How it works
Add up the required monthly payments on debts, such as car loans, credit cards, student loans and any housing payment. Divide that total by gross monthly income, which is income before tax, and multiply by 100 to get a percent.
This page shows the math only. Lenders set their own limits, and they look at more than this one number.
Worked example
Monthly debt payments of $1,500.00 on $5,500.00 of gross monthly income make a debt-to-income ratio of 27.3%.
Questions
Gross or take-home income?
Lenders usually use gross income, which is before tax and deductions. Use that figure here so the result matches how it is usually measured.
Which debts count?
Required monthly payments usually count. Groceries, utilities and similar everyday bills usually do not.
What number do lenders want?
Limits vary by lender and loan type. Ask a lender or a housing counselor what they look for.
