What is a debt-to-income ratio?

Your DTI ratio is the percentage of your gross monthly income that goes toward paying debts. Lenders use it to assess how much additional debt you can handle. A lower DTI shows lenders you have a healthy balance between income and debt.

Front-end vs. back-end DTI

The front-end ratio (or housing ratio) includes only your housing costs — mortgage principal and interest, property taxes, homeowners insurance, and HOA fees. Most lenders want this below 28%. The back-end ratio includes all monthly debt obligations. Most lenders want this below 36–45%.

How to lower your DTI

The fastest ways are to pay off smaller debts entirely (which removes their monthly payment from your DTI), avoid taking on new debt before applying, or increase your income. You can also choose a less expensive home to reduce your housing payment. Our debt payoff calculator can help you prioritize which debts to eliminate first.

DTI and mortgage qualification

Your DTI is one of the most important factors in mortgage approval. Use this alongside our mortgage calculator and affordability calculator to find a home price that keeps your DTI in lender-friendly territory.

Frequently asked questions

What is a good debt-to-income ratio?

Most lenders prefer a back-end DTI of 36% or lower. Conventional loans allow up to 45%, and FHA loans may go up to 57%. A front-end DTI under 28% is considered excellent.

What DTI do I need to qualify for a mortgage?

Conventional loans typically require a back-end DTI of 45% or lower. FHA loans allow up to 57%. VA and USDA loans generally prefer under 41% but have some flexibility.

How do I lower my DTI quickly?

Pay off small debts entirely, avoid new debt, increase income, or choose a less expensive home. Paying off a $200/month car loan can drop your DTI by several percentage points.

Does student loan debt affect DTI?

Yes. Lenders count your required monthly student loan payment in your DTI. If your loans are in deferment, some lenders still estimate a payment (often 0.5–1% of the balance per month) for qualification purposes.
