About this tool

Need to add 20% VAT to a price, or take VAT off an invoice total? Pick the country, the rate fills in by itself (UK 20%, Ireland 23%, Australia 10% GST, India 18% GST…), type the amount and get the net, the tax and the gross with the formula. Every rate can be edited.

When to use it

Quotes and invoices

Start from the net price and get the tax and the gross total for your invoice.

Reverse VAT on a receipt

A receipt only shows the total: work out the net price and the reclaimable VAT.

US sales tax

Type your state and city rate to see the price at the till.

How to use

  1. Pick the country: its standard rate fills in.
  2. Click a reduced rate if needed, or type your own.
  3. Choose whether your amount is before or including tax, then type it.
  4. Read the net, the tax and the gross, and copy the result.

How it works

Gross = net × (1 + rate ÷ 100). Net = gross ÷ (1 + rate ÷ 100). The tax is the difference.

To remove 20% VAT you divide by 1.2, you do not take off 20%: £120 including VAT is £100 before VAT, not £96.

Tips for best results

  • In the UK, the reduced 5% rate covers home energy and the 0% rate most food and children's clothes.
  • Round the tax to the penny on each invoice line, then add them up.
  • US sales tax is added at the till, so shelf prices never include it.
  • Rates sometimes change: check them on the official site linked below the tool.

Common problems and fixes

I took 20% off and the net price is wrong

Divide by 1.2 instead. Choose “Including tax” as the amount you know and the tool does it right.

My rate is not listed

Type it in the rate field, or choose “Other country”.

The total is off by a cent

The tax is rounded to the nearest cent; on a multi-line invoice the sum of roundings can differ by a cent.
