Debt-to-income ratio calculator
Use gross monthly income, housing cost, and other recurring debt payments to estimate front-end and back-end DTI ratios quickly.
Why this result matters
A lender-style approval-readiness tool for quickly measuring housing-only and total debt load versus income. Use the tool above to enter a few clear inputs and get a practical answer you can use right away.
This debt-to-income ratio calculator helps borrowers see how much of their gross monthly income is already committed to debt. It separates housing payment from other recurring obligations so users can compare front-end DTI, back-end DTI, and the amount of income left after debt payments. That makes it useful for mortgage prep, refinancing checks, and broader approval-readiness planning.
Formula and method
The calculator divides housing payment by gross monthly income for front-end DTI, then divides total monthly debt payments by gross monthly income for back-end DTI. It also shows income left after debt obligations and a simple interpretive band.
Example
If you earn 8,500 per month before taxes, spend 2,200 on housing, and carry 950 in other monthly debt, the calculator estimates both the housing-only ratio and the total debt-to-income ratio lenders often review.
FAQ
Short answers to the questions people often ask before or after using the tool.
Question
Front-end DTI looks only at housing cost versus gross monthly income. Back-end DTI includes housing plus other recurring monthly debts like auto loans, student loans, or credit-card minimums.
Question
Because many lenders use DTI as a quick way to judge whether a borrower has enough income to handle new debt on top of existing obligations.
Question
No. This is a planning estimate only. Credit score, assets, reserves, employment history, loan type, and lender rules can all affect final approval.
