What is the VAT Calculator?

It is a tool that adds Value Added Tax to a net price or removes VAT already included in a gross price, showing the net, VAT amount and gross total for either direction.

How does the VAT Calculator add VAT to a price?

In Add VAT mode, enter the net price and rate. The tool multiplies the net price by (1 + rate ÷ 100) to get the gross price, and the difference is the VAT amount.

How does the reverse VAT calculator remove VAT from a gross price?

In Remove VAT mode, enter the gross (VAT-inclusive) price and rate. The tool divides the gross price by (1 + rate ÷ 100) to find the net price, then subtracts to get the VAT amount.

Can I use the VAT Calculator for UK, EU or other country rates?

Yes. The VAT rate field accepts any percentage, so you can enter the UK standard rate, a reduced rate, an EU member state's rate, or any other country's VAT or GST rate.

Does the VAT Calculator upload my prices anywhere?

No. The VAT Calculator runs entirely in your browser. The amounts and rates you type never leave your device and are not uploaded to ArrayKit.

Is the VAT Calculator result financial or tax advice?

No. It gives estimates only, based on the amount and rate you enter. Always confirm the correct VAT rate and treatment with a tax professional or your local tax authority.

About VAT Calculator

VAT Calculator adds Value Added Tax on top of a net price or backs it out of a VAT-inclusive gross price, so you always know the net, VAT and gross figures for an invoice or quote. Switch between Add VAT and Remove VAT with a single toggle, type an amount and a VAT rate, and the net price, VAT amount and gross total update as you type. It is useful for freelancers pricing a quote, shop owners checking a receipt, or anyone confirming how much VAT is included in a gross price. These are estimates only, not tax or financial advice — confirm the applicable rate with a tax professional or your local tax authority. Everything computes locally in your browser; nothing you type is uploaded.

Common errors & troubleshooting

VAT amount looks too high or too low. — Check whether the amount you entered is the net (VAT-exclusive) price or the gross (VAT-inclusive) price, and pick the matching Add VAT or Remove VAT mode.
Rate entered as 0.2 instead of 20. — Enter the VAT rate as a whole percentage, e.g. 20 for 20%, not as a decimal fraction like 0.2.
Removed VAT doesn't match the amount printed on a receipt. — Some receipts round each line item before totaling, which can shift the VAT figure by a cent or two versus a single reverse calculation on the total.
Result shows an error banner. — Make sure both the amount and the VAT rate are filled in and are 0 or greater — negative values aren't valid VAT inputs.
