Mortgage payment in 2026: how it works, with a worked example

Verified for tax year 2026: Updated By Nishant Malik

Enter the price, your down payment and the rate, and scroll: your payment, what the home costs each month, whether it fits your income, the cash you need on closing day, what a bigger down payment changes, how much is interest over the years, and the costs people forget. Every figure follows CMHC and Canadian mortgage rules.

How this calculator works

A mortgage payment is the level amount that repays the loan, with interest, over the amortization period. The standard formula is:

Payment = P × i ÷ (1 − (1 + i)−n), where P is the amount borrowed, i is the interest rate per payment period and n is the total number of payments.

The Canadian twist is in i. Section 6 of the Interest Act requires fixed-rate mortgage interest to be stated as compounded yearly or half-yearly, and lenders use half-yearly. So the rate per month is not the annual rate divided by 12; it is (1 + rate ÷ 2)1/6 − 1. At 5% that is 0.4124% per month rather than 0.4167%, which is why Canadian payments are slightly lower than a US calculator would show.

Mortgage default insurance is required whenever the down payment is under 20% of the price. The calculator applies CMHC’s published premium table to the loan-to-value ratio, adds the 0.20% surcharge for amortizations over 25 years, and adds the premium to the mortgage. Provincial sales tax on the premium, in Ontario, Quebec and Saskatchewan, is shown separately because it is due in cash at closing.

Accelerated payments take the monthly payment and split it in two (bi-weekly) or four (weekly). Because there are 26 bi-weekly periods, that is the equivalent of 13 monthly payments a year, and the extra payment shortens the amortization. The calculator runs the full schedule to find the real payoff date.

Worked example: $600,000 home, 10% down, 4.5% over 25 years

Assumptions

  • The rate stays constant for the whole amortization. In practice a Canadian mortgage is a series of terms (often 5 years) that renew at new rates; the payment shown is for the first term and the interest total assumes the rate never changes.
  • Semi-annual compounding is used for every rate, including variable rates.
  • Payments are principal and interest only. Property tax, home insurance, condo fees and utilities are extra.
  • The 30-year amortization on an insured mortgage is only available to first-time buyers and buyers of newly built homes; the calculator applies the premium surcharge but does not check eligibility.
  • Insurance figures use CMHC’s table; Sagen and Canada Guaranty charge the same standard premiums.

Questions people ask

Why is my Canadian mortgage payment lower than an American calculator shows?
Canadian fixed-rate mortgages compound semi-annually by law (Interest Act, section 6), while US mortgages compound monthly. At 5% the effective monthly rate is 0.4124% in Canada versus 0.4167% in the US. On a $500,000 mortgage over 25 years that is $2,908 a month here versus $2,923 there.
How much does CMHC mortgage insurance cost in 2026?
The premium depends on your loan-to-value ratio: 2.40% of the loan with 15% to 20% down, 3.10% with 10% to 15% down, and 4.00% with 5% to 10% down. Choosing a 30-year amortization adds 0.20%. The premium is added to your mortgage, but the provincial sales tax on it (8% in Ontario, 9% in Quebec, 6% in Saskatchewan) must be paid in cash at closing.
What is the minimum down payment in Canada?
5% of the first $500,000 of the price and 10% of the portion above that, up to the $1,499,999 insured limit. At $1.5 million and above the home cannot be insured, so 20% down is required. With less than 20% down at any price, mortgage default insurance is mandatory.
Can I get a 30-year amortization?
With a down payment under 20%, 30 years is allowed only if at least one buyer is a first-time home buyer or the home is newly built; otherwise the maximum is 25 years. With 20% or more down, lenders can offer 30 years to anyone, and some go longer. A longer amortization lowers the payment but increases total interest substantially.
What is the difference between bi-weekly and accelerated bi-weekly payments?
A regular bi-weekly payment is the monthly amount times 12 divided by 26, so you pay the same total each year. An accelerated bi-weekly payment is simply half the monthly payment, paid 26 times, which equals 13 monthly payments a year. That extra month goes straight to principal and typically shortens a 25-year mortgage by about three years.
What rate do I need to qualify at under the stress test?
Lenders must qualify you at the greater of your contract rate plus 2 percentage points and 5.25%. At a 4.5% contract rate you must show you could afford payments at 6.5%. The rule applies to insured and uninsured mortgages, although since November 2024 uninsured borrowers switching lenders at renewal without changing their loan are exempt.
Does the payment include property tax and home insurance?
No. The payment shown is principal and interest only. Lenders usually add a monthly property-tax instalment to the payment, and you pay home insurance separately. Add both when checking what you can afford, and remember condo fees if they apply.
How do variable-rate mortgages compound?
There is no statutory rule. Most lenders compound variable rates semi-annually like fixed rates, but some compound monthly. The calculator assumes semi-annual compounding for all rates; if your lender compounds monthly, your payment will be slightly higher.
What does a mortgage really cost per month beyond the payment?
Add property tax (roughly 0.5% to 1.2% of the price a year depending on the city), heat and utilities, home insurance and any condo fees. On a $600,000 home that is often $600 to $900 a month on top of principal and interest, which is why lenders test your budget with those costs included.
How much cash do I need on closing day?
Your down payment plus closing costs: land transfer tax (rebated in part for first-time buyers in Ontario, BC, PEI and Quebec), the provincial sales tax on the CMHC premium if you have one, legal fees and disbursements, title insurance, and adjustments for prepaid property tax or utilities. Budget 1.5% to 4% of the price beyond the down payment; the calculator itemizes it.
Fixed or variable in 2026?
A variable rate is usually lower today but moves with the Bank of Canada's policy rate. The calculator shows the average variable rate over your term at which the two cost the same; if you expect rates to stay below that, variable wins. Variable-rate penalties are also smaller (three months' interest) if you break the mortgage.
What happens at the end of my 5-year term?
The balance shown at the end of the term is what you renew, at whatever rates are then. Only the interest and principal of the first term are certain; the mortgage renewal calculator shows what a rate change does to your payment at that point.
