Australia GST Calculator (10%) — free online
Working out the 10% GST on an Australian price can be fiddly. You've got a figure in front of you and you're not sure if it already includes tax or not, and the maths is easy to get slightly wrong. We added a free tool that does it for you — Australia GST Calculator (10%) — right in your browser.
What it does
It adds or removes Australia's 10% GST on any amount in AUD. Type in a number, choose whether you want to add the tax on top or pull it back out of a tax-inclusive price, and it shows you the result. That's all it does, and it does it cleanly.
Nothing leaves your device
The whole thing runs inside your browser. Nothing you type is uploaded, nothing is saved on a server, and no account is needed. When you close the tab, it's gone.
How to use it
- Open Australia GST Calculator (10%) and enter your amount in AUD.
- Choose add 10% GST or remove 10% GST.
- Read off the result and copy the number you need.
It's free with no limit. There are more small tools on the Apps page.
