Stop guessing prices. This offline calculator works out the shelf price that hits your target margin after marketplace fees, card fees and GST, and shows exactly what you keep.

1. Price a product. Enter unit cost, your time, shipping, platform fee % and payment fee (% + fixed). You get the shelf price (GST-inclusive if you’re registered, with .95 or whole-dollar rounding), plus profit, real margin and markup.
2. Margin ↔ markup + discount check. It ends the classic mix-up (a 50% markup is only a 33% margin) and shows how many extra sales a discount needs just to break even.
3. Bulk price list. Price your whole range at one margin and export to CSV for your website, POS or spreadsheet.

Made for Australian makers, market stallholders, online sellers and small retailers.
