The FHA loan calculator above gives you a realistic, complete picture of what a Federal Housing Administration loan actually costs each month β not just principal and interest, but the mortgage insurance premium (MIP) that comes bundled with every FHA loan. Most generic mortgage calculators skip this part entirely, which leaves first-time buyers with a payment estimate that's quietly wrong by $100β$300 a month.
Arb Digital built this tool because we spend a lot of time helping lenders, real estate teams, and local service businesses build content people actually trust, and nothing erodes trust faster than a calculator that hides half the real cost. Plug in your numbers below and you'll see exactly where every dollar of your FHA payment comes from.
What This FHA Loan Calculator Does
FHA loans, backed by the Federal Housing Administration, are designed to make homeownership reachable for buyers who don't have a large down payment saved or who have a shorter or bumpier credit history than conventional lenders typically require. The tradeoff is mortgage insurance β FHA charges both an upfront premium at closing and an ongoing annual premium billed monthly for most or all of the life of the loan. This calculator combines all of it: your base loan amount after down payment, the upfront MIP financed into that balance, the recalculated principal and interest on the new total, and the monthly MIP charge, so the number in the "big" box is the number you'll actually see on your mortgage statement.
It's built for people comparing FHA against conventional financing, buyers trying to figure out whether 3.5% down is realistic for their budget, and anyone who wants to sanity-check a loan estimate a lender just handed them.
How to Use the FHA Loan Calculator
- Enter the home price. Use the purchase price on your offer or contract, or a realistic target price if you're still shopping.
- Choose your down payment percentage. FHA's minimum is 3.5% for borrowers with a credit score of 580 or higher; borrowers between 500β579 typically need 10% down. Select the option closest to your situation.
- Enter your interest rate. Use the rate quoted by your lender, or a current market average as a starting estimate β FHA rates often run slightly below conventional rates but the insurance offsets some of that savings.
- Pick your loan term. Almost all FHA borrowers choose 30 years for the lower payment, but 15-year terms are available and build equity much faster.
- Click Calculate. The tool instantly shows your full monthly payment along with a breakdown of the loan amount, upfront MIP, and monthly MIP, so you understand exactly what makes up that number.
The Formula β How FHA Payments Are Calculated
Start with the base loan amount: home price minus your down payment. FHA then adds an upfront mortgage insurance premium of 1.75% of that base loan amount, and β unlike most other insurance premiums β this amount is financed directly into your loan rather than paid separately at closing (though you can pay it in cash if you prefer). So your true starting loan balance is the base amount plus the 1.75% upfront MIP.
From there, principal and interest are calculated the standard way lenders use for any fixed-rate amortizing loan: M = P Γ [r(1+r)^n] / [(1+r)^n β 1], where P is the total loan balance (including financed MIP), r is your monthly interest rate, and n is the total number of monthly payments over the term. On top of that P&I figure, FHA adds an annual mortgage insurance premium β commonly 0.55% of the loan balance per year for most 30-year loans with less than 5% down as of recent guidelines β divided by 12 and billed as part of your monthly payment. The U.S. Department of Housing and Urban Development publishes the current premium structure and eligibility rules at HUD.gov, and it's worth checking there since MIP rates are adjusted periodically.
Why FHA Mortgage Insurance Matters More Than People Think
Conventional loans with private mortgage insurance (PMI) usually let you cancel that insurance once you reach 20% equity. FHA loans work differently, and this is the part that surprises a lot of first-time buyers. If your down payment was under 10%, FHA's annual MIP typically stays on the loan for its entire life β you can't just request cancellation the way you can with conventional PMI. The only ways off FHA MIP in that scenario are refinancing into a conventional loan once you have enough equity, or paying the loan off entirely. If you put down 10% or more, MIP does drop off automatically after 11 years.
This is exactly why the calculator above matters: two loans that look identical on a term sheet β same price, same rate, same term β can have meaningfully different long-term costs depending on how the mortgage insurance is structured. Run your numbers with a few different down payment percentages using the selector above and watch how both the upfront MIP and the ongoing monthly MIP shift. It's often the clearest way to see why saving an extra few percentage points for a down payment can pay off for years.
FHA vs. Conventional: When FHA Actually Wins
FHA tends to make the most sense for buyers with credit scores in the 580β680 range, buyers with a down payment under 10%, or buyers whose debt-to-income ratio is a bit higher than conventional guidelines prefer. Above roughly a 680β700 credit score with 10%+ down, conventional financing often becomes cheaper once you account for FHA's insurance structure, because PMI on a conventional loan is priced based on credit score and can be lower β and it's cancellable. Run the numbers both ways before committing; a loan officer should be willing to show you a side-by-side comparison, and this calculator gives you an independent way to check their math.
One more nuance: FHA loans have county-specific loan limits that cap how large a loan the program will insure. In most of the country the limit tracks a "floor" figure, while high-cost metro areas allow a much higher "ceiling." If your home price is well above the median for your area, confirm your county's FHA limit before assuming this program applies at all.

If you close an FHA loan today and rates drop later, or you simply want to shed the mortgage insurance without switching to a conventional lender, the FHA Streamline Refinance program is worth knowing about. It's designed specifically for existing FHA borrowers, requires far less documentation than a standard refinance, often skips a new appraisal entirely, and can be a fast way to lower your rate and payment. It won't eliminate MIP on its own β you're still refinancing into another FHA loan β but pairing a streamline refinance with a later conventional refinance, once you've built enough equity, is a common two-step strategy homeowners use to escape mortgage insurance altogether while still taking advantage of FHA's easier qualifying standards up front.
Common Mistakes to Avoid
- Forgetting the upfront MIP changes your loan balance. Buyers often calculate P&I on the home price minus down payment alone, then wonder why their real payment is higher β the financed 1.75% upfront premium adds to the balance you're paying interest on.
- Assuming MIP disappears at 20% equity like conventional PMI. On most FHA loans with under 10% down, it doesn't β you need to refinance or pay off the loan.
- Not shopping the rate. FHA rates can vary meaningfully between lenders even though the insurance rules are federally set. A quarter-point difference in rate matters just as much on an FHA loan as any other.
- Ignoring the county loan limit. FHA won't insure a loan above your county's cap regardless of your qualifications.
- Skipping the 15-year comparison. A shorter term raises the monthly payment but can cut total interest and MIP exposure dramatically β worth running once before you decide.

Frequently Asked Questions
FHA allows credit scores as low as 500, though 3.5% down requires at least a 580. Borrowers with scores between 500 and 579 typically need 10% down, and individual lenders often set their own higher minimums.
If your down payment was under 10%, MIP generally stays for the life of the loan unless you refinance into a conventional mortgage once you have enough equity. If you put down 10% or more, MIP is automatically removed after 11 years.
It's almost always financed into the loan balance, meaning it's added to what you borrow rather than paid separately at closing. Some buyers choose to pay it in cash to keep the loan balance lower, though this is optional.
The upfront premium is typically 1.75% of the base loan amount. The annual premium varies by loan term, loan-to-value ratio, and loan amount, commonly landing around 0.55% per year for standard 30-year loans with less than 5% down β check current rates on HUD.gov since they're periodically updated.
Yes. FHA sets county-by-county loan limits each year, with a lower "floor" limit in most areas and a higher "ceiling" limit in expensive metro markets. Loans above your county's limit aren't eligible for FHA insurance.
It depends on your credit score and down payment. FHA often wins for buyers with lower credit scores or smaller down payments; conventional financing frequently becomes cheaper once you have 10%+ down and a credit score above roughly 680β700, since conventional PMI is cancellable and can be priced lower.
