GST Inclusive Calculation Formula
Understanding the mathematical formula behind GST inclusive price calculations
Calculate Base Price
This formula extracts the original price from a GST-inclusive amount by dividing by (1 + tax rate).
Base Price = Inclusive Price ÷ (1 + GST Rate) Example: If inclusive price is $115 with 15% GST: $115 ÷ 1.15 = $100 base price
Calculate GST Component
Once you have the base price, subtract it from the inclusive price to get the GST amount.
GST Amount = Inclusive Price - Base Price Example: GST Component: $115 - $100 = $15
