How do I calculate my debt-to-income ratio for loan approval?

Learn how to compute your debt-to-income ratio, a critical factor in determining your eligibility for various types of loans.


Calculating your debt-to-income ratio (DTI) is an important step when applying for a loan, as it helps lenders assess your ability to manage additional debt. Your DTI ratio is a measure of your monthly debt obligations relative to your gross monthly income. Lenders use this ratio to determine whether you can afford the loan payments you're applying for. Here's how to calculate your DTI:

Step 1: Calculate Your Monthly Debt Payments

Gather all your monthly debt obligations, including but not limited to:

  1. Mortgage or Rent Payment: Include the monthly cost of your mortgage or rent, including principal, interest, property taxes, and homeowner's insurance (if applicable).

  2. Credit Card Payments: Add up the minimum monthly payments on all your credit cards.

  3. Car Loan Payments: Include the monthly payments on any auto loans.

  4. Student Loan Payments: Include the monthly payments on all your student loans.

  5. Personal Loans: Include the monthly payments on any personal loans you may have.

  6. Other Loans: If you have any other loans, such as payday loans or installment loans, include their monthly payments.

  7. Child Support or Alimony: If you pay child support or alimony, include these payments.

Step 2: Calculate Your Gross Monthly Income

Your gross monthly income is your total income before taxes and other deductions. Include all sources of income, such as:

  1. Salary or Wages: Your regular paycheck from your employer.

  2. Rental Income: If you have rental properties, include the rental income you receive.

  3. Self-Employment Income: If you're self-employed, use your average monthly income after expenses.

  4. Additional Income Sources: Include income from investments, alimony received, child support, and any other sources of income.

Step 3: Calculate Your DTI Ratio

Divide your total monthly debt payments (from Step 1) by your gross monthly income (from Step 2), and then multiply the result by 100 to express the ratio as a percentage:

DTI Ratio=(Total Monthly Debt PaymentsGross Monthly Income)×100\text{DTI Ratio} = \left( \frac{\text{Total Monthly Debt Payments}}{\text{Gross Monthly Income}} \right) \times 100

For example, if your total monthly debt payments amount to $1,500, and your gross monthly income is $5,000, your DTI ratio would be:

DTI Ratio=($1,500$5,000)×100=30%\text{DTI Ratio} = \left( \frac{\$1,500}{\$5,000} \right) \times 100 = 30\%

Step 4: Interpret Your DTI Ratio

Your DTI ratio is expressed as a percentage. Lenders typically have specific DTI ratio requirements for loan approval, but here's a general guideline:

  • Lower DTI Ratio (Under 36%): A lower DTI ratio indicates that you have a lower level of debt relative to your income. Lenders generally view lower DTI ratios more favorably, as they suggest you have more financial flexibility to handle additional debt.

  • Higher DTI Ratio (Over 36%): A higher DTI ratio indicates that a significant portion of your income goes toward debt payments. Lenders may be more cautious and may require additional documentation or offer less favorable terms if your DTI ratio is high.

Keep in mind that different types of loans and lenders may have varying DTI ratio requirements, so it's essential to check with the specific lender you're applying to for their guidelines. Additionally, it's often a good practice to work on lowering your DTI ratio by paying down existing debts before applying for new loans, as this can improve your chances of loan approval and potentially lead to more favorable terms.

Calculating Your Debt-to-Income Ratio for Loan Eligibility.

To calculate your debt-to-income ratio (DTI), you will need to add up all of your monthly debt payments and divide them by your gross monthly income. Your gross monthly income is the amount of money you earn before taxes and other deductions are taken out.

To calculate your monthly debt payments, include all of your recurring monthly debts, such as:

  • Mortgage or rent
  • Credit card payments
  • Student loan payments
  • Auto loan payments
  • Personal loan payments
  • Alimony or child support payments

Once you have added up all of your monthly debt payments, divide this number by your gross monthly income to get your DTI. For example, if your monthly debt payments are $1,000 and your gross monthly income is $5,000, then your DTI is 20%.

DTI = (Monthly debt payments) / (Gross monthly income)

Lenders typically use your DTI to determine your eligibility for a loan and to set your interest rate. A lower DTI means that you have less debt relative to your income and are therefore a less risky borrower.

Generally speaking, lenders prefer borrowers with a DTI of 36% or less. However, some lenders may be willing to approve borrowers with a DTI of up to 43%. If your DTI is higher than 43%, you may have difficulty getting approved for a loan or you may be offered a higher interest rate.

If you are concerned about your DTI, there are a few things you can do to improve it:

  • Pay down debt: The more debt you can pay down, the lower your DTI will be.
  • Increase your income: If you can increase your income, your DTI will automatically improve.
  • Consider a co-signer: If you have a low DTI, you may be able to qualify for a loan with the help of a co-signer. A co-signer is someone who agrees to repay the loan if you default.

If you are considering applying for a loan, it is important to talk to a financial advisor to discuss your individual situation and to get help improving your DTI.
