Formula
Cost per Add to Wishlist = Channel Spend ÷ Add to Wishlist Events
Formula Components
Example
Your store spent $2,500 on advertising last week and generated 500 add to wishlist events.
Each wishlist addition cost $5.00 in ad spend.
How It Works
This metric divides your total advertising spend by the number of add to wishlist events tracked by the Upstack pixel. Lower values indicate more efficient spend — you’re generating product interest at a lower cost. Wishlist additions signal high purchase intent, making this a valuable upper-funnel efficiency indicator.When to Use
