Frequently asked questions

How do I calculate appointment duration?

Subtract start time from end time. For multiple appointments, sum all durations. Our calculator handles hours and minutes across midnight.

How do I calculate daily appointment capacity?

Divide available working hours by average appointment duration. For example: 8 hours 梅 45 min appointments = ~10 slots per day.

How do I add buffer time between appointments?

Add your buffer time to the appointment duration before calculating capacity. For example: 45-min appointment + 15-min buffer = 60-min slots.

What is a good default appointment length?

It depends on the service: a standard consultation is often 30 minutes, a follow-up 15, and a first visit or procedure 45-60. Set a default per service type so booking, reminders, and capacity all use consistent durations.

How does appointment duration affect utilization?

Utilization is booked time divided by available time. Durations set too long leave gaps; too short causes overruns and late-running days. Track actual versus scheduled duration by service to tune both capacity and no-show buffers.
