Fixed-Rate or Variable-Rate Mortgage?

Lisa Manwaring • October 16, 2024

If you're looking to buy a new property, refinance, or renew an existing mortgage, chances are, you're considering either a fixed or variable rate mortgage. Figuring out which one is the best is entirely up to you! So here's some information to help you along the way.


Firstly, let's talk about the fixed-rate mortgage as this is most common and most heavily endorsed by the banks. With a fixed-rate mortgage, your interest rate is "fixed" for a certain term, anywhere from 6 months to 10 years, with the typical term being five years. If market rates fluctuate anytime after you sign on the dotted line, your mortgage rate won't change. You're a rock; your rate is set in stone. Typically a fixed-rate mortgage has a higher rate than a variable.


Alternatively, a variable rate is not set in stone; instead, it fluctuates with the market. The variable rate is a component (either plus or minus) to the prime rate. So if the prime rate (set by the government and banks) is 2.45% and the current variable rate is Prime minus .45%, your effective rate would be 2%. If three months after you sign your mortgage documents, the prime rate goes up by .25%, your rate would then move to 2.25%. Typically, variable rates come with a five-year term, although some lenders allow you to go with a shorter term.


At first glance, the fixed-rate mortgage seems to be the safe bet, while the variable-rate mortgage appears to be the wild card. However, this might not be the case. Here's the problem, what this doesn't account for is the fact that a fixed-rate mortgage and a variable-rate mortgage have two very different ways of calculating the penalty should you need to break your mortgage.


If you decide to break your variable rate mortgage, regardless of how much you have left on your term, you will end up owing three months interest, which works out to roughly two to two and a half payments. Easy to calculate and not that bad.


With a fixed-rate mortgage, you will pay the greater of either three months interest or what is called an interest rate differential (IRD) penalty. As every lender calculates their IRD penalty differently, and that calculation is based on market fluctuations, the contract rate at the time you signed your mortgage, the discount they provided you at that time, and the remaining time left on your term, there is no way to guess what that penalty will be. However, with that said, if you end up paying an IRD, it won't be pleasant.


If you've ever heard horror stories of banks charging outrageous penalties to break a mortgage, this is an interest rate differential. It's not uncommon to see penalties of 10x the amount for a fixed-rate mortgage compared to a variable-rate mortgage or up to 4.5% of the outstanding mortgage balance.


So here's a simple comparison.


A fixed-rate mortgage has a higher initial payment than a variable-rate mortgage but remains stable throughout your term. The penalty for breaking a fixed-rate mortgage is unpredictable and can be upwards of 4.5% of the outstanding mortgage balance.


A variable-rate mortgage has a lower initial payment than a fixed-rate mortgage but fluctuates with prime throughout your term. The penalty for breaking a variable-rate mortgage is predictable at 3 months interest which equals roughly two and a half payments.


The goal of any mortgage should be to pay the least amount of money back to the lender. This is called lowering your overall cost of borrowing. While a fixed-rate mortgage provides you with a more stable payment, the variable rate does a better job of accommodating when "life happens."

Bank of Canada Rate Announcement Sept 17th, 2025

By Lisa Manwaring • September 17, 2025
Bank of Canada lowers policy rate to 2½%.  FOR IMMEDIATE RELEASE Media Relations Ottawa, Ontario September 17, 2025 The Bank of Canada today reduced its target for the overnight rate by 25 basis points to 2.5%, with the Bank Rate at 2.75% and the deposit rate at 2.45%. After remaining resilient to sharply higher US tariffs and ongoing uncertainty, global economic growth is showing signs of slowing. In the United States, business investment has been strong but consumers are cautious and employment gains have slowed. US inflation has picked up in recent months as businesses appear to be passing on some tariff costs to consumer prices. Growth in the euro area has moderated as US tariffs affect trade. China’s economy held up in the first half of the year but growth appears to be softening as investment weakens. Global oil prices are close to their levels assumed in the July Monetary Policy Report (MPR). Financial conditions have eased further, with higher equity prices and lower bond yields. Canada’s exchange rate has been stable relative to the US dollar. Canada’s GDP declined by about 1½% in the second quarter, as expected, with tariffs and trade uncertainty weighing heavily on economic activity. Exports fell by 27% in the second quarter, a sharp reversal from first-quarter gains when companies were rushing orders to get ahead of tariffs. Business investment also declined in the second quarter. Consumption and housing activity both grew at a healthy pace. In the months ahead, slow population growth and the weakness in the labour market will likely weigh on household spending. Employment has declined in the past two months since the Bank’s July MPR was published. Job losses have largely been concentrated in trade-sensitive sectors, while employment growth in the rest of the economy has slowed, reflecting weak hiring intentions. The unemployment rate has moved up since March, hitting 7.1% in August, and wage growth has continued to ease. CPI inflation was 1.9% in August, the same as at the time of the July MPR. Excluding taxes, inflation was 2.4%. Preferred measures of core inflation have been around 3% in recent months, but on a monthly basis the upward momentum seen earlier this year has dissipated. A broader range of indicators, including alternative measures of core inflation and the distribution of price changes across CPI components, continue to suggest underlying inflation is running around 2½%. The federal government’s recent decision to remove most retaliatory tariffs on imported goods from the US will mean less upward pressure on the prices of these goods going forward. With a weaker economy and less upside risk to inflation, Governing Council judged that a reduction in the policy rate was appropriate to better balance the risks. Looking ahead, the disruptive effects of shifts in trade will continue to add costs even as they weigh on economic activity. Governing Council is proceeding carefully, with particular attention to the risks and uncertainties. Governing Council will be assessing how exports evolve in the face of US tariffs and changing trade relationships; how much this spills over into business investment, employment, and household spending; how the cost effects of trade disruptions and reconfigured supply chains are passed on to consumer prices; and how inflation expectations evolve. The Bank is focused on ensuring that Canadians continue to have confidence in price stability through this period of global upheaval. We will support economic growth while ensuring inflation remains well controlled. Information note The next scheduled date for announcing the overnight rate target is October 29, 2025. The Bank’s October Monetary Policy Report will be released at the same time.

Smart Steps to Get Your Home Market-Ready

By Lisa Manwaring • September 10, 2025
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.
