## What is Australia GST?

Aussie GST is a simple GST calculator for the Australian Goods and Services Tax. 

The fastest and most straight forward GST app on the App Store. Simply enter your value in one of three boxes, and the other values are calculated as you key in the numbers. 

Aussie GST is useful in three specific cases: 
- 'Removing GST': When you have a price which already includes GST, and you need to know the GST component of that value, and the amount left after GST is excluded. 
- 'Adding GST': When you know a price excluding GST, and you need to know how much GST will be added, and what the final value is including GST. 
- 'Working backwards': When you only know the GST amount, and you need to know what the original price of the goods were, excluding and including GST. 

Why Aussie GST is great:

COPY AND PASTE
Starting values can be paste into any field, and results can be copied and pasted into other apps.

QUICK ENTRY
The large number-pad is quick and easy.

AUTOMATIC CALCULATIONS
Results are calculated and displayed as you key in the numbers.

QUICK RESET
Tap the clear button in any of the boxes to reset the calculation.

MULTI-PURPOSE
Enter a value in any of the three input fields, and the other two fields will be calculated from that. 

GREAT FOR TRAVELLERS
Calculate the GST you can claim back at the airport when leaving Australia (Tourist Refund Scheme).

UNIVERSAL APP
Aussie GST is a Universal app, meaning you only buy it once and can install it for free on your iPhone, iPod Touch, and iPad.
