    Type the price and either tap a common rate or enter your own percentage. The figures appear as soon as the amount is valid, with no button to press.

Why use this tool

Add or remove VAT in one place

Switch between putting VAT on top of a net price and stripping it out of a VAT-inclusive gross price without leaving the page.

Reverse a VAT-inclusive price

Remove mode divides a gross price back into the net price and the VAT portion, so the two always add back to the gross you entered.

Common rates or your own

One tap sets 5, 10, 15, or 20 percent, and a custom field takes any other rate, decimals included. A blank or zero rate handles zero-rated items.

Exact two-decimal figures

Every amount is rounded to two decimal places and the net and VAT always reconcile to the gross, with no lost or extra cent from rounding.

Runs entirely in your browser

Everything happens on your device as you type. Nothing is uploaded, so the prices you enter never leave the page.

About this tool

This VAT calculator works in both directions. In add mode you type a net price and a VAT rate, and it shows the VAT amount and the gross price with VAT included. In remove mode you type a gross price that already has VAT in it, and it backs the VAT out to reveal the net price and how much of the total was VAT. Everything updates the moment the price is valid, so there is no button to press.

The rate is yours to set. Tap a common preset like 5, 10, 15, or 20 percent, or type any rate you need, decimals such as 7.5 or 12.5 included, and set it to zero for zero-rated goods. All the money maths runs to two decimal places, and the net, VAT, and gross always add back together exactly, so a rounding difference never leaves a stray cent. The figures are plain numbers with no currency symbol, so the result reads the same in pounds, euros, dollars, or any other currency.

Use add mode to quote a price with VAT for an invoice or a shelf label, and remove mode to split a VAT-inclusive total into the net price and the VAT for a receipt, an expense claim, or a return. Nothing you enter is uploaded or stored. For general tax on a price the sales tax calculator covers the same idea, and to take money off a price rather than add it on, try the discount calculator.

Frequently asked questions

What is the difference between add and remove VAT?
Add VAT starts from a net price and puts the VAT on top to give the gross price. Remove VAT starts from a gross price that already includes VAT and works backwards to the net price and the VAT portion.
How does removing VAT from a gross price work?
The VAT-inclusive gross price is divided by one plus the rate. For example, a 120.00 gross at 20 percent gives 100.00 net and 20.00 of VAT. The two figures always add back to the gross you entered.
Can I use a rate of zero?
Yes. Leave the rate blank or set it to 0 and the VAT is zero, so the gross equals the net and remove mode returns the price unchanged. This matches zero-rated goods. Any positive rate, with decimals, works too.
Which currency does it use?
None in particular. The calculator works with plain numbers to two decimal places, so the result reads the same whether you are working in pounds, euros, dollars, or any other currency.
Is my data uploaded anywhere?
No. Everything runs in your browser; nothing is sent to a server. The prices and rate you type are never uploaded, stored, or logged.
