AOV (Average Order Value), or average order value, is the average amount customers spend per order over a given period. This metric is calculated by dividing total revenue by total orders, helping businesses measure sales efficiency and optimize profit per transaction.
Key points
- Formula: AOV = Total revenue ÷ Total orders; exclude returns and canceled orders, and calculate over the same time period.
- AOV is based on revenue, not profit, and is measured per order rather than per customer; it is often tracked alongside conversion rate and purchase frequency.
- Increasing AOV is often the cheapest way to grow revenue because it does not require additional customer acquisition costs, while also helping offset customer acquisition cost (CAC).
- Common tactics include upsell, cross-sell, free shipping thresholds, bundles/product sets, and gifts tied to order value milestones.
- Common mistakes: focusing only on AOV while ignoring profit margins, discounting too heavily to hit bundle thresholds, forcing upsells that drive cart abandonment, and comparing AOV with competitors in other industries.
What is AOV? AOV (Average Order Value), or average order value, is the average amount customers spend per order over a given period. This metric is calculated by dividing total revenue by total orders, helping businesses measure sales efficiency and optimize profit per transaction.
A detailed definition of AOV
AOV stands for Average Order Value. It is one of the core metrics in e-commerce, reflecting how much customers typically spend each time they shop at your store.
Unlike total revenue, which only tells you how much you sold, AOV shows the quality of each transaction. A store may have a large number of orders but a low AOV, meaning each order brings in less value and order processing costs (packing, shipping, customer service) can eat into profit. Conversely, increasing AOV is often the cheapest way to grow revenue because you do not have to spend more to acquire new customers.
AOV is often tracked alongside two other metrics: conversion rate and purchase frequency. Together, these three determine the revenue of an online retail business.
Why AOV matters for businesses
AOV matters because it directly affects profit and marketing efficiency. Here are the main reasons:
- Increase revenue without adding new customers: Acquiring a new customer is much more expensive than getting existing customers to spend more. Raising AOV helps you make the most of existing traffic.
- Offset customer acquisition cost (CAC): If the ad cost to get one order is 80,000đ, a higher AOV helps that order remain profitable.
- Evaluate promotion effectiveness: AOV shows whether bundle offers, free-shipping thresholds, or upsells are actually making customers spend more.
- Guide pricing and product strategy: Tracking AOV over time helps identify which products lift order value and which ones lead customers to buy only individual items.
For businesses running Facebook or Google ads, AOV is a key variable in budget planning. When AOV increases, you can accept a higher cost per order while still maintaining profit margins, allowing you to compete more effectively in ad auctions than competitors.
How to calculate AOV and apply it
The AOV formula is very simple:
AOV = Total revenue ÷ Total orders
For example, if a store generates 200 million đồng in revenue from 1,000 orders in a month, AOV will be 200,000,000 ÷ 1,000 = 200,000đ per order.
Note when calculating AOV: this metric is based on revenue, not profit, and is calculated per order rather than per customer (one customer may place multiple orders). For an accurate view, you should exclude returns and canceled orders and calculate over the same time period.
After knowing the current AOV, businesses can apply common tactics to increase this metric:
- Upsell: Suggest a higher-end version of the product the customer is viewing (for example, a larger size or a premium package).
- Cross-sell: Recommend complementary products such as “Frequently bought together” or “Customers also bought”.
- Free shipping threshold: Offer free shipping for orders above a certain amount to encourage additional purchases.
- Bundles and product sets: Package multiple items together at a slightly discounted price compared with buying them separately.
- Gifts tied to value milestones: Give a gift when the order reaches a threshold to encourage customers to add more items to their cart.
Real-world examples in the Vietnamese market
To make it easier to understand, let’s look at how some business models in Vietnam apply AOV in practice.
A cosmetics store on Shopee had an initial AOV of 180,000đ. They set a free-shipping threshold for orders from 250,000đ and created “lipstick + makeup remover” bundles at a promotional price. After two months, AOV rose to 235,000đ, and revenue increased even though order volume stayed nearly the same.
A fashion brand selling through its own website applied cross-sell on the checkout page: when customers bought a shirt, the system suggested matching accessories such as belts or socks. About 12% of customers added an item, pushing AOV from 420,000đ to more than 480,000đ.
In the fast-delivery food and beverage sector, chains often use combos like “1 drink + 1 topping + 1 cake” along with a reduced delivery-fee threshold. This is a typical way to increase AOV in a context where shipping fees make up a large share of each small order.
Common mistakes when optimizing AOV
Chasing a higher AOV is good, but many businesses make mistakes that make the metric look better on reports while profit does not increase:
- Looking only at AOV and ignoring profit: Increasing AOV by selling more low-margin products may not deliver proportional profit. Always track AOV together with gross margin.
- Discounting too heavily to hit bundle thresholds: Strong promotions may get customers to buy more, but total profit decreases. Discounts need to be calculated carefully.
- Forcing upsells that feel annoying: Too many pop-ups suggesting additional purchases can increase cart abandonment and reduce both conversion rate and revenue.
- Comparing AOV with competitors in other industries: AOV depends heavily on product type. Comparing the AOV of an accessories store with that of an electronics store is meaningless.
- Ignoring per-order operating costs: Raising AOV while increasing the number of items per order can also raise packing and return costs if not controlled.
A healthy approach is to view AOV as part of the bigger picture, including revenue, gross profit, customer acquisition cost, and customer lifetime value (CLV), rather than optimizing a single number in isolation.
Frequently asked questions about AOV
What is a good AOV?
There is no universally “good” AOV number for every industry because it depends on the product type and business model. Instead of comparing yourself with other industries, compare your own AOV over time: if the metric rises steadily while maintaining profit margins, that is a good sign.
How is AOV different from average revenue per customer?
AOV is calculated per order, while average revenue per customer is calculated per customer and may include multiple orders. A customer placing three orders counts as three orders in AOV but only one customer in the per-customer revenue metric.
What is the fastest way to increase AOV?
Two quick and effective ways are to set a free-shipping threshold slightly above the current AOV and enable product recommendations on the cart or checkout page. Both are easy to implement on platforms like Shopee, Lazada, or custom-built websites and can show results within a few weeks.
Should you trade conversion rate for higher AOV?
Balance is necessary. If tactics to raise AOV confuse customers or make them feel pressured to buy, causing conversion rate to drop sharply, total revenue may decline. Run A/B tests and track both metrics before rolling out changes broadly.

Frequently asked questions
What is AOV and why is it important for online stores?
AOV (Average Order Value) is the average order value, calculated by dividing total revenue by the number of orders over a given period. This metric matters because increasing AOV helps you earn more from the same number of customers, improving profit without increasing the cost of acquiring new traffic.
How do you calculate and increase AOV for a store?
AOV equals revenue divided by the number of orders; to increase it, you can suggest add-on purchases, sell bundles, set a free-shipping threshold, or offer discounts when customers buy more. Well-designed upsell and cross-sell tactics encourage customers to spend more per order while still feeling like they are getting value.
How is AOV different from revenue per customer?
AOV measures the average value of each order, while revenue per customer measures the total amount one customer spends across multiple purchases. A customer may have a low AOV but buy frequently, resulting in high lifetime value; therefore, you should look at both to understand how customers create value.
