# Other Cost Per Order: Average Additional Cost Per Transaction

> Track average other variable costs per order. Monitor per-transaction fees for insurance, pick & pack, and platform costs.

<Tip>
  Average other variable cost per order—shows the per-transaction burden of miscellaneous fees.
</Tip>

## Formula

<Info>
  **Other Cost Per Order** = [**Other Cost**](/reference/metrics/orders/cogs/other-cost) ÷ [**Total Orders**](/reference/metrics/orders/counts/total-orders)
</Info>

### Formula Components

| Metric                                                            | Definition                                     |
| ----------------------------------------------------------------- | ---------------------------------------------- |
| [**Other Cost**](/reference/metrics/orders/cogs/other-cost)       | Per-order, per-item, and percentage-based fees |
| [**Total Orders**](/reference/metrics/orders/counts/total-orders) | Number of orders placed                        |

| Metadata        |                                            |
| --------------- | ------------------------------------------ |
| **Type**        | Currency                                   |
| **Data Source** | [Upstack Costs](/dashboard/settings/costs) |
| **Aggregation** | Ratio                                      |

## Example

Your store had **\$3,420** in other costs across **1,140** orders:

| Metric                   | Value      |
| ------------------------ | ---------- |
| Other Cost               | \$3,420    |
| Total Orders             | 1,140      |
| **Other Cost Per Order** | **\$3.00** |

Each order incurs \$3.00 in miscellaneous variable fees on average.

***

## How It Works

Divides total Other Cost by order count. This metric helps you understand the fixed-cost-like burden of per-order fees. Use it alongside AOV to ensure pricing covers all variable costs including these miscellaneous fees.

## When to Use

| Scenario          | Action                                   |
| ----------------- | ---------------------------------------- |
| Unit economics    | Factor into per-order profit calculation |
| Pricing floors    | Ensure pricing covers this cost layer    |
| Cost optimization | Identify expensive per-order fees        |
| Vendor comparison | Compare service provider costs           |
