What Is EBITDA for a Dental Practice?

EBITDA is a profitability metric that strips out financing decisions, tax strategy, and non-cash accounting to show what a business actually earns from its operations. For dental practices, it appears most often in acquisition conversations — buyers and DSOs use it to compare practices and set purchase prices. This FAQ explains what it means, how it's calculated for a dental-specific context, where it differs from collections-based valuation, and what owners can do to move the number before a sale.

What Does EBITDA Actually Stand For?

EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. The point is to isolate operating earnings by removing variables that differ across owners, capital structures, and tax situations.

Interest and taxes reflect how a practice is financed and how its owner manages their tax position — neither tells a buyer much about the business itself. Depreciation and amortization are non-cash charges that reduce reported income without touching cash flow. Removing all four gives a cleaner number to compare across practices.

How Is EBITDA Calculated for a Dental Practice?

The formula is straightforward: start with net income, then add back interest expense, tax expense, depreciation, and amortization.

EBITDA = Net Income + Interest + Taxes + Depreciation + Amortization

In practice, the calculation for a dental practice usually includes one additional step: add-backs. These are owner-specific expenses that reduce reported income but wouldn't transfer to a new owner — the doctor's salary above fair market compensation, personal vehicle expenses run through the practice, owner health insurance, and similar items. Buyers expect these. A properly restated EBITDA is sometimes called adjusted EBITDA or seller's discretionary earnings (SDE), depending on the deal size and who's doing the analysis.

Getting this number right matters. Overstated add-backs will surface in due diligence and erode buyer confidence. Understated add-backs leave money on the table.

Why Don't Dental Practice Buyers Just Use Collections?

They often do — collections-based multiples remain common in smaller general practice transactions, and many practice brokers quote valuations as a percentage of gross collections. But collections tell you revenue. EBITDA tells you what's left after running the practice.

Two practices collecting $1.2 million annually can look identical on a collections-based valuation and be vastly different investments. One might carry a 35 percent overhead ratio. The other might be at 65 percent. EBITDA surfaces that gap immediately.

DSOs and private equity-backed buyers almost universally underwrite on EBITDA multiples because they're comparing dozens of practices with different fee schedules, insurance mixes, and overhead structures. A collections multiple obscures those differences. An EBITDA multiple cuts through them.

What Is a Typical EBITDA Multiple for a Dental Practice?

Multiples vary significantly by practice size, geography, specialty, growth trajectory, and buyer type. DSO acquisitions have historically commanded higher multiples than private-party sales — a solo general practice selling to another dentist may transact at a different range than a multi-location group attracting PE-backed interest.

No single "market multiple" applies universally, and any figure you read online reflects a moment in time and a specific buyer segment. A qualified dental practice broker or CPA with transaction experience can give you a current, deal-specific range. The American Dental Association and the Academy of Dental CPAs are reasonable starting points for finding advisors familiar with dental-specific deal structures.

How Does EBITDA Relate to the Practice's Profit and Loss Statement?

Your P&L is the starting point, but it rarely hands you a clean EBITDA number directly. Most dental practice P&Ls are prepared for tax purposes — which means they're optimized to minimize taxable income, not to present the practice in the best light for a sale.

Owner compensation often needs to be recast to fair market value for a dentist of that specialty and region. Expenses that are personal in nature but run through the business need to be identified and added back. One-time costs — a major equipment repair, a lease dispute, a litigation settlement — may warrant normalization if they don't represent ongoing operations.

The result is a recast profit and loss statement, sometimes called a normalized P&L. That document, not the tax return, is what a sophisticated buyer's advisor will analyze.

What Drags Down EBITDA for a Dental Practice?

High overhead is the most common culprit. Labor costs, supply costs, and occupancy costs that are out of line with production will compress EBITDA regardless of collections volume.

A few other patterns appear repeatedly:

Overhead categories that commonly suppress EBITDA:

• Staff wages and benefits above the benchmark for practice size and specialty

• Lab fees that haven't been renegotiated as production has grown

• Supply costs with no purchasing discipline or vendor comparison

• Rent set years ago that now exceeds market rate — or below-market rent that a buyer knows won't last

• Discretionary owner spending coded to business expense categories

Owner-dependency also matters, even though it doesn't appear as a line item. A practice where all production runs through the owner and no associate capacity exists is a riskier asset — buyers often price that risk into the multiple, which has the same effect as a lower EBITDA.

What Can a Practice Owner Do to Improve EBITDA Before a Sale?

The most impactful moves tend to be operational rather than financial. Margin improvements that are real and sustainable will hold up in due diligence. Cosmetic adjustments generally won't.

Start with overhead benchmarking. If your staff costs or supply costs are running above industry norms, buyers will notice. Tightening those categories two to three years before a sale lets the improvement show up in a multi-year earnings history, which is how buyers typically assess trend.

Next, look at collections efficiency. Unpaid balances and slow insurance reimbursements reduce net income directly. A dental collections ratio below benchmark signals billing problems to buyers — and billing problems suggest revenue the practice isn't capturing.

Production-per-hour and provider scheduling data matter here too. Buyers want to see capacity utilization. Practices that can demonstrate consistent production against available chair time are easier to underwrite. Dental practice reporting that surfaces those metrics regularly gives you the documentation to support your adjusted EBITDA.

Finally, reduce owner-dependency where you can. Adding an associate, building out hygiene production, or demonstrating a patient base that returns regardless of which provider they see all improve the quality of earnings — not just the amount.

Does Practice Management Software Affect EBITDA?

Indirectly, yes. Software doesn't appear as a line item that moves EBITDA on its own. But the systems a practice runs on affect the operational efficiency that EBITDA measures.

Practices with disconnected systems — separate billing platforms, manual insurance verification, paper-based records — carry hidden labor costs that show up in overhead ratios. Those practices also tend to have gaps in reporting that make it harder to reconstruct a clean earnings history for a buyer.

Curve Dental is a cloud-based dental practice management platform built to consolidate those functions. Owners who can pull clean production, collections, and overhead data from a single system spend less time preparing for due diligence and are better positioned to support their numbers.

Where Should a Dental Practice Owner Start If They're Thinking About a Sale?

Start with your numbers, at least two to three years out. Engage a CPA who works specifically with dental practices — general business CPAs often miss the dental-specific add-backs and recast conventions that affect valuation. The Academy of Dental CPAs maintains a directory of member firms.

Get a practice valuation done before you're in a hurry to sell. Understanding your current EBITDA and the multiple a buyer would likely apply gives you time to act on the levers that move both.

The practices that sell well are usually the ones that ran well. EBITDA is the clearest signal of that.
