What is Debt-to-Income Ratio Calculator?
Understanding Debt-to-Income Ratios
Debt-to-income (DTI) ratio is a key metric lenders use to evaluate your ability to manage monthly payments and repay borrowed money. It compares your total monthly debt payments to your gross monthly income, expressed as a percentage.
Types of DTI Ratios
Front-End Ratio
Compares housing costs (PITI + HOA) to gross monthly income. Most lenders prefer this ratio to be 28% or lower.
Housing Costs ÷ Gross Income × 100
Back-End Ratio
Compares all monthly debt payments to gross monthly income. Conventional loans typically require 36% or lower.
Total Monthly Debts ÷ Gross Income × 100
DTI Requirements by Loan Type
| Loan Type | Front-End Max | Back-End Max | Notes |
|---|---|---|---|
| Conventional | 28% | 36% | Standard for most lenders |
| FHA | 31% | 43% | More flexible for first-time buyers |
| VA | No limit | 41% | Uses residual income method |
| USDA | 29% | 41% | Rural and suburban properties |

FAQ - Debt-to-Income Ratio Calculator
Ideally, your DTI should be below 36% for all debts and below 28% for housing costs. However, some loan programs allow higher ratios - FHA loans permit up to 43% back-end DTI with compensating factors.
