Advanced · lender ratios and assumptions

39% and 44% are the insured ceilings. Lenders set their own, and a strong file can go higher, so change these to match the lender you're working with.

How the ratios land

GDS, housing costs

39.0% of 39%

TDS, housing plus debtssets your limit

44.0% of 44%

GDS is housing cost against gross income. TDS adds every other debt payment. A lender has to pass both, so the tighter one is what decides the number above.

  • Your down payment reaches a home price of $1,050,000, so income is what limits you here, not savings.

An estimate, not an approval. A real approval depends on your credit, how your income is documented, the property itself and the lender's own ratios, which this calculator lets you change under Advanced. Property tax and heat are estimates; a condo fee and an acreage's well and septic can both move the answer. Qualifying uses the stress test under OSFI guideline B-20.
