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.

Thinking About Selling Your Home? Start With These 3 Key Questions Selling your home is a major move—emotionally, financially, and logistically. Whether you're upsizing, downsizing, relocating, or just ready for a change, there are a few essential questions you should have answers to before you list that "For Sale" sign. 1. How Will I Get My Home Sale-Ready? Before your property hits the market, you’ll want to make sure it puts its best foot forward. That starts with understanding its current market value—and ends with a plan to maximize its appeal. A real estate professional can walk you through what similar homes in your area have sold for and help tailor a prep plan that aligns with current market conditions. Here are some things you might want to consider: Decluttering and removing personal items Minor touch-ups or repairs Fresh paint inside (and maybe outside too) Updated lighting or fixtures Professional staging Landscaping or exterior cleanup High-quality photos and possibly a virtual tour These aren’t must-dos, but smart investments here can often translate to a higher sale price and faster sale. 2. What Will It Actually Cost to Sell? It’s easy to look at the selling price and subtract your mortgage balance—but the real math is more nuanced. Here's a breakdown of the typical costs involved in selling a home: Real estate agent commissions (plus GST/HST) Legal fees Mortgage discharge fees (and possibly a penalty) Utility and property tax adjustments Moving expenses and/or storage costs That mortgage penalty can be especially tricky—it can sometimes be thousands of dollars, depending on your lender and how much time is left in your term. Not sure what it might cost you? I can help you estimate it. 3. What’s My Plan After the Sale? Knowing your next step is just as important as selling your current home. If you're buying again, don’t assume you’ll automatically qualify for a new mortgage just because you’ve had one before. Lending rules change, and so might your financial situation. Before you sell, talk to a mortgage professional to find out what you’re pre-approved for and what options are available. If you're planning to rent or relocate temporarily, think about timelines, storage, and transition costs. Clarity and preparation go a long way. The best way to reduce stress and make confident decisions is to work with professionals you trust—and ask all the questions you need. If you’re thinking about selling and want help mapping out your next steps, I’d be happy to chat anytime. Let’s make a smart plan, together.

As patios wind down and pumpkin spice ramps up, fall is the perfect reset for your home—and your homeowner game plan. These quick wins boost comfort, curb appeal, and efficiency now, and set you up for a low-stress winter (and a strong spring market). 1) Safety & “silent leak” checks (Weekend-ready) Clean gutters & downspouts. Add leaf guards where trees overhang. Roof scan. Look for lifted shingles, cracked flashings, or moss. Seal the shell. Re-caulk window/door trim; replace weatherstripping. Test alarms. New batteries for smoke/CO detectors; add one near bedrooms. Why it matters: Prevent water intrusion and heat loss before storms roll in. 2) Heat smarter, not harder Furnace/boiler tune-up and filter change. Smart thermostat with schedules and geofencing. Draft hunt. Foam gaskets behind outlets, door sweeps on exterior doors. ROI tip: Efficiency upgrades lower monthly bills and can improve lender ratios if you’re eyeing a refinance later. 3) Fall-proof your yard (so spring you says “thanks”) Aerate + overseed + fall fertilize for thicker turf next year. Trim trees/shrubs away from siding and power lines. Mulch perennials and plant spring bulbs now. Shut off/bleed exterior taps and store hoses to avoid burst pipes. 4) Extend outdoor season (cozy edition) Portable fire pit or propane heater + layered blankets. Path/step lighting for darker evenings (solar or low-voltage). Weather-resistant storage for cushions/tools to preserve value. Neighborhood curb appeal: Warm lighting and tidy beds make a big first impression if you list in shoulder season. 5) Water management = winter peace of mind Re-grade low spots and add downspout extensions (2–3+ metres). Check sump pump (and backup). Look for efflorescence or damp corners in the basement. 6) Mini-renos that punch above their weight Entry/mudroom upgrade: hooks, bench, boot trays, closed storage. Laundry room tune-up: counter over machines, sorting bins, task lighting. Kitchen refresh: new hardware, tap, and under-cabinet lighting in one afternoon. Budget guide: Many of these land under a micro-reno budget—perfect for a modest line of credit. 7) Indoor air quality tune-up Deep clean vents and dryers (including the rigid duct). Add door mats (exterior + interior) to catch grit/salt. Houseplants or HEPA purifier for closed-window months. Fast Timeline (pin this to the fridge) Late August–September Gutters/downspouts, roof/caulking, HVAC service, lawn care, plant bulbs, exterior tap shut-off plan, path lighting. October Weatherstripping/sweeps, fire pit setup, organize mudroom/garage, test alarms, sump check, downspout extensions, dryer vent cleaning. Financing smarter: make your mortgage work for your home Annual mortgage check-in. As rates, income, and goals evolve, a quick review can free up cash flow or open options for a small fall project budget. HELOC vs. top-up refinance. For bite-size projects, a HELOC can be flexible. For bigger renos you plan to pay down, a top-up refi might make more sense. Bundle & prioritize. Knock out the high-impact, low-cost items first (air sealing, safety, water management) before the cosmetic upgrades. Not sure which route fits your fall plans?
