Order Defect Rate (ODR) Calculator

The ODR is the number that ends accounts. Amazon says keep it under 1%, and they mean it — cross that line and the dreaded "Your account has been deactivated" email stops being a myth and becomes your inbox. This calculator tells you exactly where you stand before that happens.

You need two numbers: total orders in the last 60 days, and defective orders (negative feedback plus A-to-z claims plus chargebacks). Divide the second by the first. That's your ODR.

The 60-day trap

Here's what nobody tells new sellers: ODR is a rolling 60-day window, not a monthly snapshot. A horrible week of late shipments and two angry chargebacks doesn't vanish at month-end. Those defects sit in your rate for two full months, quietly pulling the average up while you've already moved on. I've watched sellers relax because "this month was clean" and then get flagged on defects from six weeks prior.

One claim is enough

The cruel part for low-volume sellers: a single A-to-z claim on 200 orders is 0.5%. Two is 1%. You're suspended on the strength of one unhappy customer. High-volume sellers get buffered by scale; if you're doing 50 orders a week, every defect is expensive. Watch this number weekly, not quarterly.

What to do if you're over

Don't panic-cancel. Do the actual work: find why the claims happened (late ship? wrong item? fake tracking?) and fix that. Then write the reinstatement plan if Amazon asks for one — and they will ask for one, in writing, with specifics. A vague "we will do better" gets rejected.

The takeaway: ODR is the one metric where ignorance is genuinely dangerous. Run this weekly. Know your distance to the line the way you know your bank balance.
