You have only 3.5% saved for a down payment. FHA loans make that possible-but mortgage insurance (MIP) adds a chunk to your monthly cost. How much will you actually pay each month, and is FHA the right move?
What This Calculator Does
An FHA loan calculator estimates your monthly mortgage payment for a Federal Housing Administration loan, including the mortgage insurance premium (MIP) that makes these low down-payment loans possible. You input the home price, your down payment percentage (usually 3.5% for FHA), your interest rate, and loan term, and the calculator computes your base payment, the MIP, property taxes, homeowners insurance, and HOA fees if applicable. It shows your total monthly payment, how much interest you'll pay over the loan, and the total cost of MIP over the loan's life. The calculator also clarifies FHA rules so you understand whether you qualify and what to expect.
How to Use This Calculator
Step 1: Enter the home purchase price. This is the price you're offering or that the appraisal determines. The purchase price drives everything-your loan amount, your down payment, and your insurance cost. If you're shopping and haven't found a home yet, use your target price range.
Step 2: Input your down payment percentage. FHA loans require a minimum 3.5% down for borrowers with a 580+ credit score. If your credit score is 500โ579, FHA requires 10% down. Enter your intended down payment. The calculator will compute the loan amount (purchase price minus down payment).
Step 3: Enter your interest rate. This is your annual percentage rate (APR). FHA rates vary by lender and credit score; typical rates range from 5% to 7% depending on the market and your creditworthiness. Contact a few lenders for rate quotes before running this calculator. If rates are changing rapidly, refresh your quotes.
Step 4: Set your loan term in years. FHA loans typically come in 15-year or 30-year terms. A 30-year loan has smaller monthly payments but costs more in total interest. A 15-year loan has higher monthly payments but you pay less interest overall. Choose what fits your budget.
Step 5: Add property taxes, insurance, and HOA if applicable. Property taxes vary wildly by location. Homeowners insurance typically costs 0.5โ1% of the home value annually. HOA fees are optional but common in some areas. The calculator includes all of these in your total monthly payment estimate.
The calculator outputs your monthly payment, total mortgage insurance premium paid over the loan, and a full payment breakdown.
The Formula Behind the Math
FHA loans use standard mortgage math, plus an additional mortgage insurance premium layer.
Base loan amount:
Loan Amount = Home Price โ Down Payment
Monthly mortgage payment (principal and interest):
Monthly Payment = Loan Amount ร [r(1 + r)^n] / [(1 + r)^n โ 1]
Where r = annual rate / 12, and n = months
Mortgage Insurance Premium (MIP) for loans with <10% down (30-year):
For loans with down payments of 3.5%โ9.99%, FHA charges:
MIP calculation:
Annual MIP = Loan Amount ร 0.0055 / 12 = Monthly MIP
Here's a complete example: You're buying a $300,000 house with 3.5% down at 5.5% APR for 30 years.
Step 1: Calculate down payment and loan amount.
Step 2: Add upfront MIP (rolled into the loan).
Step 3: Calculate monthly payment (principal and interest).
Using the formula with r = 0.055/12 = 0.00458, n = 360:
Monthly P&I โ $1,671
Step 4: Calculate annual MIP on the original loan amount.
Annual MIP: $289,500 ร 0.0055 = $1,593
Monthly MIP: $1,593 / 12 = $133
Step 5: Total monthly payment (before taxes and insurance).
$1,671 (P&I) + $133 (MIP) = $1,804
Step 6: Add property tax, insurance, HOA.
Total MIP over 30 years:
$133/month ร 360 months = $47,880

FHA vs. Conventional Mortgage: The MIP Trade-Off
You found a house for $250,000. You have $10,000 (4% down) saved. With a conventional loan, you'd need 20% down ($50,000) to avoid PMI. With FHA, you can buy now at 3.5% down ($8,750). The FHA loan costs more monthly because of MIP ($100โ$150/month depending on terms), but you don't have to wait years to save an additional $40,000. The MIP is your cost for the privilege of buying sooner. Over 30 years, you'll pay roughly $40,000โ$50,000 in total MIP-substantial but often worth it if homeownership is a priority and the monthly payment is manageable.
FHA MIP Duration: When Does It End?
This is crucial and often misunderstood. For FHA loans with less than 10% down, MIP lasts the entire 30-year loan term (as of current rules). You cannot remove it by refinancing, and it doesn't drop off after a certain percentage of the loan is paid. If you put down 10% or more, MIP can be removed after 11 years. The calculator factors in full-term MIP for down payments under 10%. This is why putting down 10% instead of 3.5% can save tens of thousands-MIP drops off after 11 years instead of never. Run both scenarios and compare.
