Net proceeds = sale price, minus the commission plus taxes (5% GST + 9.975% QST = 14.975% on the commission), minus the mortgage balance, minus the prepayment penalty, minus the notarized discharge and the certificate of location if it has to be redone. The calculator below does the full calculation live.
Your calculation
Illustrative estimate before prorated tax adjustments and before any income tax (cottage, rental). Your final statement is prepared by the notary.
What the calculator adds up (and why)
Four blocks come out of the sale price. The broker's commission, freely negotiated (often around 5%), plus 14.975% in taxes on that commission. The repayment of your loan: remaining balance plus any prepayment penalty. The fixed costs: notarized discharge (a few hundred dollars) and the certificate of location if it has to be redone. And at the final statement, the municipal and school tax adjustments prorated to the date of sale.
The commission covers the full marketing effort (photos, listing, showings, negotiation) and is usually shared between the seller's broker and the buyer's broker; the detailed mechanics are in our commission guide. The penalty is the only real unknown in the calculation: from zero to several thousand dollars depending on your rate and your term. One call to your lender gives you the exact figure, and our mortgage penalty guide explains how it is computed and how a mortgage transfer can eliminate it completely when you sell to buy again.
How to make the bottom number bigger
Three levers move the net proceeds: the sale price obtained (by far the most powerful), the mortgage penalty (negotiable or avoidable through a transfer), and the timing of the sale relative to your term. A well-prepared listing that brings in 2% more on the price adds more to the net than any saving on fixed costs.
- Price first. On $500,000, getting 2% more brings $10,000 gross, about $8,500 net after the taxed commission. Preparation, photos and the right asking price are the real levers: see the method in our guide to the cost of selling.
- Then the penalty. Free prepayment statement from your lender, mortgage transfer if you are buying again, or timing the sale with the end of your term.
- The asking price, not the municipal assessment. The market prices on recent comparables: our guide municipal assessment explained in English shows why the tax bill says nothing about your sale price.
- The certificate of location. Still valid and compliant (no change to the property): $0. To be redone: count a few hundred dollars and two to several weeks of surveyor lead time; order it early.

Frequently asked questions about seller net proceeds
How do you calculate the net proceeds of a real estate sale in Quebec?
Net proceeds = sale price, minus the broker's commission plus taxes (5% GST and 9.975% QST, or 14.975% on the commission), minus your mortgage balance, minus the prepayment penalty if there is one, minus the discharge fees at the notary and the certificate of location if it has to be redone. Prorated municipal and school tax adjustments are added to the final statement, in one direction or the other.
Is the broker's commission taxable?
Yes. The 5% GST and 9.975% QST apply to the commission, 14.975% in total. A 5% commission on a $500,000 sale represents $25,000, plus $3,743.75 in taxes, for a total of $28,743.75. That is why the overall cost of selling is usually quoted at 5% to 7% of the price, taxes included.
How do I find out my mortgage penalty before selling?
Call your lender and ask for the prepayment statement: it is free and without obligation. On a variable rate, the penalty is generally three months of interest; on a fixed rate, it is the higher of three months of interest and the interest rate differential, which can reach several thousand dollars. If you are buying another property, also ask whether your mortgage is portable: a transfer can eliminate the penalty.
Do I have to pay tax on the profit from selling my house?
Not if it was your principal residence for every year you owned it: the principal residence exemption wipes out the capital gain, but the sale must still be reported on your tax returns. A cottage, a rental building or a property that was not always your principal residence generates a taxable capital gain instead. This calculator does not account for income tax: consult your accountant for non-exempt cases.
Illustrative tool as of September 13, 2026. 5% GST and 9.975% QST apply to the brokerage commission; the commission rate is freely negotiated between you and your broker. The calculator does not account for prorated adjustments (taxes, heating oil, condo fees), income tax on a non-exempt gain or the cost of preparing the property. The official statement of sale proceeds is prepared by the acting notary. Version française de ce calculateur.
