Contractor vs Employee Calculator (Canada)

What the contractor vs employee calculator does

The calculator answers whether the contract rate on offer is actually better than the salary you would earn doing the same work as staff. It takes an hourly rate, the hours you can realistically bill in a year, a competing salary and your province, then reports what you keep from each after tax and payroll contributions.

The headline numbers are rarely comparable. A contract at $95 an hour sounds large next to a salary, but the contractor pays both shares of CPP, gets no employer pension match, buys their own insurance, and is paid only for hours billed. The employee accepts a lower gross figure in exchange for paid leave, employer contributions and benefits. This tool puts both on the same footing.

Why the two are not the same money

An employee on a T4 has tax, CPP or QPP and EI withheld at source. The employer matches the CPP contribution and pays 1.4 times the employee’s EI premium, none of which appears on the pay stub, but it is real compensation.

A contractor receives the gross amount and settles everything afterwards. Business expenses come off first, which is a genuine advantage. Then self-employed CPP or QPP applies to net business income at double the employee rate, because no employer pays the other half. There is no EI premium and no EI entitlement. Tax is paid in instalments rather than at source, and GST or HST registration is required once billings pass the $30,000 small-supplier threshold.

A rate premium of 30% or 40% over the salaried equivalent can shrink to almost nothing once contributions, unbilled weeks and lost benefits are counted, or stay substantial in a low-tax province with large deductible expenses. Only the arithmetic tells you which.

How the calculation works

For the contractor, the tool multiplies your hourly rate by your billable hours for gross billings, subtracts deductible business expenses to reach net business income, then charges CPP or QPP at both the employee and employer share up to the year’s maximum pensionable earnings, plus the second-tier contribution between the first and second earnings ceilings. Quebec residents are charged QPP and the self-employed QPIP premium instead. Part of those contributions is deducted from income and part becomes a non-refundable credit, as the Income Tax Act splits them.

For the employee, the tool charges the employee share of CPP or QPP, the EI premium up to maximum insurable earnings (at the lower Quebec rate in Quebec), and QPIP in Quebec. Federal and provincial tax are applied using the current brackets and basic personal amounts, with the Ontario Health Premium and the Ontario surtax where they apply and the Quebec abatement for Quebec residents.

The value of employer-paid benefits and pension matching is then added to the employee’s net pay, since that is compensation you would give up by contracting. The difference between the two results is the contractor advantage, and the tool also solves for the hourly rate at which the two are equal.

A worked example

With the default inputs ($95 an hour for 1,600 hours, $8,000 of expenses, against a $110,000 salary with $9,000 of benefits, in Ontario), the contractor bills $152,000 and has $144,000 of net business income. After about $9,293 of CPP and $35,988 of tax, the contractor keeps about $98,720. The employee keeps about $80,666, or $89,666 counting benefits. The contract comes out about $9,054 a year ahead, and the break-even rate is $85 an hour.

Reading the break-even rate

The break-even hourly rate is the minimum you can charge, on the hours you entered, before the contract becomes worse than the salary. Below it, you are subsidizing the client. Comfortably above it, the surplus is your payment for the risk, the administration and the lack of paid leave.

Change the billable hours and watch the break-even rate move. Someone who bills 1,800 hours needs a much lower rate than someone who bills 1,200. Unbilled time is the most underestimated cost of contracting, because holidays, sick days, business development and administration are all unpaid.

Things the model leaves out

The comparison assumes an unincorporated sole proprietor; incorporation, salary and dividend mixes and retained earnings are a separate exercise. GST or HST is excluded because registered contractors collect and remit it rather than keeping it. Employer payroll levies such as Ontario’s Employer Health Tax are not part of either side.

The model also does not price job security, the value of a defined benefit pension, or the freedom to work for several clients. Those are real, and they are yours to weigh.

Before you sign

Run the numbers twice: with the hours you hope to bill, and with the hours you would bill in a bad year. If the contract still wins in the bad year, the decision is easy. If it only wins in the optimistic case, negotiate the rate rather than the hours.

Check the cash flow too. A contractor pays tax by instalment rather than at source, so the first year of contracting often ends with a large balance owing, and the second brings quarterly instalments on top. Set aside a share of every invoice from the first month in a separate account. Contractors who skip that step often find the arithmetic worked and the cash flow did not.

Register for GST or HST once your billings pass the small-supplier threshold, and confirm whether your client expects the quoted rate to include it. A rate agreed without that conversation can cost you the whole margin the calculator found.

All figures are estimates based on published federal and provincial rates for the current tax year and the details you enter. They are not tax, legal or financial advice. Speak to a Canadian accountant before changing how you are paid.
