Using Retail Analytics & Top Retail Metrics to Drive Sales

Retail data analytics is the measuring, tracking, and interpretation of data that typically includes sales, inventory, employee, and consumer demand information. As retailers shift to more online sales in the wake of COVID-19, retailing analysis can be an effective way to increase revenue.

Below, we highlight how to analyze data in your store, the top 11 metrics you should be tracking, and how to use them to drive sales.

How to Use Retail Data Analysis

Retail analytics can be a powerful tool for driving sales, but to use them effectively, you’ll need to collect, examine, and interpret the analytics methodically. The hardest part about using retail analytics is not just making sure you have the data available, but knowing how to read it and how to turn that data into action.

Here is how retail analytics work in five steps:

1. Set up a POS System

Technically, it is possible to track some retail data analytics on your own with a spreadsheet. However, setting up a POS system can ensure accuracy while saving you hours of labor each week and providing complete information that can be collected manually. For that reason, the first step in implementing retail data analytics is to choose a POS system that can create custom reports that make valuable data easier to digest.

2. Choose What to Measure

Before you can use retail analytics to drive sales, decide what data points or performance metrics you want to measure. If you’re using a POS system, you’ll have a huge volume of information at your fingertips all at once. However, it’s best to focus on a few retail data points at a time and methodically measure a few small changes—instead of trying to track several variables at once and getting overwhelmed. We walk through key retail metrics and how to use them below.

3. Collect Retail Business Data

Once you choose specific metrics, start collecting that data. Data collection is where POS software will become your best friend. Many independent retailers try to track sales and customer transactions with spreadsheets. However, this takes a lot of time and manpower and never yields as much information as a POS provides. Plus, if your business is online, you’ll be able to access everything you need from your existing ecommerce dashboard.

4. Analyze and Compare Numbers

Having these numbers alone can provide some initial insight into your business’ performance. But to use these numbers to drive sales, you’ll need to plug them into one of the specific retail data analytics formulas below to get a more specific and actionable number. Then, create a set schedule for measuring your chosen analytics so you can track performance over time to see if sales are improving.

5. Use Retail Analytics to Inform Decisions

Once you determine what to measure and when, use the information you collect to inform business decisions. For example, if you’re collecting data around sales of specific product categories, see which categories are performing best. When it is time to buy merchandise, invest more in the product categories that have higher sales.

Top Retail Metrics for Small Businesses

There are dozens of specific retail analytics that business owners can use to evaluate performance, monitor progress, and—most importantly—drive sales. Many of these metrics can be used for online or brick and mortar businesses, but with the bulk of sales moving online, we’ll provide some helpful insight into how you can use data in an ecommerce or multichannel retail setting.

Here are the top 11 retail data metrics to drive sales and how to use them:

1. Average Transaction Value

Average transaction value (ATV) is the typical amount a customer spends when they shop with you. This is an accessible metric for both brick and mortar and online stores because most POS systems can provide the ATV on a daily, weekly, monthly, or annual basis. Measuring larger time frames provides a more accurate ATV, but monitoring daily ATV can help coach and encourage employees at the moment.

To calculate your average transaction, divide the total value of all transactions by the number of transactions. For example, if your monthly sales total $50,000 and you had 500 sales, your average sale is $100.

How to Use Average Transaction Value to Increase Sales

The only way to increase sales is to increase your number of customers or how much they spend. ATV gives you a snapshot of how much your current customers are spending so you can set strategies to increase that number. Businesses can use ATV to increase sales by:

• Building customer promotions to boost ATV: Using a gift with purchase promotion or discount with a certain dollar spend encourages customers to spend more to qualify for the promotion. Plus, this strategy is easy to employ even if you’ve moved your sales online.
• Upselling: Upselling is the process of educating customers on the features and benefits of purchasing a higher-end model of a product they’re interested in—and encouraging them to buy the pricier model. This can be accomplished online by recommending relevant upgrades or including a comparison table on individual product pages.
• Identifying top-performing employees: Brick and mortar businesses can measure employee-specific ATV to identify employees with the highest average transactions, and employees who need additional sales training.
• Setting specific ATV goals: Set a specific ATV that you would like employees to meet each shift or each week and consider offering a bonus for employees who meet their goals.

