GST calculation

GST taxation 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. Select "Exclude tax" option for reverse GST calculation.

Formula:
GST = A * t / 100
where,
GST = Tax amount
A = GST-excluded amount
t = GST rate in percent

GST-inclusive amount = GST-excluded amount + GST
