Debt-to-Income Calculator 2026 — FHA & Conventional Benchmarks
See your front-end and back-end debt-to-income ratio compared against real FHA and Conventional guidelines, including the stretch thresholds strong files can sometimes reach.
Debt-to-income (DTI) ratio compares your monthly debt payments to your gross monthly income. FHA underwriting leads with a 43% standard back-end benchmark, with a stretch to roughly 56.99% possible through automated underwriting for well-qualified files. Conventional loans generally use a 45% standard benchmark with a stretch to about 50% for strong files. This calculator compares your front-end and back-end ratios to each program.
- ✓Front-end DTI compares only your housing payment to gross income; back-end DTI adds every other monthly debt.
- ✓FHA leads with a 43% standard back-end benchmark, with an AUS stretch to approximately 56.99% for strong files.
- ✓Conventional loans generally use a 45% standard benchmark with a stretch to about 50% for well-qualified borrowers.
- ✓Compensating factors like reserves, high credit scores, and minimal payment shock can support approval above the standard line.
- ✓Lowering revolving balances or adding documented income are the fastest ways to improve your ratio before applying.
What this means for you: a DTI above the standard benchmark does not automatically disqualify you, but it does require stronger compensating factors and closer underwriting review.

Assumptions, methodology, and limitations
Debt-to-income equals total monthly debt payments (proposed housing payment plus recurring obligations) divided by gross monthly income, matching the front-end and back-end ratios underwriters review.
It excludes income documentation requirements, automated underwriting overlays, non-recurring debts, and residual-income tests used on some programs.
Results are illustrative estimates only and are not a quote, lock, offer, or commitment to lend. No rate, APR, or program approval is implied. Binding figures appear on your Loan Estimate. Eligibility, terms, and availability vary by borrower, property, lender, loan program, and state.

What debt-to-income ratio actually measures
Debt-to-income ratio, or DTI, is one of the core numbers underwriters use to judge whether a new mortgage payment fits comfortably within your monthly budget. It is expressed as a percentage: your total monthly debt obligations divided by your gross (pre-tax) monthly income. Lenders calculate two versions of this ratio, and both matter for different reasons during underwriting.
Front-end DTI versus back-end DTI
Front-end DTI includes only your proposed housing payment — principal, interest, taxes, insurance, mortgage insurance if applicable, and HOA dues — divided by gross monthly income. Back-end DTI takes that same housing payment and adds every other minimum monthly debt payment: credit cards, auto loans, student loans, personal loans, and support obligations like alimony or child support. Back-end DTI is generally the more important number in underwriting because it captures your full financial picture, not just the new housing cost.
FHA debt-to-income guidelines
FHA underwriting leads with a 43% standard back-end DTI benchmark. Through the FHA TOTAL Scorecard automated underwriting system, files with strong compensating factors — verified cash reserves, minimal increase between current housing cost and the new payment, stable long-term employment, or additional documented income — can sometimes be approved with a back-end DTI as high as approximately 56.99%. This stretch is conditional and evaluated case by case; it is not a guaranteed ceiling for every borrower.
Conventional debt-to-income guidelines
Conventional loans underwritten to conforming guidelines generally use a 45% standard back-end DTI benchmark. With strong compensating factors documented and run through automated underwriting, that ceiling can stretch to approximately 50% for well-qualified borrowers. Compared with FHA's wider stretch range, conventional guidelines tend to be somewhat less flexible on DTI, but often more flexible on credit-related pricing depending on the borrower's overall profile.

A short request is all it takes to get a written scenario summary back from a Simply Approved Mortgages Loan Officer. Binding figures appear on your Loan Estimate.
What counts as debt in the back-end calculation
Recurring monthly obligations reported on your credit report generally count: minimum credit card payments, auto loans, personal loans, and student loans. Student loans deserve special attention — when a credit report shows a $0 payment because a loan is deferred or on an income-driven repayment plan, lenders typically apply a small percentage of the outstanding balance as a placeholder payment rather than using the reported $0. Utilities, groceries, subscriptions, and voluntary retirement contributions are not counted as debt for DTI purposes.
Compensating factors that support a higher DTI
Underwriters look beyond the raw percentage when a file is above the standard benchmark. Verified reserves — liquid assets remaining after closing, often measured in months of the new payment — are one of the strongest compensating factors. Others include minimal payment shock (the new payment is close to what you already pay for housing), a long history in the same line of work, and a credit profile with limited recent derogatory events. No single factor guarantees approval; underwriters weigh the complete file together.
How to improve your DTI before applying
Paying down revolving balances lowers the minimum payment counted against you and can meaningfully improve back-end DTI within a single billing cycle once the lower balance reports. Avoiding new credit accounts or large purchases before closing prevents new payments from being added to the calculation at the worst possible time. Documenting additional income sources, such as consistent overtime, bonus, or a side business with a two-year history, can also raise the income side of the ratio rather than only reducing the debt side.
How a Simply Approved Mortgages Loan Officer helps
This calculator gives you an honest starting point, but a full DTI review requires your actual credit report, verified income documentation, and the specific loan program guidelines that apply to your file. A Simply Approved Mortgages Loan Officer can review your complete scenario, identify compensating factors that may help, and outline realistic next steps.

Compare loan officer compensation on your mortgage quote
Loan officer compensation is part of the cost of a mortgage. On eligible residential loans, Simply Approved Mortgages generally uses 1.5% lender-paid compensation. Enter the compensation shown on another lender's Loan Estimate to see the difference in dollars.
Compensation difference on this illustration: $3,750.
How lower compensation can help you
When less compensation is built into pricing, there can be room for a lower interest rate, which may lower your monthly payment.
Depending on the rate you choose, pricing can sometimes include a lender credit toward third-party closing costs, so you may bring less cash to closing.
A lower rate means a lower monthly payment, which can lower your debt-to-income ratio and may help you qualify for more home on the same income.
As a mortgage broker we compare pricing from wholesale lenders instead of offering a single bank’s retail pricing.
Tip: On page 2 of your Loan Estimate, look at Section A, "Origination Charges." If the lender pays the loan officer, that compensation usually does not appear there as its own line; it is built into the interest rate. That is why comparing the rate and any lender credits side by side matters.
Already have a Loan Estimate from another bank or broker? Share it with a Simply Approved Mortgages Loan Officer, who will compare the rate, fees and credits side by side with options we can arrange. No cost to request a review.
Illustration only — not a quote, lock, offer, or commitment to lend; binding figures appear on your Loan Estimate. Lender-paid compensation is paid by the lender, not directly by you, and is part of the loan's pricing, so the loan is not free of costs. A lower compensation figure does not by itself guarantee a lower rate or lower closing costs; individual results vary by credit, loan type, property and market conditions.

Assumptions, methodology, and limitations
Principal and interest use the standard amortization formula on the loan amount you enter. This page does not target a single state, so the property tax and insurance fields start at neutral placeholder assumptions rather than published averages — replace them with figures for your own address, or open the matching state page for sourced seeds. Closing costs apply your state's transfer / documentary-stamp practice (0.00% of price used as the buyer-side seed) plus typical title, recording, appraisal, credit and prepaid escrow lines. Refinance break-even divides your entered costs by the monthly payment difference. Early payoff runs a month-by-month amortization with your extra principal.
These tools do not include mortgage insurance, funding or guarantee fees, HOA special assessments, flood or windstorm premiums, seller credits, lender credits, discount points, or county and municipal charges specific to your parcel. Statewide averages will not match any individual property. Figures are estimates only.
