What is a good debt-to-income ratio?

For conventional loans, lenders want a front-end DTI below 28% and a back-end DTI below 36%. FHA loans allow up to 31%/43%. Below 36% back-end DTI is considered good; below 28% is excellent. Above 43% makes mortgage approval difficult with most lenders.

What is the difference between front-end and back-end DTI?

Front-end DTI (housing ratio) = housing costs ÷ gross income. It includes mortgage/rent, property tax, homeowners insurance, and HOA. Back-end DTI (total debt ratio) = all monthly debt payments ÷ gross income. It adds car loans, student loans, credit cards, and other debts on top of housing.

How do I lower my DTI ratio to qualify for a mortgage?

Three strategies: (1) Increase income — a raise, side income, or adding a co-borrower. (2) Pay down debt — eliminate credit card balances and car loans to reduce minimum payments. (3) Choose a less expensive home — lower purchase price reduces mortgage payment and front-end DTI directly.

Does DTI affect my interest rate?

DTI doesn't directly affect your rate (credit score and LTV do), but it affects approval. A high DTI may limit you to FHA or VA loans, which can have different rates and PMI requirements. Getting your back-end DTI below 36% opens you to the best conventional loan rates.

Debt-to-Income Ratio Calculator

Front-end & back-end DTI with loan approval outlook — 2026

Your debt-to-income (DTI) ratio is the single most important number lenders check when you apply for a mortgage. Conventional lenders require a front-end DTI ≤ 28% (housing costs ÷ income) and back-end DTI ≤ 36% (all debts ÷ income). FHA loans allow up to 43% back-end; VA/USDA up to 41%. This calculator computes both ratios, shows your approval odds across all three loan types, and tells you exactly how much additional debt capacity you have before hitting each limit.

How DTI Is Calculated

Lenders calculate two separate DTI ratios. The front-end ratio (housing ratio) only includes your housing-related expenses — PITI (principal, interest, taxes, insurance) plus HOA. The back-end ratio (total debt ratio) includes all monthly debt obligations: housing costs plus car loans, student loans, credit card minimums, and any other recurring debt. Both are divided by gross monthly income (before taxes).

Front-End DTI = (Housing Costs) ÷ Gross Monthly Income × 100

Back-End DTI = (All Monthly Debts) ÷ Gross Monthly Income × 100

Loan Type	Max Front-End	Max Back-End
Conventional	28%	36% (up to 45% with strong credit)
FHA	31%	43% (up to 50% with compensating factors)
VA / USDA	No limit	41% (flexible with residual income)

Example: $7,500/month gross income, $1,800 mortgage + $350 in other housing costs, $700 in other debts. Front-end DTI = $2,150 ÷ $7,500 = 28.7% (slightly over conventional limit). Back-end DTI = ($2,150 + $700) ÷ $7,500 = 38% (over 36%, under 43%). Result: FHA approved, conventional borderline.

💡 Expert Pro-Tip

Pay Off a Car Loan, Not Credit Card Minimums, Before Applying: Most people assume eliminating credit card debt is the fastest path to DTI reduction — but paying off a $400/month car loan drops your DTI more per dollar than paying down a credit card balance (which only reduces the minimum payment by ~$10 per $300 paid). If you have 6–12 months before applying for a mortgage, identify your highest minimum-payment debt and eliminate it entirely. A paid-off car loan can swing your back-end DTI by 5–6 percentage points, which could move you from FHA territory into conventional approval.

DTI Ratio FAQ

What is a good DTI ratio for a mortgage?

Below 36% back-end DTI is considered "good" by most conventional lenders. Below 28% is excellent. A back-end DTI between 36–43% may still qualify for FHA loans. Above 43% significantly limits your options and may require a co-borrower, larger down payment, or debt paydown before applying.

Does gross or net income count for DTI?

Lenders use gross income (before taxes) for DTI calculations — not take-home pay. This works in your favor since gross income is higher. If you're self-employed, lenders typically use a 2-year average from your Schedule C net profit, which can be significantly lower than revenue. Self-employed borrowers often face stricter DTI scrutiny.

What debts are NOT counted in DTI?

Utilities, phone bills, groceries, subscriptions, insurance premiums (health, life, auto), and childcare are not counted. Only debts that appear on your credit report with required monthly payments count: mortgage, car loans, student loans, credit card minimums, personal loans, and alimony/child support.

Can I get a mortgage with a 50% DTI?

It's difficult but possible. FHA loans allow back-end DTI up to 50% with "compensating factors" — strong credit score (720+), large cash reserves (3+ months payments in savings), or significant down payment (10%+). Conventional loans with 45%+ DTI require excellent credit (740+) and reserves. Above 50%, most standard mortgage programs won't qualify you.

How quickly can I lower my DTI?

Fastest methods: (1) Pay off a car loan or personal loan entirely — this removes the full monthly payment from your DTI. (2) Add a co-borrower's income — this increases your denominator immediately. (3) Get a raise or part-time income — lenders can count side income with a 2-year history. (4) Pay down credit cards to $0 — minimum payment goes to $25, saving you the full minimum. Each strategy can move DTI by 2–6% within 3–6 months.
