Example

Your returning customers generated $65,100 in net revenue with $24,680 in product costs:

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

Returning customers have lower COGS net rate—better margins even after adjustments.

How It Works

This metric divides Returning Customer COGS by Returning Customer Net Revenue. It’s typically higher than the gross rate because discounts and refunds reduce the denominator. Use this for true profitability analysis of your repeat buyer segment.
