Debt-to-Income (DTI) Ratio: What It Is and Why It Matters

Understanding your financial health is important for making informed decisions about loans, mortgages, and long-term investments. One of the most critical indicators to identify the health of your financial situation is the Debt-to-Income (DTI) ratio. Whether you’re buying a home, refinancing a mortgage, or applying for a personal loan, lenders use your DTI ratio to assess your ability to manage debt.

In this comprehensive guide, we’ll walk you through what the debt-to-income ratio is, why it’s important, and how to calculate it.

What Is a Debt-to-Income Ratio?

A debt-to-income (DTI) ratio is a financial measurement used to compare the amount of debt you owe each month to the amount of income you earn. It’s expressed as a percentage and helps lenders determine how well you’re managing your existing debt and whether you can afford to take on any more loans.

How to Calculate Debt-to-Income Ratio

The debt-to-income (DTI) ratio is a simple, yet powerful calculation used by lenders to evaluate your ability to manage monthly debt payments. In essence, it compares your total monthly debt payments to your gross monthly income.

Here’s how it’s calculated:

DTI Ratio = (Gross Monthly Income Total/ Monthly Debt Payments​) ×100

For example, if your total monthly debt payments (including mortgages, car loans, and credit card payments) amount to $2,000, and your gross monthly income is $5,000, your DTI ratio would be:

(5,000/ 2,000​) ×100=40%

This means that 40% of your gross income goes toward paying off debt each month. The DTI ratio helps lenders assess whether you can take on additional debt without risking financial distress.

Why Lenders Care About Debt-to-Income Ratio?

Lenders view the DTI ratio as a key indicator to check the financial stability of homeowners before approving additional loan or mortgage. There are two types of DTI ratio:

Low DTI = Less Risk Borrowers

A lower DTI ratio suggests that you have more financial flexibility and a healthier financial situation. It’s a positive sign for lenders to approve you for better interest rates because it shows that you are more likely to manage additional debt, such as a mortgage, without financial strain.

High DTI = Higher Financial Stress

On the other hand, a high DTI ratio indicates that a significant portion of your income is already committed to debt repayment, which could make it challenging to afford additional payments. For lenders, a high DTI ratio raises red flags about your ability to meet new financial obligations.

How Lenders Use Debt-to-Income Ratio

Lenders use the debt-to-income ratio to assess risk. The higher your DTI ratio, the riskier you appear to a lender. Here’s how it plays a role in specific types of lending:

  1. Mortgage Approval

When applying for a mortgage in Canada, your DTI ratio is one of the key factors lenders will evaluate. It helps them assess your ability to manage monthly mortgage payments in addition to your existing debt. A lower DTI ratio indicates that your earnings are more than your debt and you are less likely to default on the mortgage, while a higher DTI ratio signals higher financial risk.

  1. Personal Loans

Personal loan lenders also pay close attention to your DTI ratio. While they may allow slightly higher ratios than mortgage lenders, a high DTI can still result in less favorable terms or a loan denial.

  1. Credit Cards

Credit card companies may not check your DTI ratio directly, but your credit utilization—how much of your available credit you’re using—can indirectly affect your DTI. High balances on revolving credit lines can negatively impact your credit score, which in turn affects your DTI ratio.

How Does Your Debt-to-Income Ratio Impact Mortgage Approval?

Your DTI ratio can significantly impact your chances of securing a mortgage. Lenders use DTI as a benchmark to assess your ability to handle mortgage payments in addition to your current debt obligations.

Good vs. Bad DTI Ratios

  • DTI under 35%: This is considered ideal and increases your chances of mortgage approval with favorable terms.
  • DTI between 36%-42%: Manageable, but some lenders may offer stricter terms.
  • DTI above 43%: This is considered high risk, and many lenders will hesitate to offer a mortgage unless you can reduce your debt load.

For homeowners with a high DTI, traditional lenders may deny mortgage applications. However, turnedaway.ca specializes in helping individuals in these situations by providing flexible mortgage solutions tailored to their needs.

