Below this hourly rate, a treatment does not even cover the practice's fixed costs.
Indicative range only, not an official benchmark: for most practices the real hourly cost is roughly €40–€90/h.
The hourly cost is the starting point. The rest is the work.
The 5-12 hours figure is an internal EUSTAK estimate. The 12-15 minutes per invoice comes from published accounts-payable benchmarks on manual invoice handling (Ardent Partners, State of ePayables). Your figure depends on chairs and invoice volume.
This is today's theoretical hourly cost.
The real hourly cost changes every month with actual costs and schedule saturation. EUSTAK calculates it automatically from your invoices and tells you which treatments are truly profitable, one by one.

The chair hourly cost is the practice fixed cost divided by the actually productive hours. The formula is: hourly cost = annual fixed costs ÷ productive hours per year.
Fixed costs include rent, staff, utilities, sterilisation, insurance, software and equipment depreciation. Productive hours are the open hours multiplied by the number of chairs and by the real schedule saturation — not the theoretical hours.
Why it is the single most important number for profitability
Without the hourly cost you cannot tell whether a treatment is really profitable. A €1,200 implant with €350 in materials and €200 in lab looks like €650 profit. But if the hourly cost is €80/h and it takes 3 hours, real profit is €410: the gap is huge and multiplies with every discount.
Knowing the hourly cost tells you the minimum rate below which you are working at a loss, treatment by treatment.
Theoretical vs real cost
This calculator gives you the theoretical hourly cost, on paper. The real cost changes every month with actual expenses and the true schedule saturation.
That is why the hourly cost should be recalculated continuously, not just once: an empty chair or a rise in fixed costs shifts it immediately.
Break-even point: how many chair hours you need to cover costs
The break-even point is the number of chair hours you need to bill every month just to cover fixed costs, before you start making a profit. It is calculated by dividing monthly fixed costs by the average margin you make on each billed hour: average hourly rate minus direct variable costs (materials, lab).
Example: fixed costs €11,450/month, average rate €90/h with €15/h in direct costs — margin per hour is €75. The break-even point is 11,450 ÷ 75 ≈ 153 billed hours per month. Below that threshold the practice runs at a loss; above it, it starts generating real, not just theoretical, profit.
