The Etsy Keep Calculator is free. It is not the £12 Keep Pack. The calculator estimates fees in the browser. The Keep Pack is the paid worksheets.

Payments are one-off. There is no subscription. Stripe takes the card payment. This site does not store the full card number.

Atelier Keep is not affiliated with Etsy. Figures on the calculator are estimates. Email hello@atelierkeep.com.
