Reading Your Overhead: When 65% Is Healthy and 70% Is a Fire

There's a number on your profit and loss statement that decides, more than any other, how much you take home, and most owners couldn't tell you what it was last month within ten points. It isn't production. It isn't collections. It's overhead: the share of every dollar you collect that gets consumed running the practice before a cent reaches you.

Two practices can collect the same dollars and one owner takes home twice what the other does. The difference is almost never the top line. It's overhead. A practice running at 60% keeps forty cents on the dollar; a practice at 72% keeps twenty eight, and that's before the loan payment and the tax bill. Same chairs, same schedule, same city, and one of them is quietly going broke while looking busy.

This isn't a cost cutting lecture. Overhead isn't something to minimize at all costs; a practice starved of marketing, technology, and a good team produces less, not more. It's something to read. The goal is to know your number, understand what each piece is telling you, and recognize the difference between a healthy 65% and a 70% that should have your full attention. Get that literacy and the fixes become obvious. Skip it and you work harder every year while your take home flatlines.

What overhead actually measures

Overhead is the percentage of your collections eaten by operating expenses. Collect $1,000,000 in a year and spend $620,000 keeping the doors open, and your overhead is 62%. The remaining 38% is your operating profit, the pool the owner dentist's pay, debt service, and reinvestment all come out of.

Two definitions matter before you read your own number, because they're easy to confuse:

• Overhead is calculated on collections, not production. Production is what you billed; collections are what you banked. Produce a fortune and collect poorly, and your overhead looks misleadingly low against production and brutal against collections. Always read it against the money that hit the account.
• Owner compensation usually sits below the overhead line. In most practice P&Ls, what the dentist owner pays themselves is treated as profit, not overhead. That's the convention, and the right one: it lets you compare operating efficiency to other practices without your personal pay distorting the picture. Fold owner pay into overhead and every benchmark in this article stops meaning anything.

Get those two straight and the headline number becomes honest. Then the real work begins: reading the pieces.

The healthy range, and the line where it becomes a fire

Industry benchmarks are remarkably consistent here. A well run general practice typically runs overhead in the 55% to 65% range. That band leaves roughly 35% to 45% as operating profit, which lines up cleanly with the profit margins Overjet documents for the industry, typically landing in the 30% to 40% range once everything is accounted for. Healthy overhead and a healthy margin are the same fact described from two directions.

The danger zone starts where the cushion disappears. As NetSuite's breakdown of dental office overhead lays out, the further past 65% you climb, the thinner the slice left for the owner, and sustained overhead north of 70% is an emergency, not a rough patch. At 72%, you're keeping twenty eight cents per dollar to cover your own pay, your debt, your taxes, and any reinvestment in the practice. One slow month, one equipment failure, one staffing surprise, and you're funding the practice out of your savings.

Overhead doesn't announce itself. It creeps a point or two a year (a raise here, a new subscription there, a slower collection cycle) until one day you're producing more than ever and taking home less, and you can't say exactly when it happened.

Here's the distinction that matters most, though: 70% is not automatically a fire. A practice in heavy growth mode (onboarding a second associate, building out two new operatories, ramping marketing ahead of the demand it's about to create) can sit at 70% on purpose, temporarily, with a clear path back to the 60s. Overhead is only an emergency when it's high and stuck and unexplained. The number tells you to look. What you find in the components tells you whether to act.

The components, and how to read each one

The headline percentage is useless until you split it apart. A 64% practice with a bloated facility line and a lean team is a completely different problem from a 64% practice with a healthy facility and a payroll that's outrun its production. Here's the standard breakdown: the typical benchmark range for each as a share of collections, and what a number outside the band is usually telling you.

A few rules for reading the table:

• Add the bands and you get roughly 55% to 65%, which is exactly the healthy total. That's not a coincidence; it's where the benchmarks come from. If your total is healthy but a single line is way out of band, you have a specific problem masquerading as a fine practice.
• Read each line against your own model, not just the benchmark. A high prosthetics practice will run lab fees above the generic range and that's correct. The benchmark is a starting question, "why is this line where it is?", not a verdict.
• The trend beats the snapshot. A line that's stable at the high end of its band is fine. A line that's climbed three points in eighteen months is the story, even if it's still technically "in range."

Staff: the biggest line, and the one to read most carefully

Team compensation is almost always the largest single piece of overhead, commonly benchmarked in the 25% to 30% range. Because it's the biggest, owners panic about it first, and usually draw the wrong conclusion. The fix for high staff overhead is rarely "cut the team." It's "produce more per payroll dollar." If payroll is 33% of collections, the question isn't who do we let go; it's why is the team supporting less production than its cost implies? Often the answer is an unfilled schedule, weak case acceptance, or idle hygiene capacity. You fix high staff overhead at the top of the funnel, by filling the chairs the team can already serve, far more often than at the bottom by shrinking the team.

Facility: the line you can't fix this quarter

Occupancy costs (rent or mortgage, utilities, upkeep) should sit around 5% to 8% of collections. The trouble is that this line is mostly locked: you signed a lease, and you can't renegotiate it because your overhead drifted. That's why facility overhead is best treated as a denominator problem. If rent is fixed, the way to bring its percentage down is to raise the collections it's divided into. Grow production and you keep the same rent while the facility percentage falls on its own.

Supplies and lab: the lines that reward discipline

Supplies (5% to 7%) and lab (5% to 10%) are where operational discipline shows up fastest: they respond to vendor contracts, inventory controls, and reducing waste and remakes. They're also where small leaks add up: a few points of off contract supply pricing or a steady trickle of lab remakes won't sink you, but they quietly tax every case. Unlike facility, these move in a single quarter if you decide to manage them.

