How to calculate payroll step by step

Payroll calculation involves five essential steps:

1. Collecting employee information and hours worked.
2. Calculating gross pay.
3. Applying deductions and taxes.
4. Adding benefits and employer contributions.
5. Determining net pay and issuing pays.

For businesses in Canada, payroll can be time-consuming if done manually. Following a structured method or relying on payroll software such as Nethris payroll service, helps ensure accuracy, compliance and efficiency.

Step 1 – Collect employee information and hours worked

The foundation of payroll begins with accurate employee data.

Employers must gather:

• Employment contracts and wage agreements.
• Hourly rates or annual salaries.
• Overtime eligibility and pay rules.
• Vacation accruals and sick leave.

Accurately tracking hours worked (using timesheets or software) ensures employees are fairly compensated and employers remain compliant with provincial labour standards.

Step 2 – Calculate gross pay

Gross pay represents an employee’s earnings before deductions.

• Hourly employees: Multiply the hourly rate by total hours worked, including overtime.
• Salaried employees: Divide the annual salary by the amount of pay periods.
• Additions: Commissions, bonuses, allowances and shift premiums.

Gross pay is the first major figure employers must calculate before moving to deductions.

Step 3 – Apply payroll deductions and taxes

Canadian payroll requires specific statutory deductions:

• CPP or QPP: Canada Pension Plan (or Québec Pension Plan) contributions.
• EI: Employment Insurance premiums.
• Federal and provincial income taxes.

Additionally, some deductions are voluntary, such as:

• Group RRSP contributions
• Union dues
• Health or dental insurance premiums

Employers must remain compliant with federal and provincial laws. The Canada Revenue Agency (CRA) provides detailed guidance on payroll deductions.

Step 4 – Add benefits and employer contributions

Beyond deductions, employers must add certain benefits and contributions:

• Employer-paid health insurance premiums.
• Pension plan contributions.
• Statutory benefits (e.g., EI employer portion, CPP/QPP employer match).

Step 5 – Calculate net pay and issue pays

The final step is to determine net pay, calculated as:

Net Pay = Gross Pay – Deductions + Benefits

Payment is then issued through:

• Direct deposit (most common in Canada)
• Cheques
• Paycards (less frequent but used in some industries)

Transparency is crucial this each employee should receive a pay stub showing gross pay, deductions, contributions and net pay.
