Use this free Canadian mortgage calculator to estimate your monthly mortgage payment in seconds. Enter your purchase price, down payment, interest rate, and amortization period. The calculator returns your payment amount, total interest paid, and a breakdown you can use to compare mortgage options before talking to a lender.
This tool gives you a planning estimate. It does not replace a mortgage pre-approval or professional financial advice.
Calculate Your Monthly Mortgage Payment
To calculate your monthly mortgage payment, you need four numbers:
- Purchase price of the home
- Down payment amount or percentage
- Interest rate (fixed or variable)
- Amortization period in years
Enter those values and the calculator instantly shows your estimated payment. You can also adjust the payment frequency to see biweekly or accelerated options.
The result is an estimate based on the inputs you provide. Actual payments from a lender may differ due to fees, mortgage default insurance, or rate changes.
Purchase Price of Your Home
The purchase price of your home is the starting point for every mortgage calculation. It determines your mortgage amount after subtracting the down payment.
In Canada, minimum down payments follow a tiered rule:
- 5% on the first $500,000 of the purchase price
- 10% on the portion between $500,000 and $1,499,999
- 20% on homes priced at $1,500,000 or more
A higher down payment reduces your mortgage principal and lowers your monthly payment. If your down payment is less than 20%, you will also need mortgage default insurance, which adds a premium to the total mortgage amount.
Canadian Mortgage Rates
Your interest rate has a direct effect on every payment you make. Even a small difference, say 0.25%, changes the total interest paid over the life of your mortgage by thousands of dollars.
Canadian mortgage rates fall into two main categories:
- Fixed rate: The interest rate stays the same for the entire mortgage term. Your payment amount is predictable.
- Variable rate: The rate moves with the lender's prime rate. Payments may increase or decrease during the term.
Rate quotes change frequently. Enter the rate your lender has offered, or use a current posted rate as a starting point. The calculator lets you compare scenarios side by side so you can see how different rates affect your payment.
Amortization and Mortgage Term
These two terms sound similar but mean different things.
Amortization period is the total time to repay the full mortgage. In Canada, the most common amortization is 25 years. If your down payment is less than 20%, the maximum insured amortization is 25 years. With 20% or more down, some lenders allow up to 30 years.
Mortgage term is the length of your current rate agreement with the lender. Terms typically range from 1 to 5 years. When the term ends, you renew or refinance the remaining balance at a new rate.
A longer amortization period lowers your monthly payment but increases total interest paid. A shorter amortization does the opposite: higher payments, less interest overall. Use the calculator to test different amortization periods and see the tradeoff clearly.
Type of Mortgage and Payment Options
Choosing a type of mortgage goes beyond fixed or variable. You also decide between open and closed.
- Closed mortgage: Lower interest rate, but limits on how much extra you can prepay each year without penalty. Best if you plan to keep the mortgage for the full term.
- Open mortgage: Higher interest rate, but you can repay any amount at any time without penalty. Useful if you expect a large lump sum or plan to sell soon.
Most Canadians choose a closed mortgage with a fixed rate for payment stability. The right choice depends on your financial situation and how much flexibility you need.
Payment frequency for your monthly mortgage
Payment frequency controls how often you make a regular payment and how quickly you pay down the mortgage principal.
Common options include:
- Monthly: 12 payments a year
- Biweekly: 26 payments a year (every two weeks)
- Accelerated biweekly: 26 payments a year, but each payment equals half the monthly amount, which means you effectively make one extra monthly payment per year
- Weekly and accelerated weekly: Same concept, split into weekly intervals
Switching from monthly to accelerated biweekly can shave years off your amortization and save significant total interest. The calculator lets you toggle payment frequency to see exactly how each option changes your schedule.
Insurance coverage
Two types of insurance come up during the mortgage process.
Mortgage default insurance (sometimes called mortgage loan insurance) is required when your down payment is less than 20%. It protects the lender, not you, if you stop making payments. The premium is calculated as a percentage of the mortgage amount and is usually added to your mortgage principal. Providers include CMHC, Sagen, and Canada Guaranty.
Creditor insurance coverage (mortgage life or disability insurance) is optional. It helps protect you and your family by covering payments if you become ill, injured, or pass away. Your lender may offer this, but you can also shop for independent coverage.
This calculator can include the mortgage default insurance premium in your estimate when your down payment is below 20%.
Interest Paid Over the Life of Your Mortgage
One of the most useful outputs of this calculator is the total interest paid over the full amortization period. This number often surprises people.
For example, a $400,000 mortgage at 5.5% over 25 years results in roughly $280,000 in total interest. That is nearly 70% of the original mortgage amount paid in interest alone.
