Cost of goods, quietly worked out
Calculator · GST-aware

Cost of goods & margin calculator.

For a single SKU or menu item. Enter your sale price and your direct cost lines — landed cost, packaging, freight-in, labour by the minute, and card or marketplace fees. COG splits the GST at 10%, and shows the margin honestly.

This SKU

GST assumed at the Australian 10% rate. Card & merchant fee is a percent of net sale — typically 1.75% for Shopify Payments AU, 2.6–2.9% for Square, or 4–6% for Afterpay. On landed-cost items, freight-in should include inbound freight, duty on the customs value and any brokerage fees.

Note on GST If you're registered for GST in Australia (turnover above the $75,000 threshold), remit the 10% GST portion from your sale price to the ATO on your quarterly BAS — it's not yours to margin against. Divide by 11, not by 1.1. COG defaults to GST-inclusive display because most POS systems, menu boards and Shopify checkouts work that way. Toggle to GST-exclusive for wholesale price lists, tax invoices and cost-of-goods reports.
