What shifts your rate
    Loan breakdown

      Estimates for education, not a loan offer. Rate adjustments are a simplified model of how lenders price credit, down payment, occupancy and term; your real rate depends on your lender and the market on the day you lock. PMI is estimated for conventional loans under 20% down.

      Year by year

      Where the money actually goes.

      Early payments are mostly interest; the principal share grows over time.

                    FHA vs conventional: which loan actually fits you?

                    Calculate My RateReading time: about 3 min · Loan types

                    FHA vs conventional mortgages compared: down payment, credit scores, mortgage insurance, and loan limits. A clear breakdown sourced from HUD, Fannie Mae, and Freddie Mac.

                    They're the two most common ways to buy a home — but they play by different rules on down payment, credit, and mortgage insurance. Here's the honest side-by-side, so you can pick with your eyes open.

                    Almost every buyer lands on one of two paths: an FHA loan, insured by the government through the Federal Housing Administration, or a conventional loan, which follows the guidelines set by Fannie Mae and Freddie Mac. Neither is "better" — they're built for different situations. The trick is knowing which one your numbers point to.

                    The short version

                     FHA loanConventional loan
                    Minimum down3.5% (580+ score)3% first-time / 5% standard
                    Credit floor500–580Typically 620+
                    Mortgage insuranceMIP — often for the life of the loanPMI — drops off at 20–22% equity
                    Upfront insuranceYes (1.75% upfront MIP)None
                    Best forLower credit, thinner savingsStronger credit, avoiding long-term insurance

                    Down payment

                    FHA's headline number is 3.5% down if your credit score is 580 or higher (and as low as 500 with 10% down). Conventional actually goes lower for many buyers: Fannie Mae's HomeReady® and the Conventional 97 program allow 3% down for a first-time buyer's primary residence, with 5% the standard minimum otherwise.

                    So the old idea that "FHA is the low-down-payment loan" isn't quite true anymore — conventional can start lower. The bigger difference is what happens after you put that money down.

                    Credit scores

                    This is where FHA earns its reputation. FHA will work with scores down to 580 (and even 500 with more down), making it a genuine on-ramp for buyers who are still building credit. Conventional loans generally want 620 or higher, and your rate improves as your score climbs. If your credit is thin or bruised, FHA is often the door that opens first.

                    Mortgage insurance — the part that costs you long-term

                    Both loans charge insurance when you put down less than 20%, but they behave completely differently:

                    On a conventional loan, PMI cancels — you can request removal at 20% equity, and it's legally automatic at 22%. On an FHA loan, MIP typically lasts the life of the loan when you put down less than 10%, plus there's a 1.75% upfront premium at closing. That long tail is the single most overlooked cost difference between the two.

                    Loan limits

                    Both are "conforming" loans with caps set each year. For 2025, the baseline conventional limit for a single-family home is $806,500, rising to $1,209,750 in high-cost areas. FHA sets its own floor and ceiling by county. If you're shopping above these limits, you're into jumbo territory — a different conversation entirely.

                    So which one?

                    If your credit is still climbing or your savings are tight, FHA is often the way in. If you've got a 620+ score and want to avoid paying insurance for decades, conventional usually wins on total cost — especially since you can put as little as 3% down as a first-time buyer. The smartest move is to price out both, insurance included, before you commit.

                      Built for buyers. Not lenders.

                      Calculate My Rate is an independent educational platform that gives every home buyer the clarity, confidence and tools to navigate the mortgage process, without the pressure, the pitch or the confusion.

                      Going through the home-buying process can feel overwhelming. Between rate quotes, LLPA adjustments, closing cost breakdowns and Loan Estimates full of terms you've never heard, it's easy to feel like the whole system is designed for everyone but you.

                      We went through it ourselves. We sat across from lenders without knowing what questions to ask, signed documents we didn't fully understand, and wished there had been a place to go just to understand the numbers, without anyone trying to sell us something.

                      That's exactly what Calculate My Rate is. We built the tools we wished existed, and we made them free for everyone, because financial clarity shouldn't be a luxury.

                      Is this financial advice?

                      No. Everything on Calculate My Rate (the calculators, articles, glossary and guides) is for educational purposes only. We help you understand the numbers so you can ask better questions. Nothing here is a recommendation to buy, sell, borrow or invest. Always work with a licensed lender, financial advisor or real estate professional for advice specific to your situation.

                      Are the rate estimates accurate?

                      The rates in our calculator are educational estimates based on publicly available LLPA data and general market conditions. They are not a quote, not a commitment to lend, and not guaranteed. Your actual rate depends on your full financial profile, the lender you choose, and the market when you lock. Always get a formal Loan Estimate from a licensed lender for your actual numbers.

                      Do you pitch me a loan?

                      No. We don't make loans or pitch you one. We're an independent educational platform with no mortgage product to sell and no lender relationship that influences what we show you. No pressure, no follow-up calls, no agenda.

                      What is an LLPA, and why does it affect my rate?

                      A loan-level price adjustment (LLPA) is a risk-based fee Fannie Mae and Freddie Mac charge on most conventional mortgages. It's based on your credit score, down payment, property type and other factors, and it's folded into your interest rate instead of shown as a separate charge. Our LLPA adjuster shows you exactly which cell of the pricing grid you land in.

                      Can I use these tools if I'm just starting to research?

                      Absolutely. That's exactly who we built them for. You don't need a lender, a pre-approval, or even a specific home in mind. The tools work best before you talk to lenders, so you know what questions to ask and what numbers to expect.

                      Why does my rate look different from a lender's quote?

                      That's expected. Our calculator gives you an educational estimate so you know the ballpark before you walk in. A lender's quote reflects your full credit file, the specific loan program, their own pricing and that day's market. Use our numbers to understand what drives your rate, then compare real Loan Estimates across lenders.

                      Who made this, and why?

                      Calculate My Rate was built by people who went through the home-buying process and felt blindsided by how complicated, and how opaque, mortgage pricing really is. We built the tools we wished had existed. When buyers understand their numbers, they make better decisions and ask better questions.
