Example

Your new customers generated $47,200 in gross revenue with $18,340 in product costs:

Segment	COGS	Gross Revenue	COGS/Gross Rate
New Customers	$18,340	$47,200	38.9%
Returning Customers	$24,680	$68,400	36.1%

New customers have a higher COGS rate—they often purchase starter bundles or lower-margin acquisition products.

How It Works

This metric divides New Customer COGS by New Customer Gross Revenue. Higher percentages indicate new customers are buying higher-cost products relative to revenue. Compare to returning customer rate to understand how cost efficiency differs by segment.
