How to Calculate

How to Calculate VAT in Thailand


Calculating VAT in Thailand involves two primary operations: adding VAT to a net amount and removing VAT from a gross amount. Here's how each calculation works:


Adding VAT (Net to Gross)


When you have a net price (excluding VAT) and need to calculate the final price including VAT:


Formula: Gross Amount = Net Amount x (1 + 7/100)

Multiplier: 1.0700


Example Calculation:

  • Net Amount: 100.00
  • VAT Rate: 7%
  • VAT Amount: 100.00 x 7/100 = 7.00
  • Gross Amount: 100.00 + 7.00 = 107.00

    • Removing VAT (Gross to Net) - Reverse Calculation


    When you have a gross price (including VAT) and need to extract the net amount and VAT:


    Formula: Net Amount = Gross Amount / (1 + 7/100)

    Divider: 1.0700


    Example Calculation:

  • Gross Amount: 107.00
  • VAT Rate: 7%
  • Net Amount: 107.00 / 1.0700 = 100.00
  • VAT Amount: 107.00 - 100.00 = 7.00
