Average Transaction Value Formula: How to Calculate AOV

Average transaction value, also called average order value or AOV, tells you how much a typical customer spends per visit. Here's the formula, a worked example, and the two different levers that actually move it.

The formula

Worked example

$8,400 ÷ 210 = $40.00. That number alone doesn't say much in isolation, it becomes useful once you track it week over week and compare it against items per transaction, since the two together tell you whether growth is coming from bigger baskets or higher prices.

Two ways to grow it, and they're not the same

• More items per transaction — add-ons, bundling, upsell prompts at checkout. This is the healthier lever because it usually comes with a happier customer walking out with more of what they needed.
• Higher price per item — trading up customers to a pricier option. This works but has a ceiling, and pushed too hard it can quietly hurt conversion and repeat visits.

Watching AOV next to items per transaction tells you which lever is actually doing the work, instead of guessing.

Why weekly beats monthly for this one

A monthly AOV smooths out everything that's actionable — a bad week gets buried in a good month, and by the time you notice, three or four weeks of coaching opportunity are already gone. Checking it weekly, alongside sales per labor hour, is what turns AOV from a report-card number into something you can actually coach a team around in real time.
