Formula Explained

The calculation to find the price without GST uses this simple formula:

Original Price = (Price with GST) / (1 + GST Rate)

For example, if an item costs $110 including 10% GST:

Original Price = $110 / (1 + 0.10) = $110 / 1.10 ≈ $100

The calculator uses this formula to reverse the GST calculation and provide you with the original price before tax was added.

The original price before GST was $110.

Example 2: 15% GST

For a service priced at $115 including 15% GST:
