Four numbers that govern the project
Monthly fixed costs determine how much the salon has to produce simply to exist, regardless of how much it works. Average margin per service determines how much each appointment contributes to covering them. From their ratio comes the number of appointments needed per week.
Weekly capacity — stations times opening hours, divided by average service duration — tells you how many appointments physically fit. If the number needed exceeds what's possible, the project doesn't hold and has to be changed before you start.
Sustainable ramp-up months complete the picture: how long you can carry a situation where appointments fall short of what's needed. It's the quantity that sets how much risk you can afford on the other three.
How much each constrains the other decisions
The chart is qualitative and shows how far each quantity constrains the project's choices.
What to do when the numbers don't work
The table gives, for each imbalance, the levers actually available.
| Imbalance | Possible levers | Lever to avoid |
|---|---|---|
| You need more appointments than fit | Cut fixed costs or raise margin | Hoping for occupancy beyond capacity |
| Margin per service too low | Revise the list and the service mix | Increasing volume alone |
| Fixed costs too high | Smaller space, fewer stations | Cutting the ramp-up reserve |
| Reserve insufficient | Reduce the initial investment | Opening anyway and postponing the problem |
The four quantities
Monthly fixed costs
Everything paid with an empty salon.
Average margin per service
How much each appointment contributes.
Weekly capacity
Stations by hours, net of non-billable time.
Sustainable months
How long you can run below break-even.
How to use the numbers
- Calculate the appointments needed before any other decision.
- Compare it with real physical capacity, not theoretical capacity.
- Revise the four quantities with actual data after three months.
Real capacity is always lower than theoretical: not all opening hours are productive, services overlap badly, some days are quiet. Using theoretical capacity in the calculation produces plans that look solid and aren't.
After the first three months the estimates should be replaced with real data. That's when the project stops being a hypothesis: actual average margin and real occupancy tell you whether the levers to pull are the ones you planned or different ones.
The service to include in the new salon
Saloria enters the opening project as a consultation tool, not as management software. The new salon can use it to guide the first visit, analyze the face, build the look plan and generate a protocol useful for the team. This way technology isn't an accessory: it becomes part of positioning and professional sales.

Frequently asked questions
Which calculation comes first?
Fixed costs divided by average margin per service: it gives the appointments needed, to be compared with real capacity.
What if the numbers don't work?
Reduce fixed costs or raise margin per service. Hoping for occupancy above physical capacity isn't a lever.
When should you revise the estimates?
After three months, replacing them with real data on margin and occupancy.
