Pros and Cons of Extending Amortization

Feeling the renewal squeeze? Let’s talk amortization

If your mortgage is up for renewal soon, you’re in good company. One strategy Canadians are leaning on: extending their amortization period.

Amortization refers to the period of time in years that a borrower will take to repay the loan in full. When borrower enters his initial mortgage, the amortization is generally set for 25 years but it can be extended or reduced based on some criteria. The maximum amortization period is 40 years and the smallest is essentially zero when a mortgage is fully repaid.

That’s a fancy way of saying stretching your mortgage out over more years to make monthly payments smaller.


During the term of the mortgage multiples factors influences the amortization period:

  • The payment frequency has the biggest impact on the amortization. The more frequent the borrower makes a payment, the shorter the amortization will become because the principal will be repaid faster.
  • Making additional payments over the pre-scheduled mortgage payment where the full amount goes against the principal will also significantly reduce the amortization period.
  • Longer amortization period will result in lower payment over the duration of the mortgage but the consequence is that more interest will be paid. This option is good for people with limited income and tight budget or the borrower prefers to keep funds as safety.

It’s important to point out that extending the amortization over 25 years could result in a small rate premium by the lender to compensate for additional risk. On the other hand, a shorter amortization period will result in higher payment and be mortgage free sooner, this can leave the borrower without excess funds should an emergency occurs. As mentioned above the payment frequency will have the most significant impact on the amortization. The higher the payment frequency, the faster the principal will be repaid and shorter the amortization will be.

Here’s the trade-off in plain terms:

Pros and Cons of Extending Your Amortization

Pro
Lower monthly payments = more breathing room in your budget

Con
You’ll pay more interest over time (and yes, that adds up)

Here’s a quick comparison for a $900,000 mortgage at a 3.84% fixed rate:

comparing a 25-year vs. a 30-year amortization on a $900K mortgage at. fixed rate
Amortization PeriodMonthly PaymentTotal Interest Paid
25 years$4,656$496,681
30 years$4,221$619,490

Difference:

  • Monthly savings by extending to 30 years: ≈ $435/month
  • Additional interest cost over the life of the mortgage: ≈ $122,809

But if renewal rates are higher than your current rate, extending your amortization might be the life raft that keeps your finances afloat instead of watching your payments climb faster than grocery prices.

Amortization Example

For example:

Property value $1,000,000

Downpayment: $200,000

Mortgage amount: $800,000

Rate: 4.25%

Payment FrequencyAmountAmortization PeriodTotal Interest Cost
Monthly (12) $4,317.2825 years$495,184.39
Semi-monthly (24) $2,157.5724 years, 11 months$494,544.12
Bi-weekly (26) $1,991.5324 years, 11 months$494,494.85
Accelerated bi-weekly (26) $2,158.6421 years, 10 months$422,624.64
Accelerated weekly (52) $1,079.32 21 years, 10 months $421,813.93




Monthly:

This is the most common payment schedule. You’ll make 12 payments a year, once a month, resulting in the most interest paid and taking the longest amount of time
of all the options.

Semi-monthly:

With a semi-monthly payment plan, you’ll make payments twice a month, resulting in 24 payments a year. This schedule will reduce your amortization period by about one month.

Bi-weekly:

Bi-weekly payments are made once every two weeks, resulting in 26 payments a year. Similar to a semi-monthly payment schedule, your amortization is reduced by a month.

Accelerated bi-weekly:

With an accelerated bi-weekly payment schedule, you take your monthly payment, divide it by two, and make that payment every two weeks. This results in an extra monthly payment each year compared to a regular bi-weekly payment schedule. This helps to reduce the principal balance more quickly.

Accelerated weekly:

An accelerated weekly payment schedule involves dividing your monthly mortgage payment by four and making that payment every week, resulting in 52 payments per year. This method effectively adds an extra monthly payment annually, reducing the principal balance more quickly.

P.S. There’s a difference between choosing to extend your amortization and hitting your trigger rate (when your payments only cover interest). If you’re unsure where you stand, we can help.

Reminder: Don’t just auto-renew.
