How to use the Debt-to-Income Calculator
Enter monthly debt payments and gross monthly income. The result is debt payments as a percentage of gross income. Use the result as a borrowing estimate. Match the interest rate and term to the same loan scenario, and compare multiple terms or rates when evaluating affordability.
What this calculator does
Calculate a debt-to-income ratio from monthly debt payments and gross monthly income. It is intended to make the calculation transparent and repeatable: you provide the known values, the calculator applies the relevant relationship, and the result is shown with the units or labels used by the tool.
When this tool is useful
Use the Debt-to-Income Calculator when you need a quick, repeatable check and already have the inputs requested by the page. It is useful for comparing scenarios, checking hand calculations, planning a task, or understanding how changing one input affects the result.
How the calculation works
Debt-to-income ratio is monthly debt payments ÷ gross monthly income × 100.
Practical example
For example, compare recurring monthly debt payments with gross monthly income to calculate the ratio commonly used in lending discussions.
Things to keep in mind
- Payment estimates may exclude origination fees, taxes, insurance, penalties, changing rates, or lender-specific charges unless those inputs are explicitly shown.
- Quoted APR, payment schedules, and payoff rules can differ by lender and jurisdiction.
- Compare the estimate with the lender’s official disclosure before making a borrowing decision.
