Your debt-to-income (DTI) ratio compares the total of your monthly debt payments to your gross monthly income. Lenders use it to gauge how comfortably you can take on (and repay) new credit. You’ll calculate it by adding your monthly debt obligations, dividing the sum by your gross monthly income, and multiplying by 100 to get a percentage.
Quick Facts
- Definition: DTI shows how much of your gross monthly income goes to debt payments each month.
- Use: Lenders assess DTI to evaluate capacity, approve applications, set loan amounts, and price risk.
- Calculation: (Monthly debt total ÷ gross monthly income) × 100 = DTI percentage.
Mini FAQ
Is DTI the same as a credit score?
No. Credit scores reflect payment history and credit behavior; DTI measures monthly capacity. Lenders generally consider both—and your documentation—before making a decision.
Is a lower DTI always better?
Yes. A lower ratio usually signals more room in your budget, which can unlock higher approvals and better terms (all else equal).
Does DTI use net or gross income?
Gross income. Unless otherwise specified, you’ll use income before taxes and deductions for standard DTI calculations.
Key Takeaways
- DTI formula: Add monthly debt payments, divide by gross monthly income, then multiply by 100 to get your percentage.
- What counts: Mortgage or rent, car loans, student loans, personal loans, and credit card minimums—plus other recurring debt obligations.
- What doesn’t: Utilities, groceries, insurance premiums, and variable living costs typically aren’t part of the DTI calculation.
- Why it matters: Lenders use DTI to size approvals, evaluate capacity, and set terms alongside your credit and documentation.
- Benchmarks: Lower is better; many mortgage scenarios target total DTI below common thresholds for stronger approvals.
- Lowering DTI: Pay down revolving balances, increase income documentation, and avoid new debt before you apply.

What is a debt to income (DTI) ratio?
DTI shows the share of your gross income consumed by debt payments. You add your monthly debt obligations, divide by gross monthly income, then multiply by 100 to get a percentage lenders use to size approvals for a VA home loan. For a deeper grounding on consumer capacity concepts, see the CFPB’s overview of DTI (linked inline below to a *.gov page). Pair DTI with a realistic budget so the payment fits your household, not only a guideline.
- A single capacity number: DTI converts a complex budget into one percentage, helping lenders compare obligations to income and gauge how comfortably you can absorb a new payment without crowding out essentials.
- Used across loans: Mortgage underwriters rely on DTI, but auto and personal lenders do as well. A lower DTI can improve approvals, eligible loan amounts, and pricing across different products and institutions.
- Different from credit score: Your score measures past behavior and utilization, while DTI measures current capacity. Lenders use both to form a full picture of risk and repayment ability.
- Total your monthly debts. Include mortgage or rent, installment loans, and credit card minimums. Exclude utilities, groceries, and insurance premiums unless a program specifically requires them.
- Find gross monthly income. Use income before taxes and deductions, including base pay and stable supplemental income that guidelines accept as reliable.
- Compute your ratio. Divide debts by gross income, then multiply by 100. A lower percentage indicates more capacity for new obligations.
Because it captures both obligations and income, DTI is a reliable and comparable indicator of affordability for lenders and borrowers. Use it early to set a realistic price range and to plan improvements before you apply.
What debts are included in a DTI calculation?
DTI includes recurring, scheduled debt payments due each month. Think mortgage or rent, auto and student loans, personal loans, and the minimum due on credit cards. The CFPB’s step by step guide to calculating DTI explains which payments belong in the numerator and which do not (CFPB calculation guide).
- Installment loans: Car, student, personal, and consolidation payments count because you are obligated to pay fixed amounts on a schedule until balances are fully repaid under the note.
- Revolving debt minimums: Only the minimum due on credit cards counts, not the full balance. Underwriters focus on monthly cash outflow, not the available credit line.
- Housing costs: For homeowners, include principal, interest, taxes, and insurance and any HOA dues. For renters, the lease payment is used as the housing component of DTI.
- Gather statements. Pull the latest statements for each loan and card. Use the current minimum for revolving accounts and the scheduled payment for installment loans.
- Confirm housing figure. For mortgages, total full PITI and any HOA dues. For rent, use the lease amount, not utilities or other variable costs.
- List special items. Add other recurring obligations such as alimony or child support when underwriting requires them to be included.
Listing every recurring debt accurately is essential. Missing payments can understate your DTI and lead to approval changes late in the process.
