Canadian Mortgage Calculator
Free Canadian mortgage calculator with semi-annual compounding. Estimate monthly payments, total interest, and 25-year amortization schedule for home buyers.
About This Calculator
The Canadian Mortgage Calculator helps home buyers and homeowners estimate their monthly mortgage payments using the Canadian standard of semi-annual interest compounding. Unlike US mortgages where interest compounds monthly, Canadian law requires mortgage interest to compound semi-annually, which produces a slightly different effective rate. This calculator is designed specifically for Canadian residents and uses the Canadian dollar (CAD) as currency.
Our calculator uses the standard amortization formula: M = P × r × (1+r)^n / ((1+r)^n - 1), where P is the loan amount (home price minus down payment), r is the effective monthly interest rate derived from the semi-annually compounded annual rate, and n is the total number of monthly payments. The effective monthly rate is calculated as (1 + annualRate/2)^(2/12) - 1. The result includes monthly payment, total interest paid over the full amortization period, total payments, and a yearly amortization schedule showing principal and interest breakdown for each year.
How Canadian Mortgages Work
In Canada, most mortgages have two key timeframes: the term (typically 1 to 5 years) and the amortization period (typically 25 years). The term is the length of time your current mortgage contract and interest rate are locked in. At the end of each term, you negotiate a new rate with your lender or switch lenders. The amortization period is the total time it would take to fully repay the mortgage assuming you renew at each term end.
The minimum down payment in Canada is regulated: 5% for homes under $500,000, 10% on the portion between $500,000 and $999,999, and 20% for homes $1 million and above. If your down payment is less than 20%, you must purchase CMHC mortgage insurance, which protects the lender and is added to your mortgage principal. Higher down payments reduce the loan amount and may qualify you for better interest rates.
Canadian homeowners often accelerate their mortgage payments through bi-weekly or accelerated bi-weekly schedules, which can shave years off the amortization period and save tens of thousands in interest. Prepayment privileges of 10-20% of the original principal per year are common in Canadian mortgage contracts.
Frequently Asked Questions
How does a Canadian mortgage calculator differ from a US mortgage calculator?
Canadian mortgage rates compound semi-annually, while US rates compound monthly. This means a 5% Canadian rate has a slightly higher effective annual cost. Our calculator uses the semi-annual compounding formula required for Canadian mortgages.
What is the minimum down payment for a home in Canada?
In Canada, the minimum down payment is 5% for homes up to $500,000, 10% for the portion between $500,000 and $999,999, and 20% for homes $1 million or more. Down payments under 20% require CMHC mortgage insurance.
What amortization period should I choose for my Canadian mortgage?
The standard amortization period for Canadian mortgages is 25 years. Insured mortgages (down payment under 20%) allow up to 25 years, while uninsured mortgages can extend to 30 years. A shorter amortization means higher monthly payments but less total interest.
How often is mortgage interest compounded in Canada?
In Canada, mortgage interest is legally required to compound semi-annually, not monthly. This is set by the Canadian Interest Act. Our calculator automatically applies semi-annual compounding to give accurate payment estimates.
Can I pay off my Canadian mortgage early?
Most Canadian mortgages allow prepayment privileges of 10-20% of the original principal per year without penalty. Many lenders also allow increasing monthly payments by 10-20% annually. Check your mortgage contract for specific terms.
What is the difference between mortgage term and amortization period in Canada?
The amortization period is the total time to fully pay off the mortgage (typically 25 years). The term is the length of your current mortgage contract (usually 1-5 years). At the end of each term, you renew with a new rate and terms.
Does CMHC insurance affect my mortgage payment calculation?
CMHC insurance premiums range from 0.6% to 4.0% of the loan amount and are added to the mortgage principal when the down payment is less than 20%. This increases the total loan amount and monthly payments accordingly.