Strategic Down Payment: 10% vs. 3.5%
You have $20,000 saved for a $300,000 house. Option A: FHA at 3.5% down ($10,500), keeping $9,500 liquid. Option B: FHA at 10% down ($30,000)-but you don't have that yet. Option C: wait, save more, and go conventional. Let's compare A and B assuming you find $30,000 eventually. With 10% down, MIP drops after 11 years (saving you ~$26,000 in years 12โ30). With 3.5% down, you never drop MIP (~$50,000 over 30 years). The extra $9,500 down payment saves roughly $24,000 in MIP-a strong return if you can afford it. However, if you can't save the extra $9,500 without depleting your emergency fund, the 3.5% option is worth the higher long-term cost for financial safety.
MIP on a 15-Year FHA Loan
Shorter terms reduce MIP duration but not the percentage rate. A 15-year FHA loan at 3.5% down still charges 0.55% annual MIP. Your monthly payment is higher (because principal is spread over fewer months), but the loan ends in 15 years, so total MIP paid is lower than a 30-year loan. The monthly payment might be $300โ$400 higher, but you'd save $20,000โ$30,000 in MIP. Whether it's worth it depends on your budget and long-term plans. The calculator helps you compare both scenarios.
Tips and Things to Watch Out For
Mistake #1: Forgetting MIP is permanent for loans with <10% down. Many borrowers assume MIP will drop off once they've paid 20% of the home's value. It won't on an FHA loan unless you put down 10%+ initially. Factor in full-term MIP when deciding whether FHA is right for you.
Mistake #2: Underestimating property tax and insurance. The FHA calculator handles principal, interest, and MIP, but property taxes and insurance vary hugely by location. A $300,000 home in Texas might have $2,500 annual property tax, while the same home in New Jersey costs $7,500+. Never assume taxes without checking your local assessor's website. Insurance also varies-coastal areas pay more due to hurricane risk.
Non-obvious fact: FHA borrowers can receive a gift for their down payment. You don't have to save all 3.5% yourself. Relatives can gift funds (with proper documentation). This opens FHA loans to more people and can reduce the total amount you personally need to save. However, lenders have rules about gift letters and sources-ask your lender about their policy.
Money-saving hack: Put down slightly more than 3.5% to reduce your MIP base. If you have $15,000 saved and are considering a $300,000 house, a 5% down payment ($15,000) still qualifies for FHA, but your MIP is calculated on a smaller loan amount. You're not hitting the 10% threshold, but every percentage point above 3.5% saves a small amount on MIP. Sometimes 5% is the sweet spot between affordability and long-term cost.
Watch out for debt-to-income ratio requirements. FHA loans have more lenient credit requirements than conventional mortgages, but they're strict about debt-to-income (DTI) ratio. Most lenders won't approve you if your total monthly debt payments exceed 43% of your gross income. Student loans, car loans, credit cards-all count. Calculate your DTI before applying; don't assume you're approved just because you have a 3.5% down payment saved.

Frequently Asked Questions
What credit score do I need for an FHA loan?
The minimum is 500, but most lenders require 580+. At 580โ599, you typically need 10% down. At 600+, you can do 3.5% down. Your credit score affects your interest rate too-a 700+ score gets lower rates than a 600 score. Check your credit before applying, and if it's low, you might delay to build it up. Even a 20-point improvement can save thousands in interest over 30 years.
Can I use an FHA loan for a second home or investment property?
No. FHA loans are for primary residences only (the home you'll live in at least 50% of the time). You cannot use FHA for vacation homes, rentals, or investment properties. If you're buying an investment property, you'll need a conventional loan or an investor loan product.
What's the maximum FHA loan amount?
It varies by county, but it's typically in the $400,000โ$800,000 range. Check the Federal Housing Administration website for your specific county. Some high-cost areas have higher limits. If your home price exceeds the limit, you'll need a conventional loan.
Do I have to pay both upfront MIP and annual MIP?
Yes. Upfront MIP (1.75%) is usually rolled into your loan amount, so you pay it over 30 years as part of your mortgage. Annual MIP (0.55% for loans under 10% down) is added to your monthly payment. Both together make FHA loans more expensive monthly than conventional loans, but they enable low down payments. The calculator includes both.
Can I remove FHA MIP by refinancing to a conventional loan?
Yes-if you've built enough equity. Once you have 20% equity (either through paydown or home appreciation), you can refinance to a conventional loan without MIP. However, refinancing has closing costs, so do the math: if you're only 2โ3 years into a 30-year loan, the cost to refinance might not be worth the MIP savings yet. Run the numbers or consult a lender.
Is FHA or conventional better if I have a higher down payment?
If you have 20%+ down, conventional is usually cheaper because there's no PMI or MIP. However, if you have 5โ15% down, FHA might be cheaper because conventional PMI can be higher than FHA MIP for marginal down payments. Always compare actual quotes from both loan types before deciding.
What if my home doesn't appraise for the purchase price?
If the appraisal comes in lower than the purchase price, your loan-to-value ratio increases, which can affect your eligibility and rates. For example, if you're buying at $300,000 but it appraises at $280,000 and you put down 3.5% of the purchase price, your actual LTV is higher. You might need to increase your down payment or renegotiate the price. This is a real risk; don't assume the appraisal will match the offer price.
