FHA Debt-to-Income Ratio Limits

Updated October 20, 2026 · Hyde Funding

FHA debt-to-income ratio limits for manually underwritten loans are set at 31/43 for most borrowers, with possible increases to 37/47 or 40/50 when specific compensating factors are documented.

FHA Debt-to-Income Ratio Limits for Manually Underwritten Loans

FHA loans rely on two primary ratios during manual underwriting to evaluate a borrower’s ability to manage housing costs alongside other financial obligations. The Total Mortgage Payment to Effective Income Ratio, often called the housing ratio, measures the portion of effective income devoted to the full mortgage payment. The Total Fixed Payments to Effective Income Ratio, commonly referred to as the DTI ratio, incorporates the full mortgage payment plus all recurring monthly debts and liabilities.

The total fixed payment consists of the complete mortgage payment—principal and interest calculated at the note rate, taxes, insurance, and any escrow items—combined with monthly obligations on all debts and liabilities listed on the credit report, loan application, and supporting documents. HUD policy requires that every applicable liability be included unless specific exclusions apply.

Approvable Ratio Requirements (Manual)

Ratio Limits by Credit Score

HUD establishes maximum qualifying ratios that adjust according to the borrower’s minimum decision credit score. Borrowers with scores between 500 and 579, or those with no credit score, are limited to 31/43 ratios. Borrowers scoring 580 and above begin at the 31/43 baseline but may qualify for higher ratios when acceptable compensating factors are documented.

For borrowers without credit scores, only income from occupying borrowers obligated on the mortgage is used to calculate ratios. Non-occupant co-borrower income cannot be included in these calculations.

The matrix of approvable ratios shows that 580-and-above borrowers may reach 37/47 with one compensating factor, 40/50 with two compensating factors, or 40/40 in certain documented scenarios. Energy Efficient Homes may use stretch ratios of 33/45 without additional compensating factors in applicable cases.

Acceptable Compensating Factors

When ratios exceed base limits, underwriters evaluate compensating factors that demonstrate the borrower can still handle the payment. Verified and documented cash reserves equal to at least three monthly payments, a minimal increase in housing payment compared with current costs, residual income remaining after obligations, significant additional income not already counted in effective income, and the absence of discretionary debt are among the factors considered.

Documentation requirements for these factors are detailed in HUD guidance. Energy Efficient Homes qualify for the 33/45 stretch ratios when the home meets ENERGY STAR standards, supported by manufacturer invoices for new homes or photos of the ENERGY STAR label for existing homes.

Required Documentation for Acceptable Compensating Factors

How Ratios Are Calculated

Underwriters must review every monthly liability appearing on the credit report, Uniform Residential Loan Application, and supporting documents. Closed-end debts scheduled to be paid off within ten months and totaling five percent or less of gross monthly income may be excluded. Thirty-day accounts are omitted from the DTI if the borrower has paid the balance in full each month for the prior twelve months. Contingent liabilities, such as co-signed debts, are counted unless the primary obligor demonstrates timely payments.

Material inquiries on the credit report must be examined to ensure any resulting new debt payments are incorporated. The underwriter also confirms that recent debts were not incurred to obtain funds for closing.

Evaluating Liabilities and Debts (TOTAL)

Manual Underwriting Process

All FHA loans are first processed through TOTAL Mortgage Scorecard. When the scorecard returns a Refer decision or the loan is manually downgraded, the underwriter applies the manual ratio requirements. The process includes verifying income, assets, and credit; confirming that any ratio exceptions are supported by documented compensating factors; and resolving all inconsistencies before approval. The underwriter must document resolutions and report any misrepresentations or fraud.

The lack of traditional credit history alone cannot serve as the basis for denial, and compensating factors cannot offset derogatory credit.

Step-by-Step Process for Borrowers Preparing for Ratio Review

Borrowers can follow a structured approach to prepare documentation and improve the likelihood of meeting FHA standards. First, obtain a current credit report and review every account for accuracy. Second, compile twelve months of payment history on revolving and installment accounts. Third, gather bank statements showing reserves after closing costs and any gifts. Fourth, list every recurring monthly obligation, including child support, alimony, lease payments, and authorized-user accounts. Fifth, confirm that the credit report contains no recent material inquiries that could create new debt. Sixth, work with the lender to determine whether any debts can be paid down before closing without violating the ten-month exclusion rule. Seventh, verify that all income sources are supported by the required documentation, such as W-2s, tax returns, or employer verification.

Documents Checklist

A complete file typically includes twelve months of canceled checks or bank statements for rental history, payoff statements for debts paid at or before closing, payment arrangements for collections when applicable, and evidence of reserves after all closing costs. Borrowers should also provide the most recent statements for all revolving and installment accounts, documentation of any contingent liabilities showing the primary obligor’s payment history, and verification that thirty-day accounts have been paid in full for the past year.

Worked Example of Ratio Calculation

Consider a hypothetical borrower with $6,000 in gross monthly effective income. The proposed total mortgage payment is $1,800. Additional monthly obligations total $900. The housing ratio is calculated as $1,800 divided by $6,000, resulting in 30 percent. The DTI ratio is calculated as $2,700 divided by $6,000, resulting in 45 percent. If the borrower’s credit score is 580 or higher and one or more compensating factors—such as documented reserves equal to three monthly payments—are verified, the underwriter may approve the ratios under the expanded limits. All figures are illustrative and exclude actual rates or payments.

Common Mistakes

Borrowers sometimes overlook authorized-user accounts that must be included in the DTI. Others attempt to exclude closed-end debts without confirming they meet both the ten-month and five-percent thresholds. Failing to document compensating factors fully or leaving inconsistencies between the credit report and application unresolved can delay or prevent approval. Another frequent error is assuming non-occupant co-borrower income can offset ratios for borrowers without credit scores.

How FHA Manual Ratios Compare to Alternatives

FHA manual underwriting applies the ratio matrix and compensating-factor requirements described above when TOTAL Scorecard issues a Refer decision. Other loan programs may use different automated systems or ratio guidelines, but FHA remains distinctive in its explicit allowance for documented compensating factors and its treatment of Energy Efficient Homes. Borrowers should review all available options with their lender to determine which program aligns with their documented income, assets, and credit profile.

Frequently asked questions

What is the standard FHA DTI limit for manual underwriting?

The base limit is 31 percent for the housing ratio and 43 percent for the total DTI. These apply to borrowers with credit scores of 500 and above when no compensating factors are used.

Can FHA ratios be exceeded with compensating factors?

Yes. With one or more documented compensating factors, ratios may reach 37/47 or 40/50 depending on the credit score and factors provided, such as reserves or residual income.

How does TOTAL Scorecard affect ratio requirements?

TOTAL Scorecard is used first. If it returns Refer or the loan is manually downgraded, the underwriter applies the manual ratio matrix and compensating factor rules from the FHA handbook.

Are non-occupant co-borrowers counted in DTI calculations?

Non-occupant co-borrower income is excluded when the occupying borrower has no credit score. Only income from occupying borrowers on the note is used for ratio calculations.

What documentation supports compensating factors?

Reserves require bank statements showing funds after closing. Minimal payment increase needs current and proposed housing payment verification. Residual income uses a detailed monthly budget analysis.
