Amazon Account Health Calculator

How to use the Amazon account health calculator

The Amazon account health calculator lets you check in seconds whether your current numbers fall within the basic thresholds for sellers. The tool runs locally in your browser — you do not create an account, you do not send any data, and you do not upload any files.

Here is how to use it:

1. Enter four percentages: order defect rate (ODR), late shipments, pre-fulfillment cancellations, and valid tracking numbers.
2. The fields come pre-filled with sample numbers: 0.8, 3, 1.5, and 97. Overwrite them with your own data from your account reports.
3. For each metric you will see its name, its target, your value as a percentage, and whether the condition is met.
4. At the bottom, check the combined "Basic account health thresholds" summary with a result of "met" or "not met".

You will get the most out of the calculator when you enter data from the most recent period and compare it with results from a few weeks earlier — you will quickly see whether any area needs attention before it gets close to the line.

How to read ODR, late shipments, cancellations, and VTR

All four metrics describe the quality of your order handling, but each one looks at a different part of the process.

• Order defect rate (ODR) — the share of orders that ended with a problem for the buyer, such as negative feedback, a claim, or a chargeback. The lower the number, the better.
• Late shipments — the percentage of orders shipped after the delivery date you promised the buyer in your own handling time. A value that is too high usually means you are promising too much or that you have a problem packing orders and handing them to the carrier.
• Pre-fulfillment cancellations — orders cancelled by the seller before the package was shipped. The most common causes are stockouts and inaccurate inventory counts in your listings.
• Valid tracking numbers — the share of shipments that require tracking and have a correct tracking number. The logic here is reversed: the higher, the better.

These numbers are best read together. A single metric close to the threshold does not have to mean trouble, but when several are moving in the wrong direction at the same time, it is worth looking at your inventory, your handling times, and how you handle claims before the problem becomes permanent.

Amazon account health thresholds and what they mean

The calculator compares your values against four basic thresholds. The table below shows them together with the result you get for the default values.

For these values the summary reads "Basic account health thresholds: met", because all four conditions are true. But if even one metric falls outside its threshold, the overall result changes to "not met".

Keep the direction of the comparison in mind: for the first three metrics the value has to be lower than the threshold, and for valid tracking numbers it has to be higher. The thresholds are strict, so a value exactly on the line, for example an ODR of 1.00%, is not considered met.

Treat the result as a signal to act on, not as a final verdict on your account. Even when everything is within the thresholds, it is worth checking these numbers regularly — that way you spot a decline before it becomes serious.

How Seller Fulfilled Prime differs from the basic metrics

Seller Fulfilled Prime is a program in which you ship orders yourself but commit to a service standard close to Prime. It comes with stricter, separate requirements than the basic thresholds this calculator checks. The tool does not analyze them — in the results you will see a permanent note that SFP follows its own rules, including on-time delivery, and that you need to verify them in Seller Central.

The practical takeaway is simple: a "met" result means your metrics fall within the basic thresholds, not that you qualify for Seller Fulfilled Prime. Those are two different things, even though they overlap in part.

If you are considering joining SFP, treat the calculator as a starting point and a quick check of the four most important numbers. You will find the full list of criteria, deadlines, and how they are measured in Seller Central — the only current source.

Tool limitations and what it does not calculate

The calculator is deliberately simple: it checks four metrics against the basic thresholds and nothing else.

• It does not calculate fees, commissions, shipping costs, taxes, or margins.
• It does not convert amounts or currencies. Amounts on Amazon are listed in the currency of each marketplace, often in US dollars ($), but here you work only with percentages, so the currency does not affect the result.
• It does not check on-time delivery or the remaining Seller Fulfilled Prime requirements — that is a separate set of criteria.
• It does not assess full eligibility for selling programs, it does not analyze account history, and it does not predict Amazon decisions.
• It does not take into account the individual terms of your agreement or current pricing. You can change the values you enter as you like, and you should treat the thresholds themselves as a guide and check their current wording in Seller Central.
• It does not pull data automatically — you enter it yourself, so the result depends on how current the numbers you provide are.

That is why the result is indicative and best used as a quick check before a deeper analysis in your seller dashboard. It does not replace reports, Amazon policies, or an individual assessment of your situation.

Frequently asked questions

The result is based on the fixed thresholds built into the tool; Amazon requirements can change, so check the current rules in Seller Central before making a decision.
