This page opens the VAT calculator with Australia chosen as the country. The rate box shows 10%, and 10% is the only quick pick. The net price, the GST and the total update as you type.
To find the GST inside a price that already includes it, divide the price by 11. A total of $110 contains $10 of GST on a $100 net price. Rates can change, so confirm the current rate with the tax authority before you use a figure on an invoice.
How to add or remove VAT
- Type the amount, then choose your country for its rate, or type the rate or tap a quick pick.
- Choose Add tax for a net price, or Remove tax for a gross price.
- Read the net, tax and gross figures. The main answer is highlighted.
Questions
What is the quick way to add GST in my head?
Add a tenth: $80 plus $8 is $88. To go back from $88, divide by 11, which gives the $8 of GST.
Why does dividing a GST-inclusive price by 10 give the wrong GST?
The total already contains the tax, so a tenth of it is too much. A tenth of $110 is $11, but the GST in it is $10.
What is the difference between net and gross?
Net is the price before tax. Gross is the price with the tax added on. Gross is always net plus the tax amount.
How do I add VAT to a price?
Multiply the net price by the rate written as a decimal, then add the result. At 20%, 100 × 1.2 = 120, so the tax is 20 and the gross price is 120.
How do I take VAT out of a price?
Divide the gross price by 1 plus the rate written as a decimal. Removing 20% from 120 gives 120 ÷ 1.2 = 100 net, and the tax is the difference, 20.
Is GST or sales tax worked out the same way?
The arithmetic is the same for any percentage tax added on top of a price. Which tax applies, which rate is right and how it is shown on an invoice depend on where you are, so check the official rules for your case.
