Customer Retention Rate


Customer retention rate measures the ability of an eyelash salon to retain its existing customers over a specific period of time.

Use Case

Customer retention rate is crucial for evaluating customer loyalty, satisfaction, and revenue growth potential. By analyzing this KPI, business owners can understand how successful they are in keeping customers coming back to their salon. A high retention rate may indicate that the salon is providing exceptional service and gaining customer loyalty.

How To Calculate KPI

Customer Retention Rate = ((E-N)/S) x 100

  • E - the number of customers at the end of a specific time period
  • N - the number of new customers during the same time period
  • S - the number of customers at the start of the time period

Calculation Example

Suppose an eyelash salon has 200 customers at the beginning of the month, and 40 new customers come throughout the month. After one month, the salon has 220 customers. Therefore,

  • E = 220
  • N = 40
  • S = 200

Customer Retention Rate = ((220-40)/200) x 100 = 90%

KPI Advantages

  • Helps to measure customer loyalty
  • Indicates how successful the salon is in providing customer satisfaction
  • Helps to make informed decisions to strengthen customer relationships

KPI Disadvantages

  • Does not capture the quality of customer retention
  • May not accurately reflect the entire picture of customer satisfaction

KPI Industry Benchmarks

  • A customer retention rate of 80% or higher is considered strong in the eyelash salon industry.

Tips & Tricks:

  • Offer special promotions or discounts for repeat customers to encourage loyalty

What Are the Top Seven Eyelash Salon KPI Metrics? How to Track and Calculate

Average Revenue per Customer

Definition: Average revenue per customer is a KPI metric that measures the amount of money generated by each customer on average. It is calculated by dividing the total revenue by the total number of customers.

Use Case: This KPI is essential for salon owners to understand the spending patterns of their customers and track the overall revenue generated by each one. By monitoring the average revenue per customer, owners can better understand how much their customers are willing to spend and make pricing decisions to maximize revenue.

How To Calculate KPI:

(Total Revenue / Total Number of Customers)

Calculation Example: If a salon generates a total revenue of $30,000 in a month and serves 500 customers, the average revenue per customer would be $60.

KPI Advantages: Helps to identify the most profitable customers and the most popular services that generate the most revenue. It also helps to monitor customer retention rate and helps with pricing strategies.

KPI Disadvantages: Average revenue per customer does not consider the frequency of customer visits and the number of services they avail at the salon.

KPI Industry Benchmarks: The average revenue per customer in the beauty industry is around $50 to $80, but it can vary depending on the location, size, and services offered by the salon.

Tips & Tricks:

  • Offering attractive packages and discounts can help increase the average revenue per customer.
  • Upselling and cross-selling services can also help boost the average revenue per customer.
  • Use the KPI in conjunction with customer acquisition cost to measure effectiveness and improve overall marketing strategy.

Employee satisfaction index


The employee satisfaction index is a KPI that measures how satisfied your employees are with their job, work environment, and management. It helps you understand the overall morale of your workforce and identify areas of improvement.

Use Case

The employee satisfaction index can be used to analyze and evaluate the effectiveness of HR policies and employee engagement initiatives to ensure better teamwork, productivity, and employee retention.

How To Calculate KPI

KPI = (Number of satisfied employees/Total number of employees surveyed) x 100

Calculation Example

If you have surveyed 100 employees and 70 of them are satisfied, the index value would be:

KPI = (70/100) x 100 = 70%

KPI Advantages

  • Helps identify areas of improvement for employee engagement and satisfaction
  • Encourages higher employee retention rates
  • Indicates the effectiveness of HR policies and initiatives, and their impact on employees

KPI Disadvantages

  • May not always provide accurate information due to employees' reluctance to share their honest opinions
  • Results can be biased if dissatisfied employees are unwilling to participate in the survey
  • May not be useful in organizations with a large number of part-time or temporary employees

KPI Industry Benchmarks

The industry benchmark for the employee satisfaction index varies depending on the location, industry, and company size. On average, the index value ranges from 65% to 85%, with scores above 70% indicating satisfactory employee satisfaction levels.

Tips & Tricks

  • Conduct surveys regularly to stay updated on employee satisfaction
  • Incorporate feedback from employees to improve the work environment and HR policies
  • Offer employee engagement initiatives, such as health and wellness programs or employee appreciation events

Inventory turnover ratio

An inventory turnover ratio is a measure of how well a company is managing its inventory. It shows how many times a company sells and replaces its inventory over a given period of time. This KPI is particularly important for eyelash salons that sell products because it helps determine how profitable the business is and how well it is managing its inventory.


The inventory turnover ratio is the number of times a company sells and replaces its inventory during a specific period. This ratio indicates how quickly a company is selling its inventory and how efficiently it is managing its stock. A high ratio means the company is selling its products quickly and efficiently, which could lead to higher profits.

Use Case

For eyelash salons, the inventory turnover ratio is important because they sell a range of products including eyelash extensions, adhesives, and accessories. It is important for salons to manage their inventory effectively to avoid overstocking, which can lead to dead stock and wasted money. The inventory turnover ratio shows how well the salon is managing its inventory and highlights any areas that need to be improved.

How To Calculate KPI

The formula for calculating inventory turnover is:

Inventory turnover ratio = Cost of goods sold / Average inventory

To calculate the average inventory, you add the beginning inventory and ending inventory together and divide by two. The cost of goods sold is the cost of all the products sold during the period.

Calculation Example

Let's say an eyelash salon had a cost of goods sold of $50,000 and an average inventory of $10,000. The inventory turnover ratio would be:

Inventory turnover ratio = $50,000 / $10,000 = 5

This means that the eyelash salon sold and replaced its inventory five times during the period.

