GST Calculator

Omni's GST calculator helps you to find out either the net or gross price of your product based on a percentage-based GST (Goods and Services Tax) rate. It's straightforward 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), and our article covers subjects such as the GST definition and why our tool can be used as Australian GST calculator.

Since GST is essentially the same thing as value-added tax, you can use our popular margin and VAT calculator, which lets you combine a price hike due to your gross margin and the tax on goods and services. If you live in the United States, you might be more interested in sales tax, which is another form of consumption tax. Keep reading to find out:

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. Where applicable, governments impose it on goods and services on every level of the distribution chain.

For instance, when a factory sells a product to a wholesaler, it includes GST in the price. Then, when the wholesaler sells the product to a retailer, GST is added again. However, the wholesaler can claim a refund for the GST paid to the factory. In essence, the GST charged at this stage is only on the value added—the difference between what the wholesaler pays the manufacturer and the selling price to the retailer. The same rule applies to every next transaction with one exemption - the final consumers cannot get the tax refund since they are the last in this chain. It boils down to two things:

  • The amount the government collects equals 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

To estimate 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 the GST rate. $40 × 0.1 = €4.
  4. To determine the gross price, add the tax amount to the GST exclusive price: €40 + €4 = €44

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

How to use the GST calculator

Our calculator is as straightforward as possible! Here are the variables used in the calculator. Fill out any two that you know to calculate the missing ones automatically.

  1. Net price - Enter the price before GST is added.
  2. GST - Input your GST rate.
  3. Gross price - This is the final price including GST.
  4. Tax amount - This shows how much GST is added to the net price (same as GST but in a specific amount instead of a percentage).

Australian GST calculator

The core rules in Australia are the same as everywhere else where VAT is in use. As is the case in many other countries, Australia exempts certain essential goods from taxation. Also, businesses with an annual turnover below $75,000 do not have to register for GST and don't have to collect it on goods or services.

If your business is GST-registered and purchases goods or services for consumption or resale to an end customer, it can get a refund on the tax paid on those purchases. Therefore, effectively, there is no GST payable on those supplies for your enterprise.

FAQs

How do I calculate GST percentage?

To calculate the GST percentage:

  1. Note down the price paid by the end consumer and identify the net price (the price before GST).
  2. Divide the gross price (the price including GST) by the net price, subtract one, and then multiply by 100%. This will give you the GST rate as a percentage.

You can check your calculation using Omni's GST Calculator tool.

What does GST mean?

The GST definition is Goods and Service Tax. It is an amount that consumers pay when buying a product or service. The government collects it from business owners. That's the reason why businesses add it to the net price of their products.

How does GST work?

GST or Goods and Services Tax is a value-added to the "net price" when sold to the consumer. Net price is GST exclusive, whereas what the consumer pays is GST inclusive.

Governments define the percentage and request that business owners add it to the net price. Then, the government collects that money from them.

How do I add GST to a price?

To add GST to a price:

  1. Once you have the GST from a government website or previously calculated in the Indian /Australian GST calculator, verify that you have the net price, which is also called the GST exclusive price.
  2. Express the percentage as a decimal value. For example, if the GST is 10%, write it down as 0.10. If GST is 15%, then you have 0.15.
  3. Add 1 to the GST decimal value. Multiply the result by the net price. Congratulations, you have your GST-inclusive price.
