Brossard mortgage calculator
What a Brossard mortgage costs each payment, how long it runs, what it costs in total, and how much sooner it ends if you pay a little more. Built on semi-annual compounding and a 25-year amortization, and it charges the Quebec sales tax on the mortgage insurance premium, which is the highest in the country and the line most calculators leave out entirely.

The purchase
20.0% down. The minimum on this price is $46,380. At 20% or more there is no insurance premium.
Lenders qualify you at the higher of this rate plus 2 points and 5.25%: 6.34% here, a payment of $3,769.75.
The contract length, not the amortization. At the end of it you renew at whatever rates are then available.
Paying it down faster
Most lenders cap annual prepayments at 10–20% of the original principal, and charge a penalty above it. Check your own commitment before planning around a large lump sum.
Where the money goes, year by year
Early payments are almost all interest. The crossover (the year principal finally exceeds interest) is the real shape of an amortized loan, and it is much later than most people expect.

Quebec taxes your mortgage insurance, and it is payable in cash
If you put down less than 20% the loan needs default insurance, and the premium is a percentage of the loan that rises as the down payment falls. Everywhere in Canada that premium is capitalized into the mortgage, so it costs you interest rather than cash. Quebec then does something Alberta and British Columbia do not: it charges its 9% tax on insurance premiums against it, and that tax cannot be added to the loan. It is a cheque at closing.
On this house, at 10% down, the premium is about $19,915, and the Quebec tax on it is $1,792, due in cash on top of your down payment and your closing costs. Ontario charges 8% and would take $1,593; Alberta and British Columbia charge nothing at all. It is the single most commonly missed line on a Quebec purchase, and the calculator above shows it rather than burying it.
The welcome tax is not due at closing, which is why people are caught by it
Quebec's droit de mutation on the median detached house here is about $8,818, charged to the buyer. Unlike a land transfer tax anywhere else in Canada, the notary does not collect it at closing: the municipality bills it some months later, once the transfer has been published and the roll updated. The money is owed either way, and a great many buyers have spent it by the time the bill arrives. The transfer duty modelled here is the provincial floor: 0.5%, 1.0% and 1.5%. Quebec lets every municipality raise the rate on any bracket above $500,000 to as much as 3%, and many in this region have. Check the municipality's own by-law before treating the closing cost here as yours, on a purchase over $500,000 it is a floor rather than an estimate.
Semi-annual compounding, and why the American number would be wrong
A Canadian fixed-rate mortgage compounds twice a year by law, not twelve times, which makes the same nominal rate slightly cheaper here than it would be in the United States. This site runs both conventions and no page borrows the other country's arithmetic: the Charlotte pages compound monthly over thirty years, and every Canadian page, this one included, does not.
The term is not the amortization, and renewal is the real risk
The 25 years above is the amortization; the rate is fixed only for the term, usually five years, after which the balance renews at whatever rates are then. The calculator shows the balance at the end of the term for exactly that reason. An accelerated biweekly schedule is twenty-six half-payments a year: thirteen monthly payments' worth of money rather than twelve, and it is the single most effective thing most borrowers can do, though it is nothing cleverer than paying about 8% more each year.
What this cannot tell you
The payment above is principal and interest, plus the insurance premium where it applies. Your actual monthly cost also includes municipal tax, on the $713,800 median detached house in Brossard that is $327 a month at 0.55% of roll value, plus school tax, which in Quebec is separate, provincial, billed once a year and not in any figure on this page, and roughly $110 in home insurance.
