Numbers to enter
Enter how many people started checkout, how many completed an order and the average value of a completed order. Koala derives the drop-off rate for you.

Use the count for the same period as completed orders below.

This cannot be higher than the checkout-start count.

Finance term: AOV. Use the average value of a paid order for the same period.

Leave at 0 for no recovery assumption. If you have your own historical recovery rate or want to test a scenario, enter it here.

Koala's Calculated Result
How many checkout starts did not become orders, plus the order value attached to those abandoned checkouts at your average completed-order value.

Definition and method

What this calculator answers

Compare checkouts started with completed orders, then optionally model a recovery rate you choose instead of assuming one.

Checkout abandonment

Compare checkout sessions started with completed orders on the same matched cohort. The difference is abandoned checkouts under this calculator’s definition.

Worked example: your figures

The interactive result above is the worked example. Change any input and the same deterministic engine recomputes the answer; this page does not insert a generic example business or silently treat example values as a benchmark.

  • No market benchmark or outcome is silently inserted by this page.

Frequently asked questions

What is cart abandonment?

Use the calculator result for the inputs entered and keep any market-response or operating recommendation separate from the deterministic calculation. Support that additional assumption with the business’s own evidence or an explicitly labelled scenario.

Where does the biggest leakage happen?

Use the calculator result for the inputs entered and keep any market-response or operating recommendation separate from the deterministic calculation. Support that additional assumption with the business’s own evidence or an explicitly labelled scenario.

What lifts the abandonment rate?

The cheapest lifts come from trust signals (reviews, return policy, secure-checkout badge), showing shipping costs early, and a recovery email 1–2 hours after abandonment. Each one tightens the funnel by 1–3 percentage points for small stores.

How do I estimate the recovery ceiling?

There is no universal numeric benchmark for this decision. The right comparison depends on the industry, geography, business model, time period and exact metric definition. Use the business’s own history, economics and explicit target unless a verified benchmark matching that scope is available.
