While applying for a loan, lenders take into consideration several factors to ensure that you are a responsible borrower who can comfortably repay the debt. Lenders will only lend you money when they know you can repay it, but how can they be sure? This is where the debt-to-income (DTI) ratio comes into play.
It’s a factor that lenders consider to evaluate your repayment abilities, and understanding it can be helpful for your financial situation.
Read on to understand what the debt-to-income ratio is, its importance, and how to calculate it.
What is your debt-to-income (DTI) ratio?
The debt-to-income ratio (DTI) is a financial metric that compares an individual’s monthly debt payments to their total monthly income. Lenders typically use it to evaluate a borrower’s ability to manage monthly payments and repay debt.
A lower DTI ratio indicates a healthier balance between debt and income, indicating that the borrower is more likely to manage their debt payments effectively.
Conversely, a higher DTI ratio may indicate that the borrower has too much debt relative to his income and may have difficulty managing his liabilities. Generally, lenders prefer a DTI ratio of 36% or less.
The importance of the debt-to-income ratio
The debt-to-income (DTI) ratio is important for several reasons:
Lending decisions
Lenders use the DTI ratio to evaluate a borrower’s ability to manage monthly payments and repay debt. It is an important factor in the approval process for mortgages, auto loans, personal loans, and credit cards.
Interest rates and loan terms
DTI is an important factor in determining loan terms. Borrowers with lower DTI ratios are typically offered better interest rates and more favorable loan terms because they are viewed as less likely to default on their loans. Conversely, a higher DTI ratio can lead to higher interest rates and less favorable loan terms due to increased risk to the lender.
Financial health index
The DTI ratio is a good indicator of an individual’s financial health. It helps individuals understand their debt levels compared to their income and assess when they are drowning in debt.
Budget and planning
By calculating and understanding their DTI ratio, individuals can create more realistic budgets and financial plans. This helps them recognize what portion of their income goes toward paying off debt and allows them to plan to pay off their debt sooner, which can subsequently reduce their debt over time.
Meet lender requirements
Lenders typically prefer a DTI ratio of 36% or less for various types of loans.
Risk management
For lenders, the DTI ratio is a risk management tool. It helps them evaluate the likelihood of loan repayment and reduce the risk of default.
How is the debt-to-income ratio calculated?
The debt-to-income ratio (DTI) is calculated by dividing an individual’s total monthly debt payments by their total monthly income and multiplying the result by 100 to get a percentage.
Here is a step-by-step explanation of how to calculate it:
Step 1: Determine your total monthly debt payments
Include all recurring monthly debt obligations, such as mortgage or rent payments, car loan payments, student loan payments, credit card payments (usually the minimum payment due), personal loan payments, and any other debt payments.
Step 2: Calculate your gross monthly income
Gross monthly income is the total income earned before taxes and deductions. This includes salary or wages, bonuses, commissions, overtime pay (if regular), pensions and any other sources of regular income.
Step 3: Apply the formula
Use the following formula to calculate the DTI ratio:

Let us understand DTI calculation with an example:
Step 1: Determine your total monthly debt payments
- Home Loan Monthly Installment: INR 30,000
- Car loan monthly installment: INR 8,000
- Education Loan Monthly Installment: INR 4,000
- Minimum credit card payment: INR 3,000
Total monthly debt payments = ₹30,000 + ₹8,000 + ₹4,000 + ₹3,000 = ₹45,000
Step 2: Calculate your gross monthly income
- Salary: INR 1,20,000
- Reward: INR 10,000
Total monthly income = INR 1,20,000 + INR 10,000 = INR 1,30,000
Step 3: Calculate DTI ratio

DTI ratio ≈ 34.62%
This ratio indicates that 34.62% of an individual’s gross monthly income is used to cover debt payments, which can help lenders evaluate their creditworthiness.
What is a good debt to income ratio?
A good debt-to-income ratio indicates a manageable level of debt compared to income, indicating financial stability and the ability to handle additional borrowing when necessary.
Here are some general guidelines for what constitutes a good DTI ratio:
Lenders typically prefer a DTI ratio of 36% or less. You will likely be viewed as a low-risk borrower who manages debt responsibly.
Although this is not ideal, many lenders will still consider borrowers with a DTI ratio in this range, especially if other factors (such as a high credit score) are favorable.
Borrowers may still qualify for loans, but interest rates and terms may not be as favorable as those offered to individuals with lower DTI ratios.
A DTI ratio above 43% is generally considered high and may indicate that the borrower has too much debt. This can make it difficult to secure loans, and if approved, terms may include higher interest rates.
Borrowers with high DTI ratios may have difficulty managing monthly payments and are at greater risk of defaulting on their loans.
conclusion
Debt-to-income ratio is an important metric that plays an important role in lenders’ creditworthiness assessments and can help individuals determine their financial stability as well. A lower DTI ratio indicates a better balance between debt and income, which increases the likelihood of loan approval and favorable terms.
The DTI ratio is an important factor when it comes to approvals and setting conditions Personal loans. Lenders use this number to determine your ability to repay the loan while managing current liabilities. A lower DTI ratio enhances your chances of getting a personal loan with better interest rates and terms.
