One number can suspend your account on its own. Amazon tells you about it after it is too late.

Key takeaways

• ODR combines negative feedback, A-to-z Guarantee claims and service chargebacks into one percentage on a rolling 60-day window. Reporting describes it as the single most consequential metric Amazon tracks.
• The published threshold is 1%. Reporting says an early-warning flag fires around 0.8%, top sellers hold below 0.3%, and notifications are reactive — arriving after you cross, not at 0.7% while you are trending.
• Only 1-star and 2-star feedback counts. A 3-star rating is neutral. And multiple negative signals on the same order count as one defect, not two.
• A-to-z claims count whether granted or not, according to one source — which makes preventing the claim more valuable than winning it.
• The Account Health Rating starts at 200. Reporting puts 200+ as healthy, 100 to 199 as at risk, and below 100 as capable of triggering suspension.

Every metric Amazon publishes has a threshold. This one is different in two ways: reporting describes it as capable of suspending an account on its own, regardless of how everything else looks, and the warning system is described as telling you after the fact.

01What counts as a defect

Three signals, on a rolling 60-day window:

• Negative feedback — only 1-star and 2-star. A 3-star rating is neutral and does not count
• A-to-z Guarantee claims filed against you — reported by one source as counting whether granted or not
• Service chargebacks

Multiple negative signals on the same order count as one defect, not two or three. A buyer who leaves 1-star feedback and files an A-to-z claim on the same order produces one defect.

Note also that since August 2025, reporting states buyers can submit star-only ratings with no written comment — which means a defect can appear with no explanation attached and nothing to diagnose from.

02The small-seller problem

This is the structural point nobody states plainly.

ODR is a percentage, and on a rolling 60-day window. At low order volume, each defect carries far more statistical weight.

At 1,000 orders in 60 days, one defect is 0.1%. At 100 orders, one defect is 1% — the threshold, from a single unhappy customer. Reporting notes this directly: a string of negative reviews from a bad batch can push ODR past 1% inside a week, especially for sellers with low order volume.

Which means new and small sellers are structurally more exposed to this metric than large ones, and the standard advice to “keep ODR low” is not equally achievable at every scale. The practical response is not better averages — it is preventing individual defects, because at low volume each one matters.

03The warning problem

Reporting describes the notification system as reactive: you get an alert after your ODR exceeds 1%, not when it is trending toward it at 0.7%.

The metric moves on a 60-day window, so by the time the alert arrives, the defects causing it are up to two months old and there is nothing to undo. The window is described as short enough that a bad week of holiday orders can spike your rate before you have time to react.

The answer is your own monitoring, at a cadence Amazon does not provide. One published routine takes under fifteen minutes a week:

1. Account Health dashboard daily — two minutes
2. Feedback Manager weekly for new negative entries
3. A-to-z claims immediately — do not let them auto-grant
4. Track which SKUs generate defects

That fourth item is the one that changes outcomes. Reporting describes tracking defect-generating SKUs as the fastest way to lower ODR, because defects cluster by product rather than distributing evenly.

04Preventing the claim rather than winning it

If A-to-z claims count whether granted or not, defending a claim successfully still leaves the defect.

Reporting describes A-to-z claims as following a predictable pattern — shipment delayed, seller unresponsive, buyer escalates — that can be interrupted before it reaches the claim stage.

Two things follow.

Respond to buyer messages within 24 hours. Reporting describes this as directly affecting ODR and being tracked, rather than being a courtesy standard.

Refund proactively before a claim is filed. Reporting is explicit: a proactive refund prevents the claim existing in your ODR at all. On a $25 item, refunding to avoid a defect is cheap insurance — particularly at low order volume where one defect is a large percentage.

That is an uncomfortable conclusion for anyone who believes in defending the position, and it is the arithmetic.

05Feedback removal

Reporting describes Amazon automatically removing feedback that:

• Contains a product review rather than seller experience feedback
• Contains abusive language
• For FBA orders, complains about shipping that was Amazon’s responsibility

Buyers also have 60 days to remove feedback themselves.

That third category is worth knowing. An FBA seller receiving negative feedback about late delivery has grounds, because Amazon shipped it. Reviewing negative feedback for removable entries is a legitimate and reasonably quick task.

06Account Health Rating

Reporting describes the AHR as consolidating compliance into one score:

Score	Status
200+	Healthy — where a new account starts
100–199	At risk
Below 100	Can trigger suspension

It is calculated across customer service performance, policy compliance and shipping performance for merchant-fulfilled orders.

Two operational notes from reporting. Pulling an ASIN without addressing the underlying violation is described as the most common mistake — it leaves the point deduction in place. And delayed responses to violations can result in additional deductions, so a Plan of Action submitted within 24 hours is better than a better one submitted next week.

07The other metrics, briefly

Metric	Reported threshold
Order Defect Rate	Below 1%
Late Shipment Rate	Under 4% — two consecutive months above typically triggers a notification
Valid Tracking Rate	Above 95%
Cancellation Rate	Amazon-set
On-Time Delivery Rate	Reported as tightened for Prime-eligible sellers in early 2026
Feedback rating	Aim 95%+; below 90% reported to affect Buy Box win rate

For FBA-only sellers, reporting notes Amazon handles the shipping metrics, so ODR and policy compliance dominate. That is one genuine argument for FBA that does not appear in fee comparisons — see the FBA against FBM guide.

Reporting also links feedback to the Buy Box: during high-traffic periods, sellers rated 4.5 stars or above are described as winning the Buy Box roughly 79% of the time, with a drop below 4.3 affecting it. See the Buy Box guide.

08What to do

Check the Account Health dashboard daily. Two minutes, and it is the only early warning that exists.

Set your own alert level at 0.5%, not 1%. The published threshold is the cliff edge, not the target.

Respond to buyer messages within 24 hours, without exception.

Refund before a claim is filed where the amount is small relative to the cost of a defect.

Track defects by SKU. They cluster, and one product usually explains most of them.

Review negative feedback for removable entries — product reviews, abusive content, and FBA shipping complaints.

If you are above 0.8%, stop everything else. Reporting’s own prioritisation is to audit the last 60 days of claims, feedback and chargebacks before working on anything else. It is the one metric that suspends an account by itself.

Frequently asked

What is a good Order Defect Rate?

The published threshold is below 1%. Reporting describes an early-warning flag around 0.8% and top sellers maintaining below 0.3%. Treat 1% as the cliff edge rather than the target.

Does a 3-star review count against me?

No. Only 1-star and 2-star feedback counts toward ODR. A 3-star rating is neutral.

Do A-to-z claims count if I win them?

One source states claims count whether granted or not. That makes preventing the claim — through fast responses and proactive refunds — more valuable than defending it.

Why did I not get a warning before crossing the threshold?

Reporting describes notifications as reactive: the alert arrives after ODR exceeds 1%, not while it is trending at 0.7%. Your own daily monitoring is the only early warning available.

Why is ODR harder for small sellers?

It is a percentage on a 60-day window. At 100 orders, a single defect is 1% — the threshold. At 1,000 orders it is 0.1%. Low volume means each defect carries far more weight.

Can negative feedback be removed?

Reporting describes Amazon automatically removing feedback that is a product review rather than seller feedback, contains abusive language, or — for FBA orders — complains about shipping that was Amazon's responsibility. Buyers can also remove their own within 60 days.
