GST / VAT Calculator
Add or remove tax from any amount with preset rates
GST and VAT are consumption taxes added to the price of goods and services in many countries. This calculator lets you either add tax to a base price (to find the final price a customer pays) or remove tax from a final price (to find the original pre-tax amount) - both common needs for invoicing and budgeting.
