The Canadian Mortgage Calculator is mainly intended for Canadian residents and uses the Canadian dollar as currency, with interest rate compounded semi-annually.
When it comes to purchasing a house in Canada, there is normally one factor that is considered, how much will the mortgage payment be and can I reasonably afford it over the long term? The Canadian Mortgage Calculator makes that question easy and fast to respond to by estimating the payment, providing a complete amortization schedule and allowing you to test various down payments, payment frequencies, interest rates and prepayments.
Our in-built Tog calculator can be used to estimate:
Canadian mortgages have a few important differences compared with other countries most notably, interest is commonly compounded semi-annually and payment frequency options like accelerated bi-weekly are extremely popular.
To get an accurate estimate, you’ll want to enter realistic numbers for these key inputs:
Your down payment changes the loan size and may affect whether you need mortgage default insurance.
In Canada, minimum down payment rules typically work like this:
Some tools use “Mortgage Amount” directly (the amount you borrow). Others start with purchase price and down payment, then calculate the loan.
Enter the annual rate you expect to negotiate. Even small rate changes can significantly affect total interest over a long amortization.
This is one of the most misunderstood parts of Canadian mortgages:
Canada’s official tools explicitly call out this difference so borrowers don’t confuse the two.
Important rule update: As of December 15, 2024, if your down payment is less than 20%, the maximum amortization may be limited (for example, 30 years only in certain cases like first-time buyers or new builds; otherwise 25 years).
A good Canadian mortgage calculator should let you compare payment schedules like:
Why do Canadians love accelerated options? Since faster schedules normally equate to an additional payment of one month annually, this will assist you in saving on interest and reducing your time of amortization.
When you calculate, focus on these outputs:
Many calculators show:
This is helpful because your true monthly “housing cost” is often more than principal and interest.
An amortization schedule shows, payment by payment:
In the early years, a larger share of your payment typically goes toward interest. As the balance drops, more of the payment shifts to principal.
A big reason to use a calculator is to understand the “true cost” of borrowing. Tools often display total interest over the amortization, which is crucial when comparing:
Many Canadian mortgage calculators let you model prepayments, like:
Prepayments generally apply directly to the principal balance, which can:
Ask your mortgage agreement regarding prepayment options and potential penalties (especially on closed mortgages).
Mortgage default insurance (also CMHC-insured mortgages) is usually required when you have less than 20 as a down payment. It may help to cost more to borrow, but also allows smaller down payments.
When qualifying for a mortgage in Canada, lenders typically apply a “stress test.” The qualifying rate is commonly the greater of:
This would not make you pay the higher rate but is used to make you sure that you will be able to make payments had there been an increase in the rate as well.
Many Canada-specific calculators note that Canadian mortgage interest is commonly compounded semi-annually, which can make results differ from calculators designed for other countries.
It often can be—accelerated payments may effectively add an extra monthly payment each year, which can reduce interest and shorten amortization.
Calculators are excellent estimates, but lenders may calculate slightly differently and may include/structure items like insurance premiums, compounding conventions, or payment rounding in their own way.
