Average Order Value (AoV).

Average Order Value, sometimes called AOV, is the average spend per transaction on your website.

Average order value is a valuable metric for understanding how much your transactions are worth to your business. It is however one half of the coin, with the other being how much you paid to acquire those customers.

This will allow you to know if your transactional value is higher than your Cost Per Acquisition (CPA).

If your Average Order Value is higher than your Cost Per Acquisition, your website is at least making a profit before the cost of goods.

The What, Why and How

What is it?

Average Order Value is the amount of money which is spent per transaction.

However this will only show the spend per transaction NOT the spend per customer. To understand Spend per customer there is a different metric available called Revenue Per User or RPU.

Using both of these will allow you to understand if purchases are being made by a number of loyal customers (Higher RPU than AOV) or new customers (similar AOV to RPU).

Why measure it?

Using Average Order Value (AOV) will give you a good idea on how much your transactions are worth to you.

It will also provide you with a picture of your typical order profile. For example do you usually have a high or low order value.

Looking at conversion rate combined with AOV will provide you a good picture of your Ecommerce performance.

Combining AOV against Cost Per Acquisition will allow you to understand if your orders are profitable (after the cost of media/marketing spend).

How to diagnose it

To carry out the diagnosis you will need:

  • Revenue
  • Number of transactions
  • Items per basket
  • Cost Per Acquisition
  • Across all channels where you can track the purchase

Step 1: Look at the total revenue based on a campaign or a time period. Break the revenue down by channel. Look at the total number of transactions for each channel.

Step 2: Divide revenue by the number of transactions. This will provide you with the Average Order Value. Next apply the same calculation by channel to the get the Average order value by channel.

Step 3: Compare at the Revenue per user (RPU) or Average order value to the Cost per acquisition. If the Average order value is lower than the Cost per acquisition is this is an unprofitable campaign and needs to be resolved.

Step 4:  Finally map out the Average order value against Items per basket. Do this for each of the channels to understand the profile of spend.

Average Order Value
Use this line to compare the spend per transactions. Above the line is above the average and below the line, below the average.
Use this line to understand the number of items included in the transaction. To the left of the middle is above the average and to the right of the middle is below the average number of items per transaction.
Here we have high spend and items. This could be the bundling and higher spending audiences. Aim to target channels here with bundles or higher value items.
Here is the high spend but fewer items. These could be the hero products or the ones which cost a lot. They might be one off purchases, so be mindful of marketing anything other than these products, but it is still a premium or higher value sell.
This is low number of items and spend. Not likely to be your most profitable group, but might be an entry level purchase. Ensure you do not lose too much profit but advertising this too heavily.
This is low spend, but higher number of items. On the face of it, it might seem crazy. However this is quite often the sampling group or free products with purchase. This can be hugely profitable so measure returning purchasers from this group.

How can I calculate Average Order Value (AoV)?

You can calculate the Average Order Value (AOV) on any channel or device as long as you have revenue and number of transactions for channels or devices.

AOV is calculated as the amount of revenue of divided by the number of transactions.

For example: AOV = revenue by channel / transactions by channel.

What are you Top Tips for AoV?

Average Order Value is reliable, in that it tells you how much each transaction is worth to your business. Here are our 3 Top Tips:

TOP TIP 1: However looking at the overall average can hide what is happening. Look at your AoV by channel and device to see if any of these are really bringing down the average.

TOP TIP 2: Look at the items per basket to see how the AoV is being created. Is it one or two expensive items in a transaction or multiple items in a transaction?

TOP TIP 3: Using AoV by channel and device will allow you to compare it against Cost Per Acquisition.

If it is higher than Cost Per Acquisition that channel is making money against the cost of acquiring that visitor. If you drill down even further down to a campaign (within a channel and device) you might some horrors!

TOP TIP 4: Ensure your technical teams are capturing the correct information in AoV for your business.

For example do you want to include delivery costs in your order value? Do you want to include tax in your order value?

Our recommendation is to not include these and treat these as separate pieces of information. The order value, should be the amount of money paid by a customer at the time of they made their purchase with you.

What does a good AoV look like?

The best source of information for this is your website. However it is good to understand how others are performing.

Growcode has carried out some research to collate the data from a variety of sources which includes Monetate (who publish a report from the data collected by their software).

The range however is large, across industries, sources of traffic and devices used for purchasing.

For example Cars and Motorcyling was high at £131, but Health and Wellbeing was only £38.

Looking at devices Monetate published traditional (desktop) at $180, while mobile (smartphone) was $79.

Is AoV different from items per basket?


AoV is how much was spend in a given transaction, typically this is averaged to understand how much your visitors are spending when they buy from you.

Items per basket describes how many items that visitor had when they made a purchase. By looking at the combination of both, you will be able to start to group or segment your visitors.

Some will spend a lot (high average order value) with a large number of items. Suggesting they have purchased bundles.

Some will spend a lot, but with 1 or very few items. This would suggest higher value one off purchases.
