Measure entered monthly debt payments against gross monthly income.
It turns the values and assumptions you choose into a transparent planning result. It does not import financial accounts, guess missing household information, or decide what is suitable for you.
The relationship
Follow the money, rate, and time basis
Debt-to-income ratio = total monthly debt payments ÷ gross monthly income × 100%.

Read the result
Keep the result inside its assumptions
Monthly debt payments of 2,000 and gross monthly income of 6,000 produce a debt-to-income ratio of 33.333…%.
This is the common gross-income DTI definition. Which obligations count and what ratio is acceptable vary by lender, product, and jurisdiction; no approval threshold is applied.

Calculation method
Calculation method
Debt-to-income ratio = total monthly debt payments ÷ gross monthly income × 100%.
Entered decimals are combined with exact integer-and-rational arithmetic. Results round to two decimal places for ordinary money display, while a smaller nonzero value remains visible instead of being shown as zero. Repeating percentage digits appear in parentheses; an ellipsis marks a decimal expansion longer than the 12-place preview.
