By understanding these KPIs and how to track and calculate them, you can make informed decisions to grow your dollar retail business. So let's dive in and see how to use these KPIs to measure your store's performance.

Average transaction size

Definition: Average transaction size refers to the average value of each transaction made in a retail store. This KPI provides insight into the purchasing behavior of customers and helps retailers understand how to optimize their sales strategies.

Use Case: By tracking average transaction size, retailers can identify trends in customer spending habits and tailor their marketing and sales efforts accordingly. For example, if the average transaction size is relatively low, retailers can develop promotions and upselling strategies to encourage customers to spend more per visit.

How To Calculate KPI: To calculate average transaction size, divide the total revenue generated by the number of transactions.

KPI Formula: Average Transaction Size = Total Revenue / Number of Transactions

Calculation Example: If a retail store generates $100,000 in revenue from 1,000 transactions, the average transaction size would be $100.

KPI Advantages:

  • Provides insight into customer buying habits
  • Helps retailers identify opportunities for increasing revenue
  • Can inform pricing and promotion strategies

KPI Disadvantages:

  • Can be skewed by outlier transactions (e.g. high-value purchases)
  • Does not provide information on individual customer behavior
  • May not be relevant for all types of retail businesses

KPI Industry Benchmarks: The average transaction size can vary widely depending on the industry and size of the retail store. According to a study by Square, the average transaction size for retail businesses in the United States is $84.

Tips & Tricks:

  • Encourage customers to add more items to their purchase through upselling strategies (e.g. 'Would you like to add a complimentary item to your purchase?')
  • Implement pricing strategies (e.g. product bundling) that incentivize customers to spend more per transaction
  • Offer loyalty programs that reward customers for spending more per visit

Inventory Turnover Rate

If you're running a retail store, one of the most important metrics you need to track is the inventory turnover rate. This KPI measures how many times you've sold and replaced your inventory in a given period, typically a year.


The inventory turnover rate is a measure of how efficiently a company is managing its inventory levels. It calculates how quickly a company is selling its inventory and how well it is managing the flow of new inventory into the business. A high inventory turnover rate indicates that a company is selling its products quickly and efficiently, while a low inventory turnover rate can indicate poor sales or excessive inventory levels.

Use Case

The inventory turnover rate is an important KPI for retail stores because it helps managers monitor the efficiency of inventory management. By tracking the turnover rate, managers can make more informed decisions about procurement, pricing, and sales strategies. They can identify slow-moving products that need to be marked down or discontinued and focus on promoting high-demand products. A healthy inventory turnover rate can help businesses maximize sales and profits while reducing storage and holding costs.

How To Calculate KPI

The inventory turnover rate is calculated by dividing the cost of goods sold (COGS) by the average inventory value during a period:

Inventory Turnover Rate = COGS / ((Beginning Inventory + Ending Inventory) / 2)

Calculation Example

Let's say your retail store had a COGS of $500,000 and the beginning inventory value was $100,000 while the ending inventory value was $150,000. The inventory turnover rate would be calculated like this:

Inventory Turnover Rate = $500,000 / (($100,000 + $150,000) / 2) = 2.22

So, your retail store had an inventory turnover rate of 2.22 for the given period.

KPI Advantages

  • Helps businesses identify slow-moving and fast-selling products
  • Helps in optimizing inventory levels to reduce holding costs
  • Enables better decision-making for procurement, pricing, and sales strategies

KPI Disadvantages

  • Does not take into account differences in profit margins between products
  • May not be a suitable KPI for specialty retail stores with unique products and longer shelf lives
  • Can be influenced by seasonal fluctuations in demand

KPI Industry Benchmarks

The inventory turnover rate can vary based on industry and company size. According to industry benchmarks, a retail store with a turnover rate of 2.0 is considered average, while a rate of 4.0 or above is considered excellent.

Tips & Tricks

  • Regularly track your inventory turnover rate to optimize inventory management
  • Consider using the ABC analysis method to identify your highest-margin and fastest-selling products
  • Use the inventory turnover rate to negotiate better pricing and terms with suppliers

Customer Retention Rate

One of the most important KPI metrics for any dollar retail store is customer retention rate. It measures the percentage of customers who continue to shop at your store over a certain period of time. This KPI is essential because it helps you understand how loyal your customers are, and how likely they are to return to your store.


Customer retention rate is the percentage of customers who continue to shop at your store over a certain period of time. It is calculated by dividing the number of retained customers by the number of total customers.

Use Case

The customer retention rate is used to measure the effectiveness of a dollar retail store's marketing and customer service strategies. By knowing the percentage of customers who continue to shop at your store, you can gauge how effective your marketing and customer service are in keeping customers coming back. This KPI is also useful for identifying areas for improvement and optimizing your marketing and customer service strategies.

