Weekly Payroll Tax Calculator
About This Weekly Payroll Tax Tool
This weekly take-home pay calculator provides a quick approximation of payroll deductions in Canada. It uses effective federal and provincial income tax rates, weekly CPP/QPP, and EI estimates to show a clear breakdown of weekly deductions and net pay. For planning, budgeting, or paycheck comparison across provinces, it is a practical weekly payroll estimator.
How Weekly Deductions Are Estimated
1) Taxable Weekly Income
Taxable Weekly Income = Weekly Gross Pay − Pre-Tax Deductions + Taxable Benefits.
2) Federal and Provincial/Territorial Income Tax (Effective Rate)
The calculator applies simplified effective rates to approximate combined bracket impacts over annualized income. You can override these rates in Advanced Assumptions to align with current CRA/Revenue Québec guidance or your individual withholding pattern.
3) CPP or QPP Contributions
CPP/QPP is applied to weekly pensionable earnings up to the yearly maximum. The basic exemption is prorated weekly to avoid contributions on the exempt portion. Values can be adjusted for the current tax year.
4) EI Premiums
EI premiums are calculated as a percentage of weekly insurable earnings up to the annual insurable maximum. Quebec uses a distinct EI rate. Both values are editable.
5) Estimated Weekly Net Pay
Estimated Net Pay = Weekly Gross Pay − (Federal Tax + Provincial Tax + CPP/QPP + EI + Other Adjustments).
Notes and Limitations
- Results are illustrative and use simplified effective tax rates. Official payroll withholdings use detailed CRA/Revenue Québec formulas and credits.
- CPP/QPP and EI stop after annual maximums; this tool does not track year-to-date balances.
- Self-employment and special payroll situations (bonuses, retroactive pay, taxable benefits breakdown, QPIP) are not covered.
- Always verify provincial and federal rates for the current tax year before payroll processing.
Weekly Payroll Tax FAQs
Does this tool show weekly net pay for Canada only?
Yes. It focuses on Canadian weekly payroll deductions and take-home pay.
How are effective tax rates chosen?
They are simplified averages intended to approximate marginal bracket outcomes. You can edit them in the assumptions panel.
Why do Quebec values differ?
Quebec uses QPP instead of CPP and has a different EI rate. Provincial income tax rates also differ from other provinces.
Can I include RRSP or other pre-tax deductions?
Yes. Enter them in the Pre-Tax Deductions field to reduce taxable weekly income before tax and contributions.
Does this replace official payroll calculations?
No. It provides a quick weekly estimate. Employers should use official CRA/Revenue Québec payroll tools for compliance.
Is overtime included?
Overtime can be added into Weekly Gross Pay, but the calculator does not compute overtime rules by itself.
