Turkish VAT (KDV) Calculator

Quickly add or extract Turkish VAT at 1%, 10% or 20%.

How it is calculated

There are two modes. To add VAT to a price excluding tax: tax = net × rate/100 and gross = net + tax. To extract VAT from a price that already includes it: net = gross / (1 + rate/100) and tax = gross - net. The rate is a percentage you enter, so you can use any KDV rate, such as 1%, 10% or 20%; which one applies depends on the product or service, so check the rate for your item. The amount and rate must not be negative. Results are shown in Turkish lira to two decimals. Other countries use different VAT rates and rules.

Worked example

A product costs 1,000 before tax and the rate is 20%, in add mode. Tax = 1,000 × 0.20 = 200.00 ₺. Gross = 1,000 + 200 = 1,200.00 ₺. The net amount shown is 1,000.00 ₺. In extract mode, entering 1,200 at 20% reverses this: 1,200 / 1.20 = 1,000.00 ₺ net, with 200.00 ₺ of tax.

Common mistakes

  • Extracting VAT by taking 20% of the gross price. That gives 240, but the real tax is 200 because the rate applies to the net price; use extract mode.
  • Choosing add mode for a price that already includes KDV, which charges tax twice.
  • Applying one rate to a whole invoice when its lines carry different KDV rates.
  • Entering the rate as 0.20 instead of 20; it would be read as 0.2%.

About this calculator

This calculator adds or removes Turkey's value-added tax, known locally as KDV, from a price, letting you move between a tax-exclusive base price and the tax-inclusive amount a customer actually pays. Because different categories of goods and services can carry different KDV rates, the tool is built so the rate itself is an input you set rather than a fixed assumption.

Small business owners and freelancers in Turkey use it to quote prices correctly on invoices, while shoppers use it to check whether a listed price already includes KDV or not. It is also handy for anyone reverse-engineering a receipt to see how much of the total was tax versus the underlying price of the item.
