How to use this calculator

Open the short walkthrough for choosing and checking inputs.

The calculator adds the entered housing and other required monthly debt payments, divides that total by gross monthly income, and multiplies by 100. It floors the maximum payment at the selected target to a whole cent so the inverse result does not exceed the target.

Calculation details

Formula and methodology

See the exact math used to produce the result.

Debt-to-income ratio = required monthly debt payments divided by gross monthly income, multiplied by 100. Maximum payment = gross income multiplied by the selected planning target.

Before acting

Assumptions to check

Review the real-world details that can change the estimate.

The key inputs are Gross monthly income, Monthly housing payment, Other monthly debt payments, Planning DTI target. Use gross monthly income and the obligations relevant to the decision. The selected percentage is a planning target only; lenders and products can count qualifying income, housing expense, and debt differently.

When to round up

The displayed ratios round to two decimal places, but target status is determined from cents and basis points. Lenders and loan products can count qualifying income, housing expense, and debt obligations differently, so use the target only as a planning scenario.

When to use this calculator

  • Checking current required debt payments against gross income
  • Working backward from a user-selected planning target
  • Preparing questions about which obligations a lender will count

Tips for better estimates

  • Use the actual APR and loan term when available.
  • Add taxes, insurance, fees, PMI, HOA, or maintenance when they apply.
  • Treat the result as a planning estimate, not approval or a quote.

How this calculator is reviewed

This page is checked for inputs, formulas, examples, assumptions, topic fit, and related links. For this calculator, the review also covers balance, APR, payment amount, compounding, fees, taxes, payment timing, and estimate limits.

The sample result is covered by automated tests, and the page links to related calculators and, where available, supporting guides so readers can check the assumptions before acting. If a formula, label, or assumption looks off, send the page URL and your inputs through the contact page.

How this estimate was built

This page converts income and required monthly obligations to cents, calculates the ratio, and floors the inverse maximum payment to cents so it does not exceed the selected planning target. The target is never presented as lender approval.

Worked example

Example inputs: Gross monthly income: $6000; Monthly housing payment: $1500; Other monthly debt payments: $500; Planning DTI target: 36 %. With those values, the calculator returns 33.33% debt-to-income ratio. The entered monthly debt payments leave $160.00 of mathematical room at the selected 36% planning target. This is not an approval estimate.

Example scenarios

  • $2,000 of required monthly debt payments divided by $6,000 of gross monthly income is a 33.33% debt-to-income ratio.
  • At a user-selected 36% planning target, that example has a mathematical maximum total debt payment of $2,160 and $160 of remaining monthly room.
  • A lender may count qualifying income and obligations differently, so the result is not a universal limit, approval, or underwriting decision.

FAQs

Debt-to-Income Ratio Calculator questions

What is a debt-to-income ratio?

It is total required monthly debt payments divided by gross monthly income. Lenders use it as one part of evaluating whether monthly obligations appear manageable.

Is 36% a universal approval limit?

No. Different lenders, loan products, and underwriting methods use different limits and can count income or obligations differently.

What belongs in monthly debt payments?

Use the obligations relevant to the decision, such as housing, installment loans, revolving minimums, leases, and other required payments. Confirm the exact treatment with the lender.

Does the maximum payment result guarantee approval?

No. It is the mathematical amount at the selected planning target, not underwriting, prequalification, approval, or financial advice.
