Backend Engineer Day Rate Calculator: Canada 2026

Multiply your hourly rate by your expected billable hours per year (1,840 is a common default: 230 billable days x 8 hours/day, accounting for 9 Ontario statutory holidays, a paid-leave-equivalent buffer, and unpaid downtime between contracts), then adjust for the contractor loading you're charging on top of an equivalent salary. The calculator above does this both ways: salary to rate, or rate back to an equivalent salary.

It depends on your structure. Incorporated contractors, who pay themselves a salary from their own corporation, typically load 15-25% on top of an equivalent salary rate. Unincorporated sole proprietors typically load 20-30%, since they pay both the employee and employer halves of CPP with no employer to split the contribution.

It depends on your structure. An incorporated contractor paying themselves a salary has CPP deducted the normal employee way. An unincorporated sole proprietor pays both the employee and employer halves of CPP on net business income and is not required to pay EI premiums at all. Always confirm your structure before comparing a quoted rate to a permanent salary.

Both incorporated and sole proprietor contractors pay Income Tax at the same progressive federal + Ontario personal rates as an employee on their respective income. Canada has no IR35-style test that changes an individual contractor's personal tax rate; the CRA's personal-services-business rules instead affect the corporate tax rate an incorporated contractor's own company pays, which this MVP does not model.

At CA$91/hour over 1,840 billable hours a year (230 billable days x 8 hours/day), the gross annual contract income is CA$167K. This is a 36% gross premium over the Backend Engineer permanent salary median of CA$123K/year. The premium compensates contractors for self-funded CPP (doubled for sole proprietors), leave, job security, and business overheads that a permanent employer covers on an employee's behalf.
