Standard Forward VAT (Net to Gross) Formulas & Global Tax Rates
When adding VAT to a pre-tax Net price, the tax amount and final Gross invoice total are computed using standard forward tax equations.
VAT Amount = Net Price × (VAT Rate % ÷ 100)For a $1,000 Net invoice at 10% VAT, the VAT Amount is $1,000 × 0.10 = $100.
Gross Total = Net Price × (1 + VAT Rate % ÷ 100)For a $1,000 Net invoice at 10% VAT, the Gross Total payable by the buyer is $1,000 × 1.10 = $1,100.

Frequently Asked Questions about VAT & Sales Tax Calculator (Add Tax: Net → Gross)
How do I calculate VAT when I have the Net price before tax?
Multiply the Net price by the VAT percentage divided by 100 to get the VAT amount, then add it to the Net price. For example, 10,000,000 VND Net at 8% VAT produces 800,000 VND in tax and a Gross total of 10,800,000 VND.
What is the difference between 8% and 10% VAT in Vietnam?
Vietnam's standard Value Added Tax (Thuế GTGT) rate is 10%. Under government economic stimulus decrees, a reduced 8% VAT rate applies to most goods and services (excluding telecommunications, finance, banking, securities, insurance, real estate, metals, and excise-taxed goods).
