Quick answer
Debt-to-income ratio (DTI) is the percentage of your gross monthly income that goes toward monthly debt payments. It’s calculated as:
DTI = (Total monthly debt payments) ÷ (Gross monthly income) × 100
Lenders use DTI to evaluate whether you can afford new debt. In 2026:
- DTI below 36%: Excellent. Qualifies for the best loan terms.
- DTI 36% to 43%: Acceptable for most mortgages and loans.
- DTI above 43%: Hard to qualify for a conventional mortgage. Some government-backed loans allow up to 50%.
Lowering your DTI requires paying down debt, increasing income, or both.
What counts as debt for DTI
Included in DTI:
- Rent or mortgage payment (PITI if applicable: principal, interest, taxes, insurance)
- Auto loan payments
- Credit card minimum payments
- Student loan payments
- Personal loan payments
- Alimony or child support payments
- Any other recurring required monthly debt
Not included in DTI:
- Utilities (electric, water, gas, internet)
- Insurance premiums (unless part of a mortgage)
- Groceries and food
- Subscriptions
- Gym memberships
- Entertainment
- Savings contributions
- Taxes (other than property tax in mortgage)
Example calculation
Monthly income:
- Gross salary: $6,000 ($72,000/year)
Monthly debt payments:
- Rent: $1,500
- Car loan: $400
- Student loan: $300
- Credit card minimums: $100
- Total debt payments: $2,300
DTI calculation: $2,300 ÷ $6,000 = 0.383 = 38.3%
This person has a DTI of 38.3%, which is moderate. They could qualify for most mortgages but wouldn’t get the best rates.
Front-end vs back-end DTI
Mortgage lenders use two DTI numbers:
Front-end DTI (housing ratio): Just housing-related debt divided by income. Most mortgage lenders want this under 28%.
Back-end DTI (total debt ratio): All monthly debts divided by income. Most mortgage lenders want this under 36% to 43%.
When people say “DTI,” they usually mean back-end.
DTI guidelines by loan type
| Loan type | Maximum DTI |
|---|---|
| Conventional mortgage | 43% (sometimes up to 50% with strong credit and reserves) |
| FHA mortgage | 43%, up to 50% with compensating factors |
| VA mortgage | 41% typical, but flexible |
| USDA mortgage | 41% |
| Jumbo mortgage | 43% typical |
| Personal loans | 35% to 45% typical |
| Auto loans | 45% to 50% typical |
| Credit cards | More flexible, considers both DTI and credit utilization |
These are general. Individual lenders have their own specific thresholds.
Why DTI matters
DTI is one of the top four factors lenders use to approve loans (along with credit score, income stability, and down payment).
High DTI signals:
- Less cushion for unexpected expenses
- Higher risk of missed payments
- Less ability to absorb a new monthly payment
Low DTI signals:
- Room in your budget for new debt
- Less financial stress
- Better financial discipline
Beyond loan approval, DTI affects:
- Interest rates: Lower DTI qualifies for better rates.
- Loan amounts: High DTI means smaller loan approvals.
- Insurance rates: Some insurers check DTI-related signals.
How to lower your DTI
Two levers: reduce debt or increase income.
Reduce debt
Pay down credit cards. Credit card minimums are the highest-interest debt and they shift DTI the most quickly. Eliminating a $5,000 balance with $150 minimum drops DTI by 2.5 percentage points on a $72,000 income.
Pay extra on highest-interest debt. Avalanche method: pay minimum on everything, put all extra toward the debt with the highest APR. Or use the debt payoff calculator to model both snowball and avalanche.
Consolidate debt to a lower payment. A debt consolidation loan or balance transfer card can reduce monthly minimums. Be careful: if the term stretches out, you pay more total interest even though DTI drops.
Sell assets to pay off loans. A $20,000 car loan paid off with a $20,000 savings withdrawal drops the monthly payment to $0.
Refinance for lower payment. Refinancing a mortgage to a lower rate or longer term reduces the monthly payment and DTI (at the cost of more total interest).
Increase income
Negotiate a raise. Every $5,000 raise drops DTI by roughly 2.3 percentage points at typical debt levels.
Take a second job or side hustle. Additional W-2 income counts toward DTI the same way as primary income if it has a 2-year history (for mortgages).
Count non-traditional income. Some lenders count alimony received, child support, rental income, dividend and interest income, Social Security, and VA benefits. These can lower DTI if documented.
Wait until a promotion is official. Income changes need documentation (usually 2+ paystubs) to count. Time the application accordingly.
Common mistakes
Counting gross income when lenders count different amounts. Self-employed income is averaged over 2 years. Overtime and bonus income need a 2-year history. Commission income is averaged.
Forgetting credit card minimum. Lenders count the minimum payment on all open cards, not zero if you pay the card off monthly.
Paying off a small balance right before applying. Shows on credit reports for 30 to 60 days after. If timing matters, pay 2+ months before applying.
Opening a new card to consolidate right before applying. New credit inquiries ding your score temporarily and can push DTI up (new minimum payment).
DTI vs credit utilization ratio
These are different metrics, both important.
- DTI: Monthly debt payments ÷ monthly income. Used by lenders for approvals.
- Credit utilization ratio: Current balances ÷ total credit limits. Used by credit bureaus for scoring.
Example: $2,000 balance on a $10,000 limit = 20% credit utilization. You could have a low DTI and high utilization, or vice versa.
Both should be low. Target utilization under 30%, ideally under 10%.
DTI thresholds at a glance
| DTI range | Interpretation | Loan access |
|---|---|---|
| Below 20% | Excellent | Best rates available, easy approval |
| 20% to 35% | Healthy | Good rates, most loan types available |
| 36% to 43% | Moderate | Approval likely, higher rates |
| 44% to 50% | Stretched | FHA/VA possible, conventional difficult |
| Above 50% | High risk | Most lenders decline; manageability concerns |
FAQ
How do I calculate my DTI?
Add up all required monthly debt payments (rent/mortgage, car, student loans, credit card minimums, personal loans). Divide by your gross monthly income (before taxes). Multiply by 100.
Does DTI use gross or net income?
Gross. Pre-tax, pre-deduction income.
Do savings contributions count toward DTI?
No. Only required debt payments count.
What DTI do I need for a mortgage?
Most conventional mortgages want DTI under 43%. FHA allows up to 50% with strong compensating factors. The lower your DTI, the better your rate.
Can I include rental income in DTI?
If you own rental property, most lenders use 75% of gross rental income (to account for vacancy and repairs). Needs 2-year history for full credit.
Does DTI affect credit score?
Not directly. Credit scores use credit utilization, not DTI. But high DTI often correlates with high utilization, which does affect score.
How do I improve DTI quickly?
Three fastest moves: (1) pay down credit cards, (2) pay off small installment loans entirely, (3) document additional income sources. Doing all three can drop DTI 5-10 points in 2-3 months.
Should I apply for a mortgage if my DTI is 45%?
Maybe. FHA and VA loans often accept higher DTI, but you’ll pay more in interest and likely PMI. Consider waiting 6 to 12 months to pay down debt for a better rate.
Is a 50% DTI bad?
It’s high. You’d be spending half your gross income on debt, which leaves little for taxes, savings, and discretionary spending. Most lenders won’t approve new debt at this level. It’s also a lifestyle stress indicator.
Bottom line
DTI is the number lenders use to decide if you can handle more debt. Keep it under 36% for optimal loan terms and financial breathing room.
Lower DTI by paying down credit cards and loans, increasing income, or both. If you’re about to apply for a major loan (mortgage, auto), aim to optimize DTI 3 to 6 months before applying.
