Your FHA loan amount depends on your debt-to-income ratio, credit score, down payment, and the maximum loan limit in your county

The Federal Housing Administration does not set a single borrowing limit for everyone. Instead, lenders calculate how much you can borrow by looking at your monthly debts against your monthly income, your credit history, and how much you can put down. Most lenders will let you borrow up to 96.5% of a home's purchase price with an FHA loan, meaning you need only 3.5% down. But the actual dollar amount you may have access to for depends on what your income and debts allow.

There is also a ceiling: your county has a maximum FHA loan limit set by the federal government. In lower-cost areas, this might be around $440,000. In expensive markets like San Francisco or New York City, it can exceed $1 million. Your lender will calculate what you can borrow based on your finances, then check it against your county's cap. Whichever is lower is what you can actually borrow.

Key Takeaways

  • Lenders use your debt-to-income ratio—your monthly debts divided by your gross monthly income—to set your maximum loan amount, typically allowing up to 43% to 50% depending on your credit score and down payment.
  • Your county has a maximum FHA loan limit that varies widely; you can find your specific county limit on the HUD website before you start shopping.
  • A 3.5% down payment is the minimum for most FHA loans, but putting down more money increases your borrowing power and lowers your monthly payment.
  • Your credit score, savings, employment history, and existing debts all factor into the final number a lender will offer you.
  • Getting pre-may have access to by a lender gives you a real number to work with; online calculators are a starting point but not a final answer.

How lenders calculate your maximum loan amount

Lenders use a formula called the debt-to-income ratio (DTI). They add up all your monthly debt payments—car loans, credit cards, student loans, child support, and the new mortgage payment—and divide by your gross monthly income (before taxes). Most FHA lenders will approve you if your DTI is 43% or lower. Some will go to 50% if you have a strong credit score, substantial savings, or a larger down payment.

Here is how it works in practice: if you earn $5,000 per month gross, a 43% DTI means your total monthly debts (including the new mortgage) cannot exceed $2,150. If you already owe $400 on a car and $200 on credit cards, that leaves $1,550 for your mortgage payment. A lender then works backward from that payment to find the loan amount you can carry.

The calculation also factors in property taxes, homeowners insurance, and mortgage insurance (which FHA loans require). These costs vary by location and loan size, so the same income in different states can support different loan amounts. Your lender will run these numbers for your specific situation.

County loan limits and where to find yours

The Department of Housing and Urban Development (HUD) sets a maximum FHA loan limit for each county every year. These limits are based on local home prices. In rural or lower-cost areas, the limit might be $472,030. In high-cost counties, it can be $1,089,300 or higher. If you want to borrow more than your county's limit, you cannot use an FHA loan.

You can find your county's current limit on the HUD website under "FHA Mortgage Limits." Search by state and county, and you will see the maximum loan amount. This is a hard ceiling—no lender can exceed it, even if your income would support a larger loan. If you are shopping in an expensive area and the county limit is lower than what you need to borrow, you may need to look at conventional loans or put down a larger down payment.

How your credit score affects borrowing power

FHA loans are available to borrowers with credit scores as low as 580, but your score directly affects how much you can borrow. A score of 580 to 619 typically qualifies you for a 43% DTI maximum. A score of 620 or higher often allows lenders to stretch to 50% DTI, meaning you can borrow more on the same income.

A higher credit score also affects your interest rate. A lower rate means a smaller monthly payment, which frees up room in your DTI for a larger loan. The difference between a 6% rate and a 7% rate on a $300,000 loan is roughly $150 per month—enough to change what you can afford. If your score is below 620, improving it before you apply can increase your borrowing power noticeably.

The role of your down payment

The minimum FHA down payment is 3.5% of the purchase price. If you put down more—say 10% or 15%—your loan amount shrinks, which improves your DTI and can lower your interest rate. A larger down payment also reduces the lender's risk, which sometimes allows them to approve you at a higher DTI threshold.

Down payment money must come from your own savings, a gift from a family member, or a grant program. You cannot borrow it. If you have been saving aggressively or received an inheritance, putting down more than 3.5% is one of the clearest ways to increase your borrowing power without waiting to improve your credit or income.

Employment history and income documentation

Lenders verify your income by requesting recent pay stubs, W-2 forms, and sometimes tax returns. If you are self-employed, you will need two years of tax returns and possibly a profit-and-loss statement. If you changed jobs recently, lenders want to see a letter from your new employer confirming your salary and that you are permanent staff, not temporary.

Income that is less than two years old may not count, or may count at a reduced amount. Bonus income, commission, or overtime typically requires two years of history to be included in your may have access to income. If you recently received a raise or started a higher-paying job, you may not be able to use that income yet. This is why some borrowers wait a few months after a job change before applying for a mortgage.

What pre-qualification tells you versus what it does not

A pre-qualification is a quick estimate based on information you provide over the phone or online. It gives you a ballpark number to start house hunting. A pre-approval is more thorough: the lender verifies your income, credit, employment, and assets. A pre-approval letter shows sellers you are serious and gives you a real number to work with.

Neither pre-qualification nor pre-approval locks in your final loan amount. The actual underwriting process—which happens after you make an offer on a home—can reveal issues that lower your approved amount. A lender might discover unreported debts, a recent late payment, or a gap in employment that changes the calculation. This is why it is important to be honest about your financial situation from the start and to avoid taking on new debt or changing jobs between pre-approval and closing.

Frequently Asked Questions

Can I borrow more if I add a co-borrower?

Yes. A co-borrower's income is added to yours, which increases your total may have access to income and your DTI ceiling. However, the lender also adds any debts the co-borrower carries. If the co-borrower has significant debt or a lower credit score, the benefit may be smaller than expected. Both borrowers must be on the loan and the deed.

What if my debt-to-income ratio is too high?

You have a few options: pay down existing debts to lower your monthly obligations, increase your income (though this usually requires documentation of two years of history), put down a larger down payment to reduce the loan amount, or wait and improve your credit score to access a higher DTI threshold. Some lenders also allow compensating factors—such as substantial savings or a very low credit utilization rate—to approve a higher DTI in borderline cases.

Does the FHA loan limit change every year?

Yes. HUD updates county loan limits annually, usually in early fall, based on changes in local home prices. If you are planning to buy next year, check the current limit for your county, but know it may be slightly different when you actually apply. Your lender will use the limit in effect at the time of your application.

Can I get an FHA loan if I have recent late payments?

FHA loans are more forgiving than conventional loans, but recent late payments still matter. A late payment from the last 12 months will likely disqualify you or significantly reduce your borrowing power. Payments that are two or more years old have less impact. If you have recent late payments, waiting a few months or a year before applying will improve your options.

What happens if I find a home that costs more than my pre-approval amount?

You would need to put down a larger down payment to bring the loan amount within your pre-approval, or you would need to be re-evaluated by the lender. If your financial situation has improved—you paid off debt or received a raise—a new pre-approval might be higher. Otherwise, you would need to look at less expensive homes or wait until your income or credit improves.
