Buying a home in Canada involves more than deciding how much you can borrow. Your down payment affects the size of your mortgage and whether you need mortgage default insurance. The interest rate influences your regular payment, while the amortization period determines how long you have to pay off the loan. You also need to understand what happens when your mortgage term ends and your lender offers a renewal.
Use this Canadian mortgage calculator to estimate your mortgage payments in Canadian dollars (CAD), compare different down payments and interest rates, and see how mortgage default insurance may affect the amount you borrow. You can also compare accelerated bi-weekly payments to understand how a different payment schedule could help you reduce your mortgage balance faster.
The results are estimates based on your inputs. Your lender’s actual payment, insurance premium and mortgage conditions may differ.
Start With the Home Price and Down Payment
The amount you borrow is not necessarily the same as the price of the home. Your down payment covers part of the purchase price, and the mortgage covers the remaining amount. If you need mortgage default insurance, the premium may also be added to the mortgage balance.
Suppose you are considering a home priced at $600,000 and have saved $60,000 for the down payment.
| Purchase detail |
Amount |
| Home price |
$600,000 |
| Down payment |
$60,000 |
| Down payment percentage |
10% |
| Mortgage before insurance |
$540,000 |
You would initially need to borrow $540,000. Because your down payment is below 20%, mortgage default insurance will generally be required if the purchase qualifies for an insured mortgage. If the premium is added to the loan, your final mortgage balance will be higher than $540,000.
To use the calculator, enter the purchase price, down payment, annual interest rate and amortization period. Compare the results with different inputs instead of relying on a single estimate. For example, you could test whether increasing your down payment from $60,000 to $90,000 makes a meaningful difference to the monthly payment and insurance cost.
How Much Down Payment Do You Need in Canada?
Canada’s minimum down payment rules depend on the purchase price. You do not always need to put down the same percentage of the entire property value.
| Purchase price |
General minimum down payment |
| $500,000 or less |
5% of the purchase price |
| More than $500,000 and less than $1.5 million |
5% of the first $500,000, plus 10% of the portion above $500,000 |
| $1.5 million or more |
20% of the purchase price |
These are the general minimums for eligible purchases. Lenders may require a larger down payment depending on the borrower’s circumstances and the property. See the Government of Canada’s down payment guidance for the applicable rules.
Example: buying a $600,000 home
If you are buying a $600,000 property, the minimum down payment is calculated in two parts:
-
First $500,000 × 5% = $25,000
-
Remaining $100,000 × 10% = $10,000
-
Minimum down payment = $35,000
That is approximately 5.83% of the purchase price. It is not 5% of the entire $600,000.
A smaller down payment can help you buy sooner, but it usually means a larger mortgage and mortgage default insurance costs. A larger down payment reduces the amount borrowed and may allow you to avoid that insurance if you meet the relevant requirements.
Do not use your entire savings balance for the down payment without accounting for closing costs. Legal fees, a home inspection, moving expenses, property taxes and other purchase-related costs may need to be paid separately.
When Do You Need Mortgage Default Insurance in Canada?
Mortgage default insurance is an important part of Canadian home financing, particularly for buyers who have saved less than 20% of a property’s purchase price.
If your down payment is below 20%, you will generally need mortgage default insurance when the property and mortgage meet the eligibility rules. The insurance protects the lender if the borrower defaults; it does not protect you against missed payments or remove your responsibility to repay the mortgage.
CMHC is one provider of mortgage loan insurance. Other providers include Sagen and Canada Guaranty.
The premium depends on factors such as your loan-to-value ratio and the applicable premium schedule. You may be able to pay the premium upfront or add it to your mortgage. If it is financed, you also pay interest on that amount over time. In Ontario, Manitoba and Quebec, provincial sales tax may apply to the insurance premium and generally must be paid separately rather than added to the mortgage.
Example: a $500,000 home with a $50,000 down payment
The initial mortgage amount is:
$500,000 − $50,000 = $450,000
That is a 90% loan-to-value ratio. If mortgage default insurance is required and the premium is financed, the mortgage balance used to calculate repayments will be higher than $450,000.
This distinction matters when comparing calculator results. Check whether the displayed mortgage amount includes the insurance premium, and do not compare an insured mortgage payment with an uninsured mortgage payment without checking that both use the same assumptions.
You can review the CMHC mortgage loan insurance information to understand eligibility and premiums. Insurance eligibility rules and rates can change, so use the current premium schedule for a final estimate.
