Does DTI include my mortgage payment?

Yes, the back-end DTI calculation includes your proposed new mortgage payment along with existing car loans, student loans, and minimum credit card payments.

What debts are excluded from the DTI calculation?

Buyer's guide

How to choose a debt-to-income ratio calculator

When picking a DTI calculator, the numbers you enter matter more than the design: you need accurate monthly debt totals and gross monthly income to get a meaningful percentage. If you are shopping for a mortgage, look for a tool that shows both front-end (housing-only) and back-end (all debts) ratios, since lenders use both figures. Differences worth caring about include whether the tool explains what the percentage means for loan approval, whether it estimates how much house you can afford, and how many debt categories it accepts (student loans, car payments, credit cards, etc.).
