How It Works

This metric divides new customer contribution margin by new customer net revenue to show what portion of acquisition revenue converts to profit. Lower percentages indicate higher relative costs (COGS, fulfillment, marketing) against first-order revenue—common for brands investing heavily in customer acquisition.
