AOV vs LTV, and which one to chase
Average order value is the number most stores optimise. Lifetime value is the number that decides whether the business works. Here is how they relate.
Use the LTV CalculatorWhat a customer is worth over their whole relationship with you, for repeat purchase or subscription businesses, plus what happens when retention improves.Average order value is the number most ecommerce dashboards put front and centre. It updates daily, it responds quickly to changes, and it feels like something you can act on.
Lifetime value updates slowly, needs to be calculated by hand, and does not appear on most dashboards at all.
Which is a shame, because the second one decides whether the business works.
How the two relate
AOV is not a rival to LTV. It is a component of it.
LTV = Average order value x Orders per year x Years as a customer
Order value is the first of three inputs. Improve it and LTV rises, all else equal. The phrase “all else equal” is where most of the interesting problems live.
Why AOV gets the attention
Three honest reasons.
It moves fast. Add a bundle, change a shipping threshold, put a cross-sell on the cart page, and you see the effect within a week. LTV work takes months to show up.
It is easy to measure. Every ecommerce platform reports it without you doing anything.
It feels controllable. Order value is a merchandising and pricing decision, which sits squarely inside the business. Customer lifespan feels like it depends on the customer, which is uncomfortable.
None of that is wrong. AOV work is legitimate and worth doing. It is just not where the ceiling is.
Why the ceiling matters
Look at the three inputs again and ask how far each one can realistically go.
Order value has a hard ceiling. There is only so much you can charge, only so many products a customer needs at once, only so many upsells they will tolerate before the checkout starts to feel like a fight. Most stores can improve AOV meaningfully once, perhaps twice, and then they are pushing against what customers actually want to buy.
Frequency has a ceiling too. People consume at the rate they consume. You can smooth the gaps and remind them at the right moment, but you cannot make someone need twice as much coffee.
Duration does not have a ceiling in the same way. How long someone stays in your world is, in principle, unlimited. A customer who buys for ten years is worth ten times one who stays a year. And extending it does not require a bigger product, a better website, or more ad budget. It requires being reliably present.
That asymmetry is the whole argument. Two of your three levers run out. One does not.
When raising AOV lowers LTV
This is the trap worth naming, because it is common and it is invisible on the dashboard that made you do it.
If you raise average order value by pushing harder at checkout, adding pressure, bundling things people did not want, or setting a free shipping threshold that makes customers feel worked rather than served, order value goes up and something else goes down.
The customer who was nudged into a £70 order they half-regret is less likely to come back than the customer who cheerfully spent £45. AOV rose 55 percent. If lifespan falls by more than that, LTV fell.
You will see the AOV improvement immediately and the lifespan damage six months later, by which point nobody connects the two.
The version that works is different. Selling more to people who already trust you, at the moment it is genuinely useful, raises order value without costing anything in goodwill. A post-purchase email two weeks in, leading with something useful and making the recommendation at the end, is worth more than a checkout page that argues with people.
Where to put your effort
A reasonable order of operations for most stores:
- Calculate LTV first, even roughly. Without it you cannot judge whether any of the rest is working, or how much you can afford to pay for a customer.
- Fix the first thirty days. Repeat purchase rate is the cheapest lever available and the one most stores have never deliberately worked on. It moves duration and frequency at once.
- Then improve order value, through genuine cross-selling rather than checkout pressure. Look at what your customers actually buy together and make that easier.
- Track all three inputs separately, so when LTV moves you know which lever did it.
The number to watch alongside AOV
If you only add one metric to the dashboard next to average order value, make it repeat purchase rate: the proportion of customers who buy more than once.
It is the earliest honest signal about duration. AOV tells you how well you sold today. Repeat purchase rate tells you whether you will get to sell tomorrow.
Common questions
- What is the difference between AOV and LTV?
- Average order value is what a customer spends in a single transaction. Lifetime value is what they spend across every transaction for as long as they stay. AOV is one input into LTV, alongside purchase frequency and customer lifespan.
- Should I focus on increasing AOV or LTV?
- LTV, because it is the number that determines what you can afford to spend on acquisition. AOV is worth improving, but it has a hard ceiling while customer lifespan does not.
- Does raising AOV always raise LTV?
- No. Aggressive upselling and bundling can raise order value while damaging the relationship, which shortens lifespan. If lifespan falls further than order value rises, LTV goes down.
