Quick answer: Your debt-to-income ratio (DTI) is your total monthly debt payments divided by your gross monthly income (your pay before taxes). As of October 2026, a DTI at or under 36% falls in the range most published guidelines treat as lower risk. Conventional loans commonly work up to the mid-40s, and as high as 50% when the lender's approval software gives a strong result. FHA can go higher when your file has strengths that offset the ratio. VA uses 41% as a guide, not a hard cap, and leans on the money you have left each month.
Run your own numbers in the DTI calculator or ask a loan officer to check your DTI.
DTI is the number that decides how much house you can buy. It often matters more than your credit score or the rate. This guide shows what counts as debt, what does not, what a good DTI looks like, the real limits by loan type, and the fastest ways to give yourself more room. If a student loan is the debt in question, the figure that lands in your ratio depends on which rulebook counts your student loan payment.
Capacity is only one of the four things an underwriter (the person who approves the loan) weighs. Your ratio gets read next to your credit history, the cash you have left after closing, and the home itself. That is why two buyers with the same DTI can get different answers. For the whole picture before you apply, here is how lenders qualify you using the four Cs of credit.
Key takeaways
- DTI = monthly debt payments ÷ gross monthly income. Lenders care most about the "back-end" number, which includes your full new house payment.
- What counts: minimum credit card payments, car loans and leases, student loans, personal loans, support you pay, and the new house payment. What does not: utilities, groceries, phone, subscriptions.
- Room by program: conventional to about 50% with a strong automated approval, FHA often higher with strengths that offset the ratio, VA guided by the money left over each month (41% is a guide, not a wall).
- Fastest fix, in most cases: get rid of a whole monthly payment, not part of a balance. Clearing a whole monthly payment usually frees more room than the same cash spread across a card balance.
What is a debt-to-income ratio and how is it calculated?
DTI is your monthly debt as a percentage of your gross monthly income. The Consumer Financial Protection Bureau (CFPB), the federal agency that oversees mortgage lending rules for consumers, puts the purpose plainly:
"This number is one way lenders measure your ability to manage the monthly payments to repay the money you plan to borrow."
Consumer Financial Protection Bureau, "What is a debt-to-income ratio?" (page last reviewed August 28, 2023)
Lenders look at two versions of the number:
- Front-end DTI: just the new house payment divided by income. The house payment is often called PITI: principal, interest, property taxes and homeowners insurance. HOA dues (fees you pay a homeowners association) get added if the home has them.
- Back-end DTI: the house payment plus every other monthly debt payment. This is the number that drives approvals.
| Step | What you add up | Example |
|---|---|---|
| 1 | Gross monthly income (before taxes) | $8,000 |
| 2 | New house payment (PITI plus any HOA dues) | $2,300 |
| 3 | Other monthly debts: car $450, student loans $250, card minimums $150 | $850 |
| 4 | Front-end DTI: step 2 ÷ step 1 | $2,300 ÷ $8,000 = 28.8% |
| 5 | Back-end DTI: (step 2 + step 3) ÷ step 1 | $3,150 ÷ $8,000 = 39.4% |
At 39.4%, this file sits inside the usual published range for the major loan programs. Your real qualifying math is confirmed in underwriting.
How do you calculate your own DTI?
Use this calculator with your own monthly numbers. It works in your browser, saves nothing and sends nothing. Enter gross income, the house payment you are aiming for, and the minimum payments on your other debts.
An estimate for planning only. It is not a loan approval, quote or commitment to lend. Your lender confirms the real numbers.
What is a good debt-to-income ratio for a mortgage?
There is no single magic number. These bands are rules of thumb drawn from the major rulebooks. Fannie Mae is one of the two agencies that set the rules for most conventional loans. It caps manually underwritten loans at 36%. It allows up to 45% when the borrower meets its credit score and savings minimums, and up to 50% when its approval software, Desktop Underwriter (DU), approves the file.
| Back-end DTI | What it usually means |
|---|---|
| 36% or less | Within the range most published guidelines accept without extra review. Approval is never guaranteed. |
| 36% to 43% | Within the range most programs accept. Lenders look a little closer at credit and savings. |
| 43% to 50% | Possible with a strong file. Savings left after closing and steady income carry the weight. |
| Over 50% | Hard for most programs. Lowering a payment or adding income usually comes first. |
A "good" DTI for you also depends on your budget, not just the lender's limit. A ratio a lender will approve can still feel tight if you have costs a lender never counts, like child care or commuting.
