Debt-to-Income Ratio Calculator

Your debt-to-income (DTI) ratio compares your total monthly debt payments to your gross monthly income. Lenders use this ratio to evaluate your ability to manage monthly payments and repay debts. A lower DTI ratio indicates better financial health and improves your chances of loan approval.

How to Use

1 Add up all your monthly debt payments including mortgage/rent, car loans, student loans, credit card minimums, and personal loans.

2 Enter your gross monthly income (before taxes).

3 The calculator will compute your DTI ratio and provide a rating.

4 A DTI below 36% is generally considered healthy for most loan applications.

Formula

Dti Ratio (monthly_debt_payments / monthly_income) × 100

Example: Mortgage Application Scenario

If you earn $6,000/month gross and have $1,800 in monthly debt payments (mortgage $1,200, car loan $400, credit cards $200), your DTI = ($1,800 / $6,000) × 100 = 30%. This is considered Good and would likely qualify for most mortgages.

Why It Matters

Your DTI ratio is one of the key factors lenders evaluate when you apply for a mortgage, auto loan, or other credit. A high DTI can limit your borrowing options and lead to higher interest rates. Maintaining a healthy DTI ratio is essential for financial stability and achieving major financial goals like buying a home.

Frequently Asked Questions

What is a good debt-to-income ratio?

Generally, a DTI of 35% or less is considered good. Below 36% is preferred by most lenders, while 36-49% is acceptable but may limit options. A DTI of 50% or higher is considered poor and may disqualify you from many loan programs.

What debts are included in DTI?

DTI includes all recurring monthly debt obligations: mortgage or rent payments, car loans, student loans, minimum credit card payments, personal loans, child support, and alimony. It does not typically include utilities, groceries, or insurance premiums.

Do lenders look at front-end or back-end DTI?

Lenders often look at both. Front-end DTI includes only housing-related costs (mortgage, taxes, insurance). Back-end DTI includes all monthly debt obligations. Most conventional mortgage guidelines prefer a back-end DTI of 36% or less, though some programs allow up to 43-50%.

How can I lower my DTI ratio?

You can lower your DTI by paying off debts (especially high-interest ones), increasing your income, avoiding taking on new debt, or refinancing existing loans to lower monthly payments. Focus on eliminating smaller debts first for quick wins.
