What This Calculator Helps You Understand
Calculate the percentage of gross monthly income committed to recurring monthly debt payments and separate housing-only debt from total debt.
When This Calculator Is Most Useful
Use it before applying for a mortgage, auto loan, personal loan, or other credit, or when you want to understand how strongly fixed debt payments are competing with income.
How to Use This Calculator
- Enter current, realistic information in each field.
- Keep income, expenses, rates, and time periods consistent.
- Calculate the result, then test at least one conservative scenario.
- Review the explanation and limitations before making a decision.
How the Calculation Works
The calculator divides monthly housing obligations by gross monthly income for front-end DTI and divides all entered recurring monthly debt obligations by gross monthly income for back-end DTI.
How to Interpret Your Results
A lower DTI generally means less gross income is already committed to debt. Lenders use different rules, loan programs, credit standards, and qualifying-income calculations, so no single DTI percentage guarantees approval or denial.
Helpful Planning Tips
Common Mistakes to Avoid
