How to use it

Using the cart abandonment calculator

  1. 01

    Pull cart and checkout counts

    Analytics platforms report add-to-cart events and completed transactions for any date range.

  2. 02

    Enter both numbers

    Matched periods keep the ratio honest; completed checkouts can never exceed carts created.

  3. 03

    Add AOV for the money view

    Supplying average order value converts the percentage into a dollar figure worth chasing.

Good to know

Why ~70% is the norm

Industry studies consistently place ecommerce abandonment near seven in ten carts. Hidden shipping costs, forced account creation and payment friction lead the reasons shoppers cite; all fixable without discounting.

Recoverable does not mean recoverable-in-full

The dollar estimate here is a ceiling. Recovery emails typically bring back single-digit percentages of abandoned carts; treat the number as motivation for testing, not a forecast.

Fix flow before sending coupons

Guest checkout, upfront shipping totals and more payment options address root causes. Discount-led recovery trains customers to abandon deliberately; an expensive habit to create.

How it's calculated

The math behind this calculator

Abandonment rate = (carts created − completed checkouts) ÷ carts created Recoverable revenue = abandoned carts × average order value

We subtract completed purchases from carts created to find abandonments, then divide by carts created for the rate. Multiplying abandoned carts by average order value estimates the revenue ceiling that recovery emails and checkout fixes could chase; never fully reachable, since some abandonment is window shopping.

Assumptions & limitations

  • Carts are counted per session or per person consistently.
  • The AOV projection assumes abandoned carts would have converted at your normal order value.
  • Some abandonment is intentional browsing, not fixable friction.

Worked example

With 500 carts created and only 400 completing checkout, abandonment runs at 20%; about $8,500 of estimated recoverable revenue if those 100 carts had averaged $85 orders.

FAQ

Frequently asked questions

What counts as an abandoned cart?
A session that added at least one item and left without completing purchase. Definitions vary on timeouts; pick one and measure consistently.
How effective are recovery emails?
Well-timed sequences (1 hour, 24 hours, 72 hours) commonly recover a few percent of abandonments, among the highest-converting emails you can send.
Should I show exit-intent discounts?
Test it against margin carefully. If most abandoning visitors would have returned anyway, blanket discounts simply subsidize purchases already won.