2. Items Per Purchase

Items per purchase, also sometimes called units per transaction (UPT), measures the average number of products sold during a customer transaction in a specific time period. So, while UPT is a similar concept to ATV, you’re measuring how many products customers buy on average instead of measuring how much customers spend on average.

Items per purchase can be calculated by dividing the total number of products sold by the total number of customer transactions for a specific time period. For example, if you have sold 100 items in 50 sales, your average items per purchase is two.

Like with ATV, you can use any length of time when measuring items per purchase. Monthly or seasonal data on items per purchase can provide a big-picture benchmark for how much people are buying. Daily or weekly UPT measurements can be used to track employee performance.

How to Use Items Per Purchase to Drive Sales

The most common way to increase items per purchase is via cross-selling, impulse sales, and add-on sales techniques. Cross-selling and add-on sales encourage customers to purchase additional related items. Impulse sales involve encouraging customers to make unplanned purchases.

Use cross-selling and add-ons to drive sales by:

• Strategically merchandising: Ever notice how during the summer, grocery stores will place marshmallows and graham crackers next to the chocolate? Retailers place lower demand items next to products with a higher draw to encourage extra sales. Recreate this in your online shop by including automated product recommendations based on individual products—or even consumer data.
• Training sales staff: Let employees know your current items per transaction, what you would like it to be, and educate them on all product offerings to help them make helpful recommendations to customers.

Increase items per purchase with impulse buys by:

• Merchandising your checkout: Place tempting items like treats, travel-sized products, or inexpensive necessities at checkout so customers can pick up extra items while waiting in line. Though checkout looks different online, some retailers accomplish this by including suggested items on the cart screen or using popups at checkout—both of which can be tailored to customer interests.
• Offering seasonal products: Seasonal products can mean anything from sunglasses in the summer to peppermint-flavored items around Christmas. Think about products that customers need or want during a specific time of the year and put them front and center—whether that’s on an eye-catching display or on your store’s homepage.

3. Market Basket Analysis

Market basket analysis (MBA) is a type of statistical affinity analysis that lets business owners determine the strength of association between certain products that customers purchase together. Using data collected through a POS system or other ecommerce tool, retailers can better predict the purchasing habits of customers—and ultimately drive sales.

Like measuring items per purchase, brands can use sales data to create likely conditions—or if-then statements—that let them anticipate which products a customer will buy. They can then use that information to recommend those products and increase sales. To do so, retailers use their existing POS system to collect sale data and then apply the Apriori algorithm, which can be used as part of the arules package in R.

Admittedly, this is a complex metric, so if you’re a smaller retailer, you may want to start by reviewing your sales data manually and making note of any patterns that stand out to you. For example, if you have an electronics store, you may find that customers who buy a new cellphone are more likely to also buy a screen protector and phone charger.

How to Use Market Basket Analysis to Drive Sales

Once you identify these relationships, the insight can be applied in both brick and mortar and online stores—similar to the ways you use UPT data. Increase your sales by:

• Cross-selling: If you can anticipate what customers are likely to reach for next, you can make it easier by placing those items close together in your store. In an online setting, create popups that appear when customers add certain items to their cart, include a “Discover Additional Products” feature like Amazon’s, or simply add likely pairings to product descriptions.
• Recommending related products: Likewise, having a better understanding of what customers are likely to put in their carts makes it easier to choose recommended products to place on individual product pages. If you have a brick and mortar store, this is also excellent insight to provide employees who can then make tailored recommendations to shoppers.
• Tailoring marketing promotions: Beyond your website or storefront, MBA data can help you craft more effective marketing campaigns. By knowing what customers want before they do, you can increase sales by creating specific, targeted ads that make it convenient for consumers to get everything they need in one place.

4. Conversion Rate

Retail conversion rate compares the number of people who enter your store or visit your website with the number of people who make a purchase. Perhaps surprisingly, average brick and mortar conversion rates range from 20% to 30%—so 70% to 80% of people who walk into your shop leave without buying anything. For ecommerce sites, the numbers are even more staggering, with conversion rates typically between just 1% and 3%.

