The CMHC Ratio Calculator is an essential tool used by homebuyers, mortgage brokers, and lenders in Canada to evaluate mortgage affordability. Specifically, it calculates the Gross Debt Service (GDS) ratio, which is one of the key metrics used by the Canada Mortgage and Housing Corporation (CMHC) to determine if a borrower qualifies for a mortgage loan.
The GDS ratio helps determine how much of your monthly income is going toward housing expenses. If the percentage is too high, your loan application may be rejected, or you may need to lower your borrowing amount. This calculator provides a quick and easy way to check your eligibility before applying for a home loan.
Formula
The formula is:
CMHC Ratio = Monthly Housing Costs ÷ Gross Monthly Income × 100
Where:
- Monthly Housing Costs include mortgage principal and interest, property taxes, heating costs, and 50% of condo fees (if applicable).
- Gross Monthly Income is your total income before taxes and deductions.
The result is a percentage representing your GDS ratio.
How to Use the CMHC Ratio Calculator
- Monthly Housing Costs ($):
Enter the total monthly housing expenses, including mortgage payments, property taxes, heating bills, and half of condo fees (if applicable). - Gross Monthly Income ($):
Input your total gross income per month (before any taxes or deductions). - Click the Calculate button.
The calculator will instantly display your CMHC GDS ratio as a percentage. This helps you understand how lenders will evaluate your mortgage affordability.
Example Calculation
Suppose:
- Monthly Housing Costs = $1,800
- Gross Monthly Income = $5,500
Now apply the formula:
CMHC Ratio = (1,800 ÷ 5,500) × 100 = 32.73%
Result:
Your CMHC GDS ratio is 32.73%, which is under the CMHC’s typical threshold of 35%—indicating that you may be eligible for a mortgage.
