Last updated: April 7, 2025

Calculating your mortgage debt-to-income ratio is a crucial step in the home buying process. Understanding your DTI helps you determine how much you can afford and increases your chances of mortgage approval. With a reliable mortgage DTI calculator, you gain clear insights into your financial standing.

Using a DTI calculator empowers you to make informed decisions about your housing budget. By evaluating your income against your debts, you can identify the best mortgage options that fit your lifestyle. Stay confident and take control of your home financing journey with the right tools at your fingertips.

What Is A Debt-To-Income (DTI) Ratio?

A debt-to-income (DTI) ratio measures your monthly debt payments against your gross monthly income. Calculating your DTI evaluates your financial capacity and assists lenders in determining your loan eligibility.

How to Calculate Your DTI Ratio

  1. List Monthly Debt Payments: Include mortgage or rent, car loans, student loans, credit card payments, and other recurring debts.
  2. Determine Gross Monthly Income: Sum all income sources before taxes, such as salary, bonuses, and other earnings.
  3. Compute the DTI Ratio: Divide total monthly debts by gross monthly income and multiply by 100 to obtain a percentage.
Component Amount ($)
Total Monthly Debts 2,500
Gross Monthly Income 7,500
DTI Ratio 33%

A DTI ratio indicates better financial health and enhances your chances of mortgage approval if it is below 36%.

Why Use A Mortgage DTI Calculator?

  1. Determine Affordability: Calculate the maximum mortgage amount by comparing your monthly debts to your gross income.
  2. Enhance Approval Chances: Present an accurate DTI ratio to increase the likelihood of securing a mortgage with favorable terms.
  3. Plan Your Budget: Align your housing expenses with your income to maintain financial stability.
  4. Identify Debt Levels: Assess current debts such as credit card balances, student loans, and car payments to understand their impact on eligibility.
  5. Compare Loan Options: Evaluate different mortgage products based on their effect on your overall DTI ratio.

How To Calculate Your DTI Ratio

Calculating your Debt-to-Income (DTI) ratio involves a systematic approach to assess your financial health. Follow these steps to determine your DTI accurately.

Gather Your Financial Information

Collect all monthly debt obligations including mortgage payments, car loans, student loans, credit card payments, and any other recurring debts. Ensure each debt amount is up-to-date to maintain calculation accuracy.

Calculate Your Monthly Debt Payments

Sum your total monthly debt payments by adding each individual debt listed. For example, if you have a $1,200 mortgage, $300 car loan, and $150 credit card payment, your total monthly debt payments equal $1,650.

Determine Your Gross Monthly Income

Identify your total gross monthly income before taxes and deductions. Include salary, bonuses, rental income, and any other consistent income sources. For instance, a salary of $4,000 and rental income of $500 result in a gross monthly income of $4,500.

Compute Your DTI Ratio

Divide your total monthly debt payments by your gross monthly income and multiply by 100 to obtain your DTI ratio percentage. Using the previous examples: ($1,650 ÷ $4,500) × 100 equals a DTI ratio of 36.67%.
