How it works
Estimate how many appointments your team can offer in a day. Each staff member's working minutes are divided by the service duration plus the buffer you keep for cleaning or preparation, rounded down to whole appointments, and multiplied by the number of staff who can perform the service.
Treat the result as a theoretical maximum. Breaks, leave, late arrivals, a mix of services and real customer demand all reduce practical capacity. Add an average price to see the most revenue a fully booked day could bring.
Formula
- Appointments per staff = round down (working hours × 60 ÷ (service minutes + buffer minutes))
- Daily capacity = appointments per staff × eligible staff
- Maximum daily revenue = daily capacity × average service price
Worked example
A salon has 2 stylists working 8 hours. A haircut takes 45 minutes plus a 15-minute buffer, so each stylist can take 480 ÷ 60 = 8 appointments, and the salon can offer 16 a day.
At an average of ₹400 per haircut, a fully booked day is worth ₹6,400. Cutting the buffer to 5 minutes gives 480 ÷ 50 = 9.6, rounded down to 9 per stylist, or 18 a day.
How to use these calculators well
Keep every number on the same basis. If your selling price excludes GST, your cost should exclude input GST too. Mixing a tax-inclusive price with a tax-exclusive cost is the most common reason a margin looks better than it really is.
Use real numbers from your own records. Last month's bills, purchase invoices and appointment calendar give far better answers than guesses. vkRetA keeps those records for you, so the inputs for these calculators are already in your workspace.
