Room cost sharing by shift calculator for professionals
Loading the calculator. If it does not appear, enable JavaScript in your browser.
When more than one professional uses the same room, how much should each one pay? The answer depends on a choice: divide the cost by the available shifts or only by the shifts actually used. The difference is idle time, and who bears it changes the result. The calculator shows both criteria.

What does each field mean?
| Field | What to enter |
|---|---|
| Monthly room cost | Proportional rent, building fees, electricity, cleaning and room maintenance. |
| Days of use in the month | Days the room is open. |
| Shifts per day | How many shifts the room has (for example, morning and afternoon). |
| Occupied shifts in the month | Total shifts used by all professionals. |
| Shifts the professional uses | The usage of the professional you want to split the cost for. |
How is the calculation done?
- Available shifts = days × shifts per day.
- Cost per available shift = cost ÷ available shifts.
- Cost per occupied shift = cost ÷ occupied shifts.
- Professional's share = cost per shift × the professional's shifts (under each criterion).
- Idle time = 1 minus (occupied shifts ÷ available shifts).
Worked hypothetical example
Hypothetical example: cost of R$ 6,000.00, 22 days, 2 shifts, 30 occupied shifts and 12 shifts for the professional.
| Step | Calculation | Result |
|---|---|---|
| Available shifts | 22 × 2 | 44 |
| Per available shift | 6,000 ÷ 44 | R$ 136.36 |
| Per occupied shift | 6,000 ÷ 30 | R$ 200.00 |
| Share by available | 136.36 × 12 | R$ 1,636.36 |
| Share by occupied | 200 × 12 | R$ 2,400.00 |
| Idle time | 1 minus 30 ÷ 44 | 31.8% |
How do you use the result?
Compare the split with the partner professional commission, another common model. To know how much each shift is worth to the clinic, see the clinical hour value and the schedule occupancy rate.
Frequently asked questions
How do you split the cost of a room among professionals?
Divide the monthly cost by the number of shifts and multiply by the shifts each professional uses. The base of the divisor changes the result.
What is the difference between an available shift and an occupied shift?
By available shift, the clinic absorbs the idle time. By occupied shift, whoever uses the room also shares the cost of the empty shifts.
Does the cost sharing need to be in a contract?
Yes. The criterion, amount, adjustment and cancellation rules should be in writing, reviewed by a lawyer.
