How It Works & Methodology

Sales Tax and Value Added Tax (VAT) are consumption taxes levied on the purchase of goods and services. This calculator supports two operational directions:

  • Add Tax (Net → Gross): Calculates the additional tax and total checkout price from a pre-tax amount.
    Tax = Net Price × (Rate / 100)
    Gross Price = Net Price + Tax
  • Extract Included Tax (Reverse VAT / Gross → Net): Back-calculates the net price and embedded tax portion from a tax-inclusive retail price.
    Net Price = Gross Price / (1 + Rate / 100)
    Tax = Gross Price − Net Price

VAT vs Sales Tax vs GST

Value-Added Tax (VAT): Used across the European Union, UK, and over 160 countries. VAT is an indirect tax collected incrementally at each stage of production and distribution based on the value added at each step.

Sales Tax: Commonly used in the United States. It is a single-stage tax assessed only at the final point of retail sale to the consumer. State, county, and municipal jurisdictions often combine local rates.

Goods and Services Tax (GST): Used in countries like Canada, Australia, New Zealand, and Singapore, functioning similarly to a multi-stage VAT.
