Dental Practice Overhead Benchmarks in Indiana (2026)

A general practice collecting $950,000 a year in Indiana gave up roughly $16,000 of annual owner income over the last five years without losing a patient, without cutting a fee, and without a single line item anyone would flag in a P&L review. That loss came entirely from the spread between how fast revenue grows and how fast costs grow, and in Indiana that spread has a specific name: wages.

Here's our thesis, and plenty of owners will push back on it. The 62% national median overhead is the wrong target for most Indiana practices, and every hour spent chasing it through supply catalogs and lab shopping is an hour stolen from the two decisions that actually move the number: what you pay to keep a team in a labor-short state, and how much production you run through the operatories you already pay rent on. Overhead is a fraction, and most owners spend an entire career fighting the numerator.

Indiana's Wage Floor Is Set by Scarcity, Not by Your P&L

The Bureau of Labor Statistics puts 2,550 general dentists in Indiana at a mean annual wage of $200,000, or $96.15 an hour, in its May 2023 state occupational wage estimates. That is the number an associate candidate's recruiter quotes, and it is the number your hygienists' market moves in sympathy with, because the same shortage drives both.

How short is short? Indiana carries 133 designated Dental Care Health Professional Shortage Areas covering 1,127,678 people, with just 27.84% of dental need met and 207 additional practitioners required to clear the designations, according to HRSA data compiled by KFF as of December 31, 2025. A state that needs 207 more practitioners to reach baseline adequacy is not a state where you win a hiring negotiation by holding firm. It is a state where the market sets your payroll line and tells you afterward.

That matters because payroll is the largest single block of overhead. Benchmarks attributed to ADA Health Policy Institute data by Dental Practice Insider put staff payroll at 25 to 28% of collections, dental supplies at 5 to 7%, lab fees at 7 to 10%, occupancy at 5 to 8%, and equipment and depreciation at 3 to 5%, with total overhead landing between 58 and 65%. Staff payroll is bigger than supplies, lab, and equipment combined. A three-point move in payroll is worth more than eliminating your entire supply spend.

Drift vs. Erosion: Which One Is Eating Your Margin

We use Drift vs. Erosion to sort adverse cost trends into two buckets, because the response to each is completely different. Drift is small, steady, and recoverable: your supply spend creeping from 5.8% to 6.3% because nobody's been watching the ordering, your lab bill nudging up as case mix shifts. You manage drift operationally. You fix it with attention, not with a new business model.

Erosion is structural and compounding. It doesn't reverse when you pay attention harder. Indiana's wage environment is erosion. So is a PPO fee schedule that hasn't moved in four years while your costs moved 4.9%. The ADA Health Policy Institute reports average net income for general-practice dentists at $215,320 in 2025, and over the trailing five years practice revenues rose only 1.4% while practice expenses rose 4.9%. That gap is not noise. It is the shape of the decade.

The expensive mistake is treating erosion as drift. An owner who responds to a permanent 3-point payroll reset by launching a supply audit has misclassified the problem, and will spend a year discovering that they cannot save their way out of a structural repricing.

What Most Owners Get Wrong: Calling a Wage Reset a Bad Quarter

The specific mistake, and it clusters hard among solo general practices in the $700,000 to $1.1 million collections band, is building a 2026 staffing model on 2019 wage assumptions and then treating the gap as an execution failure. These owners typically hit 70% overhead, conclude their team is inefficient or their spending is loose, and start a tightening campaign: fewer temps, slower hiring, tighter supply ordering, no raises this cycle.

What follows is predictable. The hygienist with the best retention numbers takes a job twenty minutes away for $4 an hour more. Hygiene days go uncovered. Recall production drops. Six months later, collections are down 8% and overhead is worse than when the tightening started, because the fixed lines never moved and the denominator shrank.

Our view: for practices under $1.5 million, overhead percentage is a diagnostic, not a target. Managing to the percentage instead of to the dollars is how owners end up cutting the only inputs that were producing.

A $950,000 Practice, Line by Line

Take an Indiana general practice collecting $950,000 with five operatories. Apply the mid-range category benchmarks: staff payroll at 27% is $256,500. Supplies at 6% is $57,000. Lab at 8% is $76,000. Occupancy at 6% is $57,000. Equipment and depreciation at 4% is $38,000. Those five lines total $484,500, or 51% of collections.

