Calculation Method

The calculator uses the following formulas to determine the payroll deductions:

CPP Employee = Gross Salary × CPP Rate (5.95%) EI = Gross Salary × EI Rate (1.66%) Income Tax = (Gross Salary - Deductions) × Tax Rate (varies by filing status) CPP Employer = Gross Salary × CPP Rate (5.95%) EI Premium = Gross Salary × EI Premium Rate (1.40%)

The net pay is calculated by subtracting all deductions from the gross salary.

Deduction Rate (2023)
CPP Employee 5.95%
EI 1.66%
CPP Employer 5.95%
EI Premium 1.40%

Worked Example

Let's calculate the payroll deductions for an employee with a gross salary of $50,000 and a filing status of "Single".

  1. CPP Employee: $50,000 × 5.95% = $2,975
  2. EI: $50,000 × 1.66% = $830
  3. Income Tax: ($50,000 - $2,975 - $830) × 20.5% (example rate) ≈ $8,285
  4. CPP Employer: $50,000 × 5.95% = $2,975
  5. EI Premium: $50,000 × 1.40% = $700

The total deductions would be approximately $7,760, and the net pay would be $42,240.
