Understanding GST Calculations
Exclusive to Inclusive
When you have a base amount and need to add GST to calculate the total inclusive amount:
Formula
Inclusive Amount = Base Amount + (Base Amount × GST Rate / 100)
GST Amount = Base Amount × GST Rate / 100
Inclusive to Exclusive
When you have an amount that already includes GST and need to find the base amount and GST component:
Formula
Base Amount = Inclusive Amount / (1 + GST Rate / 100)
GST Amount = Inclusive Amount – Base Amount
