Calculations use 2026 federal and Ontario tax rates, CPP/CPP2, and EI figures. Pay-cycle figures divide the annual estimate across 52 weekly, 26 biweekly, 24 semi-monthly, or 12 monthly payments. Your real deductions can change during the year once EI or CPP limits are reached, and payroll rounding, credits, RRSP contributions, benefits, and other deductions can also change a paycheque.

Permanent median
$159,000
$107,508 take-home
Contract median
$119/hour
≈ $218,960 gross a year
At a median $119/hour, contract work grosses about $218,960 a year over 1,840 billable hours (230 days), 38% more than the $159,000 permanent median. That premium has to pay for what an employer would otherwise cover: paid holiday and sick days, pension contributions, and the gaps between contracts.
Contract and permanent benchmarks come from separate samples, so treat the gap as a guide rather than a like-for-like quote. See Quantitative Developer (C++ / Python) contract rates and contractor take-home →
