Debt-to-income ratio (DTI) equals required monthly debt payments divided by gross monthly income, multiplied by 100. If required debts total $2,000 per month and gross income is $6,000 per month, DTI is 33.33%. The ratio is a screening measure, not an approval promise, because each lender and loan program applies its own rules.
how to calculate debt to income ratio: the measured relationship
Debt-to-income ratio is the percentage of gross monthly income represented by required monthly debt payments. DTI measures payment obligations against income. Credit utilization instead compares card balances with card limits, so a borrower can have a modest DTI and a high utilization ratio at the same time.
| Monthly debt payments | $2,000 |
|---|---|
| Gross monthly income | $6,000 |
| DTI | 33.33% |
| Formula unit | monthly dollars ÷ monthly dollars |
how to calculate debt to income ratio: a worked dollar case
List a $1,500 housing payment, $100 auto-loan payment, and $400 of other required monthly debt. The total is $2,000. Divide $2,000 by $6,000 of income before tax withholding: 0.3333, or 33.33%. Adding a proposed $500 housing payment would make the modeled total $2,500 and the modeled DTI 41.67%, provided every input uses the same monthly period.
how to calculate debt to income ratio: calculation method
DTI = total required monthly debt payments ÷ gross monthly income × 100. Gross income means income before taxes and other deductions for this calculation; net pay is a different denominator and produces a different percentage.

Common mistakes in How to calculate your debt-to-income ratio (DTI)
Do not put an entire $20,000 auto balance in the numerator; the formula uses its required monthly payment. Do not divide by take-home pay if the question is a lender-style gross DTI. Leaving out a required student-loan, support, or housing payment can make a precise-looking percentage misleading.
Where this calculation stops
The ratio cannot decide which income a lender will count, whether overtime continues, what debt is reportable, or what limit applies to an individual product. It also says nothing by itself about emergency savings, property condition, interest-rate risk, or the actual cash left after bills.
how to calculate debt to income ratio: source check
The Consumer Financial Protection Bureau gives the same definition and a $2,000 monthly-debt, $6,000 gross-income example, while noting that limits vary by lender and product. Read the named source. The incomeledger record should be reconciled to the disclosure, statement, tax bill, or agreement that governs that exact transaction.
how to calculate debt to income ratio: using the output
The incomeledger output keeps each input's named unit and date adjacent to the result. Update the incomeledger scenario when its rate, balance, payment, or property value changes.
