Dental Practice Brokers Charge 8-10% Commission. Negotiate It.

One point of commission on a $1.6M practice is $16,000. A tail clause that lets your broker collect the full fee on a buyer you introduced yourself is $160,000, and almost every seller we talk to has spent their negotiating energy on the first number while signing the second without reading it.

Here is the claim an informed owner can argue with: on any practice collecting north of $1.5M, a flat percentage commission is the worst-priced line item in the entire transaction, and a broker who refuses to tier it is telling you exactly how little work they expect to do. Plenty of transition consultants will tell you the flat fee aligns incentives, that a broker fighting for the last $50,000 of purchase price earns their 10%, and that sellers who haggle get the B-team and a listing that sits. We think that argument holds for small, hard-to-sell practices and collapses for healthy ones.

Ten Percent Is a Posted Price, Not a Market Price

Start with what the profession's own trade body says out loud. The ADA puts it plainly: business brokers "generally charge about 10% of the value of the practice" as their fee, and in the same breath notes that some brokers will negotiate this fee downward depending on the circumstances of your practice. That sentence is doing a lot of work. It is the ADA telling you, in the gentlest possible language, that the number on the listing agreement is an opening offer.

Brokers themselves publish the tiering. One transition firm's own rate explainer lays out commission bands by practice size: roughly 8% to 12% for practices under $1M, falling to 5% to 8% once you pass $3M. Read that twice. The industry has already conceded in writing that the percentage should fall as the deal gets bigger. If you own a $2.6M practice and your listing agreement says a flat 10%, you are not paying the market rate. You are paying the rate for a $700,000 practice in a town with one buyer.

The reason the sliding scale exists is that broker cost does not scale with practice size. The valuation, the prospectus, the data room, the buyer calls, the lender introductions, the three months of chasing a reluctant associate: that workload is close to identical whether the practice sells for $900,000 or $2.9M. The second deal just pays triple for it.

A $2.2M Sale, $28,000 of Fee Daylight

Run the arithmetic on a real-sized general practice. Say you collect $2.2M, the practice sells at that number, and the listing agreement is a flat 10%. Your broker fee is $220,000.

Now price the same deal on the Double Lehman structure, which is the tiered formula brokers and sellers have used across industries for decades: 10% of the first $1M, 8% of the second, 6% of the third, 4% of the fourth, 2% on everything above $4M, per the documented mechanics of the formula. On $2.2M that is $100,000 on the first million, $80,000 on the second, and $12,000 on the remaining $200,000, for a total of $192,000.

The gap is $28,000.

Broker commission is a cost of sale, so saving it adds to your taxable gain. At a combined federal and state rate around 28% on the proceeds, that $28,000 is worth roughly $20,160 in your pocket.

We will note that the broker-side write-up on this is more optimistic than ours. That same transition firm's article says moving a $2M deal from a flat 10% to a 10-8-6-4-2 tiered structure saves more than $40,000, which implies tighter breakpoints than the classic million-dollar tiers we used. Fine. Take the conservative version. Twenty thousand dollars of after-tax money for one redline and one uncomfortable phone call is still the best-paid hour of your entire exit.

The Fee You Pay on Money You Haven't Received

This is the structural problem the percentage debate hides, and it is where DSO deals mangle sellers.

Suppose the headline number is $2.5M. Of that, $500,000 is rollover equity in the buyer's holding company and $300,000 is an earnout tied to two years of collections performance. Cash at close is $1.7M.

A flat 10% on enterprise value, payable at close, is $250,000.

Measured against the money that actually hits your account at closing, that fee is 14.7%.

You are paying cash today on equity that may be worth half as much in four years and on an earnout you might miss entirely. If the earnout washes out and the rollover gets marked down, you paid a quarter of a million dollars in commission on $2M of real consideration, which is 12.5%.

Our view: the fee should follow the money. Commission on cash at close, payable at close. Commission on contingent consideration, payable when and if you receive it, at the same tiered rate. We would not sign a listing agreement that bills you at close for dollars that are still a maybe, and we have yet to hear a defense of that structure that survives being said out loud.

What Most Owners Get Wrong: Arguing About the Percentage

The owner who makes this mistake is specific and recognizable. They are 58 to 65, solo or two-chair, selling once in a lifetime, and they got the broker's name from their CPA or a study club peer who had a good experience four years ago. They have never read a listing agreement before. They negotiate the headline percentage down from 10% to 9%, feel like a shrewd operator, and sign a document whose remaining clauses are worth ten times what they just won.

