Dental Practice Overhead Benchmarks (2026): Reading Your P&L Like a CFO

Your accountant sends over the year-end P&L. Total expenses: 82% of collections. You have heard that dental practice overhead should run somewhere around 60%, so you do the math twice, feel your stomach drop, and start wondering which hygienist you can afford to lose. Or the opposite happens: the number looks fine, you file the report in a drawer, and a slow leak in staff costs keeps compounding for another year because nobody broke the total apart.

The short version: a dental practice overhead benchmark is only useful if you measure the same thing the benchmark measures. That means three adjustments before you compare anything: divide by collections, not production; pull the owner-dentist’s own pay and perks out of the expense total; and set loan interest and depreciation aside as financing, not operations. Once your P&L is recast that way, the published rules of thumb (roughly 58–67% total operating overhead, with staff the biggest line at roughly a quarter of collections) become a real diagnostic tool. Then the question stops being “is my overhead too high?” and becomes “which line moved, and what is each point worth?”

Why most dental practice overhead numbers are wrong before you start

There is no single, official definition of dental overhead. Consultants, dental CPAs and software vendors each draw the line a little differently. The number you get from your own books depends almost entirely on three choices, and most practice owners have never been told they are choices at all.

Choice 1: the denominator

Overhead is a percentage of collections — the cash that actually arrived. Not gross production, and not net production after PPO write-offs. If you divide by gross production, a PPO-heavy practice will look lean on paper while the bank account says otherwise. Production and collections are different numbers for a reason, and a benchmark built on one cannot be compared to a ratio built on the other.

Choice 2: the owner’s own compensation

Your W-2 salary, your distributions, and the personal car, phone and CE trip that run through the practice are not overhead. They are what the practice pays you for being the dentist and the owner. Leave them in, and a perfectly healthy practice looks like it is running at 80%+. Most benchmark ranges exclude owner-doctor compensation entirely. If you are structured as an S corporation, your reasonable salary is still owner compensation for this purpose — the tax treatment is a separate question, covered in our guide to Rhode Island LLC vs. S corp.

Associate dentists are different. An associate’s pay is a real operating cost and belongs in overhead, usually tracked as its own line so it does not muddy the staff ratio.

Choice 3: financing costs

Loan interest and depreciation tell you how you paid for the practice and the equipment, not how efficiently you run it. Set these aside when benchmarking, then look at them separately when you look at cash. (Bonus depreciation also gets treated differently by Rhode Island than by the IRS, which is one more reason not to let the depreciation line drive operating decisions.)

Takeaway: before you compare yourself to anyone, recast the P&L. Collections on top, owner compensation and financing costs below the line, everything else in between.

What the published ranges actually say (and where they disagree)

An honest caveat first. The category benchmarks circulating online are compiled industry ranges — assembled by consultants, software companies and dental publishers from survey data, CPA client files and each other. Several cite the American Dental Association secondhand, and they do not agree line for line. Treat everything below as a rule of thumb, and treat the spread between sources as information in itself.

Pulling three widely cited 2026 compilations together, here is where the ranges land as a percentage of collections:

• Staff wages, payroll taxes and benefits (excluding the owner): roughly 24–30%.
• Clinical supplies: roughly 5–8%.
• Lab fees: roughly 6–10%. One compilation lumps lab and supplies together at 6–8% combined, which is a meaningful disagreement.
• Facility (rent or mortgage, utilities): roughly 5–10%.
• Marketing: roughly 2–5%, with at least one source arguing growing practices should spend more.
• Total operating overhead: most compilations center somewhere around 60–65%, with a full spread of about 58–67%. One source flags anything above 70% as a serious problem, and anything below 55% as a possible sign of underinvestment.

The sources do agree on two things: overhead percentage tends to fall as collections rise, because rent, the front desk and the software stack do not double when revenue does; and specialty practices run different numbers entirely. Orthodontics carries almost no lab cost. Oral surgery carries more facility and staffing cost. Those ranges are built for general dentistry.

Why this matters more in 2026 than it did five years ago

The pressure on these ratios is real and measurable. According to the ADA Health Policy Institute’s Survey of Dental Practice, dental practice revenues rose 1.4% over a five-year period while expenses rose 4.9%. The 2025 Dental Economics–Levin Group Annual Practice Survey found that 58% of practices reported higher overhead in 2025 than in 2024, with an average increase of 4.5% — while average production per doctor was, in the survey’s own words, statistically flat. Rising overhead and declining insurance reimbursements were the two most-cited challenges, each named by more than half of respondents.

Flat production plus rising costs is exactly the environment where an annual glance at total overhead misses the problem. The total moves a point or two. A single line underneath it can move much more.

Reading the P&L like a CFO: a worked example

Here is an illustrative composite — not a real client — built to show the method. A general dental practice in East Providence, one owner-dentist, two hygienists, PPO-heavy, $1,250,000 in annual collections. The bookkeeper’s P&L shows total expenses of $1,026,000, or 82.1% of collections. The owner reads that as “my overhead is 82%” and assumes the practice is in trouble.

Recast, it looks like this:

The practice is not running at 82%. It is running at 62%, which is squarely normal. But “normal” is not the same as “fine,” and the recast is where the real finding shows up.

The line that moved

Last year this practice collected $1,235,000 and spent $310,000 on staff — 25.1%. This year collections rose about 1.2% to $1,250,000, while staff cost rose about 11.3% to $345,000. A retention raise, an assistant hired ahead of growth, a benefits renewal — each reasonable on its own.

