How Much House Can I Afford on a $100,000 Salary in Canada? (2026)

Short answer

On a $100,000 income in Canada, how much mortgage and home price can you afford? The GDS/TDS math, a table by down payment and debt, a worked example, and what changes it.

A $100,000 income is a common milestone, and the natural next question in 2026 is "what home does that actually buy?" The answer isn't a single number — it swings with your down payment, your other debts, property costs, and the stress test. But you can pin down a realistic range with the same two ratios every Canadian lender uses. Below is the direct answer, a table that shows how the number moves, the math behind it, and the levers that change it.

The short answer

On a $100,000 household income with modest debt and 20% down, you can typically afford a mortgage of roughly $410,000 to $450,000, supporting a home price of about $515,000 to $560,000 — qualifying at an illustrative stress-test rate near 6.5%. With 5% down on a smaller home, the price lands closer to $430,000 to $470,000 because the mortgage is insured and your ratios tighten. Carry a $500/month car payment and you lose roughly $70,000 to $90,000 of buying power. Run your real number on the affordability calculator.

How much house $100k buys, by down payment and debt

The table below shows approximate maximum home prices on a $100,000 household income, qualifying at an illustrative stress-test rate of 6.5% over a 25-year amortization. Figures are for illustration only and assume typical property tax and heating costs.

Other monthly debt5% down10% down20% down
$0~$465,000~$495,000~$555,000
$300~$425,000~$455,000~$510,000
$500~$395,000~$425,000~$475,000
$800~$350,000~$380,000~$420,000

Two patterns stand out. First, every $300 of monthly debt knocks roughly $40,000 to $45,000 off your price — that's the TDS ratio biting. Second, a bigger down payment helps both by shrinking the mortgage and by removing the mortgage-insurance premium once you reach 20%.

The GDS and TDS math behind the number

Lenders cap your borrowing with two debt-service ratios:

  • GDS (Gross Debt Service): housing costs — mortgage payment, property tax, heat, and half of any condo fees — should stay under about 39% of gross income.
  • TDS (Total Debt Service): housing plus all other debt payments (car loans, credit cards, lines of credit, student loans) should stay under about 44% of gross income.

On $100,000 gross ($8,333/month), 39% GDS is about $3,250/month for housing, and 44% TDS is about $3,667/month for housing plus debts. Whichever limit you hit first sets your ceiling — which is exactly why paying down a loan can unlock more mortgage room. See the full breakdown in our income required for a mortgage guide.

The stress test lowers your maximum

You don't qualify at your contract rate — you qualify at the greater of your contract rate plus 2% or 5.25%. So even if you're offered, say, 4.4%, the lender tests your payments at about 6.4%. That higher payment is what gets measured against the 39%/44% caps, which is why your approved amount is lower than a quick "rate times income" guess. Check yours with the stress-test calculator.

A worked example

Priya earns $100,000 ($8,333/month) and has a $350/month car payment. With 20% down and no other debt, her GDS room is about $3,250/month. After roughly $400/month for property tax and $150 for heat, about $2,700 supports her mortgage payment — calculated at an illustrative 6.5% stress-test rate, that's a mortgage near $400,000. Her $350 car payment still leaves her comfortably inside the 44% TDS cap, so GDS is her binding limit. Add a 20% down payment and her price range lands around $500,000. If she clears the car loan before applying, her TDS room frees up and she can direct slightly more to housing — nudging her price higher. The affordability calculator runs this in seconds.

How a co-applicant or less debt changes it

Two levers move the number the most:

  • Adding a co-applicant: a partner's income is added to the household total, and the ratios are applied to the combined figure. A second $60,000 income can lift the affordable price by well over $250,000 — provided the co-applicant doesn't bring heavy debt of their own.
  • Reducing debt: because TDS counts every monthly payment, eliminating a $500 car payment can restore $70,000 to $90,000 of buying power. Paying off a credit-card balance helps the same way and improves your credit profile.
  • Down payment size: reaching 20% removes mortgage-default-insurance premiums and widens your options.
  • Credit and income type: a strong score (680+) keeps you at prime lenders, and salaried income is the most straightforward to document.

Affordable vs. approved

The lender's maximum is a ceiling, not a target. Borrowing the full amount on a $100,000 income can leave little buffer for a higher payment at renewal, maintenance, or a change in circumstances. Build in room, then lock in your real figure with a pre-approval before you shop.

Frequently asked questions

How much house can I afford on $100,000 a year in Canada?

With modest debt and 20% down, roughly a $515,000 to $560,000 home (a mortgage near $410,000 to $450,000) at an illustrative stress-test rate. The exact figure depends on your debts, down payment, property costs, and rate.

What mortgage can I get on $100,000 income?

Typically a mortgage of about $400,000 to $450,000 if your other debts are low, qualifying at the greater of your contract rate plus 2% or 5.25%. Higher debts or property costs lower it.

Does a $500 car payment really matter that much?

Yes. Because it counts in your TDS ratio, a $500 monthly payment can reduce your affordable home price by roughly $70,000 to $90,000. Clearing it before applying often restores that room.

How does adding my partner's income change what we can afford?

Lenders combine both incomes and apply the GDS/TDS ratios to the total. A second income can add hundreds of thousands to your price range, as long as the co-applicant's own debts are manageable.

Do I need 20% down on a $100,000 salary?

No. You can buy with as little as 5% down on homes up to $500,000 (and a tiered amount above that), but the mortgage will be insured and your ratios are slightly tighter. Reaching 20% removes the insurance premium and widens your choices.
