The Forward & Reverse Tax Formulas

Gross Price=Net Price×(1+t)Net Price=Gross Price1+t\text{Gross Price} = \text{Net Price} \times (1 + t) \quad \Longleftrightarrow \quad \text{Net Price} = \frac{\text{Gross Price}}{1 + t}

To add 20% VAT to a $100 net price: Gross = $100 × 1.20 = $120. To remove 20% VAT from a $120 gross price: Net = $120 / 1.20 = $100 (Tax = $20).
