# Cost per Order Delivered: Ad Spend Efficiency for Fulfilled Orders

> Track your Cost per Order Delivered for Shopify stores. Measure ad spend efficiency for orders that have been fulfilled and delivered to customers.

<Tip>
  Cost per Order Delivered measures how much ad spend it takes to generate a fully delivered order, giving you a true cost efficiency metric that accounts for fulfillment completion.
</Tip>

## Formula

<Info>
  **Cost per Order Delivered** = **Channel Spend** ÷ **Orders Delivered**
</Info>

### Formula Components

| Metric                                                                    | Definition                                                         |
| ------------------------------------------------------------------------- | ------------------------------------------------------------------ |
| [**Channel Spend**](/reference/metrics/advertising/blended/blended-spend) | Total advertising spend across all channels in the selected period |
| **Orders Delivered**                                                      | Count of orders that have been fulfilled and marked as delivered   |

## Example

Your Shopify store spent **\$15,000** on advertising in March. During that period, **375 orders** were fulfilled and delivered to customers.

| Metric                       | Value       |
| ---------------------------- | ----------- |
| Channel Spend                | \$15,000    |
| Orders Delivered             | 375         |
| **Cost per Order Delivered** | **\$40.00** |

***

## How It Works

Cost per Order Delivered calculates your advertising efficiency based on orders that have completed the full customer journey—from click to delivery. Unlike Cost per Purchase, which counts orders at checkout, this metric waits until Shopify marks the order as fulfilled and delivered, giving you a more accurate picture of your true customer acquisition cost.

## When to Use

| Scenario                           | Action                                                                                     |
| ---------------------------------- | ------------------------------------------------------------------------------------------ |
| Measuring true acquisition costs   | Use Cost per Order Delivered to account for canceled orders and returns before fulfillment |
| Comparing fulfillment efficiency   | Compare this metric across channels to see which sources deliver the most reliable orders  |
| Evaluating subscription businesses | Track delivered orders to measure actual recurring shipments, not just initial sign-ups    |
| Analyzing seasonal fulfillment     | Monitor how shipping delays during peak seasons affect your delivered order costs          |
