Are You Actually Making Money? Here's How to Calculate Your Cost Per Lash Service

One of the biggest mistakes lash artists make is setting their prices based on what everyone else in their area charges. The problem? Their business expenses aren't the same as yours.

If you don't know what each service truly costs you, you could be working long hours and still making very little profit.

The good news is that calculating your cost per service is easier than you think—and it's one of the most important numbers every beauty professional should know.

Step 1: Calculate Your Product Cost

Start by adding up the cost of every product you use during a service. This includes anything that is consumed or needs to be replaced over time.

Examples include:

• Lash trays

• Adhesive

• Primer

• Cleanser

• Remover

• Tape

• Gel eye pads

• Micro swabs

• Mascara wands

• Glue rings

• Sealant

• Any other products used during the appointment

The easiest way to calculate this is to determine how many services you get from each product.

Formula:

Cost of Product ÷ Number of Services = Cost Per Service

Do this for each product, then add the totals together.

Step 2: Add Your Disposable Supplies

These are the items that are thrown away after every client.

Examples include:

• Bed cover or disposable table paper

• Cotton rounds

• Lip applicators

• Gloves

• Paper towels

• Sanitizing supplies

Add these together to find your disposable supply cost for one appointment.

Step 3: Pay Yourself for Your Time

Your time has value.

Decide what you want to earn per hour before calculating your pricing.

Formula:

Hourly Wage × Service Time (in Hours) = Labor Cost

Example:

• Desired wage: $40 per hour

• Full set appointment: 2.5 hours

$40 × 2.5 = $100 labor cost

If you don't pay yourself, your business isn't truly profitable—you're simply working for free.

Step 4: Don't Forget Your Overhead

Many artists forget to include the expenses that keep their business running.

Examples include:

• Rent

• Utilities

• Insurance

• Booking software

• Website

• Phone

• Marketing

• Continuing education

• Equipment replacement

• Licensing

• Laundry

• Cleaning supplies

• Internet

• Business subscriptions

Add your monthly business expenses together.

Then calculate your overhead cost per appointment.

Formula:

Monthly Overhead ÷ Average Monthly Appointments = Overhead Cost Per Service

Example:

• Monthly overhead: $2,000

• Average appointments: 80

$2,000 ÷ 80 = $25 per appointment

Step 5: Include Payment Processing Fees

If clients pay with a credit card, those fees reduce your profit.

A good estimate is between 2.5% and 3.5% of the service price.

Example:

$150 service × 3% = $4.50

Putting It All Together

Let's look at an example.

Full Set

• Product Cost: $12.50

• Disposable Supplies: $3.00

• Labor: $100.00

• Overhead: $25.00

• Credit Card Processing: $4.50

Total Cost Per Service = $145.00

If you charge $180, your profit before taxes is:

$180 − $145 = $35.00

Knowing this number helps you confidently decide whether your pricing supports your goals—or needs to be adjusted.

How to Set Your Prices

Once you know your cost per service, pricing becomes much easier.

Formula:

Service Price = Cost Per Service + Desired Profit

Or, if you want to maintain a specific profit margin:

Service Price = Cost Per Service ÷ (1 − Desired Profit Margin)

Example:

• Cost per service: $80

• Desired profit margin: 40%

$80 ÷ (1 − 0.40) = $133.33

You could round that to $135.

Final Thoughts

Successful lash artists don't guess their pricing—they calculate it.

Understanding your cost per service gives you confidence in your prices, helps prevent burnout, and ensures your business remains profitable as product costs and expenses change over time.

Remember, you're not just selling beautiful lashes. You're providing a professional service backed by your education, experience, supplies, business expenses, and valuable time.

Know your numbers, price with confidence, and build a business that supports the life you want—not one that leaves you wondering where all the money went.
