How It Works

New Customer Contribution Margin isolates profitability from first-time buyer orders. It takes net revenue from new customers (after discounts and refunds) and subtracts all variable costs—COGS, fulfillment, transaction fees, and marketing. The result shows true profit generated from customer acquisition before fixed costs.
