How to Use the DTI Calculator

Enter your gross income (annual salary or monthly), then add each of your monthly debt payments. The calculator instantly computes your front-end DTI (housing costs only) and back-end DTI (all debts). Use the visual gauge to see where you land relative to common lender thresholds, and check the recommendations section to learn exactly how much debt to eliminate to reach your target ratio.

Understanding the DTI Zones

Green (below 36%) — You are in excellent shape for most loan types.
Yellow (36% - 43%) — Acceptable for FHA and some conventional loans, but reducing debt will improve your rate.
Red (above 43%) — Most lenders will consider this too high. Focus on paying down debts or increasing income before applying.

Frequently Asked Questions

What is a debt-to-income (DTI) ratio?+

Your debt-to-income ratio is the percentage of your gross monthly income that goes toward paying debts. Lenders use it to gauge your ability to manage monthly payments and repay borrowed money. A lower DTI means less risk to lenders and more borrowing power for you.

What is the difference between front-end and back-end DTI?+

Front-end DTI (also called the housing ratio) only includes housing-related costs like mortgage or rent. Back-end DTI includes all recurring monthly debts: housing, car payments, student loans, credit cards, child support, and any other obligations. Lenders evaluate both, but back-end DTI is typically the deciding factor.

What is a good debt-to-income ratio for a mortgage?+

For a conventional mortgage, lenders prefer a front-end DTI of 28% or less and a back-end DTI of 36% or less. FHA loans allow up to 43% back-end (sometimes 50% with compensating factors). VA loans have a guideline of 41% back-end but no strict front-end limit. Generally, keeping your DTI below 36% gives you the most options.

How can I lower my debt-to-income ratio?+

You can lower DTI by paying down existing debts (especially high-payment ones like car loans or credit cards), increasing your income, avoiding new debt, or refinancing to lower monthly payments. Even paying off a single debt can significantly improve your ratio and mortgage eligibility.

Does DTI affect my credit score?+

DTI itself does not directly appear on your credit report or affect your credit score. However, the factors that cause high DTI — like high credit card balances — do impact your credit utilization ratio, which is a major credit score factor. Reducing debt improves both your DTI and your credit profile.

Is gross or net income used for DTI calculations?+

Lenders use gross income (before taxes and deductions) when calculating DTI. This is your total pre-tax salary, not your take-home pay. Self-employed borrowers typically use adjusted gross income from tax returns. This calculator uses gross monthly income for accurate lender-comparable results.
