What is GST?

Answer 2

I presume this is a tax, probably Goods and Services Tax in Canada. Your post isn't clear. If you have 100 to spend on an item it will cost you 100 + 10% of 100. Or you may mean that the total cost of an item, including GST, is 100.00. And you want to know the cost without GST?

Answer 3

Goods and Services Tax (applies to all Canada). Some provinces combine with the provincial sales tax to call it Harmonized Sales Tax (HST).

Assume $100 includes GST, then the GST portion is $100*(10/110)=$100/11.

If the GST rate is 15%, then the GST portion will be $100*(15/115).
