How to Calculate the GST From Gross
- 1). Determine the gross sales price of the product or service you are buying. For instance, suppose you wanted to buy an article of clothing for 10$.
- 2). Multiply that gross amount by 0.05. So 10 times 0.05 equals 50 cents.
- 3). Add that amount onto the bill to get the total amount, including GST. The total is 10.50$, including the GST.
