How the Package Weight Calculator works
Carriers charge on the weight of the whole parcel, not the product. The box, void fill, tape and documentation all add up — and because rates step at weight bands, a few hundred grams of unnecessary packaging can push a shipment into the next band and cost real money.
Not financial advice. Marketplace fees change, and they vary by country, plan and seller status. Every rate here is an editable default, not a quoted price — check the platform's current fee schedule before you price a product against it. This is not tax or business advice.
Frequently asked questions
What is the difference between net and gross weight?
Net weight is the product alone. Gross weight is everything the carrier lifts — product, box, protective material and labels. Rates are always based on gross.
How much does packaging typically add?
A small corrugated box is 100-300 g; void fill adds 50-200 g; a padded mailer is 20-60 g. On a light product, packaging can be a third of the billable weight.
Why do weight bands matter so much?
Because pricing steps rather than climbs smoothly. A parcel one gram over a band boundary pays the whole next band. Weighing before you finalise packaging is worth doing for anything shipped in volume.
How do I reduce package weight?
Lighter void fill such as paper or air pillows instead of heavy foam, right-sized boxes needing less fill, and mailers rather than boxes where the product tolerates it. Check dimensional weight too — the lightest option is not always the cheapest.
