Average Customer Spend Per Visit

In the restaurant industry, measuring average customer spend per visit is critical for evaluating how well your business is doing. It refers to the average amount of money each customer spends during their visit to your restaurant. Tracking it helps you understand the overall revenue trends and determine how many customers it takes to achieve a specific revenue target.


The Average Customer Spend Per Visit KPI represents the mean amount of money that a customer spends every time they visit your restaurant.

Use Case

This KPI can help you determine the profit margin per customer, the efficiency of your marketing strategies and evaluate the effectiveness of the menu pricing strategy. Knowing how much your customers spend, you can make essential changes to your menu, promotions and optimize operations to increase revenue.

How to Calculate KPI

Calculating Average Customer Spend Per Visit KPI is easy. Take the sum of all revenue generated in one day and divide it by the total number of customers who visited the restaurant that day.

(Total Revenue/ Total Customers) = Average Customer Spend Per Visit

Calculation Example

Imagine that your restaurant has served 200 customers today, earning $2000 in total revenue. Based on the formula mentioned above, the average customer spend per visit is $10.

KPI Advantages

Customer Retention Rate


Customer retention rate is a metric that measures the percentage of customers who continue to do business with a company over a given period of time. This KPI is a critical indicator of a restaurant's ability to attract and retain customers over time. Higher customer retention rates imply higher customer satisfaction and a loyal customer base.

Use Case

The customer retention rate is an essential metric for sushi restaurants to measure their customers' loyalty. Striving to keep your customer retention rate high is critical for identifying potential issues in your restaurant's service, menu, or atmosphere that could lead customers to switch to another eatery. Tracking customer retention rate can help you identify changes in customer behavior, such as a decline in customer satisfaction or increased competition. Thus, you become proactive in addressing potential issues and retaining diners over the long term.

How To Calculate KPI

Calculating customer retention rate is simple:

Customer Retention Rate = (CE-CN)/CS

  • CE: number of customers at the end of a period
  • CN: new customers acquired during the same period
  • CS: number of customers at the start of the period

Calculation Example

Assume that a sushi restaurant has 300 customers at the start of January, and 50 new customers join in the same month. At the end of the month, 230 of those customers return. Following the formula:

Customer Retention Rate = (CE-CN)/CS * 100%

  • CE: 230 customers
  • CN: 50 new customers
  • CS: 300 customers

Customer Retention Rate = (230-50)/300 * 100% = 60%

KPI Advantages

  • Customer retention rate is a strong indicator of customer satisfaction and loyalty.
  • Higher customer retention rates indicate lower customer acquisition costs and increased revenue.
  • It helps identify potential customer experience and satisfaction issues and, thus, provides an opportunity to address them proactively.

KPI Disadvantages

  • A high customer retention rate does not necessarily mean a low churn rate.
  • Factors outside the restaurant's control, such as a change in the customer's financial situation, can affect the customer retention rate.
  • Ignoring other critical metrics such as customer satisfaction and repeat visits can adversely impact customer retention rates.

Industry Benchmarks

According to a study by LoyaltyOne, the average customer retention rate in the foodservice industry is 26%.

Tips & Tricks:

  • Track customer retention rate over multiple periods, such as weekly, monthly, or even annually, to determine trends and make informed business decisions.
  • Improve customer retention rates by using customer feedback to identify pain points and implementing changes to address them.
  • Implement customer loyalty programs, such as discounts or free meals, to reward repeat customers and boost customer retention rates.

Food Cost Percentage

Definition: Food cost percentage represents the cost of ingredients used to prepare menu items divided by the revenue generated from the sale of those menu items.

Use Case: Food cost percentage is a critical metric for sushi restaurants because it reflects the profitability and efficiency of their food operations. By tracking this KPI, sushi restaurant owners and managers can identify potential issues with their food costs and make data-driven decisions to maximize profits.

How To Calculate KPI:

Food Cost Percentage = (Total Cost of Ingredients / Total Menu Sales) x 100

Calculation Example:

Food Cost Percentage = ($5,000 Total Cost of Ingredients / $20,000 Total Menu Sales) x 100 = 25%

KPI Advantages:

Top Seven Sushi Restaurant KPI Metrics: How to Track and Calculate

Gross Profit Margin

Definition: Gross profit margin is a financial indicator that measures how efficiently a sushi restaurant generates revenue from selling sushi, net of the cost of goods sold needed to make the sushi.

Use Case: Gross profit margin is a crucial sushi restaurant KPI that helps determine profitability, pricing strategy, and operating efficiency.

How to Calculate KPI: Gross profit margin formula is:

Gross Profit Margin = ((Total Sales) - (Cost of Goods Sold))/(Total Sales) * 100

The cost of goods sold includes the direct costs associated with the production of sushi ingredients (rice, fish, vegetables, etc.) and other costs like packaging and utensils. Sales refer to the total revenue generated from selling sushi.

