How it's calculated
- Lenders test you at the greater of your rate plus 2% and 5.25%, not at the rate you will actually pay.
- Housing costs are the mortgage payment, property tax, heat and half of any condo fees. They can be at most 39% of gross income (GDS). Adding your other debts, the limit is 44% (TDS).
- With under 20% down, the insurance premium is added to the mortgage. The calculator finds the highest price that passes both limits.
- The minimum down payment is 5% of the first $500,000 and 10% of the rest. A home at $1.5 million or more needs 20% down.
- Property tax starts at the Calgary 2026 rate and heating at a typical figure. Change both for your own home.
Frequently asked questions
What is the mortgage stress test?
Lenders must check that you could still pay if rates rose. You qualify at your contract rate plus 2%, or 5.25%, whichever is higher.
What are GDS and TDS?
Gross debt service is your housing costs divided by gross income. Total debt service adds your other debts. The limits are 39% and 44%.
Can I get a 30-year amortization?
With under 20% down, only first-time buyers and buyers of newly built homes can. A longer amortization lowers the payment, so you can afford a higher price. Use the switches above to see it.
Why might my bank approve a different amount?
Lenders also weigh credit history, job type and rules this calculator leaves out. Treat the result as a planning number and get a pre-approval before you start shopping.
