DTI

How do I calculate DTI for a conventional loan?

Short answer

Add the proposed housing payment and other required monthly debt payments. Divide that total by your qualifying monthly income before taxes, then multiply by 100.

Plain-English explanation

What this actually means.

Housing includes principal and interest, property taxes, insurance, mortgage insurance and applicable association dues. Count any CDD charge once, including when it is already in the tax bill. Student loans and some other debts have program-specific rules. The lender must verify which income can be used. DTI does not include every living expense, so check your take-home budget too.

Practical example

A simple example

An assumed full housing payment of $2,200 plus $500 in other counted monthly debts totals $2,700. Divide $2,700 by $6,000 of qualifying monthly income: 0.45, or 45% DTI. These assumed figures are not a mortgage quote or an approval.

Illustration only. This is not an approval or a loan offer.

What can change the answer?

Where this can move.

Verified income, actual taxes and insurance, association or CDD charges, program-specific debt treatment and new debts before closing.
