The list, ranked by what it clears, not by what it sells

By the end, you'll have a table of all your services ranked by what you clear per hour, not by what each one bills, ready to decide who gets a price increase and who you let go.

If someone asked you right now which service makes you the most money, you'd probably say the one you sell the most. That answer misses the mark for three reasons: what you sell the most isn't what you keep the most, the price has to be stripped of what it costs you to deliver it, and the hours you put in count too.

Those three numbers usually get looked at separately, service by service. It's time to bring them together in one place: a list of all your services, one under the other, ranked by what you actually keep, not by what each one brings in. Rank it wrong, and you'll decide wrong. So first, you need to build it right.

The number that ranks the list: margin per hour

For each service, you need three numbers. The price you charge. What it costs you to deliver it: materials, payment processing fees, whatever you spend each time you sell it. And the hours it takes you from start to finish, counting the part nobody sees: getting ready, cleaning up, writing the confirmation message.

Subtract the cost from the price and you get the margin. Divide the margin by the hours and you get the margin per hour: what you actually keep for every hour you put into that specific service. That number, not the price and not the monthly total, is what ranks the list.

Notice that the highest price doesn't guarantee anything. In the table coming up, lash extensions cost $45, more than a gel manicure, and it's still the service that earns the least per hour of the four: it takes a full two hours and a higher material cost. A pretty price on the menu doesn't mean much if the hours eat it up behind the scenes.

Here's an example outside the beauty business, so you can see the math works the same in any trade. A personal trainer charges $40 for a single one-hour session, with almost no cost: $40 clean per hour. The same trainer sells a monthly training plan for $150 that takes six hours spread across the month, between planning workouts and answering questions over WhatsApp: split across those hours, the plan nets $25 per hour. The plan brings in more money upfront. The single session nets more per hour worked.

How to build the list
  1. 1List every service separately
    Don't group them. If you have three types of manicure at different prices, that's three rows, not one.
  2. 2Write down the selling price
    The one you actually charge, with your usual discount applied if you always apply it. It's the one on your price list or your catalog if you sell online.
  3. 3Subtract the cost of delivering it
    Materials, payment processor fees, anything you spend each time you sell it. What's left is your margin.
  4. 4Divide the margin by the hours
    Include prep and wrap-up, not just the time in front of the client.
  5. 5Also write down how many times you sell it each month
    This column doesn't rank anything, but you'll need it in the next lesson. Pull it from your appointment book or last month's sales, counting how many times you did each service.
  6. 6Sort from highest to lowest margin per hour
    That order, not the billing order, is the real one.

The list, with real numbers

Here's how the table looks for a beauty salon, with the four columns that matter and total billing next to them for comparison.

The service that sells the least earns the most per hour
ServicePriceCostHoursMargin/hourMonthly billing
Gel manicure25€3€1 hr22€$1,000 (40 sales)
Laser hair removal (session)35€1€0.5 hr68€$700 (20 sales)
Lash extensions45€6€2 hr19,50€$450 (10 sales)
Event makeup60€5€2 hr27,50€$300 (5 sales)

Look at the last two columns: they don't match. By revenue, the gel manicure comes out on top with $1,000 a month, and laser hair removal comes in second with $700. By margin per hour, the order flips: laser hair removal nets $68 for every hour worked, more than triple the manicure, which comes in at $22.

Laser hair removal takes the least time and uses the least material, and it still comes in second for billing. If you only looked at the total, you'd treat it as a secondary service, the kind you squeeze in between other appointments. Looking at margin per hour, it's your best service by far, and it's the one that should get the schedule slots that right now go out on a first-come, first-served basis.

Also take a look at lash extensions: it's the second-highest price on the menu, $45, and yet it earns the least per hour, $19.50. Two hours of work and a higher material cost eat up most of the margin. If you only looked at the sale price, you'd think it was a premium service. By margin per hour, it's at the bottom of this list.

Event makeup lands in the middle, at $27.50 per hour: not the best, not the worst, but better positioned than two services that bill more than it each month. That's proof that ranking by margin per hour doesn't mean always favoring the priciest or the cheapest option, it means favoring what truly pays off for the time you put in.

What every hour of work actually earns you
Laser hair removal$68/hour
Event makeup$27.50/hour
Gel manicure$22/hour
Lash extensions$19.50/hour
The costly mistake: ranking by what brings in the most
If you rank the list by total billing, you'll end up protecting the wrong service. The manicure in this example looks like the star because it's the most requested and brings in the most money each month, so it's easy to keep giving it prime time slots and discounts to avoid losing clients. Meanwhile laser hair removal, which earns triple per hour worked, gets stuck with whatever slots are left over. There's a cost you won't see on the bill: every hour the schedule gives to manicures is an hour that can't go to laser hair removal when someone asks for it, and if the slot's already taken, that client heads to another salon. The result: you work more hours than you need to and earn less than you could. Total billing tells you what moves. Margin per hour tells you what's worth moving.
What you'll walk away with
  • You have the full table of your services: price, cost, hours, margin per hour, and billing for each one
  • The list is sorted by margin per hour, not by what each service bills
  • You know which service is truly your most profitable, even if it's not your top seller
  • With this list in front of you, the next lesson decides who gets a price increase without losing the client, and the one after that decides who you push this season and who you let fade out

Test yourself

Answer before opening each one. If one gives you trouble, go back to the section that explains it.

1. Your top-earning service each month is also the one that eats up the most hours on your calendar every week. What do you do?

Look at its margin per hour compared to the rest. If it's one of the lowest on the list, you're giving it the wrong calendar slot: it earns a lot because you spend a lot of time on it, not because it's profitable. Take hours away from it and give them to the service that earns the most per hour.

2. A new service has been on the menu for two months, it's still selling slowly, and you're not sure whether to give it more visibility.

Calculate its margin per hour just like you did for the rest, and place it in the table where that number puts it, not where its current sales put it. If the margin per hour is high, it deserves more visibility even if revenue is still low; if it's low, waiting for more sales won't fix that.

3. Two services have the same margin per hour, but one sells thirty times a month and the other sells three.

The margin per hour ties them, but they don't carry the same weight in your week: the one that sells thirty times takes up far more of your calendar overall. The times-sold column, even though it doesn't determine the ranking, tells you which of the two matters more to your real business. That's exactly what you'll need for the next lesson.

With the list finished and ranked, the one at the top is a candidate for a price increase. The next lesson asks whether it can handle the increase without the client walking away, and how to test that without anyone noticing.
