Mortgage Qualification Calculator
Model a purchase end to end — CMHC insurance, the federal stress test, GDS/TDS qualification, Alberta closing costs, accelerated payment frequencies, prepayments, and a rate you set for every renewal across the amortization. Built on current Canadian rules (the December 2024 reforms). For illustration only.

Ratios use the payment at the stress-test qualifying rate, not your contract rate — that's how a lender sizes the mortgage. GDS = housing ÷ income; TDS = (housing + debts) ÷ income.

Results are estimates based on the inputs you provide and current published Canadian rules (CMHC premiums, the December 2024 amortization and $1.5M insured-cap reforms, the OSFI/CMHC stress test, and Alberta Land Titles fees). The rate-per-renewal projection is speculative — future renewal rates are unknown and the figures shown assume the rates you set. Actual rates, lender criteria, insurer approval, qualification, and closing costs will differ. Payments use Canadian semi-annual compounding; each renewal re-amortizes the remaining balance over the remaining amortization. Consult a licensed mortgage professional before making any decision.
