Example

Your nonprofit spent $5,000 on ads last month and generated 250 donations:

Channel	Spend	Donates	Cost per Donate
Meta	$3,000	150	$20.00
Google	$1,500	75	$20.00
TikTok	$500	25	$20.00
Total	$5,000	250	$20.00

How It Works

Cost per Donate divides your total advertising spend by the number of donate events captured by the Upstack pixel. These events fire when visitors complete a charitable donation action on your site. Lower values indicate more efficient donor acquisition—you’re paying less for each new donation.
