GDS / TDS calculator
See how lenders assess your borrowing capacity. For best rates, GDS should be ≤ 39%; TDS ≤ 44%.
GDS = housing costs ÷ gross monthly income. TDS = (housing costs + other debts) ÷ gross monthly income. Condo fees counted at 50%. Lender limits vary; 39% GDS and 44% TDS are standard CMHC guidelines.
Affordability calculator
Find out the maximum purchase price you may qualify for based on current rates and stress test rules.
This is an estimate based on current best available rates and CMHC stress test rules. Speak to a Frank advisor for a precise qualification.
Based on the information provided, a mortgage qualification could not be calculated. This may be due to income-to-debt ratios exceeding lender guidelines or a very low down payment. Consider speaking with a Frank advisor to explore your options.
