What Is a Debt-to-Income Ratio?
A debt-to-income ratio, or DTI, compares your recurring monthly debt payments with your gross monthly income.
Gross monthly income means your income before taxes and other deductions.
The Consumer Financial Protection Bureau defines DTI as your monthly debt payments divided by your gross monthly income.
For example, suppose you have:
- Gross monthly income: $6,000
- Monthly debt payments: $2,000
Your DTI would be:
$2,000 ÷ $6,000 × 100 = 33.3%
This means about 33.3% of your gross monthly income is represented by the debts included in your calculation.
Debt-to-Income Ratio Formula
Use this formula to calculate DTI:
DTI formula
| Monthly obligation | Amount |
|---|---|
| Mortgage or rent | $1,400 |
| Auto loan | $350 |
| Student loan | $150 |
| Credit card minimums | $100 |
| Total monthly debt | $2,000 |
If gross monthly income is $5,500:
DTI = ($2,000 ÷ $5,500) × 100
DTI = 36.36%
Your estimated debt-to-income ratio is 36.4%.
How to Use the DTI Calculator
- 1
Enter your gross monthly income
Enter your income before taxes and deductions. If you know your annual income instead, divide it by 12. For example, $72,000 ÷ 12 = $6,000 gross monthly income.
- 2
Enter your housing payment
Add your monthly rent or applicable housing payment. For mortgage-related calculations, the housing amount a lender uses may follow specific underwriting rules.
- 3
Add credit card minimum payments
Enter the required monthly payments on your credit cards. Do not enter your entire credit card balance as one monthly payment.
- 4
Add auto, student, and personal loans
Include recurring monthly loan payments such as car loans, student loans, personal loans, and other installment debts.
- 5
Add other applicable monthly debts
Depending on your situation and the type of lending calculation, other recurring obligations may also be considered. Mortgage underwriting guidelines can treat different obligations differently, which is why your lender's official DTI may differ from an online estimate.
What Counts as Debt in a DTI Calculation?
Common recurring obligations can include:
- Housing
- Mortgage payments, rent, and other qualifying housing costs.
- Revolving credit
- Credit card minimum payments, not the full outstanding balance.
- Installment loans
- Auto loans, student loans, personal loans, and other installment debts.
- Other obligations
- Certain recurring support obligations and other qualifying monthly debts.
The exact obligations included can vary depending on the lender and loan program.
What Is Not Usually Included in DTI?
A debt-to-income calculation is not the same as your complete monthly budget. Ordinary living expenses generally aren't treated as debt payments in a basic DTI calculation.
- Groceries
- Everyday food spending is a living expense, not a debt payment.
- Utilities
- Electric, gas, water, phone, and internet bills are usually excluded.
- Lifestyle costs
- Entertainment, clothing, and everyday transportation costs are generally not treated as debt.
What Is a Good Debt-to-Income Ratio?
There is no single DTI percentage that guarantees loan approval. Different lenders, loan programs, and underwriting systems can use different requirements.
As general educational context, Wells Fargo currently describes its DTI ranges approximately like this:
| DTI ratio | General interpretation |
|---|---|
| 35% or less | Debt generally appears manageable relative to income |
| 36%–49% | There may be room to improve your DTI |
| 50% or more | A large portion of gross income is committed to debt |
These are guidelines, not universal approval rules.
For example, current Fannie Mae guidance says manually underwritten loans generally have a maximum total DTI of 36%, which may increase to 45% when certain credit-score and reserve requirements are satisfied. Desktop Underwriter casefiles can have a maximum allowable DTI of 50%.
Debt-to-Income Ratio for a Mortgage
DTI can be particularly important when you're preparing to apply for a mortgage.
Mortgage lenders may compare your income with:
- Proposed housing expenses
- Existing loan payments
- Credit card payments
- Student loans
- Auto loans
- Other qualifying obligations
Your DTI is only one part of mortgage underwriting. Credit profile, income documentation, assets, reserves, property details, and other factors can also matter.
Front-End DTI vs. Back-End DTI
Mortgage discussions may refer to two types of debt-to-income ratios.
Front-end DTI
Front-end DTI focuses primarily on housing expenses relative to gross monthly income.
