<Tip>

</Tip>

## Formula

<Info>
  **New Customer Tax Per Order** = [**New Customer Tax**](/reference/metrics/orders/adjustments/new-customer-tax) ÷ [**New Customers**](/reference/metrics/orders/customers/new-customers)
</Info>

### Formula Components

| Metric                                                                         | Definition                                       |
| ------------------------------------------------------------------------------ | ------------------------------------------------ |
| [**New Customer Tax**](/reference/metrics/orders/adjustments/new-customer-tax) | Total tax collected from first-time buyer orders |
| [**New Customers**](/reference/metrics/orders/customers/new-customers)         | Number of orders from first-time buyers          |

| Metadata        |                             |
| --------------- | --------------------------- |
| **Type**        | Currency                    |
| **Data Source** | [Shopify](/sources/shopify) |
| **Aggregation** | Ratio                       |

## Example

Your store collected **\$1,890** in tax from **270 new customer orders** in April:

| Metric               | Value      |
| -------------------- | ---------- |
| New Customer Tax     | \$1,890    |
| New Customer Orders  | 270        |
| **NC Tax Per Order** | **\$7.00** |

***

## How It Works

This metric divides total tax collected from new customers by their order count. Higher values often correlate with larger first-time orders or sales in higher-tax jurisdictions. Use it alongside geographic segmentation to understand regional tax burdens affecting new customer acquisition economics.

## When to Use

| Scenario          | Action                                                                  |
| ----------------- | ----------------------------------------------------------------------- |
| Regional analysis | Compare across states/countries to understand tax impact on acquisition |
| New vs. returning | Benchmark against returning customer tax to spot purchasing differences |
| Total order cost  | Combine with AOV to show customers' complete cost burden                |
| Campaign planning | Factor regional tax into ROAS targets for new customer campaigns        |
