Formula and method

DTI = monthly debt payments ÷ gross monthly income × 100.

Example

Monthly debts of $1,800 divided by $6,000 of gross monthly income equals a 30% debt-to-income ratio.

What this calculator is useful for

Calculate your debt-to-income ratio by comparing monthly debt payments with gross monthly income. It is designed for quick estimates and everyday problem solving. When a calculation affects a contract, tax filing, medical decision or other high-stakes situation, verify the result with the appropriate professional or authoritative source.

Use gross monthly income, not take-home pay

With $2,100 in recurring monthly debt payments and $7,000 in gross monthly income, DTI = 2,100 ÷ 7,000 × 100 = 30%. Compare obligations and income over the same month.

What to check: Lender DTI definitions vary; housing expenses, proposed mortgage payments, alimony, and some other obligations may be included. Utilities and groceries are usually budget expenses, not DTI debts.

Compare with the Loan Payment calculator when that better matches the question you are trying to answer.