Calculate your conversion rate by taking the total number of people who made a purchase and dividing it by the total number of visitors you have to your store or website. Conversion rate is presented as a percentage, so multiply by 100. For example, if 100 people walked into your store and 25 made a purchase, your conversion rate would be 25%.

How to Use Conversion Rate to Drive Sales

Conversion rate is more commonly used by online businesses because it’s easy to track how many people visit or view your site in any given time period. However, if you have a brick and mortar store, many POS systems connect with small business foot-traffic counters like Dor. Once it’s collected, use conversion rate data to increase sales by:

• Placing products on your ecommerce homepage: If your ecommerce site has lots of visitors who leave right away, it could be because the product they wanted was too hard to find. Make sure your promotions and advertisements bring shoppers directly to that product page and not your site’s homepage.
• Testing different product pricing: If many people are showing interest in your products but not purchasing, try testing different pricing promotions or slightly lowering prices to see if that increases conversions. This is even easier in an online setting because you won’t have to create new signage or price tags.
• Adding employees during times of low conversion rates: If your business has high foot traffic but low conversions, it may be a sign that customers aren’t getting the help or attention they need. Adding employees can increase sales and conversions. For online businesses, a chatbot can answer questions and help your customers find what they need faster.

5. Cart Abandon Rate

Cart abandon rate is the percentage of online shoppers who place items in their shopping cart but leave the site before purchasing, essentially abandoning their virtual cart. With online conversion rates so low, it makes sense that the average cart abandon rate is around 70%.

To calculate your website’s cart abandon rate, divide the number of completed transactions by the total number of shopping carts that have at least one item in them. Cart abandon rate is typically expressed as a percentage, so then multiply by 100. This number will give you the percent of completed transactions. Subtract this number to get the percent of abandoned transactions.

For example, if in one month you have 50 completed transactions, but 200 total shopping carts created, your completed transaction rate is 25%. So, your cart abandon rate is 75%.

How to Use Cart Abandon Rate to Drive Sales

Targeting a potential shopper based on their abandoned cart is extremely effective for increasing sales because you’re reaching out to someone who has already expressed interest in a product. Use cart abandonment data to increase sales with:

• Automated follow-up emails: After a shopper abandons their cart, follow up with personalized emails reminding them of what is in their cart.
• Discounts or promotions: Consider sending a 15% or 20% coupon to be used on the items in the shopper’s abandoned cart.

In addition to targeting shoppers who already abandoned their carts, you can reduce your overall cart abandon rate by encouraging shoppers to purchase right away. Ecommerce sellers can drive sales and reduce cart abandonment by:

• Showing the total cost of order: Shoppers are often surprised by the total cost of their order after shipping, taxes, and other fees are calculated. Prevent this by showing the estimated total with these fees included before shoppers even hit the checkout button.
• Reducing shipping costs: Oftentimes, shipping costs prevent shoppers from placing an order. Combat this by offering free shipping with a minimum purchase so shipping fees don’t eat into your margins but shoppers don’t abandon their carts.
• Streamlining checkout: Shoppers abandon carts when there are too many steps to take—or too much information to type—during checkout. Make it easier for customers to complete a sale by offering guest checkout and easy payment options like Apple Pay and PayPal.
• Having an agreeable return policy: Some shoppers abandon their cart if they are not sure what the return policy is, or if they’re worried they won’t be able to return the item at all. By clearly posting a consumer-friendly return policy, you’ll set these shoppers at ease.

6. Sell-Through Rate

Sell-through rate is the percentage of an individual product sold during a certain time frame. It looks at how many of a particular item you started with and how many are left at the end. To calculate sell-through rate, divide the number of products sold by the beginning inventory on-hand.

For example, if you bought 100 copies of a specific book to sell in your store and after one month 40 of those books had sold, your sell-through rate would be 40%.

