Debt to Income Calculator
Calculate your debt-to-income ratio to see if you qualify for a mortgage or loan. Compare front-end and back-end DTI.
How to Use the Debt to Income Calculator
- Enter your monthly gross income before taxes and deductions. Include all sources: salary, bonuses, commissions, alimony, child support, and investment income.
- Enter your monthly housing costs: rent or mortgage payment, property taxes, homeowners insurance, and HOA fees. This calculates your front-end DTI.
- Enter your total monthly debt payments: credit cards, car loans, student loans, personal loans, and any other recurring debt obligations. This calculates your back-end DTI.
- Click Calculate DTI to see your ratios, what they mean for loan qualification, and recommendations.
- Compare your results to lender guidelines: front-end under 28% and back-end under 36% for conventional loans, or up to 43% for FHA loans.
Formula & Method
Front-End DTI (Housing Ratio):Front-End DTI = (Monthly Housing Costs / Monthly Gross Income) x 100
Back-End DTI (Total Debt Ratio):Back-End DTI = (Total Monthly Debt Payments / Monthly Gross Income) x 100
What Counts as Debt:
- Credit card minimum payments
- Car loans and leases
- Student loans (use actual payment or 0.5-1% of balance if deferred)
- Personal loans
- Child support and alimony payments
- Other recurring monthly obligations
Lender Guidelines:
- Conventional Loans: Front-end < 28%, Back-end < 36%
- FHA Loans: Front-end < 31%, Back-end < 43%
- VA Loans: Back-end < 41% (no front-end requirement)
- USDA Loans: Back-end < 41%
- Jumbo Loans: Back-end < 43% (often stricter)
Note: Some lenders may allow higher ratios with compensating factors like high credit scores, large cash reserves, or low loan-to-value ratios.

Frequently Asked Questions
What is a good debt-to-income ratio?
A back-end DTI under 36% is considered good by most lenders. Under 20% is excellent and indicates strong financial health. Between 37-42% is manageable but may limit loan options. Above 43% makes mortgage qualification very difficult with most lenders.
What is the difference between front-end and back-end DTI?
Front-end DTI only includes housing costs (mortgage/rent, taxes, insurance, HOA). Back-end DTI includes ALL monthly debt payments plus housing. Lenders look at both: front-end shows if you can afford the home, back-end shows your overall debt burden.
Does DTI include utilities or groceries?
No, DTI only includes recurring debt obligations and housing costs. Utilities, groceries, insurance (non-home), entertainment, and other living expenses are not counted. However, lenders may consider these in a broader affordability analysis.
How can I improve my DTI ratio?
1) Pay down existing debt to reduce monthly payments, 2) Increase your income through raises, side jobs, or bonuses, 3) Avoid taking on new debt before applying for a mortgage, 4) Refinance existing loans to lower monthly payments, 5) Consider a longer loan term to reduce monthly payments (though this increases total interest).
Do lenders use gross or net income for DTI?
Lenders always use gross income (before taxes and deductions) for DTI calculations. This is standard across all loan types. Your net (take-home) pay will be lower, so make sure you can comfortably afford payments from your actual disposable income.
People Also Ask
What is the maximum DTI for a mortgage?
For conventional loans, the maximum back-end DTI is typically 43%, though some lenders allow up to 50% with strong compensating factors. FHA loans allow up to 43% back-end DTI (50% in some cases). VA loans use a guideline of 41% but can go higher with residual income analysis.
Does rent count in DTI?
Yes, your current rent or proposed mortgage payment counts as a housing expense in your front-end DTI. If you are buying a home, lenders use the proposed mortgage payment (including taxes and insurance) to calculate your front-end ratio.
Is 50% DTI too high for a mortgage?
Yes, 50% DTI is generally considered too high for most conventional mortgages. At this level, half your gross income goes to debt payments, leaving little room for living expenses, savings, and emergencies. Some FHA and non-QM lenders may accept 50% with strong compensating factors, but expect higher interest rates.
How do student loans affect DTI?
Student loans are included in DTI using your actual monthly payment. If your loans are in deferment or forbearance, lenders typically use 0.5% to 1% of the outstanding balance as the monthly payment for qualification purposes. Income-driven repayment plans may use the actual reduced payment amount.
Can I get a mortgage with high DTI?
It depends on the loan type and lender. Conventional loans typically require DTI under 43%. FHA loans may allow up to 50% with automated underwriting approval. VA loans focus on residual income rather than strict DTI limits. Non-QM (non-qualified mortgage) lenders may accept higher DTIs but charge significantly higher interest rates and fees.
