Payment Calculator

How this works: Canadian lenders use two key ratios to determine how much you can borrow:

  • GDS (Gross Debt Service): Housing costs must be 39% or less of gross income
  • TDS (Total Debt Service): All debts must be 44% or less of gross income

Lenders also apply the stress test — qualifying you at the higher of your rate + 2% or 5.25%.