How To Calculate KPI

To calculate the customer retention rate KPI, you will need to follow two simple steps:

  • Step 1: Determine the period over which you want to measure customer retention. This could be a month, quarter, or year.
  • Step 2: Calculate the percentage of customers who continue to shop at your store over that period. To do this, divide the number of retained customers by the number of total customers and multiply by 100.

KPI Formula:

Customer Retention Rate = (Number of Retained Customers / Number of Total Customers) x 100

Calculation Example

Let's say you want to measure your store's customer retention rate for the month of January. Your store had 200 customers in January, and 150 of them returned to make a purchase in February.

Using the formula:

Customer Retention Rate = (150 / 200) x 100 = 75%

Therefore, your store's customer retention rate for January is 75%.

KPI Advantages

  • Helps gauge customer loyalty and the likelihood of returning customers
  • Useful in identifying areas for improvement and optimizing marketing and customer service strategies
  • Course of action can be taken in case of negative trend

KPI Disadvantages

  • Can be affected by outside factors like competitors
  • Does not account for the spending habits of individual customers
  • May not accurately reflect customer satisfaction

KPI Industry Benchmarks for 'Customer Retention Rate'

The average customer retention rate for dollar retail stores is around 60%. However, this can vary depending on the store's size, location, and customer demographics. Competitive analysis and self-analysis techniques can help gauge the adequacy of this KPI for specific retail stores.

Tips and Tricks:

  • Track customer feedback or experience survey as regular reviews to know what your customers love/hate about your retail store.
  • Focus on retaining potential loyal customers, and put extra effort into offering personalised recommendations and actions to show you care for them.
  • Keep an eye on your competitors' marketing strategy, and try enhancing your approach, not necessarily copying, to retain your customer base and attract new ones.

Gross profit margin

As a retail store owner, Gross profit margin is an essential KPI metric to measure your business's financial health. It is a profitability ratio that calculates the percentage of revenue left after deducting the cost of goods sold. To acquire the maximum benefit of gross profit margin analysis, businesses must track this metric regularly.


Gross Profit Margin (GPM) is the ratio of gross profit to total revenue, expressed as a percentage. Gross profit represents the difference between sales revenue and the cost of goods sold. It indicates how much profit the company is generating after directly accounting for the production of goods and services.

Use Case

Gross profit margin is a crucial KPI for retail stores as it helps to analyze gross profits per sale. The KPI's analysis helps in identifying the strengths and weaknesses of the item or product groups, allowing business owners to adjust pricing strategies and optimize the product mix. Business owners with multiple stores can compare and contrast sales performances, updating their product strategies as required.

How to Calculate KPI

To calculate Gross Profit Margin (GPM), you first need two financial metrics Gross Profit (GP) and Revenue (Rev).

GPM = (GP / Rev) x 100

Calculation Example

Suppose a retail store has made $100,000 in sales and has a cost of goods sold of $50,000. Therefore the gross profit is $50,000. This gives a Gross Profit Margin of:

GPM = ($50,000 / $100,000) x 100

GPM = 50%

KPI Advantages

  • Gross Profit Margin offers a straightforward and reliable indication of a business's financial performance
  • It enables the comparison of a company's performance against industry or sector benchmarks
  • Gross Profit Margin is effective in measuring profit and assessing the effectiveness of the pricing strategy.

KPI Disadvantages

  • Gross Profit Margin does not account for indirect expenses such as fixed costs
  • This profitability ratio only considers the cost of production and neglects the indirect business expenses like overhead costs, utilities, taxes, and advertising expenses.
  • Gross Profit Margin analysis cannot determine whether a company is over or undercharging for goods or services.

KPI Industry Benchmarks

Industry benchmarks for Gross Profit Margin vary across retail sectors. For instance, the average Gross Profit Margin of a grocery or convenience store ranges from 22% to 25%. On the other hand, the margin for apparel stores ranges from 37% to 40%. Industry benchmarks change over time based on macro-economic factors and new industry entrants' arrival. Therefore, it is essential to track and correlate your Gross Profit Margin with the industry benchmark values.

Tips & Tricks

  • Having a better Gross Profit Margin means efficient management of purchasing and inventory costs.
  • Constantly benchmark your profitability ratios and compare them with other industry players.
  • The Gross Profit Margin is best used in conjunction with other KPI metrics (e.g., Net Profit Margin or Operating Expense Ratio) to provide a complete picture of the business's overall profitability.

Sales growth rate

The sales growth rate is a crucial KPI that measures the percentage increase or decrease in revenue generated by a retail store over a certain period of time.


The sales growth rate KPI measures the increase or decrease in the retail store's revenue during a specific period of time. This KPI is an important metric to monitor since it indicates trends in the store's sales performance.

