GST calculation

GST rate is country specific. Some countries like Australia levy a single rate on all goods and services. Others like India have different tax rates for different kinds of goods and services. This GST calculator will work for all cases.

GST = A * t / 100
GST = Tax amount
A = Gst-excluded amount
t = Gst rate in percent

Gst-inclusive amount = Gst-excluded amount + GST