Front-end DTI
Example: housing costs of $1,500 and gross monthly income of $6,000 give a front-end DTI of 25%.
Back-end DTI
Back-end DTI includes housing plus other qualifying recurring debts.
| Expense | Amount |
|---|---|
| Housing | $1,500 |
| Car loan | $400 |
| Student loan | $150 |
| Credit cards | $100 |
| Total | $2,150 |
With $6,000 in gross monthly income:
Back-end DTI = $2,150 ÷ $6,000 × 100 = 35.8%
How Can I Lower My Debt-to-Income Ratio?
Mathematically, your DTI decreases when your qualifying monthly debt payments decrease, your qualifying income increases, or both.
Pay down existing debts
Eliminating a monthly obligation can reduce the debt portion of your DTI calculation. Use our Loan Payoff Calculator to compare different repayment scenarios.
Avoid adding unnecessary monthly debt
Before taking out another loan, calculate how its monthly payment could change your DTI.
For example, current monthly debt of $1,500 and gross monthly income of $5,000 is a 30% DTI. Add a new $500 monthly loan payment and DTI becomes $2,000 ÷ $5,000 × 100 = 40%.
Increase qualifying income
If gross income increases while monthly debts stay the same, your DTI percentage decreases. For example, $1,500 debt ÷ $4,000 income = 37.5%, but $1,500 debt ÷ $5,000 income = 30%.
A lender may have specific rules about which income qualifies and how it must be documented.
DTI vs. Credit Utilization
Debt-to-income ratio and credit utilization are different measurements.
- Debt-to-income ratio
- Compares monthly debt payments with gross monthly income.
- Credit utilization
- Generally compares revolving credit balances with available revolving credit.
Your income is therefore central to DTI, while credit utilization is based on revolving credit balances and limits. Do not use your credit-card limit when calculating DTI.
Frequently Asked Questions
A debt-to-income ratio calculator estimates the percentage of your gross monthly income that goes toward recurring monthly debt payments.
Add your applicable monthly debt payments, divide the total by your gross monthly income, and multiply by 100. DTI = Monthly Debt Payments ÷ Gross Monthly Income × 100. The CFPB uses this same basic definition when explaining DTI.
There is no universal DTI that guarantees approval. In general, a lower DTI means less of your gross income is committed to debt. Different lenders and loan products can apply different limits.
A 30% DTI means 30% of your gross monthly income is represented by the debts included in your calculation. It falls within the 35%-or-less range Wells Fargo currently describes as generally manageable, although lenders may use different standards.
A 40% DTI means 40% of your gross monthly income is committed to the debts included in the calculation. Whether this is acceptable for borrowing depends on the loan type, lender, and other underwriting factors.
A 50% DTI means half of your gross income is represented by qualifying monthly debt payments. This can limit borrowing options, although certain mortgage underwriting systems can permit DTI ratios up to 50% in specific circumstances.
It can, depending on the purpose of the calculation. Some general consumer DTI tools include rent as a housing obligation, while mortgage underwriting follows more specific rules for current and proposed housing expenses.
Required monthly payments on revolving credit accounts such as credit cards can be included in lending-related DTI calculations.
A DTI calculation generally focuses on the applicable monthly debt obligation, rather than treating the entire outstanding credit-card balance as one month's debt payment.
Ordinary utilities are generally not treated as debt payments in basic consumer DTI calculations. Wells Fargo specifically excludes expenses such as utilities, food, and entertainment from its calculator's debt field.
DTI generally uses gross income, meaning income before taxes and other deductions.
DTI and credit scores are different measurements. DTI requires income information, while credit scoring models use information from credit reports. Debt-related information can separately influence a credit profile.
Front-end DTI focuses mainly on qualifying housing expenses relative to gross income. Back-end DTI includes housing plus other qualifying monthly debts such as auto loans, student loans, and credit-card payments.
There isn't one DTI requirement for every mortgage. Limits vary by loan program and underwriting method. For example, current Fannie Mae guidance generally limits manually underwritten loans to 36%, potentially up to 45% with specified compensating qualifications, while Desktop Underwriter casefiles can permit up to 50%.
Reducing qualifying monthly debt payments or increasing qualifying gross income can mathematically reduce your DTI. You can use the calculator to test different scenarios before applying for additional credit.
