Questions people ask
+How do you reverse-calculate sales tax?
Divide the total by 1 plus the tax rate. With 13% HST, divide by 1.13: $113 including tax is $100 before tax and $13 of HST.
+Why not just take 13% off the total?
Because the tax was 13% of the smaller pre-tax price, not of the total. Taking 13% off $113 gives $98.31, which is $1.69 too low.
