Financial management can be particularly challenging for owners of ecommerce businesses. However, if you keep a close eye on the key performance indicators (KPIs), you may confidently traverse this path. Ecommerce KPIs serve as financial indicators to evaluate the performance and health of businesses. These tools also make it easier to monitor development and enhance KPI reporting. Because of how quickly and often the internet scene is changing, ecommerce enterprises need to be aware of this and be vigilant.

In this blog, we will help you track the pivotal ecommerce KPIs, ensuring your ecommerce business stays in the right direction. Whether you are a major retail player or an inventive entrepreneur, this guide is tailored to all. So, let us begin.

Key Financial & Profitability Ecommerce KPIs

1. Gross Margin Percentage for Product Sold:

The most important key performance indicator KPI in ecommerce is the Gross Margin Percentage for Products Sold, which determines the profitability of each individual product or item sold. After subtracting the cost of goods sold (COGS), it shows the proportion of revenue from product sales that is left over as profit. A smaller percentage denotes decreased profitability, while a larger gross margin indicates a healthy profit margin. Since a healthy cash balance must be maintained by every business, this makes this ecommerce KPI even more essential.

Formula – Gross Profit Margin = (Revenue – Cost of Goods Sold) ÷ Revenue × 100

2. Cost of Goods Sold (COGS):

In KPIs for ecommerce, cost of goods sold is important since it shows how much it actually costs to produce or buy the goods that are sold. Ecommerce businesses can improve their pricing tactics to guarantee high profit margins by vigilant monitoring of COGS.

Formula – COGS = (Beginning Inventory + Purchases during the period) − Ending Inventory

3. Profitability by Product Category:

Examining profitability by product category helps pinpoint your most successful product lines. This valuable insight facilitates the effective allocation of resources and enhances your product offerings to maximise profitability.

Formula – Profitability = Total Revenue (Category) − Total Costs (Category)

4. Profitability by Marketplace Channels:

For ecommerce businesses active on various marketplace channels, evaluation of profitability by channel is necessary. This analysis enables businesses to strengthen resources on the most profitable channels and modify strategies for those that are underperforming.

Formula – Profitability = Total Revenue (Channel) − Total Costs (Channel)

5. Profitability by Business Verticals:

If your ecommerce business operates across different sectors, like online sales, offline retail, and commission-based models, assessing profitability in each segment is vital. This KPI reporting for the ecommerce business offers a detailed view of which areas are most impactful to your total profit.

Formula – Profitability = Total Revenue (Vertical) − Total Costs (Vertical)

6. Loss-Making Items:

Identifying items that are not profitable is crucial for reducing potential financial risks when analysing KPIs for ecommerce. This understanding helps in making strategic decisions like price adjustments or discontinuing unprofitable products to boost the overall profitability of the business.

7. Return on Investment (ROI):

Return on Investment as an ecommerce KPI is valuable in assisting investors to evaluate the effectiveness of their investment. Understanding the ROI aids in optimising resource distribution for better influence, whether on marketing campaigns or for technological enhancements.

Formula – ROI = (Net Profit ÷ Investment Cost) × 100

8. Net Profit Margin:

Net profit margin is an essential key performance indicator that gauges the overall profitability of online sales. This KPI represents the percentage of profit retained by a retailer after considering all expenses associated with managing their online store. A high net profit margin shows a business’s operational efficiency and good profitability. Contrarily, a low net profit margin indicates that a business’s operational inefficiency and that it is not making enough profits.

Formula – Net Profit Margin = (Net Profit ÷ Total revenue) × 100

Important Sales Ecommerce KPIs

1. Gross Merchandise Volume (GMV):

GMV stands for the total value of goods sold on your platform over a specific period, offering a complete synopsis of sales activity. Monitoring GMV as an ecommerce KPI essentially helps in grasping the full scope and performance of any ecommerce business.

Formula – GMV = Sales Price of Goods × Number of Goods Sold

2. Number of Orders:

Tracking the number of orders provides direct insight into customer engagement and purchasing patterns. This ecommerce metric is crucial for evaluating the overall transactional activity on your platform and its rate of growth.

3. Average Order Value (AOV):

The Average Order Value (AOV) measures the typical spending per customer transaction, giving an overview of the spending habits of customers and enabling effectiveness in strategy. A high AOV showcases substantial purchases made by the customers, giving a raise in revenue and profit. In contrast, a low AOV implies smaller purchases, necessitating more sales to reach revenue goals.

Formula – Total Revenue ÷ No. Of Orders

4. Customer Lifetime Value (CLV):

Customer lifetime value (CLV) is a key performance indicator for ecommerce businesses that calculates the total income a company expects to receive from one customer over the duration of their relationship. This metric considers the initial purchase as well as the following transactions, providing opportunities for cross-selling and the likelihood of referrals. When a company understands that a high CLV is attainable, it can confidently invest in obtaining new customers and expanding its revenue streams.

