## Formula

<Info>
  **New Customer Shipping %** = ( [**New Customer Shipping**](/reference/metrics/orders/adjustments/new-customer-shipping) ÷ [**New Customer Total Revenue**](/reference/metrics/orders/revenue/new-customer-total-revenue) ) × 100

## Example

Your store launched a **free shipping over \$75** promotion targeting new customers in March.

| Period   | NC Shipping | NC Total Revenue | NC Shipping % |
| -------- | ----------- | ---------------- | ------------- |
| January  | \$6,350     | \$84,670         | 7.5%          |
| February | \$5,890     | \$89,230         | 6.6%          |
| March    | \$2,450     | \$98,000         | 2.5%          |

## How It Works

New Customer Shipping % divides shipping revenue from new customers by their total revenue and multiplies by 100. A declining percentage often signals successful free shipping promotions or higher average order values qualifying for free shipping thresholds among first-time buyers.
