Blended Cost per Appointment: Cross-Platform Booking Acquisition Cost

Blended Cost per Appointment measures how much you spend on average to drive each appointment or booking through your ads. Meta and TikTok are the platforms that report appointments, so only their spend counts.

Formula

Blended Cost per Appointment = ( Meta Spend + TikTok Spend ) ÷ Blended Appointments Scheduled

Formula Components

Metric	Definition
Meta Spend	Spend from your Meta ad accounts
TikTok Spend	Spend from your TikTok ad accounts
Blended Appointments Scheduled	Appointment bookings that Meta and TikTok attribute to your ads

Metadata
Type	Currency
Data Source	Meta Ads, TikTok Ads
Aggregation	Ratio

Example

Your business ran ads on all three platforms last month:

Platform	Spend	Appointments	Counted in this metric
Meta Ads	$7,000	200	Yes
TikTok Ads	$2,000	50	Yes
Google Ads	$3,000	Not reported	No
Blended Cost per Appointment	$9,000	250	$36.00

Dividing Blended Spend ($12,000) by the same 250 appointments would give $48.00, charging Google’s budget to bookings it didn’t report. Compare $36.00 with the revenue a booked customer brings.

How It Works

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