About the Discount & Markup Calculator
A Discount & Markup Calculator Australia helps businesses determine the correct selling price, discount amount, and final price after markups or markdowns. Getting pricing right is one of the most critical decisions a business owner makes. Price too high and you lose sales to competitors. Price too low and you erode your margins and may even sell at a loss. Australian businesses from Perth to Hobart use discount and markup calculations daily for retail pricing, wholesale pricing, promotional campaigns, and end-of-season sales. The ATO does not prescribe pricing methods, but accurate record keeping of cost prices and selling prices is essential for tax compliance.
What is the Discount & Markup Calculator?
The Discount & Markup Calculator is a versatile financial tool that performs four essential pricing calculations: markup from cost to selling price, margin from cost to selling price, discount from original price to sale price, and the reverse calculation of original price from discounted price. Markup is the amount added to the cost price to arrive at the selling price, expressed as a percentage of the cost. Margin (also called gross profit margin) is the difference between the selling price and the cost, expressed as a percentage of the selling price. Understanding the relationship between markup and margin is crucial because they are not the same. A 50% markup on cost gives a 33.3% margin on the selling price. Australian retailers who confuse these two concepts often underprice their products. The calculator also handles multiple discount types including percentage discounts, dollar discounts, and tiered discounts (e.g., 10% off for orders over $500, 15% off for orders over $1,000). It computes the break-even discount level — the maximum discount you can offer while still covering your costs — which is essential for planning sales events.

Worked Australian Example
Practical Example
Consider Melbourne-based furniture retailer, Yarra Valley Living, which sources handcrafted timber tables from a local woodworker in Healesville, Victoria. The cost price of a solid oak dining table is $850 including delivery to the Melbourne showroom. Owner David Chen needs to set the retail selling price with a 60% markup on cost. Using the Discount & Markup Calculator, David selects Markup mode and enters the cost price of $850. He enters a 60% markup. The calculator returns a selling price of $1,360. The margin is 37.5% ($510 profit ÷ $1,360 selling price). David also checks the margin percentage to understand his gross profit on each table sold. Later, David runs a 20% off Christmas promotion. He enters the original price of $1,360 and a 20% discount. The calculator shows a discount amount of $272 and a sale price of $1,088. The effective margin at the sale price drops from 37.5% to 21.8%. David checks the break-even discount level — the calculator shows he can discount up to 37.5% before selling at cost. The 20% promotion leaves a healthy margin, and David proceeds with the campaign. He also calculates the GST component at each price point: the $1,360 selling price includes $123.64 GST, while the $1,088 sale price includes $98.91 GST.
