Discount rate
How much of your list price you gave away.
Formula
(Price reductions + discount codes) ÷ GMV
Discount rate is price reductions plus discount codes as a share of GMV. Splitting the two matters: a price reduction is a decision you made about the catalogue, a discount code is one a customer applied.
Read it per product. A single line running at 25 percent discount inside a catalogue averaging 3 percent is a pricing decision, not a promotion.
It is one of the two things that separates GMV from gross revenue, the other being shipping revenue.
