Example

Your new customers generated $42,400 in net revenue with $18,340 in product costs:

Segment	COGS	Net Revenue	COGS/Net Rate
New Customers	$18,340	$42,400	43.3%
Returning Customers	$24,680	$65,100	37.9%

New customers have higher COGS net rate due to acquisition discounts reducing net revenue.

How It Works

This metric divides New Customer COGS by New Customer Net Revenue. It’s typically higher than the gross rate because discounts and refunds reduce the denominator. Use this for true profitability analysis after accounting for all adjustments.
