Front-End Ratio
The front-end ratio (also called the housing ratio) compares your monthly housing expenses to your gross monthly income. This includes your mortgage payment (principal, interest, taxes, and insurance).
Front-End DTI = Housing Expenses / Gross Income
Back-End Ratio
The back-end ratio (also called the total DTI) compares all your monthly debt payments to your gross monthly income. This includes housing expenses plus all other debts.
Back-End DTI = Total Debt / Gross Income

Tips to Improve Your DTI

Make extra payments on high-interest debt to reduce your monthly obligations.
Increase Income
Consider a side job, freelance work, or ask for a raise to boost your monthly income.
Consolidate Debt
Combine multiple debts into one payment with a lower interest rate.
Avoid New Debt
Don't take on new loans or credit card debt before applying for a mortgage.

A larger down payment reduces your loan amount and monthly payment.

Frequently Asked Questions
What is a debt-to-income ratio?
Your debt-to-income (DTI) ratio is the percentage of your monthly income that goes toward paying your debts. Lenders use this ratio to determine how much you can afford to borrow for a mortgage.
What is the 28/36 rule?
The 28/36 rule is a common guideline for mortgage affordability. It states that your housing expenses should not exceed 28% of your gross monthly income, and your total debt payments should not exceed 36% of your gross monthly income.
What is a good DTI ratio?
A DTI ratio of 36% or lower is generally considered good. Most lenders prefer a DTI below 43%, though some government-backed loans allow higher ratios with compensating factors.
What counts as debt for DTI?
Debt includes credit card payments, car loans, student loans, personal loans, child support, and any other recurring monthly payments. It does not include utilities, groceries, or other living expenses.
How can I improve my DTI ratio?
You can improve your DTI by increasing your income, paying off debts, or consolidating high-interest debt. Making extra payments on existing debts can also help lower your monthly payments.
What is the maximum DTI for a mortgage in 2026?
As of 2026, most conventional lenders require a DTI of 43% or lower. FHA loans may allow DTIs up to 50% with strong credit and other compensating factors.
Does DTI affect my interest rate?
Yes, a lower DTI can help you qualify for better interest rates. Lenders view lower DTIs as less risky, which may result in more favorable loan terms.
Is DTI based on gross or net income?
DTI is calculated using your gross monthly income (before taxes and deductions). This includes salary, bonuses, commissions, and other regular income sources.
Can I get a mortgage with a high DTI?
It is possible to get a mortgage with a high DTI, especially through government-backed programs like FHA or VA loans. However, you may face higher interest rates or stricter requirements.
Does rent count toward DTI?
If you currently rent, your rent payment is not included in your DTI calculation for a new mortgage. However, lenders will consider your housing expense ratio when approving your loan.
How do lenders calculate DTI for self-employed borrowers?
For self-employed borrowers, lenders typically use your net income from your tax returns (usually averaged over 2 years) to calculate your DTI.
What happens if my DTI is too high?
If your DTI is too high, you may be denied a mortgage or offered less favorable terms. You may need to pay down debt, increase your income, or save for a larger down payment.
