Contractor DTI Calculator: Assess Your Home Loan Readiness

If this DTI percentage fits within your financial goals, you likely have a strong baseline to start the application process—your next step is a soft-pull rate check to see how your specific business income holds up against current market offerings. Keep in mind that your final qualifying rate and approval status will depend heavily on your credit profile and the specific documentation type you choose.

What changes your rate / answer

• Income Documentation Method: If you use a bank statement mortgage, lenders look at your deposits rather than your net income after write-offs, which can drastically lower your calculated DTI.
• Business Write-offs: Traditional loans count your net profit after deductions, but choosing a no-tax-return loan allows you to bypass the penalty of aggressive tax planning.
• Existing Debt Load: Paying down high-interest business equipment loans or credit lines before applying can improve your ratio without needing to increase your income.
• Credit Score: A score above 720 often opens the door to more flexible DTI limits, even if your income stream is seasonal or irregular.

How to use this

• Gross Monthly Income: Use your pre-tax business income if applying for a conventional loan, or your average monthly deposits if opting for an alternative documentation program.
• Total Monthly Debt: Be sure to include all revolving credit, vehicle payments, and other recurring obligations shown on your credit report; exclude utility bills.
• Interpreting the Result: A result below 36% is ideal for conventional financing; if you fall between 40% and 50%, you may want to review our contractor home loan requirements 2026 to see if you qualify for non-QM programs.