Mortgage Payment Example: A $500,000 Canadian Home
Imagine you are buying a home for $500,000, have saved $50,000 and are considering a mortgage with a 5% annual interest rate and a 25-year amortization period.
| Mortgage detail |
Example |
| Purchase price |
$500,000 |
| Down payment |
$50,000 |
| Down payment percentage |
10% |
| Mortgage before insurance |
$450,000 |
| Assumed annual interest rate |
5% |
| Amortization period |
25 years |
Because the down payment is 10%, mortgage default insurance will generally be required if the purchase qualifies for an insured mortgage. The insurance premium may be added to the balance, which increases the amount used to calculate your payments.
To understand the result, work through the figures in this order:
-
Subtract the down payment from the home price to calculate the mortgage before insurance.
-
Determine whether mortgage default insurance applies.
-
Calculate the premium using the relevant insurer’s current rules.
-
Add the premium to the mortgage balance if it is financed.
-
Use the annual rate, Canadian interest-compounding convention and amortization period to estimate the regular payment.
The final monthly payment depends on whether insurance is included, the rate conversion used, and the payment schedule selected. Enter these details into the calculator to see the estimate generated by the tool.
This is also a useful scenario for comparing a 10% down payment with a 20% down payment. The latter would require $100,000 upfront, but would generally avoid mortgage default insurance on an otherwise eligible conventional mortgage. The decision involves balancing the upfront cash required against the size and cost of the mortgage.
Why Canadian Mortgage Interest Is Compounded Semi-Annually
A Canadian fixed mortgage rate is commonly quoted using semi-annual compounding. That convention can make a Canadian mortgage calculation different from one that simply divides the annual rate by 12.
For a quoted annual rate (r), expressed as a decimal, the equivalent monthly rate under semi-annual compounding is:
[
i=\left(1+\frac{r}{2}\right)^{1/6}-1
]
Here, (i) represents the monthly rate used in the payment calculation. For example, an annual rate of 5% is entered as 0.05 in the formula.
This conversion matters because the monthly payment depends on the interest rate applied to the outstanding balance. If two calculators use different rate-conversion assumptions, their results may not match exactly even when the displayed annual rate is the same.
Semi-annual compounding does not mean you make mortgage payments only twice a year. Depending on your mortgage agreement, payments may be monthly, semi-monthly, bi-weekly, accelerated bi-weekly or weekly.
The actual calculation can also depend on whether the mortgage has a fixed or variable rate and on the lender’s contractual terms. Use the rate and payment settings that correspond to the mortgage you want to compare.
Mortgage Term vs. Amortization Period in Canada
These two terms sound similar, but they describe different parts of your mortgage.
Amortization period is the total time scheduled to repay the mortgage in full, such as 25 or 30 years.
Mortgage term is the period during which your current mortgage contract and its conditions apply. Terms are often much shorter than the amortization period, and the mortgage generally needs to be renewed or otherwise dealt with when the term ends.
For example, you might take out a mortgage with a 25-year amortization and a five-year fixed term. After five years, you would normally still owe a substantial amount. The five-year term is ending; the entire 25-year repayment schedule is not.
At renewal, the interest rate and payment may change depending on the mortgage product you choose and the rates available at that time. If you simply project today’s rate across the full 25 years, you are estimating what would happen if that rate remained unchanged—not predicting the rates you will actually receive at future renewals.
When comparing mortgage offers, consider both the current term and the amortization period. A low introductory payment may not tell you what the mortgage will cost over its full life.
Could Accelerated Bi-Weekly Payments Help You Pay Off Your Mortgage Faster?
Payment frequency affects how much you pay over a year. With a standard monthly schedule, you make 12 payments annually. With accelerated bi-weekly payments, you typically pay half the monthly amount every two weeks, resulting in 26 payments a year.
For example, if your regular monthly mortgage payment is $2,000:
| Payment schedule |
Payment amount |
Payments per year |
Annual total |
| Monthly |
$2,000 |
12 |
$24,000 |
| Standard bi-weekly |
About $923.08 |
26 |
$24,000 |
| Accelerated bi-weekly |
$1,000 |
26 |
$26,000 |
The accelerated schedule adds the equivalent of one extra monthly payment each year. When those additional amounts are applied to the mortgage as intended, they can reduce the principal faster and lower the interest paid over time.
The benefit comes with a budgeting trade-off. Accelerated bi-weekly payments require more cash over the year than standard monthly or standard bi-weekly payments. Make sure the higher payment fits your income schedule and leaves enough room for other expenses.
The exact savings depend on your balance, rate, remaining amortization, payment dates and lender’s rules for applying extra payments. Use the calculator’s accelerated bi-weekly result to compare the regular payment with the accelerated schedule, and confirm the details with your lender before changing your payment arrangement.
