The Truth About Dental Practice Overhead Percentage (Real Benchmarks)

| July 15, 2026

Most dentists obsess over the wrong number. They chase top-line collections while the number that actually decides their freedom hides in plain sight on the P&L: overhead. Get it wrong and you can run a $2M practice and still feel broke. Get it right and a smaller practice can hand you a bigger life.

Here is the truth nobody at the dental school reunion will tell you.

What is a healthy dental practice overhead percentage?

For a general practice, a strong target is 60–65% overhead excluding doctor compensation. That means for every dollar collected, roughly 60 to 65 cents covers rent, staff, supplies, lab, and everything else it takes to keep the lights on — before you pay yourself as the dentist.

Break it down and the benchmarks look like this:

• Staff / payroll: 25–28% of collections
• Rent / facility: 5–7%
• Dental supplies: 5–6%
• Lab bills: 6–10% (procedure-mix dependent)
• Marketing: 3–5% in a mature practice; higher when you are ramping

If your overhead is creeping toward 75% or higher, you do not have a revenue problem. You have a leak. And leaks compound.

Why is my overhead so high even though I’m busy?

Because busy is not the same as profitable. Pete Boulden puts it in tactical terms: your fixed costs — rent, base payroll, equipment — do not care how many patients walked in the door today. They are the same whether you produce $40,000 this month or $120,000. That is the brutal math of a low-volume week and the beautiful math of a great one.

This is the single most misunderstood lever in dentistry. When production drops, overhead percentage spikes — not because you spent more, but because you spread the same fixed cost over fewer dollars. Chairs sitting empty are the most expensive thing in your building.

On the Bulletproof Dental Practice Podcast, this comes up constantly: the practices bleeding profit are rarely the ones spending recklessly. They are the ones with unfilled schedules, soft case acceptance, and a team that has never been shown the numbers.

Should I cut costs or grow production to fix overhead?

Grow. Almost always, grow.

You cannot cut your way to a great practice. There is a floor on how cheap your supplies, rent, and team can get before quality — and morale — collapses. But there is no ceiling on production per visit, case acceptance, and same-store growth.

One of the recurring themes across 450+ podcast episodes: the fastest path to a lower overhead percentage is a bigger denominator. Fill the schedule you already pay for. Raise case acceptance on the patients already sitting in your chairs. That is same-store growth — and it drops almost entirely to the bottom line because the fixed costs are already covered.

What is the difference between overhead and profit margin?

Overhead is what it costs to operate. Profit is what survives after. In a private practice, your true take-home has two parts: your pay as the clinician (the dentist doing the dentistry) and your return as the owner (the entrepreneur who took the risk).

Most dentists blur these together and never know if their business is actually healthy. Separate them. Pay yourself a fair clinical wage as a line item, then look at what the business earns on top. If the business only makes money because you are working 40 clinical hours, you do not own a practice — you own a job with overhead.

This is the distinction Craig Spodak drives home: the goal was never just a profitable chair. The goal is a business that produces profit whether or not your hands are in a mouth. That is the difference between a paycheck and freedom.

How do the numbers compare to a DSO?

Here is where it gets interesting — and where the corporate pitch falls apart. DSO recruiters love to brag about squeezing profitability through scale and group purchasing. And yes, at massive scale you can shave points off supply and negotiate national contracts.

But a well-run private practice at 60–65% overhead, with strong case acceptance and a full schedule, keeps more per dollar than most dentists ever realize — and keeps all of it. No corporate skim. No production quotas dictating your treatment plans. No stranger in a boardroom deciding your fee schedule.

The independent dentist who masters their own P&L does not need to sell to a DSO to win the numbers game. They win it in their own building, on their own terms. Clinical excellence is the floor. The life you build on top of it is the point.

What overhead numbers should I track every single month?

Stop looking at overhead once a year at tax time. That is like checking the scoreboard after the game is over. Track these monthly:

• Overhead % (ex-doctor): total operating cost ÷ collections
• Payroll as % of collections: your biggest and most controllable line
• Production per visit: the quiet lever that fixes overhead without adding a single new patient
• Collections vs. production: a gap here means money is walking out the door uncollected
• Supply and lab % by month: catch creep before it becomes a habit

What gets measured gets managed. A dentist who reviews these five numbers monthly will out-earn a more talented clinician who never opens the P&L. It is not close.

You are not supposed to figure this out alone

Dentistry trained you to fix teeth. It taught you almost nothing about reading a P&L, benchmarking overhead, or building a business that pays you when you are not in the building. So most dentists guess — and quietly wonder why the busy years never turned into wealth.

They do not have to. Inside the Bulletproof Mastermind, owners share real numbers — real overhead, real payroll percentages, real profit — with peers who refuse to let dentistry be a lonely, isolating grind. And every August, they gather in person at the Bulletproof Summit (Aug 7–9, 2026, The Phoenician, Scottsdale) to compare scoreboards and build the year ahead.

Your overhead number is not your destiny. It is a decision. Start making it on purpose.
