روش استفاده از Reverse VAT Calculator — remove VAT from a VAT-inclusive price
Find the net amount and VAT element when the starting price already includes VAT at a known rate.
Net = gross ÷ (1 + VAT rate ÷ 100). VAT amount = gross − net. Subtracting the VAT percentage directly gives the wrong answer.
Find the net amount and VAT element when the starting price already includes VAT at a known rate. The linked Sellible tool keeps the fields, units and output together so the assumptions can be reviewed before the result is used.

Example values and result
These values demonstrate the method; replace them with measurements, rates or file details that match the real task.
- VAT-inclusive total
- £120.00
- VAT rate
- 20%
- Net amount
- £100.00
- VAT element
- £20.00
Twenty percent VAT added to £100 gives £120. Removing VAT therefore divides by 1.20 rather than subtracting 20% from £120.
