What Percentage of Revenue Should Go to Dental Staff Wages?

Two hygienists at the national median wage cost $196,200 a year in base pay, before a dollar of payroll tax, before benefits, and before you've paid a single assistant or front desk salary. The Bureau of Labor Statistics put the median annual wage for dental hygienists at $98,100 in May 2025. In a general practice collecting a little under a million dollars, that one line already consumes about 21 cents of every dollar collected, and most of the team hasn't been paid yet.

So here's our call, and plenty of consultants will fight us on it: the familiar 25%-of-collections staff wage benchmark is not a wage target for an independent practice under roughly $1.1 million in collections. It's a revenue test wearing a payroll costume. At today's wage levels you cannot negotiate, schedule, or discipline your way from 40% to 25% with five operatories and a normal general-dentistry case mix, and owners who try usually cut the exact hours that were generating the collections in the denominator. No practice ever cut its way to 25%.

The Only Government Number on Dental Payroll Says 38%

Before arguing about benchmarks, it helps to know what the public data actually shows. The Census Bureau's Service Annual Survey tracks payroll and revenue for the Offices of Dentists industry (NAICS 6212). Gross annual payroll for the industry came to $60,079 million in 2022, against industry revenue of $157,906 million. That's total employee payroll running at about 38% of revenue across the whole industry.

Two caveats, stated plainly because they matter. First, the two series don't cover an identical establishment base, so treat 38% as an order of magnitude rather than a decimal-perfect ratio. Second, and more important for how you read it: that payroll figure includes every W-2 on the books. Associate dentists are in there. So are employed dentists at group and corporate practices, who are a growing share of the industry. Sole-proprietor owner compensation generally isn't payroll, so it's mostly out.

That's the honest translation: the gap between the government's 38% and the advisory world's 25% is not evidence that someone is lying. It's doctor pay. Once you strip associate and employed-dentist wages out, you land in the twenties to low thirties, which is where the real argument lives.

25% Is an Advisory Benchmark, Not a Law of Nature

The widely circulated figure comes from accounting firms that benchmark their own dental clients. Dental CPA USA, for instance, puts non-doctor labor, meaning front desk, chairside, and assistants, at roughly 25% of collections with a normal range of 22% to 26%, based on the firm's client base rather than a published government sample.

That's useful information. It is not a physical constant, and it carries two hidden assumptions almost nobody states out loud. The first is a definitional one: does 25% mean base wages, or wages plus the employer side of payroll taxes, workers' comp, retirement match, and health contributions? Those are two very different numbers, and the load can add ten to fifteen cents on every wage dollar depending on what you offer. The second assumption is scale. A client base that averages well north of a million in collections per practice will produce a wage ratio that a $900,000 practice simply cannot reproduce with the same staffing model.

Our view: quoting a 25% target to an owner without first asking what they collect per operatory is advice that sounds rigorous and lands as noise.

Five Chairs, $946,000, and a 40% Wage Line

Let's build the practice and run it. We'll use the asking side of the market for a realistic shape, because that's where we have hard data. In The Dental Signal Practice Market Index, built from active dental broker listings, general practices listed for sale show median collections of $946,000 (n=644), a median of 5 operatories (n=754), and median collections per operatory of $200,000 (n=643). Those describe practices currently for sale, not all practices, but they describe the kind of practice most owners actually run: five chairs, a bit under a million, mid-market.

Staff it conservatively: two full-time hygienists, two assistants, two administrative seats. At the BLS median, the hygiene line is $196,200.

Assistants come cheaper. BLS puts the median annual wage for dental assistants at $48,070 in May 2025, and $48,000 specifically in offices of dentists, so two assistants run $96,000.

Say the two administrative seats cost $45,000 each in your market, for $90,000. Base wages for the six of them total $382,200.

Against $946,000 in collections, that's 40.4% in base wages alone.

Load it at a modest 12% for employer taxes and basic benefits and the true cost is $428,064, or 45.2% of collections.

Now run the benchmark backward. A 25% target on $946,000 gives you a wage budget of $236,500.

Two hygienists and one assistant cost $244,200, which is already over budget.

Read that again. At median wages, the 25% benchmark on a $946,000 general practice buys two hygienists and one assistant and nothing else. No second assistant. No front desk. The owner answers the phone, confirms the schedule, posts the payments, and seats patients. That isn't a lean practice, it's a solo practice wearing a five-chair building, and it's the arithmetic consequence of taking the benchmark literally at that revenue level.

Hold the same six people and ask what collections you'd need to hit 25%: $1,528,800.

That's the whole thesis in one number. The practices posting 22% to 26% non-doctor labor are not paying less per person. They're collecting $300,000 per chair instead of $189,200.