How to Use Sell-Through Rate to Drive Sales

Retailers can use the sell-through rate to determine the popularity of certain products or the success of a new product launch. This enables online, brick and mortar, and multichannel businesses to increase sales by:

• Knowing when to purchase products: By knowing how quickly products are selling, you can tell which to purchase more frequently—and you won’t miss out on sales by running out of inventory. If your store is exclusively online, this strategy can also help you avoid storing products when they’re less likely to sell.
• Showcasing bestselling products: Prominently displaying products with the fastest sell-through rates and labeling them as “bestsellers” increases sales by encouraging more shoppers to purchase the product. For online retailers, this can be accomplished by highlighting products on your store’s homepage—or as recommended items at the bottom of relevant product pages.
• Discounting slow-moving merchandise: Decreasing the price of products with slower sell-through rates can increase sales of those products. This approach is even easier if you have an ecommerce business—simply adjust pricing online and gauge customer response.
• Eliminating worst-selling products: Phase out slow-moving products and increase sales by making room for new merchandise or bestselling items. This is also a smart strategy if you’re short on space for storing inventory.

7. Sales Per Category

Sales per category—or sales per department—examines the total sales a retailer has for each type of product. This information is useful because it shows which types of products are bringing in the most money. With deeper insight, it can also be used to determine the most popular and profitable product categories so you can drive additional retail sales.

Luckily, sales per category is one metric that requires very little calculation. It just involves tracking product sales and totaling those numbers based on whatever categories you choose. If you’re using a POS system, sales per category numbers are automatically calculated.

If you’re not using a POS system, the ability to track sales per category comes down to the tools you use to organize your inventory. For example, if you’re using a separate inventory management software, you could track estimated category sales with inventory counts. Some retailers even track category sales with spreadsheets that they update at the end of each day, although this can be quite labor-intensive.

Using Category Data to Increase Retail Sales

Sales per-category data allows you to make informed decisions on which products to feature in your store, which products to restock, and which ones are not selling. Accomplish this by:

• Focusing on what’s working: If one or a few categories are consistently outselling others, feature those items more prominently in displays and on your website. If you have room in your stockroom or warehouse, consider expanding product lines in those categories.
• Investing in profitable merchandise: When it comes time to restock products or introduce new merchandise, buy more products in the categories that are selling well. This will be especially helpful if you have an online shop and can’t store inventory for long periods of time.
• Phasing out slow categories: If there are categories that are selling significantly less than others, consider making them a smaller part of your store, especially if those current products take up a large footprint in your storefront or storage area.

8. Gross Margin

Gross margin is an important data analytic point for driving retail sales because it shows what percentage of your store or product revenue is actually profit—versus what just covers the cost of merchandise. Products with higher profit margins can be more profitable than items that have higher total sales, but a lower profit margin.

Gross margin is calculated by subtracting the cost of goods sold (COGS) from revenue, dividing by revenue, and then multiplying by 100 to get a percentage.

For example, let’s say you have a sweater that you sell for $50 and it costs you $15 to purchase that sweater wholesale. Your gross margin would be 70%, which is pretty good. Margins can vary by industry (grocers and food sellers typically have lower margins), but generally retailers should aim for at least 50% margins.

How to Use Gross Margin to Drive Sales

Gross margin can be calculated for the entire store, per item, or per product category. Once determined, retailers can use gross margin to increase sales by:

• Increasing prices on low-margin products: If some of your margins are very low (below 40%) try increasing them slightly. Ecommerce makes it extremely easy to experiment with pricing because you don’t have to constantly change physical price tags or signage.
• Stocking more high-margin products: Because you make a higher percentage of profit from each sale, high margin products bring in more profit even if sales are slower than for low-margin products. Depending on your warehouse situation, though, this may be difficult for ecommerce businesses—especially if you recently moved online.
• Promoting high-margin products: Change your store display to feature high-margin products in the front or at checkout. Likewise, an online business can feature high-margin products on its homepage or in email promotions.

9. Customer Retention in Retail

Customer retention rate refers to a retailer’s ability to hold on to current customers and keep them coming back. High customer retention rates typically indicate strong customer loyalty and strong customer satisfaction with the retailer’s products and customer service. These numbers are perhaps more important now than ever as retailers are testing new ways to retain customers during a pandemic.