What income counts toward DTI and what does not?
Use gross, stable, documentable monthly income. Employers’ base pay and reliable supplemental income that meets continuity standards can count. Irregular or unverifiable income usually does not. Ability to repay concepts are discussed in federal rule materials that inform lenders’ capacity assessments (CFPB DTI thresholds).
- Included income: W-2 wages, salaries, retirement or pension income, and verifiable benefits that meet continuity tests typically qualify as gross income when well documented.
- Potentially includable: Overtime, commissions, bonuses, or self-employment income can count when you document a stable history and reasonable expectation to continue under program rules.
- Excluded items: Cash gifts without proper documentation, sporadic gig income without a history, or noncash fringe benefits generally do not count toward qualifying income.
- Document sources. Gather recent pay stubs, W-2s or 1099s, award letters, and tax returns. Underwriters need proof and continuity to include income.
- Average variable pay. If you earn commissions or overtime, lenders usually average a longer history rather than accept a single high month.
- Be conservative. Exclude windfalls or uncertain side earnings. Overestimating income inflates affordability and can produce approval setbacks.
Clear and well documented income prevents re-verifications and last minute changes to your approval amount and helps automated systems produce stable findings.
What expenses are not included in DTI?
Utilities and everyday living costs are not part of the formula. DTI focuses on contractual debt payments, not variable expenses such as groceries, gas, premiums, or subscriptions. Those still matter for budgeting but are outside the ratio.
- Variable living costs: Day to day expenses fluctuate and are not contractual debt. While they do not affect DTI directly, plan for them to avoid being house rich and cash poor.
- Insurance premiums: Health, auto, and life premiums are typically excluded from DTI even though they are essential. Track them in a separate household budget.
- Credit limits: Only minimum payments on revolving accounts are counted. Available credit and limits do not enter DTI math directly.
- Separate budgets. Track variable expenses outside your DTI worksheet so you see the complete picture of monthly cash flow.
- Recheck subscriptions. Identify recurring services and decide whether they are essential during mortgage or credit applications.
- Stress test. Add a buffer for utilities and insurance increases. A comfortable DTI can hide a tight real world budget.
DTI is not a full budget. Complement it with a realistic spending plan to protect cash flow.
How do you calculate your DTI step by step?
Add debts, divide by gross income, then multiply by 100. With a simple worksheet and monthly statements, you can compute your DTI in minutes and see how changes in debt or income will move your ratio (CFPB calculation guide).
- Example debts: Suppose you pay 1,500 dollars for rent, 300 dollars for a car loan, and 200 dollars for student loans. Your monthly debt is 2,000 dollars. With 5,000 dollars in gross income, DTI is 40 percent.
- Front end and back end: Some contexts use a housing ratio and a total DTI. Mortgages evaluate both, with total DTI the stricter constraint.
- What it means: A 40 percent DTI indicates forty cents of every gross income dollar goes to debt. Lowering that number increases capacity and can improve loan terms.
- List debts. Write down each monthly debt payment, including minimum card payments and housing. Total the list carefully to avoid undercounting.
- Confirm income. Use current gross monthly income from pay documents. For variable income, use an average your lender will accept.
- Do the math. Divide debts by income and multiply by 100. Recalculate after paying balances or adjusting targets to measure improvement.
Once you know the number, you can plan steps to lower DTI before applying, which can improve approval odds and pricing.
What is a good DTI for loan approvals?
Lower is better, and thresholds vary by loan type. Many mortgage scenarios prefer total DTI at or below common benchmarks. Some programs allow higher ratios when strong compensating factors exist (CFPB DTI thresholds).
- Conventional guidelines: Caps vary with credit, down payment, and automated findings. Strong files can qualify at higher ratios when risk factors are favorable and reserves are ample.
- Government programs: Program rules differ. Some accept higher DTI if other safeguards exist such as robust reserves or verified payment shock tolerance.
- Residual income for VA: VA underwriting weighs residual income alongside DTI to ensure sustainable budgets for borrowers and families by region and household size.
- Check program rules. Ask your lender for the program’s DTI tolerance and which compensating factors can offset a higher ratio.
- Model a buffer. Keep DTI under the cap by several percentage points to absorb changes in taxes or insurance.
- Document strengths. Show reserves, job tenure, and clean payment history. These can support approvals when DTI is near the boundary.
DTI targets are guideposts rather than guarantees. Complete and well documented files often matter as much as the number itself.
