Discount metrics quantify how much margin your variant gives away. They are essential for offer tests where discount behavior is the main lever.

​
Where do discount values come from?

ABConvert calculates total discounts from Shopify order data using discount allocations. For each order, discount value is aggregated from:
  • Product discount value from line-item discount allocations.
  • Order discount value that Shopify allocates across line items.
  • Shipping discount value from shipping-line discount allocations.
These combine into total_discounts, which powers all discount metrics.

​
What do discount metrics mean?

​
With a product group

When you apply a product group, discount metrics count only the order lines of products in the product group. An order counts as discounted when at least one of those lines received a discount. A discount only on shipping, or only on products outside the product group, does not count. Revenue Discount Percentage uses the product group’s revenue before discounts.

​
Why are these metrics critical for offer tests?

In offer tests, conversion or revenue lift is only half the story. You also need to measure discount cost. Use these metrics together to decide whether a variant is truly better:
  • Use Discounted Order Rate to see how broadly the offer is being used.
  • Use Average Discount Value to see the typical cost per order.
  • Use Revenue Discount Percentage and Profit Discount Percentage to quantify margin impact.
