Know your number.

Before you fall in love with a listing, know what you can actually qualify for. This calculator applies the same GDS and TDS ratios lenders use, at the mortgage stress test rate, to give you a realistic maximum purchase price.

It's a starting point — not a guarantee. Your actual approval depends on your credit profile, employment history, and your lender's specific policies.

How this is calculated

GDS & TDS ratios explained.

Ratio	Limit	What it measures
GDS	39% max	Housing costs ÷ gross income
TDS	44% max	Housing + all debts ÷ gross income

Stress test: lenders qualify you at the greater of your contract rate + 2% or 5.25% — not your actual rate. This calculator applies the same test.

The figures below reflect current Canadian lending guidelines. Housing costs include an estimated principal & interest payment, property tax, and heating — connect with Shanna for a broker referral to confirm your exact number.
