Fixed Or Variable Rate Mortgage?

Dean Garrett • January 30, 2025

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."

Thinking About Buying a Home? Here’s What to Know Before You Start Whether you're buying your very first home or preparing for your next move, the process can feel overwhelming—especially with so many unknowns. But it doesn’t have to be. With the right guidance and preparation, you can approach your home purchase with clarity and confidence. This article will walk you through a high-level overview of what lenders look for and what you’ll need to consider in the early stages of buying a home. Once you’re ready to move forward with a pre-approval, we’ll dive into the details together. 1. Are You Credit-Ready? One of the first things a lender will evaluate is your credit history. Your credit profile helps determine your risk level—and whether you're likely to repay your mortgage as agreed. To be considered “established,” you’ll need: At least two active credit accounts (like credit cards, loans, or lines of credit) Each with a minimum limit of $2,500 Reporting for at least two years Just as important: your repayment history. Make all your payments on time, every time. A missed payment won’t usually impact your credit unless you’re 30 days or more past due—but even one slip can lower your score. 2. Is Your Income Reliable? Lenders are trusting you with hundreds of thousands of dollars, so they want to be confident that your income is stable enough to support regular mortgage payments. Salaried employees in permanent positions generally have the easiest time qualifying. If you’re self-employed, or your income includes commission, overtime, or bonuses, expect to provide at least two years’ worth of income documentation. The more predictable your income, the easier it is to qualify. 3. What’s Your Down Payment Plan? Every mortgage requires some amount of money upfront. In Canada, the minimum down payment is: 5% on the first $500,000 of the purchase price 10% on the portion above $500,000 20% for homes over $1 million You’ll also need to show proof of at least 1.5% of the purchase price for closing costs (think legal fees, appraisals, and taxes). The best source of a down payment is your own savings, supported by a 90-day history in your bank account. But gifted funds from immediate family and proceeds from a property sale are also acceptable. 4. How Much Can You Actually Afford? There’s a big difference between what you feel you can afford and what you can prove you can afford. Lenders base your approval on verifiable documentation—not assumptions. Your approval amount depends on a variety of factors, including: Income and employment history Existing debts Credit score Down payment amount Property taxes and heating costs for the home All of these factors are used to calculate your debt service ratios—a key indicator of whether your mortgage is affordable. Start Early, Plan Smart Even if you’re months (or more) away from buying, the best time to start planning is now. When you work with an independent mortgage professional, you get access to expert advice at no cost to you. We can: Review your credit profile Help you understand how lenders view your income Guide your down payment planning Determine how much you can qualify to borrow Build a roadmap if your finances need some fine-tuning If you're ready to start mapping out your home buying plan or want to know where you stand today, let’s talk. It would be a pleasure to help you get mortgage-ready.

When looking to qualify for a mortgage, typically, a lender will want to review four areas of your mortgage application: income, credit, downpayment/equity and the property itself. Assuming you have a great job, excellent credit, and sufficient money in the bank to qualify for a mortgage, if the property you’re looking to purchase isn’t in good condition, if you don't have a plan, you might get some pushback from the lender. The property matters to the lender because they hold it as collateral if you default on your mortgage. As such, you can expect that a lender will make every effort to ensure that any property they finance is in good repair. Because in the rare case that you happen to default on your mortgage, they want to know that if they have to repossess, they can sell the property quickly and recoup their money. So when assessing the property as part of any mortgage transaction, an appraisal is always required to establish value. If your mortgage requires default mortgage insurance through CMHC, Sagen (formerly Genworth), or Canada Guaranty, they’ll likely use an automated system to appraise the property where the assessment happens online. A physical appraisal is required for conventional mortgage applications, which means an appraiser will assess the property on-site. So why is this important to know? Well, because even if you have a great job, excellent credit, and money in the bank, you shouldn’t assume that you’ll be guaranteed mortgage financing. A preapproval can only take you so far. Once the mortgage process has started, the lender will always assess the property you’re looking to purchase. Understanding this ahead of time prevents misunderstandings and will bring clarity to the mortgage process. Practically applied, if you’re attempting to buy a property in a hot housing market and you go in with an offer without a condition of financing, once the appraisal is complete, if the lender isn’t satisfied with the state or value of the property, you could lose your deposit. Now, what happens if you’d like to purchase a property that isn’t in the best condition? Being proactive includes knowing that there is a purchase plus improvements program that can allow you to buy a property and include some of the cost of the renovations in the mortgage. It’s not as simple as just increasing the mortgage amount and then getting the work done, there’s a process to follow, but it’s very doable. So if you have any questions about financing your next property or potentially using a purchase plus improvements to buy a property that needs a little work, please connect anytime. It would be a pleasure to walk you through the process.
