USDA Loan Calculator

If you’re thinking about buying a property in a rural part of the United States, my USDA loan calculator could help you determine eligibility.

Aside from estimating your full monthly payment, including the USDA guarantee fee and annual fee, it considers household income eligibility.

This ensures you actually qualify for a USDA loan based on the county in which you’re buying and the number of individuals in your household.

Because a big determinant of eligibility is having an income at or below the county limit.

There’s also a link to the USDA property eligibility map to make sure the home itself is located in an eligible location.

USDA Loan Calculator

Estimate your total monthly USDA loan payment — principal, interest, taxes, insurance, and the USDA guarantee fee — and see whether your household income falls within typical USDA eligibility guidelines.

USDA Guaranteed Loans are almost always 30-year fixed-rate
💡 Unlike FHA or conforming conventional loans, USDA Guaranteed Loans have no set maximum loan amount. How much you can borrow is determined by your income, debts, and repayment ability rather than a fixed dollar cap.

USDA Guarantee Fee

💡 USDA loans don’t use monthly PMI. Instead they charge a one-time upfront guarantee fee (1.00%) and an ongoing annual fee (0.35%) of the loan balance, split into your monthly payment.

💡 Unlike conventional PMI, the 0.35% annual fee doesn’t automatically cancel once you reach 20% equity. It generally continues for the life of the loan — the main way to remove it is refinancing into a conventional loan once you qualify.

Household Income Eligibility

💡 USDA counts the income of everyone 18 or older who will live in the home — not just the borrower(s) on the loan — against the area’s income limit, typically 115% of the area median income. Look up your county’s limit on USDA’s Guaranteed Rural Housing income limit map — limits vary widely by county and household size. On that map, most borrowers should use the row labeled “MOD.INC-GUAR.LOAN” — that’s the moderate-income limit for the standard USDA Guaranteed Loan program most people use.
📍 The property itself must also sit in a USDA-eligible rural area — this is separate from the income limit above. Check any specific address on USDA’s Property Eligibility map. Many suburban areas qualify, not just farmland — it’s worth checking before assuming a property doesn’t count.
This doesn’t calculate your limit — it just tells you which income column to pull from the map

Only fill this in if it applies to you. This only matters if your household has $50,000 or more in cash, savings, checking, and non-retirement investment accounts combined (not counting retirement accounts). If that’s not you, leave this at $0 and ignore it entirely.

Debt-to-Income Snapshot (optional)

💡 This uses your repayment income — typically only the applicant(s) on the loan, which can be less than the total household income used for the eligibility check above. For a full multi-category debt breakdown across loan types, try our DTI Calculator.

Itemized Estimate

Disclaimer: This calculator is for informational and educational purposes only and does not constitute financial, legal, or tax advice. It does not guarantee loan approval, a specific interest rate, or USDA eligibility. The 1% upfront and 0.35% annual guarantee fees reflect the current USDA Guaranteed Loan fee structure as of this writing and are reviewed by USDA each federal fiscal year; the annual fee is calculated here against the original financed loan balance for simplicity, though USDA technically bases it on the average scheduled unpaid balance for the year, which declines slightly as you pay down the loan. The income-eligibility check is only as accurate as the area income limit you enter — this calculator does not look up county-specific limits, so confirm the exact figure for your county and household size on the USDA income limit map linked above, and separately confirm on the USDA property eligibility map (also linked above) that the property itself sits in a USDA-eligible area. The household asset flag is a simple threshold check, not a calculation — USDA’s actual imputed-income formula for assets above $50,000 depends on prevailing passbook savings rates and other underwriting details this calculator doesn’t attempt to reproduce; if it applies to you, ask your lender for the exact impact on your eligibility. The down payment savings comparison uses a generic 3% conventional minimum for illustration only — actual conventional down payment requirements vary by program, lender, credit score, and property type. Front-end and back-end DTI guidelines of roughly 29% and 41% are general USDA benchmarks, not hard cutoffs — actual underwriting can allow higher ratios with strong compensating factors (credit score, cash reserves) or apply overlays that are stricter. Principal & interest is estimated using a standard fixed-rate amortization formula; your actual payment will depend on your lender’s underwriting and your final rate. Consult a USDA-approved lender for your exact numbers.

How to Use the USDA Loan Calculator

First, enter your proposed home purchase price, down payment (USDA loans allow zero down payment), and your mortgage rate and loan term (most commonly 30 years).

Next, select if you want the upfront guarantee fee (1%) to be rolled into the loan or paid out-of-pocket. 

Most USDA home buyers elect to roll it into the loan amount to avoid any additional costs at closing.

There is also a 0.35% annual fee that is a life-of-the-loan cost that is part of your ongoing monthly mortgage payment.

So you pay it along with principal, interest, taxes, and insurance. The good news is it goes down each year as your outstanding loan balance decreases.

Household Income Eligibility on USDA Loans

The next section deals with household income eligibility, which is important because USDA loans are generally reserved for those with low-to-moderate income only.

It’s not a loan program for ultra-wealthy home buyers and the like.

As such, you’ll need to enter how many people will reside in the household (all ages).

For example, if you have a spouse and three kids, you’d enter “5” here.

Then you enter the total household income before taxes from all sources (gross income). This includes things like child support and alimony.

Generally, you’re only entering income derived from those aged 18 and up, though there are rare exceptions for things like a child’s trust fund distributions or their child support/alimony.

Think it all through to ensure you don’t miss anything. And also take the time to look up the Guaranteed Rural Housing income limit map.

Once you know these limits, you’ll know if your income is low enough to qualify based on the income limits.

Find the county the property is located in, the household size, and use the “MOD.INC-GUAR.LOAN” row (most common for the popular standard 502 Guaranteed loan program).

Your income cannot exceed those limits, which are already listed at 115% of the area median income (AMI).

Note that if your income exceeds these limits, there are deductions for things like dependents, childcare expenses, medical expenses, and elderly care. But they might not move the dial much unless it’s a very fringe case.

One little caveat is household liquid assets, not counting retirement accounts. If you have more than $50,000, which is calculated post-closing (so if you use any of it for the loan and it goes below $50,000 it’s not a factor), the USDA loan program will impute the income.

This means they’ll add it to your annual income for qualifying purposes, but it’s likely quite negligible.

For example, if you have $60,000 in a savings account earning 3%, it would add only $1,800 to your total income, though potentially pushing you over the limit.

Don't Forget Your DTI and Credit Scores for Qualifying Purposes

The USDA loan calculator has an optional section related to your debt-to-income ratio (DTI), which is also an important qualifier.

You simply enter your repayment income, which is the income solely from the person(s) applying for the loan, not the entire household.

Then you enter your total monthly liabilities, the ones that show up on a credit report. Things like an auto loan/lease, student loan payments, minimum credit card payments, etc.

For example, a $500 car payment, $300 in minimum credit card payments, and $250 in student loan payments would be $1,050.

This will quickly determine your DTI and the calculator will let you know if you qualify based on maximum DTI limits.

So all in all, the USDA loan calculator covers a lot of important stuff, including income limits, property eligibility (based on the link provided), and DTI limits.

This should give you a good idea as to whether you qualify for a USDA loan, though don’t forget things like minimum credit score (the USDA doesn’t have one but individual banks might!).

As always, speak with a licensed loan officer or mortgage broker to run the real numbers and determine actual eligibility.
