Reverse Payroll Calculator Ontario

Reverse payroll is a method used in Ontario to determine the employer's contribution to payroll deductions. This calculator helps you compute the reverse payroll amount based on gross pay and applicable deductions.

What is Reverse Payroll?

Reverse payroll is a calculation method used to determine how much an employer should contribute to payroll deductions when the net pay is known. This is particularly useful in Ontario for determining the employer's contribution to CPP (Canada Pension Plan) and EI (Employment Insurance) deductions.

The process involves working backward from the net pay to determine the original gross pay before deductions. This is important for payroll reconciliation and ensuring compliance with Ontario's payroll regulations.

How to Calculate Reverse Payroll

Calculating reverse payroll involves several steps to ensure accuracy. Here's a simplified process:

Determine the net pay amount you want to achieve.
Identify the applicable deductions (CPP, EI, income tax, etc.).
Calculate the total deductions based on the gross pay.
Adjust the gross pay until the net pay matches your target.

This process can be complex, especially when dealing with multiple deductions and tax brackets. Our calculator simplifies this by automating the calculations based on the inputs you provide.

Reverse Payroll Formula

The basic formula for reverse payroll is:

Gross Pay = (Net Pay + Deductions) / (1 - Total Deduction Rate)

Where:

Gross Pay - The total amount paid to the employee before deductions
Net Pay - The amount the employee takes home after deductions
Deductions - Total amount deducted from gross pay (CPP, EI, income tax, etc.)
Total Deduction Rate - Combined rate of all deductions

This formula helps in determining the required gross pay to achieve a specific net pay after all deductions.

Example Calculation

Let's say you want to achieve a net pay of $2,000 after deductions. The applicable deductions are:

CPP (5.95%)
EI (1.66%)
Income Tax (20%)

The total deduction rate is 5.95% + 1.66% + 20% = 27.61%.

Using the formula:

Gross Pay = ($2,000 + ($2,000 × 0.2761)) / (1 - 0.2761)

Gross Pay = ($2,000 + $552.20) / 0.7239

Gross Pay ≈ $2,744.44

This means you need to pay approximately $2,744.44 in gross pay to achieve a net pay of $2,000 after deductions.