What Is a Good Debt-to-Income Ratio?

  1. Gross Debt Service (GDS) Ratio

The Gross Debt Service ratio measures the portion of a borrower’s income that is required to cover housing-related costs, such as mortgage payments, property taxes, heating, and 50% of condo fees (if applicable).

GDS Formula = Housing Costs/ Gross Income×100

Ideal GDS: In Canada, lenders typically prefer a GDS ratio of 32% or less, meaning your housing costs should not exceed 32% of your gross income.

  1. Total Debt Service (TDS) Ratio

The Total Debt Service ratio expands upon the GDS ratio by including all other debt obligations in addition to housing costs, such as car loans, credit card payments, personal loans, and any other monthly debt repayments.

TDS Formula = Total Debt Payments (housing + other debts)/ Gross Income×100

Ideal TDS: Lenders prefer a TDS ratio of 40-42% or less. This means that your total debt obligations, including housing costs, should not exceed 42% of your gross income.

Key Differences:

  • GDS focuses only on housing costs, while TDS includes all monthly debt obligations.
  • Both ratios are crucial for lenders to ensure that borrowers can manage their debt without overstretching their financial resources.

Anything above these thresholds may result in rejection of your loan application or approval but with higher interest rates. A healthy DTI ratio demonstrates that you’re in control of your finances and capable of managing additional debt, giving lenders confidence in your ability to pay back your mortgage.

Why Debt-to-Income Ratio Matters for Canadian Homeowners

Your debt-to-income ratio is an essential metric for both personal finance and creditworthiness. Here’s why it matters:

  1. Loan Approval

When you apply for a mortgage, auto loan, or any other type of credit, lenders will typically assess your debt-to-income ratio to gauge your ability to repay the loan. If you have low DTI ratio then you’re more likely to get approved for credit, while a higher ratio can lead to rejection or unfavorable loan terms.

  1. Interest Rates

Even if you qualify for a loan, a high DTI ratio can result in higher interest rates. Lenders see you as a high-risk borrower, meaning you could default on your loan. To offset this risk, they may offer you a high interest loa option.

  1. Financial Health

For individuals, the debt-to-income ratio indicates overall sign of healthier financial state. If too much of your income is going toward debt, it can limit your ability to save, invest, and cover unexpected expenses.

Debt-to-Income Ratio in Canada

The concept of debt-to-income ratio is crucial in Canada, especially given the country’s rising household debt levels. According to Statistics Canada, household debt as a percentage of disposable income has been steadily increasing, making it more important than ever for Canadians to manage their DTI ratios responsibly.

How to Improve Your Debt-to-Income Ratio

Improving your debt-to-income ratio can help you secure better loan terms, lower interest rates, and improve your overall financial situation. Here are a few steps you can take to reduce your DTI ratio:

  1. Pay Off High-Interest Debt First

High-interest debts, like credit card balances, can quickly inflate your monthly payments. By prioritizing paying down these debts, you can lower your overall monthly debt load and improve your DTI ratio.

  1. Increase Your Income

Increasing your gross monthly income is one way to lower your DTI ratio. Whether it’s negotiating a raise, picking up a side hustle, or finding other sources of income, a higher income can balance out your debt obligations.

  1. Consolidate Your Debt

Debt consolidation can be an effective strategy to manage multiple high-interest debts. By consolidating several debts into one loan with a lower interest rate, you can reduce your monthly payments to improve your DTI ratio.

  1. Reevaluate Your Budget

Creating a detailed budget can help you spot areas where you can cut back on unnecessary expenses. The money saved can be redirected toward paying off debts, lowering your DTI ratio over time.

  1. Avoid New Debt

Until you’ve lowered your DTI ratio, it’s wise to avoid taking on new debt. This includes avoiding large purchases on credit and delaying loan applications.

At Turnedaway.ca, we offer debt consolidation loans that can help lower your DTI, making it easier to qualify for a mortgage or other loans. By consolidating high-interest debt, you can free up more of your income and reduce financial stress.
