Debt-to-Income Ratio Calculator: What Lenders Actually See

Your debt-to-income ratio (DTI) is one of the first numbers a lender looks at when you apply for a mortgage, car loan, or personal line of credit. It tells them how much of your gross monthly income is already committed to debt payments. Most people do not know theirs until they are sitting across from a bank manager. Calculate it now instead.

Canadian mortgage lenders use two DTI variants: GDS (Gross Debt Service ratio) which includes only housing costs, and TDS (Total Debt Service ratio) which includes all debt payments. CMHC guidelines cap GDS at 39% and TDS at 44% for insured mortgages. If your DTI is above 36%, the fastest way to reduce it is to pay down revolving debt (credit cards) since they have the highest minimum payments relative to balance.