Add the rest (marketing, malpractice and business insurance, billing and software, merchant fees, professional fees, continuing education) at a combined 12%, or $114,000, and total overhead is $598,500, 63% of collections. Owner earnings before owner compensation: $351,500.

Now run the ADA HPI trend across it. Expenses up 4.9% adds $29,327. Revenue up 1.4% adds $13,300. Net change to the owner: minus $16,027 a year. Overhead ratio moves from 63.0% to 65.2%. Nobody made a bad decision. The practice just sat still.

Now the payroll reset. Move staff payroll from 25% to 28% of collections, which is exactly the span the ADA-attributed benchmarks describe, and you add $28,500 a year. Cutting supplies from 6% to 5% recovers $9,500. You've covered a third of it and you've made ordering harder for the whole team.

The Denominator Move Nobody Runs

Here's the other end of the fraction. Our Practice Market Index, built from dental practice broker listings (the asking side of the market, not a sample of all practices), shows a median of five operatories among listed practices (n=754) and median collections per operatory of $200,000, with the middle half between $146,875 and $268,708 (n=643). Median collections among listed practices run $957,588 (n=753), and among Indiana listings specifically, $931,000 with a middle half of $710,000 to $1,350,000 (n=35).

Five operatories at $200,000 each is $1,000,000. A five-operatory practice collecting $760,000 is running about $152,000 per chair, near the bottom of that middle half. Its rent doesn't care. That same $57,000 occupancy line is 7.5% of $760,000 instead of 6.0% of $950,000. Equipment at $38,000 goes from 4.0% to 5.0%. That's 2.5 points of overhead created by empty chairs, not by spending.

Run it the other way. Add one productive hygiene day a week at $1,800 in production and you add roughly $86,400 a year against a marginal cost of maybe $34,000 in hygiene wages, benefits, and supplies. Contribution: $52,400. That single move funds the $28,500 payroll reset almost twice over and drops overhead by about 1.7 points, because the fixed lines spread across a bigger base.

The Overjet breakdown by practice size makes the same point from a different angle: practices under $750,000 in collections run 70 to 80% overhead, $750,000 to $1.5 million run 60 to 70%, and above $1.5 million run below 60%, with a national median near 62%. That is not a gradient of managerial skill. It is a gradient of fixed-cost absorption. Overhead percentage is mostly a size statistic, and owners who read it as a report card on their discipline draw the wrong conclusion nearly every time.

What We'd Actually Do With $28,500 of New Payroll

We'd fund it out of the reimbursement side, not the expense side. If you have a PPO plan sitting at the bottom of your fee schedule with a table that hasn't moved since 2022, that's erosion and it deserves a renegotiation letter or a drop, not another year of patience. Dropping a plan that represents 8% of your production at a 42% write-off is usually margin-positive within two quarters once the chair time backfills, and if it doesn't backfill, you've learned something worth more than the plan was paying you.

We would not fund a permanent wage increase with a supply squeeze. It doesn't cover the number, it annoys the people you just gave a raise to, and it signals to a team in a shortage state that money is tight, which is the exact message that starts them checking listings. We'd also skip the equipment deferral. Pushing a chair replacement out two years to protect a 4% line while your payroll line moved 3 points is trading a capital decision for an operating problem.

What Would Change Our Call

Two things. If Indiana's shortage designations start closing (that 27.84% need-met figure moving materially, or the 207-practitioner gap narrowing), the wage pressure reclassifies from erosion back to drift and the whole calculus softens. And if we see collections per operatory among Indiana listings pulling away from the national median in either direction, it tells us something about whether in-state practices are absorbing fixed costs better or worse than the country, which would change how hard we push the denominator argument. We're watching both.

Three Things to Do Before Your Next Payroll Run

Pull your last twelve months and calculate collections per operatory, not just total overhead: if you're under $150,000 per chair, your overhead problem is a capacity problem and no expense cut will fix it. Sort every rising cost line into drift or erosion and write the classification down, because the ones you label erosion need a renegotiation or an exit date, not a watchlist. Then price your lowest PPO plan honestly, write-off percentage against chair time consumed, and decide this month whether it stays.

If you want to see where your own numbers land against the 58 to 65% band and against Indiana's cost structure specifically, run your own numbers through our free overhead benchmark calculator. It breaks your practice down by payroll, supplies, lab, occupancy, and equipment, and shows you which lines are actually out of range and which ones are just the size of your practice talking.
