Cmhc Ratio Calculator
The CMHC Ratio, also known as the Gross Debt Service (GDS) ratio, is an important financial metric used by the Canada Mortgage and Housing Corporation (CMHC) to determine a borrower’s housing affordability. This ratio is critical for mortgage approval, especially in Canada, and plays a central role in home buying decisions.
If you’re applying for a mortgage or planning to buy a home, understanding and calculating your CMHC Ratio is vital. In this guide, we’ll explore what the CMHC Ratio is, how to calculate it, and how to use our calculator to simplify the process.
Formula
The CMHC Ratio is calculated using the formula:
CMHC Ratio = (Total Monthly Housing Costs / Gross Monthly Income) × 100
Where:
- Total Monthly Housing Costs include mortgage payments, property taxes, heating costs, and 50% of condo fees if applicable.
- Gross Monthly Income is the total income before deductions like taxes and insurance.
How to Use the Calculator
Using our CMHC Ratio Calculator is straightforward:
- Enter your Total Monthly Housing Costs: Include mortgage, property taxes, heating, and half of condo fees.
- Input your Gross Monthly Income: Use your income before taxes or other deductions.
- Click the “Calculate” button: Instantly see your CMHC Ratio displayed as a percentage.
The calculator provides a quick and reliable way to assess your mortgage eligibility according to CMHC guidelines.
Example
Suppose:
- Your total monthly housing costs are $1,800.
- Your gross monthly income is $6,000.
Using the formula:
CMHC Ratio = (1,800 / 6,000) × 100 = 30%
A 30% CMHC Ratio is typically acceptable by most lenders in Canada, as it falls under the 32% limit recommended by CMHC.
