How Much Difference Will Extra Payments Make Towards My Mortgage?

James DeVuyst • October 3, 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.

Divorce and Your Mortgage: What You Need to Know

By James De Vuyst • November 6, 2025
Going Through a Separation? Here’s What You Need to Know About Your Mortgage Separation or divorce can be one of life’s most stressful transitions—and when real estate is involved, the financial side of things can get complicated fast. If you and your partner own a home together, figuring out what happens next with your mortgage is a critical step in moving forward. Here’s what you need to know: You’re Still Responsible for Mortgage Payments Even if your relationship changes, your obligation to your mortgage lender doesn’t. If your name is on the mortgage, you’re fully responsible for making sure payments continue. Missed payments can lead to penalties, damage your credit, or even put your home at risk of foreclosure. If you relied on your partner to handle payments during the relationship, now is the time to take a proactive role. Contact your lender directly to confirm everything is on track. Breaking or Changing Your Mortgage Comes With Costs Dividing your finances might mean refinancing, removing someone from the title, or selling the home. All of these options come with potential legal fees, appraisal costs, and mortgage penalties—especially if you’re mid-term with a fixed-rate mortgage. Before making any decisions, speak with your lender to get a clear picture of the potential costs. This info can be helpful when finalizing your separation agreement. Legal Status Affects Financing If you're applying for a new mortgage after a separation, lenders will want to see official documentation—like a signed separation agreement or divorce decree. These documents help the lender assess any ongoing financial obligations like child or spousal support, which may impact your ability to qualify. No paperwork yet? Expect delays and added scrutiny in the mortgage process until everything is finalized. Qualifying on One Income Can Be Tougher Many couples qualify for mortgages based on combined income. After a separation, your borrowing power may decrease if you're now applying solo. This can affect your ability to buy a new home or stay in the one you currently own. A mortgage professional can help you reassess your financial picture and identify options that make sense for your situation—whether that means buying on your own, co-signing with a family member, or exploring government programs. Buying Out Your Partner? You May Have Extra Flexibility In cases where one person wants to stay in the home, lenders may offer special flexibility. Unlike traditional refinancing, which typically caps borrowing at 80% of the home’s value, a “spousal buyout” may allow you to access up to 95%—making it easier to compensate your former partner and retain the home. This option is especially useful for families looking to minimize disruption for children or maintain community ties. You Don’t Have to Figure It Out Alone Separation is never simple—but with the right support, you can move forward with clarity and confidence. Whether you’re keeping the home, selling, or starting fresh, working with a mortgage professional can help you understand your options and create a strategy that aligns with your new goals. Let’s talk through your situation and explore the best path forward. I’m here to help.

