What percent?

[playfelt]

When you look at the T2125 or whatever the number is - forget you just fill out the info on the lines and do the math. Yes you take all of your household expenses like mortgage interest (not the actual mortgage paid just the interest paid), utilities, house insurance (not your daycare ryder part) and those are added together. Then you use the amount of space used out of the total (120 out of 250 in the example below) and then you also have to further reduce that by the hours used so if you work 5 out of 7 days a week and 12 hours out of 24 hours a day you have to add those math equations in there too to get the amount you can can claim for business use of the home.

ex. 120 divided by 250 X 5 divided by 7 x 12 divided by 24 = amount you can claim
