## What is GST Calc?

GST Calc calculates the Goods and Service Tax (GST) for any item.

It will calculate the GST in two directions.
1.  Enter the GST excluded price to calculate the GST and add it to the base price.
2.  Enter the GST included price and it will subtract the GST from the value and give you the base price.

There is a 3rd field that allows you to change the GST rate.  It will default to Australia's 10% however it can be changed to match the GST/Sales Tax/VAT of other locations.
