How this calculator works

Debt-to-income ratio (DTI) compares your monthly debt payments with your gross monthly income. Lenders use it to judge whether you can absorb another payment.

DTI = (housing payment + other monthly debt payments) ÷ gross monthly income × 100.

Gross income is pay before taxes and deductions. If income is 0 the ratio has no meaning, so the tool returns nothing rather than a bogus figure.

Thresholds differ by lender and program, so ask the lender what it wants instead of assuming a single cutoff.

Frequently asked questions

Which payments count as debt?
Recurring obligations: rent or mortgage, auto loans, student loans, personal loans, and minimum card payments.
Gross or net income?
Gross income, before taxes and deductions. Lenders compare debt with gross pay.
What ratio do lenders want?
It varies by lender and program, and credit and savings matter too. Ask the lender for its own threshold.
Does a low ratio guarantee approval?
No. Lenders also weigh credit history, income stability, and the size of the loan. The ratio is one factor among several.
