1. Enter fixed monthly costs
Include recurring overhead that does not change directly with each additional appointment.
2. Enter variable cost per appointment
Use an average of appointment-linked labor, consumables, card fees, or other incremental cost.
3. Enter completed monthly volume
Base this on completed billable appointments rather than maximum calendar slots.
4. Review the break-even amount
This is the average price needed to cover the entered fixed and variable costs at the stated volume.
5. Test alternative volumes
Re-run the model at conservative and busy-month appointment counts to see how fixed-cost allocation changes.
