Subtract commitments and a deliberate reserve, convert the remaining slots into whole appointments, then divide by appointments per new client.
Ten blank calendar spaces do not always mean room for ten new clients. An appointment may require several slots, and a new client may need several appointments within the planning period. Existing commitments and work held in reserve also matter.
The Appointment Business Growth Planner → makes those units explicit. It is a general planning tool for appointment-based businesses, not a scheduler, patient system or clinical capacity assessment. Use aggregated figures only.
Choose one period and one slot unit
State the planning period and define a slot. It could be a standard booking unit in your own schedule. Count total slots before subtracting committed work; record commitments separately. Add the reserve you intend to keep rather than assuming every unbooked moment is available to sell.
Next, enter slots per appointment and appointments per new client within that same period. The planner’s labeled operational default is one slot per appointment. A blank reserve uses a labeled zero, which is an input to review rather than a recommendation.
A fictional schedule
Suppose the period has 100 total slots, of which 60 are committed. The owner reserves another ten. Each appointment takes one slot, and each new client is planned for two appointments in the period.
- Open slots: max(0, 100 − 60 − 10) = 30.
- Whole appointment capacity: floor(30 ÷ 1) = 30 appointments.
- Whole new-client capacity: floor(30 ÷ 2) = 15 new clients.
If each appointment instead requires two slots, appointment capacity falls to 15 and new-client capacity becomes floor(15 ÷ 2), or seven whole new clients. The spare appointment does not constitute another complete two-appointment client plan.
Attendance does not create more booking capacity
Now keep the original 15-client scenario and assume 80% attendance. Thirty bookings imply 24 attended and six unattended appointments on average. The schedule still reserved 30 bookings. The six modeled unattended visits are not six slots you can sell again in advance.
Changing attendance changes modeled delivery and contribution. It does not increase the capacity calculation. Use the separate booking, attendance and client definitions → when reconciling reports.
Averages need an operational check
The model does not know whether the open times suit the services or clients involved. Check appointment length, room or equipment availability, staff coverage, preparation and cleanup, and any professional restrictions with the responsible people. If the business is a healthcare practice, this general worksheet does not establish clinical appropriateness or regulatory compliance.
Use the selected-client input to model a goal deliberately. If it is blank, the planner uses computed new-client capacity. A goal above capacity remains visibly over capacity; the tool does not silently turn it into a safe booking plan.
Make a decision you can inspect
Save the period and unit definitions with the result, then place a proposed client pattern on a real calendar. Where costs and attendance are unknown, keep the economics unknown until someone supplies the evidence. Do not enter patient names or individual bookings to fill a gap.
For the visitor side of the process, ThinkDMG’s web-design services → connect naturally to an understandable appointment path. The planner tells you about your entered schedule, while the website helps explain the actual next step; neither proves new demand.