Formula – CLV = Average Revenue Per User × Average Customer Lifespan

5. Customer Acquisition Cost (CAC):

Customer Acquisition Cost (CAC) is a critical ecommerce KPI representing the total expenses you spend to attract and secure new customers for your business. This includes advertising, marketing, and other costs associated with getting people to visit your website and make a purchase. Monitoring CAC helps businesses make informed decisions about their spending on marketing and customer acquisition techniques to optimise profitability.

6. Churn Rate:

This ecommerce KPI measures the percentage of customers who stop purchasing from an online store within a specific period of time, which is often monthly or annually. It signifies the rate at which customers disengage or “churn” from the business’s customer base, indicating potential problems affecting customer retention. An ecommerce business with a high churn rate needs strategies to improve customer loyalty, while one with a low churn rate suggests that the business is effectively retaining its customer base.

Formula – Churn Rate = (Number of Customers Lost in Period ÷ Number of Customers at Start of Period) ×100

7. Sales by Each Marketplace Channel:

This ecommerce KPI tracks revenue generated across different online platforms. It provides insightful data regarding the performance and profitability of the business’s website as well as on each platform, such as Amazon, eBay, and social media channels, where the business is doing its sales. By monitoring sales on each platform, businesses can identify the most profitable channels, further optimise resource allocation, and make strategic adjustments to maximise revenue and market presence.

8. Sales by Product Category:

Another ecommerce KPI is sales by product category which measures the total sales of a particular product category within a specified time frame. This ecommerce metric provides valuable understanding into the performance of different product categories and helps ecommerce businesses identify which categories are making most of the sales and driving revenue into the positive direction. Analysing this KPI helps ecommerce businesses optimise their product offerings, pricing strategies, and marketing efforts to maximise sales and revenue.

9. Sales by Region Demography:

It is an ecommerce KPI that quantifies revenue in specific geographic areas and among different demographic segments. It helps businesses customise their marketing, products, and distribution to reach successful sales regions and target customer groups. Analysing this data enables informed decisions on expanding markets, optimising market presence, and refining product and marketing approaches.

10. Best and Poor Performing Items:

The “best and worst performing item” KPI in ecommerce highlights top-selling and lowest-performing products. It helps businesses find revenue drivers and slow sellers, guiding inventory, pricing, and marketing decisions. High-performing items aid growth by showcasing customer preferences, while insights from low-performing ones indicate improvements, potential discontinuations, or changes in sales strategies.

11. Percentage of Damage/Return to Sales:

The “Percentage of Damage/Return to Sales” KPI measures how much product returns and damage impact sales revenue. A higher percentage indicates a larger portion of sales affected by returns and damage, which is worrisome. In contrast, a lower damage/return to sales percentage is preferable, signifying less revenue loss due to these issues.

Formula – Percentage of Damage/Return = (Total Value of Damaged/Returned Items) ÷ (Total Sales) × 100

Top Ecommerce KPIs for Marketing

1. Website Traffic:

Efficiently monitor and analyse website traffic to gain insights into visitor counts. Higher traffic boosts visibility, which can lead to increased sales opportunities and expanded market reach.

2. Bounce Rate:

Diligently track and assess the percentage of visitors who exit after viewing just one page. A reduced bounce rate indicates enhanced engagement and interest in your content, suggesting a more positive user experience.

Formula – Bounce Rate = (No. Of Single-Page Session ÷ Total No. Of Session) × 100

3. Average Session Duration:

Measure and analyse the duration of visits to your site. Longer visit times imply that your content is engaging and resonates with your audience, enhancing brand visibility and fostering deeper customer connections.

Formula – Average Session Duration = Total Duration of All Sessions ÷ Total No. Of Sessions

4. Conversion Rate:

Assess and examine the percentage of visitors who perform desired actions, like making a purchase. A higher conversion rate not only demonstrates efficient website performance in converting visitors into customers but also signifies a strong sales funnel. Conversely, a low conversion rate can signal several potential issues within a business, such as ineffective marketing strategies, poor website usability, or unappealing product offerings.

Formula – Conversion Rate = Total No. of Conversions ÷ Total No. Of Visitors) × 100

5. Cost Per Acquisition (CPA):

Deeply understand and analyse the cost of acquiring a customer via specific channels. This detailed insight helps in optimising budget distribution towards the most effective channels, ensuring a strategic and cost-efficient approach.

