Important Notes

This calculator provides estimates only. For exact payroll deductions, consult a payroll professional or use official government payroll guidelines. Rates and formulas may change annually.

Formula Used

CPP Calculation

CPP = Gross Pay × CPP Rate (5.95% for 2023)

EI Calculation

EI = Gross Pay × EI Rate (1.66% for 2023)

Income Tax Calculation

Income Tax = (Gross Pay - Deductions) × Tax Rate (varies by tax bracket)

Total Deductions

Total Deductions = CPP + EI + Income Tax + Other Deductions

Net Pay

Net Pay = Gross Pay - Total Deductions

Worked Example

Let's calculate payroll deductions for an employee with a gross pay of $3,500 and single tax status.

Step-by-Step Calculation

  1. CPP: $3,500 × 5.95% = $208.25
  2. EI: $3,500 × 1.66% = $58.10
  3. Income Tax: $3,500 × 20.5% (single tax bracket) = $717.50
  4. Total Deductions: $208.25 + $58.10 + $717.50 = $983.85
  5. Net Pay: $3,500 - $983.85 = $2,516.15

Example Results

For an employee earning $3,500:

Total Deductions: $983.85
Net Pay: $2,516.15
