VAT calculator

Adding tax is not the reverse of subtracting the same percent from the gross price. If a price already includes 20 percent tax, the tax inside it is 20/120 of the total, not 20 percent of the total.

This English page starts at 20 percent only as a round example. It is not the rate of a particular country. Type the rate that applies, including a reduced rate. The Hebrew, Indonesian, and Romanian pages start from the standard rates reviewed on 12 November 2026.

Required fields are marked with *.

Use a comma or a dot for the decimal, as in 12.5 or 12,5. Type thousands as 1000 or 1 000. A single comma or dot is the decimal mark, so 1,000 means 1.

Direction

20 is only an example. Replace it with the rate you need.

How to use this calculator

  1. Choose whether the amount is before tax or already includes it.
  2. Enter the amount and edit the rate if 20 percent is not the one you need.
  3. Read the net amount, the tax, and the gross amount.

Formula

gross = net × (1 + rate / 100)

net = gross / (1 + rate / 100)

On 12 November 2026 the standard rate was 18 percent in Israel, the effective PPN on most non-luxury goods and services in Indonesia was 11 percent (statutory 12 percent times 11/12), and the standard TVA in Romania was 21 percent. Reduced rates and exemptions are not applied for you.

Worked example

1,000 before 20 percent tax

Tax is 200. The gross price is 1,200.

Removing 20 percent from 1,200 returns 1,000. Subtracting 20 percent of 1,200 would leave 960, which is the wrong net price.

Net 1,000, tax 200, gross 1,200.

Questions

Why not subtract the rate from a price that includes tax?

The rate applies to the net amount. The tax share of the gross price is rate / (100 + rate), which is smaller than the rate itself.

Can I use a reduced rate?

Yes. Replace the default. The page does not know which goods qualify for a reduced or zero rate.

Is this a tax filing tool?

No. It is arithmetic. Filing rules, exemptions, and the rate on a given date come from the tax authority.
