How to Calculate Your Expenses Per Treatment: A Step-by-Step Guide for Brow and Lash Artists

Running a beauty business isn’t all glam, lashes, and perfectly snatched brows—it’s also math. (Don’t roll your eyes yet; I promise it’s worth it!) Knowing your costs per treatment is the secret sauce to staying profitable, scaling your business, and indulging in that occasional fancy coffee without guilt. Let’s break it down.

Why Knowing Your Numbers Matters

Imagine this: you’ve spent the day laminating brows and lifting lashes, only to realize you’ve barely made enough to cover the products you used. Ouch. I am not even starting to talk about the rent girl.

Understanding your expenses per treatment ensures you price your services correctly, make consistent profits, and stay stress-free.

Breaking Down the Costs

Here’s a simplified example using Bronsun products (because, obviously, you’re using the best):

• Bronsun Gel Dye (New Formula): Each tube gives about 50 applications. Divide the cost of the tube by 50.

• Developer, Brushes, and Extras: Add these in—don’t skimp, even the cotton rounds count!

• Time Is Money: Factor in your hourly rate. Your skill isn’t free, darling.

Example:

Let's calculate the cost for a brow lamination treatment!

For this we will need the cost of products and the average consumption per product. Care line (Cleansing Mousse, Condtioner etc) can actually do up to 420 uses but we gotta be real here - we want it to be a spa treatment!

Bronsun Brow Perm Kit - 850 DKK (divide by 50 clients - 17 DKK/client)

Bronsun Gel Dye - 159,- DKK (divide by 50 clients - 3.18 DKK/client)

Cream Milk Activator - 99,- DKK (divide by 80 clients - 1.2 DKK/client)

Cleansing Mousse - 159,- DKK (divide by 200 clients - 0.7 DKK/client)

Conditioner - 169,- DKK (divide by 200 clients - 0.8 DKK/client)

Primer - 169,- DKK (divide by 200 clients - 0.8 DKK/client)

Color Fixing Lotion - 159,- DKK (divide by 200 clients - 0.7 DKK/client)

Total costs of Bronsun products per brow lamination = aprox 25,- DKK

Don't forget to include your rent, moms/VATs, your other disposable products and other expenses such as marketing into your cost calculation and adjust your prices accordingly!

Tools to Track It All

Use apps or spreadsheets to log expenses and calculate your treatment costs.
