Example

Your store had $18,421 in variable costs across 1,842 orders:

Metric	Value
Variable Costs	$18,421
Total Orders	1,842
Variable Costs Per Order	$10.00

Each order incurs $10.00 in variable operational costs on average.

How It Works

Divides total Variable Costs by order count. This metric helps you understand the fixed-cost-like burden of per-order operational fees. Add this to COGS Per Order to see the total cost per transaction before margin.

When to Use

Scenario	Action
Unit economics	Calculate per-order profit after all costs
Pricing floors	Ensure AOV covers COGS + Variable Costs per order
