Free tools for small and household employers. Every figure is computed from CRA's published T4127 Payroll Deductions Formulas (2026 editions) by a deterministic engine that is cross-checked against CRA's own PDOC calculator and T4032 tables to the cent before anything ships. No signup — everything runs in your browser and nothing you type leaves it.
Looking for CRA's own calculator? PDOC is on canada.ca, and the formulas are in CRA's T4127 guide. These tools add what PDOC doesn't do: work backwards from an agreed take-home pay to the gross salary. They also total your full employer cost in one number.

Salary plus your CPP match and 1.4× EI — your true statutory cost, their exact take-home, and what to remit to CRA each pay period. All 13 provinces and territories.
