Associate vs Employee Cost Calculator

Most clinic owners compare an associate and an employee on one number: the split percentage against the wage. That misses everything sitting underneath each option. Put the same billings through all three structures and see what your clinic actually keeps.

    Billings Employ Split Rent

    Best option on each row is in bold. Employment is close to a fixed cost, so it wins once they bill enough to cover it; a split scales with them, and rent never moves.

    What employing them costs you

    What they take home, before their own income tax

    An illustration using published 2026 federal and Ontario figures, not accounting, tax or legal advice for your clinic. It does not decide worker classification, which is set by the working relationship and can be reassessed by the CRA. Personal income tax is deliberately left out. Check the result against your own agreement before you rely on it.

    What the split percentage doesn't tell you

    Both halves of CPP stop at a ceiling

    As an employer you match the practitioner's CPP at 5.95% on earnings between the $3,500 basic exemption and $74,600, which caps your side at $4,230.45. Above that, CPP2 adds 4% on earnings up to $85,000, capped at another $416. So a $60,000 wage and a $110,000 wage do not carry proportional CPP. The cost flattens.

    EI costs you 1.4 times what it costs them

    The employee pays 1.63% on insurable earnings up to $68,900. You pay 1.4 times their premium, so your side maxes out at $1,572.30 against their $1,123.07.

    Employer Health Tax probably isn't your problem

    Ontario exempts the first $1,000,000 of payroll for eligible employers under $5 million in total payroll. A clinic with two or three practitioners is not close, so EHT is zero. It's worth saying plainly because the $490,000 exemption that several calculators still use stopped applying in 2019.

    The HST question inside a split

    A practitioner's treatment services are often exempt, which people take to mean HST never enters the arrangement. The clinic's share can be a different supply: if what you keep is really rent, reception and use of the facilities, that can be taxable. A practitioner making exempt supplies generally cannot recover the HST they pay, so it stops being a wash and starts being a cost. Which way it lands depends on how the agreement is written, so the calculator asks rather than assumes.

    Paying them an hourly rate instead?

    This page turns on how much they bill. If you're comparing a wage against a contractor's hourly rate, that comparison needs the hours nobody works taken out of it first.

    The cost is the easy half. How the agreement is worded decides the HST treatment and how a CRA review of the relationship goes. Wellspring works with Ontario wellness practices on exactly this.
