Worked Example

Let's calculate payroll deductions for an employee earning $2,500 per month.

Deduction	Calculation	Amount
EI Premiums	$2,500 × 1.63%	$40.75
CPP Contributions	$2,500 × 4.95%	$123.75
Income Tax	Federal + Ontario tax on $2,500	$375.00
Total Deductions	EI + CPP + Income Tax	$539.50
Net Pay	Gross Pay - Total Deductions	$1,960.50

For this example, the employee would receive $1,960.50 after all deductions.
