How to Calculate Your Debt-to-Income Ratio

Understanding your financial health is crucial for making informed decisions about your money. One of the key indicators of financial stability is the Debt-to-Income (DTI) ratio. This metric is used by lenders, such as Cashin Mortgages, to evaluate your ability to manage monthly payments and repay debts. In this blog, we will explore what the DTI ratio is, why it is important, how to calculate it, and what steps you can take to improve it.

What is the Debt-to-Income Ratio?

The Debt-to-Income (DTI) ratio is a financial metric that compares your monthly debt payments to your monthly gross income. It is expressed as a percentage and helps lenders assess your ability to manage your debt load. There are two types of DTI ratios: the front-end ratio and the back-end ratio.

Front-End Ratio

The front-end ratio, also known as the housing ratio, considers only your housing-related expenses. This includes your mortgage or rent payments, property taxes, homeowners insurance, and any homeowners association (HOA) fees.

Back-End Ratio

The back-end ratio, on the other hand, includes all your monthly debt obligations. This encompasses housing costs as well as credit card payments, car loans, student loans, and any other debt payments you have.

Why is the DTI Ratio Important?

The DTI ratio is a critical measure for both borrowers and lenders. For lenders, it is an essential tool for assessing risk. A high DTI ratio indicates that a significant portion of your income is tied up in debt payments, suggesting that you might struggle to manage additional debt. Conversely, a low DTI ratio suggests better financial health and a greater ability to handle new debt.


For borrowers, understanding your DTI ratio can provide valuable insights into your financial situation. It helps you evaluate whether you can afford to take on new debt, such as a mortgage or a car loan, and can also highlight areas where you might need to reduce expenses or pay down debt.

How to Calculate Your DTI Ratio

Calculating your DTI ratio is a straightforward process. Here are the steps to follow:

Calculate Your Monthly Gross Income

Your gross income is your total income before taxes and other deductions. This includes your salary, bonuses, rental income, and any other sources of income.

Calculate Your Monthly Debt Payments

Add up all your monthly debt payments. This includes your mortgage or rent, car loan payments, credit card payments, student loans, and any other recurring debt obligations.

Divide Your Total Monthly Debt by Your Gross Monthly Income

Use the formula: 


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

Example Calculation

Let’s consider an example to illustrate the calculation. Assume you have the following monthly expenses and income:


  • Mortgage Payment: $1,200
  • Car Loan Payment: $300
  • Credit Card Payments: $150
  • Student Loan Payments: $250
  • Gross Monthly Income: $5,000


First, calculate your total monthly debt payments:


Total Monthly Debt Payments=1,200+300+150+250=1,900


Next, use the DTI formula:


DTI Ratio=(5,000/1,900)×100=38%


In this example, the DTI ratio is 38%, indicating that 38% of your gross monthly income goes towards debt payments.

Interpreting Your DTI Ratio

Interpreting your DTI ratio is crucial for understanding your financial health. Here are some general guidelines:

  • DTI Ratio Below 20%

This is considered excellent. You have a manageable debt load and are likely in a strong position to take on additional debt if needed.

  • DTI Ratio Between 20% and 36%

This range is considered good. Most lenders view this as an acceptable level of debt and you are likely to qualify for loans with favorable terms.

  • DTI Ratio Between 36% and 43%

This range is acceptable but may raise some concerns. You may still qualify for loans, but lenders might offer less favorable terms or higher interest rates.

  • DTI Ratio Above 43%

This is a red flag. Lenders view this as a high-risk level of debt, and you may have difficulty qualifying for loans. It indicates that you may be overextended and should consider reducing your debt load.

Improving Your DTI Ratio

If your DTI ratio is higher than desired, there are several strategies you can use to improve it:

  • Increase Your Income

Consider ways to boost your income, such as taking on a part-time job, freelancing, or seeking a promotion at work.

  • Reduce Your Debt

Focus on paying down your existing debts. Start with high-interest debts, such as credit cards, to reduce your overall debt burden more quickly.

  • Refinance Your Loans

Refinancing can lower your monthly payments by securing a lower interest rate or extending the loan term. This can reduce your overall debt payments and improve your DTI ratio.

  • Limit New Debt

Avoid taking on new debt until your DTI ratio is at a more manageable level. This includes avoiding new credit card charges and delaying major purchases.


  • Create a Budget

Establish a budget to manage your expenses better. Track your spending and identify areas where you can cut back to free up more money for debt payments.


Understanding and managing your Debt-to-Income (DTI) ratio is essential for maintaining financial health and securing favorable loan terms. By calculating your DTI ratio and taking steps to improve it, you can ensure that your debt remains manageable and that you are in a strong position to achieve your financial goals.
