GST in Australia

The GST is a broad-based tax of 10% on the supply of most goods, services and anything else consumed in Australia.

GST Formula

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 ($110/11=$10);
• To work out the price without GST you have to divide the amount by 1.1 ($110/1.1=$100)