Cutting a $45,000 Seat Moves You From 40.4% to 37.2%

Here's the move we see owners make when the wage percentage spooks them: eliminate one administrative seat. Saves $45,000, which is 4.8 points of collections on paper.

Except that seat was doing something. Assume it was the person who worked recall and reactivation, and losing them costs one hygiene day a week. At the median $200,000 per operatory across about 46 working weeks, a hygiene chair runs roughly $4,348 a week, so one day is about $870.

Over a year that's $40,020 of collections gone.

Now the ratio: wages of $337,200 against collections of $905,980 is 37.2%.

You cut 12% of your payroll, took a real hit to patient flow, annoyed the remaining team, and moved the number 3.2 points. You're still 12 points from the benchmark. Meanwhile you traded $40,020 of collections, most of which was contribution margin on chairs you'd already paid for, to save $45,000 of wage. That's close to a wash in cash and a clear loss in capacity.

Now run it the other way. Fill the existing schedule with the same six people to $1,100,000 and the base wage line is 34.7%.

Same team. No raises withheld, nobody cut, five and a half points of improvement. We'd take that trade every time.

What Most Owners Get Wrong About the Wage Line

The specific mistake: comparing your wage percentage to a benchmark drawn from practices collecting 40% to 60% more per chair than you do, then solving the variance on the payroll side.

Two groups make it most often. First-time owners 18 to 36 months in, who've just met their accountant's benchmark sheet and want to look operationally sharp. And owners carrying fresh acquisition debt, where the lender's covenants make every overhead line feel urgent. Both groups cut the administrative seat first, because it's the one role with no obvious production number attached, which is precisely why its removal is invisible until the hygiene schedule starts leaking three months later.

A smaller but costly error: benchmarking wages month to month. Payroll runs on 26 or 27 biweekly cycles a year, so two or three months will carry three pay periods and spike 50% above trend. Owners react to the spike, make a staffing decision in the wrong month, and spend the next quarter rebuilding. Run wages as a rolling twelve-month figure against collections over the same twelve months, or don't run them at all.

The Two Ratios We'd Put on the Wall Instead

We'd stop tracking staff wages as a percentage of collections as a management tool. Keep it for your year-end review and for comparing yourself to the market, but it's a scoreboard, not a dial. You can't turn it directly.

Track these instead. First, collections per operatory, annualized. At $200,000 you're at the market median for practices that end up listed for sale, and at that level a 25% wage ratio is arithmetically out of reach. At $300,000 per chair the benchmark takes care of itself.

Second, our own rule for the hygiene department: a hygiene chair should collect at least three times the loaded wage of the hygienist sitting in it. One hygienist at the BLS median, loaded at 12%, costs $109,872.

Three times that is $329,616, which is well above the median $200,000 per operatory in the listings data.

That is not a comfortable finding, and we're not going to soften it. It means a meaningful share of hygiene chairs in mid-market practices are not carrying their own weight at today's wage levels, and the answer is schedule density, perio diagnosis, and adjunct services, not a smaller paycheck. Hygienists know what the market pays. Underpaying one is a 90-day problem that becomes a 12-month vacancy.

When 32% Is the Right Call

There are periods when we'd deliberately run wages at 30% to 33% of collections and sleep fine. You're opening a fifth or sixth operatory and hiring ahead of the schedule. You've just lost an associate and are shifting production toward hygiene and the owner's chair while you recruit. You're nine months into an acquisition and rebuilding a recall base the prior owner let rot. In each case the wage line leads the revenue line by two to four quarters by design.

The question isn't whether 32% is acceptable. It's whether you can name the date it becomes 28%, and what has to be true for that to happen. Owners who can answer that are investing. Owners who can't are drifting, and the difference looks identical on a P&L.

Three Numbers to Pull Before Friday

Pull your last twelve months of gross wages, excluding all doctor compensation, and divide by the same twelve months of collections, so you know your actual number instead of your accountant's category. Then divide those collections by your number of operatories and compare it to $200,000. If you're under $250,000 per chair, stop working the wage line entirely this quarter and work the schedule, the recall list, and your perio numbers instead.

What we're watching next: whether collections per operatory in our listings data keep pace with the next BLS wage update, because if hygienist wages rise another 5% while per-chair collections sit still, the mid-market staffing model breaks and the honest benchmark moves to 32%. What would change our mind is seeing $900,000 practices hold 26% with full hygiene schedules and no owner working the front desk, which would mean expanded-function assisting and hygiene-assisted scheduling solve this better than we currently think.

If you want to see where your own wage and overhead lines sit against the market before you make a staffing decision, run your own numbers through our free overhead calculator. It breaks out staff wages, doctor compensation, and facility costs separately, which is the only way to tell whether your problem is payroll or the top line. Every practice that runs it makes the benchmark sharper for the next owner who does.
