9 Grocery Store KPIs Every Store Owner Should Track

You know that running a successful grocery store involves more than just stocking shelves and ringing up sales. To succeed, you need a deep understanding of your sales, performance, and margins. 

That's where key performance indicators (KPIs) come in.

Tracking the right KPIs gives you valuable insights into your store's strengths and weaknesses. You can identify areas that need improvement, understand your customers' shopping habits, and make better decisions based on accurate data. KPIs turn grocery store management from guesswork into a science.

But with so many metrics, it can be overwhelming to know where to start.

That's why we've compiled a list of nine critical KPIs every grocery store owner should track. We’ll also share tips for tracking them so you can make better business decisions and keep your customers happy.

Let’s examine some of the critical benefits of tracking KPIs for your grocery store: 

• Identify and address weak areas in your store: By tracking KPIs, you can pinpoint areas of your business that may be underperforming, such as low-selling products or inefficient processes. 
  
  
• See how customers are shopping and what they want: KPIs can provide valuable insights into customer behavior, preferences, and trends. Analyzing metrics like average basket size, customer loyalty, and product popularity helps you understand your customers and better stock your store to serve their needs. 
  
  
• Make decisions based on facts, not guesses: Tracking KPIs removes the guesswork from decision making. Instead of relying on intuition or assumptions, you can base your strategies on concrete data.
  
  
• See whether changes you've already made are working: Implementing new strategies or initiatives is only half the battle; you also need to know if they're actually working.
  
  
• Keep inventory at the right levels: Effective inventory management is essential for minimizing waste, avoiding stockouts, and optimizing cash flow. Tracking inventory-related KPIs helps you stock the right products in the right quantities, reducing the risk of lost sales or spoilage.
  
  
• Identify and resolve issues that frustrate customers: KPIs can illuminate common pain points that may drive customers away, such as long checkout lines, poor product availability, or unsatisfactory service. 
  
  

Now that we've established why tracking KPIs is so essential, let's explore the top metrics you need to understand to improve your grocery store's performance. 

1. Sales Per Customer

Sales per customer is a critical KPI that helps you analyze customer spending and average transaction size. You can use this metric to understand what people are buying and when. This data can help you identify opportunities to boost your average basket size and drive additional revenue. 

Sales per customer can also help you create targeted promotions and rewards programs that incentivize customers to purchase more items during each visit.

Benchmark: The average sales per customer in the grocery industry ranges from $20 to $50, depending on factors like store size, location, and target market.

How to track it:

• Use your POS system to break down sales per customer by segment, such as customer demographic, store location, or period.
• Analyze the data to identify trends and patterns in customer spending behavior.
• Monitor the effectiveness of promotional campaigns and store layout changes by measuring their impact on sales per customer.

Sales Per Customer = Total SalesNumber of Customers

2. Customer Retention Rate

Customer retention rate is another KPI you should track for your grocery store. This metric measures customer loyalty and helps identify repeat customers. You can improve customer retention rates by focusing your marketing efforts on cultivating customer loyalty and increasing visit frequency.

Benchmark: A reasonable customer retention rate in the grocery industry is around 80% or higher, meaning that 8 out of 10 customers continue to shop at your store over a given period.

How to track it:

• Calculate the percentage of customers who shop multiple times over a year by dividing the number of repeat customers by the total number of customers.
• Use a loyalty program to track customer purchase history and visit frequency, providing valuable insights into retention rates.
• Segment customers based on their retention rates and target them with personalized offers and promotions to encourage repeat visits.

Customer Retention Rate = (# Customers at Period End- # Customers at Period Start)# Customers at Period Start

3. Average Inventory Turnover

Average inventory turnover is a crucial KPI that identifies stagnant merchandise and helps retailers optimize buying levels. Ensuring that your inventory is fresh and aligns with customer demand can minimize holding costs, improve cash flow, and reduce the risk of spoilage, which is especially critical for stores with lots of perishable inventory.

This metric also guides your purchasing decisions, helping you strike the right balance between product availability and operational efficiency.

Benchmark: The average inventory turnover rate in the grocery industry is around 15-20 times per year, meaning that a store sells through its entire inventory every 2-3 weeks.

How to track it:

• Divide the total cost of goods sold by the average inventory level over a given period to calculate the inventory turnover rate.
• Calculate turnover rates by department or product category to identify areas of improvement and optimize your product mix.
• Use a POS system to monitor sales and inventory levels in real time, enabling you to make data-driven decisions and adjust your strategies accordingly.

4. Inventory Accuracy

How accurate are your inventory counts? Your inventory accuracy is critical to minimizing waste and improving purchasing decisions.

