Account Health Metrics Explained: ODR, LSR, PFCR and How to Stay Green
# Account Health Metrics Explained: ODR, LSR, PFCR and How to Stay Green
Your Amazon account health determines whether you stay in business. Three metrics—Order Defect Rate, Late Shipment Rate, and Pre-Fulfillment Cancel Rate—form the foundation of Amazon's seller evaluation system. Fall below their thresholds, and you face listing suppression, account suspension, or permanent removal from the platform.
Understanding what these metrics measure, how Amazon calculates them, and what actions keep them green isn't optional. It's survival.
Order Defect Rate: The Most Critical Metric
Order Defect Rate measures the percentage of orders with one or more defects over a rolling 60-day window. Amazon sets the threshold at less than 1%. Exceed this, and your account faces immediate risk.
Three components contribute to ODR:
Negative feedback rate counts any feedback rating of one or two stars. This includes product complaints, shipping issues, and customer service problems—regardless of whether the issue was your fault.
A-to-Z Guarantee claim rate includes all claims where Amazon granted the claim or you refunded the customer directly. Even claims you win sometimes count during the investigation period.
Chargeback rate covers credit card disputes filed by customers through their banks rather than through Amazon's system.
The math is straightforward: total defective orders divided by total orders. Sell 500 items and receive 6 negative feedback ratings, and your ODR hits 1.2%—above the threshold.
What makes ODR dangerous is its cumulative nature. A single bad week compounds across the 60-day window. Sellers with lower volume feel the impact harder; five defects on 200 orders creates a 2.5% ODR, while the same five defects on 2,000 orders produces just 0.25%.
Late Shipment Rate: The Fulfillment Deadline Metric
Late Shipment Rate tracks orders confirmed shipped after the expected ship date. Amazon requires this metric stay below 4%.
The calculation uses a 10-day or 30-day window depending on your view. Amazon looks at orders where you confirmed shipment late divided by total orders you fulfilled yourself during that period.
FBA sellers don't worry about LSR—Amazon handles fulfillment and takes responsibility for shipping timelines. Merchant-fulfilled sellers carry full responsibility.
Common LSR problems stem from:
The ship confirmation timestamp matters, not the actual delivery. If you hand packages to your carrier on time but forget to confirm shipment in Seller Central until the next day, those orders count as late.
Pre-Fulfillment Cancel Rate: The Inventory Accuracy Metric
Pre-Fulfillment Cancel Rate measures orders you cancel before shipment. Amazon sets this threshold below 2.5%.
This metric reflects inventory management accuracy. When you list items you can't fulfill—whether from stockouts, listing errors, or pricing mistakes—and then cancel customer orders, PFCR rises.
Buyer-requested cancellations don't count against you. Only seller-initiated cancellations impact this metric.
High PFCR typically indicates:
The 7-day rolling window means recovery happens faster than ODR, but repeated issues create patterns Amazon notices beyond the single metric.
Staying Green: Practical Prevention Strategies
Monitor daily, not weekly. Account Health Dashboard updates continuously. Catching problems at three defects instead of eight gives you room to correct course.
Request feedback removal proactively. Amazon removes feedback that violates guidelines—comments solely about the product (not the seller), obscene language, or FBA fulfillment complaints. Submit removal requests immediately when eligible.
Set realistic handling times. If your operation needs two business days to process and ship, don't promise one-day handling. The competitive pressure isn't worth the LSR damage.
Confirm shipments the moment carriers take possession. Automate this process through shipping software integration. Manual confirmation introduces human delay and error.
Maintain inventory buffers. Running out triggers cancellations. A 15% safety stock buffer costs less than account suspension.
Respond to A-to-Z claims within 48 hours. Provide tracking information, delivery confirmation, and any communication records. Amazon favors sellers who engage the process with documentation.
Use FBA for high-risk periods. Prime Day, Q4 holidays, and any promotional period increases order volume. Shifting to FBA during peaks eliminates LSR and PFCR exposure when stakes run highest.
