Example

Your e-commerce store spent $12,000 on ads this month across Meta, Google, and TikTok. Your campaigns captured contact form submissions:

Channel	Spend	Contacts	Cost per Contact
Meta Ads	$6,500	380	$17.11
Google Ads	$4,000	245	$16.33
TikTok Ads	$1,500	72	$20.83
Total	$12,000	697	$17.22

Cost per Contact = $12,000 ÷ 697 = $17.22
