Free tool Cart abandonment rate calculator: rate, lost revenue, recovery
Cart abandonment rate is the share of shopping carts that never become an order: 1 − orders ÷ carts created. Enter your carts, orders and average order value to see the rate, what the abandoned carts were worth, and how much a realistic recovery rate would bring back.

Abandonment rate and what it costs
Use carts and orders from the same period. AOV, recovery rate and margin are optional and turn the rate into money.
Sessions or visitors that added at least one item to the cart.
Purchases from those carts in the same period.
Optional. Or the average value of abandoned carts, if you have it.
Optional. Share of abandoned carts you expect to win back with reminders, chat or offers.
Optional. To see recovered profit instead of revenue only.

What the abandonment numbers mean
The rate tells you how leaky checkout is; the money figures tell you whether fixing it is worth the effort.
Cart abandonment rate
75% means three of every four carts did not turn into an order. Baymard Institute's average of 50 studies published 2006–2025 is 70.22% (page updated October 2026), so most stores lose most carts. Track your own rate over time rather than chasing that figure.
Value of abandoned carts
3,000 carts × $70 = $210,000. Treat this as the size of the opportunity, not lost money: a large share of carts are wish lists and price checks.
Recovered revenue
At 5% recovery, 150 extra orders worth $10,500. Recovery comes from fixing checkout friction, reminder emails, proactive chat and better shipping information.
Recovered gross profit
At a 40% margin the recovered orders are worth $4,200 of gross profit. Compare that with what the recovery effort costs — a discount code given to every abandoner reduces it.
Cart abandonment and checkout abandonment are different rates. Checkout abandonment starts from shoppers who began checkout, so it is lower and points more directly at the checkout form.
Get the inputs from your funnel
You need two event counts from the same period.
-
1
Count carts
Sessions or users with an add-to-cart event. Decide which and keep it fixed — users give a lower count than sessions.
-
2
Count orders
Completed purchases from the same visitors in the same period. A funnel with a 7-day window handles shoppers who return later to pay.
-
3
Price the gap
Add AOV and a recovery rate you can defend from your own tests. Start low; a recovery rate guessed from a vendor's headline overstates the result.
Cart abandonment rate formula
Baymard Institute writes the formula as (1 − completed purchases ÷ carts created) × 100. Everything else on this page multiplies the abandoned carts by a value and a rate.
- Carts and orders must come from the same period and the same unit (sessions or users)
- Count orders that came from those carts; leave out orders placed without a cart, such as subscriptions renewed automatically
- For checkout abandonment, replace carts with checkouts started
- The value of abandoned carts is a ceiling; recovered revenue is the planning number
Cart abandonment rate
(1 − orders ÷ carts created) × 100%
(1 − 1,000 ÷ 4,000) = 75.0%
Abandoned carts
carts − orders
4,000 − 1,000 = 3,000
Value of abandoned carts
abandoned carts × AOV
3,000 × $70 = $210,000
Recovered revenue
value of abandoned carts × recovery rate
$210,000 × 5% = $10,500
Recovered gross profit
recovered revenue × gross margin
$10,500 × 40% = $4,200
What each point of recovery is worth
The example store: 3,000 abandoned carts a month, $70 AOV, 40% gross margin.
| Recovery rate | Recovered orders | Recovered revenue | Gross profit | New abandonment rate |
|---|---|---|---|---|
| 1% | 30 | $2,100 | $840 | 74.3% |
| 3% | 90 | $6,300 | $2,520 | 72.8% |
| 5% | 150 | $10,500 | $4,200 | 71.3% |
| 10% | 300 | $21,000 | $8,400 | 67.5% |
Recovering 5% of abandoned carts moves the rate by under 4 points, which is why the rate alone can hide a meaningful amount of revenue.
Where abandonment math misleads
Four ways to get a number that looks precise and is not.
Calling abandoned carts lost revenue
Most abandoners were never going to buy today. The full cart value is a ceiling, not a loss.
Mixing sessions and users
Carts counted per session and orders per user give a rate that is not either. Use one unit for both.
Confusing cart and checkout abandonment
Checkout abandonment starts later in the funnel and is usually lower. Say which one you report.
Discounting every abandoner
A coupon in every reminder trains shoppers to abandon on purpose. Count the discount against recovered profit.
Find the step, then talk to the shopper
Analytics and live chat share one snippet, so the funnel that shows the leak and the chat that can help see the same visitor.
Purchase funnel
View item, add to cart, checkout, purchase with a 7-day window, split by device or channel to find the step that leaks.
Learn moreProactive invites
Invite visitors automatically by page, time on page, source or cart value — for example someone idle on /checkout.
Learn moreCheckout completion as a KPI
The ecommerce template tracks begin_checkout and purchase, so checkout completion sits on the store board.

How do you calculate cart abandonment rate?
Cart abandonment rate = (1 − completed orders ÷ carts created) × 100%. 4,000 carts and 1,000 orders give 75%.
What is the average cart abandonment rate?
Baymard Institute's figure is 70.22%, the unweighted average of 50 studies published between 2006 and 2025 (page updated October 2026). Studies measure differently, so use it as context and track your own rate over time.
What is the difference between cart and checkout abandonment?
Cart abandonment starts from everyone who added to cart; checkout abandonment starts from those who began checkout. Checkout abandonment points at the form and payment step, cart abandonment at the whole path after add-to-cart.
How much revenue can I recover from abandoned carts?
It depends on why people leave and what you do. Use a recovery rate measured in your own tests — reminder emails, proactive chat on the checkout page, clearer shipping costs — and start conservatively.
Why do shoppers abandon carts?
In Baymard's survey of US online shoppers, the most common reason given (apart from just browsing) was extra costs such as shipping, tax and fees being too high. Your own funnel and paths show where it happens on your site.
Should I use AOV or abandoned cart value?
If your platform reports the value of abandoned carts, use that average: abandoned carts are often larger or smaller than completed orders. Otherwise AOV is a reasonable stand-in.

From the rate to the step that leaks
The rate says how much leaks; a funnel says where. Then decide whether chat, a reminder or a form fix is worth it.
