Where your computed ODR sits relative to the 1% limit many marketplaces apply. The exact threshold and the defects that count differ by platform and change over time, so treat these bands as orientation and confirm the current rule and rolling window in your seller policy.
Range
What it typically means for account standing
Under 0.5%
Comfortable buffer below the common 1% limit; healthy standing with room for a short-term spike.
0.5% – 1%
Inside the limit but with little slack; watch closely, as a few more defects can breach it on low volume.
◀ your ODR (0.80%)
1% – 2%
At or above the common threshold — many platforms flag this band, risking warnings or listing suppression.
Above 2%
Well over the typical limit; serious account-health risk, including possible suspension on some marketplaces.

What it calculates: Order Defect Rate, Within 1% Threshold, Defect-Free Orders.
Amazon and several other marketplaces require sellers to keep order defect rate below 1%. Crossing it triggers warnings and, if sustained, suspension of selling privileges — which is why the calculator reports whether you are inside the threshold rather than just the percentage.
order defect rate = (defective orders / total orders) × 100
The consequence is what makes this different from an ordinary quality metric. A 1.2% defect rate is not slightly worse than 0.9%; it is on the wrong side of a line that can stop the business trading.
Negative feedback, an A-to-z claim, or a service chargeback
A defect is an order that received negative feedback, an A-to-z guarantee claim, or a credit card chargeback for service reasons. One order carrying two of those still counts once.
Note what is absent: an ordinary return is not a defect. A customer returning an item through the normal process, however annoying, does not affect this metric at all — only orders where the customer escalated do.
At 50 orders a month, one complaint is a 2% rate
The arithmetic is brutal for small sellers. A single negative feedback on 50 orders puts you at 2%, double the threshold, from one unhappy customer. At 5,000 orders the same complaint is 0.02%.
This is why new and seasonal sellers get suspended more often than their actual quality warrants. Marketplaces apply minimum-order thresholds before enforcing, but the exposure while volume is low is real and worth planning around.
By the time the rate rises, the orders are already shipped
Defects arrive weeks after the orders that caused them, so a rate that has risen is reporting a problem that happened last month. Watching it alone means always reacting late.
The leading indicators are late shipment rate, stockouts causing cancellations, and support response time. Fixing those moves the defect rate a month later; fixing the defect rate directly is not something you can do.
Frequently Asked Questions
What counts as a defective order?
Typically an order with negative feedback, a service or A-to-z guarantee claim, or a chargeback. Exact definitions vary by marketplace, so check your platform’s current policy for what it includes.
What is a good order defect rate?
Many marketplaces require ODR below 1%, and lower is better. Staying well under the threshold gives you a buffer against short-term spikes on low order volume.
Why do marketplaces require ODR under 1%?
ODR is their proxy for buyer experience. Keeping it low protects shoppers and the platform’s reputation, so accounts that exceed the limit can face warnings, suppression, or suspension.
How is ODR different from return or refund rate?
Return and refund rates measure orders coming back or being refunded. ODR measures orders that triggered a negative buyer experience signal, so an order can be returned without being a defect, and vice versa.
How can I lower my order defect rate?
Improve product quality and accuracy, ship on time, respond quickly to buyer messages, and resolve issues before they become claims or chargebacks. Fast, fair service is the most direct lever.
Does a single defect on low volume hurt a lot?
Yes. On small order counts one defect can push ODR above 1%, which is why new or low-volume sellers should be especially careful. Volume smooths the rate over time.
