Question 1

What is a good debt-to-income ratio?

Accepted Answer

Most conventional mortgage lenders want a DTI below 36%, with housing costs below 28% of gross income. FHA loans allow DTI up to 43%, and some lenders approve up to 50% with compensating factors like high credit scores or large down payments. Below 28% is considered excellent for any loan type.

Question 2

Does DTI use gross or net income?

Accepted Answer

Lenders universally use gross (pre-tax) monthly income for DTI calculations. This is your income before federal taxes, state taxes, Social Security, and Medicare are withheld. Using gross income means the DTI percentage will appear lower than it would if calculated on take-home pay.

Question 3

How do I lower my debt-to-income ratio quickly?

Accepted Answer

There are two levers: reduce monthly debt payments or increase gross income. Paying off small debts entirely removes their minimum payments from your DTI. Avoiding new credit applications, refinancing at lower rates, and increasing income through a raise or side work all improve the ratio. Even paying down one credit card to zero can noticeably shift the number.

Question 4

Does my DTI affect my credit score?

Accepted Answer

DTI does not directly factor into credit scores — FICO and VantageScore do not use income data. However, the debts that drive up your DTI (credit card balances, loan balances) do affect credit utilization and payment history, which are the two largest components of your credit score.

Question 5

Is DTI calculated the same way for all loan types?

Accepted Answer

The calculation is the same, but the acceptable threshold varies. Conventional mortgages target below 36–43%. FHA mortgages allow up to 43–50%. VA loans technically have no maximum DTI but use it as a factor. Auto lenders typically want below 45–50%, while personal loan lenders vary widely from 35% to 50%.
