KPI Definitions - New vs Existing Customers

KPI definitions for the New vs Existing Customer Dashboard

Written by Hannah Shortle

The New vs Existing Customers dashboard focuses on the differing behaviours between new and existing customers. Retail Analytics determines whether a customer is new or existing by looking at your entire order history. Each customer is only defined as 'new' when they place their first order with you; after that point they are defined as 'existing' no matter how long it has been since their previous order.

KPI definitions

  • New Visitors: The number of sessions from visitors who, according to Google's tracking snippet, have never been to your site before and are initiating their first session on your site.

  • Customers Acquired: The number of new customers you acquired, i.e. the number of customers who placed an order with you for the first time.

  • New Customer Gross Revenue: The gross revenue associated with orders placed by new customers.

  • New Customer Revenue %: The proportion of overall gross revenue that came from new customers.


    Formula: new customer gross revenue/total gross revenue

  • New Customer Gross Profit Margin %: The gross profit percentage of the orders placed by new customers including tax.


    Formula: (new customer gross revenue - new customer gross cost of goods sold - new customer shipping cost)/new customer gross revenue

  • New Customer AOV: The average value of orders placed by new customers.


    Formula: new customer gross revenue/number of orders placed by new customers

  • New Customer Discount %: The percentage of revenue lost to checkout discounts for new customer orders. This accounts for discounts applied at checkout only, e.g. a promo code. This does not include discounts as a result of marking items down.


    Formula: new customer checkout discount amount/(new customer gross revenue + new customer checkout discount amount)

    Formula: ad spend/customers acquired
