Income and monthly debt payments

Income before taxes and deductions. Combine the income of everyone applying for the loan.

Switching the period converts the income amount automatically.

Add the required monthly payments for all vehicles.

Enter the total minimum payments due, not the balances on your cards.

Additional monthly debts $0.00/mo

A lender may count a payment even if your current payment is $0 or deferred. Use the lender's qualifying amount when available.

Include required payments for other installment loans.

Include ongoing court-ordered payments you make. A lender may treat certain obligations differently.

Add other recurring debts. For housing you will keep, ask a lender which payment amount to include. Count each debt only once.

This estimate is for planning, not a loan approval. Lenders verify eligible income and debts, and requirements vary by loan program. Your credit, savings, and other factors also matter. Real Deal Home Team does not provide loans.

How to calculate your debt-to-income ratio for a mortgage

Your DTI is your total required monthly debt payments divided by income before taxes, multiplied by 100. The housing-only ratio uses just your housing payment. Annual income is divided by 12.

A lower ratio means less of your gross income is committed to debt. There is no single approval cutoff for every mortgage. Utilities, groceries, childcare, and other living costs are not included in this calculation, but they still affect what you can comfortably afford. Self-employed or variable income may require a lender's adjustments.

If you are preparing to buy a home in Cincinnati or the surrounding communities, use this result alongside our mortgage calculator and home affordability calculator, then talk with Real Deal Home Team about your next step.

Debt-to-Income Ratio FAQs

What is a debt-to-income ratio?

Your debt-to-income ratio, commonly called DTI, is the percentage of your gross monthly income used for required monthly debt payments. Divide total monthly debt payments by gross monthly income, then multiply by 100.

What debts should I include in a DTI calculation?

Include the housing payment you expect to keep, vehicle loans or leases, credit card minimums, student and personal loans, and other recurring obligations. Count each debt only once and ask a lender how a specific obligation should be treated.

Does DTI include utilities and everyday expenses?

Utilities, groceries, childcare, transportation, and most everyday living expenses are generally not part of the DTI formula. They still matter when deciding what monthly housing payment feels comfortable.

Does this calculator provide mortgage approval?

No. This calculator is a planning tool. Mortgage lenders verify eligible income, debts, credit, assets, and loan-program requirements before making an approval decision.
