Amounts are in €. Each unit you restock also pays Amazon Ireland's fulfilment fee when it sells; these are the figures fba.tools uses.
| Size tier | Fee |
|---|---|
| Small envelope | €2.18 |
| Standard envelope | €2.65 |
| Small parcel | €3.04 |
| Standard parcel | €4.27 |
| Large parcel | €5.84 |
| Extra large | €10.07 |
Amazon changes its fees from time to time, and some categories have tiered rates or minimum fees. Confirm the rate for your category in Seller Central before you rely on it.
Going out of stock on Amazon is one of the most damaging operational mistakes an FBA seller can make. Amazon's algorithm factors in consistent availability, and products that go out of stock lose keyword ranking — which can take weeks to recover. A single stockout on a high-velocity product can cost thousands in lost sales and ranking recovery costs.
The restock calculator computes your reorder point based on your actual sales velocity and your supplier's lead time, with a configurable safety stock buffer. Set a calendar reminder to check this every week and you'll avoid stockouts permanently.