What is the difference between front end and back end DTI?
The front end ratio measures housing and the back end ratio measures total debt. Lenders examine both, but the back end ratio usually governs because it captures every monthly obligation.
| Ratio | Includes | Excludes | Common Use |
|---|---|---|---|
| Front End DTI | Mortgage PITI and HOA dues or rent | All non housing debts | Evaluates housing affordability specifically |
| Back End DTI | Housing plus all monthly debt payments | Variable living expenses | Evaluates total capacity for new credit |
- Compute both: Calculate the housing only ratio and the total ratio to see whether stress is driven by shelter costs or by other debts.
- Target improvements: If the back end ratio is high, focus on paying down revolving and installment balances instead of only trimming housing expenses.
- Recheck monthly: As balances drop or income rises, recompute both ratios. Visible progress keeps your plan on track.
How does DTI compare with VA residual income requirements?
DTI measures a percentage while residual income measures dollars left after debts. VA emphasizes residual income by region and family size. The rule text appears in the eCFR for VA loans (eCFR §36.4340).
- Complementary tools: A borrower can have a higher DTI and still qualify when residual income comfortably exceeds the minimum, showing day to day expenses remain manageable.
- Family and region: Residual tables vary by household size and geography, reflecting cost differences that a single percentage cannot capture well on its own.
- Practical takeaway: Improving DTI helps, but raising residual income by trimming fixed debts or increasing documented earnings can be even more persuasive in VA underwriting.
- Check the table. Ask which residual income threshold applies to your household size and region so you know your target.
- Raise the buffer. Reduce recurring debts or increase stable income to exceed the threshold by a healthy margin.
- Document clearly. Provide pay documentation and proof of debt reductions so underwriters can validate residual calculations quickly.
How can you lower your DTI quickly and sustainably?
Pay down revolving balances and avoid new debt before applying. Small changes to card utilization can reduce minimums and improve automated findings. Document income thoroughly to support the highest eligible qualifying average.
- Target revolving debt: Lowering credit card balances reduces minimum payments that feed DTI and can also lift credit tiers for better pricing and eligibility.
- Avoid new obligations: New installment loans add fixed payments that push DTI higher. If you must borrow, keep amounts small and terms short to limit impact.
- Document income thoroughly: Provide clear pay stubs, W-2s or 1099s, and benefit letters. For variable pay, longer histories support higher qualifying averages.
- Make strategic payments. Pay revolving accounts before statement close so lower balances and lower minimums appear on the reports lenders view.
- Consolidate carefully. When consolidation lowers total required payments, confirm there are no penalties or fees that erase the benefit.
- Time your application. Apply when balances are low and documents are current to give underwriters a clean snapshot of improved capacity.
DTI examples and quick benchmarks
This simple table shows how small changes in debt can move the ratio. Use it to plan a fast improvement before you lock a rate or submit a full file.
| Gross Monthly Income | Total Monthly Debt | Calculated DTI | Simple Action Plan |
|---|---|---|---|
| $5,000 | $2,000 | 40% | Pay $1,000 toward cards before the next statement to drop minimums and recheck DTI. |
| $5,000 | $1,800 | 36% | Hold off on new auto financing, keep card balances low, and update documents. |
| $6,000 | $2,000 | 33% | Maintain low revolving utilization and keep reserves for stronger pricing. |
Common mistakes and myths to avoid
Do not treat DTI as your budget or as the only approval factor. DTI omits living costs and approvals weigh several metrics. Avoid errors that inflate risk and create surprises.
- Ignoring non DTI costs: Utilities, childcare, and insurance premiums do not appear in DTI, but they matter to your wallet. Build them into a separate household budget.
- Overstating income: Counting irregular or undocumented income can backfire. If it is not stable and provable, it probably will not count for qualification.
- Hugging the cap: Meeting a program limit does not guarantee comfort. Leave buffer room for escrow changes, maintenance, and life events.

The Bottom Line
Your DTI is a quick snapshot of monthly capacity and lower is better. Add recurring debts, divide by gross income, and convert to a percentage. Improve it by trimming revolving balances, avoiding new obligations, and tightening documentation. Remember that DTI is not your whole budget, so plan for living costs outside the ratio. For VA loans, residual income adds another safety check. Approvals and terms reward borrowers who combine a strong DTI with clean documentation, realistic reserves, and a plan that still works if expenses rise or incomes change modestly.
