- Markup is calculated as a percentage of cost.
- Margin is calculated as a percentage of selling price.
- Only one input mode is used to derive the selling price at a time.
- Figures exclude GST unless you enter GST-inclusive costs yourself.
How this calculator works
Three modes cover every pricing question: price from a markup percentage, price from a desired margin percentage, or the markup and margin implied by a cost and selling price you already have.
Frequently asked questions
Why can't I use a 100% margin?
A 100% margin would mean zero cost. Margins must stay below 100%, though markups can exceed it.
How do I convert markup to margin?
Margin equals markup divided by (1 + markup). A 50% markup is a 33.33% margin.
Should I add GST after markup?
Yes. Price on GST-exclusive costs, then add 10% GST to the final retail price if registered.
