Key takeaways
- Use collections and expenses from the same period and accounting convention.
- This tool excludes owner compensation, acquisition debt, and income tax by design.
- A low overhead percentage can conceal missing staff or deferred maintenance.
How is overhead defined in this calculator?
Operating overhead here is non-owner staff cost plus occupancy plus other operating costs. The percentage is that sum divided by collections, multiplied by 100. Because owner compensation is excluded, the remainder is not a pure investment return. It must still support the owner's work and other obligations.
Report definitions differ. If a source includes dentist compensation and this model excludes it, the percentages are not comparable. Write down the definition whenever you share the result with an advisor or buyer.
What belongs in each category?
| Field | Example components | Reconciliation question |
|---|---|---|
| Non-owner staff | Wages, employer taxes, benefits and required non-owner clinical labor | Are all necessary positions included? |
| Occupancy | Rent, agreed facility charges and recurring premises costs | Does the amount reflect the buyer's lease? |
| Other operating costs | Supplies, labs, insurance, software, utilities and recurring services | Are necessary recurring costs being excluded? |
Avoid counting the same cost twice. If utilities sit inside your occupancy budget, exclude them from the other-cost field. If an associate provides clinical labor, include that required operating cost even though the owner dentist's compensation is excluded.
What does the illustrative scenario show?
The sample uses $1,000,000 of collections, $300,000 of staff costs, $80,000 of occupancy and $270,000 of other costs. The sum is $650,000, or 65% overhead under this particular definition. The $350,000 remainder is before owner pay, acquisition debt, taxes and additional capital or reserve needs. These inputs are invented for instruction and are not an industry benchmark.
How should you compare practices or periods?
Reclassify costs consistently and confirm the period. A practice with a vacant hygiene position may report temporarily low payroll while losing future capacity. A seller who owns the building may record rent that will change after closing. Either situation can make a historical ratio misleading.
ADA practice research provides national economic context, but national averages do not establish an appropriate target for a specific practice. Use the source population and expense definition before making a comparison. (Source: ADA HPI: Dental practice research.)
What if overhead exceeds collections?
The model permits a percentage above 100 and a negative remainder. That is a useful warning about the entered scenario, not a software error. Check for mismatched periods or double counting, then evaluate whether the operating model is sustainable. Reducing a cost that is necessary to generate revenue may make the problem worse.
Bring a categorized P&L and the provider schedule to the next review. Identify the costs that will recur under the buyer's plan. Then test the cash left after all required payments.
How do you use the ratio in a purchase review?
Begin with a consistent period and a written expense definition. Compare the same categories across years before interpreting a trend. Check whether both years treat owner pay the same way. A change in that treatment can move the ratio even when the way the practice works has not changed.
Investigate the dollars behind a movement. Lower staff expense can result from a vacant position, fewer hours, a different provider model or a genuine efficiency improvement. Those explanations have different implications for patient capacity and the buyer's budget. Do not assume the lowest ratio is the most sustainable operating plan.
| Review question | Evidence to gather |
|---|---|
| Are categories consistent? | P&L accounts and a written mapping of included expenses |
| Are all needed roles funded? | Payroll detail, schedules, vacancies and proposed coverage |
| Will occupancy cost change? | Lease and agreed post-sale terms |
| Is a low cost temporary? | Ledger detail and the explanation for nonrecurring changes |
For a buyer scenario, replace historical costs only when you have a supported reason. If the seller owns the building and the buyer will pay a new rent, enter that rent in the proposed operating model. If a staffing vacancy must be filled, include the expected total employer cost with its supporting assumption.
Finally, carry the remaining cash into the owner-income calculator. Acquisition debt, capital funding and personal tax obligations do not disappear because an overhead percentage looks attractive. Keep past results separate from the buyer's budget. Label each proposed change and the evidence behind it.
How do you check a cost classification?
Choose one expense and trace it from the books into the model. For example, decide whether utilities belong in occupancy or in other costs. Use that choice for both periods. The total should stay the same when a cost moves between those fields. If it changes, a cost may have been omitted or counted twice.
Ask the CPA to check the boundary between cash costs and noncash entries. This model does not convert the books for you. Keep a note of each adjustment, its reason and the source document. Another reader should be able to rebuild the total without guessing where an expense went.
Frequently asked questions
Is the remainder the owner’s take-home income?
No. Owner compensation, acquisition debt, income tax, capital needs and reserves must still be addressed.
Should associate dentist compensation be included?
Yes, if it is a required non-owner operating cost. This model excludes owner compensation, not all clinical labor.
Is 65% the right overhead for my practice?
The sample 65% is an illustrative arithmetic result. It is not a target or a verified industry benchmark.
Can overhead be above 100%?
Yes. Entered operating costs can exceed collections. Reconcile the inputs and examine the cause before relying on the result.
