How Much Difference Will Extra Payments Make Towards My Mortgage?

Diane Buchanan • July 25, 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.

You’ve most likely heard that there are two certainties in life; death and taxes. Well, as it relates to your mortgage, the single certainty is that you will pay back what you borrow, plus interest. With that said, the frequency of how often you make payments to the lender is somewhat up to you! The following looks at the different types of payment frequencies and how they impact your mortgage. Here are the six payment frequency types Monthly payments – 12 payments per year Semi-Monthly payments – 24 payments per year Bi-weekly payments – 26 payments per year Weekly payments – 52 payments per year Accelerated bi-weekly payments – 26 payments per year Accelerated weekly payments – 52 payments per year Options one through four are straightforward and designed to match your payment frequency with your employer. So if you get paid monthly, it makes sense to arrange your mortgage payments to come out a few days after payday. If you get paid every second Friday, it might make sense to have your mortgage payments match your payday. However, options five and six have that word accelerated before the payment frequency. Accelerated bi-weekly and accelerated weekly payments accelerate how fast you pay down your mortgage. Choosing the accelerated option allows you to lower your overall cost of borrowing on autopilot. Here’s how it works. With the accelerated bi-weekly payment frequency, you make 26 payments in the year. Instead of dividing the total annual payment by 26 payments, you divide the total yearly payment by 24 payments as if you set the payments as semi-monthly. Then you make 26 payments on the bi-weekly frequency at the higher amount. So let’s use a $1000 payment as the example: Monthly payments formula: $1000/1 with 12 payments per year. A payment of $1000 is made once per month for a total of $12,000 paid per year. Semi-monthly formula: $1000/2 with 24 payments per year. A payment of $500 is paid twice per month for a total of $12,000 paid per year. Bi-weekly formula: $1000 x 12 / 26 with 26 payments per year. A payment of $461.54 is made every second week for a total of $12,000 paid per year. Accelerated bi-weekly formula: $1000/2 with 26 payments per year. A payment of $500 is made every second week for a total of $13,000 paid per year. You see, by making the accelerated bi-weekly payments, it’s like you end up making two extra payments each year. By making a higher payment amount, you reduce your mortgage principal, which saves interest on the entire life of your mortgage. The payments for accelerated weekly payments work the same way. It’s just that you’d be making 52 payments a year instead of 26. By choosing an accelerated option for your payment frequency, you lower the overall cost of borrowing by making small extra payments as part of your regular payment schedule. Now, exactly how much you’ll save over the life of your mortgage is hard to nail down. Calculations are hard to do because of the many variables; mortgages come with different amortization periods and terms with varying interest rates along the way. However, an accelerated bi-weekly payment schedule could reduce your amortization by up to three years if maintained throughout the life of your mortgage. If you’d like to look at some of the numbers as they relate to you and your mortgage, please don’t hesitate to connect anytime; it would be a pleasure to work with you.

Thinking of Buying a Home? Here’s Why Getting Pre-Approved Is Key If you’re ready to buy a home but aren’t sure where to begin, the answer is simple: start with a pre-approval. It’s one of the most important first steps in your home-buying journey—and here's why. Why a Pre-Approval is Crucial Imagine walking into a restaurant, hungry and excited to order, but unsure if your credit card will cover the bill. It’s the same situation with buying a home. You can browse listings online all day, but until you know how much you can afford, you’re just window shopping. Getting pre-approved for a mortgage is like finding out the price range you can comfortably shop within before you start looking at homes with a real estate agent. It sets you up for success and saves you from wasting time on properties that might be out of reach. What Exactly is a Pre-Approval? A pre-approval isn’t a guarantee. It’s not a promise that a lender will give you a mortgage no matter what happens with your finances. It’s more like a preview of your financial health, giving you a clear idea of how much you can borrow, based on the information you provide at the time. Think of it as a roadmap. After going through the pre-approval process, you’ll have a much clearer picture of what you can afford and what you need to do to make the final approval process smoother. What Happens During the Pre-Approval Process? When you apply for a pre-approval, lenders will look at a few key areas: Your income Your credit history Your assets and liabilities The property you’re interested in This comprehensive review will uncover any potential hurdles that could prevent you from securing financing later on. The earlier you identify these challenges, the better. Potential Issues a Pre-Approval Can Reveal Even if you feel confident that your finances are in good shape, a pre-approval might uncover issues you didn’t expect: Recent job changes or probation periods An income that’s heavily commission-based or reliant on extra shifts Errors or collections on your credit report Lack of a well-established credit history Insufficient funds saved for a down payment Existing debt reducing your qualification amount Any other financial blind spots you might not be aware of By addressing these issues early, you give yourself the best chance of securing the mortgage you need. A pre-approval makes sure there are no surprises along the way. Pre-Approval vs. Pre-Qualification: What’s the Difference? It’s important to understand that a pre-approval is more than just a quick online estimate. Unlike pre-qualification—which can sometimes be based on limited information and calculations—a pre-approval involves a thorough review of your finances. This includes looking at your credit report, providing detailed documents, and having a conversation with a mortgage professional about your options. Why Get Pre-Approved Now? The best time to secure a pre-approval is as soon as possible. The process is free and carries no risk—it just gives you a clear path forward. It’s never too early to start, and by doing so, you’ll be in a much stronger position when you're ready to make an offer on your dream home.
