About this calculator
Exam rooms are a fixed capacity constraint just like beds in a hospital. This calculator compares the hours your exam rooms are actually occupied with appointments against the total hours they're open, producing a utilization percentage that tells you whether you have room to add appointments or need another room or doctor before you can grow. Most well-run general practices run 65-80% utilization during core hours; above 85% you're likely turning away same-day requests and pushing wait times, while below 55% signals either a marketing problem or too much fixed capacity for current demand.

FAQ
What utilization rate should I aim for?
65-80% is the healthy operating range for general practice. Anything consistently above 85% means clients wait too long for appointments and staff have no buffer for emergencies or add-ons, which drives no-shows and burnout. Below 55% usually means you can absorb growth without adding rooms.
Does this account for staggered scheduling and double-booking?
No — it's a straightforward capacity model based on average visit length. Practices that double-book routine rechecks or run a doctor across two rooms will show higher effective throughput than this formula predicts, so treat the output as a conservative baseline.
How do I raise utilization without adding a room?
Shorten average visit time with better pre-visit triage and technician-driven history taking, extend hours on your slowest weekday, or add an urgent-care block that fills same-day cancellations. Each of these increases booked hours against the same fixed capacity.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
