Quick Answer & Understanding Your Result
Value Added Tax (VAT) is calculated by multiplying the net price by the tax rate to add tax ( Gross = Net × (1 + Rate)) or dividing the gross total by (1 + Rate) to remove tax ( Net = Gross / (1 + Rate)).
Standard Global VAT / GST Tax Rates
- Vietnam: Standard 10% (Reduced 8% incentive rate for eligible goods).
- United Kingdom & France: Standard 20% (Reduced 5% / 5.5% on essentials).
- Germany: Standard 19% (Reduced 7% on food and books).
- Australia & Singapore: GST 10% / 9% flat rate.
Core Mathematical Components
- Tax Amount (Add VAT): VAT = Net Price × Tax Rate.
- Net Amount (Remove VAT): Net Price = Gross Total / (1 + Tax Rate).
- Tax Included: VAT Amount = Gross Total - Net Price.
