Gross vs Net Price After Tax

Net usually means before tax; gross includes tax — or the opposite in payroll! In retail, clarify whether a shelf tag is VAT-inclusive.

Extract vs add

To add tax: multiply net by (1 + rate). To extract tax from a gross total: divide by (1 + rate).

Use GST / VAT for both directions and the Discount Calculator when promotions apply before tax (jurisdiction-dependent).