Will You Qualify for the Mortgage? Understanding Canada’s Stress Test
A mortgage payment calculator estimates the cost of a loan. It does not decide whether a lender will approve you for that amount.
Federally regulated lenders generally apply a mortgage stress test to assess whether you could manage payments at a qualifying interest rate. The qualifying rate is generally the higher of 5.25% or your contracted mortgage rate plus two percentage points, subject to the rules that apply to your application.
For example, if a lender offers a contract rate of 4.5%, the qualifying rate under this general rule would be 6.5%. That does not mean your actual mortgage payment will be charged at 6.5%; the higher rate is used for the qualifying assessment.
Lenders also consider your income, existing debts, credit history and other housing costs. Property taxes, heating costs and applicable condominium fees can affect the assessment of how much you can afford.
Use this calculator to estimate repayments at the rate you expect to pay. If you want to estimate how much a lender might allow you to borrow, use a mortgage affordability or mortgage qualifier calculator as a separate step. Read the Government of Canada’s mortgage qualification guidance for more information.
What Will Your Home Cost Beyond the Mortgage Payment?
Your monthly mortgage payment is only one part of the cost of owning a home in Canada. The total housing budget depends on the property, the municipality and your household’s needs.
Before deciding whether a home is affordable, consider these expenses:
-
Property taxes: Municipal rates and assessed values affect the amount you pay. Some lenders collect property taxes with mortgage payments, while others leave you to pay the municipality directly.
-
Home insurance: The cost depends on the property, coverage and insurer.
-
Utilities: Heating, electricity, water and other services can vary significantly by property and location.
-
Condominium fees: If you are buying a condo, monthly fees can make a meaningful difference to the total housing cost.
-
Maintenance and repairs: Budget for routine upkeep and unexpected problems, particularly if the property is older.
-
Closing costs: Legal fees, inspection costs and applicable provincial or municipal land transfer taxes may be due around closing.
-
Moving expenses and furnishings: These can add to the cash needed immediately after purchase.
Consider a condo with a lower mortgage payment but substantial monthly fees. Its total housing cost may be higher than that of a house with a slightly larger mortgage payment. Comparing only the mortgage figure would miss that difference.
Before making an offer, add the estimated mortgage payment to your other monthly housing expenses and existing debt payments. The remaining amount should leave enough room for everyday spending, savings and unexpected costs.
Compare Mortgage Payments at Different Interest Rates
The rate you enter can make a meaningful difference to the payment. If you are comparing lender offers or preparing for a future renewal, test more than one rate while keeping the purchase price, down payment, amortization and payment frequency unchanged.
For example, use the same $500,000 home and $50,000 down payment, then compare the calculator’s results at 4%, 5% and 6%. Keep the mortgage insurance assumptions consistent across all three scenarios so the comparison shows the effect of the interest rate rather than a change in the loan balance.
A higher rate generally increases the required payment on a repayment mortgage. It also affects the interest charged over time. A lower rate reduces the payment under the same assumptions, but the actual offer you receive will depend on the lender, mortgage type, term and your eligibility.
Do not treat this exercise as a forecast of future interest rates. A fixed mortgage rate normally applies for the agreed term, not necessarily the entire amortization period. At renewal, the rate may be higher or lower.
If the payment becomes uncomfortable at a slightly higher rate, that is useful information to have before committing to the purchase. It can help you decide whether to increase your down payment, consider a lower-priced home or leave more room in your budget.
How We Calculate Canadian Mortgage Payments
The calculator starts with the purchase price and subtracts the down payment to estimate the amount borrowed. Where applicable, it estimates mortgage default insurance and may include the premium in the mortgage balance.
For a standard repayment mortgage, the payment is based on the amount borrowed, the applicable periodic interest rate and the number of scheduled payments over the amortization period. For Canadian fixed-rate mortgage calculations, the rate conversion commonly reflects semi-annual compounding.
The standard payment formula is:
[
M=P\frac{i(1+i)^n}{(1+i)^n-1}
]
Where:
-
(M) is the scheduled payment per period.
-
(P) is the mortgage principal used in the calculation.
-
(i) is the interest rate per payment period.
-
(n) is the total number of scheduled payments.
The formula is applied using the payment frequency and rate-conversion assumptions supported by the calculator. Accelerated bi-weekly payments are typically calculated as half the monthly payment every two weeks.
The results are estimates rather than lender quotes. They may differ from an actual mortgage illustration because of insurance eligibility, fees, payment dates, variable-rate terms and lender-specific calculations. The calculator also does not assess your income, credit history or eligibility for a mortgage.
