AI Summary
  • Most general practices sold to another dentist land around 65 to 80 percent of a year's collections, but profit decides where in that range you fall.
  • A valuation starts with three years of collections, then normalizes the books: personal and one-time expenses come out, and your pay is replaced with what an associate would cost.
  • That cleaned-up profit gets a multiple. Private buyers often pay around 1.5 to 2 times SDE. DSOs price single-doctor practices around 5 to 7 times adjusted EBITDA, with part of it paid in equity and earnouts.
  • Goodwill (your patients, team, location and reputation) is most of the price. Owner dependence, a short lease and slipping collections cut it fast.
  • Starting October 1, 2026, SBA lenders have to order their own independent valuation when they finance a practice purchase, so a price your numbers can't support gets exposed.

Every dentist I sit down with wants to know the same thing before we talk about anything else. What's my practice worth?

It's a fair question, and the honest answer is that there's no single formula. Two practices that collect exactly the same amount can sell for very different prices. One has a full hygiene schedule, ten years left on its lease and a team that's been together forever. The other runs entirely on the owner, with overhead eating 72 cents of every dollar.

So instead of handing you one magic number, I'll walk you through how to value a dental practice the way appraisers, lenders and buyers actually do it. You'll see the quick rules of thumb, the math behind them, and what moves the number in either direction. I'll carry one sample practice through the whole thing so you can see real numbers instead of theory.

What Dental Practices Actually Sell For

If you want a ballpark before we get into the details, here it is. A typical general practice sold to another dentist goes for somewhere around 65 to 80 percent of one year's collections. One buyer-side firm pooled more than 1,100 sales from 2005 to 2019 and found the average landed right around 77 percent of the prior year's collections.

Treat that as a starting point, not an answer. Smaller practices (think under $400,000 in collections) tend to sell below the average, and practices collecting $750,000 or more tend to sell above it. Specialty practices and practices sold to DSOs follow different math entirely, which we'll get to.

The range is wide for a simple reason. Buyers aren't really paying for collections. They're paying for the profit those collections leave behind, and for how confident they are that the profit sticks around after you leave. If you want more on the "worth" question specifically, our guide to how much a dental practice is worth goes deeper.

Step 1. Start With Collections, Not Production

Production is what you billed. Collections is what actually hit the bank. Valuations use collections, because nobody can make a loan payment with write-offs.

Expect an appraiser to ask for at least three years of collections plus your year to date. The trend matters as much as the total. A practice that grew from $950,000 to $1.2 million over three years looks very different from one that slid from $1.4 million to $1.2 million, even though both collected $1.2 million last year. Buyers read a declining trend as a forecast, and they price it that way.

Break your numbers out by provider, too. What you personally collect, what hygiene brings in and what any associates produce all matter in the next step.

Step 2. Find the Real Profit

Your tax return is designed to show as little profit as legally possible. That's great for your tax bill and terrible for your sale price. So the next step is normalizing, which just means rebuilding your profit and loss statement the way it would look for a new owner.

The adjustments usually fall into a few buckets:

  • Personal expenses. Your car, your phone, a family member paid more than the job would normally pay, travel that was more personal than professional. These get added back.
  • One-time costs. The flooded sterilization room, a legal settlement, the year you paid a fill-in dentist while you recovered from surgery.
  • Interest, depreciation and amortization. These reflect how you financed and bought things, not how the practice performs.
  • Rent, if you own the building. If you're paying your own real estate company above-market rent, it gets adjusted to what a normal tenant would pay.
  • Your own pay. This is the big one. Your salary and draws get added back, then the cost of replacing your dentistry at a market associate rate comes back out. That's usually somewhere around 30 to 35 percent of what you personally collect.

After those adjustments you'll have two numbers worth knowing. Seller's discretionary earnings (SDE) is everything a single owner-dentist takes home before paying themselves a dime. Adjusted EBITDA goes one step further and subtracts that market-rate dentist, so it shows what the practice earns as a business. Private buyers tend to think in SDE. DSOs think in EBITDA. We have a whole article on seller discretionary earnings if you want the long version.

Here's our sample practice run through the process:

Sample Practice: From Collections to Real Profit

Annual collections $1,200,000
Overhead as reported (everything except the owner's pay) -$750,000
Add-backs found in that overhead (car, phones, family payroll, a one-time repair) +$50,000
Seller's discretionary earnings (SDE) $500,000
Market-rate dentist to replace the owner (30% of the $800,000 the owner collects) -$240,000
Adjusted EBITDA $260,000

Hygiene brings in the other $400,000 of collections. Adjusted EBITDA works out to about 22% of collections, right where a well-run general practice tends to sit.

