Canadian mortgage affordability & stress-test calculator

See both your actual mortgage payment and the higher stress-test payment used in this uninsured planning scenario.

Your inputs

Gross annual household income (C$)Before tax, for all co-borrowers.

Home purchase price (C$)Owner-occupied conventional mortgage scenario.

Down payment (C$)At least 20% of home price for this uninsured-mortgage model.

Why a 20% down-payment limit?

This tool models uninsured mortgages only. The maximum home price is the smaller of the debt-service ceiling and your fixed down payment divided by 20%. Higher income cannot remove the cash-down limit.

Contract mortgage rate (%)Illustrative rate, not a rate quote.

Amortization (years)1–30 years for this planning model; lender maximums may differ.

Annual property tax (C$)Your estimate for this specific property.

Monthly heating cost (C$)FCAC includes heating in GDS.

Monthly condo fees (C$)Only half included in the standard GDS/TDS model.

Other monthly debt payments (C$)Auto loans, minimum credit payments and other debts.

Calculation breakdown

Uninsured mortgages only: at least 20% down. This is a planning limit, not mortgage approval.

What this result includes—and excludes

The numbers are editable planning scenarios and are not professional advice, quotes or eligibility decisions. No entered information is submitted to a server by this calculator.

How the calculation works

Qualifying annual rate = max(5.25%, contract rate + 2%). Convert a Canadian nominal annual mortgage rate compounded semi-annually into a monthly effective rate. Mortgage payment = P×i/[1−(1+i)^(−12×years)]. GDS = [qualifying payment + tax/12 + heat + ½ condo fees]/gross monthly income. TDS includes other debt payments. Maximum mortgage uses the tighter of 39% GDS and 44% TDS capacities; the maximum modelled purchase price holds your entered down payment and property tax fixed. This excludes insured mortgages.

Understand the calculation

Before relying on the scenario, read Mortgage stress test: what qualification really means for its assumptions, worked examples and official-source references.
