The GST is a broad-based tax of 10% on the supply of most goods, services and anything else consumed in Australia.
How to calculate GST in Australia?
When adding 10% to the price is relatively easy (just multiply the amount by 1.1), reverse GST calculations are quite tricky:
- To figure out how much GST was included in the price you have to divide the price by 11 ($220/11=$20);
- To work out the price without GST you have to divide the amount by 1.1 ($220/1.1=$200)
GST Calculations Mistake
Avoid most common GST calculation mistake when using percentages:
$200 + 10% = $220, however $220 - 10% is NOT equal $200, actually it's $198!
Sometimes numbers are not so pretty, so why do all this manual work when you can enter the amount into this GST Calculator and get all the calculations at once! Enjoy!

GST Calculator Update
Taking into consideration your feedback we updated our GST Calculator and now when you enter the number into "Amount" field you can see both outputs on the same page:
- the amount of GST to add to the price and GST inclusive price, AND
- how much GST is included in the price and GST exclusive price.
There is also an option to change GST percentage if Australia will change GST in the future or if you want to calculate GST for other countries. For example, New Zealand GST (15%) or Singapore GST (7%).
