About the Shipping Cost Calculator
Shipping is where sellers lose money without realising it, because carriers often bill by dimensional (volumetric) weight — a formula based on a parcel's size, not just how heavy it is. A big, light box can cost far more to ship than its actual weight suggests.
This Shipping Cost Calculator estimates cost using dimensional weight, the way real carriers bill, so your postage charges cover what you actually pay.

How the Shipping Cost Calculator works
These calculators use the standard, published fee structures of the major marketplaces and platforms — Shopify, Amazon FBA, Etsy and eBay — including referral, transaction, payment-processing and fulfilment fees. By combining those with your product cost and price, they show your real profit and margin per sale rather than just revenue.
All calculations run privately in your browser.
Tips & best practices
- Carriers charge on whichever is greater — actual or dimensional weight — so a big light box can cost more than a small heavy one.
- Use packaging no larger than needed; trimming box size directly cuts dimensional weight and cost.
- Confirm the divisor your carrier uses for volumetric weight, as it varies between couriers.
Standards & accuracy
Based on the published fee structures of Shopify, Amazon, Etsy and eBay for realistic seller estimates.
Marketplace fees vary by plan, category and country and change over time, so treat results as close estimates. Confirm the exact figures against your own seller account before making decisions.

Frequently asked questions
