What Is the Debt-to-Income Ratio Calculator?

Debt-to-income ratio (DTI) compares how much of your gross monthly income goes toward debt payments. Lenders use it to judge how much additional debt — like a mortgage — you can comfortably handle.

Formula

DTI (%) = (Total Monthly Debt Payments ÷ Gross Monthly Income) × 100. Most mortgage lenders prefer a DTI at or below 36%, and many loan programs cap it around 43%.

How to Use This Calculator

Worked Example

Someone earning $6,000 a month with $1,800 in combined debt payments has a DTI of 30% (1,800 ÷ 6,000 × 100), which falls in the “Good” range for most lenders.

Tips

Paying down credit cards or consolidating high-payment loans is usually the fastest way to lower your DTI, since it directly reduces the numerator of the ratio.