KPI Advantages

  • Shows how quickly a company is selling its inventory
  • Helps identify inventory management issues
  • Highlights any areas where a company can improve efficiency

KPI Disadvantages

  • Does not take into account inventory cost fluctuations
  • May not be applicable to service-based businesses
  • May not accurately reflect inventory management issues for businesses with seasonal fluctuations

KPI Industry Benchmarks

The inventory turnover ratio varies by industry. According to the National Association of Wholesaler-Distributors, the average inventory turnover ratio for wholesalers is 6-8 times a year, while for retailers, it is 4-6 times a year. However, it is important to note that benchmarks can vary by region and company size. Comparing to industry benchmarks can help identify areas that need improvement in inventory management.

Tips and Tricks

  • Regularly review inventory levels to ensure optimal stock levels
  • Ensure accurate tracking of inventory levels by investing in a good inventory management system
  • Consider conducting a physical inventory count periodically to ensure accuracy

Top Seven Eyelash Salon KPI Metrics: How to Track and Calculate

Customer satisfaction score

Definition: The customer satisfaction score (CSS) measures how satisfied your customers are with your services or products. CSS KPI helps businesses understand the level of satisfaction of their customers and how likely they are to remain loyal.

Use Case: CSS is crucial for measuring customer loyalty and retention. It is an essential metric for eyelash salons that want to improve their services and grow their client base.

How to Calculate KPI: CSS is calculated by asking customers to rate their satisfaction levels from 1-10 after receiving a service or purchasing a product. The formula for calculating CSS is:

CSS = (Number of satisfied customers / Total number of customers surveyed) x 100

Calculation Example: If you survey 100 customers, and 80 of them are highly satisfied, your CSS would be:

CSS = (80 / 100) x 100 = 80%

KPI Advantages: CSS helps to identify the strengths and weaknesses of your products/services. It helps to retain existing customers and attract new ones. Also, it helps to improve the overall customer experience.

KPI Disadvantages: Interpreting CSS can be challenging because it does not tell you what went wrong. It only tells you how much satisfaction people have with your services or products. Additionally, other factors such as price and customer service can affect customer satisfaction, and CSS may not take those factors into account.

KPI Industry Benchmarks for CSS: According to industry benchmarks, a CSS of 80% is considered good for eyelash salons. However, the ideal CSS score can vary depending on the industry and customer expectations.

Tips and Tricks:

  • Focus on continuous improvement to maintain high CSS.
  • Train your staff to provide better customer service
  • Use feedback from customers to address areas of dissatisfaction

Conversion rate of first-time customers


The conversion rate of first-time customers is the percentage of customers who, after visiting an eyelash salon for the first time, choose to return for a second appointment within a given timeframe.

Use Case

This KPI can help determine the effectiveness of an eyelash salon's marketing, customer service, and overall experience. A high conversion rate indicates that the salon is providing a positive experience that encourages customers to return.

How to Calculate KPI

The formula for calculating the conversion rate of first-time customers is:

(Number of first-time customers who return for a second appointment / Total number of first-time customers) x 100%

Calculation Example

If an eyelash salon had 50 new customers in a month and 15 of those customers returned for a second appointment within the month, the conversion rate would be:

(15 / 50) x 100% = 30%

KPI Advantages

  • Provides insight into customer satisfaction and loyalty
  • Can reveal areas for improvement in marketing, customer service, and overall experience
  • Helps measure the lifetime value of a customer

KPI Disadvantages

  • May not be relevant for all types of businesses
  • May be influenced by factors outside the salon's control, such as seasonality or location
  • Does not account for customers who recommend the salon to others without returning themselves

KPI Industry Benchmarks for the KPI: 'Conversion rate of first-time customers'

The average conversion rate of first-time customers across the eyelash salon industry is around 25%. However, this can vary depending on factors such as the salon's location, competition, and marketing efforts.

Tips & Tricks

  • Offer incentives to encourage first-time customers to return, such as a discount on their second appointment
  • Ensure that the salon provides a positive and memorable experience for first-time customers, including exceptional customer service
  • Encourage customers to leave a review to help attract more first-time customers and build the salon's reputation

Average wait time for appointments


Average wait time for appointments is the amount of time that a client waits before getting their eyelash service done in a salon. It measures the efficiency of a salon's appointment-making process.

Use Case

This KPI is essential for salons to ensure customer satisfaction and retention. The longer the wait time, the more likely clients are to seek services elsewhere.

How To Calculate KPI

To calculate the average wait time for appointments, take the total wait time for all clients in a day and divide by the number of clients served that day.

KPI Formula:

(Total wait time for all clients in a day) / (Number of clients served that day)

Calculation Example

Suppose a salon served 20 clients on a given day, and the total wait time for all the clients was 180 minutes.

KPI Example:

(180 minutes) / (20 clients) = 9 minutes

KPI Advantages

  • Helps to identify the efficiency of the current appointment-making system in the salon.
  • Assists in improving customer experience and satisfaction.

KPI Disadvantages

  • Does not measure the quality of the service provided.
  • Can be affected by external factors such as traffic or weather conditions.

KPI Industry Benchmarks

According to industry benchmarks, the average wait time for eyelash salon appointments should be between 7-10 minutes.

Tips & Tricks

  • Use online scheduling software to reduce wait times and increase efficiency.
  • Strive to exceed the industry benchmark by offering a comfortable waiting area or complimentary services during wait times.
  • Continuously gather feedback from clients about their wait times and make improvements accordingly.
