What Is a Good Debt-to-Income Ratio?.

A good debt-to-income ratio is 36% or below. That is the share of gross monthly income going to required debt payments that a lender reads as room for one more payment, and above it the questions start.

DTI is the lender’s own arithmetic, done on the lender’s own terms. It appears nowhere on a credit report, no scoring model can see it, and it exists only inside an underwriting file. For mortgages, the Ability-to-Repay rule in Regulation Z, 12 CFR § 1026.43, put it there by requiring a lender to verify that a borrower can repay before it lends.

We cannot tell you what any lender will approve. Lenders weigh DTI alongside credit history, assets, employment and the loan program, and these bands are guidelines rather than rules.

Lenders read 36% as the line between comfortable and tight

At 36% or below a file reads as comfortable on affordability. From 37% to 43% it stays workable with a closer read of the credit score, from 44% to 49% it needs compensating factors, and at 50% or above a conventional approval becomes unlikely. The bands are lender convention, and the one that carries the decision is the back-end ratio, which counts every required monthly payment.

The bands describe intent, and the loans that actually close sit above the comfortable one. The median debt-to-income ratio at origination for owner-occupied purchase loans was 41% as of January 2026, up from 39% in December 2021 (Urban Institute, 2026). That median sits five points above the 36% a lender reads as room to spare. A guideline marks where a file stops raising questions, not where lending stops. The CFPB’s mortgage resources set out how the ratio is weighed against the rest of an application.

The 28/36 rule splits housing from every other debt

The 28/36 rule is the older of the two thresholds and the one lenders still quote. It asks for housing costs at or below 28% of gross monthly income and total debt at or below 36%. Front-end DTI counts the housing payment alone. Back-end DTI counts housing plus every other required payment, and mortgage underwriting leans on the back-end number.

The two ratios can disagree about the same borrower. A modest mortgage payment carried alongside a financed truck and two student loans clears 28% on housing and fails at the back end, and the back end is the number that decides. Some programs apply a separate front-end limit on top, so a borrower can owe both.

Divide monthly debt by gross income, then multiply by 100

Gross monthly income is the figure before any tax or withholding, which is why a DTI can look healthier than the household budget feels. A borrower with $2,000 in required monthly payments and $6,000 in gross income carries a DTI of 33%. Running the same arithmetic on take-home pay inflates the ratio and reads worse than any lender will calculate it.

1. Add up every required monthly debt payment, including the proposed new loan.
2. Find gross monthly income, the amount before taxes or withholding.
3. Divide total monthly debt by gross monthly income.
4. Multiply by 100 to read the result as a percentage.

DTI skips utilities and counts a $9,000 card as $250

DTI counts required, verifiable, recurring obligations, so the grocery bill, the utility bill and the streaming subscriptions stay out of it. Credit cards enter at the minimum payment. That is why a $9,000 card balance with a $250 minimum weighs less on the ratio than a $480 car payment does, even though the card balance is far larger.

• Counted: the proposed mortgage payment, auto loans, student loans, personal loans.
• Counted: minimum credit card payments, child support, alimony, and any loan you co-signed.
• Not counted: utilities, groceries, insurance outside the housing payment, streaming services.
• Not counted: taxes other than the property tax on the home being financed.

An auto loan enters the ratio at its full monthly payment, and that payment has been climbing. The average monthly payment on a new vehicle reached $770 in the first quarter of 2026, up from $748 a year earlier, while the average used-vehicle payment grew to $531 (Experian, 2026). One financed truck can move a back-end ratio several points on its own.

A card minimum is small against the balance behind it, and that cuts both ways. About 15% of general purpose cardholders made only the minimum payment in 2024, the highest share since at least 2015 (CFPB, 2025). Those balances barely register in DTI while sitting at the top of the utilization ratio a scoring model reads.

DTI passed credit history as the top mortgage denial reason

Debt-to-income became the single largest stated reason for a mortgage denial, rising from 29% of denials in 2018 to 35% in 2024, while credit history held steady at 29%, across more than 30 million home purchase applications (St. Louis Fed, 2026). The ratio now turns away more applicants than the credit report does.

The mechanism is arithmetic. A higher rate raises the monthly payment on the same house, the payment is what the ratio counts, and incomes did not rise to meet it. Nothing about the borrower changed; the denominator stayed put while the numerator climbed.

That failure looks nothing like a thin file or a late payment. A borrower can hold a clean report and a 750 score and still be turned down because the payment does not fit the income.

Why a 36% DTI matters more to a lender than savings

A lender is repaid every month, so the question behind the 36% line is whether one more payment fits into what is left, and a savings balance answers that only once. US households already commit 11.16% of disposable personal income to required debt payments, split between 5.88% on mortgages and 5.29% on consumer debt (Federal Reserve, 2026), a national figure computed on disposable income rather than on the gross income an underwriter divides by.

Reserves still matter. They are a compensating factor rather than a substitute, which is why an applicant with strong savings, a strong score and 49% DTI can be declined while a thinner file at 33% is approved.

