How to Value a Dental Practice: A Practical Owner's Guide

Learn how dental practice values are assessed, which earnings measures matter, and how to use a valuation to plan your next move.

If you ask, “What is my dental practice worth?” you will probably hear a percentage of collections first. It is a familiar and useful shortcut. It is not the entire valuation.

A buyer is not purchasing last year’s collections in isolation. The buyer is acquiring the assets, patient relationships, team, systems, location, and future cash flow of a practice—along with the risks required to preserve that cash flow. That is why two practices with identical collections can have very different values.

One may have clean books, stable hygiene and associate production, a transferable lease, modern equipment, consistent profitability, and systems that work without the owner. The other may depend on the selling dentist for nearly every complex case, patient relationship, referral, and management decision. Revenue alone cannot show the difference.

This is the broad dental-practice valuation guide. If you are specifically interpreting market multiples, use Dental Practice Valuation Multiples. If you are preparing for a sale, use Prepare a Dental Practice for Sale as the operating checklist.

Begin with the purpose of the valuation

There is no single number that is correct for every purpose. A planning estimate, partner buy-in, doctor-to-doctor sale, DSO offer, divorce, estate matter, and tax filing may require different assumptions, procedures, or standards of value.

The IRS’s closely held business guidance captures the central principle: no formula applies to every valuation. The analysis should consider the business’s history, financial condition, earning capacity, goodwill, risk, industry outlook, and relevant market evidence. The IRS also recognizes the asset, market, and income approaches as the three broad valuation approaches (IRS valuation guidance; IRS valuation job aid).

Before calculating anything, define:

  • Why the practice is being valued;
  • The valuation date;
  • The likely buyer—another dentist, an associate, a local group, or a DSO;
  • What is included in the transaction;
  • Whether the real estate is included, leased separately, or excluded; and
  • Whether you need a planning estimate or a formal professional opinion.

An online valuation can orient an owner and identify high-impact questions. A number used in a transaction, dispute, tax matter, or financing decision may require an independent valuation and advice from a dental CPA and transaction attorney.

The three valuation approaches

1. Income approach

The income approach values the future economic benefit a buyer expects to receive. A simplified market-multiple calculation looks like this:

Indicated practice value = normalized earnings × selected multiple

A more formal analysis may capitalize sustainable earnings or discount projected cash flows. In every version, the important word is normalized. The buyer needs to understand what the practice is likely to earn after owner-specific expenses, unusual events, and the seller’s labor are treated appropriately.

2. Market approach

The market approach compares the practice with sales of similar practices. The challenge is determining whether they are actually comparable.

A solo general practice sold to another working dentist is not automatically comparable with a multi-location specialty group acquired by a DSO. Collections, profitability, growth, payer mix, provider mix, geography, facility capacity, owner dependence, and transaction structure all affect comparability.

When evaluating a market multiple, ask:

  • Is it based on collections, SDE, EBITDA, or adjusted EBITDA?
  • Does it reflect asking prices or closed sales?
  • Which years are included?
  • Is the figure a median, average, or range?
  • What types and sizes of practices are represented?
  • Does the reported price include real estate, accounts receivable, working capital, seller financing, contingent payments, or retained equity?

3. Asset approach

The asset approach considers the value of equipment, furniture, supplies, technology, and other assets less applicable liabilities. It can be important for a start-up, distressed practice, or asset-only transaction. A healthy operating practice is usually worth more than the resale value of its equipment because value may also reside in workforce, systems, patient relationships, trade name, and going-concern value.

The distinction becomes concrete at closing. The IRS treats the sale of a business for a lump sum as the sale of separate assets, and buyer and seller generally allocate consideration among them. Goodwill and going-concern value are part of that allocation (IRS: Sale of a Business; IRS Form 8594 instructions). The allocation can affect each party’s tax outcome, so it should be negotiated with tax and legal advisers rather than guessed in an online estimate.

A practical five-step valuation process

Step 1: Reconcile collections and financial statements

Gather three to five years of tax returns and year-end financial statements, plus trailing-12-month and year-to-date results. Reconcile production, adjustments, and collections to the practice-management system. Identify whether recent results reflect the practice’s current run rate.

