GST Calculation Formula
There are two ways to calculate GST, depending on whether the price already includes GST or not.
➕ Add GST formula
Use this formula when the given price does not include GST and you want to add it.
Formulas:
- GST amount = Price × 0.10
- Total Price Including GST = Price × 1.10
Example:
If the original price is $324:
- GST = $324 × 0.10 = AUD 32.40
- Total = $324 × 1.10 = AUD 356.40
➖ Remove GST formula
Use this formula when the price already includes GST, and you want to find the original value.
Formulas:
- GST = Total Price ÷ 11
- Price (Excluding GST) = Total Price ÷ 1.10
Example:
If the total price is $356.40:
- GST = $356.40 ÷ 11 = $32.40
- Original Price = $356.40 ÷ 1.10 = $324
Quick Formula Summary
- Add GST → Multiply by 1.10
- Remove GST → Divide by 1.10
- Find GST from total → Divide by 11

GST-Free Food
Most everyday food items are GST-free, but some food items are taxable. For example, fresh and basic food is usually GST-free, while some processed or ready-to-eat food is taxable. It depends on how a product is sold (dine-in food or hot takeaway is taxable). So it’s always good to double-check before calculating.

GST on Imported Goods
GST on imported goods in Australia depends on the value of the goods and how they are used. Remember, GST is calculated on the total value, which includes the cost of the item, customs duty, shipping, and insurance.
👤 For Individuals
If you are buying goods for personal use and the value is low (generally under AUD 1,000) and it is a custom-free product, GST will not be applied. But it will be applied if the product is non-custom or its price is more than 1000$.
🏢 For Businesses
If you are importing goods for business, GST will be charged. The tax will be calculated on the total landed cost (product price + duty + delivery + insurance).
For Example
If you import goods worth AUD 40,000 and additional costs (duty, shipping, insurance) increase the total value to 44,300, GST is applied on that final amount 44,300, not just the product price.
But if your business is GST-registered, you can claim GST credits, which reduce your overall tax burden. How to claim GST credits ↗
