Cart abandonment rate calculator
Cart abandonment rate is the share of shopping carts that never turn into an order. Enter the carts created and the purchases completed in a period. Add your average order value to see the revenue left in abandoned carts, and a recovery rate to see what reminder emails or a smoother checkout could bring back.

How to use it
- Enter the carts created and purchases completed for a period.
- Optionally enter your average order value and the share of abandoned carts you think you could recover.
- Read the abandonment rate, the abandoned carts and the revenue figures.
- Abandoned carts = carts created − purchases completed
- Cart abandonment rate = abandoned ÷ carts × 100
- Completion rate = purchases ÷ carts × 100 = 100 − abandonment rate
- Value of abandoned carts = abandoned × average order value
- Recovered revenue = abandoned × recovery rate × average order value
Worked example
1,000 carts, 300 orders, average order 60, and you expect to recover 10% of abandoned carts:
- Abandoned carts 700, abandonment rate 70 %, completion rate 30 %.
- Value of abandoned carts 700 × 60 = 42,000.00.
- Recovering 10% brings 70 orders and 4,200.00 of revenue.
Tips
- Track the rate by device: mobile checkouts often lose more carts than desktop ones.
- Look at where in the checkout people leave: the shipping step, account creation or payment.
- Reminder emails can only reach shoppers who left an email address, so the realistic recovery rate is limited by that.
Frequently asked questions
How is cart abandonment rate calculated?
Cart abandonment rate = (1 − completed purchases ÷ carts created) × 100. With 1,000 carts and 300 orders, 700 carts were abandoned: a 70% rate.
Is the value of abandoned carts lost revenue?
It is an upper bound. Many shoppers use the cart to compare prices or save items for later and would not have bought anyway. The recovery rate is a more realistic way to estimate what you can win back.
What counts as a cart?
Usually a session in which at least one product was added to the cart. Use the same definition as your analytics tool, and count orders from the same sessions or period.
How can I lower cart abandonment?
Common fixes are showing shipping costs early, allowing guest checkout, offering familiar payment methods, keeping the checkout short and sending a reminder email to shoppers who left a cart.
