Debt-to-Income Ratio (DTI) is a financial measurement that compares a person’s monthly debt payments to their gross monthly income. Financing providers often use DTI to evaluate an applicant’s ability to manage additional financial obligations.
DTI is typically expressed as a percentage.
How Debt-to-Income Ratio Works
To calculate DTI, total monthly debt payments are divided by gross monthly income.
For example:
- Gross monthly income: $6,000
- Monthly debt payments: $2,000
DTI = $2,000 ÷ $6,000 = 33.3%
A lower DTI generally indicates that a smaller portion of income is committed to existing debt obligations.
Debt-to-Income Ratio and Islamic Financing
Debt-to-Income Ratio is commonly used in both conventional and Islamic financing. Although Islamic financing follows different contractual structures, financing providers may still evaluate an applicant’s income and existing obligations to determine affordability and qualification.
DTI is often considered alongside credit history, employment, assets, and other underwriting factors.
What is Included in DTI?
Monthly obligations commonly included in DTI calculations may include:
- Housing payments
- Auto financing payments
- Student loans
- Credit card minimum payments
- Personal loans
- Other recurring debt obligations
