What is average transaction value and how do you calculate it?

Average transaction value (ATV) is the average amount a customer spends each time they buy from your business. To calculate it, divide your total sales revenue by the number of transactions over the same period. If you took £20,000 from 1,000 sales last month, your average transaction value was £20. It's one of the simplest sales metrics you can track, but it's also one of the most useful. Your revenue is driven by two things: how many sales you make and how much each sale is worth. Average transaction value measures the second, so it shows you how much more you could earn from the customers you already have, without needing to find new ones.

What is average transaction value?

Average transaction value is the mean amount spent per sale over a set period, such as a day, a week or a month. A transaction is a single completed sale, whether that's one coffee, a full basket at the till or an online order containing several items. You'll see ATV used most often by businesses that make a high number of smaller sales, such as shops, cafés, restaurants, salons, pubs and ecommerce businesses. In these businesses, a small change in what each customer spends can add up to a big change in revenue across hundreds or thousands of sales. ATV is useful because it separates two different questions. Footfall and website traffic tell you how many people are buying. Average transaction value tells you how much each of those people is spending. If your revenue rises or falls, looking at both figures together shows you which one moved, and that tells you where to focus.

How do you calculate average transaction value?

The formula for average transaction value is:

Average transaction value = total sales revenue ÷ number of transactions

Both figures must cover the same period. Most point of sale (POS) systems, card terminal providers and ecommerce platforms report them for you, but you can also work it out from your accounting software or till reports.

1. Choose the period you want to measure, such as last week, last month or last quarter.

2. Find your total sales revenue for that period from your till reports, card terminal statements or accounting software.

3. Find the total number of transactions over the same period.

4. Divide your total sales revenue by the number of transactions. The answer is your average transaction value.

Before you start, decide whether you'll use revenue including or excluding value added tax (VAT), and whether you'll take off refunds and returns. Excluding VAT and deducting refunds gives a truer picture of the money your business keeps. Whichever you choose, use the same method every time, so you can compare one period with the next.

What does a worked example of average transaction value look like?

Here's an example for an independent café, using its figures across three months.

Between January and February, revenue grew by £1,400 because the café served 200 more customers. Each customer spent the same £7.00, so all of that growth came from footfall. Between February and March, the number of transactions stayed at 2,400, but revenue rose by another £2,400. That growth came entirely from customers spending an extra £1.00 each, perhaps because the café started offering a pastry with every coffee at a small discount. This is why ATV is worth tracking alongside your total sales. Without it, both months simply look like growth. With it, the café can see that a small change at the till earned more than winning 200 extra customers did.

What is a good average transaction value?

A good average transaction value is one that's rising over time and comfortably covers the cost of making each sale. There isn't one target figure that suits every business, because what customers spend depends on what you sell. A café and a furniture shop will always have very different ATVs, and neither is better than the other. For context, UK Finance's Card Spending Update for November 2025 reported the total value and number of UK card payments that month. Dividing one by the other gives these averages:

These national figures cover every type of purchase, from a bus fare to a holiday, so they're not a benchmark for your business. The more useful comparisons are:

• Your own ATV over time shows whether customers are spending more or less with you each time they buy.

• Your ATV by day, season or channel shows when and where customers spend the most, such as weekends against weekdays or online against in store.

• Your ATV against your cost per sale shows whether each transaction earns enough to cover what it costs you to make it, including staff time, packaging, delivery and card fees.

A falling ATV isn't always bad news. It can mean you've attracted lots of new customers trying you out with smaller purchases, which may grow into bigger spending later.

How is average transaction value different from average order value?

Average transaction value and average order value (AOV) are calculated in the same way: total revenue divided by the number of sales. The difference is mostly in where the terms are used. ATV is more common in shops, hospitality and other businesses that take payments in person, while AOV is more common in ecommerce, where each sale is an order. ATV is also often confused with other sales metrics that measure something slightly different.

These metrics work best together. If your ATV goes up, units per transaction and average selling price tell you why. A higher UPT means customers are buying more items, while a higher ASP means they're choosing more expensive ones or you've raised your prices.

Why does average transaction value matter for your business?

Average transaction value matters because it's one of only two levers that drive your sales. Your total revenue is your number of transactions multiplied by your ATV, so growing either one grows your business. Raising your ATV is often the cheaper option. Finding new customers usually means spending on marketing, promotions or extra staff. Persuading existing customers to spend a little more each visit can cost very little, because they're already in your shop or on your website and ready to buy.

ATV also affects your profit margin on each sale. Many of the costs of making a sale stay roughly the same whatever the customer spends, such as the time it takes to serve them, pack an order or process a payment. Some card processing fees include a fixed charge per transaction, which takes a bigger share of a small sale than a large one. A higher ATV spreads these fixed costs across more revenue, so more of each sale becomes profit.

Finally, ATV helps you plan. Once you know what a typical customer spends, you can estimate how many sales you need to hit a revenue target, how much stock to order for a busy period and how many staff you'll need on shift. Using your ATV and expected number of transactions in a cash flow forecast also gives you a more realistic view of the cash coming in over the weeks ahead, especially around seasonal peaks and quieter spells.

What can make your average transaction value misleading?

Average transaction value is a simple sum, but a few things can make the figure look better or worse than it really is.

• A single very large sale, such as a bulk or corporate order, can push your ATV up for that period even though your typical customer spent the same as usual.

• Refunds and returns that aren't deducted from revenue can make your ATV look higher than the money you actually kept.

• Mixing revenue that includes VAT in one period with revenue that excludes it in another makes your figures impossible to compare fairly.

• Discounts and promotions can lower your ATV in the short term, even when they bring in extra customers who return and spend more later.

• Seasonal swings, such as the run up to Christmas or a quiet January, can make a month look unusually strong or weak.

To get a clearer picture, compare like for like periods, such as this December against last December, and look at the median transaction as well as the average. The median is the middle value when all your sales are lined up from smallest to largest, so one unusually large order can't distort it.

How can you increase your average transaction value?

You can increase your average transaction value by encouraging customers to buy more items each time, choose higher value items, or both. The best approach depends on what you sell and how customers buy from you.

• Upselling encourages customers to choose a better or larger version of what they came for, such as a large coffee instead of a regular or a premium service package instead of a basic one.

• Cross selling suggests items that go well with what the customer is already buying, such as a case with a new phone or a dessert with a main course.

• Bundling related products into a set at a slightly lower combined price gives customers a reason to buy more than one item.

• Setting a minimum spend for free delivery encourages online shoppers to add one more item to reach the threshold.

• Placing smaller, lower priced items near the till or at checkout makes it easy for customers to add something on impulse.

• Training your team to recommend products naturally helps them spot opportunities to add value without feeling pushy.

• Reviewing your pricing makes sure your prices reflect the value you offer and keep up with your rising costs.

• Rewarding customers through a loyalty scheme with spend based rewards, such as points for every pound spent, gives them a reason to spend more each visit.

Track your ATV for a few weeks before and after each change, so you can see which ideas actually work for your customers. Keep an eye on your number of transactions too, because a tactic that raises ATV but puts customers off coming back may not grow your revenue overall.

If you need funding to put some of these ideas into practice, such as new stock lines, a shop refit or an upgraded till system, a merchant cash advance can help. It's repaid as a share of your daily card sales, so repayments rise on busy days and fall in quieter spells. At Capitalise, we can help you compare options from our panel of 130+ lenders.
