Practice economics
Overhead is one of the most quoted numbers in dentistry and one of the least consistently defined. This page explains what dental office overhead includes, what CORAL deliberately leaves out, how to calculate the percentage for a single month, and why overhead is not the same thing as profitability.
The definition
Dental practice overhead is what it costs to operate the practice, measured against the money the practice actually collected in the same period.
CORAL measures overhead against collections — money actually received during the month. Production describes work performed, and a practice cannot pay a supply invoice with treatment that has not yet been paid for. Using collections keeps both halves of the calculation in the same currency: money in, money out.
The dental practice overhead percentage is total operating expenses divided by collections. The percentage travels well in conversation, but it is best understood alongside other dental practice KPIs that measure output rather than cost. The total and individual categories are what an owner can actually act on; both should be read together.
CORAL does not publish an ideal, average or recommended overhead percentage, and does not define an industry benchmark. What matters is that your own practice is measured consistently, so the months can be compared with each other.
What is included
CORAL uses one fixed set of operating expense categories, so the same expense lands in the same place every month.
The first category is Team Labor Cost: the cost of the non-provider team. It covers wages and salaries, employer payroll taxes, benefits, paid time off, workers’ compensation, continuing education and uniforms, and any incentive amounts paid to team members. Dental practice labor cost is normally the largest single line in overhead, and dental payroll percentage — that figure divided by collections — is simply one part of the overhead percentage rather than a separate measure.
Provider compensation is kept apart from Team Labor Cost. Associate, specialist and other non-owner provider compensation is its own operating expense category, so the practice can see the cost of clinical providers separately from the cost of the team. Owner dentist and partner compensation is excluded from operating expenses altogether.
Associate / specialist / other non-owner provider compensation
Dental laboratory
Clinical / dental supplies
Occupancy — rent or lease, utilities, facility costs
Equipment & technology
Marketing
Business insurance
Professional & administrative expenses
Other operating expenses
Outsourced services need one deliberate decision. Employee-Only Team Labor Cost excludes them entirely. Adjusted Team Labor Cost adds declared, labor-replacing outsourced costs — an outside hygiene or billing arrangement that stands in for a role — without ever creating full-time-equivalent staff. Either basis is workable; the requirement is to enter the amount once, on one basis, so it is not counted twice.
What is excluded
An operating figure only stays comparable if items that are not costs of operating this month stay outside it.
Owner pay is a decision about what remains, not a cost of operating. Including it makes overhead depend on how the owner chooses to pay themselves, so the figure stops being comparable month to month.
Loan repayment reflects how the practice or its equipment was financed, not what it costs to run this month. CORAL shows debt service separately so an operating figure is not mixed with a financing one.
These are accounting allocations of an earlier purchase rather than money spent operating this month.
Buying equipment outright, or buying a practice, is an investment. Recurring lease, software and maintenance costs of using equipment do belong in overhead.
These follow from the result rather than producing it.
Overhead is measured against money actually collected, so amounts never received are not treated as an expense.
Owner compensation and debt service are not ignored — they are simply reported apart from the operating calculation, so an owner can see the operating picture and the ownership picture without the two being blended into one number.
The arithmetic
One calendar month, one set of definitions, three steps.
Step one
Take collections for the month — money actually received. If patient refunds have not already been deducted, subtract them once so they are not double counted.
Step two
Add the operating expense categories above for the same month. That sum is total operating expenses.
Step three
Divide total operating expenses by collections and multiply by 100. That is your operating overhead percentage. Collections minus total operating expenses is the Operating Remainder.
Illustrative example only
The figures below are invented for illustration. They are not an industry benchmark, an average, or a target CORAL recommends.
$82,000 ÷ $142,000 × 100 = 57.7%. $142,000 − $82,000 = $60,000. Owner compensation and debt service are not part of either figure.
The distinction that matters
These are two different questions, and confusing them is how a good-looking month turns into an uncomfortable surprise.
Operating overhead answers: how much of what we collected went to operating the practice? It is expressed as a percentage of collections, and it moves when either side of the division moves. A drop in collections raises overhead even when nothing about spending has changed.
Operating Remainder answers: how many dollars remained after the operating expenses included in the calculation? It is a dollar amount, with the same figure also shown as a percentage of collections.
Operating Remainder is deliberately not net profit, EBITDA, owner income or take-home pay. Owner compensation, owner distributions, debt principal and interest, depreciation, amortisation, capital purchases and personal income taxes all sit outside it. Those amounts still have to be paid from what remains, which is exactly why CORAL keeps them separate rather than folding them into a single number and calling it profit.
