Definition
AOV (average order value) is total revenue divided by number of orders. $48,000 across 600 orders is an AOV of $80. AOV matters for advertising because it sets your CPA ceiling: gross profit per order is AOV multiplied by margin, and that is the most you can pay to acquire a customer.
How it is calculated
AOV = Revenue ÷ Orders
What to know
Raising AOV is often easier than lowering CPA, because AOV depends on your bundle, upsell and free-shipping threshold rather than on winning an auction against every other advertiser.
At a 45% margin, moving AOV from $80 to $100 raises your break-even CPA from $36 to $45. That is a 25% higher bid ceiling without improving a single ad.
