The housing market in Canada has been tricky to navigate for the last few years. Not only do Canadians have to worry about availability because there are fewer homes for sale than in previous years, but affordability has also become a huge concern. If you are looking to purchase a home but you’re not sure how much house you can afford, this guide will help set you in the right direction.
How Do I Estimate Home Affordability?

The first question you might ask yourself when you plan to buy a home is, “How much house can I afford?” or ” What is my maximum purchase price?” The maximum price you can afford (sometimes called your budget) is based on two key factors: the size of your mortgage and your down payment.

Your income usually determines the size of your mortgage. In contrast, the size of your down payment depends on how much money you’ve saved and whether you can get money from sources like family or inheritance.
For example, let’s say you’ve saved $50,000 for your home down payment, and your parents are chipping in an additional $25,000 as a gift. That gives you a total down payment size of $75,000.
In addition, based on your income, your lender has agreed to lend you $400,000. Your total home affordability, or your budget, is:
$75,000 (down payment) + $400,000 (mortgage) = $475,000
Determining How Much Down Payment Do You Need

In Canada, there are requirements for how much you need to have as a minimum down payment, depending on the home’s purchase price.
If the home is $500,000 or less, you need a minimum down payment of 5%.
However, if the home is between $500,000 and $1,499,999, you will need a down payment of at least 5% up to $500,000 and 10% of the remaining difference.
Lastly, if the home is $1,500,000 or more, you need a minimum down payment of 20%.
For example, if you planned to purchase a home for $650,000, you would need a down payment of 5% on the first $500,000 = $25,000 and 10% on the remaining $150,000 = $15,000 for a total minimum down payment size of $40,000.
Remember, no matter the purchase price, if your down payment is less than 20% of the price of your home, you will need to buy mortgage default insurance, sometimes called CMHC insurance. This insurance protects the lender if you default on your mortgage (it doesn’t protect you!) and can be added to your mortgage payments or included as a lump sum. The cost varies and will be calculated when you apply for a mortgage based on your home’s purchase price and down payment size.
How Much Monthly Mortgage Can I Afford?
The second part of the “how much house can I afford” question is the size of the mortgage you can afford. How much mortgage you can afford (often called your mortgage affordability) depends on your income, debts, and estimated housing costs.
These factors are considered by lenders using two formulas: your gross debt service ratio (GDS) and your total debt service ratio (TDS).
Gross Debt Service Ratio
Lenders use the gross debt service ratio (GDS) formula to ensure you can comfortably afford your monthly house costs based on your income.

GDS takes your total monthly housing costs as a percentage of your gross monthly income. The percentage cannot exceed 39%. Your monthly housing costs will include:
- Mortgage payments
- Property taxes
- Heating costs
- Condo fees (if applicable)
For example, let’s assume you earn $100,000 per year or $8,333 per month. Using the GDS, the maximum housing costs you can afford while maintaining a safe 39% ratio is $3,250 in housing costs. Your monthly housing costs might look like this:
- Mortgage payments: $2,750
- Property taxes: $300
- Heating costs: $200
Your monthly housing costs would consist of your mortgage payments ($2,750), property taxes ($300), and heating costs ($200), totalling $3,250, which is 39% of your gross monthly income.
Total Debt Service Ratio
While your GDS ratio is a good place to start when determining how much monthly mortgage payment you can afford, you’ll also need to consider whether you can afford your mortgage in addition to your monthly debt payments. In this case, a calculation called your total debt service ratio comes into play.

TDS takes your monthly housing costs and minimum debt payments as a percentage of your gross income. Your debt payments could include:
- Car payments
- Student loan payments
- Line of credit minimum payments
- Credit card minimum payments
Your TDS ratio cannot exceed 44% of your gross monthly income.
For example, assume you earn $100,000 per year or $8,333 per month. your monthly housing costs add up to $3,250, as in the example above, but you also have a car loan for $415 monthly. Your total expenses would be:
- Mortgage payments: $2,750
- Property taxes: $300
- Heating costs: $200
- Car loan: $415
Your total costs would total $3,665, which is about 44% of your gross monthly income.
Your Down Payment and Your Mortgage Affordability is How Much House You Can Afford
We mentioned above that you can determine how much house you can afford by combining your down payment amount with your maximum mortgage size. You can use a mortgage affordability calculator to determine your maximum mortgage size, and that calculator will use the same GDS and TDS ratios we mentioned above.
Once you add your maximum mortgage size to your down payment amount, you’ll know definitively how much house you can afford.
How to Improve Mortgage Affordability and Your Maximum Purchase Price

The cost of homes and rising interest rates make it increasingly difficult for many Canadians to afford a home. However, if you want to improve your mortgage affordability and increase your maximum purchase price, you can take a few steps.
- Increase your income—The most obvious answer is to get more money. Of course, this is often easier said than done, but it might be worth talking with your current employer. Maybe it’s time to ask for a raise or promotion that will come with a pay increase. Perhaps you can ask for more hours at your current job or pick up a second one.
- Decrease your debt – As mentioned in this article, your TDS will significantly determine how much of a house you can afford. Having as low a TDS as possible is best to maximize affordability and mortgage loan approval. If your TDS is high, consider paying off some of your debts before shopping for a home.
- Increase the size of your down payment – the larger your down payment, the more home you can afford, or, the smaller your required mortgage and corresponding monthly mortgage payment. Therefore, if you want to increase your home purchase budget, increasing the size of your down payment will help.
- Improve your credit – Your credit score and credit history play a large role in determining mortgage affordability. As a result, a higher credit score will give you access to better mortgage rates, increasing your affordability.
