Default insurance is required when the down payment is under 20%. Insurance is not available on purchases of $1.5M or more, or on amortizations over 25 years except where the borrower qualifies for an extended-amortization insured program.

How this mortgage payment calculator works

This calculator uses the Canadian convention: fixed-rate mortgages in Canada compound semi-annually, not in advance, which is different from the monthly compounding used in the United States. The periodic rate is derived as (1 + annual rate ÷ 2)2÷n − 1, where n is the number of payments per year. Using American monthly compounding overstates a Canadian payment by a small but real amount, and a lot of online calculators get this wrong.

Enter the purchase price and your down payment and the calculator works out the loan-to-value, adds the mortgage default insurance premium where one is required, and gives you the payment on the total insured amount. It also shows you the balance you will still owe at the end of your term — the number that actually matters when you renew.

What is not included. This is a principal-and-interest payment. Property tax, condo or maintenance fees, heat, and home insurance are on top, and lenders count them when they test whether you qualify. As a rule of thumb, budget 1% to 1.5% of the property value per year for property tax, and add condo fees at their actual amount.

Payment frequency: how accelerated payments actually save money

Bi-weekly and weekly payments are not automatically cheaper. A standard bi-weekly payment is simply your annual total divided into 26 pieces — you pay the same amount over a year and save only a small amount of interest from paying slightly earlier.

Accelerated bi-weekly is different. It takes your monthly payment and halves it, then charges that half every two weeks. Because there are 26 two-week periods in a year, you make the equivalent of 13 monthly payments instead of 12. That extra payment goes almost entirely to principal, and on a typical 25-year amortization it knocks roughly three years off the mortgage.

What the stress test does to the amount you can borrow

Federally regulated lenders must qualify you at the minimum qualifying rate: the greater of your contract rate plus 2% or 5.25%. At today's best insured 5-year fixed of 4.09%, that means qualifying at 6.09% even though you pay 4.09%.

The practical effect is that the mortgage you qualify for is roughly 15% to 20% smaller than the mortgage your actual payment would suggest. The one important exception is at renewal: since November 2024, an uninsured straight switch to another federally regulated lender is exempt from the qualifying rate as long as you do not increase the loan amount or the amortization.

Down payment rules in Canada

Minimum down payment is tiered by purchase price, and the tiers stack rather than replace each other.

  • Insured mortgages are capped at a purchase price under $1.5M.
  • First-time buyers, and all buyers of newly built homes, can access a 30-year insured amortization — at a 0.20% premium surcharge.
  • The premium can be added to your mortgage. The provincial sales tax on the premium (8% in Ontario, 9% in Quebec, 6% in Saskatchewan) cannot — that is cash at closing.

Frequently asked questions

Canadian fixed-rate mortgages compound semi-annually, not in advance. The periodic rate is (1 + annual rate ÷ 2)^(2÷n) − 1 where n is payments per year, and the payment is P × r ÷ (1 − (1 + r)^−N). This produces a slightly lower payment than the monthly-compounding formula used in the United States.

No. It calculates principal and interest only. Property tax, condo or maintenance fees, heat and home insurance are additional, and lenders include them when testing your GDS and TDS ratios. Budget roughly 1% to 1.5% of property value per year for property tax.

Standard bi-weekly divides your annual payment total into 26 pieces, so you pay the same amount each year. Accelerated bi-weekly halves your monthly payment and charges it every two weeks, which means 26 half-payments — the equivalent of 13 monthly payments a year. That extra payment goes to principal and typically shortens a 25-year mortgage by about three years.

The premium depends on loan-to-value: roughly 2.80% at 85% LTV, 3.10% at 90%, and 4.00% at 95%, plus a 0.20% surcharge if the amortization exceeds 25 years. It is calculated on the mortgage amount and can be added to the loan. Insurance is not available at all if the purchase price is $1.5M or more.

Use the rate you have actually been quoted. If you do not have one, 4.09% is a reasonable placeholder — that is the best available insured 5-year fixed as of August 2026. Uninsured 5-year fixed is nearer 4.29% and 5-year variable near 3.35%.

Because that balance is what you renew. Two mortgages with identical payments can leave very different balances after five years depending on rate and amortization, and the smaller balance is worth real money at renewal. It is the number lenders never put on the front of the offer.

You can, by entering your current balance as the purchase price and zero as the down payment. For a proper comparison, use the mortgage renewal calculator or the refinance calculator, which are built to compare two scenarios side by side.

It is an accurate estimate of the payment on the numbers you entered, but the rate you are offered depends on your credit, income, property type, loan-to-value and lender. Send us the file and we will confirm the real rate at no cost.