The calculator shows this figure so you can see the real cost of borrowing. Even small changes (a lower interest rate, a shorter amortization, or accelerated payments) can reduce total interest by tens of thousands of dollars.
These figures are estimates. Actual totals depend on rate changes at renewal, prepayments, and your specific mortgage contract terms.
Explore Your Mortgage Options
This calculator is a starting point for exploring your mortgage options. Try different scenarios:
- Compare a fixed rate versus a variable rate at today's quoted rates
- See how a 20-year amortization compares to a 25-year amortization
- Check whether accelerated biweekly payments fit your budget
- Test different purchase prices to find a comfortable range
Each scenario gives you a clearer picture before you speak with a lender or get pre-approved.
Prepayment options to pay your mortgage faster
Making prepayments is one of the most effective ways to pay your mortgage off sooner. Most closed mortgages allow annual lump-sum prepayments (often 10% to 20% of the original principal) and the option to increase your regular payment amount.
Common prepayment strategies:
- Annual lump sum: Apply a bonus, tax refund, or savings directly to the principal
- Increased regular payment: Bump your payment by a set percentage each year
- Accelerated payment frequency: Switch from monthly to accelerated biweekly or weekly
All extra money goes straight to mortgage principal, which reduces the balance that accrues interest. Over time, this can save you years and thousands of dollars in interest.
Check your mortgage contract for prepayment limits. Exceeding them on a closed mortgage usually triggers a penalty.
Purchase Price, Mortgage Amount, and How the Calculator Works
The calculator uses standard Canadian mortgage math. Here is how the key inputs connect:
- Mortgage amount = Purchase price minus down payment, plus mortgage default insurance premium (if applicable)
- Interest calculation: Canadian fixed-rate mortgages compound semi-annually, not monthly. The calculator converts the annual rate to an equivalent monthly rate using this standard.
- Payment calculation: The tool applies the amortization formula to determine each regular payment, then builds a payment schedule showing principal and interest portions.
What information do you need to use the calculator?
- Purchase price
- Down payment (dollar amount or percentage)
- Interest rate
- Amortization period
- Payment frequency
- Mortgage type (fixed or variable, for your own reference)
The result is an estimate. It does not account for property taxes, home insurance, legal fees, or other closing costs. Use it as a planning tool to narrow your search, then confirm numbers with a lender.

Frequently Asked Questions
How does a Canadian mortgage calculator estimate my mortgage payment?
It takes your purchase price, down payment, interest rate, and amortization period, then applies the standard Canadian mortgage formula. Canadian fixed-rate mortgages use semi-annual compounding, which the calculator converts to your chosen payment frequency. The result is an estimated regular payment amount.
What is the amortization period in a Canadian mortgage?
The amortization period is the total number of years it takes to repay the mortgage in full. Most Canadians choose 25 years. If your down payment is under 20%, the maximum insured amortization is 25 years. With 20% or more down, you may be able to amortize over 30 years, depending on the lender.
How do Canadian mortgage rates affect my payment?
A higher interest rate increases every payment and the total interest paid over the life of the mortgage. A lower interest rate does the opposite. Even a fraction of a percent matters over a 25-year amortization. Use the calculator to compare rates and see the dollar difference.
How does purchase price change my monthly payment?
A higher purchase price means a larger mortgage amount, which raises your monthly payment. It may also push your down payment below the 20% threshold, triggering mortgage default insurance. Test different purchase prices in the calculator to find a comfortable monthly payment.
What type of mortgage is right for me?
It depends on your priorities. A fixed rate mortgage gives predictable payments. A variable rate mortgage may start lower but can change. A closed mortgage offers a lower rate with prepayment limits. An open mortgage gives flexibility to repay anytime but at a higher rate. Most Canadians choose a closed, fixed rate mortgage for stability.
Do I need insurance coverage on my mortgage?
If your down payment is less than 20% of the purchase price, mortgage default insurance is mandatory in Canada. The premium is based on your loan-to-value ratio and is typically added to the mortgage principal. Optional creditor insurance coverage is a separate product that protects you or your family if you cannot make payments due to illness, injury, or death.
How can I pay my mortgage off sooner?
Three practical strategies:
- Switch to an accelerated biweekly or weekly payment frequency
- Make annual lump-sum prepayments when you have extra funds
- Increase your regular payment amount each year
All prepayments go directly to principal, reducing the balance that accrues interest. Check your mortgage contract for prepayment limits to avoid penalties.
What payment options does this mortgage payment calculator support?
The calculator supports monthly, semi-monthly, biweekly, accelerated biweekly, weekly, and accelerated weekly payment frequencies. It also lets you adjust the purchase price, down payment, interest rate, and amortization period. You can test different combinations to find the payment schedule that fits your budget.
