ODR (Order Defect Rate)
The percentage of orders with a negative review, A-to-z claim or chargeback - marketplaces suspend accounts that exceed their threshold.
In practice
Amazon calculates ODR over a rolling 60-day window, and because even a small number of orders can push the rate above the 1% threshold for newer or lower-volume sellers, it's one of the most closely watched health metrics for avoiding account suspension.
A seller with 200 orders in 60 days gets 3 negative reviews and 1 chargeback flagged as defects - a 2% ODR, above the typical 1% threshold.
Why it matters
Because ODR is calculated on a rolling window with a low absolute threshold, a newer or lower-volume seller can be pushed over the limit by just a handful of bad orders.
Worth knowing
- Calculated over a rolling 60-day window on Amazon, not a lifetime average.
- Negative reviews, claims, and chargebacks are the three components typically counted as defects.
- Consistently exceeding the threshold can lead to account suspension.
