Average Order Value Calculator
Work out your AOV from revenue and orders — then model what a small increase would be worth in extra revenue, extra profit, and a higher ad cost you can afford per order.

The AOV formula
AOV = Revenue ÷ Orders · Extra revenue = AOV × Increase % ÷ 100 × Orders
Average order value is the revenue of a period divided by the number of orders in that same period. It answers one question: how much does a customer spend per checkout? Because it is an average, a single unusually large order can pull it upwards — if you sell at very different price points, look at your order distribution as well, not just the average.
The second half of the line is the projection. Lifting AOV by a given percentage lifts every order by that percentage, so the extra revenue is your current AOV times the increase times the number of orders. Multiply that by your margin before ad costs and you get the extra profit — the number that decides whether the change is actually worth building.
How to use this calculator
- 1
Enter the revenue of one clear period — last 30 days, last month, or a single campaign — and use the same definition every time you check.
- 2
Enter how many orders produced that revenue in the same period. Orders, not units sold and not sessions.
- 3
Optionally add your margin before ad costs and the AOV increase you want to model — the calculator then shows the extra revenue and the extra profit that increase would produce.
Why AOV is the most underrated lever in paid traffic
Most beginners try to fix profitability by pushing their cost per acquisition down. But CPA is decided in an auction you do not control — you are bidding against everyone else buying the same attention, and their budgets move your price. AOV is decided inside your own store, on your product page and in your cart, where nobody bids against you.
The chain is short. A higher AOV means a bigger contribution margin per order, and your break-even cost per order is exactly that contribution margin. If an order carries 30 dollars of margin, you can pay up to 30 dollars to win it and still break even. Lift AOV so the order carries 40, and the cost you can afford moves to 40 with it.
That is why AOV changes what is possible, not just what is profitable. Audiences, placements and campaigns that were slightly too expensive suddenly clear the bar, and you can keep buying traffic at a price your competitors cannot match. Model the increase here, then put the new number into the CPA calculator to see your new ceiling.
How stores actually raise AOV, ranked by effort
The cheapest change is a quantity offer: two or three of the same product at a better unit price. It needs no new supplier, no new creative and no new landing page. It works best on consumables, on products people buy for more than one person, and on anything where running out is annoying.
Next come complementary cross-sells at the cart — an accessory that genuinely belongs with the main product, not a random second item — and a free-shipping threshold placed just above your current AOV, close enough that customers feel it is reachable. Premium variants take the most work, because a bigger size or a better version means new supply and new photography, but they lift AOV without giving away a cent of discount.
The trap is the discount-driven bundle. A three-for-two offer can raise AOV and shrink profit per order at the same time, because you are buying the bigger cart with your own margin. That is exactly what the profit projection here exposes: enter the margin you would have after the discount, not the margin you have today, and check whether the extra revenue still leaves anything behind.
Frequently asked questions
What counts as revenue when I calculate AOV?
The usual convention is net product revenue: what customers paid for the goods, before shipping charges and taxes, after discounts and refunds. What matters more than the convention itself is consistency. If you include shipping income one month and exclude it the next, your trend is meaningless — pick one definition, write it down, and pull the same report from your store every time.
Should I optimise AOV or customer lifetime value?
AOV measures a single checkout; lifetime value measures everything one customer spends over the whole relationship. If you sell one-off products and buy most of your traffic from ads, AOV drives your daily decisions, because the first order has to carry the ad cost on its own. If you sell consumables or run subscriptions, lifetime value is what you should really be bidding against — but AOV still tells you how quickly that first order pays you back.
Is a higher AOV always better?
No. AOV is revenue per order, and revenue is not profit. A discount bundle can raise AOV while lowering the margin on every order, and a heavier or bulkier bundle can raise your shipping cost too. Judge every change on contribution margin per order rather than on AOV alone — that is why this calculator projects profit and not just revenue.
How does AOV change my break-even CPA?
Your break-even cost per order is the margin an order still carries after product cost, shipping and payment fees. Raise AOV while keeping the same margin percentage and that figure rises with it, so you can afford to pay more for each customer. Run the new AOV through the CPA calculator to see the new affordable cost per order, and through the BEROAS calculator to see the lower return on ad spend you now need to break even.
