Markup Calculator for Australian Retailers
If you’re a retailer operating in Australia, one of the most important decisions you’ll make is setting the right price. Price too low and your profits disappear. Price too high and customers walk away.
That’s why we built this free markup calculator for Australian retailers — simple, accurate, and GST-correct.
This calculator works out your selling price, markup, margin, profit, and GST in a clear and simple way. No finance degree required.

Markup Formula (Simple Explanation)
This is the basic formula used by Australian retailers:
Markup (%) = (Selling price − Cost price) ÷ Cost price × 100
Example:
Cost price: $50
Selling price: $70
Profit: $20
Markup = 40%
Cost price: $50
Selling price: $70
Profit: $20
Markup = 40%
Formula for Selling Price
Selling price = Cost price × (1 + Markup ÷ 100)
Example:
Cost price: $50
Markup: 40%
Selling price: $70 (ex GST)
Cost price: $50
Markup: 40%
Selling price: $70 (ex GST)
