Overview

Use this eBay Royal Mail Shipping Calculator to estimate postage for an item you sell online. Enter your sale price, packed weight, package type and delivery service to see an estimated Royal Mail shipping cost and how much of the sale price may remain after postage and optional eBay fees.

How it works

The calculator matches your parcel weight to a simplified Royal Mail pricing band based on the selected package type and service. It then estimates postage cost from that band. If you choose to include eBay fees, it calculates a percentage of the sale price and subtracts both postage and fees from the sale amount to show your estimated net proceeds.
