GST is generally calculated on the net price (the base price or exclusive of tax amount) of goods or services. The GST rate is applied to this taxable value to determine the tax amount, which is then added to the net price to arrive at the gross price (inclusive of tax) paid by the consumer.
Is the GST calculated on the base price or the total price? GST is calculated on the base price. Enter the net price before GST and then enter the GST rate. It will calculate the total cost of production, CGST, SGST, and total tax.
The tax invoice that you receive will likely show $100 (which is equal to 1/11th) as being payable by you. The amount of $1,100 is the gross expense, the $100 is GST and $1,000 is the net amount. You will claim back the $100 in your BAS and the net amount of $1,000 will show in your tax return.
GST is calculated on the transaction value of goods or services, which is the price paid for the supply, including any additional costs like packaging, delivery, and commissions.
The suppliers give numerous kinds of discounts such as cash, trade, quantity/volume/performance, etc are given by the suppliers. Such discounts are reduced from the taxable value / Supply value. Since the value of taxable supply is the transaction value, GST is leviable on the value after deducting the discounts.
This is because GST is calculated on the final price after the discount has been applied. The GST on a discounted sale must reflect the reduced price, and the tax invoice must show the discount and adjusted GST amount. Discounts offered at the time of sale are generally straightforward in terms of GST treatment.
GST included in MRP

GST is a broad-based tax of 10% on most goods, services and other items sold or consumed in Australia. To work out the cost of an item including GST, multiply the amount exclusive of GST by 1.1. To work out the GST component, divide the GST inclusive cost by 11.
The formula for calculating GST is to multiply the net price (exclusive of GST) by 1.1 or divide the price including GST by 11 to determine the GST component.
Net price = Cost of the product + GST amount
For example, if a product or service costs Rs. 100 and the GST levied on that is 18%, the GST amount will be 100 x 18% = Rs. 18. The net amount you'd have to pay would be Rs. 118.
The value of a taxable supply is the consideration payable for the supply (before GST is added). For example, if the value of the supply is $100, the GST payable is 10 percent of $100, being $10. The price GST inclusive of the supply is $110. To work out the GST paid, you can divide by 11.

Assuming $50.00 as the expense, multiply by 0.05 and divide by 1.05 to determine the GST, which is $2.38. (GST = $50/105 X . 05.) When invoicing for a service that is GST applicable, Accounting will include the GST in the total amount to be billed.
GST calculation can be explained by a simple illustration : If a goods or services is sold at Rs. 1,000 and the GST rate applicable is 18%, then the net price calculated will be = 1,000+ (1,000X(18/100)) = 1,000+180 = Rs. 1,180.
