Dental Practice Valuation Multiples in Illinois (2026)

A well-run general dental practice in Illinois commonly trades between 1.5× and 2.5× annual collections, and the gap between the low end and the high end can mean $400,000 or more on a $1M-revenue practice. If you're a solo or multi-location owner thinking about selling, merging, or bringing on a partner in 2026, the numbers below are the starting point. This page breaks down current valuation multiples, Illinois-specific demand drivers, and the math that actually matters when you sit across the table from a buyer.

The Numbers: Illinois Benchmarks

• Revenue multiples (general practice): Illinois general practices typically trade at 65%–85% of trailing twelve-month collections, with the midpoint around 70%–80% for solo locations. Practices with strong hygiene recall and low PPO dependency tend to sit at or above the upper bound.
• Revenue multiples (specialty): Oral surgery, periodontics, and pediatric practices in desirable Illinois metros commonly report multiples of 85%–110%+ of collections, driven by referral network value and higher per-visit revenue.
• EBITDA multiples (owner-operated GP): Industry surveys suggest 3×–5× adjusted EBITDA for single-location general practices. Multi-location groups with delegated management and consistent earnings can push into the 5×–7× range, particularly when DSOs are the buyers.
• EBITDA multiples (DSO platform acquisitions): When a DSO is acquiring an Illinois group as a platform (not a tuck-in), multiples of 6×–9× adjusted EBITDA have been reported in recent transactions, though these deals typically involve practices doing $3M+ in annual revenue across multiple locations.
• Goodwill as a percentage of sale price: In Illinois practice transitions, goodwill commonly represents 70%–85% of the total purchase price, with hard assets (equipment, supplies) making up the remainder. Higher goodwill percentages generally reflect stronger patient retention and brand equity.
• Days on market: According to dental brokerage estimates, well-priced practices in the Chicago metro and collar counties typically sell within 90–180 days. Downstate practices and rural locations may take 6–12+ months, especially if the buyer pool is thin.
• Seller financing prevalence: Industry data suggests that 15%–30% of Illinois practice sales still involve some seller financing component, particularly in smaller transactions under $500K where bank underwriting is tighter or the buyer is a recent graduate.

Why Illinois Is Different

DSO activity is accelerating in the Chicago metro. Illinois is one of the top ten states by DSO penetration, and the trend is intensifying. Large consolidators. Aspen, Heartland, Pacific, and regional players like Dental Care Alliance, are actively acquiring in DuPage, Lake, Will, and Cook counties. This buyer competition puts upward pressure on multiples for practices that fit the DSO acquisition profile: $1M+ collections, multiple operatories, delegated hygiene, and a clean payer mix. If your practice checks those boxes and you're within 45 minutes of a major Illinois highway corridor, you are likely fielding more inbound interest in 2026 than you were even two years ago.

Demographics cut both ways. The Chicago-Naperville-Elgin metro area has roughly 9.4 million people (U.S. Census Bureau estimates), and suburban population growth in Will, Kendall, and McHenry counties continues to create demand for dental services. But Illinois as a whole has experienced flat-to-declining population growth over the past decade, and many downstate communities are losing residents. That means a practice in Bloomington or Decatur faces a fundamentally different buyer market than one in Schaumburg or Oak Park. Buyers pay for patient volume trajectories, not just current production, and in shrinking markets, multiples compress.

Insurance mix and regulation matter here. Illinois has a large Medicaid dental population, and practices with significant Medicaid revenue (commonly reimbursed at 40%–60% of UCR, according to ADA Health Policy Institute data) will see lower multiples unless the volume is enormous and operationally efficient. On the regulatory side, Illinois requires a licensed dentist to own a dental practice, which limits direct DSO ownership structures and pushes most consolidators toward management service organization (MSO) models. This doesn't reduce deal flow, but it does affect deal structure, and structure affects your after-tax proceeds. Illinois's flat state income tax rate of 4.95% (as of this writing) is straightforward, but sellers should model the federal and state capital gains impact of asset-sale versus stock-sale structures carefully.

Operator Math

Let's make this concrete. Consider a solo general practice in suburban Cook County doing $1.2M in annual collections with an adjusted EBITDA of $360,000 (a 30% margin, which is typical for a well-managed owner-operator GP).

At a 4× EBITDA multiple, the practice is valued at $1,440,000.

Now suppose you spend the 12–18 months before a sale improving operational efficiency, tightening your hygiene reappointment rate, renegotiating lab fees, and reducing no-shows. You move adjusted EBITDA from 30% to 35%, which on $1.2M in collections means EBITDA rises to $420,000.

At the same 4× multiple, the practice is now valued at $1,680,000.

That 5-percentage-point shift in EBITDA margin, achieved without adding a single new patient, is worth $240,000 at closing. And here's the compounding effect: a buyer looking at a 35% margin practice often views it as better-managed and lower-risk, which can push the multiple itself from 4× to 4.5×. At 4.5× and $420K EBITDA, you're at $1,890,000, a $450,000 improvement over where you started. That's the difference between retiring comfortably and retiring early.

This is why we tell every Illinois practice owner the same thing: multiples get the headlines, but margins drive the outcome.

Common Mistakes

• Using gross production instead of adjusted collections for your baseline. Buyers care about money that actually hits the bank account. If your collections rate is 92% and you're quoting your $1.3M production number, you're setting yourself up for a painful renegotiation mid-diligence when the buyer's CPA recalculates on $1.196M.
• Not normalizing owner compensation before calculating EBITDA. If you pay yourself $350K but a hired associate would cost $180K, the buyer will add back the difference, but only if you present it clearly. Failing to produce a clean, normalized P&L is the single fastest way to get lowballed or lose a buyer's interest entirely.
• Ignoring the impact of your payer mix on the multiple. A practice with 60% fee-for-service revenue and 25% PPO will command a meaningfully higher multiple than one with 70% PPO and 15% Medicaid, even if top-line collections are identical. Illinois buyers, especially DSOs, model reimbursement risk. Know your payer breakdown by revenue, not just by patient count.
• Waiting until you're burned out to start the exit process. The best time to sell is when the practice is growing and you still have energy to support a transition. Buyers in Illinois routinely ask for 6–24 month associateships or consulting agreements post-close. If you're already one foot out the door, you have less use to negotiate transition terms and earnout structures.
• Assuming your CPA or financial advisor understands dental-specific transaction structures. The difference between an asset sale and an equity sale, the allocation between goodwill and tangible assets, covenant-not-to-compete valuation, these have significant tax consequences specific to dental. Work with a dental transaction attorney and a CPA who has closed at least a dozen practice deals. Illinois's MSO structures add another layer of complexity that generalists frequently mishandle.
