Smart Tips

DTI uses monthly numbers—convert annual income and yearly bills to monthly for consistency.
Lowering revolving debt minimums (or paying down card balances) can improve DTI and also help credit utilization.
For mortgages, include taxes and insurance in the housing payment for a more realistic housing ratio.
If you're between jobs or income is irregular, use a conservative average income to avoid overestimating affordability.
DTI is only one factor—credit score, down payment, and loan type can change what's acceptable.

Understanding DTI Calculation

What is Debt-to-Income (DTI)

Debt-to-Income (DTI) is a percentage that compares your recurring monthly debt payments to your monthly income. Lenders use it to assess how much of your income is already committed before approving a new loan.

How is DTI Calculated

This tool calculates two key ratios: back-end DTI (all monthly debts divided by income) and front-end ratio (housing payment divided by income). Back-end DTI is the primary affordability metric across many loan types, while front-end focuses on housing costs.

Core Formulas

Back-end DTI (%) = (Housing Payment + Other Debt Payments) ÷ Monthly Income × 100
Front-end Ratio (%) = Housing Payment ÷ Monthly Income × 100

Frequently Asked Questions

What debts should I include in DTI
Include recurring monthly obligations that show up as required payments: rent/mortgage, auto loans, student loans, minimum credit card payments, personal loans, and any court-ordered payments. Day-to-day spending (groceries, utilities) is usually not counted in lender DTI, but it matters for your real budget.
Should I use gross or net income
Many lenders evaluate DTI using gross income. Net income can be more practical for personal affordability because it reflects take-home pay after taxes and deductions. This tool supports both so you can compare.
Does a lower DTI guarantee approval
No. Approval also depends on credit history, employment stability, collateral, loan type, down payment, and lender policy. DTI is an important constraint, but not the only one.
Why does this tool not convert currency amounts
Currency selection changes symbols and formatting only. Because DTI is a ratio, conversion is not necessary for correctness as long as income and debts are in the same currency.
What is considered a "good" DTI
Acceptable DTI varies by lender and product. As a planning rule of thumb, lower is generally better because it leaves more buffer for savings and unexpected expenses. Use the "DTI Status" badge to get a quick signal and review your remaining income for realism.
