Free Mortgage Payment Calculator - Calculate Monthly Payments, CMHC & Stress Test
A mortgage is a loan used to purchase a home, where the property serves as collateral. Monthly payments are calculated using the loan amount, interest rate, and amortization period. In Canada, mortgage payments typically include principal, interest, and may include property taxes and insurance (PITI). For example, a $400,000 mortgage at 5.25% over 25 years results in approximately $2,403 monthly payment.
This calculator uses the Canadian mortgage payment formula M = P[r(1+r)^n]/[(1+r)^n - 1] with semi-annual compounding per the Bank Act, as required by federal regulations.
This Mortgage Calculator is designed specifically for Canadian mortgages and includes CMHC insurance calculations, federal stress test requirements, and provincial land transfer taxes. All calculations follow Office of the Superintendent of Financial Institutions (OSFI) guidelines and Bank of Canada standards.

A mortgage is likely the largest financial commitment you'll make. Understanding how mortgages work in Canada, including CMHC insurance requirements, the mortgage stress test, and payment options, will help you make informed decisions and potentially save thousands of dollars.
If your down payment is less than 20% of the home's purchase price, you must purchase mortgage default insurance from CMHC, Sagen, or Canada Guaranty. Insurance premiums range from 2.8% to 4% of the mortgage amount depending on your down payment size. This insurance protects the lender if you default on your mortgage.
Canadian lenders must qualify you at either your contracted rate plus 2% or 5.25%, whichever is higher. This ensures you can still afford your mortgage if rates increase. Our calculator shows both your actual payment and the stress test payment lenders will use to qualify you.
Accelerated bi-weekly or weekly payments can significantly reduce your amortization period and total interest paid. With accelerated payments, you make the equivalent of one extra monthly payment per year, helping you pay off your mortgage faster.
Input the purchase price of the property and your planned down payment amount. If your down payment is less than 20%, CMHC mortgage insurance will be calculated automatically.
Enter the annual mortgage interest rate and select your amortization period. The calculator uses semi-annual compounding as required by Canadian federal regulations under the Bank Act.
Select your province to calculate land transfer tax, and choose your preferred payment frequency. Accelerated bi-weekly or weekly options can save thousands in interest over the life of your mortgage.
Review your payment amount, total interest, CMHC insurance costs, stress test qualification, and upfront costs including land transfer tax and estimated closing costs.
A minimum 5% down payment is required for homes under $500,000. For homes between $500,000 and $1 million, you need 5% on the first $500,000 and 10% on the remainder. Homes over $1 million require a 20% down payment. A larger down payment reduces your mortgage amount and can help you avoid CMHC insurance costs.
Your mortgage interest rate has the biggest impact on your total cost. Even a 0.25% rate difference can save you thousands over your amortization period. Shop around with multiple lenders and consider both fixed and variable rate options. Fixed rates provide payment stability, while variable rates may offer savings if rates decrease.
The amortization period is the total time it takes to pay off your mortgage. In Canada, the maximum is typically 25 years for insured mortgages (under 20% down) and 30 years for uninsured mortgages. Shorter amortization periods mean higher payments but significantly less interest paid over time.
Choosing accelerated bi-weekly or weekly payments instead of monthly payments can help you pay off your mortgage years earlier and save thousands in interest. With accelerated payments, you make the equivalent of 13 monthly payments per year instead of 12.
Results are estimates based on the information provided. Actual mortgage terms, rates, and approval depend on your credit score, employment history, debt ratios, and individual lender policies.
The rate you enter may differ from the rate a lender offers you. Rates change frequently based on Bank of Canada decisions, bond markets, and lender competition. Get a pre-approval for your actual rate.
Estimated closing costs are based on provincial averages. Actual legal fees, inspection costs, title insurance, and other expenses vary by location, property type, and your specific circumstances.
This calculator focuses on mortgage payments. Budget separately for property taxes, home insurance, utilities, condo fees, maintenance (typically 1-2% of home value annually), and moving costs.
Mortgage pre-approval shows sellers you're serious and helps you understand your true budget. It locks in your rate for 90-120 days and strengthens your offer in competitive markets.
Aim for 20% down to avoid CMHC insurance (2.8-4% of mortgage). On a $500,000 home, 20% down saves $11,200-16,000 in insurance premiums plus lower monthly payments.
Accelerated bi-weekly payments make an extra month's payment per year automatically. On a $400,000 mortgage at 5%, this saves $34,000 in interest and pays off your mortgage 3 years faster.
Even 0.25% rate difference matters significantly. On a $400,000 mortgage, 0.25% lower rate saves $12,500 over 25 years. Use a mortgage broker to compare offers from multiple lenders.
Beyond down payment, budget for land transfer tax (1-2% of price), legal fees ($1,000-2,000), home inspection ($400-600), and moving costs. First-time buyers should budget 5-7% of purchase price for total upfront costs.
Reducing from 25 to 20 years increases payments slightly but saves enormous interest. On a $400,000 mortgage at 5%, 20-year amortization saves $65,000 in interest despite only $250/month higher payments.
Just because you're approved for $600,000 doesn't mean you should borrow it. Lenders approve based on gross income, but you live on net income. Leave room in your budget for maintenance, property taxes, and unexpected costs.
You must qualify at a higher rate (qualifying rate + 2% or 5.25%, whichever is higher), but you'll pay your actual rate. This buffer protects you if rates rise. Never push your budget to the maximum qualification.
A $500 home inspection can reveal $50,000 in hidden problems. Foundation issues, roof repairs, electrical problems, and mold can be deal-breakers. Always include a home inspection condition in your offer.
Your 5-year term is not your 25-year amortization. After 5 years, you'll need to renew at current rates which could be significantly different. Consider how rising rates would affect your budget before committing.
The total time it takes to fully pay off your mortgage. In Canada, maximum is 25 years for insured mortgages (under 20% down) and 30 years for conventional mortgages. Longer amortization means lower payments but much more interest paid.
The length of time your mortgage contract and interest rate are locked in, typically 1-5 years. At the end of each term, you renew your mortgage at current rates. This is different from your amortization period.
The upfront payment you make toward the home purchase. Minimum is 5% for homes under $500,000, 5-10% for $500K-$1M, and 20% for homes over $1M. Higher down payments mean lower monthly costs and no CMHC insurance.
Mortgage default insurance required when down payment is less than 20%. Premiums range from 2.8% to 4% of mortgage amount. This protects the lender (not you) if you default. Cost can be added to your mortgage.
Federal requirement that you qualify for a mortgage at a higher interest rate (your rate + 2% or 5.25%, whichever is higher). This ensures you can still afford payments if rates increase.
How often you make mortgage payments: monthly, bi-weekly, or weekly. Accelerated frequencies make extra payments per year, significantly reducing interest and amortization period.
Provincial tax on property transfers, typically 0.5-2.5% of purchase price depending on province and home value. First-time buyers may qualify for rebates. Toronto and Montreal have additional municipal taxes.
Additional costs beyond down payment including legal fees ($1,000-2,000), home inspection ($300-600), title insurance ($250-400), property appraisal ($300-500), and land transfer tax. Budget 1.5-4% of purchase price.
The actual amount you borrowed for your mortgage, not including interest. Each payment includes both principal (reduces your loan) and interest (cost of borrowing). Early payments are mostly interest, later payments are mostly principal.
The annual percentage rate you pay to borrow money. Canadian mortgages typically use semi-annual compounding. Even small rate differences (0.25%) can save tens of thousands over your amortization period.
Land transfer tax rates, first-time buyer rebates, and average home prices vary by province. Select your province for a tailored mortgage calculation.
