How to Calculate GST in Ontario

Calculating GST in Ontario is straightforward. You need to know the price of the item and the applicable GST rate. Here's how to do it:

Determine the price of the item before tax.
Multiply the price by the GST rate (5% for most items).
Add the GST amount to the original price to get the total cost.

Example: If you buy a $100 item in Ontario, the GST amount is $5 (100 × 0.05). The total cost is $105.
