EU selling margin calculator
Compare unit contribution and break-even price using your own product, shipping and fee inputs.
Inputs stay in your browser. Save is optional; keep your own backup.
This organizes entered information; it does not certify a product, verify a live listing, appoint a responsible person or replace a product-specific assessment.
Quick answers
Can I start free?
Yes. The seller tools run without an account. The product check and catalog use the existing account flow.
Does this guarantee compliance or reinstatement?
No. Outputs organize seller-supplied information. Product-specific duties, evidence and marketplace acceptance still need review.
Next step
Start with the free check. Payment happens only through the existing checkout; the paid pack does not provide certification, testing or an EU Responsible Person.
