Why Backend DTI is Important

Historically lenders have typically preferred new home buyers to have a back-end DTI ratio somewhere below the 40% to 42% range. If overall debt payments consume too much of your paycheck then you do not have much flexibility to deal with unforeseen circumstances. Those who have a significant buffer & plenty of disposible income are seen as good credit risks to lend money to. Those who are seen as a poor credit risk may not be extended credit, or they may be offered funding at a significantly higher rate of interest.

Rising Debt Limits

Due to rising student loan debt, in 2017 the backend DTI limit has been lifted to 50% by Freddie Mac, Fannie Mae & the FHA. People who are close to the limit may need to show other positive attributtes (like a large downpayment, a high FICO credit score and/or a stable employment history) to qualify for funding.

Front End vs Back End DTI

This calculator shows your frontend & backend debt to income ratios. Historically lenders have preferred the front end ratio to be below 28%. The calculation for the front end ratio is quite similar to the calculation for the back end ratio. The main difference is the front end ratio looks only at your mortgage & housing related payments for calculating the debt load, while the backend ratio also includes all other monthly debt obligations along with the housing expenses.
