Revenue lost to abandoned carts. The Cart Abandonment Loss Calculator takes carts started, carts abandoned, average order value, share you could realistically recover and returns revenue left in abandoned carts plus abandonment rate, recoverable with reminders. Results update as you type, and the formula is shown under the result so you can repeat it in your own spreadsheet.
Online and retail margins are decided by the costs that are easy to forget: fees, shipping, returns, storage and advertising. Fill in every line, even with an estimate, before deciding what to sell and at what price. Use the worked example below to check the maths against your own figures.
How the Cart Abandonment Loss Calculator works
Typical abandonment is around 70%. Recovering even a tenth of it with reminder emails, saved carts and clearer shipping costs is usually the cheapest revenue in e-commerce.