Equifax, Experian and TransUnion never see your income

No scoring model can read your income, because income never reaches a report held by Equifax, Experian or TransUnion, and DTI therefore cannot move a score by itself. The five factors that drive a score are payment history, amounts owed, length of history, new credit and credit mix, and none of them is income.

The two still move together in practice. A borrower carrying heavy debt usually shows both a high DTI and high reported balances, and those balances lower the score through utilization while the income figure stays invisible to the model.

Credit utilization measures limits while DTI measures income

Credit utilization compares revolving balances to credit limits and is reported to Equifax, Experian and TransUnion every cycle. DTI compares monthly payments to gross income and lives only in a lender’s file. A borrower can run 4% utilization and 48% DTI in the same month, or the reverse.

One of the two is fixable in a week and one is not. Utilization responds to a payment before the statement closes; DTI responds only when a required payment disappears or the income a lender can verify goes up.

Your mortgage score and your DTI are judged separately

A mortgage application clears two separate tests, and clearing one hard does not carry the other. Fannie Mae’s Desktop Underwriter moved off a hard 620 minimum to a broader credit-risk assessment in November 2025 (Fannie Mae, 2025), while FHA loans still ask for 580 with 3.5% down. Neither of those changes touches the ratio.

Which number a lender pulls is its own question, and the mortgage market does not use the score consumers see in an app, as our guide to the mortgage credit score sets out.

The report underneath that score is also the part most likely to describe the wrong person. In our own read of the database, 66.9% of the 3,482,718 complaints recorded in the CFPB’s public Consumer Complaint Database between July 2025 and June 2026 about incorrect information on a credit report said the information belongs to someone else. These are unverified consumer allegations, and a count tracks how much business a company does as well as how it behaves.

Retiring a small payment cuts DTI faster than a paydown

DTI counts payments, so removing one payment entirely moves the ratio further than shrinking a much larger balance that keeps its payment. Clearing a $220 store card closes a line in the numerator. Paying $8,000 off a 60-month auto loan leaves the $480 payment exactly where it was.

1. Pay off a small loan or card outright to remove its payment from the ratio.
2. Open no new debt in the months before applying for a major loan.
3. Raise verifiable income through a raise, a bonus, or documented side income.
4. Refinance or consolidate to reduce a large required monthly payment.

Consolidation is the one with side effects, and what it does to a score is a separate question from what it does to the ratio, covered in our guide to debt settlement versus consolidation.

Paying balances down does something different to a score than it does to a ratio, and the two can move in opposite directions in the same month. New System, 1 star, June 21, 2026, on Credit Karma: “Paid off $5000 to get a 70 point drop. I paid off $5000 of debt. My credit cards went from fair usage to good usage and they dropped me 70 points with the recommendation to sign up for more cards. What a scam.” A payoff can shift the mix and the balances a scoring model reads, and a drop after one has more than one possible cause. The DTI side was never in doubt: the payment left the numerator the day the account closed, and that change was invisible in the app he was watching.

Fannie Mae, FHA and auto lenders draw different DTI lines

Each loan type sets its own comfort zone, and individual lenders add overlays on top of it. What follows is lender convention rather than a published limit, the same way the bands above are. Conventional approvals cluster at or below 43%, government-backed programs stretch higher where reserves or residual income are strong, and auto and personal lenders commonly work to a total ratio around 45% to 50%.

• Conventional mortgages: many approvals land at or below 43%, and Fannie Mae’s Desktop Underwriter can go above it on a strong file.
• Government-backed mortgages, FHA, VA and USDA: more room, granted on compensating factors such as reserves, residual income, or a long job history.
• Auto loans: lenders commonly look for a total DTI around 45% to 50%, counting the new car payment.
• Personal loans: limits vary widely by lender, with many landing somewhere between 40% and 50%.

The 43% figure has a history worth knowing, because it is still quoted as though it had the force of law. It was written into the General Qualified Mortgage definition under Regulation Z as a hard ceiling, then replaced with a price-based test that compares the loan’s rate to the average prime offer rate. 43% survives as a lender guideline, and it is no longer the regulatory line.

Underwriters verify your income against 2 years of tax returns

Your own estimate starts the conversation and the lender’s verified figures end it. Underwriting pulls a credit report to confirm every monthly payment, then reads pay stubs, W-2 forms and often two years of full tax returns to confirm gross income. A signed Form 4506-C lets the lender pull your return transcript straight from the Internal Revenue Service, so the income on the application is checked against the income you filed.

Self-employed borrowers face the closer look. Lenders often average income across two tax years and subtract certain business deductions, so a strong recent year gets pulled down by a weaker prior one, and the income a lender will count lands below the deposits.

Because verification runs on documents, irregular or undocumented income may not count at all. This is also the difference between the two things lenders hand out early, which our guide to preapproval versus prequalification sets out: one runs the verification, the other takes your word for the numbers.

Co-signing adds the whole monthly payment to your back-end ratio

A co-signed loan is your obligation in underwriting, whatever the payment history says about who actually pays it. Co-sign for your daughter and her whole monthly payment lands in your back-end ratio, and it stays there every month she pays it on time.

