How VAT Calculation Works

VAT (Value Added Tax) is calculated as a percentage of the base amount. The standard formula depends on whether you are adding VAT to a base amount or extracting it from a total sum.

Key Formulas

• Adding VAT: Total = Base Amount × (1 + VAT Rate / 100)
• Extracting VAT: Base Amount = Total Amount / (1 + VAT Rate / 100)
• VAT Amount: Total - Base Amount

ℹ️ VAT rates vary by country and product type. Always verify the correct rate for your jurisdiction before finalizing calculations.