The ADA advises sellers to prepare five years of tax returns and financial statements, a current fee schedule, accounts receivable and collection data, provider production, monthly hours, service mix, recare information, lease or mortgage documents, and equipment details (ADA practice-valuation checklist; ADA: What Makes a Successful Sale).

Recent performance matters. The ADA specifically cautions that buyers and financiers focus on current numbers and trends; a seller who reduces hours and collections before a sale should expect that choice to affect what a buyer can support (ADA: 10 Must-Dos to Prepare Your Practice for Sale).

Step 2: Normalize earnings

Taxable income and accounting net income do not automatically equal buyer cash flow. Review owner compensation, personal expenses, related-party rent, one-time costs, noncash charges, and revenue or expenses that will change after the sale.

The goal is not to add back every expense that feels optional. It is to estimate sustainable earnings under the likely buyer’s operating model. Every adjustment should have a reason, documentation, and a clear answer to this question: Will the buyer actually avoid this cost after closing?

Step 3: Select the correct earnings lens

For a smaller owner-operated practice sold to another working dentist, seller’s discretionary earnings, or SDE, may be the useful starting point. SDE is intended to estimate the total economic benefit available to one owner-operator.

For a larger, associate-driven, multi-location, or DSO-targeted practice, adjusted EBITDA is usually more relevant. It treats the clinical and management labor required after the seller leaves as ongoing expenses.

Do not apply an EBITDA multiple to an SDE number. The definitions and buyer economics differ. See SDE vs. EBITDA for Dental Practices for a worked example.

Step 4: Select a market-supported range and cross-check it

The ADA describes 65%–85% of average three-year collections as a very rough starting range, then immediately recommends supporting the price with financials and a professional valuation (ADA sale guidance).

Current BizBuySell data provide a useful second lens. For dental practices reported sold nationally from 2021 through 2025, the middle 50% of sale-price multiples ranged from 0.51× to 0.86× revenue and 1.60× to 3.37× owner earnings, with medians of 0.70× and 2.48×, respectively (BizBuySell dental valuation benchmarks).

These are market observations, not instructions to multiply your numbers by the median. BizBuySell’s data are reported transactions on its marketplace, mix different dental practice types and locations, and do not disclose a transaction count on the public benchmark page. Use them to frame a range, then compare your practice’s economics and risks with the represented businesses.

Step 5: Translate practice value into the economics of a deal

Practice value, cash at closing, and the seller’s net proceeds are different numbers. Debt payoff, working capital, accounts receivable, transaction costs, taxes, asset allocation, real estate, seller notes, earnouts, retained equity, and post-closing employment can all change the result.

A higher headline offer can carry more conditions or delayed consideration. Compare what is paid, when it is paid, what remains at risk, and what the seller must do after closing.

What buyers will examine

Buyers and lenders usually want to understand:

  • Collections and profitability trends;
  • Production by dentist, hygienist, procedure, and location;
  • Active-patient, new-patient, recare, and case-acceptance trends;
  • Payer and fee mix, write-offs, and collection performance;
  • Staff compensation, tenure, and retention risk;
  • Owner clinical production and management responsibilities;
  • Lease transferability, rent, and remaining term;
  • Equipment condition and near-term capital needs;
  • Referred-out procedures and realistic growth capacity; and
  • The documentation supporting every proposed add-back.

The broader dental economy makes this scrutiny more important. ADA HPI reports that average GP dentist income was $215,320 in 2025 and that, over a five-year period, practice revenue rose 1.4% while expenses rose 4.9% (ADA HPI income and revenue trends). That national “fiscal squeeze” does not dictate one practice’s value, but it reinforces why buyers care about current, sustainable margins rather than collections alone.

What makes a dental valuation defensible

A dental practice is not worth one universal percentage of collections. Its value depends on normalized, transferable earnings; the buyer and purpose; current market evidence; the durability of patients, people, and systems; and the terms of the transaction.

Use a valuation estimate to understand the plausible range and the variables moving it. Use an independent dental valuation professional, CPA, attorney, and lender when the result will support a real transaction or legal decision.
