    Enter your household income to see what you can afford.

    Estimate only. Uses CMHC GDS (39%) and TDS (44%) ratios and the OSFI B-20 stress test (greater of your rate + 2% or 5.25%). Lenders apply their own credit, income-verification, and down payment rules, and your maximum may differ. Confirm with a mortgage broker or lender.

    How affordability is calculated in Canada

    Two debt-service ratios set the ceiling. The Gross Debt Service ratio caps your housing costs — mortgage, property tax, heat, and half your condo fees — at roughly 39% of gross income. The Total Debt Service ratio adds every other monthly debt and caps the total near 44%. Whichever limit you hit first is the one that sets your maximum, so paying down a car loan or a credit-card balance can raise the price you qualify for.

    Why the stress test lowers the number

    Federally regulated lenders do not qualify you at your contract rate. They use the greater of your rate plus two percentage points or a 5.25% floor. That higher qualifying rate shrinks the mortgage your payment can support, which is the single biggest reason the affordable price is lower than buyers expect.

    Plan for the whole cost of owning

    The mortgage is one line in the cost of a home. Land transfer tax, closing costs, property tax, insurance, and maintenance all add up. Keeping a durable record of your home, its appliances, warranties, and maintenance history is the cheapest insurance a homeowner has. That is what Habyn property records are built to keep, free for homeowners on the Home plan.

    Frequently asked questions

    How much mortgage can I afford in Canada?

    Lenders cap your housing costs at about 39% of gross income (the Gross Debt Service ratio) and your total debts at about 44% (the Total Debt Service ratio). The calculator works backward from those limits, at the stress-test rate, to a maximum mortgage and home price.

    What is the mortgage stress test and does it apply here?

    Federally regulated lenders must qualify you at the greater of your contract rate plus two percentage points or a 5.25% floor. This calculator uses that qualifying rate to size your affordable mortgage, which is why the maximum is lower than your contract rate alone would suggest.

    What are GDS and TDS ratios?

    Gross Debt Service counts your mortgage payment, property tax, heat, and half your condo fees against gross income, capped near 39%. Total Debt Service adds car loans, credit cards, and other debt, capped near 44%. The lower of the two limits sets your maximum.

    Is this the amount a lender will actually approve?

    Treat it as a close estimate. Lenders also weigh your credit score, down payment source, employment, and other factors, and individual policies vary. Confirm your real maximum with a mortgage broker or lender before you shop.
