Profit margin & markup calculator

See gross profit, profit margin and markup from your cost and selling price. Keep your Australian GST calculation separate.

Use the same tax basis for both values. Gross profit excludes overheads, fees and income tax.

Gross profit
$20.00
Profit margin
20.00%
Markup on cost
25.00%
Selling price + 10% GST
$110.00

Margin and markup use different starting points.

Margin divides gross profit by selling price. Markup divides gross profit by cost. A product costing $80 and selling for $100 has $20 gross profit, a 20% margin and a 25% markup.

Use consistent tax treatment for both prices. The final GST-inclusive figure assumes a fully taxable sale at 10%. Read the margin and markup guide for target-pricing examples.
