Margin vs markup

Margin is profit as a percentage of the selling price (profit ÷ price). Markup is profit as a percentage of cost (profit ÷ cost). A 25% markup equals only a 20% margin — mixing them up is one of the most common pricing mistakes in small business.

Price with tax in mind

After finding your selling price, add tax with the GST / VAT Calculator and bill clients with the Invoice Generator.
