What is a good debt-to-income ratio?

Generally, a DTI below 36% is considered healthy, with no more than 28% going toward housing. Lenders often prefer ratios under 43% for mortgage approval, but thresholds vary by loan type and lender.

Does this calculator use take-home pay or gross income?

This tool uses gross income (before tax) as the denominator, which is standard for DTI calculations, especially those used by lenders.

Can I use this calculator to determine how much house I can afford?

Yes, the site provides a linked House Affordability Calculator that uses your DTI inputs to estimate a price range, though actual affordability depends on additional factors like down payment and credit score.

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

The front-end ratio compares housing costs (mortgage, tax, insurance) to gross income, while the back-end ratio includes all monthly debt payments divided by gross income. This calculator provides both figures.

What Debt-to-Income Ratio Calculator does

A Debt-to-Income (DTI) Ratio Calculator that determines both front-end and back-end ratios by comparing gross income against monthly debt obligations. Users input income sources—salary, pension, investment returns, and other earnings—and monthly expenses including rent, mortgage, property taxes, credit cards, student loans, auto loans, and other liabilities. The output provides the calculated DTI percentages, offering a clear snapshot of debt load relative to earnings to assess financial stability. The site also includes a linked House Affordability Calculator for extended planning. What sets Calculator.net apart is its granular input fields for both income and expense categories, presented in a simple month/year format. While other DTI tools exist, this version explicitly separates front-end (housing-related) from back-end (total debt) ratios and includes a dedicated section explaining the metric's importance to lenders, all without requiring sign-up or payment.
