EBITDA for Dental Practices: What It Is and Why It Matters

If you have ever been told your practice runs at 35% EBITDA, you were almost certainly told the wrong thing. Not because the arithmetic was wrong, but because the label was. That number is usually SDE, and the difference between the two is your own clinical income. It is the single largest line in the calculation, and confusing the two is how an owner arrives at a valuation conversation carrying a figure a buyer will cut roughly in half before the first meeting ends.

This post is about what EBITDA actually measures in a dental practice, why the adjustment matters more here than in almost any other small business, and what the number is used for. It is not a valuation. It is the vocabulary you need before a valuation is worth having.

What EBITDA means in a practice you also work in

EBITDA is earnings before interest, taxes, depreciation and amortization. The idea is to strip out the things that reflect how a business was financed and how its assets were bought, so two businesses can be compared on the operations themselves. Interest depends on your loan. Depreciation depends on when you bought the chairs. Neither tells a buyer how well the practice runs.

In most small businesses that is the whole story. In a dental practice it is not, because of one structural fact: the owner is also the largest producer. A practice's profit and loss statement shows what is left after the owner has been paid whatever the owner decided to be paid, and that decision is usually driven by tax planning, not economics. Two identical practices can show profit figures that differ by $200,000 purely because one owner runs a larger salary through payroll than the other.

So a raw EBITDA figure from a dental P&L is meaningless on its own. It measures the owner's compensation election, not the practice.

Why the number is adjusted, and what the adjustment is

The fix is to normalize. You take the owner out of the equation entirely and put a replacement in, at what a replacement would actually cost.

EBITDA = net income, plus interest, taxes, depreciation and amortization

That is the number off your books, and it is where we start. A buyer will not stop there. The term they add is the one most owners have never priced. It is not a bookkeeping entry. It is the answer to a real question: if you walked out tomorrow and the practice had to hire someone to produce what you produce, what would that cost?

Two anchors for it. The Bureau of Labor Statistics puts the median general dentist at $170,950 a year as of May 2025, and that survey specifically excludes the self-employed and owners in unincorporated practices, which makes it a clean read on employed dentists, not a blend. The ADA's own guidance on dentist compensation shows the common contract structures instead: a share of collections, a share of adjusted production, a share of production, or salary plus commission.

Watch the base on those, because it moves the number more than the percentage does. Take one crown at a $1,500 full fee. After a $500 contractual adjustment, adjusted production is $1,000, and at a 98% collection ratio you bank $980. Pay 35% of collections and the associate earns $343. Pay 35% of adjusted production and it is $350. Pay 30% of the full fee and it is $450. Same tooth, same dentist, and the last structure costs you nearly a third more than the first. Anyone quoting you an associate percentage without naming the base has not told you anything yet, and this is exactly the trap that separating associate pay from owner pay in your books is there to prevent.

Expect the two anchors to disagree. The BLS median covers all employed dentists, including part-timers and low producers. A contract percentage scales with what you actually produce, so a high-producing owner costs more to replace than the median dentist earns. Use production when you know it.

Whatever structure you use, it has to be loaded. Payroll taxes, benefits and malpractice ride along with a real hire, and a replacement cost that counts only the wage understates the adjustment every time.

The adjustment runs both ways, and often against you

Owners tend to assume adding owner compensation back is a gain. It is only a gain if you are paid more than your replacement would be.

Take an owner producing $1,000,000 a year. At the 28% to 32% of production associate contracts commonly run, call it 30%, a replacement earns $300,000, and loaded with payroll taxes, benefits and malpractice, call it $360,000. Draw $400,000 against that and the adjustment is worth $40,000. Run a $250,000 salary set for tax reasons against the same $360,000 and the adjustment is negative $110,000. The practice was never earning what the P&L implied. It was borrowing against your own underpayment, and a buyer will find that in the first hour, with the diligence pointed at overhead first.

SDE is not EBITDA, and the difference is your paycheck

Seller's Discretionary Earnings is the same calculation with the owner's own pay and perks left in. It answers "what does this practice put in my pocket," which is a perfectly good question and the right one for an owner-operator deciding whether to buy a practice and work in it.

EBITDA answers a different question: what does this practice earn as a business, once somebody has been paid to do the clinical work. That is what a buyer who is not going to stand at the chair is purchasing.

The two are not interchangeable and they do not carry the same multiple. Quoting an SDE figure as EBITDA inflates the number and then gets it discounted back down, which is a worse outcome than quoting the smaller number correctly in the first place.

The Academy of Dental CPAs publishes no EBITDA benchmark. Its public material carries almost no numeric benchmarks at all, and the ranges that do exist come from the paid NSCHBC and Academy of Dental CPAs benchmark report, which has never contained an EBITDA figure. If you see an EBITDA range attributed to them, the attribution is invented. The same applies to the ADA. Table 17 of the Health Policy Institute's Survey of Dental Practice reports dentist net income and gross billings, and it counts the shareholder-owner's compensation inside practice expenses. That is an owner-income measure, not EBITDA, and it should never be quoted as one.

Three numbers get called EBITDA, and they are not the same size

Work out which one you are holding before you do anything else with it. All three are measured here against net production.

Books EBITDA. Net income plus interest, taxes, depreciation and amortization, straight off the profit and loss, with you paid whatever you chose to be paid. This is the one we report every month, and it is the only one of the three that is a bookkeeping output rather than a negotiating position. It has no useful range, and that is not a gap in the data. It moves with your compensation election, so two practices with identical economics can sit $200,000 apart on it. Its job is to be consistent month to month, not comparable across practices.