Together, they moved the staff ratio 2.5 points. On $1.25 million of collections, that is roughly $31,000 a year of owner income that quietly moved into payroll — and total overhead still looks “in range,” so nobody noticed.

The simple formula that makes this visible

Every practice owner should know one number cold:

Value of one overhead point = annual collections × 1%

At $1,250,000, one point is $12,500 a year. At $800,000, it is $8,000. At $2 million, it is $20,000. Every percentage on your P&L now translates into dollars. “Staff went from 25% to 27.6%” is abstract. “Staff is costing me an extra $31,000 a year compared to last year” gets a conversation started.

What to do with each line

Benchmarks start a conversation; they do not end it. Here is how a CFO reads each of the big lines once it is flagged.

Staff

Staff is the largest controllable cost and the one owners are most reluctant to touch, for good reason — a good team is hard to replace. The right response to a rising staff ratio is usually not a layoff. It is one of three things:

• Grow into the team. If you hired ahead of growth, the fix is filling the schedule, not emptying the chairs. That is a capacity and marketing question.
• Re-price the work. If fees have not moved while wages have, the ratio will keep creeping. Review fee-for-service fees annually and know which PPO plans are dragging your effective fee down.
• Check the loaded cost. Payroll taxes, benefits and paid time off can add a meaningful percentage on top of base wages. If you are benchmarking wages alone against a range that includes taxes and benefits, you will think you are lean when you are not.

Lab

A high lab percentage is not automatically a problem. A practice doing more crowns, implants and dentures will run higher lab costs than a practice doing mostly hygiene and fillings — and the revenue from those cases should more than cover it. The question is lab cost as a share of the fees on the cases that used the lab, not lab as a share of everything. If that ratio is rising, look at remakes, lab pricing and whether PPO fees on crown codes have fallen.

Facility

Rent is the most fixed cost you have. You cannot manage it month to month, but you can manage it at the lease renewal — and you can grow into it. A premium location near the top of the range is a fair trade if it drives new patients.

Marketing

Below-range marketing can be a sign of a practice that is full and does not need it — or a sign of a practice whose new-patient flow is slowly drying up. Check new patients per month over the last twelve months before deciding which.

Takeaway: never cut a line just because it is above a published range. Cut it, fix it or grow into it based on what is driving it.

Build a monthly dental practice overhead review in 30 minutes

Annual reviews catch problems a year late. A monthly review catches them while you can still act. Here is the routine we recommend for owners of practices in the $500K–$5M range:

• Get clean books first. If expenses are coded inconsistently month to month, ratios are noise. A bookkeeper who understands healthcare bookkeeping will code lab, supplies and associate pay to their own accounts. If you are behind, start with catch-up bookkeeping.
• Use a trailing three-month view. A single month is distorted by a big lab bill, a payroll with three pay dates, or an insurance check that landed late. Rolling three months smooths that out.
• Track five ratios, not twenty. Staff, lab, supplies, facility and total operating overhead — each against collections, each against the same period last year.
• Translate every change into dollars. Use the one-point formula above.
• Tie it to cash. Overhead lives on the P&L. Your ability to pay it lives in the bank account. A 13-week cash flow forecast is where you see whether next month’s payroll, lab bills and loan payment actually fit.

If your books are in QuickBooks, most of this can be built into a saved custom report — a QuickBooks advisor can set up the class and account structure so the ratios fall out automatically each month.

Where a CFO fits — and where a bookkeeper stops

Your bookkeeper records the P&L; your tax preparer minimizes the tax on it. Neither is paid to tell you that staff has drifted 2.5 points, or that your lab ratio is really a PPO fee problem, or that the associate you are about to hire needs a full schedule by month four to pay for herself. That interpretive layer is the job of a CFO.

Frequently asked questions

What is a normal overhead percentage for a dental practice?

Published rules of thumb for general dentistry cluster around 60–65% of collections, with a wider spread of roughly 58–67% across sources. Those ranges exclude the owner-dentist’s own compensation and generally assume you are dividing by collections, not production. Smaller practices tend to run higher; larger practices tend to run lower.

Should dental overhead be calculated on production or collections?

Collections. Production includes fees you will never collect because of PPO write-offs, adjustments and bad debt. Calculating overhead on production makes a practice look leaner than it really is.

Is the owner-dentist’s salary included in overhead?

No. For benchmarking, the owner’s salary, distributions and personal expenses run through the practice are owner compensation, not overhead. Associate dentists’ pay is different — it is a real operating cost and belongs in overhead.

What percentage of collections should dental staff wages be?

Compiled industry ranges put staff wages, payroll taxes and benefits (excluding the owner) at roughly 24–30% of collections. Sources disagree on the exact band, so the more useful test is your own trend: if your staff ratio is rising faster than collections, find out why.

How often should I review my dental practice overhead?

Monthly, using a trailing three-month average to smooth out timing noise. An annual review catches problems a year after they start. A monthly review tied to a cash flow forecast catches them while there is still time to act.

Bottom line

Dental practice overhead is not one number — it is five or six ratios, and the total can look perfectly healthy while one of them quietly costs you tens of thousands of dollars a year. Recast your P&L so you are comparing like with like, learn what one point of overhead is worth at your collections level, and review the lines monthly instead of the total annually. The published benchmarks are a starting point, not a verdict.
