FAQ
What is a VAT generator?
It calculates the VAT amount and the net/gross totals from an amount and a VAT rate.
How do I add VAT to a net price?
Select Add VAT (Net → Gross), enter the net amount and rate, and the tool outputs VAT and gross.
How do I remove VAT from a VAT-inclusive total?
Select Remove VAT (Gross → Net) and enter the gross total; the tool extracts the net and VAT portion.
What formula does this tool use?
Add mode: VAT = Net × (rate/100), Gross = Net + VAT. Remove mode: Net = Gross ÷ (1 + rate/100), VAT = Gross − Net.
Why doesn’t the VAT amount match my receipt exactly?
Some invoices round per line item rather than on the final total; try changing the decimals or matching the invoice’s rounding method.
Does this tool store my data?
No—calculations run locally in your browser and nothing is sent over the network.
Can I use this for any country’s VAT/GST rate?
Yes, enter any percentage rate; just make sure it matches the rules you need for your jurisdiction.
