Guide to mortgage affordability

What is mortgage affordability, and why does it matter?

Mortgage affordability refers to how much you’re able to borrow based on your current income, debt and living expenses. It’s essentially your purchasing power when buying a home. The higher your mortgage affordability, the more expensive a home you can afford to purchase.

In addition to the mortgage itself, it's crucial to account for other cash requirements, such as your down payment and closing costs. These costs, which can be estimated using the Cash Needed tab in our mortgage affordability calculator, will help you gauge the full financial commitment of purchasing a home.

Several factors impact your mortgage affordability, including your household income, monthly debt payments (like car loans or credit card bills), and the ongoing costs of homeownership (e.g., property taxes, condo fees, and heating). By understanding both your borrowing capacity and the cash required to complete a purchase, you’ll be better equipped to determine what kind of home fits your budget.

July 2025 Canadian mortgage affordability update

In June 2025, it became more difficult to afford a home in nearly every major Canadian city, according to the latest Affordability Report from Ratehub.ca. The report found that affordability declined in 12 out of 13 markets last month.

The average five-year fixed mortgage rate used in the report increased from 4.38% in May to 4.48% in June, pushing the mortgage stress test rate up to 6.48%. Bond yields – which influence fixed rates – have been on the rise due to ongoing trade tensions and stronger-than-expected economic indicators. Meanwhile, expectations for further cuts to the Bank of Canada’s overnight lending rate, which affects variable rates, have faded as inflation and job numbers remain robust. These higher rates, paired with rising home prices in more than half of the markets analyzed, squeezed affordability even further.

St. John’s experienced the sharpest deterioration, with the average home price rising by $9,500 to $387,800, increasing the income required to qualify for a mortgage by $2,450 to $88,910. On the other end of the spectrum, Toronto was the only market to see an improvement. Thanks to a substantial $17,700 drop in average home price, bringing it below $1 million, buyers in Toronto needed $1,160 less in household income to qualify. Looking ahead, the affordability outlook remains uncertain.

How to use the mortgage affordability calculator

To use our mortgage affordability calculator, simply enter your and your co-applicant’s income (if applicable), as well as your living costs and debt payments. The calculator can estimate your living expenses if you don’t know them.

With these numbers, you’ll be able to calculate how much you can afford to borrow. You can also change your amortization period and mortgage rate to see how that would affect your mortgage affordability and your monthly payments.

How to increase your mortgage affordability

If you want to increase how much you can borrow, thus increasing how much you can afford to spend on a home, there are few steps you can take.

1. Save a larger down payment: The larger your down payment, the less interest you’ll be charged over the life of your loan. A larger down payment also saves you money on the cost of mortgage default insurance

2. Get a better mortgage rate: Shop around for the best mortgage rate you can find, and consider using a mortgage broker to negotiate on your behalf. A lower mortgage rate will result in lower monthly payments, increasing how much you can afford. It will also save you thousands of dollars over the life of your mortgage.

3. Increase your amortization periodThe longer you take to pay off your loan, the lower your monthly payments will be, making your mortgage more affordable. However, this will result in you paying more interest over time. These are just a few ways you can increase the amount you can afford to spend on a home, by increasing your mortgage affordability. However, the best advice will be personal to you. Find a licensed mortgage broker near you to have a free, no-obligation conversation that’s tailored to your needs and free of charge.

4. Take advantage of the proposed GST exemption: In March 2025, Prime Minister Mark Carney’s government introduced a plan to remove the 5% GST for first-time home buyers who purchase newly constructed or substantially renovated homes priced up to $1 million. The Conservative Party has also floated a similar proposal that would extend the exemption to homes valued up to $1.3 million, without limiting eligibility to first-time buyers. The exact scope of this policy will depend on the outcome of the federal election on April 28, 2025.
