Debt-to-Income (DTI) Ratio Calculator*

What is a debt-to-income (DTI) ratio?

At a glance

Your debt-to-income (DTI) ratio compares your monthly debt payments to your gross monthly income (before taxes and deductions, like employer-provided insurance premiums). It is expressed as a percentage and helps illustrate how much of your income goes toward debt.

DTI = Total monthly debt payments ÷ Gross monthly income

For example, if you pay $1,500 toward debt each month and earn $5,000 before taxes, your estimated DTI is 30%.

What DTI represents

Your DTI provides a snapshot of your current financial obligations relative to your income.

It may help you:

• Understand how much of your income is allocated to debt
• Evaluate your capacity to take on additional financial obligations
• Track changes in your financial profile over time

DTI focuses on recurring debt payments and generally does not include everyday expenses such as groceries, utilities or savings. However, note that DTI generally includes rent payments, as those are considered housing-related debts.

How DTI is commonly used

DTI is a commonly used metric in lending. Financial institutions may consider your DTI, along with other factors, when evaluating applications for credit products such as mortgages, personal loans or credit cards.

A lower DTI may indicate that a smaller portion of your income is committed to debt, while a higher DTI may indicate a larger share is already allocated. In other words, a lower DTI may signal you are able to take on more debt while a higher DTI may indicate that you may already have a high debt burden.

However, DTI is only one factor and does not, by itself, determine approval, rates or terms.

Important to keep in mind

• DTI is an estimate based on the information you provide
• Definitions of income and debt as factors of your DTI may vary by lender
• Lenders may calculate DTI differently depending on the loan type

Why is DTI important?

DTI may be a factor that lenders review when you apply for credit. It helps show how much of your income may already be committed to existing obligations.

In general, DTI may help lenders evaluate:

• How much of your income is already committed to debt
• Whether your budget may have room for additional payments
• How your current debt compares to your income

How is DTI calculated?

Your DTI ratio compares your total monthly debt payments to your gross monthly income (before taxes and other deductions).

Income may include

• Wages or salary before taxes
• Self-employment or business income
• Rental income
• Retirement income
• Investment income
• Social Security benefits
• Dividends from investments

Monthly debt payments may include

• Housing costs such as rent or mortgage payments
• Property taxes or HOA fees, if applicable
• Credit card payments
• HELOC or other revolving debt payments
• Loan payments, including student, auto, personal or other loans
• Other obligations, such as child or spousal support

To estimate your DTI, add your total monthly debt payments and divide that amount by your gross monthly income.

Example

• Gross monthly income: $9,000
• Monthly debt payments:
• Mortgage: $2,850
• Property tax: $150
• Credit cards: $300
• Auto loan: $400

Total monthly debt = $3,700

Estimated DTI = $3,700 ÷ $9,000 = 41.1%

This DTI calculator does the math for you based on the numbers you enter.

How to use the DTI calculator

Getting started with the calculator takes just a few steps:

Step 1: Enter your income

Simply enter your total monthly income before taxes into the top left box.

Step 2: Enter your monthly expenses

You can enter your debt in one of two ways:

Option 1: Quick total

Enter one total amount for all of your total monthly debt payments.

Option 2: Detailed breakdown

Use the dropdown to add each type of debt. Here are some examples:

• Housing: Rent, mortgage, property tax, HOA
• Revolving Debt: Credit cards or HELOC
• Installment Loans: Student, auto, personal or other loans
• Other obligations: Child support or spousal support
• Miscellaneous debts: Any other monthly debt payment you want to include

Using the detailed option may help you better understand where your monthly payments are going.

Step 3: View your results

Once your information is entered, the calculator displays your results with a color-coded DTI gauge and two views: DTI Ratio and Ratio Breakdown.

DTI Gauge

Our calculator gives you a color-coded gauge to help you generally understand where your ratio falls. Your current DTI is marked along a scale from lower to higher ranges. As your DTI increases, the indicator moves upward, showing how much of your income is committed to debt.

DTI Ratio tab

This gives you a quick snapshot of your debt-to-income ratio:

• Back-end DTI: The percentage of your income that goes toward all monthly debt payments
• Front-end DTI: The percentage of your income spent on housing costs only
• Total monthly income: Your estimated income before taxes and other deductions
• Total monthly debt: The combined total of all your debt payments

Ratio Breakdown tab

This view helps you visualize where your money is going:

• A donut chart showing your back-end DTI
• A breakdown of housing, debt and remaining income
• Insight into which categories make up the largest share of your payments

Explore Different Scenarios

You can adjust your income or debt inputs at any time to see how changes affect your results.

For example:

• Paying down credit cards lowers your back-end DTI
• Reducing housing costs lowers both front-end and back-end DTI
• Increasing income lowers your ratio across the board

This “what-if” approach helps you understand how financial decisions may impact your borrowing power or overall budget.

Limitations to keep in mind

A DTI calculator can be a helpful starting point, but it’s important to understand its limitations.

Results are estimates

Your results are based on the information you provide. Actual lender calculations and outcomes may differ.

Not all expenses are included

DTI focuses on debt payments. It usually does not include everyday expenses such as:

• Utilities
• Groceries
• Insurance
• Medical costs
• Child care
• Savings contributions
• Subscriptions

Lender criteria may vary

Different lenders and loan programs may define income and debt differently. They may also use different DTI ranges and calculation methods. For example, when evaluating a mortgage application, a lender may consider calculating your DTI using the projected monthly housing payment for the loan that you are applying for, rather than your current housing expenses, such as your rent.

If you're applying for a specific loan, contact your lender for details about how your DTI may be calculated.

DTI does not determine approval

Your DTI alone does not decide whether you qualify for credit. Lenders may also consider your credit history, credit score, income, assets and other information.

Your situation is unique

This calculator provides general educational information. It is not a substitute for personalized financial, legal or tax advice.

When is a DTI calculator most useful?

A DTI calculator can be helpful at several points in your financial journey, especially when you’re planning for or evaluating new credit.

For example, before applying for a mortgage, auto loan or personal loan, estimating your DTI can help you understand how your debt-to-income ratio may be considered as part of the application process. It can also be useful when reviewing your overall financial health, giving you a clearer picture of how much of your income is already going toward debt and whether adjustments may be needed.

If you're planning a major purchase, such as buying a home or financing a vehicle, checking your DTI can help you evaluate affordability and better understand how a new payment might fit into your budget. If you're working to reduce debt, a DTI calculator can help you evaluate how changes, such as paying down balances or increasing income, may affect your debt-to-income ratio. This can provide a clearer view of how your financial profile may evolve as your circumstances change.

You can also use the calculator to explore different scenarios by adjusting income or debt amounts, helping you see how potential changes could impact your financial flexibility.

How you can lower your DTI

Lowering your debt-to-income (DTI) ratio generally involves reducing monthly debt payments, increasing your income, or a combination of both. This may include paying down existing balances, avoiding new debt, or making additional payments when possible. Some individuals may also consider increasing income or exploring options such as refinancing or consolidating certain debts. Paying off smaller balances can also help reduce the number of monthly obligations.

Results will vary based on your financial situation. Some strategies may involve costs, fees, or other tradeoffs, so it’s important to evaluate your options carefully.

Take the next step

Your DTI is just one part of your financial picture. But, it can be an important one.
