Average Order Value (AOV) is one of the three fundamental ecommerce metrics, alongside conversion rate and traffic. It measures the average amount a customer spends per transaction on your store. Understanding and improving your AOV is one of the most direct paths to increasing revenue without needing more traffic or higher conversion rates.
This guide explains what AOV is, how to calculate it, what UK benchmarks look like, and practical strategies to increase it on your Shopify store.
Definition
Average Order Value (AOV) is the average monetary value of each order placed on your ecommerce store over a given time period. It is calculated by dividing your total revenue by the number of orders.
AOV = Total Revenue / Number of Orders
For example, if your store generated £50,000 from 1,000 orders in a month, your AOV is £50.
Why AOV matters
AOV matters because it directly determines how much revenue you generate from each customer interaction. A higher AOV means more revenue per transaction, which improves profitability and reduces the pressure on customer acquisition.
- Profitability — Higher AOV spreads fixed costs (shipping, packaging, payment processing) across more revenue, improving margins
- CAC efficiency — If your customer acquisition cost is £20, an AOV of £80 is far more profitable than an AOV of £30
- Growth leverage — Increasing AOV by 20 per cent has the same revenue impact as increasing traffic by 20 per cent, but is typically much cheaper to achieve
How AOV works
AOV is influenced by several factors: your product pricing and range, the effectiveness of your upselling and cross-selling, your shipping thresholds, bundle offers, and the overall shopping experience on your store.
AOV is not a static number. It varies by time period (seasonal fluctuations), customer segment (new vs returning), marketing channel (organic vs paid vs email), and product category. Understanding these variations helps you make targeted improvements.
AOV vs revenue per customer
AOV measures per-transaction value. Revenue per customer (or customer lifetime value) measures total value across all transactions. A customer with a £50 AOV who orders three times has a customer revenue of £150. Both metrics are important, but they measure different things.
How to calculate AOV
The basic formula is straightforward:
| Metric | Value |
|---|---|
| Total revenue (month) | £75,000 |
| Number of orders | 1,250 |
| AOV | £60 |
In Shopify, AOV is available in your Analytics dashboard under Overview. In Google Analytics, you can find it under Ecommerce reports. Klaviyo tracks AOV as part of its revenue reporting.
Real-world examples
Consider two UK ecommerce brands with the same monthly traffic (50,000 visitors) and conversion rate (2 per cent), producing 1,000 orders per month:
| Brand | AOV | Monthly revenue |
|---|---|---|
| Brand A | £45 | £45,000 |
| Brand B | £72 | £72,000 |
Brand B generates 60 per cent more revenue from the same traffic and conversion rate. The difference is entirely driven by AOV. This illustrates why AOV optimisation is one of the highest-leverage growth activities.
UK ecommerce benchmarks
| Industry | Typical AOV (GBP) |
|---|---|
| Fashion and apparel | £50–90 |
| Beauty and skincare | £35–60 |
| Health and supplements | £30–55 |
| Food and drink | £25–50 |
| Home and furniture | £100–300 |
| Electronics | £80–200 |
| Pet supplies | £30–55 |
These benchmarks reflect UK market data across our client base and publicly available industry reports. Your specific AOV will depend on your product pricing, range, and customer demographics.
How to improve your AOV
1. Free shipping threshold
Set your free shipping threshold 20 to 30 per cent above your current AOV. If your AOV is £45, offer free shipping at £55 to £60. This encourages customers to add more items to reach the threshold. Display a progress bar in the cart showing how close they are to free shipping.
2. Product bundling
Create bundles that combine complementary products at a small discount. A skincare brand might bundle cleanser, moisturiser, and serum as a "Complete Routine" at 10 per cent off the individual prices. Bundles increase AOV whilst providing perceived value.
3. Upselling at checkout
Show relevant product upgrades or add-ons during the checkout process. Shopify apps and Shopify Plus checkout extensibility make this straightforward to implement on your Shopify store.
4. Cross-selling via email
Use Klaviyo email flows to recommend complementary products after purchase. Cross-sell emails increase overall customer value, which improves effective AOV over time.
5. Volume discounts
Offer discounts for buying multiple units: buy 2 get 10 per cent off, buy 3 get 15 per cent off. This works particularly well for consumable products where customers will use multiple units over time.
6. Premium product positioning
Introduce a premium tier or deluxe version of your best-selling products. Even if only 10 to 20 per cent of customers choose the premium option, it lifts your overall AOV. For more on conversion optimisation, see our SEO and growth services.
Common mistakes
- Setting free shipping thresholds too high, which frustrates rather than motivates customers
- Discounting to increase AOV, which can reduce margins more than the AOV gain
- Ignoring AOV by channel — email and organic typically have higher AOV than paid social
- Not tracking AOV for new vs returning customers separately
- Focusing only on AOV without considering conversion rate impact (aggressive upselling can reduce conversion rate)
Tools for tracking AOV
- Shopify Analytics — Built-in AOV reporting in the Overview dashboard
- Google Analytics — AOV by channel, campaign, and customer segment
- Klaviyo — AOV for email-attributed orders
- Custom dashboards — Looker Studio or similar for unified AOV tracking

AOV is one of the easiest ecommerce metrics to improve and one of the most impactful. Small increases compound across every order, creating meaningful revenue growth without additional traffic or customers. Start with free shipping thresholds and product bundles, measure the impact, and iterate from there.
