The VAT Calculator allows users to calculate one of the following: VAT amount, Price before VAT, Price after VAT, or VAT rate. The system uses basic arithmetic to reverse-engineer any missing value based on the three provided.
- VAT Amount = (VAT Rate / 100) × Price Before VAT
- Price After VAT = Price Before VAT + VAT Amount
- VAT Rate = (VAT Amount / Price Before VAT) × 100
- Price Before VAT = Price After VAT - VAT Amount
The component intelligently determines which one of the four values is left blank and calculates it. It is extremely useful for small business owners and consumers wanting to check tax components.
