How this calculator works

Debt-to-income ratio compares your monthly debt payments with your gross monthly income, which is income before taxes and deductions. Lenders use it to judge whether you can take on another payment, so it matters when you apply for an installment loan or any other credit.

The housing ratio is your housing payment divided by income, and the total DTI adds all other monthly debt payments on top. The calculator places the result in a band: below 36% is comfortable for most lenders, 36 to 43% is acceptable to many, 43 to 50% is tight, and above 50% is where most lenders decline. If income is zero the ratio is undefined and the calculator returns no value.

Use gross income and include recurring obligations such as rent or mortgage, auto loans, student loans, personal loans, and minimum credit card payments. Thresholds vary by lender, so confirm the cutoff with the lender you are applying to.

Frequently asked questions

Should I use gross or net income?
Use gross income, which is your pay before taxes and other deductions. Lenders compare debt payments against gross income, so using net income would understate your true ratio.
What counts as monthly debt?
Include recurring obligations such as rent or mortgage, auto loans, student loans, personal loans, and minimum credit card payments. Everyday spending like groceries and utilities is not counted as debt here.
What DTI do lenders look for?
Many lenders look for a total DTI at or below 43%, though some allow more and some want less. Thresholds vary by lender and loan program, so ask the lender what it requires.
Does a low DTI guarantee approval?
No. Lenders also review credit history, income stability, and the size of the loan, so DTI is one factor among several. A strong ratio helps but does not guarantee a decision.