Dental office profitability, in the sense most owners mean it, is a conversation with an accountant working from a full profit-and-loss statement. What CORAL provides is the operating layer underneath that conversation: consistent categories, one month at a time, calculated the same way every time so the trend is real.
CORAL provides practice-management information and planning tools. It does not provide clinical, legal, tax, payroll or accounting advice.
Read it carefully
A single month is a snapshot of timing as much as of efficiency.
Collections arrive in a different month from the work that produced them. A month with strong collections and ordinary expenses looks efficient; the following month can look poor for the same underlying practice.
An annual insurance premium, a large supply order or a marketing campaign paid in one month lands entirely in that month's overhead. Nothing is wrong with the arithmetic — the month simply is not typical.
If collections are counted when money arrives, expenses should be counted the same way. Mixing the two produces a percentage that describes neither.
Dental practice labor cost moves with hours, overtime, new hires and partial months. A single month rarely shows whether a payroll change has settled.
The practical response is not to distrust the number but to calculate it the same way each month and read several months together. A consistent method is worth more than a single precise month.
What to do with the number
An overhead percentage describes a result. Changing it means changing the systems that produced it.
Overhead is produced by scheduling, treatment conversion, collections follow-up and how the team is structured. The dental practice management guide connects those operating responsibilities, while the free Reef Health diagnostic gives a structured read on those systems, which is usually where an overhead figure starts to make sense.
If team compensation is the part you are examining, CORAL Team Bonus System connects what is shared with the practice’s own monthly figures and its own profitability requirement. The guide to dental practice bonus systems compares the common models first, and the free dental bonus calculator estimates a bonus pool from collections and team compensation.
To calculate overhead itself, the dental practice profitability calculator is the tool for it. Overhead is only one figure among several; collection rate, team labor share and production per day each answer a different question. Money already earned but not yet received is a separate question, covered in our guide to dental accounts receivable. Related: CORAL pricing and Ask CORAL AI practice guidance.
Questions owners ask
Dental practice overhead is the cost of operating the practice, expressed against the money the practice collected in the same period. In CORAL, overhead includes non-provider Team Labor Cost, associate or specialist compensation, dental laboratory, clinical supplies, occupancy, equipment and technology, marketing, business insurance, professional and administrative expenses, and other operating expenses. Owner compensation and debt are handled separately.
Add the operating expenses for one calendar month, then divide that total by the collections for the same month and multiply by 100. That percentage is your operating overhead. CORAL's free dental practice profitability calculator performs the arithmetic from your own figures.
CORAL does not publish an ideal, average or recommended overhead percentage, and treats any single figure presented as a universal standard with caution. Overhead depends on insurance mix, whether associates are employed, whether the building is owned or leased, how much is outsourced and the stage of the practice. The useful comparison is your own practice over several months, calculated the same way each time.
Yes. Non-provider team wages, employer taxes, benefits, paid time off, workers' compensation and related team costs form Team Labor Cost, which is an operating expense. Dental payroll percentage is simply that figure divided by collections, and it is one component of overhead rather than a separate measure.
It remains provider compensation and is never reclassified as Team Labor Cost. For an operating overhead figure it is included as its own expense category, so the practice can see provider cost and team cost separately.
Not in CORAL's operating overhead. Owner pay and distributions are a decision about what remains after operating the practice. They can be shown separately in a reconciliation so the picture is complete without distorting the operating figure.
CORAL distinguishes Employee-Only Team Labor Cost, which excludes outsourced services, from Adjusted Team Labor Cost, which adds declared labor-replacing outsourced costs. Outsourced services never create full-time-equivalent staff. Whichever basis you use, enter the amount once so it is not counted twice.
Overhead measures operating expenses relative to collections. What remains after those same operating expenses is what CORAL calls Operating Remainder. It is not net profit, EBITDA, owner income or take-home pay, because owner compensation, debt, taxes, depreciation and capital purchases sit outside the operating calculation.
Monthly, using the same definitions and the same period each time, then read the months together. One month answers a narrower question than most owners expect it to.
Yes. The free dental practice profitability calculator produces total operating expenses, operating overhead percentage and Operating Remainder for one month, with optional separate lines for owner compensation and debt service. Nothing is stored and no sign-in is required.
CORAL publishes no overhead, payroll or profit-margin benchmark and makes no income guarantees. Figures on this page are illustrative. Financial, tax and payroll decisions should be reviewed with your accountant, bookkeeper, payroll professional or other appropriate adviser.
