Debt-to-Income Ratio Calculator
Use our free Debt-to-Income (DTI) Ratio Calculator to determine how much of your monthly income goes toward debt payments. Lenders commonly use the debt-to-income ratio when evaluating mortgage applications, personal loans, auto loans, and other forms of credit. A lower DTI ratio generally indicates stronger financial health and may improve your chances of loan approval.
What Is a Debt-to-Income Ratio?
A Debt-to-Income (DTI) ratio is a financial metric that compares your total monthly debt obligations to your gross monthly income. It helps lenders assess whether you can comfortably manage additional debt.
The DTI ratio is expressed as a percentage and is calculated using the following formula:
DTI Ratio = (Total Monthly Debt Payments ÷ Gross Monthly Income) × 100
For example, if your monthly debt payments total $1,500 and your gross monthly income is $5,000, your DTI ratio would be:
(1,500 ÷ 5,000) × 100 = 30%
A 30% DTI ratio means that 30% of your monthly income is used to pay existing debts.

What Counts as Monthly Debt?
Common debt obligations include:
- Mortgage payments
- Rent payments (if included for budgeting purposes)
- Auto loans
- Student loans
- Credit card minimum payments
- Personal loans
- Home equity loans
- Child support obligations
- Alimony payments
Generally, everyday living expenses such as groceries, utilities, insurance premiums, transportation costs, and entertainment expenses are not included in DTI calculations used by lenders.
Understanding Your DTI Ratio
Below 20% — Excellent
A DTI ratio below 20% indicates a very strong financial position. You have substantial income available after covering debt obligations and may qualify for favorable loan terms.
20% to 35% — Good
Most lenders view this range positively. Borrowers in this category often have manageable debt levels and a strong likelihood of loan approval.
36% to 43% — Moderate
A DTI ratio in this range may still qualify for many loans, but lenders could perform additional reviews of your finances and repayment capacity.
Above 43% — High
A DTI ratio above 43% can make loan approval more difficult. Many mortgage programs use 43% as an important qualification threshold, although requirements vary by lender.
Why Lenders Care About Debt-to-Income Ratio
Lenders use DTI ratios because they help predict whether a borrower can handle additional debt responsibly. Even applicants with excellent credit scores may face challenges obtaining financing if their debt obligations consume a large portion of their income.
A lower DTI ratio can potentially help you:
- Qualify for mortgages
- Obtain personal loans
- Secure auto financing
- Receive better interest rates
- Improve borrowing flexibility
Tips to Improve Your Debt-to-Income Ratio
If your DTI ratio is higher than desired, consider these strategies:
Pay Down Existing Debt
Reducing credit card balances and loan obligations can lower monthly debt payments and improve your ratio.
Increase Your Income
Additional income from salary increases, side businesses, freelance work, or other sources can reduce your DTI percentage.
Refinance High-Payment Loans
Refinancing may reduce monthly payments and improve affordability.
Avoid Taking on New Debt
Limiting new credit obligations can prevent your DTI ratio from increasing further.
Frequently Asked Questions
What is a good debt-to-income ratio?
Generally, a DTI ratio below 36% is considered good, while ratios below 20% are considered excellent.
Does a higher income automatically improve DTI?
Not necessarily. DTI depends on both income and debt payments. High income can help, but excessive debt can still result in a high DTI ratio.
Is DTI the same as a credit score?
No. A credit score measures creditworthiness based on borrowing history, while a DTI ratio measures the relationship between debt payments and income.
Can I qualify for a mortgage with a high DTI ratio?
Possibly. Some lenders and loan programs allow higher DTI ratios, but qualification requirements vary.
