Debt-to-Income (DTI) Calculator
Calculate your debt-to-income ratio, the number lenders check before approving a loan.
What is DTI?
Debt-to-income ratio is your monthly debt payments divided by your gross monthly income. Lenders use it to judge whether you can afford a new loan. Under 36% is generally seen as healthy, 36-43% is acceptable for many lenders, and above 43% can make borrowing harder.
How to lower it
Pay off small debts, avoid new credit before applying and increase income. Even a few points can improve the rate you are offered.
