How to Calculate Payroll Deductions

To calculate payroll deductions, follow these steps:

Determine the employee's gross salary
Calculate CPP contributions:
CPP = (Gross Salary - CPP Exemption) × CPP Rate
Calculate EI premiums:
EI = (Gross Salary - EI Exemption) × EI Rate
Calculate income tax:
Tax = (Gross Salary - Tax Exemption) × Combined Tax Rate
Total deductions = CPP + EI + Tax

The calculator automates these calculations using the 2018 rates and your selected tax bracket.

Example Calculation

Let's calculate deductions for an employee with a gross salary of $50,000 in the 2018 tax bracket of 9.15% (Ontario) and 20.5% (Federal).

CPP Calculation:
CPP = ($50,000 - $3,500) × 4.95% = $234.75
EI Calculation:
EI = ($50,000 - $8,280) × 1.66% = $66.42
Tax Calculation:
Tax = ($50,000 - $10,582) × 9.15% = $344.25
Total Deductions:
$234.75 + $66.42 + $344.25 = $645.42

This means the employee's net pay would be $50,000 - $645.42 = $49,354.58.
