Average Purchase Revenue

Average purchase revenue is total purchase revenue divided by the number of transactions over a period — the average value of a single order. It is GA4's name for what most people call average order value, or AOV: how much a typical customer spends when they buy.

Why it matters

It's one of the few levers a small store can pull without finding more customers. Lifting average purchase revenue — through bundles, an upsell, free shipping over a threshold — grows revenue from the same traffic. It also frames every other number: a 2% conversion rate means something very different at a $30 average order than at a $300 one.

A concrete example

Say a small craft store runs a "free shipping over $50" banner. Average purchase revenue rises from $38 to $54 over the next month, while transaction count holds steady. Same number of buyers, more per order — revenue is up roughly 40% with no extra traffic. The metric makes the win visible and ties it directly to the change you made.

The common misreading

The mistake is reading a rising average as pure good news. A jump can also mean your cheaper products stopped selling, leaving only big-ticket orders behind — fewer customers, higher average, shrinking business. Always read average purchase revenue next to transaction count and total revenue, never on its own. One number rising while another falls is the story that matters.
