Example

Your store spent $12,000 on ads this month driving users to your registration flow. The Upstack pixel tracked registration completions across channels:

Channel	Spend	Registrations	Cost per Registration
Meta Ads	$6,500	325	$20.00
Google Ads	$4,000	180	$22.22
TikTok Ads	$1,500	95	$15.79
Total	$12,000	600	$20.00

Cost per Complete Registration = $12,000 ÷ 600 = $20.00

This metric divides your total advertising spend by complete registration events tracked by the Upstack pixel. A CompleteRegistration event fires when a visitor finishes creating an account or completing a signup flow. Use this metric to evaluate how efficiently your campaigns acquire registered users who can later be nurtured into paying customers.
