How Much Difference Will Extra Payments Make Towards My Mortgage?

Sabeena Bubber • May 7, 2019

Have you ever wondered how much difference extra payments actually make in paying down your mortgage? Let's take a look and maybe do a little math.

The first (and largest) factor to look at is the amortization, which is the remainder of your mortgage’s life. A majority of mortgages today start with 25-year amortizations. If you have made only regular payments for 5 years on a 25-year mortgage, your remaining amortization will be 20 years. Pretty simple, right?

Someone making an extra payment on a mortgage with 20 years left will save WAY more interest than someone making the same payment on a mortgage with 5 years left. The more years remaining on a mortgage, the more impact your extra payment will make.

The second factor to keep in mind is the mortgage interest rate. Your interest rate will change many times over the life of your mortgage, divided up by mortgage terms. If you agree to a 5-year term, you will only have that interest rate for 5 years, and then it will be time to renew at a different interest rate. At the time of this writing, mortgage rates are exceptionally low (even after some recent increases in 2018), and based on the last rate decision from the Bank of Canada on April 24/2019, they do not appear to be increasing anytime in 2019.

So what does that mean for you? Well, it depends if you are renewing this year, or 3 years from now. If you are renewing this year, you may want to consider your investment options for a lump sum amount, as opposed to paying down your mortgage. Paying down your mortgage makes the most sense when your amortization is high, and interest rates are also high (or going higher). If you’re renewing in three years time, then you may still want to consider paying down your mortgage, especially if you think mortgage rates will be higher at your renewal. The more you can pay when your mortgage is below 4%, the better payoff it will be if rates increase above 5%.

This is all conjecture and guesswork, especially when deciding between paying down your mortgage or investing more. However, mortgage rates have been abnormally low for a while now, and for whatever reason, the government of Canada selected a benchmark rate above 5% to qualify for a mortgage. Where interest rates go is anyone’s best guess, but it’s nice to be ahead of the game on your mortgage than trying to play catch-up with higher interest rates.

So let’s talk dollar amounts. For all of my examples, I’m going to use a $250,000 mortgage at 3.49% with 20 years remaining - that works out to a payment of $1445.40. If you switch to an accelerated bi-weekly, you’ll pay $722.70 every two weeks (half of the monthly amount), but you’ll save over $12,000 over the next 20 years because you will be making a couple of extra payments per year. Those payments really add up.

With the same mortgage (back on the regular monthly payment), let’s say you have $10,000 floating around your accounts, and you decide to use that money to pay down your mortgage. You’ll have saved around $9,500 in interest thanks to that payment. If you did BOTH the accelerated bi-weekly schedule and the $10,000 payment, it combines to over $20,000 of saved interest.

One more calculation with this mortgage - let’s say that, instead of any of the options described here, you decide to increase the monthly payment from $1445.40 to $1600 even. In just the 5 years time, you would save almost $6000 in interest over the life of the entire mortgage. But if mortgage rates stayed the same for the entire life of the mortgage, and you kept up the additional payment of only $154.60/month, you would pay off the mortgage 3.5 years sooner, AND save almost $15,000 in interest.

In summary, paying down your mortgage can feel good, both in your mind and in your wallet. It makes the most sense to pay down your mortgage when both amortization and interest rates are high. It can sometimes be difficult choosing between investing more and paying down your mortgage, but you can think of your mortgage interest rate as a guaranteed return, which is typically better than your GIC options.

Owning a home feels great—carrying a large mortgage, not so much. The good news? With the right strategies, you can shorten your amortization, save thousands in interest, and become mortgage-free sooner than you think. Here are four proven ways to make it happen: 1. Switch to Accelerated Payments One of the simplest ways to reduce your mortgage faster is by moving from monthly payments to accelerated bi-weekly payments . Instead of 12 monthly payments a year, you’ll make 26 half-payments. That works out to the equivalent of one extra monthly payment each year, shaving years off your mortgage—often without you noticing much difference in your budget. 2. Increase Your Regular Payments Most mortgages allow you to boost your regular payment by 10–25%. Some even let you double up payments occasionally. Every extra dollar goes directly toward your principal, which means less interest and faster progress toward paying off your balance. 3. Make Lump-Sum Payments Depending on your lender, you may be able to make lump-sum payments of 10–25% of your original mortgage balance each year. This option is ideal if you receive a bonus, inheritance, or other windfall. Applying a lump sum directly to your principal immediately reduces the interest charged for the rest of your term. 4. Review Your Mortgage Annually It’s easy to put your mortgage on auto-pilot, but a yearly review keeps you in control. By sitting down with an independent mortgage professional, you can check if refinancing, restructuring, or adjusting terms could save you money. A quick annual review helps ensure your mortgage is always working for you—not against you. The Bottom Line Paying off your mortgage early doesn’t require a massive lifestyle change—it’s about making smart, consistent choices. Whether it’s accelerated payments, lump sums, or regular reviews, every step you take helps reduce your debt faster. If you’d like to explore strategies tailored to your situation—or want a free annual mortgage review—let’s connect. I’d be happy to help you find the fastest path to mortgage freedom.

