Formula & Theory — VAT Calculator
Value-Added Tax is a consumption tax applied at each stage of production. The VAT Calculator inverts the gross/net relationship using the rate r so you can move between any two of the three values cleanly.
Gross = Net × (1 + r)
Net = Gross / (1 + r)
VAT = Net × r| Symbol | Meaning |
|---|---|
| Net | Price before VAT |
| Gross | Price including VAT |
| r | VAT rate (as decimal) |
| VAT | Tax portion of the price |
