Formula Used

The Ontario Payroll Calculator uses the following formulas to calculate payroll deductions:

Income Tax Calculation

Ontario income tax is calculated using progressive tax brackets. The formula is:

Tax = (Taxable Income × Tax Rate) - (Tax Credit × Tax Rate)

Where Taxable Income is the employee's earnings minus any tax credits.

CPP (Canada Pension Plan)

CPP is calculated as:

CPP = (Gross Income × CPP Rate) - (Basic Exemption × CPP Rate)

The current CPP rate is 5.1% for employees and employers combined.

EI (Employment Insurance)

EI premiums are calculated as:

EI = Gross Income × EI Rate

The current EI rate is 1.63% for employees and employers combined.

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

Worked Example

Let's calculate payroll for an employee earning $2,500 per month in Ontario:

Deduction	Calculation	Amount
Income Tax	(2,500 × 20.5%) - (11,475 × 20.5%)	$357.50
CPP	(2,500 × 5.1%) - (3,500 × 5.1%)	$63.75
EI	2,500 × 1.63%	$40.75
Total Deductions	357.50 + 63.75 + 40.75	$462.00
Net Pay	2,500 - 462.00	$2,038.00

For this employee, the total payroll deductions would be $462.00, leaving a net pay of $2,038.00.
