Your Overhead Is 62%. Industry Average Is 58%. Here's Why You're Bleeding Money.

Four points of overhead on a $950,000 practice is $38,000 a year. That is a hygienist's wages, a new chair and a vacation, and most owners who find that gap on a benchmark chart go hunting for it in the supply closet, which is close to the worst place to look.

Here is our position, and plenty of owners will hate it: if your overhead has drifted from 58% to 62% while your production stayed flat, you do not have a cost problem. You have a pricing and capacity problem wearing a cost problem's clothes, and the cost-cutting playbook will get you about two thirds of the way there while making your practice worse to work in. You can't cut your way out of a reimbursement problem. You can only cut your way down to a smaller version of it.

The 58% You're Comparing To Isn't Measuring What Your 62% Measures

Start with what most owners get wrong, because it poisons everything downstream. The overhead number you pulled off a slide, a podcast or a Facebook group is almost never computed on the same base as the number your accountant handed you.

The ADA's own figures are the cleanest reference point available. In the 2026 Survey of Dental Practice, median expenses for general-practice owners, excluding shareholder and owner salary, were $509,720 against median gross billings of $893,510. That is a 57.0% expense-to-billings ratio. Two things about that number matter more than the number itself: it excludes owner compensation, and the denominator is gross billings, not collections.

Your P&L almost certainly does neither. It has your continuing education trip, your auto, your retirement contribution, your spouse on payroll at $38,000, and it runs off collections. If you write off 32% of billings to PPO fee schedules, your overhead-on-billings and your overhead-on-collections are two different universes, and only one of them pays your mortgage.

The consulting benchmarks are on a third base again. Levin Group's management target is 60% of collections for total general-practice overhead, split into employee costs at 28% or less (with a goal of 24% to 26%), supplies at 6%, lab at 8%, facility and equipment around 10%, and other business costs at 11%. Meanwhile the firm's own survey data put median actual overhead for general practices at 75%, against a 59% recommended target. A 15-point spread between what the same firm recommends and what it measures is not a measurement error. It is a definitional one.

Our view: the specific mistake is comparing a ratio you did not define to a ratio someone else did not define either, then acting on the difference. The owners who make it are the diligent ones, the ones who actually read the benchmarks. The ones who never look at overhead at all make a different and worse mistake, but at least they don't fire a chairside assistant over a basis mismatch.

Is It Drift or Is It Erosion?

Before you touch a line item, classify the trend. We use Drift vs. Erosion for exactly this. Drift is small, steady and recoverable: a supply account that crept up because nobody renegotiated, a lab bill that grew because case mix changed, two extra administrative hours a week that nobody authorized. You manage drift operationally and it goes back where it came from. Erosion is structural and compounding: the cost base is rising faster than the revenue base can follow, and no amount of operational discipline reverses it. Erosion requires renegotiation, repricing or exit.

The macro data says most of the current four-point move is erosion. The ADA's State of the U.S. Dental Economy, Q3 2025 Update puts the dental office expense index at 144 by August 2025, against a January 2015 base of 100, including a 5% jump in equipment and supply prices in the first eight months of 2025 alone. Over the same stretch, provider reimbursement indexes reached only 129 to 131 and overall inflation 138. Your costs are running ahead of both the general price level and the money insurers are willing to send you. The ADA calls it a fiscal squeeze. We'd call it a repricing signal.

The practice-level data agrees. In the the Practice Market Index, our dataset of 925 broker listings, median collections are $946,000, with five operatories the median configuration (n=754). Those are practices on the market, the asking side, not a cross-section of every practice in the country, but $950,000 across five chairs is a recognizable shape.

At 62%, expenses are $589,000 and owner income is $361,000.

At 58%, expenses are $551,000 and owner income is $399,000. The gap is $38,000.

That tracks the rule of thumb in the Levin survey data, where each one-point cut in overhead adds roughly $10,000 to owner take-home on a $1M-production practice.

Route A: cut $38,000. Work the line items against the published targets. Supplies at 6% of collections is $57,000, and a hard 10% reduction through consolidating vendors and killing duplicate stock gets you $5,700.

Lab at 8% is $76,000, and an aggressive 8% reduction through renegotiation or moving single units in-house gets $6,080.

Employee costs at 28% are $266,000, and pulling two full points out, which in practice means roughly 15 hours a week of someone's job, gets $19,000.

Total: $30,780. You are $7,220 short, you have touched every variable you control, and you have made the schedule harder to run.

Route B: hold expenses and add collections. New production is not free, so charge it honestly: lab at 8% plus supplies at 6% means 14% of every incremental dollar goes straight back out. Solving for the collections increase that lands the ratio at 58% gives you about $86,364 in added collections.

Across five chairs that is $17,273 per operatory per year, or about $360 per chair per week across 48 working weeks. One additional crown per chair per month gets you most of the way there.

Here is the part that should change your plan. That $86,364 carries $12,091 of variable cost, leaving $74,273 of contribution. Route A, executed perfectly, delivered $30,780. Route B delivers roughly 2.4 times as much money, and the 58% ratio shows up as a by-product rather than a target.

Your Four Points Are Probably in the Walls

Facility and equipment is the line item nobody can cut and everybody ignores. At the 10% benchmark, that is $95,000 a year on a $950,000 practice, and it is fixed against your operatory count, not your production.

In the Practice Market Index, median collections per operatory among listed practices run $200,000, with the middle half between $146,875 and $268,708 (n=643). Our five-chair example at $950,000 is doing $190,000 per chair, which is normal. The same $950,000 in a seven-chair build is $135,714 per chair, and that practice is structurally at 62% or worse no matter how well it buys gloves.

This is also where the ADA's quartile data earns its keep. At the third quartile, owner expenses of $747,130 against gross billings of $1,198,710 work out to 62.3%. Higher-cost practices are not generally smaller practices. They are bigger ones carrying more fixed capacity than their schedule fills. If that is you, the answer is hours and fee schedules, not vendors.

What Would Change Our Mind

We're watching the spread between the ADA's dental office expense index and its provider reimbursement indexes, currently 144 against 129 to 131. If reimbursement starts closing that gap in the 2026 fee cycles, the erosion call softens and conventional cost management becomes the right first move again. We're also tracking per-operatory collections in the listing data quarter over quarter, because if that median starts falling while operatory counts hold, the industry's problem is capacity use and the whole overhead conversation needs reframing. Until one of those turns, we'd stop benchmarking the ratio and start repricing the work.

Do These Four Things Before the 15th

Recompute your overhead twice, once on collections including your own compensation and once excluding it, and write both numbers at the top of the page so you never again compare the wrong one to someone else's. Divide your trailing twelve months of collections by your operatory count and see whether you are above or below $200,000 per chair. Pull your three largest PPO contracts and check the last date any fee schedule actually moved. Then pick one: raise fees on your top ten procedures, drop the worst contract, or fill the chair that sits empty two days a week.

If you want to see where your own four points actually sit, our overhead benchmarking tool breaks your costs into the same categories used above and compares them against published targets on a consistent base, so you are measuring the same thing the benchmark measures. It takes about ten minutes with a P&L in front of you. Run your own numbers and find out whether you are managing drift or financing erosion.
