Frequently Asked Questions

What is the difference between margin and markup?

Margin is the profit as a percentage of the selling price. Markup is the profit as a percentage of the cost price. A 50% markup equals a 33.3% margin.

How do I calculate GST on a price?

Use the GST calculator. Enter the base price and GST rate. For 'Add GST', it adds the tax to get the final price. For 'Remove GST', it extracts the base price from a GST-inclusive amount.

What is a percentage increase vs markup?

Percentage increase compares any two values (like old vs new salary). Markup specifically calculates a selling price by adding a percentage to the cost price.

How is profit percentage calculated?

Profit % = ((Selling Price - Cost Price) ÷ Cost Price) × 100. Enter cost price as A and selling price as B in the Profit calculator.

What is profit margin?

Profit margin = ((Selling Price - Cost Price) ÷ Selling Price) × 100. It tells you what percentage of the selling price is profit.
