What this Canadian mortgage calculator includes
The tool calculates principal and interest using the Canadian fixed-rate convention, estimates the federal minimum down payment and adds the standard mortgage-default insurance premium when the loan-to-value ratio is above 80%.
How to read the stress-test result
Your contract payment is what the selected rate produces. The qualification payment uses the higher of 5.25% or your contract rate plus two percentage points. Estimated GDS and TDS ratios provide context, but a lender will verify income, debts, credit, property expenses and insurer requirements.

Canadian Mortgage Calculator — Frequently Asked Questions
For a typical Canadian fixed-rate mortgage, the quoted nominal annual interest rate is converted using semi-annual compounding, then applied to the selected monthly amortization schedule. This differs from the monthly-compounding convention commonly used by US calculators.
