What is DTI?
Your DTI (Debt-to-Income ratio) is how lenders measure how much of your monthly income goes toward paying debts.
At MortgageMax, we use this number to help you understand how much home you can realistically afford—before you even apply.
How is DTI calculated?
DTI compares your total monthly debt payments to your gross monthly income (before taxes).
There are two main types:
✔ Front-end DTI:
Includes only your estimated housing payment (mortgage, taxes, and insurance).
✔ Back-end DTI:
Includes your housing payment plus all other monthly debts, such as:
Credit cards
Auto loans
Personal loans
Any other fixed payments reported on your credit report
The back-end DTI is the one most lenders—including MortgageMax—use to evaluate your loan eligibility.
Practical example
Let’s say your monthly income is $4,000.
Your monthly debts:
Estimated mortgage: $1,000
Car payment: $300
Credit cards: $200
Total monthly debt: $1,500
DTI is calculated by dividing your total debts by your income:
DTI = $1,500 ÷ $4,000 = 0.375 → 37.5%
This means 37.5% of your monthly income goes toward debt payments.
Why is DTI so important?
DTI answers a key question for lenders:
“Can this person afford a new mortgage without struggling each month?”
✅ A lower DTI shows you have room in your budget
⚠️ A higher DTI may signal financial strain to lenders
What should your DTI be?
Limits vary depending on the loan type, but generally:
Conventional loans: typically up to 45%
FHA loans: can go up to ~55% in some cases
VA & USDA loans: usually between 41%–50%, depending on your profile
As a best practice, aim to keep your DTI below 40%
The lower your DTI, the better your chances of approval—and better loan terms.
🧩 Tips to improve or maintain a healthy DTI
✔ Pay down small debts or credit card balances before applying
✔ Avoid financing large purchases before closing
✔ Make sure all stable income (bonuses, commissions) is documented
✔ Create a budget so you know what you can comfortably afford
