The average cost to get one completed account registration. Meta and TikTok are the platforms that report registrations, so only their spend counts.

​
Formula

Blended Cost per Completed Registration = ( Meta Spend + TikTok Spend ) ÷ Blended Completed Registrations

Formula Components

​
Example

A meal-kit brand asks shoppers to create an account before choosing a plan. In March: Dividing Blended Spend ($28,000) by the same 750 registrations would give $37.33, charging Google’s budget to registrations it didn’t report.

​
How It Works

Upstack adds Meta and TikTok spend and divides by the registrations those two platforms report. Google Ads doesn’t report a registration count, so its spend is left out. In the app the formula reads Meta + TikTok Spend ÷ Completed Registrations. If you run Google Ads, this metric won’t equal Blended Spend ÷ Blended Completed Registrations.
