YOUR ESTIMATE
💡 Did you know? Mortgage life insurance pays off your mortgage in the event of your death. Save up to 50% by using an independent broker instead of your lender.
Broker’s advice
Before you sign your mortgage, compare individual life insurance to your lender. Independent life insurance is often 30-50% cheaper, owned by you (transferable if you switch banks), and coverage remains fixed instead of decreasing with the balance of the loan.
How does the mortgage payment calculation work?
The periodic payment of a mortgage is calculated according to a standard mathematical formula that spreads the principal and interest over the entire amortization period. Here are the key things to understand.
STANDARD FORMULA
M = P × r(1 + r)n ⁄ (1 + r)n − 1
where M = periodic payment, P = borrowed capital, r = periodic rate, n = total number of payments
Interest rates
The higher the rate, the higher the payment. A 0.5% change over 25 years can add up to more than $25,000 in interest.
Payback period
A longer period (30 years) reduces the monthly payment but greatly increases the total cost of interest paid.
Down payment
A down payment of 20% or more avoids CMHC loan insurance and reduces your monthly payment.
Examples of payments by scenario

| $200,0005.25 | % | 25 years | $1,192 | $157,581 |

| $500,0005.25 | % | 25 years | $2,980 | $393,953 |
| $300,0005.25 | % | 15 years | $2,410 | $133,758 |
| $300,0005.25 | % | 30 years | $1,656 | $296,235 |

5 steps to using the calculator properly
Estimate the price of the property
Indicate the total amount of your purchase (before transfer taxes, notary fees and inspection).
Enter your down payment
In Quebec, the minimum is 5% on the first $500,000 and 10% on the portion between $500,001 and $1 million.
Choose a realistic interest rate
Look at the Bank of Canada’s posted rates and add the banks’ usual margin (1.5 to 2 per cent).
Select the amortization period
25 years is the norm. 30 years is possible with a down payment of 20% or more, but costs more in interest.
Compare payment frequencies
An accelerated bi-weekly payment can save 3 to 5 years of amortization and tens of thousands in interest.
