Debt-to-Income Ratio Calculator
Estimate the percentage of gross monthly income used for housing and recurring debt payments.
Quick answer
Use gross income before taxes. Include recurring required debt payments, not the full outstanding balances. Results show housing-only and total DTI percentages.
Formula used
Housing ratio = monthly housing payment ÷ gross monthly income. Total DTI = (housing payment + other recurring monthly debt payments) ÷ gross monthly income.
Worked example
With $6,000 gross monthly income, $1,800 housing, and $600 other debt payments, total monthly debt is $2,400 and total DTI is 40%.
How to interpret the result
Use the comparison to test scenarios, then verify important decisions against current account documents and provider rules. A calculator is most useful when the inputs match the balance, rate, payment timing, and fees that apply to you.
Limitations
Lenders define income and debts differently and use their own underwriting standards. This educational result does not determine approval, affordability, or a safe borrowing level.
