Formula
Your DTI compares what you owe each month with what you earn before tax. Lenders look at two versions of it.
All monthly debts ÷ gross income × 100The main number lenders quote. It includes housing plus car loans, student loans, card minimums and every other recurring debt.
Housing costs ÷ gross income × 100Also called the housing ratio. It covers only the mortgage or rent payment, property tax, home insurance, HOA dues and mortgage insurance.
$2,200 ÷ $6,000 = 36.7%Earn $6,000 a month with a $1,500 mortgage and $700 of other debts? Your front-end DTI is 25% and your back-end DTI is 36.7%.

Benchmarks
Most lenders group back-end DTI into four bands. The lower your ratio, the easier it is to get approved and the better the rates you are offered.
36% or less
Comfortable for almost every lender. Ideally no more than 28% goes to housing.
37% to 43%
Still approvable for most mortgages, though some lenders will ask for more savings.
44% to 50%
Usually needs automated approval plus strong credit, reserves or a larger down payment.
Over 50%
Most lenders decline at this level. Paying down debt first is usually the fastest fix.
Loan limits
Typical limits used by lenders and automated underwriting systems. Exact approval depends on your full profile, so treat these as guides rather than guarantees.
| Loan type | Front-end | Back-end | Notes |
|---|---|---|---|
| Conventional | 28% | 36%, up to 45% to 50% with automated approval | Strong credit and cash reserves unlock the higher limits. |
| FHA | 31% | 43%, up to about 56.9% with AUS approval | Popular with first-time buyers and lower credit scores. |
| VA | No set limit | 41% guideline | Residual income can offset a higher ratio. |
| USDA | 29% | 41%, up to about 44% with GUS approval | For eligible rural and suburban homes, with income limits. |
| Jumbo | Varies | Often 43% or lower | Stricter because loan amounts are larger. |
| Home loans in India (FOIR) | Not used | About 40% to 60% of net income | Higher earners usually get higher FOIR limits. |

See whether FHA, VA or USDA limits suit you better than a conventional loan when your ratio is on the high side.
A lower DTI signals less risk, which can mean a lower interest rate, smaller fees and a bigger approved loan amount.

Improve it
Small changes to monthly payments move your ratio faster than you might expect.
FAQ
A back-end DTI of 36% or less is considered good by most lenders, ideally with no more than 28% going to housing. Ratios of 37% to 43% are manageable, 44% to 50% are high, and above 50% most lenders will decline.
Add up all your monthly debt payments, divide the total by your gross monthly income and multiply by 100. For example, $2,200 of debts on a $6,000 income gives a DTI of 36.7%.
Front-end DTI includes only housing costs such as the mortgage or rent, property tax, insurance and HOA dues. Back-end DTI includes housing plus every other monthly debt, such as car, student and personal loans and card minimums.
Conventional loans allow 36% with manual underwriting and up to 45% to 50% with automated approval. FHA loans use 43% as a standard limit but can approve up to about 56.9%. VA loans use a 41% guideline, and USDA loans use 41%.
For a mortgage application, lenders replace your current rent with the proposed new mortgage payment. Some personal loan and auto lenders include rent, so enter it if you are checking eligibility for those loans.
Debt to income ratio uses gross income, which is your pay before taxes and deductions. Indian banks often use net take-home pay for FOIR instead, which makes FOIR limits look tighter.
Everyday costs such as utilities, phone bills, groceries, fuel, health insurance, subscriptions and income taxes are not counted. Only debts on your credit report and court-ordered payments are included.
FOIR, or fixed obligations to income ratio, is how Indian banks measure the same idea. It divides all EMIs and fixed obligations by monthly income, usually net income, and most banks cap it between about 40% and 60% depending on salary.
Pay down credit card balances to cut minimum payments, clear small loans that are nearly paid off, add a co-borrower with income, or refinance to lower monthly payments. Avoid taking on new credit before you apply.
