Free Debt-to-Income Calculator

What is a debt-to-income calculator?

Debt-to-income ratio shows how much of your monthly income is already committed to debt payments.

Enter monthly income and total monthly debt payments to calculate DTI percentage and remaining non-debt income.

DTI = Monthly debt payments ÷ Monthly income

DTI is widely used in lending decisions and is a useful budget stress metric.

Monthly take-home income is $5,500 and monthly debt payments are $1,650.

Line item	Amount	Calculator field
Monthly income	$5,500	Monthly income ($)
Monthly debt payments	$1,650	Monthly debt payments ($)

Debt-to-income ratio is 30%, leaving $3,850 for all other categories.

Lower DTI generally means more flexibility and lower risk.

Debt-to-income ratio — Share of income committed to monthly debt obligations.
Income left after debt — Monthly income remaining after debt payments.
DTI band — Simple low/moderate/high classification for budgeting context.

DTI is one signal, not the full picture. Pair it with savings rate and emergency fund progress.

Include recurring monthly obligations like credit cards, loans, and required installment payments.

For personal budgeting, net income is practical. Lenders often use gross income.

Lower is generally safer; exact thresholds depend on goals and lender rules.
