Blended Cost per Lead: Cross-Platform Lead Acquisition Cost

Blended Cost per Lead measures how much you spend on average to get one lead. Meta and TikTok are the platforms that report leads, so only their spend counts.

Formula

Blended Cost per Lead = ( Meta Spend + TikTok Spend ) ÷ Blended Leads

Formula Components

Metric	Definition
Meta Spend	Spend from your Meta ad accounts
TikTok Spend	Spend from your TikTok ad accounts
Blended Leads	Leads 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	Leads	Counted in this metric
Meta Ads	$3,000	160	Yes
TikTok Ads	$1,000	40	Yes
Google Ads	$1,000	Not reported	No
Blended Cost per Lead	$4,000	200	$20.00

Dividing Blended Spend ($5,000) by the same 200 leads would give $25.00, charging Google’s budget to leads it didn’t report. Compare $20.00 with your target cost per lead.

How It Works

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