Use Case

The sales growth rate KPI can be used by retail managers to track the sales performance of their stores. It can also help them identify any potential issues that may be impacting their sales growth and take necessary actions to address them.

How To Calculate KPI

To calculate the sales growth rate KPI, use the following formula:

(Total Revenue for Current Period - Total Revenue for Previous Period) / Total Revenue for Previous Period

Calculation Example

Let's say a retail store made $50,000 last year and $60,000 this year. The sales growth rate KPI would be:

($60,000 - $50,000) / $50,000 = 0.2 or 20%

KPI Advantages

  • Helps identify sales trends
  • Allows for quick comparison of sales performance between periods
  • Helps managers make informed decisions about pricing, promotions, and inventory management

KPI Disadvantages

  • Does not indicate the reasons behind the increase or decrease in sales
  • May not be accurate in certain situations, such as when stores change their product mix
  • Does not account for inflation or changes in the market

KPI Industry Benchmarks

The sales growth rate benchmark varies by the retail industry. According to the National Retail Federation in 2020, the average sales growth rate for the US retail industry was 2.8%.

3 Tips for Improving Sales Growth Rate:

  • Regularly review your sales performance to identify trends and areas for improvement
  • Develop marketing strategies that target new customers and increase sales from existing customers
  • Regularly analyze data to understand customer buying behaviors and preferences

Number of new customers acquired

As a retail store owner, it's crucial to track the number of new customers acquired to measure your business's growth. In this section, we will discuss:


Number of new customers acquired refers to the number of first-time customers who have made a purchase at your store within a specific timeframe.

Use Case

Tracking the number of new customers acquired is a valuable KPI metric for retail stores to measure their overall performance. This KPI helps to identify trends, patterns, and opportunities for growth in the business.

How To Calculate KPI

The formula to calculate the number of new customers acquired is:

Number of new customers acquired = Total number of new customers in a given time period

Calculation Example

Let's say you've opened a new store in January and want to track the number of new customers acquired over the next three months. You record all first-time customers during that period, and here's what you have:

Number of new customers acquired = 100

KPI Advantages

  • Allows for the identification of growth opportunities
  • Helps to measure the effectiveness of marketing strategies
  • Provides insight into customer behavior and preferences

KPI Disadvantages

  • May not account for repeat customers
  • Doesn't measure customer loyalty
  • Doesn't take into account the value of customer purchases

KPI Industry Benchmarks

The industry benchmarks for the number of new customers acquired vary depending on the sector. However, in the retail industry, a growth rate of 5% to 7% is considered healthy.

Tips & Tricks

  • Use customer feedback to improve the shopping experience to attract new customers.
  • Provide incentive programs targeted at new customers to encourage repeat visits.
  • Track your KPIs frequently and adjust strategies as necessary.

Employee Productivity Rate

Employee productivity rate is a crucial metric for measuring the productivity of an organization. It sets the pace for the organization's overall performance. It provides insights into how much each employee is contributing to the company's success and how efficient the employees are at their work.


The employee productivity rate is defined as a measure of the output of an employee within a given time frame. It is a calculation of the ratio of an employee's output to the input required to produce that output.

Use Case

Employee productivity rate is essential in retail stores since it allows management to spot any inefficiencies or gaps in the workforce. A high productivity rate indicates that all employees are doing their job correctly, which leads to better customer satisfaction, increased revenue, and higher profit margins.

How To Calculate KPI

To calculate the employee productivity rate, you need to divide the total number of output by the number of hours worked.

Employee Productivity Rate = Total Output / Number of Hours Worked

Calculation Example

Suppose a retail store generated $500,000 in revenue in a month, and the total number of hours worked by the staff was 3000. In that case, the employee productivity rate would be:

Employee Productivity Rate = $500,000 / 3000

Employee Productivity Rate = $166.67 per hour

KPI Advantages

  • Helps identify the most productive and efficient employees in the store.
  • Helps identify areas that need improvement, and the retail store can implement training programs to improve employee performance.
  • Helps identify factors negatively impacting productivity, such as a shortage of staff, lack of resources, or inefficient processes.

KPI Disadvantages

  • This KPI does not take into account the quality of the output generated by the employees. A high productivity rate does not necessarily mean high-quality work.
  • It may not accurately reflect the productivity of the retail store if the output or number of hours worked is affected by external factors such as weather conditions, traffic, or inventory issues.

KPI Industry Benchmarks

The employee productivity rate varies significantly by the type of retail store. For instance, a grocery store might have an employee productivity rate of $150 per hour, while a department store might have a rate of $200 per hour.

Tips & Tricks

  • Implement a reward system for employees who consistently maintain a high productivity rate to motivate other employees.
  • Review the employee productivity rate regularly to ensure that all employees are productive, and if not, implement corrective measures promptly.
  • Provide employees with additional resources or modern tools to help them work faster and more efficiently.
