Most salon owners track two numbers: how full the schedule is and how much came through the till. Both can look excellent while the business earns almost nothing.
The reason is that a salon does not sell «services» — it sells chair hours, and each service consumes a different amount of them at a different margin. Until the price list is measured in those terms, a busy month and a good month are two different things that happen to look alike.
The three costs behind one service
For any single service there are three costs, and salons routinely count only two.
Product. Not the price of the bottle — the portion actually used. A tube of colour that costs 600 and covers three clients contributes 200, not 600. Salons that price from the shelf price overstate the cost of some services and, more often, forget product entirely on services where it is «just a bit of everything».
The master's share. Straightforward when it is a fixed percentage, less so when it is a percentage of revenue. That structure pays the same share on a service that consumed 900 of product as on one that consumed nothing — so the salon carries the product cost alone.
Chair time. This is the one that gets missed. Rent, utilities, reception, software and administration do not care which service is being performed; they are paid per hour the salon is open. Divide those fixed costs by the realistic number of productive chair hours in a month and you get a cost per hour of chair. Every service occupies some of it.
Work out your cost of a chair hour
Take your monthly fixed costs — rent, utilities, admin salaries, software, accounting, marketing. Say 84,000. Then count realistic productive hours: three chairs, ten working hours a day, twenty-four days — but honestly, chairs are not busy every hour. At 60% occupancy that is 3 × 10 × 24 × 0.6 ≈ 432 hours.
84,000 ÷ 432 ≈ 194 per hour of chair. That number now belongs in every service calculation you make.
Put it against the price list
Now the price list becomes readable. A manicure at 600 that takes an hour and uses 80 of product, with a 40% master's share (240), leaves 600 − 80 − 240 − 194 = 86. A colour at 2,200 that takes two and a half hours and uses 700 of product, same 40% share (880), leaves 2,200 − 700 − 880 − 485 = 135.
Both look modest, and that is the point: a price list built on «what competitors charge» tends to land just above cost without anyone noticing. The comparison also shows something useful — the colour ties up two and a half hours of chair to earn roughly what the manicure earns in one. Three manicures in that window would earn 258.
What to do with the result
Sort every service by two columns: what it leaves after all three costs, and how many chair hours it consumes. The services in the bottom-left corner — low margin, high chair time — are the ones filling your book and emptying your account.
You have three moves, and they are not all price rises. Raise the price where the service is genuinely below cost. Shorten the service where the time, not the price, is the problem. Or stop promoting it and give the slot to something that earns more per hour — the same logic as profit per chair and per master.
Fix the master's share while you are there
If masters are paid a percentage of revenue, the salon absorbs every product increase alone. Moving to a percentage of the service margin — or at least deducting product before the share is calculated — aligns the interest: a master who chooses the efficient product is no longer indifferent to its cost.
Where to start
Pick your ten most frequently booked services. For each, write down the product portion, the master's share and the chair time. Work out your cost of a chair hour once and apply it to all ten. You will usually find two or three services that lose money on every booking and one that quietly carries the salon — see also the real owner profit in a beauty salon.

FAQ
Add three things: the product actually used (not the bottle price — the portion), the master's share for that service, and the chair time it occupies multiplied by your cost of an hour of chair. The third one is what most salons skip.
Usually because the busiest services are the least profitable ones. Long, cheap services fill the book and block the chair, while short high-margin ones have no room left.
From the service margin where you can. A percentage of revenue pays the same on a colour that consumed 900 of product as on a haircut that consumed nothing.
Whenever product costs move noticeably, and at minimum twice a year. Product prices drift up quietly; a price list left alone for two years is usually below cost on the services that use the most product.
