VAT calculator
Reverse VAT from a VAT-inclusive price.
Calculate the net price and VAT amount from a gross total. Use country presets or enter the exact VAT rate from your invoice.
Rates are presets for quick estimates. Local, state, province, product, and invoice rules can vary, so replace the rate when your source shows a different value.
At 20% tax, $120.00 gross equals $100.00 before tax and $20.00 tax. View calculation formula
Remove tax from a total
Net price = gross total / (1 + VAT rate / 100). The tax amount is the gross total minus the net price.
120 at 20% becomes 100 + 20
If the total is 120 and the tax rate is 20%, the pre-tax amount is 100 and the tax amount is 20.
Use the exact rate
Some countries, states, provinces, and products use reduced or combined rates. Change the rate when your invoice uses a different one.
