Example

Your store averaged 3.0 units per order in March with 2,914 orders:

Week	Orders	Units Sold	Units/Order
Week 1	687	1,923	2.8
Week 2	712	2,279	3.2
Week 3	745	2,384	3.2
Week 4	770	2,156	2.8

How It Works

Units Per Order divides total units sold by total orders. Higher values indicate customers are adding more items per transaction—either through bundles, cross-sells, or natural multi-item purchases.

When to Use

Scenario	Action
Low units per order	Test product bundles or “frequently bought together” recommendations
Declining trend	Review cross-sell placements, shipping thresholds, or product mix
Comparing segments	Analyze new vs. returning customer basket sizes
Evaluating promotions	Measure impact of volume discounts or bundle offers

Metric	Relationship
Units Sold	Numerator: total product quantity
Orders	Denominator: transaction count
NC Units Per Order	Same formula for new customers only
Total AOV	Revenue version—measures value per order