What counts as debt, and what doesn't?
| Counts | Doesn't count |
|---|---|
| New house payment (PITI plus HOA) | Utilities, phone, internet |
| Minimum credit card payments | Groceries, gas, living costs |
| Car loans and leases | Insurance not tied to the home |
| Student loans (program-specific calculation) | Subscriptions and memberships |
| Personal loans, other mortgages | Some debts with 10 or fewer payments left, if the payment is small (program rules vary; leases always count) |
| Child support and alimony | 401(k) loans (repaid to yourself) |
Two details buyers often get wrong. First, it is the minimum card payment that counts, not your balance or what you actually pay. Second, the bottom of the fraction is gross income, the number before taxes, which works in your favor.
What DTI limits apply to each loan type in 2026?
| Program | Typical comfort zone | Upper range with a strong file |
|---|---|---|
| Conventional | Up to about 45% | About 50% with a strong DU approval |
| FHA | 31% front-end and 43% back-end on a manual review | Higher with offsetting strengths, such as savings, credit or money left over each month |
| VA | 41% guideline | No hard cap. Residual income is the real test |
| USDA | 29% front-end and 41% back-end | Higher with an automated approval (GUS Accept) or a Rural Development waiver based on offsetting strengths |
Two terms in that table are worth knowing. Compensating factors are strengths that offset a high ratio, like several months of house payments left in savings after closing. Residual income is the money a VA borrower has left each month to cover living costs, after taxes, the house payment (including upkeep and utilities) and other debts. VA sets minimum amounts by family size and region. Valley West Mortgage is not affiliated with or endorsed by HUD, FHA, the VA or USDA.
Valley West takeDTI limits are not cliffs. They are a back-and-forth with the automated underwriter, and the levers are savings, credit score and documented income. The same 47% can get different answers depending on documented income, savings and credit, so the number alone doesn't decide the outcome. If a pre-qualification elsewhere said "your DTI is too high," treat that as the start of the conversation, not the end. We offer conventional, FHA, VA and other programs, and each has its own guidelines, so a file that doesn't fit one program may be reviewed under another. Eligibility is not guaranteed.
What happens if your DTI is too high?
A high DTI does not always mean a no. It usually means one of these:
- A smaller loan. The lender approves you, but for a lower price range that brings the ratio back in line.
- More paperwork. The underwriter asks for proof of savings, extra income, or why a debt will end soon.
- A different program. A file that does not fit one rulebook can fit another. FHA and VA weigh other strengths more heavily than some conventional files do.
- A short wait. Paying off one small loan or waiting for a raise to show on paper can change the answer in a few weeks.
Before you shop, it helps to know your range. Our guide on how much house you can afford walks through price range, and the mortgage calculators show payment math.
How can you lower your DTI fast?
- Pay off payments, not balances: paying off a $450 a month car loan frees about $450 of monthly debt. The same cash put toward a credit card only cuts the minimum payment a little.
- Don't finance anything before closing: a new car or furniture plan during escrow can sink an approval overnight.
- Document all income: overtime, bonuses, a second job with a two-year history, or a co-borrower's income all grow the bottom of the fraction.
- Check the near-payoff rule: debts with 10 or fewer payments left can sometimes be left out if the payment is small. Each program has its own limits, and car leases always count.
- Buy the payment down: a temporary buydown usually does not change your qualifying DTI (conventional and FHA loans qualify you at the full note rate), but permanent points lower the payment that goes into the ratio. See how mortgage rate buydowns work.

Get your fast quoteFrequently asked questions about DTI
What is a debt-to-income ratio?
Your total monthly debt payments divided by your gross monthly income, as a percentage. It measures how much of your income is already spoken for before the mortgage is added.
What DTI do I need to buy a house in 2026?
Conventional loans commonly work to the mid-40s, and up to about 50% with a strong automated approval. FHA can go higher when your file has offsetting strengths. VA uses residual income, with 41% as a guideline rather than a cap. For what those strengths look like in practice, see our guide to FHA loans in Las Vegas.
What is a good debt-to-income ratio?
At or under 36% falls in the range most published guidelines treat as lower risk. Between 36% and 43% is within the range most programs accept. Above 43%, approval usually depends on savings, credit and documented income. No ratio guarantees approval.
Is DTI based on gross or net income?
Gross, which means before taxes. The bigger number on the bottom of the fraction works in your favor.
Do utilities and subscriptions count in DTI?
No. Only credit payments count: card minimums, car loans, student loans, personal loans, support you pay, and the new house payment.
Does a debt with only a few payments left count?
Sometimes not. Debts with 10 or fewer payments left can sometimes be left out if the payment is small. Each program has its own limits, and car leases always count. Your loan officer checks the rule for your loan type.
Does DTI affect my credit score?
No. Credit reports do not list your income, so DTI is not part of your score. Lenders figure it separately when you apply.
What's the fastest way to lower DTI?
Get rid of an entire monthly payment, like paying off a car loan, and avoid financing anything new before closing. Documenting more income helps just as much.
