Example

Your TikTok prospecting campaign spent $2,400 last week and drove 800 add to carts.

Campaign	Spend	Add to Carts	Cost/ATC
Prospecting - Video	$1,500	600	$2.50
Retargeting - Carousel	$900	200	$4.50
Total	$2,400	800	$3.00

How It Works

TikTok tracks add-to-cart events through its Pixel or Events API. Upstack calculates cost per add to cart by dividing your total TikTok ad spend by the number of attributed add-to-cart events during the selected period.
