# How is the Canada Employment Amount tax credit calculated?

To calculate the Canada Employment Amount as a non refundable tax credit, this link explains:

Canada employment amount is a non-refundable credit for work-related expenses, such as home computers, uniforms, and supplies. It was introduced in 2006.

I was thinking that the amount that I can claim as a non refundable credit is the total cost of these expenses. But, it says:

It is calculated by multiplying the lowest federal tax rate by the amount.

How can the expenses be approximated by the above calculation?

According to the examples listed on the page you linked (look immediately below the passage you quoted), you first look up the maximum employment amount by year. For 2012, it was $1,095. Then, if your income falls below the maximum, you multiply the lowest tax rate by that amount. For example,$800 was employment income reported in 2012. The income is below the maximum amount of 1,095. $800 was claimed on line 363 in Schedule 1 as Canada employment amount. The tax credit was$120 calculated by multiplying the lowest federal tax rate of 15% by the amount ($800). If your income was above the maximum amount, multiply the lowest marginal tax rate by the maximum amount, e.g.$35,000 was employment income reported in 2012. The maximum amount of $1,095 was claimed on line 363 in Schedule 1 as Canada employment amount. The tax credit was$164.25 calculated by multiplying 15% by \$1,095.
