Calgary Mortgage Affordability Calculator
The typical Calgary home runs $629,855 (average selling price, July 2026). To buy it with the minimum down payment you need roughly $130,000 in household income — calculated at the 5.87% stress-test rate, which is what the lender actually uses.
Car loans, lines of credit, minimum card payments, support payments.
Half of it counts against you.
Today's lowest insured five-year fixed on the board.
The stress test is doing the work here
You will pay 3.87%. You are approved at 5.87%. That gap is roughly $669 a month of payment you must show you could carry but will not actually pay.
This is why a calculator that quotes you a payment at the posted rate is misleading. The payment is not the constraint. The qualifying payment is.

That is the useful outcome
Most people who run this discover they do not qualify at the price they had in mind. That is a file worth working, not a dead end — lenders differ enormously on how they treat self-employment income, bonuses, rental offsets and existing debt. Shopping the panel is exactly what changes the answer.

What income do you need to buy a home in Calgary?
About $130,000 a year, on the average selling price of $629,855 with the minimum down payment of $37,986. That figure is calculated at the stress-test rate of 5.87%, not at the 3.87% you would actually pay — lenders qualify you at the higher number.
Why is the qualifying rate higher than the rate I was quoted?
Every federally regulated lender must qualify you at the greater of your contract rate plus two percentage points and 5.25%. At today's 3.87% that means qualifying at 5.87%. It is the single most common reason a pre-approval comes back smaller than people expect.
What are GDS and TDS?
Gross debt service is your housing costs — mortgage payment, property tax, heat, and half of any condo fee — as a share of gross income. Total debt service adds every other monthly obligation. Most lenders want GDS under 39% and TDS under 44%. TDS is what usually binds: a car payment can cost you far more buying power than it looks like it should.
Does a bigger down payment always help?
Not straightforwardly. Crossing 20% removes the insurance premium but moves you off insured pricing onto insurable or uninsured, where rates are higher. Between about 15% and 20% down the arithmetic can genuinely favour putting less down. It is worth running both.
Can I afford Calgary on a single income?
On the typical home, one income needs to be near $130,000. Below that the realistic routes are a larger down payment, a co-signer, moving to a lower price band or a neighbouring market — Lethbridge runs $469,057. A broker is useful here precisely because lenders differ on how they read income.
Price basis: average selling price, July 2026, CREB. Property tax rate 0.618%, confirmed against the municipality. Payments use semi-annual compounding, the Canadian standard. Ratio limits of 39% GDS and 44% TDS are conventional; individual lenders vary.
