How This Calculator Works

Use this debt-to-income tool for quick estimation, comparison, and planning intent while keeping formula assumptions visible.

Use the debt-to-income ratio calculator to estimate how much of your gross monthly income goes to recurring debt payments.

DTI compares recurring monthly debt payments with gross monthly income before taxes.

Formula

Debt-to-income ratio = monthly debt payments / gross monthly income x 100.

Example Calculation

$2,630 in monthly debt on $6,500 gross income equals a DTI of about 40.5%.
