Use this calculator before setting a OnBuy price in United Kingdom

Sellers often lose margin through small costs that are easy to miss: payment fees, marketplace commission, shipping gaps, advertising spend, returns, packaging, and tax reserves. This page gives a quick planning model in GBP so you can compare products before listing or scaling ads.

SEO-ready pricing workflow

  1. Enter a realistic sale price and landed product cost.
  2. Add shipping cost, ad cost per order, and a return reserve.
  3. Check whether net margin stays positive after fees and tax reserve.
  4. Compare the same product across related marketplaces and countries.