Formula – CPA = Total Marketing and Advertising Costs ÷ Total Number of Acquisitions

6. Impact of Ad Spend on Sales:

It is a critical ecommerce KPI that measures the effectiveness of advertising and marketing expenditures in driving sales revenue. A higher positive impact signifies that advertising efforts drive significant sales growth relative to ad spend. Conversely, a lower or negative impact suggests that advertising expenses may not be generating the desired sales results.

7. Cost Per Click (CPC):

Track and analyse the cost per click on an advertisement. This precise monitoring aids in more effective budget management, offering insights into the efficiency of paid campaigns and identifying opportunities for cost optimisation.

Formula – CPC = Total Cost of the Campaign ÷ Total Number of Clicks

8. Cart Abandonment Rate:

This KPI tracks and analyses the percentage of users who abandon their cart during the purchase process. An ecommerce business must improve the overall user experience and customer satisfaction to lower this rate and optimise the conversion funnel and increase sales.

Formula – Cart Abandonment Rate = (Number of Completed Purchases ÷ Number of Shopping Carts Created) ×100

9. Sale by Business Verticals:

This is another crucial key performance indicator for ecommerce businesses. It tracks verticals, such as retail stores, wholesale distribution, and online platforms. With the help such insightful data businesses get to learn about performing and underperforming channels and can monitor revenue and profitability on a vertical level. Furthermore, this KPI facilitates the identification of expansion prospects, longitudinal sales trends, and alterations in consumer behaviour, such as the shift from physical retail to virtual sales. Business owners can use this information to make data-driven decisions about purchasing marketing campaigns, expanding their product lines, vertical promotions, and overall business strategy.

Top Ecommerce KPIs for Inventory Monitoring

1. Inventory Holding Period:

An important indicator of success in ecommerce is the inventory holding period, which measures the average number of days it takes a business to sell its inventory. A shorter inventory holding period typically denotes efficient inventory management, while a longer inventory holding period may be a sign of issues with slow-moving products, overstocking, or supply chain inefficiencies.

2. Average Age of Inventory:

This KPI is crucial for determining how long merchandise remains in the warehouse on average. Ecommerce businesses can determine whether inventory goods move quickly, slowly, or possibly even become obsolete by examining the average age of their stock. With the use of this data, they can decide whether to fully remove or sell slow-moving or dead inventory at a discount. Regular monitoring of this KPI help enhance cash flow, overall inventory management, and operational efficiency.

3. Average Inventory:

An overview of the average value of your inventory over a specified time period is provided by the average inventory key performance indicator. It calculates the average quantity of stock you hold by dividing the total inventory value by the number of periods.

Formula – Average Inventory = (Beginning Inventory + Ending Inventory) ÷ 2

4. Holding Costs:

Expenses for handling, insurance, and storage space are examples of holding costs related to maintaining inventory. By monitoring this KPI in your ecommerce business reporting, you can better manage and minimise wasteful spending, compute profitability, comprehend the entire cost of products sold, and improve your company’s overall cost efficiency.

Formula – Holding Cost = Storage Costs + Insurance + Taxes + Opportunity Cost of Capital + Shrinkage and Obsolescence Costs

5. Stock Out:

How frequently and how long things are out of stock is shown by the KPI known as stock out. Maintaining a positive brand image and satisfying your customers help minimise the chances of stockouts.

Formula – Stock Out = (Number of items out of stock / Number of items shipped) x 100

6. Time to Ship:

This ecommerce analytics metric gauges the time between order receipt and product shipment. A shorter shipment time boosts customer satisfaction and aids in meeting delivery expectations. On the other hand, if the time between receiving an order and shipping the product is prolonged, it can negatively impact the business in several ways.

Formula – Time to Ship = Time Order Received – Time of Shipment

7. Dock to Stock:

Dock to Stock KPI assesses how effectively your receiving process operates. The time it takes for a product to go from the receiving dock to a retail location is measured. Cutting this time down improves overall operational effectiveness.

Formula – Dock-to-Stock Time = Time of Goods Receipt – Time of Stocking

8. Return Rate:

The percentage of products that customers return is calculated by the return rate key performance indicator. Increased returns may indicate problems with the quality of the product, the accuracy of the fulfilment process, or customer expectations.

Formula – Return Rate = (No. of items Returned ÷ Total Items Sold) ×100

9. Dead Stock:

Products that have not sold for a long time are identified by the dead stock. To prevent investing money in slow-moving products, keeping a watch on this measure helps with decision-making about promotions, discounts, and discontinuation.

Formula – Dead Stock = (Value of Dead Stock ÷ Total Inventory Value) ×100

The data from these KPIs can help you decide which aspects of your ecommerce firm require greater attention and where to allocate additional resources. This will help ensure clear KPI reporting, provide knowledge about how your customers view you, and provide guidance on how to improve the customer experience in general.
