A plain arithmetic estimate of what abandoned checkouts add up to in your store each month — from your own numbers, with the formula shown. No signup, nothing stored.
Default of 70% is based on the Baymard Institute's meta-analysis of published studies — edit it if you know your store's own rate.
These rows are arithmetic illustrations, not predictions — actual recovery depends on your audience, channels, timing, and offer.
orders = sessions × conversion rate checkouts started ≈ orders ÷ (1 − abandonment rate) abandoned checkouts = checkouts started − orders abandoned value = abandoned checkouts × average order value
Caveats: this treats every abandoned checkout as carrying one average order, ignores seasonality, and assumes your abandonment rate applies uniformly. Treat the output as a rough order of magnitude. Note that only checkouts where the shopper entered contact details can be followed up by email — see when Shopify creates an abandoned checkout.
