The ratio of orders from first-time buyers compared to all orders in a given period.

Example

Your store processed 1,247 orders in January with 623 from new customers:

Metric	Value	Interpretation
New Customer Orders	623	First-time buyers
Total Orders	1,247	All orders
NC Order Ratio	0.50	50% acquisition mix

A ratio of 0.50 means half your orders come from new customers—a balanced acquisition/retention split.

How It Works

Shopify identifies new customers by checking if the order is their first completed purchase in your store. The NC Order Ratio divides these first-time buyer orders by your total order count, giving you a decimal between 0 and 1 that represents your acquisition mix.
