How to Calculate GST in Australia

Australia's GST rate is fixed at 10% — here are the exact formulas used by our calculator.

➕

Adding GST to a Price

Multiply the GST-exclusive amount by 1.1 to get the GST-inclusive price.

Price × 1.1 = GST-Inclusive Total
e.g. $100 × 1.1 = $110
➖

Removing GST from a Price

Divide the GST-inclusive amount by 1.1 to get the original price before GST.

Price ÷ 1.1 = GST-Exclusive Amount
e.g. $110 ÷ 1.1 = $100
🔄

Finding the GST Amount

Divide a GST-inclusive price by 11 to extract exactly how much GST was charged.

Price ÷ 11 = GST Component
e.g. $110 ÷ 11 = $10 GST
