⚙️Technical & Educational Details
Calculations adhere to standard international tax accounting formulas to avoid common mathematical errors, such as simply subtracting the tax percentage from a gross figure.
• Adding VAT: Gross = Net × (1 + Rate ÷ 100) | VAT Amount = Gross − Net
• Extracting VAT: Net = Gross ÷ (1 + Rate ÷ 100) | VAT Amount = Gross − Net
• Example: At 21%, a €121 gross total yields exactly €100 net and €21 VAT.