Seller's discretionary earnings. The same figure with your own pay and perks left in. Valuation and brokerage sources put it around 35% to 45%. It answers what the practice puts in your pocket, and it is what solo practices usually trade on.

Adjusted EBITDA. Your pay taken out, a market wage for a replacement dentist put in. The same sources put it near 15% to 18% for a solo owner-operator and 18% to 25% or more for a multi-provider practice.

The gap between them is your own clinical income, and it is the largest single line in the calculation. That is why the same practice can be quoted at 40% and at 17% in the same month without anybody lying. The solo and group split has the same cause: in a solo practice you are the production, so a market wage absorbs most of the margin. That is structural, not a failing. Associate production creates margin beyond the owner's own hands, which is the entire financial argument for adding a provider.

Two cautions on the ranges. They are not benchmarks and we do not publish them as scores. Every dental figure of this kind we can find comes from a firm that earns a fee when a practice changes hands: investment banks, brokerages, transition advisers. There is no government dataset, no academic study, and no association figure. Use them to identify which of the three numbers you have been handed, not to grade yourself against it. Where our benchmarks are sourced, they are sourced properly, and our free Dental Practice Benchmark Scorecard checks your practice against the sourced ones in about two minutes.

What the number gets used for

Those two buyers do not price the same way either, which is the part owners are most often surprised by. The group applies a multiple to adjusted EBITDA. The private buyer usually works from a percentage of your annual collections instead, which is a multiple of revenue rather than of earnings, so the same practice can come back with two very different numbers. Neither method is wrong. They are answering different questions, and the gap between the answers is the owner-pay line this whole post is about.

The multiple itself is not fixed, and the clearest pattern across the industry sources is that it scales with size: larger practices and groups command higher multiples than a single small practice, and the same practice is worth a different multiple to a DSO platform than to a neighboring dentist. Multiples also move with the market, so a number you heard a few years ago is not today's number.

The practical consequence is that a dollar of EBITDA is worth several dollars of enterprise value, while a dollar of expense discipline that never reaches EBITDA is worth a dollar. That is the whole reason owners start caring about this number two or three years before they intend to do anything.

What survives diligence

One more thing decides your outcome, and it is not the math. A buyer will only add back what you can document. Add-backs that survive diligence are the ones with paperwork: a one-time legal settlement with the engagement letter and the settlement papers, the documented business portion of a vehicle, a family member's pay above what the role is worth. Add-backs that get rejected are the ones we see most often in practice: a "one-time" expense that shows up in three consecutive years, savings from running short-staffed (a buyer will model a full schedule and load the wage), deferred maintenance, and marketing cuts presented as one-time when new patient counts fell alongside them. Clean books do not just make the calculation possible. They are most of what makes an add-back stand up, and rebuilding that documentation in the middle of a transaction is not realistic.

Two or three years of books that separate owner pay from operating cost is the whole difference between quoting a number and defending one.

P.S. Reciprocity Accounting keeps owner compensation, discretionary spending and true operating cost separated month by month, so the EBITDA conversation starts from a number that is already defensible. See how we can help your practice.

Frequently Asked Questions

What is the difference between EBITDA and adjusted EBITDA?

Plain EBITDA comes straight off the P&L: earnings before interest, taxes, depreciation and amortization, with the owner paid whatever the owner chose. Adjusted EBITDA normalizes that by replacing the owner's compensation with what a replacement dentist would actually cost, and by adding back one-time or personal items that a new owner would not incur. In dentistry the adjusted figure is the one that means anything, because the unadjusted one is mostly a record of a tax decision.

Why does a solo practice show a lower adjusted EBITDA than a group?

Because in a solo practice the owner is the production. Pay a market wage for that clinical work and most of the margin goes with it, which is why a solo practice sits lower on the adjusted figure than a group does, and that is not a warning sign. A group generates profit from associate production on top of the owner's own, so the percentage climbs. Comparing a solo figure to a group figure without adjusting for that is the most common misreading of this number.

My broker quoted 35%. Was that wrong?

Not wrong. Just labeled wrong. 35% to 45% of net production is the normal range for SDE, which leaves your own clinical pay in. If the figure was described as EBITDA, ask directly whether a market-rate clinical wage was deducted for every dentist including you. If the answer is no, it is SDE, and SDE carries a lower multiple than EBITDA. Both numbers are legitimate. Only one of them belongs on each side of that conversation.

Does EBITDA matter if I am never going to sell?

It matters less, but it does not stop mattering. Adjusted EBITDA is the cleanest available answer to whether your practice earns anything beyond paying you to do dentistry. An owner-operator can run a perfectly good career at a low EBITDA and be entirely satisfied. But if you are considering an associate, a second location or a building purchase, that is the number the decision rests on, because those moves are financed out of business earnings, not out of your clinical income.

How far ahead of a sale should I start tracking it?

Two to three years. Buyers look at trailing twelve months and usually want to see the two years behind it, so a practice cleaned up three months before going to market shows a break in the pattern, and a buyer will ask what changed. The other reason is documentation: add-backs need records that exist at the time the expense happened, and those cannot be reconstructed later.

Should EBITDA be measured on production or collections?

We state it against net production, for consistency with every other practice benchmark. Many valuation sources quote it against collections. At a healthy collection ratio of 98% to 100% the ranges hold either way, so the answer rarely changes. What does change the answer is switching bases halfway through a comparison, so pick one and label it every time.
