Debt to Income DTI Calculator
Check how much of your income goes toward debt each month and see exactly how lenders view your approval chances.
Monthly Income
Total income before taxes or deductions.
Housing Costs (Front-End)
Include expected property tax, insurance, and HOA.
Other Debts (Back-End)
Your Borrowing Room
Lenders look at these two numbers to decide if you can afford a loan.
Front-End DTIHousing Only
Back-End DTITotal Debt
Approval Signal: Borderline / Moderate Risk
Your DTI is between 36% and 43%. Many lenders will still approve you, but you may face stricter credit or reserve requirements.
Know Your Borrowing Room
Your income tells one side of the story. Your debt tells the other.
A Debt to Income DTI Calculator helps you compare monthly debt payments with gross monthly income, so you can understand how lenders may view your ability to manage a mortgage, refinance, auto loan, or personal loan.
DTI Formula
DTI is simple:
DTI = Monthly Debt Payments ÷ Gross Monthly Income × 100
For example, if your monthly debts are $2,400 and your gross monthly income is $6,000, your DTI is 40%.
Front-End DTI
Front-end DTI looks at housing costs only.
This may include mortgage principal, interest, property taxes, homeowners insurance, PMI, and HOA fees. It shows how much of your income is dedicated strictly to keeping a roof over your head.
Back-End DTI & Debt Count
Back-end DTI includes housing plus all other recurring debts.
This is often the stronger number for loan planning because it shows your full debt load.
DTI usually focuses on recurring monthly debt on your credit report. Groceries, utilities, gas, subscriptions, and normal living costs affect your budget, but they are usually not treated the same as debt payments.
Key Debts to Include:
- Car loans
- Student loans
- Credit cards (min)
- Personal loans
- Alimony / Child support
Approval Signal
A lower DTI may show stronger repayment room.
A higher DTI does not always mean denial, but it can make approval harder or require stronger credit, savings, income, or loan terms. The "Approval Signal" inside the calculator above will warn you if your debt load is approaching standard lender limits.
Improve DTI
- Pay down existing debt
- Avoid taking out new loans
- Reduce credit card balances
- Choose a lower target mortgage payment
- Increase qualifying gross income

Quick Answers
What is a good Debt-to-Income (DTI) ratio?
Most lenders prefer a back-end DTI of 36% or less. This shows you have plenty of room in your budget to comfortably afford a new loan payment. However, some loan programs may allow a DTI up to 43%, or even 50% in special cases with strong compensating factors.
What is the difference between Front-End and Back-End DTI?
Front-End DTI only compares your housing costs (mortgage, property taxes, insurance, HOA) against your gross income. Back-End DTI includes your housing costs PLUS all other recurring debt payments like auto loans, student loans, and credit card minimums.
Do groceries or utility bills count toward my DTI?
No. Living expenses such as groceries, utility bills, streaming subscriptions, and cell phone plans are not typically factored into your DTI calculation. DTI only focuses on official debt obligations that show up on your credit report, plus housing costs and alimony/child support.
Should I use Gross or Net Income to calculate DTI?
You should always use your Gross Monthly Income, which is your total earnings before taxes and other paycheck deductions are taken out. This is the number lenders use to qualify you for a loan.
