Worked Example

Let's calculate deductions for someone earning $50,000 gross per year in Ontario.

Step 1: Calculate Income Tax

Using the 2023 tax brackets:

$48,535 × 15% = $7,280.25
Remaining $1,465 × 20.5% = $298.85
Total income tax = $7,579.10

Step 2: Calculate CPP

$50,000 × 5.95% = $2,975

Step 3: Calculate EI

$50,000 × 1.66% = $830

Step 4: Calculate Total Deductions

$7,579.10 (tax) + $2,975 (CPP) + $830 (EI) = $11,384.10

Step 5: Calculate Net Pay

$50,000 - $11,384.10 = $38,615.90

Result

For a $50,000 gross income, the total deductions would be $11,384.10, leaving a net pay of $38,615.90.
