Home Affordability Calculator

Find out exactly how much home you can afford in Canada โ€” including the stress test, GDS/TDS ratios, and CMHC insurance rules.

๐Ÿ“

How Canadian lenders determine what you can afford

Canadian banks use two ratios: GDS (max 39%) โ€” housing costs vs. income, and TDS (max 44%) โ€” all debt vs. income. They also apply the mortgage stress test, requiring you to qualify at your rate + 2%. This calculator applies all three rules.

๐Ÿ’ก Home Buying Tips for Canadians

๐Ÿงช Stress Test Reality

The stress test means you must qualify at your rate + 2%. If you get 4.79%, you must prove you can afford payments at 6.79%. This protects you if rates rise.

๐Ÿ’ฐ The 20% Magic Number

A 20% down payment eliminates CMHC insurance (which can add thousands to your mortgage) and gives you immediate equity in your home.

๐Ÿฆ Shop Multiple Lenders

Even a 0.25% rate difference on a $500K mortgage saves over $15,000 in interest over 5 years. Always compare banks, credit unions, and brokers.

๐Ÿ“‹ Get Pre-Approved First

A pre-approval locks in your rate for 90โ€“120 days and shows sellers you're serious. It also reveals your exact budget before you start house hunting.
