USDA Rural Development Zero Down Calculator
USDA loans are one of only two mortgage programs in the country that offer true 100% financing — zero down payment. But qualifying depends on more than just where the home is located: your household income has to fall under your county's limit, and your monthly debt has to fit within USDA's ratios. This calculator runs your full payment, including the guarantee fee, and checks both your income eligibility and your debt ratios in one place.

The Two Numbers That Actually Decide USDA Eligibility
Unlike FHA or conventional loans, USDA eligibility isn't primarily about your credit score or down payment — it's about two things most other loan programs don't check at all:
- Where the home is located. The property has to sit inside a USDA-designated rural or eligible suburban area. Despite the name, this covers roughly 97% of the country's land area, including plenty of communities just outside major metro boundaries that most people wouldn't think of as "rural."
- Your household income. USDA loans are designed for low-to-moderate income buyers, so your total household income — everyone living in the home, not just the borrowers on the loan — cannot exceed 115% of the area median income for your county. In most counties, that works out to $122,800 for a household of 1–4 people, or $162,100 for 5–8 people, though the exact number varies by location.
Both of these have to check out before anything else about your file even matters. We verify both for every USDA buyer before you write an offer — not after.
USDA vs. FHA — Why USDA Usually Wins on Cost
For eligible buyers, USDA is almost always the cheaper zero-money-down option compared to FHA. USDA's upfront guarantee fee is 1% versus FHA's 1.75%, and the annual fee is 0.35% versus FHA's 0.55% on most 30-year loans. On top of that, FHA requires a minimum 3.5% down payment while USDA requires none. The tradeoff is eligibility — USDA is restricted by location and income in a way FHA is not. If you qualify for both, USDA is usually worth running the numbers on first.
Debt-to-Income Ratios — The 29/41 Guideline
USDA's standard guideline caps your housing payment at 29% of gross monthly income (front-end ratio) and your total monthly debt — housing plus everything else — at 41% (back-end ratio). Compensating factors like a credit score above 680, three or more months of documented cash reserves, or minimal increase between your current housing payment and your new one can allow a lender to approve a file above these guidelines. The calculator above shows you both ratios in real time so you know where you stand before you apply.
USDA Loans Don't Have a Maximum Loan Amount
Unlike FHA and conventional loans, USDA guaranteed loans don't set a hard maximum loan limit. Instead, how much you can borrow is determined entirely by your income eligibility and your ability to repay under the 29/41 ratios. In practice, this means your income limit and your debt ratios — not a fixed dollar cap — are what actually determine your USDA purchasing power.
Frequently Asked Questions
Do I really need to put $0 down for a USDA loan?
You're not required to put anything down — USDA offers 100% financing, one of only two government-backed programs (alongside VA loans) that allow this. You're welcome to put money down if you choose to, which would lower your loan amount and monthly payment, but it isn't required to qualify.
Does USDA require mortgage insurance like FHA does?
Not exactly — USDA doesn't charge traditional mortgage insurance, but it does charge a guarantee fee that works similarly: a 1% upfront fee (usually financed into the loan) plus a 0.35% annual fee paid monthly for the life of the loan. Both are lower than FHA's equivalent charges, which is a big part of why USDA is often the cheaper option for buyers who qualify for both.
What credit score do I need for a USDA loan?
USDA itself doesn't set a hard minimum, but most lenders look for a credit score of at least 640, since that's the threshold for streamlined processing through USDA's automated underwriting system. Some lenders can work with scores in the 580–620 range with additional documentation and compensating factors — it's worth discussing your specific situation with us directly.
How do I know if a property is USDA eligible?
Eligibility is based on USDA's official rural area maps, which cover a surprisingly large portion of the country — roughly 97% of U.S. land area, including many communities just outside major city boundaries that don't feel "rural" at all. We check the specific address for you before you make an offer, so you know for certain rather than guessing based on how the area looks or feels.
What if my income is slightly over the USDA limit?
Certain deductions are allowed before your income is measured against the limit — including deductions for dependents, childcare expenses, and certain medical costs for elderly household members. Some buyers who look over the limit on paper turn out to qualify once these adjustments are applied. It's always worth having us run your actual numbers rather than assuming you don't qualify based on gross income alone.
