Calculators
VAT Calculator
VAT Calculator is part of Toolspire and is ready as soon as this page loads. One rate, two readings. Use the gross when the price is before VAT. Use the hidden-VAT figure when the shelf price already includes it. This is not a GST return.

What you can do here
Exclusive price becomes the headline
The large number is what a customer pays if VAT is added on top.
Inclusive price stays in the detail
The second VAT figure is the tax already inside the amount you typed.
A single rate
There is no place-of-supply split. Type the VAT percentage on the invoice.

How to use the VAT Calculator
- 1
Decide which price you were given
If the quote says “plus VAT”, the headline gross is the one you want. If it says “including VAT”, use the inside figure.
- 2
Type the rate on the invoice
20 is a common UK example. A 5% reduced rate is just as valid. Do not leave 20 if your invoice says otherwise.
- 3
Do not use this for an Indian GST invoice
Open the GST calculator when you need CGST and SGST. This page will not split them.
Worth knowing
- VAT Calculator on Toolspire: on an exclusive price, VAT is amount × rate ÷ 100, and the headline is the price plus that VAT.
- On an inclusive price, VAT is amount × rate ÷ (100 + rate). At 20%, that is one sixth of the shelf price, not 20% of it.
- The detail prints both readings so you do not have to guess which way the invoice was written.
- This page is not the Indian GST calculator. GST has CGST, SGST and IGST splits; VAT here is a single rate.
What the number is actually counting
Adding VAT multiplies the net by the rate. Removing VAT divides by (1 + rate) and subtracts. People mix those up because 20% added is not 20% of the gross: on a £120 inclusive price the VAT is £20, which is 20 ÷ 120 of the gross. The detail shows that second figure next to the add-on figure.
