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

## Formula

<Info>
  **New Customer Order Ratio** = **New Customer Orders** ÷ **Total Orders**
</Info>

### Formula Components

| Metric                                                                          | Definition                                                      |
| ------------------------------------------------------------------------------- | --------------------------------------------------------------- |
| [**New Customer Orders**](/reference/metrics/orders/counts/new-customer-orders) | Count of orders placed by customers making their first purchase |
| [**Total Orders**](/reference/metrics/orders/counts/orders)                     | Count of all completed orders in the selected period            |

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

## 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.

## When to Use

| Scenario                         | Action                                                    |
| -------------------------------- | --------------------------------------------------------- |
| Balancing growth vs. retention   | Target 0.3–0.5 ratio for healthy DTC businesses           |
| Evaluating acquisition campaigns | Rising ratio during campaigns confirms new customer reach |
| Diagnosing declining revenue     | Low ratio with flat sales suggests retention issues       |
| Seasonal planning                | Compare ratios across holiday periods to set expectations |
