Debt-to-income ratio: Definition, calculation, and interpretation
The debt-to-income ratio (DTI) is one of the most important financial tools used by banks, private lenders, and investors to assess your borrowing capacity. It shows the portion of your income that goes toward repaying your debts and directly impacts the approval, or refusal, of a mortgage, loan, or refinancing application.
While traditional banks rely heavily on this number, at Financière Victoria, we look beyond it.
So, how exactly is it calculated? What’s considered a good debt-to-income ratio in Quebec? And most importantly, how can you tell if your current situation looks healthy to lenders? Let’s break it down.
What Is the Debt-to-Income Ratio?
The debt-to-income ratio (DTI) is a percentage that shows how much of your monthly income goes toward repaying your debts. The higher your ratio, the riskier you appear to lenders.
For a mortgage, a healthy debt-to-income ratio is typically below 40%. This means that all your monthly debts, mortgage payments, car loans, credit cards, and other obligations, should not exceed 40% of your gross monthly income. Banks tend to be strict about this threshold.
However, private lenders see things differently.
A high debt-to-income ratio isn’t always a deal-breaker. What matters most is the value of your property (or your home equity), the size of your down payment, and your repayment strategy.
For example, a private mortgage can still be approved even with a DTI of 50% or higher, as long as there’s enough equity and a solid plan in place.
At Financière Victoria, we evaluate every application as a whole—not just a number.
If your ratio is temporarily high but you have a strong down payment or valuable property as collateral, we can build a custom financing solution with terms that fit your situation.
How to calculate your debt-to-income ratio in real estate
Whether you’re applying for a mortgage to buy a home or investing in a rental property, understanding how to calculate your debt-to-income ratio (DTI) is an essential step.
Here’s how it works:
Your debt-to-income ratio represents the percentage of your gross monthly income that goes toward repaying your debts. It’s calculated using the following formula:
Debt-to-Income Ratio (%) = (Total Monthly Debts / Gross Monthly Income) × 100
The debts usually included in this calculation are:
- Projected mortgage payment (principal + interest) or rent
- Property taxes and home insurance fees
- Credit card balances to be repaid
- Payments on existing loans (auto, personal, student, etc.)
- Recurring financial obligations (e.g., alimony or child support)
Your gross monthly income includes:
- Salary before taxes
- Rental income
- Regular bonuses or commissions
- Declared income from secondary activities
Example of a debt-to-income ratio calculation
To better understand how to use the debt-to-income ratio formula, let’s look at a concrete example.
Imagine the following situation:
Gross monthly income: $5,000
Monthly debts:
- Mortgage payment: $1,200
- Car loan: $400
- Minimum credit card payment: $150
- Student loan: $250
Total monthly debts = $1,200 + $400 + $150 + $250 = $2,000
Applying the formula:
(2,000 ÷ 5,000) × 100 = 40%
Result: The debt-to-income ratio is 40%.
How to Interpret a Debt-to-Income Ratio in Real Estate
In real estate, the debt-to-income ratio (DTI) is a key indicator used to assess your borrowing capacity. Here’s how it’s generally interpreted:
| Debt-to-Income Ratio | Interpretation |
|---|---|
| Below 30% | Excellent borrowing capacity. Quick access to financing, often at preferred rates. |
| 30 – 40 % | Typically considered acceptable, especially with a solid down payment. |
| 40 – 45 % | Higher risk, but financing may still be possible depending on available equity. |
| 45 % and above | Less common, but possible with a detailed evaluation and a customized financing structure. |
In short, to maximize your chances of approval, aim for a DTI below 35% and adjust your project or debts if needed before applying for a loan. Once you exceed 43–44%, traditional banks become much stricter unless additional guarantees are provided.
A high ratio isn’t necessarily a deal-breaker. At Financière Victoria, we assess every application based on your overall situation and real estate goals: not just the numbers.

How to improve your debt-to-income ratio
- Reduce existing debts: Focus on paying down high-interest debts first.
- Increase your income: Look for additional income sources to improve your debt-to-income balance.
- Avoid new debts: Limit extra financial commitments until your ratio reaches a healthier level.
Why you should monitor your debt-to-income ratio before applying for a loan
Here are the concrete benefits of maintaining a healthy ratio:
- Strengthen your application: a solid DTI inspires confidence and shows lenders that you’re financially responsible.
- Negotiate better terms: benefit from lower interest rates and more flexible repayment options.
- Prepare for the unexpected: having financial breathing room helps reduce risk in case of unforeseen expenses.
- Stay within critical limits: most banks aim for a total debt service ratio (TDS) under 40%.
