This reverse VAT calculator helps you work backwards from a tax-inclusive amount to find the amount excluding VAT and the VAT amount itself. It is useful for invoices, accounting, ecommerce and purchase analysis.
It is useful when you only know the tax-inclusive total and need to know the tax portion and the base amount excluding VAT.
Formula: Amount excl. VAT = Total incl. VAT / (1 + VAT Rate) | VAT = Total incl. VAT − Amount excl. VAT
Example: 1,200 including 20% VAT gives 1,000 excl. VAT and 200 VAT.