Fixed vs. Variable Mortgage Rates in Canada

By James De Vuyst • October 23, 2025
Fixed vs. Variable Rate Mortgages: Which One Fits Your Life? Whether you’re buying your first home, refinancing your current mortgage, or approaching renewal, one big decision stands in your way: fixed or variable rate? It’s a question many homeowners wrestle with—and the right answer depends on your goals, lifestyle, and risk tolerance. Let’s break down the key differences so you can move forward with confidence. Fixed Rate: Stability & Predictability A fixed-rate mortgage offers one major advantage: peace of mind . Your interest rate stays the same for the entire term—usually five years—regardless of what happens in the broader economy. Pros: Your monthly payment never changes during the term. Ideal if you value budgeting certainty. Shields you from rate increases. Cons: Fixed rates are usually higher than variable rates at the outset. Penalties for breaking your mortgage early can be steep , thanks to something called the Interest Rate Differential (IRD) —a complex and often costly formula used by lenders. In fact, IRD penalties have been known to reach up to 4.5% of your mortgage balance in some cases. That’s a lot to pay if you need to move, refinance, or restructure your mortgage before the end of your term. Variable Rate: Flexibility & Potential Savings With a variable-rate mortgage , your interest rate moves with the market—specifically, it adjusts based on changes to the lender’s prime rate. For example, if your mortgage is set at Prime minus 0.50% and prime is 6.00% , your rate would be 5.50% . If prime increases or decreases, your mortgage rate will change too. Pros: Typically starts out lower than a fixed rate. Penalties are simpler and smaller —usually just three months’ interest (often 2–2.5 mortgage payments). Historically, many Canadians have paid less overall interest with a variable mortgage. Cons: Your payment could increase if rates rise. Not ideal if rate fluctuations keep you up at night. The Penalty Factor: Why It Matters More Than You Think One of the biggest surprises for homeowners is the cost of breaking a mortgage early —something nearly 6 out of 10 Canadians do before their term ends. Fixed Rate = Unpredictable, potentially high penalty (IRD) Variable Rate = Predictable, usually lower penalty (3 months’ interest) Even if you don’t plan to break your mortgage, life happens—career changes, family needs, or new opportunities could shift your path. So, Which One is Best? There’s no one-size-fits-all answer. A fixed rate might be perfect for someone who wants stable budgeting and plans to stay put for years. A variable rate might work better for someone who’s financially flexible and open to market changes—or who may need to exit their mortgage early. Ultimately, the best mortgage is the one that fits your goals and your reality —not just what the bank recommends. Let's Find the Right Fit Choosing between fixed and variable isn’t just about numbers—it’s about understanding your needs, your future plans, and how much financial flexibility you want. Let’s sit down and walk through your options together. I’ll help you make an informed, confident choice—no guesswork required.

Home Reno Dreams? Let’s Talk Mortgage Financing

By James De Vuyst • October 9, 2025
How to Use Your Mortgage to Finance Home Renovations Home renovations can be exciting—but they can also be expensive. Whether you're upgrading your kitchen, finishing the basement, or tackling a much-needed repair, the cost of materials and labour adds up quickly. If you don’t have all the cash on hand, don’t worry. There are smart ways to use mortgage financing to fund your renovation plans without derailing your financial stability. Here are three mortgage-related strategies that can help: 1. Refinancing Your Mortgage If you're already a homeowner, one of the most straightforward ways to access funds for renovations is through a mortgage refinance. This involves breaking your current mortgage and replacing it with a new one that includes the amount you need for your renovations. Key benefits: You can access up to 80% of your home’s appraised value , assuming you qualify. It may be possible to lower your interest rate or reduce your monthly payments. Timing tip: If your mortgage is up for renewal soon, refinancing at that time can help you avoid prepayment penalties. Even mid-term refinancing could make financial sense, depending on your existing rate and your renovation goals. 2. Home Equity Line of Credit (HELOC) If you have significant equity in your home, a Home Equity Line of Credit (HELOC) can offer flexible funding for renovations. A HELOC is a revolving credit line secured against your home, typically at a lower interest rate than unsecured borrowing. Why consider a HELOC? You only pay interest on the amount you use. You can access funds as needed, which is ideal for staged or ongoing renovations. You maintain the terms of your existing mortgage if you don’t want to refinance. Unlike a traditional loan, a HELOC allows you to borrow, repay, and borrow again—similar to how a credit card works, but with much lower rates. 3. Purchase Plus Improvements Mortgage If you're in the market for a new home and find a property that needs some work, a "Purchase Plus Improvements" mortgage could be a great option. This allows you to include renovation costs in your initial mortgage. How it works: The renovation funds are advanced based on a quote and are held in trust until the work is complete. The renovations must add value to the property and meet lender requirements. This type of mortgage lets you start with a home that might be more affordable upfront and customize it to your taste—all while building equity from day one. Final Thoughts Your home is likely your biggest investment, and upgrading it wisely can enhance both your comfort and its value. Mortgage financing can be a powerful tool to fund renovations without tapping into high-interest debt. The right solution depends on your unique financial situation, goals, and timing.