To calculate customer retention rate divide the total of repeat customers by the number of total customers. Retention rate is typically expressed as a percentage, so then multiply that by 100. For example, if you have 500 total customers one month, and 200 of those are repeat customers, your retention rate is 40%.

How Customer Retention Rate Drives Sales

Customer retention rate is important for sales because it focuses on long-term revenue and growth potential. If a business consistently brings in new customers, but they only shop once, your sales will remain steady but won’t grow in a significant way. Alternatively, if it brings in new customers who keep returning, that business will experience a lot of growth.

Customer retention also leads to higher sales in less concrete ways, including:

• More referrals: Loyal or regular customers are more likely to spread positive feedback about your business and recommend your business to friends or family. This is especially powerful for ecommerce businesses that aren’t limited by customer location.
• Decreased cost of customer acquisition: It costs 25% more to acquire new customers than to retain current ones. If you’re relying on Facebook Ads or other online marketing to drive traffic to your website, this is an especially important statistic.
• Higher spending: Customers who return to your store again and again typically have a higher average transaction value than first-time customers.

10. Sales Per Square Foot

Sales per square foot is the average revenue your store brings in for every foot of sales space. To calculate your sales per square foot, take your total sales, and divide by the number of square feet in your selling area. The selling area consists of the sales floor, merchandise displays, and register area—just don’t count your office or stockroom.

For example, if you have sold $500,000 worth of merchandise in a year and the total area of your sales floor is 2,000 square feet, your sales per square foot is $250.

Retailers should aim for at least $500 per square foot in annual sales, but this can vary depending on your merchandise. If you sell bulky, inexpensive products, like second hand furniture, your sales per square foot is likely lower than that of a high-end electronics store. That said, if your sales per square foot are significantly lower, they may be lower than they should be.

How to Use Sales Per Square Foot to Drive Sales

Sales per square foot serve as a guide or score for your visual merchandising and retail store layout. Unfortunately, sales per square foot doesn’t really translate to ecommerce so it may not be a helpful metric in the shifting retail landscape. If you have a brick and mortar shop, use sales per square foot to increase sales by:

• Comparing sales per square foot for different areas of the store: If certain areas of your store have higher sales per square feet, try to replicate those merchandising strategies or product selections in underperforming store areas.
• Changing your store layout: If all of your bestselling items are at the front of your store, shoppers might not even be looking at the back half; switch your layout to encourage shoppers to walk around the whole space.

11. Sales Per Employee

Sales per employee examines how much revenue each employee is bringing in. Retailers can look at total sales by employee, but a more accurate method is examining an employee’s average retail sales per hour because it fairly compares full time and part-time workers.

To calculate the average sales per employee per hour, first gather the total sales by each employee. Take each employee’s individual sales and subtract any commissions they receive from those sales. Finally, divide that number by the number of hours they worked. This will give you their average sales per hour.

POS systems automatically show employees’ sales per shift or per day. Many systems, like Lightspeed, also let businesses run custom reports on employee sales to see metrics like average sales per hour, sales per category, and sales per time of day.

How to Drive Sales With Employee Data

Examining employees’ average sales per hour provides insight into current performance and provides a benchmark for what retailers can expect employees to accomplish. Average sales per employee data can be used to drive sales by:

• Informing staffing decisions: If you want to hit a particular revenue goal, this data point will help you determine how many employee hours you will need to hit that goal.
• Spot coaching opportunities: If some employees have an average sales per hour that is much lower than others, they may benefit from sales training to help boost their performance.
• Identify strengths: If some employees have high average sales per hour, retailers can monitor those employees, evaluate what they’re doing that’s causing them to perform well, and share that information with the team.

Bottom Line

Now more than ever, business owners need targeted data to make purchasing, marketing, and staffing decisions that will increase profitability—without the guesswork. Retail analytics provide the information for retailers to make informed decisions that can help them compete with bigger businesses—especially as the retail landscape changes in the wake of COVID-19.
