Debt to Income ratio to Buy a House calculator

By comparing your total monthly debt with your income, it shows whether you can afford a house and if you meet typical lender requirements for mortgage approval.

How to use this calculator

Enter your gross monthly income (before tax). Then add your expected housing payment (including mortgage, taxes, insurance, and HOA if any). After that, enter your other monthly debts like car loans, credit cards, or student loans.

The calculator will instantly show your front-end DTI (housing only) and back-end DTI (total debt). These numbers help you understand if you can afford a house and whether you meet typical lender requirements.

Formula used

This calculator uses two main formulas:

● Front-End DTI (Housing Ratio)
= (Monthly Housing Payment ÷ Gross Monthly Income) × 100
● Back-End DTI (Total Debt Ratio)
= (Monthly Housing Payment + Other Debts ÷ Gross Monthly Income) × 100
The back-end DTI is the most important one, as lenders use it to decide your mortgage eligibility.

FAQ

3. Does DTI affect mortgage approval? ● Yes, DTI is one of the most important factors lenders use to approve or reject your loan.

4. Can I get a loan with a high DTI? ● It’s possible, but harder. You may need a higher credit score, larger down payment, or a co-applicant.

5. What counts as debt in DTI? ● Car loans, credit card payments, student loans, personal loans, and any fixed monthly obligations are included.