The Bank of Canada announced today that it is holding its target for the overnight rate at 2.25%, with the Bank Rate at 2.5% and the deposit rate at 2.20%. The tone of today's announcement is notably more optimistic than previous months. Here's what's changed and what it means for you. What the Bank of Canada Said Signs of Improvement For the first time in several months, the Bank is signalling that Canada's economy is showing real signs of improvement. Growth is picking up, and inflation is projected to ease gradually from its recent spike. While risks remain, particularly around the Middle East conflict and U.S. trade policy, the overall tone has shifted toward cautious optimism. The Global Picture Since the April Monetary Policy Report, global economic prospects have been dampened by higher oil prices from the Middle East conflict. However, the build-out of artificial intelligence is now supporting economic activity in a growing number of countries. Oil prices are still below their April peak, though the situation in the Middle East remains volatile. The U.S. economy is growing at about 2.5%, driven by strong consumer spending and booming AI investment. China continues to expand on the back of robust exports. Europe has been weighed down by high energy prices but is expected to strengthen in the second half of the year if prices ease as anticipated. The Bank projects global GDP growth will slow to 2.75% in 2026 before recovering to around 3.25% in 2027 and 2028. The Canadian Economy Canada's GDP data over the past year has been choppy. Growth stalled as the economy adjusted to new tariffs, high uncertainty, and slower population growth. But there are now clear signs that growth has resumed in the second quarter, estimated at 2.5%. The Bank acknowledges this largely reflects the unwinding of temporary factors, but sources of growth appear to be broadening. Consumer spending looks solid. Housing activity has been weak but is showing signs of stabilizing. Export growth has resumed and is expected to strengthen. Business investment is projected to pick up modestly, boosted in the near term by the oil and gas sector. More businesses also report they are finding ways to navigate through trade uncertainty. Following GDP growth of 0.7% in 2026, the Bank projects growth of 1.8% in both 2027 and 2028. The unemployment rate was 6.5% in June, continuing to hover in the 6.5% to 7% range it has maintained since late 2024. Inflation CPI inflation rose to 3.2% in May, mainly due to higher gasoline prices linked to the Middle East conflict. Excluding gasoline, inflation was just 2.2%, and core inflation measures remained close to 2%. That is an important distinction: the inflation we are seeing is largely an energy story, not a broad cost-of-living surge. Near-term inflation expectations remain sensitive to gasoline prices, but longer-term expectations are well anchored. The Bank expects CPI inflation to stay elevated in June before easing gradually in the coming months, returning to around 2% in early 2027. Inflation is then forecast to average around 2% in 2027 and 2028. Why the Bank Held Governing Council judged that the current rate of 2.25% remains appropriate to sustain the economic recovery and bring inflation back to target. Uncertainty is still high, and the Bank remains prepared to adjust monetary policy as needed. The commitment to price stability remains firm through this period of global upheaval. What This Means for Mortgage Holders and Buyers A rate hold means no immediate change to variable-rate mortgage payments or home equity lines of credit (HELOCs) tied to the prime rate. The prime rate remains at 4.45%. Today's announcement carries a more positive signal than we have seen in recent months. The economy is recovering, core inflation is near target, and the Bank's language suggests the path forward is one of gradual improvement, not further tightening. For borrowers, this is an encouraging environment to plan ahead. If you are renewing a mortgage in the coming months, thinking about purchasing, or weighing your fixed vs. variable options, now is a good time to have that conversation. The landscape is shifting, and being prepared puts you in the best possible position. The next scheduled rate announcement is September 9, 2026 . As always, every borrower's situation is unique.