Calculation Example: Restaurant A has total sales of $50,000, cost of goods sold of $20,000, then the gross profit margin is:

Gross Profit Margin = (($50,000) - ($20,000))/(($50,000)) * 100 = 60%

KPI Advantages: Gross profit margin provides insight into the operational efficiency of the sushi restaurant by measuring how well the business controls its cost of goods sold. Effective margin management can help predict profitability and guide pricing strategies.

KPI Disadvantages: Gross profit margin does not consider operating costs like rent, marketing, payroll, and utilities, which are vital in running a sushi business. An increase in gross profit margin could indicate a cost-saving strategy, but it may also lead to revenue loss if the sushi restaurant hikes prices too high.

KPI Industry Benchmarks: The ideal gross profit margin for sushi restaurants is 60% or higher, according to industry benchmarks. However, depending on the geographical location and the sushi restaurant's size, the margin can vary significantly.

Tips & Tricks:

  • Track your gross profit margin regularly to gain insight into operational efficiency and pricing strategy.
  • Consider using cost-effective sushi materials and supplier discounts to lower your cost of goods sold.
  • Regularly review your prices to ensure they remain competitive and lead to optimal gross profit margins.

Net Promoter Score (NPS)

Definition: Net promoter score is a sushi restaurant KPI that measures customer loyalty based on willingness to recommend the sushi restaurant to others, typically on a 0-10 scale.

Use Case: NPS is essential in measuring customer satisfaction, loyalty, and how the sushi restaurant's reputation impacts future customer growth.

How to Calculate KPI: NPS is calculated as a subtraction of the percentage of customers considered detractors (scored between 0-6) from the percentage of customers considered promoters (scored between 9-10). The resulting score is between -100 and +100.

Net Promoter Score = % Promoters - % Detractors

Calculation Example: If 35% of customers are promoters, 20% are detractors, and 45% are passives, then the NPS is:

NPS = 35 - 20 = 15

KPI Advantages: NPS offers valuable insights into customer satisfaction and opinions. By tracking NPS, a sushi restaurant can improve service quality, address customer complaints, and increase customer retention, all of which are central to growth.

KPI Disadvantages: NPS measures customer opinion, but not necessarily behavior, which can lead to a lack of actionable data. Additionally, NPS does not consider customer demographics, like age or income, that could impact their scores.

KPI Industry Benchmarks: For sushi restaurants, the ideal NPS benchmark ranges from 30 to 70, although an NPS score of 50 is typically considered excellent.

Tips & Tricks:

  • Regularly monitor customer responses on social media, Yelp, or other review sites to keep track of feedback and identify areas of improvement.
  • Consider offering incentives to loyal customers to increase the likelihood of return customers.
  • Ensure customer-facing managers respond to customer complaints promptly and satisfactorily to prevent negative NPS scores.

Number of new customers per month


The number of new customers per month is a KPI that measures the number of first-time customers that visited your sushi restaurant in a given month.

Use Case

Tracking this KPI allows sushi restaurant owners and managers to gauge customer acquisition efforts and determine the effectiveness of marketing campaigns. It also enables a better understanding of seasonal trends, helps in forecasting business growth, and aids in identifying changes in consumer behavior over time.

How To Calculate KPI

To calculate the number of new customers per month, you can use the following formula:

Number of new customers per month = Total number of new customers in a given month

Calculation Example

Suppose your sushi restaurant opened in January and served 100 new customers that month. In February, there were 80 new customers, and in March, there were 60 new customers. The calculation for the number of new customers per month would be:

January: 100

February: 80

March: 60

Number of new customers per month = (100+80+60)/3

Number of new customers per month = 80

Therefore, the average number of new customers per month for the first quarter of operation is 80.

KPI Advantages

  • Helps track the success of customer acquisition efforts
  • Provides insights into seasonal trends and changes in consumer behavior over time
  • Informs forecasts for business growth

KPI Disadvantages

  Quality of Ingredients Rating = (Total Number of Positive Reviews for Ingredients / Total Number of Reviews for Ingredients) * 100

Calculation Example

Suppose a sushi restaurant has 100 online reviews for its ingredients, and 85 of those reviews are positive. The calculation for the quality of ingredients rating KPI would be:

  Quality of Ingredients Rating = (85 / 100) * 100 = 85%

KPI Advantages

  • Helps ensure consistent quality of ingredients
  • Improves customer satisfaction and loyalty
  • Increases revenue and profits

KPI Disadvantages

  • Dependent on customer reviews, which can be subjective
  • May not reflect the true quality of ingredients
  • Can be difficult to improve if there are constraints on ingredient quality

KPI Industry Benchmarks

According to industry benchmarks, the average quality of ingredients rating for sushi restaurants is around 80-85%. However, higher-end restaurants may aim for a rating of 90% or higher.

Tips & Tricks
