Free Debt-to-Income (DTI) Calculator Widget
Debt-to-income is the ratio that decides most loan applications, and this widget computes both versions lenders look at: the front-end ratio covering housing alone, and the back-end ratio covering every monthly debt obligation. Visitors enter gross monthly income, a housing payment, and their car, student loan, credit card, and other debt payments.
Because most loan programs want the back-end figure at or below 43 percent, this is the calculator that tells a reader whether they are close before they apply. Mortgage content, credit counseling sites, and pre-approval explainers are where it earns its place.

Both. The front-end ratio counts the housing payment against gross monthly income; the back-end ratio adds car payments, student loans, credit card minimums, and other monthly debts. Lenders look at the back-end figure most often, and most loan programs want it at or below 43 percent.
No. This is the most sensitive calculator on the site and it works like all the others: the arithmetic runs in the visitor's browser and nothing is transmitted anywhere. No income or debt figure reaches our servers, yours, or any third party, and the widget shows no ads.
