Mortgage Payment Frequency: Weekly vs Monthly Payments

The Small Choice That Shaves Years Off Your Mortgage

When you set up a mortgage, your lender asks how often you want to make payments. It sounds like a trivial scheduling question, but the option you pick can quietly save you thousands of dollars and shorten your amortization by years. The magic word to watch for is accelerated.

Your Payment Frequency Options

Canadian lenders typically offer several schedules. Here's how they relate to one another:

Notice the difference in the last column. With non-accelerated schedules, your annual total is exactly the same as paying monthly — the lender just slices the year's 12 payments into smaller pieces. With accelerated schedules, the lender takes your full monthly payment and simply charges half of it every two weeks (or a quarter of it every week).

How "Accelerated" Sneaks In a Free Extra Payment

Here's the trick. A month is a little longer than four weeks, so there are 26 bi-weekly periods in a year, not 24. If you pay half your monthly amount 26 times, you make the equivalent of 13 monthly payments a year instead of 12.

That one extra payment goes straight against your principal. Because it reduces the balance that interest is charged on, the savings compound over the life of the mortgage — you pay down the loan faster, which means less interest, which pays it down faster still.

An Illustrative Example

Consider a simple, rounded example (for illustration only — not a quote). Say your monthly payment is 2,000 dollars on a 25-year amortization.

• Monthly: 12 payments a year = 24,000 dollars annually. You finish in 25 years.
• Accelerated bi-weekly: 1,000 dollars every two weeks, 26 times a year = 26,000 dollars annually.

That's an extra 2,000 dollars toward principal each year without ever writing a separate cheque. On a typical mortgage, switching to accelerated bi-weekly can trim roughly three to four years off a 25-year amortization and save a substantial amount of interest over the full term. The larger your mortgage and the higher your rate, the bigger the effect.

Choosing the Right Schedule

• Want maximum savings? Choose an accelerated frequency (accelerated bi-weekly is the most popular). You're effectively making that 13th payment painlessly.
• Want to match your paycheque? Line your payments up with your pay periods so the money leaves right after it arrives. Many people are paid bi-weekly, which makes accelerated bi-weekly a natural fit.
• Budget is tight? A non-accelerated bi-weekly or semi-monthly schedule keeps your annual total identical to monthly while smoothing cash flow — no extra cost, just easier budgeting.

One caution: confirm you're actually getting the accelerated option. Plain bi-weekly and accelerated bi-weekly look almost identical on paper, but only the accelerated version produces the extra annual payment and the faster payoff.

The Bottom Line

Payment frequency is one of the easiest wins in personal finance: no refinancing, no rate change, just a smarter schedule. If your cash flow can absorb it, an accelerated frequency puts you on track to be mortgage-free sooner and keeps more interest in your pocket.