Step 3. Apply the Dental Practice Valuation Methods

Once you know the real profit, there are three broad ways to turn it into a price. A good appraiser runs more than one and looks at where they agree.

The Market Approach: What Similar Practices Sold For

This is where the percent-of-collections rules come from. The appraiser looks at recent sales of comparable practices and how they priced. It's intuitive, and it's the method most dentists have heard of. Its weakness is that it ignores profit completely. At 70 percent of collections, our sample practice comes in around $840,000.

The Income Approach: What the Profit Is Worth

This one prices the earnings. For a practice sold to another dentist, a common version is a multiple of SDE, usually somewhere around 1.5 to 2 times. For our sample practice that's $750,000 to $1 million. Appraisers also use capitalized earnings and discounted cash flow models, which are more formal ways of asking the same question: what is a stream of profit like this worth to someone taking on the risk of buying it?

The Asset Approach: What the Stuff Is Worth

Add up the fair market value of the equipment, technology, furniture and supplies. For a healthy practice this lands far below the other two, because it leaves out goodwill, which is the value of the patients, team, reputation and location you've built. It's mostly useful as a floor, or for a practice that isn't very profitable.

Market approach

$840,000

70% of collections, based on comparable sales

Income approach

$750K to $1M

1.5 to 2 times SDE of $500,000

Asset approach

About $170,000

Equipment, technology and supplies. A floor, not a price.

Where it lands: about $850,000, or roughly 71% of collections. Around 80% of that price is goodwill, which is normal for a healthy practice.

Goodwill deserves its own conversation, because it's usually the biggest asset you're selling and the one that's easiest to damage. Our guide to dental practice goodwill covers how it's measured and how it's taxed.

The Dental Practice Valuation Rule of Thumb (and Why It Can Mislead You)

Rules of thumb are fine for a gut check and risky as a price. Here's the problem in one example. Two practices each collect $1 million. One runs 55 percent overhead, the other runs 72 percent. A percent-of-collections rule says they're worth the same. A buyer looking at profit, and a lender checking whether the loan gets paid, see something very different.

Practice A
Collections$1,000,000
Overhead55%
SDE$450,000
Value at 1.75x SDEAbout $790,000
Practice B
Collections$1,000,000
Overhead72%
SDE$280,000
Value at 1.75x SDEAbout $490,000

Same collections, a $300,000 difference in value. It cuts the other way, too. A study published in Dental Economics compared 46 formal appraisals against the popular "0.8 times revenue" rule and found the appraised values came in about 62 percent higher on average. Those were mostly larger practices, so don't expect that kind of bump on a typical solo office. The lesson still holds: price off a rule of thumb and you can leave real money on the table, especially if your practice is very profitable.

Dental Practice Valuation Multiples: Private Buyer vs. DSO

Who's buying changes how the number gets built.

A dentist buying a practice is almost always financing it, so the price has to leave enough profit to cover the loan payment and still pay the new owner a living. That's why doctor-to-doctor deals stay anchored to collections and SDE. Traditionally that has worked out to roughly 3 to 4 times EBITDA. If you're on the buying side, our guide on how to finance a dental practice shows how lenders size these loans.

A DSO (dental service organization) prices on adjusted EBITDA. For a single-doctor practice the multiple is commonly somewhere around 5 to 7 times, and large multi-location groups can go well beyond that. For our sample practice, 5 to 7 times $260,000 is $1.3 million to $1.8 million on paper.

Before you start shopping for a boat, read the fine print. DSOs knock a turn or two off the multiple when one dentist produces most of the revenue, and in our sample practice the owner collects two thirds of it. A DSO offer also isn't all cash. It's common to see roughly 60 to 75 percent paid at closing, with the rest in rollover equity (stock in the DSO) and earnouts tied to hitting targets after the sale. And you'll usually keep working as an employee for a few years, at the same market rate that got subtracted in the EBITDA math.

Private dentist buyer
  • Prices on collections and SDE
  • Sample offer: about $850,000
  • Paid at closing, funded by the buyer's loan
  • You stay for a short transition, then you're done
DSO buyer
  • Prices on adjusted EBITDA of $260,000
  • After a key-person discount (4 to 5 times): $1.04M to $1.3M
  • Cash at closing (60 to 75%): roughly $625K to $975K
  • The rest in equity and earnouts, and you keep working for a few years

Notice how close the cash at closing can land to the private offer. Neither buyer is always better. It depends on your timeline, how much you want to keep practicing and how you feel about betting part of your price on a DSO's future. We break down the tradeoffs in selling your dental practice to a DSO, and if you're fuzzy on what a DSO actually is, start with what a dental support organization is.