Marketing: the most misread line on the statement

Marketing typically runs 3% to 8% of collections, and it's the line owners misjudge most in both directions. Cut it too far and the new patient pipeline starves; overhead looks better for a quarter while production erodes underneath. Let it run without accountability and you're paying for spend that doesn't convert: a real cost with no patients to show for it. The right way to read marketing overhead is never the dollar amount in isolation; it's the cost relative to the booked patients it produces. Spend that turns into appointments isn't overhead in any meaningful sense; it's the engine. Spend that doesn't is pure leak. We'll come back to this, because it's where the biggest hidden fix lives.

The fixes, in priority order

Once you've read the components, the fixes sort themselves by leverage. In rough order of impact per effort:

1. Fill the schedule before you cut anything. Most overhead problems are denominator problems. Staff, facility, and equipment costs are largely fixed in the short run, so the most powerful move is to raise the collections they're divided into. Every line's percentage falls when production rises against fixed cost, which is why a growth problem and an overhead problem are usually the same problem.
2. Fix collections, not just production. Overhead is measured on what you bank. Tightening your collection cycle (reducing aging receivables, collecting at time of service, cleaning up insurance follow up) lowers your overhead percentage without touching a single expense, because the denominator grows.
3. Tighten the variable lines. Supplies, lab, and miscellaneous spend respond to contracts and controls within a quarter. Get supplies on contract, drive down remakes, audit the recurring charges nobody owns.
4. Make marketing accountable, not smaller. Don't cut the funnel; measure it. Reallocate from spend that doesn't convert to spend that books patients, so the line produces production instead of just consuming budget.
5. Attack vendor and tool sprawl. The one almost everyone misses, and the one that pays back twice. It deserves its own section.

The lever owners miss: vendor and tool sprawl

Here's the overhead leak that almost never gets named, because it doesn't sit on one line; it's smeared across the whole statement. Walk through a typical practice's recurring bills and you'll find a website vendor, a separate SEO company, an ad agency, a CRM or patient communication tool, an online scheduling app, a reviews platform, a reactivation service, a phone and reception system, and a fistful of point solutions that each solve one small thing. A dozen plus subscriptions and outside agencies, each with its own invoice, login, contract, and renewal you forgot to review.

The direct cost of all that is real, and it adds up fast, but it's not even the expensive part. The expensive part is the hidden overhead of running the stack: the staff hours spent stitching tools together, the data that doesn't flow from the scheduler to the CRM to the phone system, the agency status calls, the integrations that break, the four vendors who each blame the other three when something goes wrong. None of that shows up as a line item called "coordination," but it's paid for in the most expensive currency you have: your team's time and your own attention.

This is why consolidation is one of the highest leverage overhead moves available, and why it shows up nowhere in the standard benchmark tables. When one platform runs your website, SEO, advertising, CRM, and reception, the front of house and growth functions otherwise scattered across five to ten separate vendors, you don't just collapse five bills into one. You delete the coordination tax entirely. The data flows because it's one system. One login, one renewal, one point of accountability. The hours your front desk spent reconciling tools go back into running the practice.

It also fixes the marketing line specifically. When website, SEO, and advertising live in separate silos run by separate vendors, nobody owns the whole journey from a search to a booked appointment, and spend leaks at every handoff. Pull those onto one platform and the marketing dollar becomes accountable end to end. That's the job of the Campaign Strategy agent: making every marketing dollar produce booked patients instead of bloating the marketing line, turning spend into production rather than overhead. On the Patientfy platform that agent doesn't operate in isolation; it works alongside the website, SEO, CRM, and reception agents as one system, which is exactly what removes the coordination overhead the multi vendor stack quietly charges you every month.

The math compounds. Cut the direct subscription cost and recover the staff time spent managing the stack, and you've moved two lines at once (administrative spend and effective payroll productivity) from a single decision. For a practice stuck in the high 60s, consolidation is often the difference between a fire and a healthy 62%.

How to run the read on your own practice

You don't need a consultant for the first pass, just your last twelve months of collections, your P&L, and an afternoon:

1. Calculate the headline number. Total operating expenses (excluding owner compensation and debt service) divided by total collections. Note it, and note last year's so you have a trend.
2. Split it into the components above. Staff, facility, supplies, lab, marketing, admin, each as a percentage of collections, laid next to its benchmark band.
3. Flag every line outside its band, and every line that moved. A line that's high but stable for your model may be fine. A line that's climbing is the story regardless of where it sits.
4. Read marketing against patients, not dollars. What did the marketing line cost, and how many booked new patients did it produce? If you can't answer that, there's your first leak.
5. Count your vendors and subscriptions. Literally list them. The length of that list is usually a surprise, and almost always the fastest overhead win you have.

That read turns "my overhead feels high" (an anxious, shapeless worry) into "staff is two points hot because the hygiene schedule has holes, supplies are off contract, and we're paying nine separate vendors for things one platform could run." That's a list you can act on, calmly, with numbers.

The takeaway

Overhead is the quietest number on your statement and the one that decides the most. It doesn't spike; it drifts, a point a year, a subscription at a time, until you're working harder than ever and keeping less, with no single moment to blame.

So know it. A healthy general practice lives in the 55% to 65% band, leaving the 30% to 40% margin the industry considers healthy; 70% and climbing is a fire that deserves your attention now, not next quarter. Read it by its components, because the headline number hides which piece is actually broken. Fix it by raising the denominator before cutting anything, by making marketing accountable instead of smaller, and by attacking the vendor sprawl that taxes you twice (once in subscriptions and again in the hours spent holding a dozen tools together). The practices that take home the most aren't the ones that collect the most. They're the ones that read their overhead clearly and kept the most of every dollar they earned.
