may need adjustment—and that EBITDA without those adjustments is not meaningful (AAHA: Profit Checkup).

The practical answer depends on the buyer

SDE and adjusted EBITDA are not competing versions of the truth. They describe the practice from different buyer perspectives.

For an individual veterinarian, the relevant question may be, “What can this business provide if I do the seller’s work?” For a corporate buyer, it may be, “What remains after we pay market rates to replace the seller?” A transparent valuation should show which question it answers.