What Pushes the Value Up or Down

This is where two practices with the same profit can still end up far apart. Buyers are pricing risk, and these are the things that make them nervous or confident:

  • Your collections trend. Growing beats flat, and flat beats shrinking. Buyers extend whatever direction you're headed.
  • Overhead. Most general practices run somewhere around 60 percent. Get into the mid 50s and buyers get excited. Push past 70 and they get nervous.
  • Hygiene and recall. A busy hygiene schedule producing somewhere around a quarter to a third of collections is recurring revenue a new owner can count on.
  • Active patients and new patients. Active usually means seen in the last 18 to 24 months. A steady flow of new patients proves the practice isn't just coasting on old relationships.
  • Payer mix. Strong fee-for-service revenue and decent PPO fees help. Heavy reliance on low-paying plans hurts. Our HMO vs. PPO comparison explains why.
  • Owner dependence. If patients only want to see you, a buyer worries they'll leave when you do. An associate, or at least a team that runs without you, protects your goodwill.
  • The lease and location. Lenders want to see years left on the lease, ideally with renewal options, because their loan assumes the practice stays put. Visibility, parking and local demographics shape what a new owner can build.
  • Equipment and technology. Modern, well-kept equipment helps. Deferred maintenance gets subtracted from what a buyer will pay, usually at a steeper price than it would have cost you to fix.
  • Your team. A stable, long-tenured staff lowers transition risk. A revolving door raises it.
  • Room to grow. An empty operatory, services you currently refer out or limited hours all give a buyer upside they're willing to pay for.

What You'll Need for a Dental Practice Valuation

Whether you use a calculator, a broker or a certified appraiser, pulling these together ahead of time makes the process faster and the result more accurate:

Valuation Document Checklist
  • Three years of tax returns and P&L statements, plus year to date
  • Production and collections by provider and by procedure code
  • Active patient count and monthly new patients
  • Accounts receivable aging report
  • Fee schedule and the insurance plans you participate in
  • Payer mix: fee-for-service, PPO and any HMO or Medicaid
  • Your lease, or a note that you own the building
  • Equipment list with rough ages
  • Staff roster with roles, tenure and pay
  • A list of the add-backs you plan to claim, with receipts

One tip: make sure the story your P&L tells matches the story your tax returns tell. If they don't agree, the tax returns usually win, and that's the version a lender will check.

Dental Practice Appraisal vs. Valuation: Which Do You Need?

People use these words like they mean the same thing. They don't, and the difference matters.

  • A calculator estimate or broker's opinion of value. Quick and usually free. It's perfect for planning, and for pricing a practice before it goes on the market.
  • A certified appraisal. A formal report from a credentialed analyst. You'll want one for a partner buyout, a divorce, an estate or anything that could end up in court. It typically costs a few thousand dollars or more, depending on the size and complexity of the practice.
  • The lender's valuation. If your buyer is financing the purchase, their lender will want its own number, and this one has teeth.

That last point is getting stricter. Under SBA lending rules that take effect October 1, 2026, a lender making an SBA 7(a) loan for a practice purchase has to order its own independent valuation from a credentialed appraiser. It can't use a valuation prepared for you or for the buyer. It checks the numbers against your IRS tax transcripts. And if the price is higher than the appraised value, the buyer has to cover the gap with their own money. Deals of $3 million or more also need a separate quality of earnings review.

So an inflated asking price doesn't just scare off buyers. It can fail the lender's valuation and sink a deal you thought was done. Price it right the first time.

How to Increase the Value of Your Dental Practice Before You Sell

The best time to get a valuation is two or three years before you want to sell, not two weeks before. That gives you time to fix what it finds. The moves that tend to pay off most:

  • Clean up the books early. Stop running personal expenses through the practice a couple of years out, so your returns show the real profit.
  • Fill the hygiene schedule. Tighten recall and reactivate overdue patients. It's the cheapest growth you'll ever find.
  • Lock in the lease. Negotiate a long term with renewal options before you list, not during the sale.
  • Make yourself less essential. Bring on an associate, or at least build systems and a team that don't need you in every room.
  • Deal with deferred maintenance. Fix or replace the equipment a buyer will flag anyway.
  • Don't coast. Collections that slide in your last year or two will cost you at the closing table.

Timing matters too. Our guides on the best time to sell a dental practice and preparing to sell go step by step. And since what you actually keep depends on how the price gets allocated, it's worth reading up on the tax consequences of selling a dental practice before you sign anything.
