Cart Abandonment Rate

Cart abandonment is the share of started carts that don’t convert — one minus completed over started. Recovering even a slice of abandoned carts is high-leverage revenue.


Quick formula: abandonment from completed and started carts:
=1 - completed_purchases / carts_created
One minus completed over started carts. Industry abandonment often runs 60–80%.

The example

120 purchases from 500 carts.

The formula

The formula:

=1 - B2 / B3 // 1 − completed ÷ started

How it works

How it works:

  1. completed / carts_created is the completion rate; one minus it is abandonment.
  2. Abandonment is high by nature — 60–80% is typical across retail.
  3. The recoverable revenue is abandoned carts × their value × an expected recovery rate.
  4. Reduce it with guest checkout, clear shipping, and cart-recovery emails.

Size the prize. If 380 carts (76% of 500) abandon at an $80 average and a recovery email wins back 10%, that’s 380 × 80 × 0.10 = $3,040 recovered. Quantifying recoverable revenue turns a scary abandonment percentage into a concrete reason to invest in checkout fixes and recovery flows.

Recoverable revenue

Size the prize:

Pitfalls & errors

Define a cart. Cart-created vs checkout-started give different rates — pick one.

High is normal. 60–80% abandonment is expected; track the trend, not the absolute.

Zero carts. No carts gives #DIV/0!.
