Would this be a good approximate for take home pay each year if one is employed?

In the T4 slip,

Employment Income in Box 14
- Box 40 (other benefits)
- EI contribution
- CPP contribution
- tax paid
- RRSP contribution
= approximate take home pay

If I am missing a few other pay deductions, please do let me know. It doesn't have to be down to exact figures but just a very good estimate of one's take home pay each year.

Thank you.
