About VAT
Adding vs removing tax
Adding tax goes from a net (pre-tax) price to gross. Removing tax goes from a gross (tax-inclusive) price back to net — useful when a receipt only shows the total.
The math
Add: gross = net x (1 + rate). Remove: net = gross / (1 + rate). The tax is the difference.
Where it helps
Invoicing, expense claims and bookkeeping where you need to separate the tax portion of a price.
Frequently asked questions
How do I remove VAT from a price?
Divide the gross price by (1 + rate). This tool does it in Remove mode.
What rate should I use?
Use your local VAT or sales tax rate — the field accepts any percentage.
Is VAT the same as sales tax?
They work differently behind the scenes, but the arithmetic of adding/removing a percentage is the same.
