Cost per Sign Up measures the average ad spend required to generate one sign up (registration) event on your site.

Formula

Cost per Sign Up = Channel Spend ÷ Sign Ups

Formula Components


Example

Your store spent $8,000 on ads in February and tracked 1,600 sign up events.

How It Works

The Upstack pixel captures sign up events when visitors register for an account on your site. Cost per Sign Up divides your total ad spend by the number of registration events, showing how efficiently your ads drive new account creation. Lower values indicate more cost-effective acquisition of registered users who can be nurtured through email and remarketing.
