one-line definition
AOV is a core operating metric that helps small teams make better product and growth decisions.
formula: AOV = Total revenue ÷ Number of orders
tl;dr
AOV is the average revenue per transaction. Raising it by even $5-10 can dramatically change your margins without needing more traffic.
Simple definition
AOV (Average Order Value) is the average amount a customer spends per transaction. It's most relevant for e-commerce, marketplaces, and products with one-time purchases or variable cart sizes. For SaaS with fixed monthly plans, ARPU is usually more useful -- but if you sell add-ons, credits, or one-time features alongside a subscription, AOV still matters.
AOV tells you how effectively you're monetizing each buying moment. Two stores with identical traffic and conversion rates can have wildly different revenue if one has a $35 AOV and the other has a $85 AOV.
How to calculate it
AOV = Total revenue / Number of orders
Say your Gumroad store made $8,400 from 120 orders last month:
AOV = $8,400 / 120 = $70
If you add a bundle option that packages your $29 template with a $19 tutorial, and 30% of buyers take it, your new AOV might jump to $82. Same traffic, same conversion rate, 17% more revenue.
Example
You sell design templates. Your best seller is a $39 Notion template pack. You notice most buyers only buy one item. You create a "Starter Kit" bundle: three templates for $79 (a $38 discount vs. buying separately). Your AOV goes from $42 to $58 over four weeks. You didn't spend a dollar on new traffic -- you just made it easy for people to buy more in a single transaction. Track AOV weekly alongside conversion rate, because a higher AOV means nothing if it tanks your conversion.
