The AOV formula
Average order value = Total revenue ÷ Number of orders
AOV is how much a customer spends per order — and lifting it is one of the cheapest ways to grow, because you already have the customer.
Average order value = Total revenue ÷ Number of orders
Winning a new customer costs money — ads, discounts, time. Getting an existing customer to spend a bit more in the same order costs almost nothing. And because the fixed costs of an order (payment fee, packing time, the trip to the post office) stay roughly the same, spreading them over a bigger basket lifts your margin, not just your revenue.
That’s why AOV sits alongside margin as a core profit metric: margin is how much you keep per dollar, AOV is how many dollars per order, and together they drive profit per customer.
Every AOV tactic has a margin cost — a discount, a free-shipping giveaway, a bundle price. Before you launch one, check it still leaves a healthy margin with the profit margin calculator, and see how discounts affect profit margin so a bigger basket doesn’t quietly cost you money.

Average order value (AOV) = total revenue ÷ number of orders. If you made $12,000 across 400 orders, your AOV is $30. It measures how much a customer spends per transaction on average.
Raising AOV grows revenue without the cost of acquiring new customers, so it usually improves profit margin too — the fixed costs of processing and shipping an order are spread over a larger sale. It's often the cheapest growth lever a store has.
There's no universal 'good' AOV — it depends entirely on what you sell. What matters is the trend: a rising AOV over time, and an AOV comfortably above your cost to fulfil and acquire each order. Track it monthly against your own baseline.
Common tactics include free-shipping thresholds, product bundles, volume discounts, cross-sells and upsells at checkout, and loyalty rewards for larger baskets. Each nudges customers to add a little more per order.
Usually, but not if you buy the higher AOV with deep discounts that erode your margin. A free-shipping threshold works because the extra item's margin more than covers the shipping. Always check the margin impact of any AOV tactic before rolling it out.
