GST Calculator

GST calculator figures out a price of product including Goods and Service Tax.

GST calculator helps you find out either net or gross price of your product based on a percentage-based GST tax rate. It's very simple to use - provide values that you know (for example net price and GST rate) to receive other values (in this case gross price and tax amount). Since GST is essentially the same thing as value-added tax, you're free to use our popular margin and VAT, which lets you combine a price hike due to your gross margin and the tax on goods and services.

What is GST - GST definition

Goods and Services Tax is the same thing as VAT (value-added tax), so the GST definition is... well, the same. It is imposed on goods and services on every level of the distribution chain. For example, factory adds it when it sells it to a wholesaler. Wholesaler adds it when it sells it to a retailer, but it can get the original amount returned. So in effect, the tax added on this level is applied only to the difference in net price between the manufacturer and the wholesaler. The same rule applies with every next transaction with one exemption - the final consumer cannot get the tax refund. Only businesses can have the tax returned. It boils down to two things:

  • the amount the government collects equals to the amount paid on the last transaction.
  • the government is sure to collect the tax, since it's collected when every consecutive transaction happens.

How to calculate GST

  1. Determine the net price (the price without the GST). Let's make it €40.
  2. Find out the GST rate. It will be 10% in our example. If expressed in percentages, divide it by 100. So it's 10 / 100 = 0.1.
  3. To calculate the tax amount: multiply the net price by GST rate. $40 * 0.1 = €4.
  4. To determine the gross price: multiply the net price by GST (again, we'd get €4) rate and then:
  5. Add it to the VAT exclusive price. €40 + €4 = €44.

This is simply a case of an percentage increase calculation and this is what you'd do in any net to gross situation.

Australian GST calculator

The core rules in Australia are the same as everywhere else where VAT is used. As is the case in many other countries, Australia exempts certain essential goods from being subjected to the tax. Also, businesses with annual turnover below $75000 do not have to register for GST and don't have to collect it on goods or services. It's not always beneficial - if your business is not GST-registered, it cannot get a refund on the tax paid on its own purchases.
