How It Works in Canada
Your DTI is simply your total monthly debt payments divided by your gross monthly income. Canadian lenders look at this same relationship through two lenses: the Gross Debt Service (GDS) ratio, which counts housing costs like the mortgage, property tax and heating, and the Total Debt Service (TDS) ratio, which adds all other debts on top. This calculator shows the all-debt, TDS-style figure.
Estimates only — not financial advice. Lenders apply their own cutoffs plus the mortgage stress test at qualification.
Frequently Asked Questions
What is a good debt-to-income ratio in Canada?
Lower is better. The calculator rates 28% and under as acceptable-or-better territory and flags anything over 43% as too high — most Canadian lenders become reluctant to approve mortgages at that level.
What counts as debt in the DTI?
Recurring debt payments: minimum loan and credit card payments, car payments, lines of credit, student loans and support payments. Utilities, groceries and subscriptions don't count.
What is the difference between GDS and TDS?
GDS (Gross Debt Service) covers housing costs only — mortgage, property tax and heating. TDS (Total Debt Service) adds every other debt on top. This calculator returns the TDS-style, all-debt figure.
Can I qualify for a mortgage with a high DTI?
It gets harder the higher you go. If your ratio is over 43%, paying down debts or increasing your down payment are the usual levers to bring it back into approvable range.