When your inventory data matches your physical stock levels, you can more accurately forecast demand, prevent stockouts or overstocking, and optimize your supply chain. 

Benchmark: The industry best practice for inventory accuracy is 95% or higher, meaning that your system records should match physical counts for at least 95% of your products.

How to track it:

• Conduct regular cycle counts and compare manual counts to system levels to identify discrepancies and maintain accuracy.
• Implement quality control measures and system discipline to record all inventory transactions accurately and on time.
• Use barcode scanning and automated inventory management tools to minimize human error and streamline the tracking process.

5. Email Campaign Conversion Rate

Your email campaign conversion rate measures the effectiveness of your marketing efforts and helps you optimize your return on investment (ROI). 

Analyzing the performance of your email campaigns helps you refine your content, subject lines, and timing to maximize engagement and drive sales. This KPI also identifies your top-performing campaigns and product categories, guiding future promotions.

Benchmark: The average email campaign conversion rate in the grocery industry is around 2-5%, meaning that 2-5% of recipients purchase as a result of the email.

How to track it:

• To calculate the conversion rate, divide the total sales attributable to an email campaign by the number of messages sent.
• Monitor each campaign's open, click-through, and conversion rates to identify areas for improvement and optimize your email marketing strategies.
• Test different email elements, such as subject lines, content, and call-to-actions, and analyze historical performance to refine your approach and maximize conversions.

Email Campaign Conversion Rate = # Conversions # Emails Sent

6. Average Checkout Speed

Average checkout speed is a critical KPI that ensures an efficient checkout process and minimizes customer wait times. Speeding up checkout can help you improve customer satisfaction and reduce cart abandonment rates. 

Having a finger on the pulse of this metric will also help you optimize staffing levels and checkout lane configurations to maximize efficiency.

Benchmark: The industry standard for average checkout speed is around 2-3 minutes per customer, with top-performing stores achieving even faster times.

How to track it:

• Measure the time it takes for the average customer to get through checkout lines, from the moment they enter the queue to the completion of the transaction.
• Set targets for cashiers to ring up 15-25 guests per hour, depending on the complexity of the transactions and the store's layout.
• Implement modern solutions like self-checkout kiosks and express lanes to speed up the process and provide customers with more options.
  
  

7. Product Margin by Category

Product margin by category identifies the profitability of different product groups within your store. By analyzing category-level margins, you can optimize your sales mix and focus on high-margin items that drive profitability. 

This metric also guides your pricing, promotion, and inventory decisions, helping you allocate resources effectively.

Benchmark: The average product margin in the grocery industry ranges from 20-35%, depending on the category and the store's pricing strategy.

How to track it:

• Calculate category-level profitability by subtracting the cost of goods sold from sales revenue for each product group.
• Analyze margin trends over time and compare them against industry benchmarks to identify areas of improvement and set realistic targets.
• Adjust your pricing, promotion, and inventory strategies based on margin performance, focusing on high-margin categories and optimizing low-margin ones.

8. Inventory Days on Hand

Days on hand is a KPI that measures the number of days of average sales of your full inventory you have on hand at any given time. This KPI helps you optimize your inventory planning around order sizes and safety stock minimums. 

By balancing product availability with the risk of spoilage or obsolescence, you can optimize your inventory levels and improve turnover. This metric also helps you identify opportunities to streamline your supply chain and reduce holding costs.

Benchmark: The average inventory days on hand in the grocery industry is around 15-30 days, depending on the product category and the store's sales volume.

How to track it:

• Calculate the average shelf life per product category based on sales velocity and perishability, considering factors like expiration dates and seasonal demand.
• Use a POS system to monitor inventory levels and days on hand in real time, helping you make data-driven decisions and adjust your strategies accordingly.
• Adjust ordering frequencies and quantities based on historical data and seasonal trends to ensure you have the right products in the right quantities at the right time.

9. Gross Margin by Product

Finally, you’ll want to track gross margin by product. This KPI provides visibility into the profitability of each inventory item. By analyzing product-level margins, you can identify top-performing and underperforming products, guiding your pricing, promotion, and assortment decisions. 

This metric also helps you optimize your overall margins and maximize profitability at the store level.

Benchmark: The average gross margin by product in the grocery industry ranges from 10% to 50%, depending on the product category and the store's pricing strategy.

How to track it:

• Use a POS system to track gross margins by automatically recording sales revenue and cost of goods sold per unit.
• Analyze margin trends over time and compare against category averages to identify areas of improvement and set realistic targets.
• Adjust your sales strategies based on product-level margin performance, focusing on high-margin items and optimizing low-margin ones through pricing, promotion, or assortment changes.
