The costs of a dental clinic: where the money goes (and what you don't see)
Between what you bill and what you take home there's a long list of costs. Some are visible — staff, lab, materials, rent — and others don't appear on any invoice but eat into your margin all the same. Knowing both, and reading them as a percentage of your revenue, is what separates those who run their clinic from those who only watch it bill. Here's the complete map.
The big visible categories
The first thing is to see the weight of each cost on revenue, not in loose euros. That way a clinic of any size can compare itself against a healthy range and spot which category has overrun. These are the big ones:
- Staff. By far the largest. Total cost — payroll plus associate commissions — sits in a normal range of 35–45% of revenue. Above 50%, review the structure, starting with the owner salary; below 30%, either you are paying under market or you are short-staffed.
- Lab. Closely tied to the mix: the more prosthetics and implantology, the more it weighs. It usually moves around 10–15%.
- Clinical materials. Consumables and disposables, normally 6–10%.
- Rent and premises. Location, utilities, maintenance: around 5–10% depending on the area.
- Equipment and depreciation. The wear of chairs, imaging equipment and technology, spread over time.
- Overheads. Insurance, software (including Verifactu-compliant billing), marketing, accounting, bank fees. Individually small, together they add up.
What's left after all of that is your profit margin — the number that really measures how the business is doing.
The hidden costs: the ones that don't arrive on an invoice
Here's what the books don't flag as a "cost" but really does cost you money — and it's usually where the most margin leaks away:
- Your own clinical salary, unaccounted for. If you work chairside and don't assign yourself a market salary, you think the clinic earns more than it does. We explain it in how much the owner earns.
- The idle chair. An empty chair-hour costs the same in rent, equipment and part of the staff — but it doesn't produce. It's the cost of low occupancy.
- The treatment plans that aren't accepted. Every rejected treatment plan is commercial and clinical work already done that doesn't turn into revenue. Pure opportunity cost — and among the easiest to recover by improving your treatment-plan acceptance rate.
- The patients who don't come back. Acquiring a new one costs much more than retaining one who already knows you. The silent loss of patients is a cost no one invoices — and one you tackle with a good recall and reactivation system.
- What you don't collect. Billed is not collected. A collection rate below 95% is worked-for money that gets lost along the way.
How to control them without going crazy
It's not about cutting what shows in the operatory. It's about looking at three things sensibly: the weight of each category on revenue (not the absolute amount), the two big ones — staff and the lab, where the money is — and the hidden costs, which are almost never watched and usually have more room than squeezing materials. And always read them alongside the margin: a cost is only "high" relative to what it produces.
In one line — Look at costs as a % of revenue · staff 35–45% · lab 10–15% · and don't forget the hidden ones: idle chair, lost treatment plans, patients who don't return, what you don't collect.
The problem isn't cutting, it's seeing
Most clinics don't have a problem of runaway costs; they have a problem of visibility. The visible expenses are split between the accountant and the bank, no one measures the hidden ones, and bringing it all into one clear picture requires cross-referencing billing, scheduling and costs every month. By hand it doesn't hold up.
Mola reads the activity from your practice-management software, cross-references it with your costs and shows you the complete structure — visible and hidden — as a percentage of your revenue, with its target range and an alert when a category drifts. You see where every euro goes without building a spreadsheet, and you know where to act. It's management analytics, it complements your accountant, it doesn't replace them. Watch them alongside the rest on your weekly dashboard.

About dental clinic costs
What are the main costs of a dental clinic?
The big categories are staff (by far the largest), the lab, clinical materials, rent and premises, and equipment depreciation. To that you add overheads (utilities, insurance, software, marketing, accounting). What's useful is not the amount in euros but its weight on revenue: that's where you quickly see which category has overrun.
What percentage of staff spending is healthy in a dental clinic?
Total staff cost — payroll plus associate practitioner commissions — sits in a normal range of 35–45% of revenue. Above 50% there is a structural problem, and the usual cause is an owner salary the business cannot carry. Below 30%, either you are paying under market or you are short-staffed. It's the clinic's largest category, so small deviations here move the margin a lot.
What are the hidden costs of a dental clinic?
They're the ones that don't arrive on an invoice but cost you money: your own clinical salary if you don't account for it, the idle chair time you pay for anyway, the treatment plans that aren't accepted, the patients who don't come back and what you don't end up collecting. They don't appear in the books as a "cost", but they erode the result as much as or more than the visible expenses.
How do I cut costs without lowering quality?
By starting with the two big categories — staff and the lab — and with the hidden costs, not by cutting clinical materials. Reviewing chair occupancy, the treatment mix, lab negotiation and the collection rate usually frees up more margin than squeezing things that show in the operatory. The key is to look at costs as a percentage of revenue and alongside the margin, not in absolute terms.
