# CM4 per Order: Operating Profit per Order

> Track CM4 per order for your Shopify store. Measure average operating profit per order.

<Tip>
  CM4 per Order measures the average operating profit per order—your true profit contribution from each transaction after all costs.
</Tip>

## Formula

<Info>
  **CM4 per Order** = **CM4** ÷ **Orders**
</Info>

### Formula Components

| Metric                                                                          | Definition             |
| ------------------------------------------------------------------------------- | ---------------------- |
| [**CM4 (Operating Profit)**](/reference/metrics/orders/contribution-margin/cm4) | Total operating profit |
| [**Orders**](/reference/metrics/orders/counts/orders)                           | Total order count      |

| Metadata        |                                                                      |
| --------------- | -------------------------------------------------------------------- |
| **Type**        | Currency                                                             |
| **Data Source** | [Shopify](/sources/shopify), [Upstack Costs](/sources/upstack-costs) |
| **Aggregation** | Average                                                              |

## Example

Your Shopify store has **\$20,000** CM4 from **1,250** orders.

| Component         | Value    | Calculation            |
| ----------------- | -------- | ---------------------- |
| CM4               | \$20,000 | Total operating profit |
| Orders            | 1,250    | Order count            |
| **CM4 per Order** | **\$16** | \$20,000 ÷ 1,250       |

***

## How It Works

CM4 per Order shows your true profit per transaction after all costs—COGS, fulfillment, marketing, agency fees, and OPEX. This is the ultimate unit economics metric. A \$16 CM4 per Order means each order generates \$16 in operating profit.
