For DTI, should you enter debt balances or monthly payments?
Debt-to-income ratio measures monthly payment obligations, not the sum of every outstanding loan balance. The input needs to match the monthly cash-flow definition.

An outstanding balance describes how much principal remains at a point in time. A monthly payment describes money due during one month. Entering a balance in a payment field produces a ratio with the wrong meaning. Housing debt entered in its own field should also not be repeated under other debt, because that would double-count the same obligation.
Add the relevant monthly amounts
Suppose a mortgage balance is 180,000 but its monthly payment is 1,000. Add a car-loan payment of 250 and other monthly debt payments of 150, with gross monthly income of 4,000. The ratio is (1,000 + 250 + 150)/4,000 = 35%. The 180,000 balance does not replace the mortgage’s 1,000 payment in this calculation.
Check the lender’s required categories separately
An underwriting process may require particular housing-related charges or a specified method for credit-card obligations. The site simply adds the housing-debt and other-debt amounts you supply; it does not import a credit report or decide every lender’s inclusion rules. Assemble the items required for your purpose, then use the calculator to verify the total and ratio. The result remains a calculation rather than an approval decision or a complete household spending analysis.
