Debt-to-income is the ratio that decides how much house you qualify for. See your front-end and back-end DTI, how it compares to Conventional, FHA, VA, USDA and jumbo guidelines, and the most you can put toward housing.
Same income and debts, different rulebooks. Deferred student loans are re-calculated with each program’s rule.
| Program | Your front / back | Standard limit | Max with approval | Result |
|---|
Lenders measure what you can qualify for. These are the targets we suggest so a new payment does not squeeze the rest of your life.
Lenders can approve total DTI of 43% to 50% or more with automated approval.
In Dollars & Sense, we suggest keeping total DTI at 35% or less. Lower debt strengthens your approval and gives you more room.
Lenders count every minimum payment on your credit report.
In Dollars & Sense, we suggest the Debt Snowball: pay off the smallest balance first. Keep card balances under 10% of the limit and pay them in full each month.
DTI is calculated on gross income, before taxes and deductions.
In Dollars & Sense, we suggest keeping your core costs (housing, utilities, food and transportation) below 35% of take-home pay.
These are educational targets from the Dollars & Sense Money Rules, Pat Collins’ financial education program. They are not lending requirements and not individual financial advice. Your loan approval is based on the program guidelines shown on this page. Learn about Dollars & Sense →
Lenders divide your monthly obligations by your gross monthly income. The front-end ratio counts only the new housing payment. The back-end ratio adds every recurring debt on your credit report, and it is the number underwriters care about most.
New housing payment ÷ gross monthly income.
FHA looks for 31% or less, USDA 29%. Conventional, VA and most jumbo loans focus on the back-end ratio.
Housing payment plus all monthly debts ÷ gross monthly income.
This is the “DTI” you hear about. 36% is comfortable, 43% is a common line, and automated approvals can stretch to 50% or more.
| Program | Front-end | Back-end | Deferred student loans | Notes |
|---|---|---|---|---|
| Conventional | No set limit (28% is a common benchmark) | Up to 45% routinely with automated approval (DU/LPA), up to 50% with strong files. Manual underwriting: 36%, up to 45% | 1% of balance (Fannie Mae) or 0.5% (Freddie Mac) | Credit score and reserves drive approvals above 45% |
| FHA | 31% | 43% standard, about 46.9% / 56.9% with AUS approval | 0.5% of balance | Compensating factors include reserves and minimal payment shock |
| VA | None | 41% guideline | 5% of balance ÷ 12 | Above 41%, residual income must exceed VA’s requirement by 20% |
| USDA | 29% | 41%, up to 32% / 44% with GUS approval | 0.5% of balance | Household income limits apply |
| Jumbo | Lender-specific | Usually 43%, some to 45% to 50% | Lender-specific (1% shown) | Larger reserves and higher credit scores required |

Under 36% back-end is considered strong for every loan program. Between 36% and 43% is common and approvable with decent credit. Above 43% you can still qualify, especially with FHA or with conventional automated approval, but the lender will look harder at your credit score, savings and job history.
Gross income, meaning before taxes, health insurance and retirement contributions. That is why a DTI that looks fine on paper can still feel tight in real life. Check the payment against your take-home pay too.
No. Your current rent is replaced by the new housing payment, so leave it out. If you are keeping a home you own, its mortgage payment counts unless it is offset by documented rental income.
They use the minimum monthly payment on your credit report, not the balance. If a card shows a balance with no payment, lenders typically use 5% of the balance unless you can document a lower required payment. Paying a card to zero removes it from DTI.
Lenders still count them. Enter the balance in the deferred student loan field and this calculator applies each program’s rule: 0.5% of the balance for FHA and USDA, 1% for conventional (Fannie Mae), and 5% ÷ 12 for VA. An income-driven payment documented on your credit report can be used instead.
