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.
