Calculate your monthly take-home pay in Ontario with our free tax calculator. This tool estimates your net income after federal and provincial taxes, Canada Pension Plan (CPP), and Employment Insurance (EI) deductions.
How the Ontario Tax Calculator Works
The Ontario tax calculator estimates your monthly take-home pay by applying Ontario's tax rates, CPP, and EI deductions to your gross monthly salary. The calculation follows these steps:
- Calculate annual gross income from your monthly salary
- Apply Ontario's progressive tax rates
- Subtract federal taxes
- Calculate CPP and EI deductions
- Convert the net annual income back to monthly take-home pay
This calculator provides an estimate. Actual tax deductions may vary based on your specific situation, tax credits, and deductions.

Enter your gross monthly salary in the calculator and click "Calculate". The tool will display your estimated monthly take-home pay, along with a breakdown of taxes and deductions.
The calculator includes:
- Gross monthly salary input
- Estimated monthly take-home pay

Formula Used
The calculation follows these steps:
- Convert monthly salary to annual:
annualGross = monthlySalary × 12 - Calculate Ontario provincial taxes using progressive brackets
- Calculate federal taxes using progressive brackets
- Calculate CPP (5.95% of annual gross, capped at $3,500)
- Calculate EI (1.66% of annual gross, capped at $869.25)
- Calculate net annual income:
annualNet = annualGross - (provincialTax + federalTax + CPP + EI) - Convert back to monthly take-home pay:
monthlyNet = annualNet / 12
Worked Example
For a gross monthly salary of $3,000:
- Annual gross income: $3,000 × 12 = $36,000
- Ontario provincial taxes: $4,200 (based on 2023 rates)
- Federal taxes: $5,400 (based on 2023 rates)
- CPP: $2,142 (5.95% of $36,000)
- EI: $600 (1.66% of $36,000)
- Annual net income: $36,000 - ($4,200 + $5,400 + $2,142 + $600) = $23,658
- Monthly take-home pay: $23,658 / 12 ≈ $1,972
This example shows that with a $3,000 monthly salary, your estimated monthly take-home pay would be approximately $1,972 after taxes and deductions.