The clauses that matter more than the point:

• The tail. How long after the listing expires can the broker still collect if you sell? Twelve months is common. Twenty-four happens. If a DSO that contacted you directly two years ago buys the practice six months after your listing lapses, a broad tail hands them the full fee for zero work.
• Carve-outs. Name every buyer you have already talked to: your associate, the group three towns over, the DSO rep who has emailed you twice, your brother-in-law's partner. If a named party buys, the fee is reduced or zero. Brokers will fight this. Fight back, because this one clause is worth more than three points of commission.
• What triggers payment. "Procuring a ready, willing and able buyer" is not the same as "closing." You want the fee tied to funded closing, full stop.
• Dual representation. If the brokerage also represents the buyer or has a standing relationship with the acquiring group, who are they actually working for? Get the disclosure in writing and get the fee split in writing.
• A dollar ceiling. Cap the total fee. A $150,000 cap on a $2.5M sale is an effective 6%, which is inside the published band for that size anyway.

Owners argue about the point because the point is a number they understand. The clauses are where the money is.

Why 13% DSO Affiliation Changed Your Bargaining Position

The flat 10% was priced for an era when finding a qualified buyer for a general practice was genuinely hard work. That era is over for anything healthy. ADA Health Policy Institute data shows DSO affiliation among dentists climbing from 8.8% in 2017 to 10.4% in 2019 to 13% in 2022. Behind that curve sits an entire class of institutional buyers with acquisition teams, committed capital and collections targets, actively hunting practices in the exact size band most sellers occupy.

That does not mean you should sell to a DSO. It means the broker's hardest historical task, producing a credible buyer, got dramatically easier for well-run practices, and the price of that task has not moved. When the supply of buyers goes up and the fee stays flat, the seller is subsidizing a search that no longer takes much searching.

When 10% Is Fair and You Should Pay It

We are not going to pretend every broker fee is padded. If you collect $650,000, run 40% write-offs on a PPO-heavy book, sit 90 minutes from a metro area, and have no associate and no hygiene department, your practice is hard to sell. Your broker may spend eighteen months and forty buyer conversations to find one person who will take it with bank financing. That is a 10% to 12% job, and grinding that broker to 7% buys you a listing nobody is working.

Same answer if the broker is doing genuine repair work: cleaning up your books, restructuring the associate's comp before diligence, fixing a lease that has fourteen months left on it. That work changes the purchase price by more than the fee. Pay for it.

The negotiation is not "pay me less." It is "price this deal like the deal it is." A clean $2.4M practice with three hygienists, a 24-month collections trend going the right way, a transferable lease and two unsolicited DSO inquiries already in your inbox is not a 10% problem.

How the Ask Actually Sounds

Owners avoid this conversation because they do not know the words. Here they are, and they are not aggressive: "I want to work with you. Before I sign, I'd like the fee tiered rather than flat, 10-8-6 on the first three million, commission on contingent consideration paid as I receive it, a twelve-month tail, and these three parties carved out. Everything else in your agreement is fine."

A good broker will push on one or two items and sign. A broker who tells you the fee is non-negotiable is contradicting the ADA's own guidance and their own industry's published rate card, and that is useful information about how the rest of your deal will go.

Do This Before You Sign the Listing Agreement

Get two listing agreements, not one, and read the tail and trigger clauses before you look at the percentage. Write down every buyer who has ever contacted you about your practice and demand they be named as carve-outs. Ask for the fee tiered and ask for contingent consideration billed on receipt, in one email, in writing. Then have a transactional attorney who is not your broker's regular referral read the whole thing for ninety minutes, because that is the cheapest money you will spend on this transaction.

What we are watching next: whether DSO buyers start paying broker fees directly on the buy side, the way commercial real estate shifted. If that becomes standard, the seller-paid 10% looks indefensible overnight. Until then, the only thing standing between you and $20,000 to $60,000 is a sentence you have to say to someone you like.

Before you talk to any broker, you need a defensible number for what the practice is actually worth, because the fee argument only matters once you know the base it applies to. Use our free practice valuation calculator to run your own numbers on collections, EBITDA and transition-adjusted value, then take that figure into the listing conversation instead of taking the broker's.
