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
