Mortgage Term vs. Amortization

One of the most common sources of confusion for prospective home buyers is the difference between a mortgage term and amortization period. Here is a short answer: A mortgage term is the length of your current contract, at the end of which you'll need to renew; The amoritization period is the total life of your mortgage. A typical mortgage in Canada has a 5-year term with a 25-year amortization period.

Mortgage term

The mortgage term is the length of time you commit to the mortgage rate, lender, and associated mortgage terms and conditions. The term you choose will have a direct effect on your mortgage rate, with short terms historically proven to be lower than long-term mortgage rates. The term acts like a 'reset' button on a mortgage. When the term is up, you must renew your mortgage on the remaining principal, at a new rate available at the end of the term.

Mortgage amortization period

The mortgage amortization period, on the other hand, is the length of time it will take you to pay off your entire mortgage. Over the course of your amoritization period, you'll sign multiple mortgage contracts. Most maximum amortization periods in Canada are 25 years. Longer amortization periods reduce your monthly payments, as you are paying your mortgage off over a greater number of years. However, you will pay more interest over the life of the mortgage.


Maximum amortization period

As of March 2020, the maximum amortization period on all CMHC insured homes is 25 years. This became low in June 2012, when the federal government announced the maximum amortization period on CMHC insured homes would be reduced from 30 to 25 years. CMHC insurance is required on all home purchases with a down payment of 20% or less. Therefore, if you are putting more than 20% down on your purchase, some lenders may accept an amortization period of greater than 30 years.

Prior to this, on March 18th 2011, the maximum amortization on CMHC insured mortgages was reduced from 35 to 30 years.


Short vs. long term amortization periods

Many home buyers choose shorter amortization periods resulting in higher monthly payments if they can afford to do so, knowing that it promotes positive saving behaviour and reduces the total interest payable. For example, let us consider a $300,000 mortgage, and compare a 25-year versus 30-year amortization period.

Scenario A
Shorter amortization
(25 years)
Scenario B
Longer amortization
(30 years)
(Scenario B-A)
Mortgage amount$300,000$300,000-
Amortization period25 years30 years-
Interest rate5.1%5.1%-
Monthly payment$1,762$1,620($142)
Total interest$228,580$339,659$111,079

The mortgage payments under scenario B are smaller each month, but the home owner will make monthly payments for 5 additional years. The total interest saved by going with a shorter amortization period exceeds $100,000.

For the savvy investor, these savings should be compared to the opportunity cost of other investments. Using the example above, the monthly savings of $142 under scenario B, could be invested elsewhere, and, depending on the rate of return, could come out ahead after 35 years.

Prepayment privileges set out by your lender will determine whether you can shorten your amortization period, by either increasing your regular monthly payments and/or putting lump sum payments towards the principal, without penalty. However, beyond these privileges, you will often incur costly penalties for making additional payments. According to the Canadian Association of Mortgage Professionals, 24% of Canadians took advantage of prepayment options in 2009.
