How Much Income Do You Need to Qualify for a Mortgage?

Found a home you love and wondering if you can qualify? This calculator works the equation in reverse — enter the purchase price, down payment, rate, and your existing monthly debts to find out what gross annual income you need to get approved.

How Lenders Assess Income

Canadian lenders use two key ratios to determine whether your income is sufficient to support a mortgage:

Gross Debt Service (GDS) Ratio — Your principal, interest, property tax, heat, and 50% of condo fees must stay within 39% of gross monthly income.

Total Debt Service (TDS) Ratio — The same housing costs, plus all other monthly debt payments (car loans, credit lines, credit cards), must stay within 44% of gross monthly income.

What Counts as Income?

Lenders consider employment income, self-employment income (typically a 2-year average), rental income, pension and investment income, and in some cases child support or alimony. Not all income types are treated equally — a mortgage broker can help you present your income in the most favourable way for each lender.

The Stress Test Factor

Remember that lenders qualify you at the higher of your contract rate plus 2%, or 5.25%. If your contract rate is 4.5%, you’re qualifying at 6.5% — which means the income requirement is higher than many buyers expect.

What the Calculator Shows You

This tool gives you an income benchmark for any purchase price. If the number is higher than your current income, a mortgage broker can explore options: adding a co-borrower, choosing a different amortization, or identifying lenders with more flexible guidelines.
