What it means
AOV is calculated by dividing total revenue by the number of orders in a period. If a shop took $180,000 from 3,000 orders last month, its AOV was $60.
The figure is simple, but it ties directly to profit, because every order has a cost of its own. The reason AOV matters is that many costs are per order, not per dollar.
Picking, packing, payment processing and delivery charges are largely fixed for each parcel, so a $90 basket is far more profitable than a $30 one. Raising AOV spreads those fixed order costs over a larger sale.
Companies lift AOV with tactics such as free-shipping thresholds, bundles, volume discounts, product recommendations and loyalty offers. For example, offering free delivery above $75 encourages customers with a $60 basket to add another item.
Each tactic should be tested, since a discount that raises AOV but cuts margin may reduce total profit. AOV should be viewed together with order volume and conversion rate.
Revenue is the product of the number of orders and AOV, so a rise in AOV can be cancelled by a fall in orders, for instance if a free-shipping threshold deters smaller buyers. Segmenting AOV by channel, new versus returning customers and product category usually reveals more than the overall average, because each group shops in a different way.
Like any mean, AOV can be skewed by a few very large orders, especially in business-to-business sales. Analysts often check the median order value alongside it, and exclude returns or cancelled orders so the figure reflects real sales.
Profitability is the real test of AOV. A useful companion measure is contribution per order, which is the revenue from an order minus the direct costs of fulfilling it, including the product, packaging, payment fees and delivery.
Raising AOV is only worthwhile if contribution per order rises with it.
In practice
Real-world examples
Example 1
A coffee roaster sells beans online and offers a bundle of three bags at a 10% discount. Many customers who would have bought one $18 bag now buy the $48.60 bundle, which raises the AOV from $22 to $31.
Example 2
A clothing retailer with an online shop displays "complete the outfit" suggestions at checkout. Customers add an average of one extra item at $25, which lifts AOV by around 15%.
Example 3
A business-to-business supplier of cleaning products sets a minimum order of $250 to cover delivery costs. The finance manager notes that the AOV is $410, which comfortably covers the cost of each drop. The company reviews each month whether the larger orders still cover the costs of picking and packing.
Think of it
AOV is how much customers spend on average per purchase-your typical transaction size.
Formula
Calculation
Average order value = Total revenue / Number of orders
Suppose an online store earned $180,000 of revenue from 3,000 orders in a month. AOV = 180,000 / 3,000 = $60.
The store introduces free shipping on orders over $75, and the next month's results are $198,000 from 2,900 orders. New AOV = 198,000 / 2,900 = $68.28. Revenue rose by 198,000 - 180,000 = $18,000, which is 10%, even though the number of orders fell by 100.Case study
Seen in the real world
Harbour Street Books is an illustrative, fictional online bookshop with 5,000 orders a month at an AOV of $28, giving revenue of $140,000. Delivery cost the shop $6 per parcel, a figure that did not change with the size of the order.
The marketing manager proposed free delivery on orders over $35. Over the following month, orders fell to 4,700, but AOV rose to $36.50, so revenue was $171,550 and the shop absorbed delivery costs on only part of its orders.
The finance director calculated that profit per order had improved because the fixed $6 delivery cost was spread across larger baskets. The illustrative lesson is that AOV can improve profit even when order numbers dip slightly, provided margins are watched. She also tracked contribution per order, which rose from $7.20 to $9.80, confirming that the larger baskets were genuinely more profitable and not just bigger.
Watch out
Common mistakes
- Focusing on AOV alone, when a higher AOV with far fewer orders may reduce total revenue.
- Including cancelled or returned orders in the calculation, which overstates the real value of each sale.
- Using discounts to raise AOV without checking margin, which can lift sales and still reduce profit.
Questions
People also ask
How is AOV different from customer lifetime value?
AOV looks at a single order, whereas lifetime value looks at everything a customer spends over the whole relationship.
What is a good AOV?
It depends on the industry and the product, so the useful comparison is with your own history and with similar businesses, tracked month by month.
Should AOV be measured before or after discounts?
Most businesses use revenue after discounts and before shipping and taxes, but consistency matters more than the exact choice.