Fannie Mae’s Selling Guide lets a lender leave that debt out on one condition, and it is a documentary one: the most recent 12 months of canceled checks or bank statements from the other party’s own account, showing a 12-month history with no delinquent payments (Fannie Mae Selling Guide B3-6-05, 2026). Short of those statements the payment stays in your ratio.

Other moves land in the numerator just as quietly: financing furniture for the new house, opening a card, taking a new car loan, or signing a personal loan between the preapproval and the closing.

The safe approach before a major application is to add no new required payment of any kind. A single modest obligation can carry a borderline ratio across the line a lender draws between approval and denial.

Paying a loan off early cuts DTI and your reserves

Retiring a $220 store card removes its payment from the ratio, and draining $9,000 of savings to clear a car loan removes the reserves an underwriter counts as a compensating factor. The trade is worth making on a small balance with a large payment. It rarely pays on a large balance whose monthly payment survives the paydown.

Timing matters as much as the target. The payment leaves the ratio the day the account closes, while Equifax, Experian and TransUnion show the closed account only on their next reporting cycle, and a paid-off installment loan can move a score by changing the credit mix, which our guide to a score drop after paying off a loan explains. Act a few months ahead of a major application rather than the week before.

36% is the number on your application you can change fastest

Credit history takes months to rewrite. A ratio changes the day a required payment disappears, and that is the practical difference between the two reasons lenders write most often on a denial.

So compute it before a lender computes it for you. Add the payments a lender will see, divide by the income a lender will verify, and if the answer sits above 36%, you know which of the two numbers on your application is worth working on first.

Who helps you challenge an account that should not be on your report

Start your DTI check with the monthly payments you actually owe. If the report lists a debt that is not yours, you have a separate error to dispute. Our September 18, 2026 data shows that paying CreditRefresh members averaged 30 negative entries across the bureaus. These are entries, not 30 distinct debts. Compare the tools on who helps you check and challenge the wrong ones.

A free app can help you watch a reported balance. If you need to dispute an entry at Equifax or Experian, compare the bureau reach as well as the price.

Check the debts on your report before a lender counts them with CreditRefresh

Working out your monthly debt payments is harder when a paid loan still shows a balance or the report lists someone else’s account. CreditRefresh helps you check all three reports and drafts a letter for each entry you choose to dispute. You get the report and the letter in front of you, ready to compare with your own records.

The later report shows whether the entry is still there. In our September 18, 2026 member data, 47.9% of disputed items with a recorded outcome no longer appeared on a later report from the same bureau. Across all dispute types, outcomes were recorded for 2.3% of items in mailed rounds. Use those reports alongside your own payment records when you work out how much debt you pay each month.

Badtank, 5 stars, July 28, 2026: “They showed me debt I didn’t even know about and helped me fix it every step of the way.” Becca, 5 stars, July 25, 2026: “it instantly pulled up my reports and flagged the things that were bringing down my credit score so that I could review and address those problem areas…”

CreditRefresh comes with Refresh Monitoring for $49.99 a month, with no setup fee, no charge per dispute and no contract. You can cancel any time. You choose the entries and read and sign each letter before it is sent.

Frequently asked questions about debt-to-income ratio

Is 20% a good debt-to-income ratio?

Yes. 20% sits below every threshold lenders use, front-end and back-end, and leaves room for a new payment on top of it. At that level the binding question on an application becomes the credit report, the down payment and the reserves rather than the ratio.

Is 50% DTI too high for a mortgage?

For a conventional loan, usually. At 50% and above a conventional approval becomes unlikely, and files that do clear carry compensating factors such as large reserves or a long job history. Programs backed by the Federal Housing Administration and the Department of Veterans Affairs have more room than conventional ones.

Can I get a mortgage with a high DTI?

It happens, on the strength of the rest of the file. Underwriting weighs reserves, residual income, a larger down payment and job stability against the ratio, so a high DTI narrows which programs are open rather than closing the door.

How fast does a lower DTI show up?

Immediately. The ratio is recomputed from whatever payments are in your file at the moment a lender pulls it, so an account closed today is out of the numerator today. A credit score responds on the bureaus’ reporting cycle instead, which can take a full statement period.

Does rent count in a DTI calculation?

Generally not, once a new mortgage payment is set to replace it, because the proposed housing payment takes its place in the ratio. For a loan that does not replace your housing, a lender may count the rent as a recurring monthly obligation.

Can a high income offset a high DTI?

Higher income raises the denominator, which lowers the ratio for the same debt, so income helps directly. A borrower with a high income and equally high payments still presents the same ratio, and the ratio is what the limit is written against.

Does checking DTI require pulling credit?

No. You can compute it from your known monthly payments and your gross income with no credit pull at all. Lenders verify the figure against the credit report and your income documents during underwriting, but your own estimate beforehand carries no score effect.

Does student loan debt count toward DTI during deferment?

Often yes. Many lenders count a student loan payment even when the loan is deferred or in an income-driven plan, using either the documented payment or a set percentage of the balance as an assumed one. The treatment varies by program, so ask the lender how your balances will be counted.
