How It Works
Pre-tax → Total: Total = Pre-tax × (1 + VAT rate / 100). The VAT amount = Pre-tax × VAT rate / 100.
Total → Pre-tax: Pre-tax = Total / (1 + VAT rate / 100). The VAT amount = Total − Pre-tax.
The highlighted box shows the calculated value (the one you did not enter). All three values — pre-tax, VAT amount, and total — are displayed simultaneously for easy reference.
